     DETAILED DESCRIPTION TO EXECUTE THE INVENTION 
     Description of Embodiments of the Present Disclosure 
     Firstly, embodiments of the present disclosure will be listed and described. 
     A connector-equipped wire according to this disclosure is as follows. 
     (1) A connector-equipped wire includes a terminal-equipped wire that includes a coated wire and a terminal component provided at an end portion of the coated wire, and a connector housing that includes a main body component provided with a cavity, and a cover component mounted to the main body component, in which a leading end portion of the terminal component is accommodated in the cavity, a rear end portion of the terminal component protrudes outward of the cavity and is covered by the cover component or by the cover component and the main body component, and the cover component is mountable to the main body component through sliding movement in a direction that intersects a longitudinal direction of the cavity in a state in which the rear end portion of the terminal component protrudes outward of the cavity. When the terminal component is inserted into the cavity of the main body component before the cover component is mounted, the amount by which the terminal component is inserted into the cavity is reduced. When the cover component is mounted to the main body component after the terminal component has been inserted into the cavity, the rear end portion of the terminal component is covered. As a result, the terminal-equipped wire can be easily accommodated in the connector housing. 
     (2) In the connector-equipped wire according to (1), the cover component may include a first cover component and a second cover component that are mountable through sliding movement in directions that intersect each other with respect to the main body component in a state in which the rear end portion of the terminal component inserted into the cavity protrudes outward of the cavity, and the first cover component may include a first wall portion covering a portion of the rear end portion of the terminal component that extends in a circumferential direction thereof, and the second cover component may include a second wall portion covering another portion of the rear end portion of the terminal component that extends in the circumferential direction. As a result, the entire circumference of the rear end portion of the terminal component can be covered by two cover components mounted to the main body component. 
     (3) In the connector-equipped wire according to (1), the main body component may include a first wall portion that is formed on an end surface provided with one opening portion of the cavity and that covers another portion of the rear end portion of the terminal component that extends in the circumferential direction, and the cover component may include a second wall portion that covers a portion of the rear end portion of the terminal component that extends in the circumferential direction. As a result, one cover component is mounted to the main body component, and the entire circumference of the rear end portion of the terminal component can be covered by the main body component and the cover component. 
     (4) In the connector-equipped wires according to any one of (1) to (3), the main body component and the cover component may be respectively provided with a fitting portion and a fitted portion for maintaining a mounted state, the fitting portion may be fitted to the fitting portion in the direction of sliding movement of the main body component and the cover component, the direction intersecting the longitudinal direction of the cavity. As a result, the fitting portion and the fitted portion can be fitted to each other through sliding movement of the main body component and the cover component in the direction that intersects the longitudinal direction of the cavity. 
     (5) In the connector-equipped wire according to any one of (1) to (4), the terminal-equipped wire may further include a seal member mounted to an intermediate portion of the terminal component, the seal member may be disposed in the cavity, and a rear end portion of the terminal component, which is located rearward of a portion where the seal member is mounted, protrudes outward from the cavity. Accordingly, the amount by which the seal member moves in the cavity is reduced. As a result, the terminal-equipped wire can be easily accommodated in the connector housing. 
     (6) In the connector-equipped wire according to (5), a portion of the cavity where the seal member is disposed may have a circular transverse cross-sectional shape, and the rear end portion of the terminal component may be covered by four wall portions, and the four wall portions may be combined together to form a rectangular tubular shape. As a result, the seal member and the inner surface of the cavity are more likely to be in intimate contact with each other. Also, the shape of the wall portions covering the rear end portion of the terminal component results in a simple shape. 
     (7) Further, the connector housing according to this disclosure is a connector housing in which a terminal-equipped wire whose end portion is provided with a terminal component is to be accommodated, the connector housing including a main body component provided with a cavity into which a leading end portion of the terminal component is insertable, and a cover component mounted to the main body component, in which a rear end portion of the terminal component protrudes outward of the cavity and is covered by the cover component or by the cover component and the main body component, and the cover component is mountable to the main body component through sliding movement in a direction that intersects a longitudinal direction of the cavity in a state in which the rear end portion of the terminal component protrudes outward of the cavity. When the terminal component is inserted into the cavity of the main body component before the cover component is mounted, the amount by which the terminal component is inserted into the cavity is reduced. When the cover component is mounted to the main body component after the terminal component has been inserted into the cavity, the rear end portion of the terminal component is covered. As a result, the terminal-equipped wire can be easily accommodated in the connector housing.

The spring contact portion or the like is connected to the conductor pin in the female counterpart terminal. 
     The relay conductor connection portion  42  includes a wire barrel  43  and an insulation barrel  44 . The wire barrel  43  is crimped to the relay conductor  46 . The insulation barrel  44  is crimped to the seal member  50 . The insulation barrel  44  may be omitted from the relay conductor connection portion  42 . 
     The relay conductor  46  is formed as a single conductor. The relay conductor  46  is formed in a round columnar rod shape. The relay conductor  46  may also be formed in a cylindrical rod shape. The relay conductor  46  is longer than the seal member  50 . Two end portions in the longitudinal direction of the relay conductor  46  protrude outward of the seal member  50 . Two end portions of the relay conductor  46  are respectively crimped to the wire barrels  37  and  43 . 
     The terminal-equipped wire  20  is provided with a mounting portion  48 . The seal member  50  is mounted to the mounting portion  48 . The outer surface of the mounting portion  48  has a circular shape. An intermediate portion extending in the longitudinal direction of the relay conductor  46  serves as the mounting portion  48 . 
     Here, the terminal-equipped wire  20  also includes the seal member  50 . The seal member  50  is mounted to the intermediate portion of the terminal component  30 . The seal member  50  is mounted to the mounting portion  48 . The seal member  50  is also accommodated in the accommodation space in the connector housing  60 . Here, the seal member  50  is accommodated in the cavity  63  in the accommodation space. 
     The seal member  50  includes a seal main body  52  and held portions  54 . The seal member  50  is provided with a through-hole  56 . The relay conductor  46  is passed through the through-hole  56 . The seal main body  52  and the held portions  54  are aligned in the axial direction of the through-hole  56 . Here, the held portions  54  are respectively provided on two sides of the seal main body  52 . A held portion  54  may be provided on only one side of the seal main body  52 . The held portions  54  may be omitted. 
     The seal main body  52  stops a liquid from moving between one opening portion and the other opening portion of the cavity  63  in a state in which the terminal-equipped wire  20  is inserted into the cavity  63 . An annular recess and an annular protrusion are alternately continuous with each other in the longitudinal direction on the outer surface of the seal main body  52 . The seal main body  52  is positioned between the joint terminal  32  and the connector terminal  40  in the longitudinal direction. The annular protrusions on the seal main body  52  protrude outward of the joint terminal  32  and the connector terminal  40  in a radial direction. 
     The outer diameter of the seal main body  52  is the same as or larger than the inner diameter of the cavity  63  before the terminal-equipped wire  20  is inserted into the cavity  63 . The annular protrusions of the seal main body  52  are in intimate contact with the circumferential surface of the cavity  63  over the entire circumferential direction thereof in the accommodated state. 
     The held portions  54  are respectively crimped to the insulation barrels  38  and  44  in a state in which the held portions  54  cover the relay conductor  46 . As a result, the held portions  54  are positioned and held by the connector terminal  40  and the joint terminal  32 , and the seal member  50  is positioned and held by the terminal-equipped wire  20 . If the held portions  54  are omitted, the mounting portion  48  is preferably shaped so as to be capable of positioning and holding the seal member  50 . A groove may be formed in the mounting portion  48 , for example. When the seal member  50  is accommodated in the groove, the seal member  50  is positioned and held by the mounting portion. 
     The seal member  50  is accommodated in the cavity  63  in the accommodated state. Provision of the seal member  50  stops a liquid from moving between one opening portion and the other opening portion of the cavity  63 . Water, oil, and the like are envisioned as liquids to be stopped by the seal member  50 . Examples of oil include oil (hydraulic oil) for performing automatic shift control operations in an automatic transmission. Liquid is stopped from moving between one opening portion and the other opening portion of the cavity  63  as follows, for example. 
     The mounting portion  48  is solid. This inhibits liquid from flowing through the mounting portion  48  and permeating from one of the one opening portion and the other opening portion of the cavity  63  to the other of the one opening portion and the other opening portion. The mounting portion  48  may be hollow. In this case, it is also possible to inhibit liquid from flowing through the mounting portion  48  and permeating from one of the one opening portion and the other opening portion of the cavity  63  to the other of the one opening portion and the other opening portion, as long as at least one side of the mounting portion  48  in the longitudinal direction is closed. 
     The inner surface (the inner circumferential surface of the through-hole  56 ) of the seal main body  52  is circular. In the accommodated state, the entire inner surface of the seal main body  52  is in intimate contact with the outer surface of the mounting portion  48  in the circumferential direction thereof. Thus, the seal main body  52  inhibits liquid from flowing between the seal main body  52  and the mounting portion  48  and permeating from one of the one opening portion and the other opening portion of the cavity  63  to the other of the one opening portion and the other opening portion. Note that it is sufficient that the entire inner circumferential surface of at least a portion of the seal main body  52  extending in the longitudinal direction thereof is in intimate contact with the outer surface of the mounting portion  48 . The inner surface of the seal main body  52  may be formed smaller than the outer surface of the mounting portion  48  before the seal main body  52  is mounted to the mounting portion  48 . The inner surface of the seal main body  52  may be pressed against the outer surface of the mounting portion  48  when subjected to pressure from the cavity  63  in the accommodated state. 
     The outer surface of the seal main body  52  is circular. The outer surfaces of the annular protrusions of the seal main body  52  are in intimate contact with the circumferential surface of the cavity  63  over the entire circumferential direction thereof in the accommodated state. This inhibits liquid from flowing between the seal main body  52  and the connector housing  60  and permeating from one of the one opening portion and the other opening portion of the cavity  63  to the other of the one opening portion and the other opening portion. 
     The seal member  50  is disposed in the cavity  63 . The rear end portion of the terminal component  30 , which is located rearward of a portion where the seal member  50  is mounted, protrudes outward from the cavity  63 . Here, an end portion of the relay conductor  46  and the joint terminal  32  are positioned outside the cavity  63 . 
     Connector Housing 
     The connector housing  60  will be described in detail with reference to  FIGS.  3    to  5 , in addition to  FIG.  1   .  FIG.  3    is a perspective view showing the connector housing  60  according to Embodiment 1.  FIG.  4    is an exploded perspective view showing the connector housing  60  according to Embodiment 1.  FIG.  5    is an exploded perspective view showing the connector housing  60  according to Embodiment 1.  FIGS.  3  and  4    are perspective views of the connector housing  60  as seen in the same direction, and  FIG.  5    is a perspective view of the connector housing  60  as seen in a direction that is different from that in  FIGS.  3  and  4   . 
     The connector housing  60  includes the main body component  61 , and the cover components  70  and  80  that are mounted to the main body component  61 . 
     The main body component  61  includes a housing main body  62 . Here, the main body component  61  also includes first fitting portions  66 . The main body component  61  is formed using insulating resin as a material. The main body component  61  is an injection molded component, for example. 
     The housing main body  62  is provided with the cavities  63 . At least one cavity  63  is formed. Here, a plurality of cavities  63  are formed. A plurality of cavities  63  are formed so as to be aligned in a plurality of rows and columns. A plurality of cavities  63  may be also formed so as to be aligned in one row and a plurality of columns In  FIG.  4   , the Z-direction refers to the column direction, and the Y-direction refers to the row direction. In the example shown in  FIG.  4   , a plurality of cavities  63  are formed so as to be aligned in four rows and five columns. 
     The cavities  63  are formed to extend through the housing main body  62 . One opening portion of each cavity  63  is open on one end surface (end surface facing the negative side in the X-direction) of the housing main body  62 . The other opening portion of the cavity  63  is open on the other end surface (end surface facing the positive side in the X-direction) of the housing main body  62 . 
     The terminal-equipped wire  20  is inserted into the cavity  63  from the one opening portion. The terminal-equipped wire  20  and the housing main body  62  are positioned and held at predetermined positions by a lance or the like, for example. The other opening portion is a portion through which a conductor pin provided on the male terminal is passed. Note that this example is a case in which a terminal accommodated in the cavity  63  is a male terminal. In this case, the conductor pin provided on the male terminal passes through the other opening portion and protrudes outward of the cavity  63 . Then, the conductor pin provided on the male terminal and the female counterpart terminal are connected to each other, outside the cavity  63 . Preferably, the other opening portion is smaller than the box-shaped portion of the counterpart connection portion  41 , and is larger than the conductor pin. As a result, the male terminal accommodated in the cavity  63  is kept from falling out from the other opening portion. Naturally, the terminal accommodated in the cavity  63  may be a female terminal. In this case, the conductor pin provided on a male terminal of the counterpart connector is passed through the other opening portion and is inserted into the cavity  63 . Then, the female terminal and the conductor pin provided on the male counterpart terminal are connected to each other in the cavity  63 . 
     The seal member  50  is also disposed at a predetermined position in the cavity  63  in a state in which the terminal-equipped wire  20  is disposed at a predetermined position in the cavity  63 . Here, the transverse cross-sectional shape of a portion of the cavity  63  where the seal member  50  is disposed is circular. As shown in  FIG.  4   , the transverse cross-sectional shape of the one opening portion of the cavity  63  is circular in this embodiment. The transverse cross-sectional shape extending from the one opening portion of the cavity  63  to the portion where the seal member  50  is disposed is circular. The transverse cross-sectional shape of the cavity  63  extending from the portion where the seal member  50  is disposed to the other opening portion is set as appropriate. 
     The main body component  61  is provided with protruding wall portions  64 . The protruding wall portions  64  protrude from the one end surface provided with the one opening portions of the cavities  63 . The protruding wall portions  64  are provided between cavities  63  that are aligned in the column direction. The protruding wall portions  64  are displaced in the Z-direction with respect to the cavities  63 . The protruding wall portions  64  are provided so as to cover portions that cannot be covered by the second cover component  80 . The protruding wall portions  64  may be omitted. The protruding length (the length in the X-direction) of each protruding wall portion  64  is approximately the same as the distance between a leading end of a slit  72  in the first cover component  70  and an end surface of the first cover component  70 . The width (the length in the Y-direction) of the protruding wall portion  64  is approximately the same as the width of the cavity  63 . The thickness (the length in the Z-direction) of the protruding wall portion  64  is the same as or slightly smaller than the length of the gap present between two cavities  63 . 
     Note that the distance between the cavities  63  in the second row and the cavities  63  in the third row is larger than the distance between cavities in other rows in this embodiment. Thus, two protruding wall portions  64  are provided between a cavity  63  in the second row and a cavity  63  in the third row. 
     The main body component  61  is provided with a protruding frame portion  65 . The protruding frame portion  65  positions the first cover component  70 . The protruding frame portion  65  protrudes from the one end surface provided with the one opening portions of the cavities  63 . The protruding frame portion  65  is provided so as to surround the plurality of cavities  63 . One side (the positive side in the Z-direction) of the protruding frame portion  65  is open. The first cover component  70  is inserted via this opening into the protruding frame portion  65 . Similarly to the protruding length of the protruding wall portions  64 , the protruding length (the length in the X-direction) of the protruding wall portion  64  is approximately the same as the distance between the leading end of the slit  72  in the first cover component  70  and the end surface of the first cover component  70 .

     The first wall portions  71  cover portions of the rear end portions of the terminal components  30  extending in the circumferential direction. Here, the first wall portions  71  cover the rear end portion of the corresponding terminal component  30  from two sides in the Y-direction. Each first wall portion  71  is formed in a flat plate shape that expands along the XZ plane. Here, because the cavities  63  are provided in five columns, six first wall portions  71  are provided. Among the six first wall portions  71 , four first wall portions  71   a  are provided between the cavities  63  arranged in five columns. The four first wall portions  71   a  separate columns of the plurality of cavities  63 . Similarly to the thickness of the protruding wall portion  64 , the thickness of the four first wall portions  71   a  is approximately the same as the size of the gap between two cavities  63 . Among the six first wall portions  71 , two first wall portions  71   b  are provided outside the five columns of the cavities  63 . The two first wall portions  71   b  surround the plurality of cavities  63 . 
     Each first wall portion  71  is provided with slits  72 . Each slit  72  extends from an end surface of the first wall portion  71  on the negative side in the X-direction to the positive side in the X-direction. The slit  72  does not reach the end surface of the first wall portion  71  on the positive side in the X-direction. The slit  72  is provided between cavities  63  that are aligned in the row direction. The slit  72  is provided at a position corresponding to the protruding wall portion  64 . A second wall portion  81 , which will be described later, is passed through the corresponding slit  72 . The length in the X-direction from the end surface of the first wall portion  71  on the positive side in the X-direction to the leading end of the slit  72  is approximately the same as the dimension of the protruding wall portion  64 . 
     The first connection wall portion  73  connects the plurality (six in this embodiment) of first wall portions  71  to each other. The first connection wall portion  73  is formed in a flat plate shape that expands along the XY plane. The end surface of each first wall portion  71  on the positive side in the Z-direction is connected to a surface of the first connection wall portion  73  facing the negative side in the Z-direction. The first wall portions  71  protrude from the surface of the first connection wall portion  73  facing the negative side in the Z-direction to the negative side in the Z-direction. In this embodiment, no slit  72  is formed in the first connection wall portion  73 . In this embodiment, the first connection wall portion  73  covers, from the Z-direction, the rear end portions of the terminal components  30  inserted into the cavities  63  in the first row (the uppermost row in  FIG.  4   ). 
     The first fitted portions  74  are fitted to first fitting portions  66 . The first fitting portions  66  and the first fitted portions  74  maintain the state in which the first cover component  70  is mounted to the main body portion. The first fitting portions  66  are fitted to the first fitted portions  74  in the direction (the Z-direction in this embodiment) of sliding movement of the main body component  61  and the first cover component  70 , the direction intersecting the longitudinal direction (the X-direction in this embodiment) of the cavities  63 . 
     More specifically, the first fitted portions  74  are respectively provided outside the two first wall portions  71 . Each first fitted portion  74  is provided on the end surface side of the first wall portions  71  where no slits  72  are formed. Each first fitted portion  74  is provided in a rectangular parallelepiped elongated in the Z-direction. 
     Each first fitting portion  66  includes a protruding piece  66   a  and a protrusion  66   b.  The protruding piece  66   a  protrudes in the Z-direction from an end portion of the protruding frame portion  65  while being spaced apart from the one end surface of the housing main body  62 . The protruding piece  66   a  is provided in the manner of a cantilever. The protrusion  66   b  is provided on a portion of the one end surface of the housing main body  62  that faces the protruding piece  66   a.  The protrusion  66   b  protrudes in the X-direction toward the protruding piece  66   a.  The first fitted portion  74  is inserted between the protruding piece  66   a  and the protrusion  66   b.  A guide surface is provided on a surface (a surface facing the positive side in the Z-direction) of the protrusion  66   b  and the protruding piece  66   a  on a side from which the first fitted portion  74  is inserted. 
     The protrusion  66   b  is formed in a rectangular parallelepiped shape, which corresponds to the shape of the first fitted portion  74 , in which a portion that includes one corner portion is cut out. The one corner portion is a corner portion located on the negative side in the Z-direction of the protrusion  66   b  and on the center side of the housing main body  62  in the Y-direction. The first fitted portion  74  is accommodated in the cut out portion of the protrusion  66   b.  The remaining portion of the protrusion  66   b  on the positive side in the Z-direction with respect to the cut out portion serves as a step portion  66   c.  The step portion  66   c  presses the rear side of the first fitted portion  74  inserted into the first fitting portion  66 . This inhibits the first cover component  70  from detaching from the main body component  61  to the positive side in the Z-direction. The protruding frame portion  65  presses the front side of the first fitted portion  74  inserted into the first fitting portion  66 . 
     The remaining portion of the protrusion  66   b  on the outer side of the housing main body  62  in the Y-direction with respect to the cut out portion serves as a step portion  66   d.  The step portion  66   d  presses the lateral side of the first fitted portion  74  inserted into the first fitting portion  66 . As a result, the first cover component  70  and the main body component  61  are positioned in the Y-direction. 
     The protruding frame portion  65  of the main body component  61  and the wall portion of the first cover component  70  are in contact with each other in the Y-direction and the Z-direction. As a result, the first cover component  70  and the main body component  61  are positioned in the Y-direction, and the first cover component  70  is kept from detaching from the main body component  61  to the negative side in the Z-direction. 
     The second fitting portions  75  and  76  are fitted to second fitted portions  83  provided on the second cover component  80 . The second fitting portions  75  and  76  will be described later in detail together with the second fitted portions  83 . 
     The second cover component  80  is mounted to the first cover component  70 . Therefore, the second cover component  80  is mounted to the main body component  61  via the first cover component  70 . The first cover component  70  and the second cover component  80  are mountable to the main body component  61  through sliding movement in directions (the Y-direction in this embodiment) that intersect each other in a state in which the rear end portions of the terminal components  30  inserted into the cavities  63  protrude outward of the cavities  63 . The second cover component  80  includes the second wall portion  81  and a second connection wall portion  82 . Here, the second cover component  80  also includes the second fitted portions  83 . Here, the second cover component  80  also includes a wire regulating portion  84 . The second cover component  80  is formed using insulating resin or the like as a material. The second cover component  80  is an injection molded component, for example. 
     The second wall portion  81  covers the other portion of the rear end portions of the terminal components  30  extending in the circumferential direction. Here, the second wall portion  81  covers the rear end portions of the terminal components  30  from the Z-direction. The second wall portion  81  is formed in a flat plate shape that expands in the XY plane. Six second wall portions  81  are provided. Among the six second wall portions  81 , four second wall portions  81   a  are provided between the cavities  63  arranged in four rows. Although the cavities  63  are provided in four rows in this embodiment, because the distance between the second row and the third row is long, two second wall portions  81   a  are provided therebetween. Four second wall portions  81   a  are inserted into the slits  72 . The four second wall portions  81   a  separate the rows of the cavities  63 . Similarly to the thickness of the protruding wall portion  64 , the thickness of the four second wall portions  81   a  is approximately the same as the size of the gap present between two cavities  63 . Among the six second wall portions  81 , two second wall portions  81   b  are provided outside the four rows of the cavities  63 . The two second wall portions  81   b  surround the plurality of cavities  63 . Note that the two second wall portions  81   b  surround the first cover component  70  in this embodiment. One of the two second wall portions  81   b  is provided outside the first connection wall portion  73 . Thus, one of the two second wall portions  81   b  does not face the terminal components  30 . 
     The second connection wall portion  82  connects the six second wall portions  81 . The second connection wall portion  82  is formed in a curved plate shape that corresponds to one end surface of the housing main body  62 . The second wall portion  81  and the second connection wall portion  82  are positioned on the negative side in the Z-direction relative to the protruding frame portion  65 . 
     Two second fitted portions  83  are provided. The two second fitted portions  83  are respectively fitted to the second fitting portions  75  and  76 . The second fitting portions  75  and  76  and the second fitted portions  83  maintain the state in which the first cover component  70  and the second cover component  80  are mounted to the main body component  61 . The second fitting portions  75  and  76  are fitted to the second fitted portions  83  in the direction (the Y-direction in this embodiment) of sliding movement of the first cover component  70  and the second cover component  80  in a direction that intersects the longitudinal direction of the cavities  63 . 
     More specifically, the second fitted portions  83  are provided on the inner side of the two second wall portions  81   b.  Portions of the two second wall portions  81   b  protrude outward in the Z-direction. Grooves  83   a  are formed on the inner side of the protruding portions. The grooves  83   a  extend in the Y-direction. An end portion of each groove  83   a  is provided with a fitting hole  83   b.    
     The second fitting portion  75  is provided on the outer surface of the first connection wall portion  73 . The second fitting portion  75  includes a protrusion  75   a  and a retaining piece  75   b.  The protrusion  75   a  is formed in a rectangular parallelepiped elongated in the Y-direction. The protrusion  75   a  extends from the end surface of the first connection wall portion  73  on the negative side in the Y-direction to an intermediate portion of the first connection wall portion  73  in the Y-direction. The retaining piece  75   b  is provided at a leading end of the protrusion  75   a.  The retaining piece  75   b  protrudes father in the Z-direction than the protrusion  75   a.    
     The second fitting portion  76  is provided on the end surface of the first wall portion  71  on the negative side in the Z-direction. The second fitting portion  76  includes four protrusions  76   a  that respectively protrude from four first wall portions  71 , and retaining pieces  76   b  that are each provided on one of the four protrusions  76   a.  The second fitting portion  76  is formed in a shape in which a portion between first wall portions  71  is cut out from the second fitting portion  75 . 
     The second fitting portions  75  and  76  are inserted into the second fitted portions  83  via the grooves  83   a.  When retaining pieces  75   b  and  76   b  pass through the fitting holes  83   b  and are fitted to peripheral edge portions of the fitting holes  83   b,  the second fitting portions  75  and  76  are fitted to the second fitted portions  83 . 
     The wire regulating portion  84  regulates the route of the coated wire  22  that extends outward of the accommodation space. In this embodiment, the wire regulating portion  84  bends the coated wires  22 , which extend from the accommodation space to the negative side in the X-direction, to the negative side in the Y-direction. Specifically, the wire regulating portion  84  includes a guide portion  84   a  and a regulating portion  84   b.  The guide portion  84   a  is formed so as to be inclined from the two second wall portions  81   b  and the second connection wall portion  82  toward the regulating portion  84   b.  The guide portion  84   a  is formed such that a transverse cross-section thereof gradually decreases. The coated wires  22  that extend from the accommodation space in the Z-direction in a spread out state are gathered in the Z-direction by the guide portion  84   a.  The regulating portion  84   b  is formed in a frame shape in which a portion connected to the guide portion  84   a  and a portion facing the negative side in the Y-direction are open. The regulating portion  84   b  covers the negative side in the X-direction of the coated wires  22 . As a result, the coated wires  22  are bent to the negative side in the Y-direction. The wire regulating portion  84  need not be provided in the connector housing  60 . 
     Method for Manufacturing Connector-Equipped Wire 
     When the connector-equipped wire  10  is to be manufactured, first, the terminal-equipped wire  20  and the disassembled connector housing  60  are prepared. Then, the terminal-equipped wire  20  is inserted into the main body component  61 . At this time, because the length of the cavity  63  of the main body component  61  is shorter than the length of the terminal component  30 , the amount by which the terminal-equipped wire  20  is inserted into the cavity  63  is reduced. Also, on the outer side of the one opening portion of the cavity  63 , in a portion where the protruding wall portion  64  is not provided, the terminal-equipped wire  20  is insertable into the cavity  63  while holding the terminal component  30 . As a result, when the terminal-equipped wire  20  is inserted into the cavity  63 , even if the terminal-equipped wire  20  comes into contact with the inner surface of the cavity  63 , the terminal-equipped wire  20  is unlikely to bend. Also, because a portion in which the seal member  50  is to be accommodated is present at a position close to the one opening portion of the cavity  63 , the amount by which the seal member  50  moves in the cavity  63  is reduced. As a result, the terminal-equipped wires  20  can be easily inserted into the cavities  63 . 
     Once the terminal-equipped wires  20  have been inserted into the main body component  61 , as shown in  FIGS.  6  and  7   , the first cover component  70  is mounted to the main body component  61 .  FIGS.  6  and  7    are diagrams illustrating how the first cover component  70  is mounted to the main body component  61 .  FIG.  6    is a cross-sectional view, and  FIG.  7    is a front view. 
     The first cover component  70  is mounted to the main body component  61  through sliding movement from the negative side in the Z-direction. Here, four first wall portions  71  are inserted between the terminal components  30  and the protruding wall portions  64  that are aligned in the column direction. Also, two first wall portions  71  are inserted between the protruding frame portion  65  and the protruding wall portions  64  and the terminal components  30 . Further, the first fitted portions  74  are respectively inserted into the first fitting portions  66 . At this time, the first cover component  70  can be mounted to the main body component  61  by sliding the first cover component  70  in a state in which the end surface of the first cover component  70  on the positive side in the X-direction faces the one end surface of the housing main body  62 . Also, at this time, the main body component  61  and the first cover component  70  are fitted so as to face each other by inserting the first wall portions  71  before the first fitted portions  74  are inserted. Accordingly, the first cover component  70  can be easily mounted to the main body component  61 . 
     Once the first cover component  70  has been mounted to the main body component  61 , as shown in  FIGS.  8  and  9   , the second cover component  80  is mounted to the first cover component  70 .  FIGS.  8  and  9    are diagrams illustrating how the second cover component  80  is mounted to the first cover component  70 .  FIG.  8    is a cross-sectional view, and  FIG.  9    is a front view. 
     The second cover component  80  is mounted to the first cover component  70  mounted to the main body component  61  through sliding movement from the positive side in the Y-direction. Here, four second wall portions  81  are inserted into the slits  72 . Four second wall portions  81  are inserted between terminal components  30  that are aligned in the row direction. Also, the first cover component  70  is inserted between two second wall portions  81 . Further, the second fitting portions  75  and  76  are respectively inserted into the second fitted portions  83 . At this time, the second cover component  80  can be mounted to the first cover component  70  by sliding the second cover component  80  in a state in which the end surface of the second cover component  80  that faces the positive side in the X-direction faces the end surface of the protruding frame portion  65  that faces the negative side in the X-direction. Also, at this time, inserting the second wall portion  81  before inserting the second fitting portions  75  and  76  results in the first cover component  70  and the second cover component  80  being aligned so as to be fitted to each other. Accordingly, the first cover component  70  and the second cover component  80  can be easily mounted to the main body component  61 . 
     When the first cover component  70  and the second cover component  80  are mounted to the main body component  61 , the rear end portion of each terminal component  30  is covered by four wall portions. The four wall portions are combined together to form a rectangular tubular shape. That is, the transverse cross-sectional shape of the space surrounded by four wall portions is a rectangle. Here, a combination of the four wall portions covering the rear end portions of the terminal components  30  changes depending on the positions of the cavities  63  into which the terminal components  30  are inserted, the position where the terminal components  30  protrude from the cavities  63 , and the like. 
     More specifically, of the rear end portion of the terminal component  30  inserted into each cavity  63  in the first row (the uppermost row in  FIG.  9   ), the four sides of a portion near the cavity  63  are covered by two first wall portions  71 , one protruding wall portion  64 , and one first connection wall portion  73 . Of the rear end portion of the terminal component  30  inserted into each cavity  63  in the first row, the four sides of a portion distant from the cavity  63  are covered by two first wall portions  71 , one second wall portion  81 , and one first connection wall portion  73 . 
     Of the rear end portion of the terminal component  30  inserted into each cavity  63  in the second row and the third row (the second row and the third row from top in  FIG.  9   ), the four sides of a portion near the cavity  63  are covered by two first wall portions  71  and two protruding wall portions  64 . Of the rear end portion of the terminal component  30  inserted into each cavity  63  in the second row and the third row, the four sides of a portion distant from the cavity  63  are covered by two first wall portions  71  and two second wall portions  81 . 
     Of the rear end portion of the terminal component  30  inserted into each cavity  63  in the fourth row (in the lowest row in  FIG.  9   ), the four sides of a portion near the cavity  63  are covered by two first wall portions  71 , one protruding wall portion  64 , and one protruding frame portion  65 . Of the rear end portion of the terminal component  30  inserted into each cavity  63  in the fourth row, the four sides of a portion distant from the cavity  63  are covered by two first wall portions  71  and two second wall portions  81 . 
     Effects etc., of Embodiment 1 
     According to the connector-equipped wire  10  configured as described above, as a result of the terminal components  30  being inserted into the cavities  63  of the main body component  61  before the cover components  70  and  80  are mounted, the amount by which the terminal components  30  are inserted into the cavities  63  is reduced. When the cover components  70  and  80  are mounted to the main body component  61  after the terminal components  30  have been inserted into the cavities  63 , the rear end portions of the terminal components  30  are covered. As a result, the terminal-equipped wires  20  can be easily accommodated in the connector housing  60 . 
     Also, the entire circumference of the rear end portions of the terminal components  30  can be covered by the first wall portions  71  provided on the first cover component  70 , and the second wall portions  81  provided on the second cover component  80 . As a result, the entire circumference of the rear end portions of the terminal components  30  can be covered by the two cover components  70  and  80  mounted to the main body component  61 . 
     Also, the first fitting portions  66  are fitted to the first fitted portions  74  in the direction of sliding movement of the main body component  61  and the first cover component  70 , the direction intersecting the longitudinal direction of the cavities  63 . As a result, the first fitting portions  66  can be fitted to the first fitted portions  74  during sliding movement of the main body component  61  and the first cover component  70  in the direction that intersects the longitudinal direction of the cavities  63 . Similarly, the second fitting portions  75  and  76  are fitted to the second fitted portions  83  in the direction of sliding movement of the first cover component  70  and the second cover component  80 , the direction intersecting the longitudinal direction of the cavities  63 . As a result, the second fitting portions  75  and  76  can be fitted to the second fitted portions  83  during sliding movement of the first cover component  70  and the second cover component  80  in the direction that intersects the longitudinal direction of the cavities  63 . 
     The seal member  50  is disposed in the cavity  63 , and the rear end portion of the terminal component  30 , which is located rearward of the portion where the seal member  50  is mounted, protrude outward from the cavity  63 . As a result, the amount by which the seal member  50  moves in the cavity  63  is reduced. Accordingly, the terminal-equipped wires  20  can be easily accommodated in the connector housing  60 . 
     Further, the transverse cross-sectional shape of a portion of the cavity  63  where the seal member  50  is disposed is circular. As a result, the inner surfaces of the cavities  63  are likely to be in intimate contact with the seal member  50 . Also, the four wall portions covering the rear end portions of the terminal components  30  are combined together to form a rectangular tubular shape. Accordingly, the shape of the wall portions covering the rear end portions of the terminal components  30  results in a simple shape. 
     Embodiment 2 
     A connector housing according to Embodiment 2 will be described.  FIG.  10    is an exploded perspective view showing a connector housing  160  according to Embodiment 2.  FIG.  11    is a diagram illustrating how the cover component  80  is mounted to a main body component  161 . Note that constituent elements that are the same as those described thus far are given the same reference numerals, and are not described in the following description. 
     The connector housing  160  includes a main body component  161  and a cover component  80 . In the connector housing  160 , the rear end portion of a terminal component  30  also protrudes outward of the cavity  63  of the main body component  161 . Also, the rear end portion of the terminal component  30  is covered by first wall portions  171  and second wall portions  81 . The first wall portions  171  cover a portion of the rear end portion of the terminal component  30  that extends in the circumferential direction, and the second wall portions  81  cover another portion of the rear end portion of the terminal component  30  that extends in the circumferential direction. The connector housing  160  differs from the connector housing  60  in that the number of cover components  80  is one. Because the number of cover components  80  is one, the first wall portions  171  are provided on the main body component  161 . The second wall portions  81  are provided on the cover component  80 . 
     Note that, in the examples shown in  FIGS.  10  and  11   , the main body component  161  has a shape obtained by omitting or adding some constituent elements (e.g., the protruding wall portion  64 , the protruding frame portion  65 , the first fitting portion  66 , and the first fitted portion  74 , and the like) from/to the shape obtained by combining the main body component  61  and the first cover component  70  in Embodiment 1 together. The cover component  80  is the same as the second cover component  80 . Therefore, a first wall portion  171  of the main body component  161  of this example is formed in a shape corresponding to the first wall portion  71  of the first cover component  70 . The second wall portion  81  of the cover component  80  in this example is the same as the second wall portion  81  of the second cover component  80 . 
     As shown in  FIG.  11   , the cover component  80  is mountable to the main body component  161  through sliding movement in a direction (the Y-direction) that intersects the longitudinal direction (the X-direction) of the cavities  63  in a state in which the rear end portions of the terminal components  30  protrude outward of the cavities  63 . As a result, one cover component  80  is mounted to the main body component  161 , and the entire circumference of each rear end portion of the terminal components  30  can be covered by the main body component  161  and the cover component  80 . Also, the main body component  161  and the cover component  80  are fitted to each other using fitting portions  175  and fitted portions  83 . 
     Specifically, the main body component  161  is provided with first wall portions  171 , first connection wall portions  173 , and the fitting portions  175 . The first wall portions  171  and the first connection wall portions  173  protrude from the end surface provided with the one opening portions of the cavities  63 . The cavities  63  in the main body component  161  are provided so as to be aligned in four rows and five columns in the same manner as in Embodiment 1. The first wall portions  171  are arranged such that the slits  72  formed in the first wall portions  71  reach the other end surface of the first wall portions  71  so as to divide the first wall portion  71 . That is, the first wall portions  171  cover two sides of each cavity  63  in the Y-direction. Six first wall portions  171  are provided in one row. The first wall portions  171  that are provided in adjacent rows are spaced apart in the X-direction. 
     Two first connection wall portions  173  are provided. Two first connection wall portions  173  are formed in the same shape as the first connection wall portions  73  in the first cover component  70 . Similarly to the first connection wall portion  73 , one of the two first connection wall portions  173  is located outside the cavities  63  in the first row (the uppermost row in  FIG.  11   ). This first connection wall portion  173  connects the six first wall portions  171  provided adjacent to the cavities  63  in the first row. The other first connection wall portion  173  is located outside the cavities  63  in the fourth row (the lowermost row in  FIG.  11   ). This first connection wall portion  173  connects the six first wall portions  171  provided adjacent to the cavities  63  in the fourth row. 
     Two fitting portions  175  are provided. The two fitting portions  175  are respectively provided on the outer side of the first connection wall portions  173 . The two fitting portions  175  have the same shape as the second fitting portion  75  described above. One of the two fitting portions  175  is formed at the same position as the second fitting portion  75  described above. The other one of the two fitting portions  175  is formed at the same position as the second fitting portion  76  described above. Therefore, the second fitting portion  76  is omitted, and the fitting portions  175  are provided instead. 
     When the cover component  80  is mounted to the main body component  161 , the rear end portion of each terminal component  30  is covered by four wall portions. The four wall portions are combined together to form a rectangular tubular shape. That is, the transverse cross-sectional shape of the space surrounded by the four wall portions is a rectangle. Here, a combination of the four wall portions covering the rear end portions of the terminal components  30  changes depending on the positions of the cavities  63  into which the terminal components  30  are inserted. 
     More specifically, the four sides of the rear end portion of the terminal component  30  inserted into each cavity  63  in the first row (the uppermost row in  FIG.  11   ) and the fourth row (the lowermost row in  FIG.  11   ) are covered by two first wall portions  171 , one second wall portion  81 , and one first connection wall portion  173 . The four sides of the rear end portion of the terminal component  30  inserted into each cavity  63  in the second row and the third row (the second row and the third row from top in  FIG.  11   ) are covered by two first wall portions  171  and two second wall portions  81 . 
     MODIFICATION EXAMPLES 
       FIG.  12    is an exploded perspective view showing a modification example of the connector housing. Although Embodiment 1 was described in which the first fitting portions  66  are fitted to the first fitted portions  74  in the direction of sliding movement of the main body component  61  and the first cover component  70 , the direction intersecting the longitudinal direction of the cavities  63 , this is not a required configuration. As shown in  FIG.  12   , a configuration may be adopted in which the first fitting portions are respectively fitted to the first fitted portions in the longitudinal direction of the cavities  63 . 
     In a connector housing  260  shown in  FIG.  12   , first fitting portions  266  of a main body component  261  are fitted to first fitted portions  274  of a first cover component  270  in the longitudinal direction of cavities  263  (the X-direction in  FIG.  12   ). In this case, first, the first cover component  270  is moved in a direction (the Z-direction in  FIG.  12   ) that intersects the X-direction with respect to the main body component  261  at a position distanced from the main body component  261  in the X-direction, and the first wall portion  271  of the first cover component  270  is inserted between terminal components  30  that protrude from the cavities  263 . Then, the first cover component  270  is moved in the X-direction with respect to the main body component  261 , and the first fitting portions  266  are fitted to the first fitted portions  274 . 
     The first cover component  270  and a second cover component  280  are mounted in the same manner as the first cover component  70  and the second cover component  80 . That is, second wall portions  281  are inserted into slits  272  formed in the first wall portions  271  through sliding movement of the first cover component  270  and the second cover component  280  in the Y-direction. Also, the second fitting portions  275  are fitted to second fitted portions  283  through sliding movement of the first cover component  270  and the second cover component  280  in the Y-direction. The first cover component and the second cover component may also be configured to be fitted to each other in the longitudinal direction of the cavities  263 . Also, if the number of cover components is one as in Embodiment 2, the main body component and the cover component may be configured to be fitted each other in the longitudinal direction of the cavities. 
     Note that the first cover component  270  is provided with seal member mounting portions  277  in the connector housing  260 . The seal member mounting portions  277  are also formed on the first wall portions  271 . Because the first cover component  270  is a component inserted between rear end portions of the terminal components  30  that protrude from the cavities  263 , it is difficult to form a completely circular shape around the X-axis. Thus, the seal member mounting portions  277  are not continuous between the first wall portions  271  in the circumferential direction. 
     Further, although a configuration was described above in which each terminal component  30  includes three components, i.e., the joint terminal  32 , the connector terminal  40 , and the relay conductor  46 , this is not a required configuration. One or both of the joint terminal  32  and the relay conductor  46  may be omitted. If one or both of the joint terminal  32  and the relay conductor  46  are omitted, the wire connection portion  33  is provided on the remaining terminal component  30 . Also, the mounting portion  48  is provided on the terminal component  30  or the conductor core wire  24 . 
     Specifically, if both of the joint terminal  32  and the relay conductor  46  are omitted, the wire connection portion is provided on a connector terminal. The mounting portion may be provided on a connector terminal or the conductor core wire  24 . If the mounting portion is provided on a connector terminal, it is preferable that the mounting portion is formed in an annular shape as is the case with a closed barrel, and a portion of the mounting portion on the counterpart connection portion side is closed. If the mounting portion is provided on the conductor core wire  24 , it is preferable that the conductor core wire  24  is a single core wire constituted by one conductor, and the seal member  50  is mounted to the conductor core wire  24  such that the seal main body is positioned between the insulating sheath  26  and the connector terminal. 
     If one of the joint terminal  32  and the relay conductor  46  is omitted, the function of the omitted one is integrated into the function of the other. The function of the joint terminal  32  may be integrated into that of the relay conductor, for example. In this case, the wire connection portion is provided on the relay conductor. 
     Also, the seal member  50  may be omitted from the terminal-equipped wire  20 . Further, the inner surface of each cavity  63  need not be circular. The inner surface of the cavity  63  may be rectangular or the like. 
     Also, as shown in  FIG.  7   , each protruding wall portion  64  is formed on the main body component  61  in the height direction of the terminal component  30  with respect to the one opening portion of the cavity  63 . Thus, in the main body component  61 , the left and right sides in the left-right direction of the terminal component  30  are open with respect to the one opening portion of the cavity  63 . Note that the height direction of the terminal component  30  refers to a direction in which a crimping piece protrudes from the bottom portion of each barrel, and refers to the Z-direction in the drawings. Also, the left-right direction of the terminal component  30  refers to a direction in which base end portions of two crimping pieces are aligned in each barrel, and refers to the Y-direction in the drawings. As shown in  FIG.  11   , in the main body component  161 , the first wall portions  171  are formed in the left-right direction of the terminal components  30  with respect to the one opening portions of the cavities  63 . Thus, in the main body component  161 , sides in the height direction of each terminal component  30  are open with respect to the one opening portion of the cavity  63 . The protruding wall portions  64  of the main body component  61  may be formed in the left-right direction of the terminal components  30  with respect to the cavities  63 , and sides in the height direction of the terminal components  30  may be open as with the first wall portions  171  of the main body component  161 . Further, the first wall portions  171  of the main body component  161  may be formed in the height direction of the terminal components  30  with respect to the cavities  63 , and sides in the left-right direction of the terminal components  30  may be open as in the protruding wall portions  64  of the main body component  61 . 
     Note that configurations described in the above-described embodiments and modification examples can be combined as appropriate as long as no contradiction arises therein.
