Title: Terminal and wire with terminal

Description:
TECHNICAL FIELD 
     A technique disclosed in this specification relates to a terminal and a wire with terminal. 
     BACKGROUND 
     Conventionally, a wire with terminal is known in which a terminal is connected to a core exposed from an end of a wire. Some of such terminals include, for example, a crimping portion to be crimped to the core exposed from the end of the wire from outside. 
     The above terminal is crimped to the wire, for example, as follows. First, the terminal of a predetermined shape is formed by press-working a metal plate material. Subsequently, the terminal is placed on a placing portion of a lower die located on a lower side, out of a pair of dies relatively movable in a vertical direction. Subsequently, the core exposed from the end of the wire is placed on the crimping portion of the terminal. Thereafter, one or both of the pair of dies is/are moved in mutually approaching direction(s), and the crimping portion is sandwiched between a crimper of the upper die and the placing portion of the lower die, whereby the crimping portion is crimped to the core of the wire. In the above way, the terminal is connected to the end of the wire (see Patent Document 1).

     SUMMARY OF THE INVENTION 
     Problems to be Solved 
     However, according to the above technique, since a relatively large-scale facility such as dies or a jig for crimping the crimping portion of the terminal to the core of the wire is necessary, facility investment is necessary and there is a problem of increasing manufacturing cost. 
     To solve the above problem, it is considered to use a terminal including a terminal body having a sandwiching portion for sandwiching a wire and a tubular slide portion for accommodating this terminal body. The slide portion is provided with a pressurizing portion for pressing the sandwiching portion toward the wire. 
     However, according to the above configuration, there is a concern that the sandwiching portion is bent by the contact of the sandwiching portion and the slide portion in a state before the sandwiching portion is pressed by the pressurizing portion. 
     The technique disclosed in this specification was completed on the basis of the above situation and aims to provide a technique on a terminal with suppressed unintended bending. 
     Means to Solve the Problem 
     The present disclosure is directed to a terminal to be connected to a wire, the terminal including a terminal body having a sandwiching portion for sandwiching the wire, and a tubular slide portion for accommodating the terminal body inside, the slide portion being slidable with respect to the terminal body, wherein the slide portion includes a wide portion located on a front side in a sliding direction of the slide portion and a narrow portion located behind the wide portion in the sliding direction, an inner shape of the slide portion being narrower in the narrow portion than in the wide portion, the narrow portion is provided with a pressurizing portion projecting inwardly of the slide portion, the pressurizing portion presses the sandwiching portion toward the wire with the slide portion slid in the sliding direction with respect to the terminal body and the narrow portion located outside the sandwiching portion, and the slide portion is provided with a restricting portion on a side forward of the pressurizing portion in the sliding direction, the restricting portion restricting bending of the sandwiching portion. 
     Effect of the Invention 
     According to the present disclosure, it is possible to suppress unintended bending of a terminal.

     DETAILED DESCRIPTION TO EXECUTE THE INVENTION 
     Description of Embodiments of Present Disclosure 
     First, embodiments of the present disclosure are listed and described. 
     (1) The terminal of the present disclosure is a terminal to be connected to a wire and includes a terminal body having a sandwiching portion for sandwiching the wire, and a tubular slide portion for accommodating the terminal body inside, the slide portion being slidable with respect to the terminal body, wherein the slide portion includes a wide portion located on a front side in a sliding direction of the slide portion and a narrow portion located behind the wide portion in the sliding direction, an inner shape of the slide portion being narrower in the narrow portion than in the wide portion, the narrow portion is provided with a pressurizing portion projecting inwardly of the slide portion, the pressurizing portion presses the sandwiching portion toward the wire with the slide portion slid in the sliding direction with respect to the terminal body and the narrow portion located outside the sandwiching portion, and the slide portion is provided with a restricting portion on a side forward of the pressurizing portion in the sliding direction, the restricting portion restricting bending of the sandwiching portion. 
     Since the restricting portion is provided on the side forward of the pressurizing portion in the sliding direction of the slide portion, it can be suppressed that the sandwiching portion is bent by contacting the pressurizing portion in a state before the narrow portion is slid to the outside of the sandwiching portion. 
     (2) Preferably, the slide portion is so assembled with the terminal body as to be movable between a full locking position where the pressurizing portion is in contact with the sandwiching portion and a partial locking position where the pressurizing portion is separated from the sandwiching portion, and the bending of the sandwiching portion is restricted by the restricting portion with the slide portion disposed at the partial locking position. 
     Even if the terminal body and the slide portion rattle due to vibration or the like with the slide portion assembled at the partial locking position with the terminal body, unintended bending of the sandwiching portion is suppressed by the restricting portion. 
     (3) Preferably, the slide portion includes a pressurizing wall provided with the pressurizing portion and a slide-side side wall intersecting the pressurizing wall, the restricting portion projects inwardly of the slide portion from an inner surface of the slide-side side wall, and the sandwiching portion passes between the pressurizing wall and the restricting portion when the slide portion slides. 
     Unintended bending of the sandwiching portion can be suppressed when the slide portion slides. 
     (4) Preferably, the slide portion includes a pressurizing wall provided with the pressurizing portion and a slide-side side wall intersecting the pressurizing wall, and a front inclined portion formed to widen an interval between the restricting portion and the pressurizing wall toward a front side in the sliding direction is provided on a front side in the sliding direction of the restricting portion. 
     The sandwiching portion slides in contact with the front inclined portion, thereby being guided between the restricting portion and the pressurizing wall. In this way, unintended bending of the sandwiching portion is suppressed. 
     (5) Preferably, a rear inclined portion inclined in a pressurizing direction of the pressurizing portion to pressurize the sandwiching portion toward a rear side in the sliding direction is provided on a rear side in the sliding direction of the restricting portion. 
     By bending the sandwiching portion along the rear inclined portion, a bending direction of the sandwiching portion can be so controlled that the sandwiching portion is bent in the pressurizing direction toward the rear side in the sliding direction. In this way, the bending of the sandwiching portion in an unintended direction can be suppressed. 
     (6) Preferably, the sandwiching portion is provided with a projection extending in the sliding direction and projecting in the pressurizing direction of the pressurizing portion to pressurize the sandwiching portion or a direction opposite to the pressurizing direction. 
     By providing the projection, the strength of a part not desired to be bent, out of the sandwiching portion, can be improved. In this way, unintended bending of the sandwiching portion can be suppressed. 
     (7) Preferably, the sandwiching portion is provided with an easily bendable portion formed to be narrower than other parts, and the projection is formed to cross the easily bendable portion. 
     To reliably sandwich the wire, the sandwiching portion is preferably bent at a predetermined position. Accordingly, it is considered to reliably bend the sandwiching portion at the predetermined position by providing the sandwiching portion with the easily bendable portion. On the other hand, by providing the easily bendable portion, the easily bendable portion may be buckled at an unintended timing due to vibration or the like. Accordingly, by forming the projection to cross the easily bendable portion, the strength of the easily bendable portion can be adjusted. In this way, the buckling of the easily bendable portion at an unintended timing can be suppressed. 
     (8) Preferably, the terminal body includes a body-side side wall intersecting a wall portion provided with the sandwiching portion, the slide portion includes a slide-side side wall intersecting a pressurizing wall provided with the pressurizing portion, one of the body-side side wall and the slide-side side wall includes an engaging projection projecting toward the other and the other of the body-side side wall and the slide-side side wall includes an engaging recess at a position corresponding to the engaging projection, the engaging projection being accommodated into the engaging recess, and one or both of the engaging projection and the engaging recess extend along the sliding direction. 
     Relative position shifts of the terminal body and the slide portion are suppressed by the contact of the engaging projection accommodated in the engaging recess with the inner wall of the engaging recess. In this way, the rattling of the terminal body and the slide portion by receiving vibration or the like can be suppressed. Further, since the engaging recess extends along the sliding direction, the slide portion can smoothly move along the sliding direction. 
     (9) A wire with terminal of the present disclosure includes the terminal of any one of (1) to (8) described above, and a wire to be connected to the terminal. 
     Details of Embodiments of Present Disclosure 
     Hereinafter, embodiments of the present disclosure are described. The present invention is not limited to these illustrations and is intended to be represented by claims and include all changes in the scope of claims and in the meaning and scope of equivalents. 
     First Embodiment 
     A first embodiment of the present disclosure is described with reference to  FIGS. 1 to 7 . A wire with terminal  10  according to this embodiment includes a wire  11  and a terminal  12  connected to the wire  11 . In the following description, a direction indicated by an arrow Z is an upward direction, a direction indicated by an arrow Y is a forward direction and a direction indicated by an arrow X is a leftward direction. Note that, for a plurality of identical members, only some may be denoted by a reference sign and the others may not be denoted by the reference sign. 
     [Wire  11 ] 
     As shown in  FIG. 1 , the wire  11  is disposed to extend in a front-rear direction (an example of a sliding direction). In the wire  11 , the outer periphery of a core  13  is surrounded with an insulation coating  14  made of insulating synthetic resin. The core  13  according to this embodiment is composed of one metal wire. Note that the core  13  may be a stranded wire formed by twisting a plurality of metal thin wires. An arbitrary metal such as copper, copper alloy, aluminum or aluminum alloy can be appropriately selected as a metal constituting the core  13  if necessary. The core  13  according to this embodiment is made of copper or copper alloy. 
     [Terminal  12 ] 
     As shown in  FIG. 1 , the terminal  12  includes a terminal body  15  made of metal and a slide portion  16  relatively slidable with respect to the terminal body  15 . 
     [Terminal Body  15 ] 
     As shown in  FIG. 1 , the terminal body  15  is formed into a predetermined shape by a known method such as press-working, cutting or casting. An arbitrary metal such as copper, copper alloy, aluminum, aluminum alloy or stainless steel can be appropriately selected as a metal constituting the terminal body  15  if necessary. The terminal body  15  according to this embodiment is made of copper or copper alloy. A plating layer may be formed on the surface of the terminal body  15 . An arbitrary metal such as tin, nickel or silver can be appropriately selected as a metal constituting the plating layer if necessary. Tin plating is applied to the terminal body  15  according to this embodiment. 
     As shown in  FIG. 1 , the terminal body  15  includes a tube portion  17  into which an unillustrated mating terminal is insertable, and a wire connecting portion  20  located behind the tube portion  17  and to be connected to the wire  11 . The wire connecting portion  20  includes an upper sandwiching portion  18 A and a lower sandwiching portion  18 B extending rearward. 
     As shown in  FIG. 1 , the tube portion  17  is in the form of a rectangular tube extending in the front-rear direction. The front end of the tube portion  17  is open, so that the mating terminal is insertable. 
     A part of a resilient contact piece  19  provided in the tube portion  17  is shown in  FIG. 1 . Although not shown in detail, the resiliently deformable resilient contact piece  19  is disposed inside the tube portion  17 . The resilient contact piece  19  extends inward from the inner wall of the tube portion  17 . The mating terminal inserted into the tube portion  17  presses and resiliently deforms the resilient contact piece  19 . By a resilient force of the resiliently deformed resilient contact piece  19 , the mating terminal is sandwiched between the inner wall of the tube portion  17  and the resilient contact piece  19 . In this way, the mating terminal and the terminal  12  are electrically connected. 
     As shown in  FIG. 1 , the wire connecting portion  20  in the form of a rectangular tube is provided behind the tube portion  17 . The upper sandwiching portion  18 A (an example of a sandwiching portion) is provided to extend rearward in a rear end part of the upper wall of the wire connecting portion  20 , and the lower sandwiching portion  18 B (an example of the sandwiching portion) is provided to extend rearward in a rear end part of the lower wall of the wire connecting portion  20 . The upper and lower sandwiching portions  18 A,  18 B have a shape elongated in the front-rear direction. Lengths in the front-rear direction of the upper and lower sandwiching portions  18 A,  18 B are substantially equal. 
     An upper holding protrusion  23 A projecting downward is provided in a front end part of the lower surface of the upper sandwiching portion  18 A. A lower holding protrusion  23 B projecting upward is provided in a rear end part of the upper surface of the lower sandwiching portion  18 B. The upper and lower holding protrusions  23 A,  23 B are formed at positions shifted in the front-rear direction. 
     The lower surface of the upper sandwiching portion  18 A and the upper surface of the lower sandwiching portion  18 B bite into an oxide film formed on the surface of the core  13  to peel off the oxide film, whereby a metal surface of the core  13  is exposed. By the contact of this metal surface and the upper and lower sandwiching portions  18 A,  18 B, the core  13  and the terminal body  15  are electrically connected. 
     The terminal body  15  is provided with a pair of body-side side walls  30  intersecting both the upper wall provided with the upper sandwiching portion  18 A and the lower wall provided with the lower sandwiching portion  18 B. Both side edges of the upper and lower walls of the terminal body  15  are coupled by the pair of body-side side walls  30 . 
     [Slide Portion  16 ] 
     As shown in  FIG. 2 , the slide portion  16  is in the form of a rectangular tube extending in the front-rear direction. The slide portion  16  is formed by a known method such as cutting, casting or press-working if necessary. An arbitrary metal such as copper, copper alloy, aluminum, aluminum alloy or stainless steel can be appropriately selected as a metal constituting the slide portion  16  if necessary. The slide portion  16  according to this embodiment is made of stainless steel. A plating layer may be formed on the surface of the slide portion  16 . An arbitrary metal such as tin, nickel or silver can be appropriately selected as a metal constituting the plating layer if necessary. 
     A cross-section of the inner shape of a front half of the slide portion  16  is the same as or somewhat larger than that of the outer shape of a region of the terminal body  15  where the upper and lower sandwiching portions  18 A,  18 B are provided. In this way, the front half of the slide portion  16  is disposed outside the region of the terminal body  15  where the upper and lower sandwiching portions  18 A,  18 B are provided. In the following description, the front half of the slide portion  16 A may be written as a wide portion  16 A. 
     As shown in  FIG. 1 , an upper pressurizing portion  25 A (an example of a pressurizing portion) projecting downward is provided on an upper pressurizing wall  31  (an example of a pressurizing wall) constituting the upper wall of the slide portion  16 . A lower pressurizing portion  25 B (an example of the pressurizing portion) projecting upward is provided on a lower pressurizing wall  32  (an example of the pressurizing wall) constituting the lower wall of the slide portion  16 . A part of the slide portion  16  where the upper and lower pressurizing portions  25 A,  25 B are provided serves as a narrow portion  16 B in which a cross-section of the inner shape of the slide portion  16  is narrower than in the wide portion  16 A. 
     The slide portion  16  is formed with a pair of slide-side side walls  33  intersecting the upper and lower pressurizing walls  31 ,  32 . Both side edges of the upper and lower pressurizing walls  31 ,  32  are coupled by the pair of slide-side side walls  33 . 
     As shown in  FIG. 1 , a partial lock receiving portion  26  is open at a position near a front end part in the slide-side side wall  33  of the slide portion  16 . Further, a full lock receiving portion  27  is open at a position behind the partial lock receiving portion  26  in the slide-side side wall  33  of the slide portion  16 . The partial lock receiving portion  26  and the full lock receiving portion  27  are resiliently lockable to a locking projection  28  provided on the side wall of the terminal body  15 . 
     As shown in  FIG. 1 , with the locking projection  28  of the terminal body  15  and the partial lock receiving portion  26  of the slide portion  16  locked, the slide portion  16  is held at a partial locking position with respect to the terminal body  15 . In this state, the wide portion  16 A is located outside the upper and lower sandwiching portions  18 A,  18 B of the terminal body  15 . In a partially locked state, the upper and lower pressurizing portions  25 A,  25 B of the slide portion  16  are separated rearward from the rear end edges of the upper and lower sandwiching portions  18 A,  18 B of the terminal body  15 . 
     With the locking projection  28  of the terminal body  15  and the full lock receiving portion  27  of the slide portion  16  locked, the slide portion  16  is held at a full locking position with respect to the terminal body  15 . As shown in  FIG. 9 , in this state, the narrow portion  16 B is located outside the upper and lower sandwiching portions  18 A,  18 B of the terminal body  15 . In a fully locked state, the upper pressurizing portion  25 A of the slide portion  16  is in contact with the upper sandwiching portion  18 A from above the upper sandwiching portion  18 A. Further, the lower pressurizing portion  25 B of the slide portion  16  is in contact with the lower sandwiching portion  18 B from below the lower sandwiching portion  18 B. 
     As described above, the slide portion  16  is slidable in the front-rear direction between the partial locking position and the full locking position described above while being externally fit to the region of the terminal body  15  where the upper and lower sandwiching portions  18 A,  18 B are provided. 
     As shown in  FIG. 3 , with the slide portion  16  held at the full locking position with respect to the terminal body  15 , the upper pressurizing portion  25 A presses the upper sandwiching portion  18 A from above, thereby deforming the upper sandwiching portion  18 A downward. Further, the lower pressurizing portion  25 B presses the lower sandwiching portion  18 B from below, thereby deforming the lower sandwiching portion  18 B upward. In this way, with the core  13  extending in the front-rear direction in a space between the upper and lower sandwiching portions  18 A,  18 B and the slide portion  16  held at the full locking position with respect to the terminal body  15 , the core  13  is vertically sandwiched by the resiliently deformed upper and lower sandwiching portions  18 A,  18 B. That is, the upper sandwiching portion  18 A contacts the core  13  from above by being pressed downward by the upper pressurizing portion  25 A, and the lower sandwiching portion  18 B contacts the core  13  from below by being pressed upward by the lower pressurizing portion  25 B. Since the upper pressurizing portion  25 A presses the upper sandwiching portion  18 A downward from above, a direction from up to down is a pressing direction. Since the lower pressurizing portion  25 B presses the lower sandwiching portion  18 AB upward from below, a direction from down to up is a pressing direction. 
     As shown in  FIG. 3 , with the slide portion  16  held at the full locking position with respect to the terminal body  15 , the upper holding protrusion  23 A of the upper sandwiching portion  18 A presses the core  13  from above and the lower holding protrusion  23 B of the lower sandwiching portion  18 B presses the core  13  from below. In this way, the core  13  is pressed by the upper and lower holding protrusion  23 A,  23 B, thereby being held in a state bent in the vertical direction. The core  13  and the terminal  12  are electrically connected also by the upper and lower holding protrusions  23 A,  23 B. 
     As shown in  FIG. 5 , a jig contact portion  46  projecting upward from the upper pressurizing wall  31  is provided in a front end part of the slide portion  16 . By bringing a jig  45  into contact with the jig contact portion  46  from behind and pushing the slide portion  16  forward (direction indicated by an arrow A) by this jig  45 , the slide portion  16  is movable forward. Note that the jig  45  is relatively smaller in scale as compared to dies and a facility for operating these dies. Thus, a cost increase due to the jig  45  is suppressed. 
     As shown in  FIGS. 1 and 2 , a pair of guiding portions  47  projecting inwardly of the slide portion  16  are provided at positions near a rear end part of the slide portion  16  on both left and right slide-side side walls  33 . The guiding portions  47  are formed to become narrower from a rear side toward a front side. The core  13  slides in contact with the inner surfaces of the guiding portions  47 , thereby being guided into the slide portion  16 . 
     [Restricting Portion  50 ] 
     As shown in  FIG. 1 , the left and right slide-side side walls  33  are formed with restricting portions  50  projecting inwardly of the slide portion  16 . The restricting portions  50  are formed at positions near the top of the slide portion  16  and somewhat forward of the upper pressurizing portion  25 A. 
     The restricting portion  50  is formed by press-working the slide-side side wall  33 . As shown in  FIG. 4 , the restricting portion  50  has a substantially trapezoidal shape when viewed laterally. The upper and lower surfaces of the restricting portion  50  are formed to be parallel in the front-rear direction. Parallel means not only a case where things are parallel, but also a case where things are not parallel, but can be recognized to be substantially parallel. An interval between the upper surface of the restricting portion  50  and the upper pressurizing wall  31  is set to be larger than a vertical thickness of the tip of the upper sandwiching portion  18 A. 
     The front surface of the restricting portion  50  is formed to extend in the vertical direction. A corner on an upper end part of the front surface of the restricting portion  50  is chamfered. In this way, a front inclined portion  51  formed to widen the interval between the restricting portion  50  and the upper pressurizing wall  31  toward the front side is formed on a front side of the restricting portion  50 . The tip of the upper sandwiching portion  18 A slides in contact with the front inclined portion  51 , whereby the tip of the upper sandwiching portion  18 A is guided between the upper surface of the restricting portion  50  and the upper pressurizing wall  31 . 
     A rear inclined portion  52  inclined downward toward the rear side is formed in a rear part of the restricting portion  50 . The front surface of the upper pressurizing portion  25 A is formed to be obliquely inclined downward to a lower-rear side. An interval between the rear inclined portion  52  of the restricting portion  50  and the front surface of the upper pressurizing portion  25 A is formed to be widened toward the rear side. 
     [Connection Process of Wire  11 ] 
     Next, an example of a connection process of the wire  11  and the terminal  12  is described. The connection process of the wire  11  and the terminal  12  is not limited to the one described below. 
     The terminal body  15  and the slide portion  16  are formed by a known method. The slide portion  16  is assembled with the terminal body  15  from behind. The front end edge of the slide portion  16  comes into contact with the locking projection  28  of the terminal body  15  from behind and the slide-side side wall  33  of the slide portion  16  is expanded and deformed. If the slide portion  16  is further pushed forward, the slide-side side wall  33  is restored and the partial lock receiving portion  26  of the slide portion  16  is locked to the locking projection  28  of the terminal body  15 . In this way, the slide portion  16  is held at the partial locking position with respect to the terminal body  15 . The wide portion  16 A is located outside the upper and lower sandwiching portions  18 A,  18 B. Further, the tip of the upper sandwiching portion  18 A slides in contact with the front inclined portions  51  of the restricting portions  50 , thereby being inserted between the upper surfaces of the restricting portions  50  and the upper pressurizing wall  31 . 
     The core  13  of the wire  11  is exposed by stripping the insulation coating  14  by a known method. 
     As shown in  FIGS. 5 and 6 , the core  13  is inserted from behind into the terminal  12  in which the terminal body  15  and the slide portion  16  are partially locked. The core  13  comes into contact with the guiding portions  47  of the slide portion  16 , thereby being guided into the slide portion  16 . If the wire  11  is further pushed forward, a front end part of the core  13  enters the terminal body  15  and reaches the space between the upper and lower sandwiching portions  18 A,  18 B. 
     Subsequently, as shown in  FIG. 5 , the slide portion  16  is slid forward by bringing the jig  45  into contact with the jig contact portion  46  from behind. The slide portion  16  is relatively moved forward with respect to the terminal body  15 . At this time, locking between the locking projection  28  of the terminal body  15  and the partial lock receiving portion  26  of the slide portion  16  is released and the side wall of the slide portion  16  rides on the locking projection  28  to be expanded and deformed. 
     As shown in  FIG. 7 , the tip of the upper sandwiching portion  18 A enters between the upper pressurizing portion  25 A and the rear inclined portions  52  to be bent downward. At this time, since the restricting portions  50  are disposed below the upper sandwiching portion  18 A, downward excessive deflection of the upper sandwiching portion  18 A is suppressed. 
     If the slide portion  16  is moved forward, the slide-side side wall  33  is restored and the locking projection  28  of the terminal body  15  and the full lock receiving portion  27  of the slide portion  16  are resiliently locked. In this way, the slide portion  16  is held at the full locking position with respect to the terminal body  15 . In this state, the narrow portion  16 B is located outside the upper and lower sandwiching portions  18 A,  18 B. 
     As shown in  FIG. 3 , with the slide portion  16  held at the full locking position with respect to the terminal body  15 , the upper pressurizing portion  25 A of the slide portion  16  comes into contact with the upper sandwiching portion  18 A of the terminal body  15  from above to press the upper sandwiching portion  18 A downward. Further, the lower pressurizing portion  25 B of the slide portion  16  comes into contact with the lower sandwiching portion  18 B of the terminal body  15  from below to press the lower sandwiching portion  18 B upward. 
     As shown in  FIG. 3 , the core  13  is sandwiched by the lower surface of the upper sandwiching portion  18 A and the upper surface of the lower sandwiching portion  18 B, whereby the oxide film formed on the surface of the core  13  is peeled off to expose the metal surface constituting the core  13 . By the contact of this metal surface with the upper and lower sandwiching portions  18 A,  18 B, the wire  11  and the terminal  12  are electrically connected. 
     With the core  13  sandwiched from upper and lower sides by the upper and lower sandwiching portions  18 A,  18 B, the core  13  is sandwiched by the upper holding protrusion  23 A of the upper sandwiching portion  18 A and the lower holding protrusion  23 B of the lower sandwiching portion  18 B, thereby being held in the state extending in the front-rear direction and bent in the vertical direction. Since the core  13  can be firmly held in this way, a holding force of the wire  11  and the terminal  12  can be enhanced when a pulling force is applied to the wire  11 . 
     Functions and Effects of Embodiment 
     Next, functions and effects of this embodiment are described. This embodiment relates to the terminal  12  to be connected to the wire  11  and including the terminal body  15  having the upper and lower sandwiching portions  18 A,  18 B for sandwiching the wire  11 , and the tubular slide portion  16  for accommodating the terminal body  15  inside, wherein the slide portion  16  includes the wide portion  16 A located on the front side in the sliding direction of the slide portion  16  and the narrow portion  16 B located behind the wide portion  16 A in the sliding direction, the inner shape of the slide portion  16  being narrower in the narrow portion  16 B than in the wide portion  16 A, the narrow portion  16 B is provided with the upper and lower pressurizing portions  25 A,  25 B projecting inwardly of the slide portion  16 , the upper pressurizing portion  25 A presses the upper sandwiching portion  18 A toward the core  13  of the wire  11  with the slide portion  16  slid in the sliding direction with respect to the terminal body  15  and the narrow portion  16 B located outside the upper and lower sandwiching portions  18 A,  18 B, and the slide portion  16  is provided with the restricting portions  50  for restricting the bending of the upper sandwiching portion  18 A on a side forward of the upper pressurizing portion  25 A in the sliding direction. 
     Further, this embodiment relates to the wire with terminal  10  including the wire  11  and the terminal  12  connected to the wire  11 . 
     Since the restricting portions  50  are provided on the side forward of the upper pressurizing portion  25 A in the sliding direction of the slide portion  16 , it can be suppressed that the upper sandwiching portion  18 A is bent by contacting the upper pressurizing portion  25 A in a state before the narrow portion  16 B slides to the outside of the upper sandwiching portion  18 A. 
     According to this embodiment, the slide portion  16  is so assembled with the terminal body  15  as to be movable between the full locking position where the upper and lower pressurizing portions  25 A,  25 B are in contact with the upper and lower sandwiching portions  18 A,  18 B and the partial locking position where the upper and lower pressurizing portions  25 A,  25 B are separated from the upper and lower sandwiching portions  18 A,  18 B, and the bending of the upper sandwiching portion  18 A is restricted by the restricting portions  50  with the slide portion  16  disposed at the partial locking position. 
     With the slide portion  16  assembled at the partial locking position with the terminal body  15 , even if the terminal body  15  and the slide portion  16  rattle due to vibration or the like, unintended bending of the upper sandwiching portion  18 A is suppressed by the restricting portions  50 . 
     According to this embodiment, the slide portion  16  includes the upper pressurizing wall  31  provided with the upper pressurizing portion  25 A and the slide-side side walls  33  intersecting the upper pressurizing wall  31 , the restricting portions  50  project inwardly of the slide portion  16  from the inner surfaces of the slide-side side walls  33 , and the upper sandwiching portion  18 A passes between the upper pressurizing wall  31  and the restricting portions  50  when the slide portion  16  slides. 
     In this way, unintended bending of the upper sandwiching portion  18 A can be suppressed when the slide portion  16  slides. 
     According to this embodiment, the slide portion  16  includes the upper pressurizing wall  31  provided with the upper pressurizing portion  25 A and the slide-side side walls  33  intersecting the upper pressurizing wall  31 , and the front inclined portions  51  formed to widen the intervals between the restricting portions  50  and the upper pressurizing wall  31  toward the front side in the sliding direction are provided on the front sides in the sliding direction of the restricting portions  50 . 
     The upper sandwiching portion  18 A slides in contact with the front inclined portions  51 , whereby the upper sandwiching portion  18 A is guided between the restricting portions  50  and the upper pressurizing wall  31 . In this way, unintended bending of the upper sandwiching portion  18 A can be suppressed. 
     According to this embodiment, the rear inclined portions  52  inclined in a pressurizing direction of the upper pressurizing portion  25 A to press the upper sandwiching portion  18 A toward the rear side in the sliding direction are provided on the rear sides in the sliding direction of the restricting portions  50 . 
     The upper sandwiching portion  18 A is bent along the rear inclined portions  52 , whereby a bending direction of the upper sandwiching portion  18 A can be so controlled that the upper sandwiching portion  18 A is bent in the pressurizing direction toward the rear side in the sliding direction. In this way, the bending of the upper sandwiching portion  18 A in an unintended direction can be suppressed. 
     Second Embodiment 
     Next, a second embodiment of the present disclosure is described with reference to  FIGS. 8 and 9 . As shown in  FIGS. 8 and 9 , restricting portions  60  according to this embodiment have a cylindrical shape and project from left and right slide-side side walls  33  of a slide portion  66 . 
     A semi-circular surface formed on the front surface of the restricting portion  60  serves as a front inclined portion  61  for guiding an upper sandwiching portion  18 A between the restricting portion  60  and an upper pressurizing wall  31  by sliding in contact with the upper sandwiching portion  18 A. 
     A semi-circular surface formed on the rear surface of the restricting portion  60  serves as a rear inclined portion  62  inclined downward toward a rear side. 
     Since the configuration other than the above is substantially the same as in the first embodiment, the same members are denoted by the same reference signs and repeated description is omitted. 
     Since the restricting portion  60  according to this embodiment has a cylindrical shape, the restricting portion  60  is easily formed by press-working. 
     Further, since the front inclined portions  61  formed on the front surfaces of the restricting portions  60  are semi-circular surfaces, the upper sandwiching portion  18 A is easily guided between the restricting portions  60  and the upper pressurizing wall  31 . In this way, unintended bending of the upper sandwiching portion  18 A can be suppressed. 
     Further, since the rear inclined portions  62  formed on the rear surfaces of the restricting portions  60  are semi-circular surfaces, the upper sandwiching portion  18 A is easily guided between the restricting portions  60  and an upper pressurizing portion  25 A. In this way, unintended bending of the upper sandwiching portion  18 A can be suppressed. 
     Third Embodiment 
     Next, a third embodiment of the present disclosure is described with reference to  FIGS. 10 to 12 . A terminal body  75  according to this embodiment is formed by press-working one metal plate material. As shown in  FIG. 10 , a first easily bendable portion  70  cut rightward from the left side edge of an upper sandwiching portion  78 A is formed in a front end part of the upper sandwiching portion  78 A according to this embodiment. A second easily bendable portion  71  cut leftward is formed at a position behind the first easily bendable portion  70  on the right side edge of the upper sandwiching portion  78 A. The first and second easily bendable portions  70 ,  71  are formed to be narrower than other parts of the upper sandwiching portion  78 A. In this way, the first and second easily bendable portions  70 ,  71  are easily bent as compared to the other parts of the upper sandwiching portion  78 A when being pressed downward by an upper pressurizing portion  25 A. 
     As shown in  FIG. 11 , a projection  73  is formed to project downward on the upper sandwiching portion  78 A. The projection  73  extends along the front-rear direction. The shape of the projection  73  is not limited and may be, for example, an oval shape when viewed from above. 
     As shown in  FIG. 12 , a front end part of the projection  73  is formed at a position behind the first easily bendable portion  70  and in front of the second easily bendable portion  71 . A rear end part of the projection  73  is formed at a position behind the second easily bendable portion  71 . In this way, the projection  73  is formed to cross the second easily bendable portion  71  in the front-rear direction. 
     An excessive deflection suppressing portion  76  for suppressing excessive deflection when the upper sandwiching portion  78 A is deformed downward is provided below the left side edge of the upper sandwiching portion  78 A, out of the terminal body  75 . The excessive deflection suppressing portion  76  is formed as a slope inclined downward toward a rear side on the upper surface of the left side wall of the terminal body  75 . 
     Since the configuration other than the above is substantially the same as in the first embodiment, the same members are denoted by the same reference signs and repeated description is omitted. 
     According to this embodiment, the upper sandwiching portion  78 A extends along the front-rear direction and is provided with the projection  73  projecting downward. 
     Since the strength of the upper sandwiching portion  78 A is improved by providing the projection  73 , unintended deformation of the upper sandwiching portion  78 A is suppressed. 
     The upper sandwiching portion  78 A is provided with the second easily bendable portion  71  formed to be narrower than the other parts and the projection  73  is formed to cross the second easily bendable portion  71 . 
     To reliably sandwich the wire  11  by the upper sandwiching portion  78 A, the upper sandwiching portion  78 A is preferably bent at a predetermined position. Accordingly, it is considered to reliably bend the upper sandwiching portion  78 A at the predetermined position by providing the second easily bendable portion  71  at a position behind the first easily bendable portion  70 . By forming easily bendable parts of the upper sandwiching portion  78 A separated in the front-rear direction, the upper sandwiching portion  78 A can be gently bent. 
     On the other hand, by providing the first and second easily bendable portions  70 ,  71 , the first or second easily bendable portion  70 ,  71  may be buckled at an unintended timing due to vibration or the like. Particularly, the second easily bendable portion  71  formed behind the first easily bendable portion  70  is easily buckled since being closer to the tip of the upper sandwiching portion  78 A. Accordingly, by forming the projection  73  to cross the second easily bendable portion  71 , the strength of the second easily bendable portion  71  can be adjusted. In this way, the buckling of the second easily bendable portion  71  at an unintended timing can be suppressed. 
     Fourth Embodiment 
     Next, a fourth embodiment of the present disclosure is described with reference to  FIGS. 13 to 15 . As shown in  FIG. 13 , a terminal  82  includes a terminal body  85  and a slide portion  86 . A wire connecting portion  90  includes a pair of body-side side walls  91  intersecting an upper wall  93  provided with an upper sandwiching portion  18 A and a lower wall provided with a lower sandwiching portion  18 B. Engaging projections  87  projecting outward are formed at positions above a locking projection  28  on the body-side side walls  91  of the wire connecting portion  90 . The engaging projections  87  are in the form of ribs elongated in the front-rear direction. Front and rear end parts of the engaging projections  87  are formed into a curved surface shape. 
     As shown in  FIGS. 13 and 14 , slide-side side walls  92  of the slide portion  86  are formed with engaging recesses  88 , into which the engaging projections  87  are accommodated, at positions corresponding to the engaging projections  87  of the wire connecting portion  90  with the slide portion  86  externally fit to the wire connecting portion  90 . The engaging recesses  88  extend in the front-rear direction. Front end parts of the engaging recesses  88  are open forward. The engaging recesses  88  do not penetrate through the slide-side side walls  92  of the slide portion  86 . The engaging recesses  88  have a rectangular cross-sectional shape. 
     A vertical height of the engaging projections  87  is equal to or somewhat smaller than a vertical width of the engaging recesses  88 . In this way, the engaging projections  87  are accommodated into the engaging recesses  88  in such a state movable in the front-rear direction in the engaging recesses  88 . 
     A length in the front-rear direction of the engaging recesses  88  is so set that rear end parts of the engaging projections  87  do not interfere with the engaging recesses  88  with the slide portion  86  held at full locking position with respect to the terminal body  85 . 
     Since the configuration other than the above is substantially the same as in the first embodiment, the same members are denoted by the same reference signs and repeated description is omitted. 
     According to this embodiment, the terminal body  85  includes the body-side side walls  91  intersecting the upper wall  93  provided with the upper sandwiching portion  18 A and the lower wall  94  provided with the lower sandwiching portion  18 B, the slide portion  86  includes the slide-side side walls  92  intersecting an upper pressurizing wall  31  provided with an upper pressurizing portion  25 A and a lower pressurizing wall  32  provided with a lower pressurizing portion  25 B, the body-side side walls  91  include the engaging projections  87  projecting toward the slide-side side walls  92 , the slide-side side walls  92  include the engaging recesses  88 , into which the engaging projections  87  are accommodated, at the positions corresponding to the engaging projections  87 , and both the engaging projections  87  and the engaging recesses  88  extend along the front-rear direction. 
     The engaging projections  87  accommodated into the engaging recesses  88  contact the inner walls of the engaging recesses  88 , whereby relative position shifts of the terminal body  85  and the slide portion  86  are suppressed. In this way, the rattling of the terminal body  85  and the slide portion  86  by receiving vibration or the like can be suppressed. Specifically, upper and lower end parts of the engaging projections  87  respectively contact upper and lower parts of the inner walls of the engaging recesses  88 , whereby position shifts of the terminal body  85  and the slide portion  86  in the vertical direction are suppressed. Further, left and right end parts of the engaging projections  87  respectively contact left and right end parts of the inner walls of the engaging recesses  88 , whereby position shifts of the terminal body  85  and the slide portion  86  in the lateral direction are suppressed. 
     Further, since the engaging projections  87  and the engaging recesses  88  extend along the front-rear direction, the slide portion  86  can smoothly move along the front-rear direction.
