     DETAILED DESCRIPTION TO EXECUTE THE INVENTION 
     Description of Embodiments of Present Disclosure 
     First, embodiments of the present disclosure will be listed and described below. 
     (1) A wire cover-equipped connector according to the present disclosure is a wire cover-equipped connector including: a housing including a wire lead-out surface; and a wire cover configured to be disposed on the housing so as to cover the wire lead-out surface, wherein the housing includes a slide-receiving portion at a position in line with the wire lead-out surface, the wire cover includes a slide portion configured to slide against the slide-receiving portion, and a wire escape space formed so as to be separated from the slide-receiving portion, and the slide portion includes, in a front end thereof in a sliding direction of sliding against the slide-receiving portion, a wire guiding portion inclined in a direction opposite to the sliding direction while extending toward the wire escape space. With such a configuration, when the wire cover is being attached to the housing, a wire located forward of the slide portion of the wire cover is guided to the wire escape space by the wire guiding portion formed so as to be separated from the slide-receiving portion. Accordingly, when the wire cover is being attached, the wire can be prevented from being caught on the wire cover. 
     (2) The slide-receiving portion may be a wall provided at a position where the slide-receiving portion overlaps the slide portion in an inner/outer direction of the wire cover. With this configuration, when the wire cover is being attached, a wire that has come in contact with the wire guiding portion moves along the incline of the wire guiding portion and into the wire escape space, and thus the wire is prevented from being pinched between the slide-receiving portion and the slide portion. 
     (3) It is preferable that the slide-receiving portion protrudes in a lead-out direction in which the wire is lead out from the wire lead-out surface, and the wire escape space is formed at a position shifted in the lead-out direction of the wire relative to a protruding end of the slide-receiving portion. With this configuration, the wire is moved to a position shifted away from the slide-receiving portion, and thus the wire can be prevented from being pinched between the wire cover and the housing. 
     (4) It is preferable that the slide portion includes, in the front end thereof in the sliding direction, an escape recess that is recessed rearward in the sliding direction. With this configuration, the wire is moved to the escape recess formed in the front end of the slide portion, and thus the wire can be prevented from being pinched between the slide portion and the slide-receiving portion. 
     (5) It is preferable that the-receiving portion includes an inclined second guiding portion inclined inward in the wire cover while extending forward in the sliding direction. With this configuration, when a wire comes in contact with the second guiding portion provided in the slide-receiving portion, the wire is guided into the wire cover. Accordingly, when the wire cover is being attached, a wire can be prevented from being caught on the wire cover. 
     Detailed Description of Embodiment of the Present Disclosure 
     Specific examples of a wire cover-equipped connector C of the present disclosure will be described below with reference to the drawings. Note that the present invention is not limited to these illustrative examples, but is indicated by the claims, and all changes that come within the meaning and range of equivalency of the claims are intended to be embraced therein. 
     As shown in  FIG.  1   , the wire cover-equipped connector C includes a housing  10  and a wire cover  20 . The housing  10  has a wire lead-out surface  11  from which wires W are lead out. The wire lead-out surface  11  is provided with opening portions from which the wires W are lead out, and by leading out the wires W from these opening portions, the wires W extend out from the wire lead-out surface  11 . The wire cover  20  covers the wire lead-out surface  11  and houses the wires W therein. 
     Below, for each of the constituent members, the side on which the wire cover  20  is attached (upper side in  FIG.  1   ) is the upper side, and the side opposite to the side on which the wire cover  20  is attached (lower side in  FIG.  1   ) is the lower side. The forward side in the direction in which the wire cover  20  is moved when attaching the wire cover  20  to the housing  10  (right side in  FIG.  1   ) is the front side, and the rear side in the direction in which the wire cover  20  is moved when attaching the wire cover  20  to the housing  10  (left side in  FIG.  1   ) is the rear side. Also, in the following description, the near side in a direction orthogonal to the sheet plane of  FIG.  1    is the right side, and the far side is the left side. Note that the position of the wire cover  20  in  FIG.  1    is the position of the wire cover  20  once it has been moved and attached to the housing  10 . 
     The housing  10  is made of a synthetic resin. The housing  10  has an elongated shape in the front-rear direction. As shown in  FIG.  2   , the housing  10  is provided with terminal housing chambers  18  that each house a terminal fitting. The terminal housing chambers  18  are arranged in the front-rear direction and the left-right direction. 
     Terminal fittings are housed in the terminal housing chambers  18  from above. Each terminal fitting is connected to a terminal end of a wire W. The wires W extend out upward from the wire lead-out surface  11  of the housing  10 . A bundle of wires W are bent forward inside the wire cover  20 . 
     As shown in  FIGS.  2  to  4   , guide frames  12  are respectively provided on the left and right sides of the wire lead-out surface  11  (two sides of the wire lead-out surface  11  in a direction orthogonal to a sliding direction). The guide frames  12  protrude upward from the wire lead-out surface  11 . Each guide frame  12  is elongated in the front-rear direction. 
     As shown in  FIGS.  2  to  4   , each guide frame  12  is provided with rail portions  13 . The rail portions  13  are fitted to corresponding rail-receiving portions  25  provided in the wire cover  20  (see  FIG.  5   ). The rail portions  13  protrude outward from the upper end of each guide frame  12  (the rail portions  13  provided on the right guide frame  12  protrude rightward, and the rail portions  13  provided on the left guide frame  12  protrude leftward). 
     As shown in  FIGS.  2  to  4   , three rail portions  13  are provided spaced apart from each other in the front-rear direction. The three rail portions  13  are lined up in a straight line. Each rail portion  13  is longer in the front-rear direction than it is in the left-right direction. Among the three rail portions  13 , the front-rear lengths of the rail portion  13  disposed at the front end and the rail portion  13  disposed at the rear end are smaller than the front-rear length of the rail portion  13  provided at the center in the front-rear direction. The rail portion  13  disposed at the rear end also functions as a lock-receiving portion  14  to which a lock portion  27  of the wire cover  20  is locked. 
     As shown in  FIGS.  2  to  4   , the housing  10  has slide-receiving portions  15 . As shown in  FIG.  1   , slide portions  22  provided on the wire cover  20  slide against the slide-receiving portions  15  when the wire cover  20  is being attached. The slide-receiving portions  15  protrude upward (the lead-out direction of the wires W) from the wire lead-out surface  11 . 
     As shown in  FIGS.  2  and  3   , the slide-receiving portions  15  are provided at positions (on left and right sides) in line with the wire lead-out surface  11 . The slide-receiving portions  15  provided on the left side of the wire lead-out surface  11  are walls that protrude along the left side surface of the housing  10 . The slide-receiving portions  15  provided on the right side of the wire lead-out surface  11  are walls that protrude upward along the right side surface of the housing  10 . 
     As shown in  FIG.  3   , the slide-receiving portions  15  are located outward of the rail portions  13  (the right slide-receiving portions  15  are located rightward of the right rail portions  13 , and the left slide-receiving portions  15  are located leftward of the left rail portions  13 ). 
     As shown in  FIG.  3   , the rear surfaces of the slide-receiving portions  15  are each provided with a second guiding portion  17 . Each second guiding portion  17  is formed on an inner corner portion of the rear surface of the corresponding slide-receiving portion  15  (a corner portion on the left side of the right slide-receiving portions  15 , and a corner portion on the right side of the left slide-receiving portions  15 ). The second guiding portion  17  is an inclined surface that is inclined inward in the wire cover  20  while extending forward (forward in the moving direction of the wire cover  20 ). The second guiding portion  17  is formed extending the entire length between the upper and lower ends of the slide-receiving portion  15 . 
     As shown in  FIG.  4   , two slide-receiving portions  15  are provided spaced apart from each other in the front-rear direction, on each of the left and right sides of the housing  10 . Each slide-receiving portion  15  is longer in the front-rear direction than it is in the vertical direction. The vertical length of the slide-receiving portion  15  is equal to the vertical length of the guide frame  12 . 
     As shown in  FIG.  4   , the rear surface of each slide-receiving portion  15  is provided with an inclined surface  16  that is inclined upward while extending forward. The inclined surface  16  of the front slide-receiving portion  15  is formed extending the entire length between the upper and lower ends of the front slide-receiving portion  15 . The inclined surface  16  of the rear slide-receiving portion  15  is formed in a smaller vertical range than the inclined surface  16  of the front slide-receiving portion  15  is. A front surface  15 A of each slide-receiving portion  15  is perpendicular to the wire lead-out surface  11 . 
     The wire cover  20  is moved along the wire lead-out surface  11  and attached to the housing  10 . The wire cover  20  is made of a synthetic resin. As shown in  FIGS.  5  and  6   , the wire cover  20  has a main body portion  21  and slide portions  22 . The main body portion  21  has a cap shape that is elongated in the front-rear direction. The main body portion  21  includes a pair of left and right side surface portions  23  and an upper surface portion  24  that connects the upper ends of the pair of side surface portions  23 . The upper surface portion  24  opposes the wire lead-out surface  11  when the wire cover  20  is attached to the housing  10 . The lower face and the front face of the main body portion  21  are open. 
     When attaching the wire cover  20  to the housing  10 , the slide portions  22  are slid along the slide-receiving portions  15  of the housing  10 . As shown in  FIG.  5   , the pair of slide portions  22  are provided on the left and right sides of the wire cover  20 . The left and right slide portions  22  are symmetrical with respect to the center in the left-right direction of the wire cover  20 . 
     As shown in  FIGS.  5  and  6   , the slide portions  22  are elongated in the front-rear direction along respective bottom edges of the side surface portions  23  of the main body portion  21 . The slide portions  22  protrude inward of the side surface portions  23  (the left slide portion  22  protrudes rightward of the left side surface portion  23 , and the right slide portion  22  protrudes leftward of the right side surface portion  23 ). 
     As shown in  FIG.  5   , a sliding surface  31  is provided on the outer surface of each slide portion  22  (the right surface of the right slide portion  22  and the left surface of the left slide portion  22 ). The sliding surface  31  extends rearward from the front end of the slide portion  22 . As shown in  FIG.  7   , the sliding surfaces  31  slide along upper surfaces  15 C of the slide-receiving portions  15  of the housing  10 . 
     As shown in  FIGS.  8  and  10   , the front end of each slide portion  22  is provided with an escape recess  32 . The escape recess  32  is formed outward of the front end of the slide portion  22  (the right escape recess  32  is provided on the right side of the corresponding slide portion  22 , and the left escape recess  32  is provided on the left side of the corresponding slide portion  22 ). The escape recess  32  is provided in a region above (in the lead-out direction of the wires W) the upper surfaces (protruding ends)  15 C of the slide-receiving portions  15 . The escape recess  32  has a recessed inclined surface  32 A that is inclined outward while extending toward the rear side. The lower end of the recessed inclined surface  32 A is continuous with the front end of the sliding surface  31 . The upper end of the recessed inclined surface  32 A is continuous with a lower edge  21 A of the main body portion  21 . 
     As shown in  FIG.  5   , each slide portion  22  is provided with a rail-receiving portion  25  to which the corresponding rail portions  13  of the housing  10  are fitted. The rail-receiving portion  25  is a groove that is recessed outward from the inner surface of the slide portion  22  (the right surface of the left slide portion  22  and the left surface of the right slide portion  22 ). 
     The rail-receiving portion  25  includes an opening portion  25 A in the front surface of the slide portion  22 . The opening portion  25 A of the rail-receiving portion  25  is an access port for the rail portion  13 . The opening portion  25 A of the rail-receiving portion  25  is provided with a tapered portion  26  that guides in the rail portion  13 . The tapered portion  26  is inclined such that the size of the opening portion  25 A in the left-right and vertical directions decreases rearward. 
     As shown in  FIG.  5   , the slide portion  22  is provided with a second groove  28  that is separate from the rail-receiving portion  25 . The second groove  28  is a groove that is recessed upward from the upper surface of the rail-receiving portion  25 . The second groove  28  has an opening portion  28 A in the front surface of the slide portion  22 . The opening portion  28 A of the second groove  28  has an elongated shape in the vertical direction. The lower end of the opening portion  28 A of the second groove  28  is continuous with the inner end portion of the opening portion  25 A of the rail-receiving portion  25 . The opening portion  28 A of the second groove  28  and the opening portion  25 A of the rail-receiving portion  25  intersect each other at a right angle. 
     As shown in  FIG.  6   , the rear end portion of the slide portion  22  is provided with the lock portion  27  that locks to the lock-receiving portion  14  provided in the housing  10 . The lock portion  27  protrudes downward from the upper surface of the rail-receiving portion  25 . The lock portion  27  can be elastically displaced in the vertical direction. 
     As shown in  FIG.  6   , the rail-receiving portion  25  is provided at a position lower than the lower edge  21 A of the main body portion  21 . In a state where the wire cover  20  is attached to the housing  10 , the lower edges  21 A of the main body portion  21  extend parallel to the upper ends of the slide portions  22 . A gap larger than the outer diameter of a wire W is formed between the lower edge  21 A of the main body portion  21  and the upper end of the slide portion  22 . The gap between the lower edge  21 A of the main body portion  21  and the upper end of the slide portion  22  is open forward. 
     As shown in  FIG.  7   , the slide portion  22  includes a wire guiding portion  29  that guides a wire W located forward of the slide portion  22  into a wire escape space S. Wire escape spaces S are located forward of the front surfaces of the slide portions  22 , respectively. The wire escape spaces S are distanced from the slide-receiving portions  15  in a direction orthogonal to the wire lead-out surface  11 . Each wire escape space S is located at a position higher than the rail-receiving portion  25 . The wire escape spaces S are formed inward of the side surface portions  23  (the left wire escape space S is on the right side of the left side surface portion  23  and the right wire escape space S is on the left side of the right side surface portion  23 ). The wire escape spaces S are provided at positions shifted upward (in the lead-out direction of the wires W) from the upper surfaces  15 C of the slide-receiving portions  15 . 
     The wire guiding portion  29  is an inclined surface that is formed on the front surface of the slide portion  22 . The wire guiding portion  29  is inclined toward the wire escape space S while extending from the front end toward the rear end. In other words, the wire guiding portion  29  is inclined rearward (in a direction in which the wire cover  20  is removed from the housing  10 ) while extending from the lower end to the upper end. The wire guiding portion  29  is formed in a region inward of the escape recess  32 , in the front surface of the slide portion  22  (see  FIG.  5   ). As shown in  FIG.  8   , in a state where the wire guiding portion  29  and the inclined surface  16  of the slide-receiving portion  15  face each other in the front-rear direction, the distance between the wire guiding portion  29  and the inclined surface  16  in the front-rear direction increases upward. The wire guiding portion  29  has an incline that is the inverse of that of the inclined surface  16  of the slide-receiving portion  15 . 
     Next, an example of operations for assembling the wire cover-equipped connector C will be described. 
     First, terminal fittings are housed in the housing  10 . The terminal fittings fixed to terminal ends of the wires W are inserted into terminal housing chambers  18  from the wire lead-out surface  11  side of the housing  10 . Once the terminal fittings are housed in the terminal housing chambers  18 , the wires W enter a state where they extend from the wire lead-out surface  11 . 
     Next, the wire cover  20  is attached to the housing  10 . Specifically, first, the front end portions of the rail-receiving portions  25  of the wire cover  20  are respectively fitted to the rail portions  13  at the rear end of the housing  10  from the rear side. In doing so, as shown in  FIG.  8   , the sliding surfaces  31  of the slide portions  22  of the wire cover  20  extend along the upper surfaces  15 C of the slide-receiving portions  15  of the housing  10 . Also, as shown in  FIG.  9   , outer side surfaces  22 A of the slide portions  22  of the wire cover  20  extend along inner side surfaces  15 B of the slide-receiving portions  15  of the housing  10 . Specifically, the left side surface of the right slide-receiving portion  15  extends along the right side surface of the right slide portion  22 , and the right side surface of the left slide-receiving portion  15  extends along the left side surface of the left slide portion  22 . 
     Next, the wire cover  20  is moved forward. The wire cover  20  is guided in a straight line due to the rail portions  13  being fitted to the rail-receiving portions  25 . The bundle of electric wires W are bent inward in the main body portion  21  along with the movement of the wire cover  20 . At this time, there are cases where a wire W may extend out from the main body portion  21  (on the left or right side of the main body portion  21 ). As shown in  FIG.  8   , the wire W extending out from the main body portion  21  comes in contact with the wire guiding portion  29  of the slide portion  22 , and is moved to the wire escape space S as the wire cover  20  moves forward. Here, before the wire W is completely moved to the wire escape space S, the distance in the front-rear direction between the wire guiding portion  29  and the inclined surface  16  may become smaller than the outer diameter of the wire W. In this case, the wire W can escape to the escape recess  32  formed in the front end of the slide portion  22 . Accordingly, the wire W can be prevented from being pinched between the wire guiding portion  29  and the inclined surface  16 . In this manner, the wire W is guided to a position above the upper end of the slide-receiving portion  15  so as to not become pinched between the wire guiding portion  29  and the inclined surface  16 . Also, the wire W comes in contact with the second guiding portion  17  of the slide-receiving portion  15  and is guided into the main body portion  21 . Here, even if the wire W is not entirely positioned inside the main body portion  21 , the wire W can be prevented from being pinched between the slide portion  22  and the slide-receiving portion  15 , as a result of being positioned between the lower end  21 A of the main body portion  21  and the upper surface  15 C of the slide-receiving portion  15 . 
     Ultimately, the wire cover  20  reaches the correct attachment position, and the lock portions  27  lock to the lock-receiving portions  14 , respectively. With the above, the operations for assembling the wire cover-equipped connector C are completed. 
     Next, operation and effects of the wire cover-equipped connector C with the aforementioned configuration will be described. 
     The wire cover-equipped connector C includes the housing  10  and the wire cover  20 . The housing  10  has the wire lead-out surface  11 . The wire cover  20  is disposed on the housing  10  so as to cover the wire lead-out surface  11 . The housing  10  has the slide-receiving portions  15  that are provided at positions in line with the wire lead-out surface  11 . The wire cover  20  has the slide portions  22  that slide against the slide-receiving portions  15 , and the wire escape spaces S formed so as to be separated from the slide-receiving portions  15 . Each slide portion  22  has, in the front end thereof in the sliding direction of sliding against the slide-receiving portions  15 , the wire guiding portion  29  that is inclined rearward (opposite to the sliding direction) while extending toward the wire escape space S. 
     With this configuration, when the wire cover  20  is attached to the housing  10 , a wire W located forward of the slide portion  22  of the wire cover  20  is guided away from the slide-receiving portion  15  by the wire guiding portion  29 . Accordingly, when attaching the wire cover  20 , the wire W can be prevented from being caught on the slide portion  22  of the wire cover  20 . 
     The slide-receiving portions  15  are walls provided at positions where they overlap the slide portions  22  from the outside. With this configuration, when attaching the wire cover  20 , a wire W that comes in contact with the wire guiding portion  29  moves along the incline of the wire guiding portion  29  and into the wire escape space S, and thus the wire W is prevented from being pinched between the slide-receiving portion  15  and the slide portion  22 . 
     The slide-receiving portions  15  protrude in the lead-out direction of the wires W, from the wire lead-out surface  11 . The wire escape spaces S are formed at positions shifted upward from the upper surfaces  15 C of the slide-receiving portions  15 . With this configuration, a wire W is moved to a position shifted away from the slide-receiving portions  15 , and thus the wire W can be prevented from being pinched between the wire cover  20  and the housing  10 . 
     The front end of each slide portion  22  is provided with the escape recess  32  that is recessed rearward. With this configuration, a wire W is moved into the escape recess  32  in the front end of the slide portion  22 , and the wire W can be prevented from being pinched between the slide portion  22  and the slide-receiving portion  15 . 
     Each slide-receiving portion  15  has an inclined second guiding portion  17  that is inclined inward in the wire cover  20  while extending forward in the sliding direction. With this configuration, if a wire W comes in contact with the second guiding portion  17  provided on the slide-receiving portion  15 , the wire W is guided inward in the wire cover  20 . Thus, when the wire cover  20  is being attached, the wire W can be prevented from being caught on the slide portion  22  of the wire cover  20 .
