[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-152003 Summary of the Invention [Problem to be solved by the invention]

[0004] The wiring material cover described in Patent Document 1 can accommodate the wiring material pulled out from the housing and bend the wiring material in the wiring direction, but the wiring material generates a reaction force against bending.

[0006] In order to achieve the above-mentioned object, the connector of the present invention is characterized by comprising a housing that accommodates and holds terminals connected to the ends of conductive wiring material, and from whose ends the wiring material is pulled out, a protective cover that is assembled to the end of the housing and through which the wiring material pulled out from the housing is inserted in a state bent from the pulling direction, and a wiring material straightening part that is arranged inside the protective cover and holds the wiring material, thereby maintaining the bent shape of the wiring material. [Effects of the Invention]

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these embodiments. Furthermore, the components in the following embodiments include those that are easily replaceable by those skilled in the art, or those that are substantially the same.

[0010] For ease of explanation, Figs. 4 and 5 omit illustration of terminals connected to the ends of the wiring material, housings that accommodate and hold the terminals, and the like.

[0011] [First embodiment] 1 and 2, the connector 1 according to this embodiment is mounted on a vehicle equipped with a battery, such as an electric vehicle (EV) or a hybrid electric vehicle (HEV), and is a connection mechanism that is attached to the vehicle body and electrically connected to a power source outside the vehicle through an opening on the vehicle side, thereby enabling charging of the battery. The connector 1 constitutes a so-called charging inlet, and is fitted with a cover (not shown) that can be opened and closed, exposing the connection portion to the outside of the vehicle when the cover is open.

[0012] The connector 1 includes a housing 100 that holds a terminal T connected to an end of a wiring material W such as an electric wire, a protective cover 200 that is assembled to the housing 100 and through which the wiring material W drawn out from the housing 100 is inserted while being bent from the drawing direction, and a wiring material straightening component 300 that is disposed inside the protective cover 200. The connector 1 of this embodiment realizes a configuration that allows the wiring material W to be properly routed by correcting the routing path of the wiring material W that is inserted into the protective cover 200 with the wiring material straightening component 300. Each component of the connector 1 will be described in detail below with reference to FIGS. 1 to 6.

[0013] In the following description, of the first, second, and third directions that intersect with one another, the first direction will be referred to as the "lengthwise direction X," the second direction will be referred to as the "widthwise direction Y," and the third direction will be referred to as the "heightwise direction Z." The lengthwise direction X, widthwise direction Y, and heightwise direction Z are perpendicular to one another. The X direction typically corresponds to the direction in which the wiring material W is pulled out from the housing 100, and the Y direction typically corresponds to the bending direction of the wiring material W pulled out in the lengthwise direction X (see FIG. 2). Unless otherwise specified, the directions used in the following description will be described as directions when the parts of the connector 1 are assembled.

[0014] In addition, the tip side in the length direction X typically corresponds to the side of the mating connector when the connector 1 is mated with the mating connector on the power source side, and the base side in the length direction X typically corresponds to the side of the connector 1 when the connector 1 is mated with the mating connector.

[0015] The wiring material W is, for example, an insulated electric wire in which a core wire made of a bundle of conductive metal wires is covered with an insulating sheath. As shown in FIGS. 4 to 6 , the wiring material W of this embodiment is configured to include wiring materials with different outer diameters. Specifically, it is configured to include nine wiring materials consisting of three large-diameter wiring materials WA (corresponding to the first wiring material) and six small-diameter wiring materials WB (corresponding to the second wiring material). Terminals T are connected to the terminals of the three large-diameter wiring materials WA and two of the six small-diameter wiring materials WB, respectively. The large-diameter wiring material WA is used as a power line for charging or a ground line, and the small-diameter wiring material WB is used as a communication line. The large-diameter wiring material WA here is a wiring material with a relatively large outer diameter and is thicker than the small-diameter wiring materials WB. In addition, the small diameter wiring material WB is a wiring material having a relatively small outer diameter, and is a wiring material thinner than the large diameter wiring material WA.

[0016] The terminal T is formed of a conductive metal material such as copper, and is electrically connected to a mating terminal when the connector 1 and the mating connector are mated. As shown in FIG. 2 , the terminal T of this embodiment has an electrical connection portion T1 and a wiring material connection portion T2. ​​The electrical connection portion T1 is located at the distal end in the longitudinal direction X and is connected to the mating terminal when the connector 1 is mated with the mating connector. The wiring material connection portion T2 is located at the proximal end in the longitudinal direction X and is connected to an end of the wiring material W. The shape of the terminal T is not particularly limited to the shapes shown in FIGS. 1 and 2 . The wiring material connection portion T2 may be connected to the conductor portion of the wiring material W by being crimped and crimped to the core wire, which is the conductor portion of the wiring material W, or may be connected to the conductor portion by welding or other methods.

[0017] The housing 100 is made of an insulating synthetic resin material and accommodates and holds the terminals T. As shown in FIGS. 1 and 2, the housing 100 of this embodiment includes a housing main body 110 and a rear holder 120 that is assembled to the housing main body 110.

[0018] As shown in FIGS. 1 and 2 , the housing main body 110 has a terminal accommodating portion 111, a flange portion 112, and a connecting portion 113. The terminal accommodating portion 111 is formed in a substantially cylindrical shape along the longitudinal direction X, and is a portion that accommodates the electrical connection portion T1 of the terminal T therein and is capable of holding the electrical connection portion T1. The flange portion 112 is formed to protrude from the outer surface side of the terminal accommodating portion 111, and is formed in a substantially rectangular shape along a plane (a plane extending along the width direction Y and the height direction Z) that is perpendicular to the longitudinal direction X. The connecting portion 113 is formed in communication with the terminal accommodating portion 111, and is formed in a substantially cylindrical shape along the longitudinal direction X like the terminal accommodating portion 111, and is a portion that accommodates an end of the rear holder 120 therein.

[0019] As shown in FIGS. 1 and 2 , the rear holder 120 has a main body portion 121, a connecting portion 122, and a locking frame portion 123 (see FIG. 1 ). The main body portion 121 is formed in a substantially cylindrical shape along the longitudinal direction X and is a portion that houses the wiring material connecting portion T2 of the terminal T inside and is capable of holding the wiring material connecting portion T2. ​​The connecting portion 122 is formed to protrude from the outer surface side of the main body portion 121 and is connected to the housing main body 110 by inserting the connecting portion 113 of the housing main body 110 between the main body portion 121 and the connecting portion 122. The locking frame portion 123 is formed to protrude from the outer surface side of the connecting portion 122 and is connected to the protective cover 200 by locking a locking protrusion 230 of the protective cover 200. The rear holder 120 of this embodiment is assembled with the main body portion 121 inserted into the connecting portion 113 of the housing main body 110. Therefore, the wiring material connection portion T2 of the terminal T held by the main body portion 121 of the rear holder 120 is disposed inside the connection portion 113 of the housing main body 110 (see FIG. 2).

[0020] The protective cover 200 is made of an insulating synthetic resin material and accommodates the wiring material W pulled out from the rear holder 120. As shown in FIGS. 1 and 2, the protective cover 200 of this embodiment is formed into a substantially L-shaped cylindrical shape by combining a first main body portion 200a formed into a cylindrical shape along the longitudinal direction X and a second main body portion 200b formed into a cylindrical shape along the width direction Y intersecting the longitudinal direction X. As shown in FIGS. 1 and 2, the protective cover 200 has an accommodation space portion 200S (see FIG. 2) as an internal space portion, an insertion opening 210P opening in the longitudinal direction X, an insertion opening 210Q opening in the width direction Y, a slit 220 formed from the insertion opening 210P to the insertion opening 210Q, and a locking protrusion portion 230 (see FIG. 1).

[0021] The storage space 200S is a portion partitioned and formed by the wall of the protective cover 200. The protective cover 200 can store the wiring material W by inserting the wiring material W into the storage space 200S through the insertion openings 210P and 210Q.

[0022] The insertion openings 210P and 210Q are sections defined and formed by the ends of the protective cover 200. Note that the ends of the protective cover 200 referred to here refer to the edge portions of the protective cover 200.

[0023] The slit 220 is a notch provided at an inner corner of the protective cover 200, which is formed into an L-shape by joining the first main body portion 200a and the second main body portion 200b. In this embodiment, the slit 220 is formed from the end on the insertion opening 210P side to the end on the insertion opening 210Q side. Therefore, by inserting the wiring material W through the slit 220 and storing it in the storage space portion 200S, the protective cover 200 can pull out the wiring material W from the insertion opening 210P side toward the insertion opening 210Q side (see FIG. 8).

[0024] The locking protrusion 230 is formed on the end of the first main body portion 200a, and is connected to the rear holder 120 by being locked by the locking frame portion 123 of the rear holder 120 (see FIG. 8).

[0025] The wiring material straightening component 300 is made of an insulating synthetic resin material and is attached to the wiring material W pulled out from the rear holder 120 to straighten the wiring path of the wiring material W. The wiring path of the wiring material W here refers to the wiring direction and position of the wiring material W inserted through the first main body portion 200a and the second main body portion 200b of the protective cover 200. As shown in FIG. 2, the wiring material straightening component 300 of this embodiment has a shape formed into a quadrant arc shape when viewed from the height direction Z. As shown in FIGS. 3 to 6, the wiring material straightening component 300 has a wiring material receiving groove 310 that receives the large-diameter wiring material WA in a bent state, a wiring material fixing protrusion 320 that holds the large-diameter wiring material WA received in the wiring material receiving groove 310, and a wiring material routing protrusion 330 that holds the small-diameter wiring material WB in a bent state.

[0026] The wiring material accommodating grooves 310 are U-shaped grooves defined and formed by the wall of the wiring material straightening component 300. As shown in Fig. 3, the wiring material accommodating grooves 310 of this embodiment are provided along the wiring material straightening component 300, which is formed in an arc shape. Two of the wiring material accommodating grooves 310 are provided on one side (upper side in the Z direction shown in Fig. 6) of the wiring material straightening component 300, and one is provided on the other side (lower side in the Z direction shown in Fig. 6). A large diameter wiring material WA is arranged in each of the three wiring material accommodating grooves 310. As shown in Figure 6, when viewed from the longitudinal direction X, the wiring material correction part 300 has a wiring material storage groove 313 located on the lower side in the Z direction, which is positioned between two wiring material storage grooves 311 and 312 located on the upper side in the Z direction, so that its shape when viewed from the longitudinal direction X is T-shaped.By storing large diameter wiring materials WA one by one in the wiring material storage grooves 310, the position of the large diameter wiring material WA can be corrected and the large diameter wiring material WA can be maintained in a bent state in an arc shape.

[0027] The wiring material fixing protrusions 320 are linear protrusions formed protruding from the inner surface side of the wiring material receiving groove 310. In this embodiment, the wiring material fixing protrusions 320 are provided in pairs in the width direction of the wiring material receiving groove 310, and the protrusions are arranged facing each other. Furthermore, a plurality of pairs of wiring material fixing protrusions 320 are provided at intervals in the extension direction of the wiring material receiving groove 310. Specifically, as shown in FIG. 3, the wiring material fixing protrusions 320 are provided at one end (the end on the housing 100 side), the middle portion, and the other end of the wiring material receiving groove 310, and a pair is provided at each location. Therefore, the wiring material straightening component 300 can hold the large-diameter wiring material WA received in the wiring material receiving groove 310 over the entire length of the wiring material receiving groove 310 by the wiring material fixing protrusions 320, and can more reliably determine the position of the large-diameter wiring material WA relative to the wiring material receiving groove 310.

[0028] The wiring material routing protrusion 330 is an L-shaped protrusion formed protruding from the outer surface side of the wiring material straightening component 300. As shown in FIG. 6, the wiring material routing protrusion 330 of this embodiment is formed on a step portion 300d of the wiring material straightening component 300 formed in a T-shape. The wiring material routing protrusion 330 is provided in pairs in the width direction (Y direction shown in FIG. 6) of the wiring material straightening component 300, and the L-shaped claw-shaped protrusions are arranged facing each other. Furthermore, a plurality of pairs of wiring material routing protrusions 330 are provided at intervals in the extension direction of the wiring material receiving groove 310. Specifically, as shown in FIGS. 4 and 5, the wiring material routing protrusions 330 are provided at two locations, one end (the end on the housing 100 side) and the other end of the wiring material straightening component 300, and a pair is provided at each location. Therefore, the wiring material straightening component 300 can hold the small diameter wiring material WB over the entire length of the wiring material straightening component 300 by the wiring material routing protrusion 330, and the position of the small diameter wiring material WB relative to the wiring material straightening component 300 can be more reliably determined. Also, as shown in FIG. 6, the wiring material routing protrusion 330 is provided on the side wall portion of the wiring material accommodating groove 313 located on the lower side in the Z direction, and is thereby arranged in a recess of the wiring material straightening component 300. Therefore, by providing a protrusion on the outer surface of the wiring material straightening component 300, it is possible to prevent the size of the wiring material straightening component 300 from becoming even larger. Also, by routing the small diameter wiring material WB in a recessed portion of the wiring material straightening component 300, it is possible to prevent the small diameter wiring material WB from being caught and pulled by other components during assembly.

[0029] Next, the assembly operation of the connector 1 will be described with reference to FIGS.

[0030] First, the worker assembles the wiring material W into the housing 100. At this time, the terminal T is held in the housing main body 110. Then, the three large diameter wiring materials WA and the six small diameter wiring materials WB are pulled out from the end of the rear holder 120 assembled to the housing main body 110.

[0031] Then, the worker prepares the wiring material straightening component 300 and fits the three large-diameter wiring materials WA into the wiring material receiving grooves 310 of the wiring material straightening component 300 (see FIG. 7). At this time, each large-diameter wiring material WA is pushed into an opening 310K that opens in the height direction Z of the wiring material receiving groove 310, and is routed from the insertion opening 310P side located at the end (the end on the housing 100 side) of the wiring material receiving groove 310 toward the insertion opening 310Q side. Each large-diameter wiring material WA is clamped by a wiring material fixing protrusion 320 provided on the inner surface of the wiring material receiving groove 310, and its position relative to the wiring material straightening component 300 is fixed. Therefore, the three large-diameter wiring materials WA pulled out from the end of the rear holder 120 are fitted into the wiring material receiving grooves 310 of the wiring material straightening component 300, and the bent shape bending from the length direction X to the width direction Y is maintained.

[0032] Then, the worker hooks each of the six small diameter wiring materials WB onto the wiring material arrangement protrusions 330 of the wiring material straightening component 300. At this time, the six small diameter wiring materials WB are divided into groups of three and are held by the wiring material arrangement protrusions 330 (see FIG. 4) provided at the outer corners of the wiring material straightening component 300 and the wiring material arrangement protrusions 330 (see FIG. 5) provided at the inner corners, respectively, of the wiring material straightening component 300, so that the six small diameter wiring materials WB are arranged along the outer shape of the wiring material straightening component 300. Therefore, the six small diameter wiring materials WB pulled out from the rear holder 120 are held in the wiring material accommodation grooves 310 of the wiring material straightening component 300, so that the bent shape bending from the length direction X toward the width direction Y is maintained.

[0033] Then, the worker prepares the protective cover 200 and covers the wiring material straightening component 300 attached to the wiring material W pulled out from the end of the housing 100 with the protective cover 200 (see FIG. 8). At this time, the wiring material straightening component 300 is inserted through the slit 220 of the protective cover 200 and placed inside the protective cover 200 (the storage space 200S). The wiring material straightening component 300, which is formed in a quadrant arc shape, is placed at the corner portion of the protective cover 200, which is formed in an L-shape. The large diameter wiring material WA and the small diameter wiring material WB are pulled out from the insertion opening 210P side of the protective cover 200 toward the insertion opening 210Q side while maintaining their bent shapes bending from the length direction X toward the width direction Y. The protective cover 200 is then assembled to the end of the rear holder 120 by fitting the locking protrusion 230 into the locking frame 123 of the rear holder 120. Therefore, the large diameter wiring material WA and the small diameter wiring material WB pulled out from the end of the rear holder 120 are inserted into the protective cover 200 in a state bent from the pulling-out direction. Then, the wiring direction and position of the large diameter wiring material WA and the small diameter wiring material WB are corrected by the wiring material correction part 300.

[0034] The connector 1 described above comprises a housing 100 that accommodates and holds a terminal T connected to the end of a conductive wiring material W, and from whose end the wiring material W is pulled out, a protective cover 200 that is assembled to the end of the housing 100 and through which the wiring material W pulled out from the housing 100 is inserted in a state bent from the pulling direction, and a wiring material straightening part 300 that is arranged inside the protective cover 200 and holds the wiring material W, thereby maintaining the bent shape of the wiring material W.

[0035] According to this configuration, the wiring material W pulled out from the housing 100 can be routed using the wiring material straightening component 300 to correct the routing direction and position of the wiring material W. Therefore, the wiring material W is inserted into the protective cover 200 at the proper position and routed in a bent state according to the shape of the protective cover 200. Therefore, the connector 1 of the present invention can properly route the wiring material W pulled out from the housing 100. Furthermore, correcting the bending of the wiring material W using the wiring material straightening component 300 can prevent the wiring material W from returning in the direction opposite to the bending direction due to a repulsive force (a force that repels bending of the wiring material). Therefore, it is possible to prevent the terminal T connected to the end of the wiring material W from moving due to a reaction force of the repulsive force generated in the wiring material W, which results in a decrease in the alignment accuracy of the terminal T with respect to the housing 100. Furthermore, correcting the bending of the wiring material W using the wiring material straightening component 300 can reduce the bending radius of the wiring material W. Therefore, the wiring material straightening component 300 can prevent the size of the protective cover 200 that houses the wiring material W from becoming large, and can contribute to measures to make the connector 1 smaller.

[0036] Furthermore, the wiring material W assembled to the connector 1 described above includes a large-diameter wiring material WA as a first wiring material, and the wiring material straightening component 300 has a wiring material accommodation groove 310 that accommodates the large-diameter wiring material WA in a bent state, and a wiring material fixing protrusion 320 formed on the inner surface of the wiring material accommodation groove 310 and capable of holding the large-diameter wiring material WA accommodated in the wiring material accommodation groove 310. With this configuration, the wiring direction and position of the large-diameter wiring material WA can be corrected by routing the large-diameter wiring material WA along the wiring material accommodation groove 310. Furthermore, by accommodating the large-diameter wiring material WA one by one in the wiring material accommodation groove 310, it becomes easier to route the large-diameter wiring material WA, improving work efficiency. In addition, when a plurality of wiring material accommodation grooves 310 are provided in the wiring material straightening component 300, the repulsive force generated when bending the large-diameter wiring material WA is prevented from being applied to adjacent large-diameter wiring materials WA, thereby preventing the large-diameter wiring materials WA from shifting in position, and allowing each of the plurality of large-diameter wiring materials WA to be properly arranged. In addition, by holding the large-diameter wiring material WA accommodated in the wiring material accommodation groove 310 with the wiring material fixing protrusion 320, it is possible to prevent the large-diameter wiring material WA from coming off the wiring material accommodation groove 310 due to external forces generated by vibrations, etc.

[0037] Furthermore, the wiring material W assembled to the connector 1 described above includes a small-diameter wiring material WB as a second wiring material, and the wiring material straightening component 300 has a wiring material routing protrusion 330 formed on the outer surface thereof that can hold the small-diameter wiring material WB in a bent state. With this configuration, the wiring direction and position of the small-diameter wiring material WB can be corrected by routing the small-diameter wiring material WB along the outer surface of the wiring material straightening component 300. In addition, since the small-diameter wiring material WB can be held until the terminal T connected to the wiring material W is assembled into the housing 100, the assembly of the connector 1 is facilitated and work efficiency can be improved. Furthermore, if the wiring material W to be assembled to the connector 1 includes a large-diameter wiring material WA and a small-diameter wiring material WB with different outer diameters, by wiring the large-diameter wiring material WA and the small-diameter wiring material WB separately, the force applied when bending the large-diameter wiring material WA can be prevented from being applied to the small-diameter wiring material WB, and external forces such as tension can be prevented from being applied to the small-diameter wiring material WB.

[0038] [Second embodiment] Next, a connector 1A according to a second embodiment shown in Figures 9 and 10 will be described. The connector 1A differs from the connector 1 according to the first embodiment in that a wiring material straightening component cover 400 is assembled to a wiring material straightening component 300A. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0039] As shown in Fig. 9, the wiring material straightening component 300A has a shape of a quadrant arc when viewed from the height direction Z. As shown in Fig. 10, the wiring material straightening component 300A has a wiring material accommodation groove 310 that accommodates the large diameter wiring material WA in a bent state, a wiring material fixing protrusion 320 that holds the large diameter wiring material WA accommodated in the wiring material accommodation groove 310, and a locking protrusion portion 340.

[0040] The wiring material straightening component cover 400 is formed in a plate shape and is formed to a size that can close the opening 310K of the wiring material accommodating groove 310, so that when the opening 310K of the wiring material accommodating groove 310 is closed (see FIG. 10, etc.), it is a part that extends along the length direction X and the width direction Y. The wiring material straightening component cover 400 of this embodiment has a wiring material routing protrusion 410 that holds the small diameter wiring material WB in a bent state, and a locking frame portion 420 that is provided corresponding to the locking protrusion portion 340 of the wiring material straightening component 300A. In addition, the wiring material straightening component cover 400 is composed of a wiring material straightening component cover 401 that can collectively close the two wiring material storage grooves 311, 312 provided on one side of the wiring material straightening component 300A (the upper side in the Z direction shown in Figure 10), and a wiring material straightening component cover 402 that can close the wiring material storage groove 313 provided on the other side of the wiring material straightening component 300A (the lower side in the Z direction shown in Figure 10), and the wiring material straightening component cover 401 and the wiring material straightening component cover 402 are positioned facing each other when assembled to the wiring material straightening component 300A.

[0041] The wiring material arrangement protrusion 410 is a protrusion formed on a side wall portion formed to protrude in the height direction Z from the ceiling portion of the wiring material straightening component cover 402 that covers the wiring material accommodating groove 313, and is an L-shaped protrusion formed to protrude from the outer surface side of the side wall portion. As shown in FIG. 10, the wiring material arrangement protrusion 410 of this embodiment is formed on a step portion 300dA of the wiring material straightening component 300A that is formed in a T-shape. Similarly to the wiring material arrangement protrusion 330 described above, the wiring material arrangement protrusion 410 is provided in pairs in the width direction (Y direction shown in FIG. 10), and the L-shaped claw-shaped protrusions are arranged facing each other. In addition, a plurality of pairs of wiring material arrangement protrusions 410 are provided at intervals in the extension direction of the wiring material accommodating groove 310, and are provided at two locations, one end (the end on the housing 100 side) and the other end of the wiring material straightening component cover 402, and a pair is provided at each location.

[0042] The locking frame portion 420 is a frame portion formed on a side wall portion formed to protrude in the height direction Z from the ceiling portion of the wiring material straightening component cover 400 formed in a plate shape. The locking frame portion 420 of this embodiment is held in a position to close the opening 310K of the wiring material accommodating groove 310 of the wiring material straightening component 300A by being locked to the locking protrusion portion 340 of the wiring material straightening component 300A. Then, the wiring material straightening component cover 400 is assembled to the wiring material straightening component 300A by fitting the locking protrusion portion 340 and the locking frame portion 420 together.

[0043] Next, the assembly operation of the connector 1A will be described with reference to FIGS.

[0044] First, the worker assembles the wiring material W to the housing 100. Then, the worker prepares the wiring material straightening component 300A and fits three large-diameter wiring materials WA into the wiring material receiving grooves 310 of the wiring material straightening component 300A (see FIG. 11). At this time, each large-diameter wiring material WA is pushed into an opening 310K that opens in the height direction Z of the wiring material receiving groove 310, and is wired from the insertion opening 310P side located at the end (the end on the housing 100 side) of the wiring material receiving groove 310 toward the insertion opening 310Q side. Then, each large-diameter wiring material WA is clamped by a wiring material fixing protrusion 320 provided on the inner surface of the wiring material receiving groove 310, and its position relative to the wiring material straightening component 300A is fixed.

[0045] Then, the worker prepares the wiring material straightening component cover 400, and assembles the wiring material straightening component cover 400 to the wiring material straightening component 300A while routing each of the six small diameter wiring materials WB along the side wall portion of the wiring material straightening component 300A (see FIG. 12). At this time, the wiring material straightening component cover 400 is assembled to the wiring material straightening component 300A by fitting the locking frame portion 420 with the locking protrusion portion 340 of the wiring material straightening component 300A. Then, the small diameter wiring materials WB are held by the wiring material routing protrusions 410 provided at the outer corners of the wiring material straightening component cover 402 and the wiring material routing protrusions 410 provided at the inner corners, respectively.

[0046] Then, the worker prepares the protective cover 200 and covers the wiring material straightening component 300A attached to the wiring material W pulled out from the end of the housing 100 and the wiring material straightening component cover 400 attached to the wiring material straightening component 300A with the protective cover 200 (see FIG. 13). At this time, the wiring material straightening component 300A and the wiring material straightening component cover 400 are inserted through the slit 220 of the protective cover 200 and placed inside the protective cover 200 (the storage space 200S). Then, the wiring material straightening component 300A formed in the shape of a quadrant is placed in the corner part of the protective cover 200 formed in an L-shape, and the large diameter wiring material WA and the small diameter wiring material WB are pulled out from the insertion opening 210P side of the protective cover 200 toward the insertion opening 210Q side while maintaining the bent shape bending from the length direction X toward the width direction Y. The protective cover 200 is assembled to the end of the rear holder 120 by fitting the locking protrusion 230 into the locking frame 123 of the rear holder 120. Therefore, the large diameter wiring material WA and the small diameter wiring material WB pulled out from the rear holder 120 are inserted into the protective cover 200 in a state where they are bent from the pulling direction. The wiring direction and position of the large diameter wiring material WA and the small diameter wiring material WB are corrected by the wiring material correction part 300A.

[0047] According to this configuration, the wiring material W pulled out from the end of the housing 100 can be routed using the wiring material straightening component 300A, thereby correcting the routing direction and position of the wiring material W. Therefore, the wiring material W is inserted into the protective cover 200 at the appropriate position and routed in a bent state according to the shape of the protective cover 200. Therefore, similar to the connector 1 described above, the connector 1A of the present invention can properly route the wiring material W pulled out from the housing 100. Furthermore, by closing the wiring material receiving groove 310 of the wiring material straightening component 300 with the wiring material straightening component cover 400, it is possible to more reliably prevent the large-diameter wiring material WA from slipping out of the wiring material receiving groove 310. Furthermore, by holding the small-diameter wiring material WB in the wiring material routing protrusion 410 provided on the wiring material straightening component cover 400, it is possible to prevent external forces such as tension from being applied to the small-diameter wiring material WB.

[0048] The connectors 1, 1A according to the above-described embodiments of the present invention are not limited to the above-described embodiments, and various modifications are possible within the scope of the claims.

[0049] For example, the housing 100 may be a part in which the housing main body 110 and the rear holder 120 are integrally formed, or may include components other than the housing main body 110 and the rear holder 120.

[0050] In addition, the connector 1, 1A may have only the large diameter wiring material WA routed therein, or may have only the small diameter wiring material WB routed therein. Furthermore, the number of the large diameter wiring material WA or the small diameter wiring material WB pulled out from the housing 100 is not particularly limited, and the number of the wiring material accommodating groove 310, the wiring material fixing protrusion 320, and the wiring material routing protrusion 330 (or the wiring material routing protrusion 410) is not particularly limited.

[0051] The connector according to this embodiment may be configured by appropriately combining the components of the embodiments and modified examples described above. [Explanation of symbols]
