[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. The connector of the present disclosure comprises: (1) A housing body in which a module accommodating chamber and a wiring space are formed, a cover for closing an opening of the wiring space on the outer surface of the housing body, a pressing member attached in the wiring space, and a terminal module having terminal fittings connected to electric wires and inserted in the module accommodating chamber, the electric wire led out from the module accommodating chamber into the wiring space is sandwiched between the cover and the pressing member and wired in a bent state, and the mounting direction of the pressing member is a direction approaching the module accommodating chamber. According to this configuration, since a strain relief portion is formed by the cover and the pressing member, even if a tensile force acts on the electric wire outside the housing body, the tensile force does not reach the connection portion between the electric wire and the terminal fitting. In the process of mounting the pressing member in the wiring space, the pressing member presses the portion of the electric wire that is wired in the wiring space toward the module accommodating chamber, so that no tensile force acts between the electric wire and the terminal fitting. Therefore, damage to the connection portion between the electric wire and the terminal fitting can be suppressed.

[0010] (2) It is preferable that the pressing member has a pressing surface facing the module accommodating chamber, the cover has a protrusion that protrudes in a direction intersecting the mounting direction of the pressing member and is disposed in the wiring space, the protrusion has a receiving surface that sandwiches the electric wire between itself and the pressing surface, and the mounting direction of the cover to the housing main body is the same as the protruding direction of the protrusion. According to this configuration, when the cover is attached to the housing main body with the pressing member removed from the housing main body, the electric wire is pressed by the protrusion. When the pressing member is attached in this state, the electric wire is pressed by the pressing surface toward the module accommodating chamber, and is sandwiched between the pressing surface and the receiving surface and bent.

[0011] (3) The electric wire includes two signal lines constituting a differential pair wire, and the differential pair wire is preferably embedded in a sheath in a twisted state to form a single shielded cable, and the portion of the differential pair wire embedded in the sheath is sandwiched and bent between the cover and the pressing member. With this configuration, the untwisted length of the differential pair wire can be shortened, resulting in excellent communication performance. The portion of the differential pair wire exposed from the sheath has low rigidity, and is therefore likely to be displaced in the axial direction even when sandwiched between the cover and the pressing member. In contrast, the portion of the shielded cable where the differential pair wire is embedded in the sheath has higher rigidity than the exposed portion of the differential pair wire, and is therefore less likely to be displaced in the axial direction when sandwiched between the cover and the pressing member.

[0012] (4) It is preferable that the electric wire includes a power line and a ground wire, and the power line and the ground wire are embedded in an insulating sheath to form a single multi-core cable, and that the portions of the power line and the ground wire embedded in the insulating sheath are sandwiched between the cover and the pressing member and bent. The portions of the power line and the ground wire exposed from the insulating sheath have low rigidity, and are therefore likely to be displaced in the axial direction even when sandwiched between the cover and the pressing member. In contrast, the portions of the multi-core cable where the power line and the ground wire are embedded in the insulating sheath have higher rigidity than the exposed portions of the power line and the ground wire, and are therefore less likely to be displaced in the axial direction when sandwiched between the cover and the pressing member.

[0013] (5) It is preferable that the electric wire is embedded in a plurality of cables, the plurality of cables are arranged in the wiring space so as to be aligned in a width direction intersecting the wiring direction of the plurality of cables, and the pressing member has a partition wall that separates the plurality of cables. With this configuration, it is possible to prevent the plurality of cables from being arranged unevenly in the width direction in the wiring space.

[0014] [Details of the embodiment of the present disclosure] [Example 1] A first embodiment of the present disclosure will be described with reference to Figs. 1 to 6. Note that the present invention is not limited to these examples, but is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In this first embodiment, the front-rear direction is defined as the positive direction of the X-axis in Figs. 1 to 6 as the front. The left-right direction is defined as the positive direction of the Y-axis in Figs. 1 and 2 as the right. The up-down direction is defined as the positive direction of the Z-axis in Figs. 1 to 6 as the up.

[0015] 1 to 3, the connector of the first embodiment is configured by assembling a housing 10 and a terminal module 60. The housing 10 is configured by assembling a housing body 11 made of synthetic resin, a cover 30 made of synthetic resin, a pressing member 40 made of synthetic resin, a rubber plug 50, and a holder 55 made of synthetic resin.

[0016] The housing body 11 is a single part. As shown in Figs. 2 to 6, an arrangement space 12 is formed inside the housing body 11. A rear opening 13 communicating with the arrangement space 12 is formed on the rear surface of the outer surface of the housing body 11. As shown in Figs. 3 to 6, a lower opening 14 communicating with the arrangement space 12 is formed on the lower surface of the outer surface of the housing body 11 that is perpendicular to the rear surface. A module accommodating chamber 15 having a shape penetrating the housing body 11 in the front-rear direction is formed on the upper end of the housing body 11. The front end of the module accommodating chamber 15 opens to the front surface of the housing body 11. The rear end of the module accommodating chamber 15 communicates with the upper end space of the arrangement space 12 and is exposed to the outside of the housing body 11 at the rear opening 13.

[0017] An upper pressing portion 17 and a lower pressing portion 18 are formed in an upper end region of the front wall portion 16 that constitutes the wiring space 12. The upper pressing portion 17 faces the wiring space 12 and has a protruding shape that bulges diagonally downward from the rear surface of the front wall portion 16. The lower pressing portion 18 faces the wiring space 12 and has a protruding shape that bulges diagonally downward from the rear surface of the front wall portion 16. The lower pressing portion 18 is located below the upper pressing portion 17 and is located behind the upper pressing portion 17. In a side view of the housing main body 11 seen from the side, the region of the rear surface of the front wall portion 16 where the upper pressing portion 17 and the lower pressing portion 18 are formed is inclined in an overhanging shape so as to become lower toward the front.

[0018] An area of ​​the routing space 12 below the lower presser portion 18 functions as an accommodation space 19 for accommodating a presser member 40 described below. An area of ​​the rear surface of the front wall portion 16 that constitutes the accommodation space 19 is located forward of the lower presser portion 18. In other words, the rear surface of the front wall portion 16 is recessed forward relative to the lower presser portion 18. An upper surface of the accommodation space 19 functions as a stopper 20 that faces downward (toward the bottom opening 14).

[0019] A pair of locking portions 21 (see FIG. 2) extending in the vertical direction are formed on the inner surfaces of both left and right side wall portions that form the wiring space 12. The front end of the locking portion 21 has a stepped shape that forms a locking surface (not shown) that faces forward (the side opposite the rear opening 13 in the front-rear direction). A pair of upper and lower guide portions 22 are formed on the inner surfaces facing each other of the two locking portions 21. The guide portions 22 are groove-shaped and inclined so as to become gradually shallower toward the front. A pair of locking protrusions 23 are formed on both left and right outer side surfaces of the housing main body 11.

[0020] As shown in FIG. 2, the cover 30 is a single part having a plate-shaped main body 31, one protrusion 32, and two pairs of elastic locking pieces 36. The plate-shaped main body 31 has a shape and size to cover the rear opening 13. The protrusion 32 protrudes forward from the front surface of the plate-shaped main body 31. As shown in FIGS. 4 to 6, the upper surface (upper end region on the front surface) of the protrusion 32 forms a support surface 33 that is gradually lower toward the front. The lower surface (lower end region on the front surface) of the protrusion 32 forms a receiving surface 34 that is gradually higher toward the front. The protrusion 32 is formed with a groove 35. The groove 35 is shaped such that the entire region from the upper end to the lower end on the front surface of the protrusion 32 is recessed in the shape of a vertical slit.

[0021] As shown in Fig. 2, the elastic locking pieces 36 extend forward in a cantilever shape from both left and right side edges of the plate-shaped main body 31. A pair of elastic locking pieces 36 spaced apart in the up-down direction is disposed on each side edge. A locking protrusion 37 is formed on the front end of each elastic locking piece 36. The elastic locking pieces 36 are capable of elastic deformation in the left-right direction.

[0022] The cover 30 is attached to the rear part of the housing body 11 so as to close the rear opening 13. In the process of attaching the cover 30, the locking projections 37 fit into the guide parts 22, so that the cover 30 is positioned in the up-down and left-right directions with respect to the housing body 11, and the cover 30 is guided to move in the front-rear direction. In the process of attaching the cover 30, the locking projections 37 slide against the guide parts 22, so that the elastic locking pieces 36 are elastically deformed. When the cover 30 is attached to the housing body 11, the plate-shaped main body part 31 closes the entire area of ​​the rear opening 13. The elastic locking pieces 36 elastically return to their original state, and the locking projections 37 lock with the front ends of the locking parts 21 from the front. This locking keeps the cover 30 attached to the housing body 11.

[0023] When the cover 30 is attached to the housing body 11, the protrusion 32 is disposed within the routing space 12, and the upper end region of the support surface 33 faces the upper and lower pressing portions 17 and 18 in the front-to-rear direction at the same height. In a side view, the support surface 33 is parallel to an imaginary line connecting the rearward protruding end of the upper pressing portion 17 and the rearward protruding end of the lower pressing portion 18. The lower end region of the support surface 33 is disposed at the same height as the upper end region of the storage space 19. The receiving surface 34 is disposed at the same height as the lower end region of the storage space 19.

[0024] As shown in Fig. 2, the pressing member 40 is a single part having a wall-shaped base 41 and a partition wall 44. The wall-shaped base 41 is a portion whose wall thickness direction faces the front-rear direction. In a front view of the pressing member 40 seen from the front, the wall-shaped base 41 is rectangular. As shown in Figs. 2, 5 and 6, a pressing portion 42 is formed in the lower end region of the rear surface of the wall-shaped base 41. A pressing surface 43 is formed on the side surface of the upper end region of the front surface of the pressing portion 42, which is gradually inclined toward the rear.

[0025] The partition wall 44 protrudes rearward in a cantilever shape from the rear surface of the wall-shaped base 41 and the center position in the left-right direction of the pressing portion 42. The partition wall 44 has a wall thickness direction oriented in the left-right direction and has a rectangular shape in a side view. The partition wall 44 is formed in a vertical area ranging from the upper end to the lower end of the wall-shaped base 41.

[0026] The pressing member 40 is attached in the wiring space 12 by passing it through the bottom opening 14 from below the housing body 11. When the pressing member 40 is attached, the wall-shaped base 41 is arranged so as to overlap the rear surface of the front wall portion 16 of the housing body 11. The upper end of the wall-shaped base 41 abuts against the stopper 20 of the housing body 11 from below, so that the pressing member 40 is positioned in the up-down direction with respect to the housing body 11. The pressing portion 42 and the pressing surface 43 of the pressing member 40 are located forward of the front end of the protrusion 32 of the cover 30. The pressing surface 43 and the receiving surface 34 of the cover 30 are at the same height and are positioned opposite each other in the front-rear direction. In a side view, the pressing surface 43 and the receiving surface 34 are parallel to each other. The rear end edge of the partition wall 44 is fitted into the groove portion 35 of the cover 30. The interior of the wiring space 12 is divided into two chambers, left and right, by the partition wall 44.

[0027] The rubber stopper 50 is a single part having a pair of left and right seal holes 51. The seal holes 51 penetrate the rubber stopper 50 in the up-down direction. A lip portion 52 is formed on the outer circumferential surface of the rubber stopper 50. The holder 55 is a single part having a plate-shaped pressing portion 56 and a pair of left and right lock arms 58. The plate-shaped pressing portion 56 is a portion whose plate thickness direction faces the up-down direction. A pair of left and right cable insertion holes 57 are formed in the plate-shaped pressing portion 56. The pair of lock arms 58 are shaped to extend upward in a cantilever manner from both left and right side edges of the plate-shaped pressing portion 56.

[0028] 3 and 6, the terminal module 60 has a synthetic resin case 61 and two pairs of terminal fittings 62 housed in the case 61. The two pairs of terminal fittings 62 are housed in two separate levels, upper and lower. The terminal fittings 62 are a single component having a rectangular cylindrical terminal main body 63 and a crimping portion 64 connected to the rear end of the terminal main body 63.

[0029] Of the two terminal fittings 62 housed in the upper side of the case 61, a power line 71 (see FIG. 2) made of a coated electric wire is connected to the crimping portion 64 of one of the terminal fittings 62. A ground wire 72 (see FIG. 2) made of a coated electric wire is connected to the crimping portion 64 of the other terminal fitting 62. The power line 71 and the ground wire 72 are embedded in a common insulating sheath 73. The power line 71, the ground wire 72, and the insulating sheath 73 form one multi-core cable 70. The cross-sectional shape of the multi-core cable 70 (insulating sheath 73) is circular. The end of the multi-core cable 70 connected to the terminal fitting 62 forms the terminal module 60.

[0030] As shown in FIGS. 3 and 6, a signal line 76 (see FIG. 2) made of a coated electric wire is connected to each of the crimping portions 64 of the two terminal fittings 62 housed in the lower section of the case 61. The two signal lines 76 form a differential pair wire 77. The differential pair wires 77 are embedded in a common sheath 78 in a twisted state. The differential pair wires 77 form a twisted pair wire. The differential pair wires 77 and the sheath 78 form one shielded cable 75. The cross-sectional shape of the shielded cable 75 (sheath 78) is circular. The end of the shielded cable 75 connected to the terminal fittings 62 forms the terminal module 60.

[0031] In the terminal module 60, the end of the insulating coating 73 and the end of the sheath 78 are located near the case 61. In other words, the length of the power line 71 and the earth line 72 exposed from the insulating coating 73 is set to the minimum length required to attach the terminal fitting 62 to the case 61. Sheath 78 The length exposed from the terminal fitting 62 is set to the minimum length required for attaching the terminal fitting 62 to the case 61.

[0032] The rubber plug 50 and holder 55 are attached to the multi-core cable 70 and the shielded cable 75 before the terminal module 60 is attached to the housing body 11. The multi-core cable 70 and the shielded cable 75 are inserted through the seal hole 51 of the rubber plug 50 and the cable insertion hole 57 of the holder 55. The rubber plug 50 is disposed at a position closer to the terminal fitting 62 than the holder 55 is.

[0033] Next, the procedure for assembling the connector will be described. The terminal module 60 is inserted into the wiring space 12 from the bottom opening 14, and is pulled out to the rear of the housing body 11 from the rear opening 13. The pulled out terminal module 60 is inserted into the module accommodating chamber 15 from the rear opening 13. The terminal module 60 inserted into the module accommodating chamber 15 is prevented from being pulled out by a stopper (not shown) provided on the housing body 11.

[0034] The upper end of the insulating coating 73 of the multi-core cable 70 and the upper end of the sheath 78 of the shielded cable 75 are located at approximately the same height as the upper pressing portion 17. The portions of the multi-core cable 70 where the power line 71 and the earth line 72 are exposed have lower rigidity than the portions embedded in the insulating coating 73, so they are bent with a relatively large curvature and arranged in the wiring space 12. The areas of the power line 71 and the earth line 72 embedded in the insulating coating 73 are also arranged in the wiring space 12. The portions of the shielded cable 75 where the signal line 76 is exposed have lower rigidity than the portions embedded in the sheath 78, so they are bent with a relatively large curvature and arranged in the wiring space 12. The areas of the signal line 76 embedded in the sheath 78 are also arranged in the wiring space 12.

[0035] After the terminal module 60 is attached, the cover 30 is attached to the housing body 11. In the process of attaching the cover 30, the front end of the protrusion 32 comes into contact with the insulating coating 73 and the sheath 78, and pushes the multi-core cable 70 and the shielded cable 75 forward. At this time, the power line 71, the earth line 72, and the signal line 76, which have a relatively low rigidity, flex and deform flexibly, so that a large load (tensile force) is not applied to the connection part between the power line 71 and the terminal fitting 62, the connection part between the earth line 72 and the terminal fitting 62, and the connection part between the signal line 76 and the terminal fitting 62. When the cover 30 is attached to the housing body 11, the insulating coating 73 and the sheath 78 are pressed against the upper pressing part 17 and the lower pressing part 18 by the support surface 33. The multi-core cable 70 and the shielded cable 75 are clamped between the housing body 11 and the cover 30 in the front-rear direction.

[0036] After the cover 30 is attached, the pressing member 40 is attached to the housing body 11. The pressing member 40 is attached upward. In the process of attaching the pressing member 40, the pressing portion 42 contacts the insulating coating 73 and the sheath 78 from the front, so that frictional resistance is generated between the pressing member 40 and the multi-core cable 70 and the shielded cable 75. This frictional force applies an upward pressing force to the multi-core cable 70 and the shielded cable 75. Therefore, no tensile force is applied to the connection portion between the crimping portion 64 of the terminal fitting 62 and the power line 71, the connection portion between the crimping portion 64 of the terminal fitting 62 and the earth wire 72, and the connection portion between the crimping portion 64 of the terminal fitting 62 and the signal line 76.

[0037] When the pressing member 40 is attached to the housing main body 11, the multi-core cable 70 and the shielded cable 75 are sandwiched in the front-rear direction between the pressing surface 43 and the receiving surface 34. In a side view, the inclination direction of the portions of the multi-core cable 70 and the shielded cable 75 sandwiched between the support surface 33 and the upper pressing portion 17 and the lower pressing portion 18 is different from the inclination direction of the portions sandwiched between the pressing surface 43 and the receiving surface 34. The multi-core cable 70 and the shielded cable 75 are pushed forward by the front end of the protrusion 32 and pushed backward by the rear end of the pressing portion 42, and are arranged in a bent state in a side view.

[0038] After the pressing member 40 is attached, the rubber stopper 50 and the holder 55 are slid upward so that the lock arm 58 of the holder 55 engages with the lock protrusion 23 of the housing body 11. This keeps the pressing member 40 attached within the wiring space 12, and keeps the rubber stopper 50 and the holder 55 attached to the housing body 11. This completes the assembly of the connector.

[0039] When the multi-core cable 70 and the shielded cable 75 are pulled downward outside the connector, the insulating coating 73 of the multi-core cable 70 and the sheath 78 of the shielded cable 75 are caught on the lower edge of the pressing surface 43 of the pressing portion 42 and are also caught on the front end (the lower edge of the support surface 33) of the protrusion 32. This catch restricts the downward movement of the multi-core cable 70 and the shielded cable 75. Therefore, no load in the tensile direction is applied to the connection portion between the terminal fitting 62 and the power line 71, the connection portion between the terminal fitting 62 and the earth wire 72, and the connection portion between the terminal fitting 62 and the signal line 76.

[0040] The connector of the first embodiment includes a housing body 11, a cover 30, a pressing member 40, and a terminal module 60. The housing body 11 includes a module accommodating chamber 15 and a wiring space 12. The cover 30 closes an opening (rear opening 13) of the wiring space 12 on the outer surface of the housing body 11. The pressing member 40 is attached to the wiring space 12. The terminal module 60 includes a terminal fitting 62 connected to any one of a power line 71, a ground line 72, and a signal line 76, and is inserted into the module accommodating chamber 15. The power line 71, the ground line 72, and the signal line 76 led from the module accommodating chamber 15 into the wiring space 12 are sandwiched between the cover 30 and the pressing member 40 and are arranged in a bent state. The pressing member 40 is attached in a direction approaching the module accommodating chamber 15, i.e., an upward direction.

[0041] In the housing 10, a strain relief portion 79 is formed by the upper pressing portion 17 and the lower pressing portion 18 of the housing body 11, the protrusion 32 of the cover 30, and the pressing portion 42 of the pressing member 40. Even if a tensile force acts on the multi-core cable 70 (power line 71 and earth line 72) and the shielded cable 75 (signal line 76) electric wires outside the housing body 11, the strain relief portion 79 prevents the tensile force from reaching the connection portion between these electric wires 71, 72, 76 and the terminal fittings 62. In the process of attaching the pressing member 40 to the wiring space 12, the pressing member 40 presses the portions of the electric wires 71, 72, 76 that are routed in the wiring space 12 toward the module accommodating chamber 15, so that no tensile force acts between the electric wires 71, 72, 76 and the terminal fittings 62. Therefore, damage to the connection portion between the electric wires 71, 72, 76 and the terminal fittings 62 can be suppressed.

[0042] The pressing member 40 has a pressing surface 43 facing the module accommodating chamber 15. The cover 30 has a protrusion 32 protruding in a direction intersecting the mounting direction of the pressing member 40. The protrusion 32 is disposed in the wiring space 12. The protrusion 32 has a receiving surface 34 for sandwiching the electric wires 71, 72, 76 (the multi-core cable 70 and the shielded cable 75) between the protrusion 32 and the pressing surface 43. The mounting direction of the cover 30 to the housing main body 11 is the same direction (forward) as the protrusion 32 protruding direction. When the cover 30 is mounted to the housing main body 11 with the pressing member 40 removed from the housing main body 11, the electric wires 71, 72, 76 (the multi-core cable 70 and the shielded cable 75) are pressed forward by the protrusion 32. When the pressing member 40 is attached in this state, the electric wires 71, 72, 76 (the multi-core cable 70 and the shielded cable 75) are pressed toward the module accommodating chamber 15 by the lower edge of the pressing surface 43, and are sandwiched between the pressing surface 43 and the receiving surface 34 and bent.

[0043] The electric wires 71, 72, and 76 include two signal wires 76 constituting a differential pair wire 77. The differential pair wires 77 (two signal wires 76) are twisted together and embedded in a sheath 78 to form one shielded cable 75. The portion of the differential pair wires 77 embedded in the sheath 78 is sandwiched between the cover 30 and the pressing member 40 and bent. With this configuration, the untwisted length of the differential pair wires 77 (the exposed length from the sheath 78) can be shortened, resulting in excellent communication performance. The portion of the differential pair wires 77 exposed from the sheath 78 has low rigidity, so that even if it is sandwiched between the cover 30 and the pressing member 40, it is likely to be displaced in the axial direction (up and down direction). In contrast, the portion of the shielded cable 75 where the differential pair wires 77 are embedded in the sheath 78 has higher rigidity than the exposed portion of the differential pair wires 77, so that it is unlikely to be displaced in the axial direction by being sandwiched between the cover 30 and the pressing member 40.

[0044] The electric wires 71, 72, 76 include a power line 71 and a ground wire 72. The power line 71 and the ground wire 72 are embedded in an insulating sheath 73 having the same diameter as the sheath 78 to form one multi-core cable 70. The shielded cable 75 and the multi-core cable 70 are arranged in parallel in the width direction (left-right direction). The parts of the power line 71 and the ground wire 72 embedded in the insulating sheath 73 are sandwiched between the cover 30 and the pressing member 40 and bent. The parts of the power line 71 and the ground wire 72 exposed from the insulating sheath 73 have low rigidity, so that they are likely to be displaced in the axial direction (up-down direction) even when sandwiched between the cover 30 and the pressing member 40. In contrast, the parts of the multi-core cable 70 where the power line 71 and the ground wire 72 are embedded in the insulating sheath 73 have higher rigidity than the exposed parts of the power line 71 and the ground wire 72, so that they are unlikely to be displaced in the axial direction when sandwiched between the cover 30 and the pressing member 40.

[0045] The connector has two (multiple) cables (a multi-core cable 70 and a shielded cable 75) in which electric wires 71, 72, 76 are embedded. The multi-core cable 70 and the shielded cable 75 are arranged side by side in a width direction intersecting with the arrangement direction (up-down direction) of the multi-core cable 70 and the shielded cable 75 in the arrangement space 12. The pressing member 40 has a partition wall 44 that separates the multi-core cable 70 and the shielded cable 75. Providing the partition wall 44 makes it possible to prevent the multi-core cable 70 and the shielded cable 75 from being arranged biased in the width direction (for example, toward the multi-core cable 70 side).

[0046] [Other Examples] The present invention is not limited to the embodiments described above and shown in the drawings, but is indicated by the claims. The present invention includes the meaning equivalent to the claims and all modifications within the scope of the claims, and is intended to include the following embodiments. The present invention can also be applied to cases where the terminal module is not connected to a differential pair line. The present invention can also be applied to a case where the power line and the earth line do not constitute a multi-core cable. The pressing member may not have a partition wall. A partition wall may be formed in the cover. The number of cables may be one or may be three or more. [Explanation of symbols]
