[Description of Embodiments of the Present Disclosure]
First, the embodiments of the present disclosure will be listed and described.
The connector of the present disclosure is
(1) A housing having a module storage chamber and a wiring space, and a terminal module having terminal fittings connected to electric wires and inserted into the module storage chamber, wherein the housing includes the module storage chamber and the wiring space. and a cover that opens and closes an opening of the wiring space on the outer surface of the housing body by rotating about a hinge. When the opening is closed, the electric wire drawn out from the module housing chamber into the wiring space is sandwiched between the protrusion of the cover and a receiving portion in the wiring space and bent. and the cover rotates in the direction of closing the opening, the protrusion is displaced in the wiring space in the direction of approaching the module storage chamber. According to the configuration of the present disclosure, the strain relief portion is formed by the receiving portion of the housing main body and the protrusion of the cover. There is no tensile force on the connection part of During the process in which the cover closes the opening of the wiring space, the projecting portion presses the part of the electric wire, which is laid in the wiring space, toward the module housing chamber. No tensile force acts. Therefore, it is possible to suppress damage to the connecting portion between the electric wire and the terminal fitting.

(2) The electric wire includes two signal wires forming a differential pair wire, and the differential pair wire forms one shielded cable by being embedded in a sheath in a twisted state. , It is preferable that a portion of the differential pair wire embedded in the sheath is bent while being sandwiched between the protrusion and the receiving portion. According to this configuration, the untwisted length of the differential pair lines can be shortened, so the communication performance is excellent. Since the portion of the differential pair wire exposed from the sheath has low rigidity, it is likely to be misaligned in the axial direction even if it is sandwiched between the protrusion and the receiving portion. On the other hand, since the portion of the shielded cable where the differential pair wires are embedded in the sheath has higher rigidity than the exposed portion of the differential pair wires, it is sandwiched between the projecting portion and the receiving portion, causing the axial direction to move. Displacement is less likely to occur.

(3) The electric wire includes a power wire and a ground wire, and the power wire and the ground wire constitute one multi-core cable by being embedded in an insulating coating, and the power wire and the ground wire. It is preferable that a part embedded in the insulating coating is sandwiched and bent between the protrusion and the receiving part. The portions of the power wire and the ground wire exposed from the insulating coating have low rigidity, and thus are likely to be misaligned in the axial direction even if they are sandwiched between the protrusion and the receiving portion. On the other hand, the portion of the multi-core cable in which the power wire and the ground wire are embedded in the insulating coating has a higher rigidity than the exposed portion of the power wire and the ground wire, so it cannot be caught between the protrusion and the receiving portion. Due to this, positional deviation in the axial direction is less likely to occur.

[Details of the embodiment of the present disclosure]
[Example 1]
A first embodiment embodying the present disclosure will be described with reference to FIGS. 1 to 7. FIG. The present invention is not limited to these examples, but is indicated by the scope of the claims, and is intended to include all modifications within the scope and meaning equivalent to the scope of the claims. In the first embodiment, regarding the front-rear direction, the positive direction of the X-axis in FIGS. 1 to 7 is defined as the front. Regarding the left-right direction, the positive direction of the Y-axis in FIGS. 1 and 2 is defined as right. Regarding the vertical direction, the positive direction of the Z-axis in FIGS. 1 to 7 is defined as upward. As shown in FIG. 2, the connector of Example 1 is constructed by assembling a housing 10, a rubber plug 40, a holder 45, and a terminal module 50. As shown in FIG.

The housing 10 is a single component made of synthetic resin having a housing body portion 11 , a cover 30 and a hinge portion 37 . As shown in FIGS. 2 to 7, a wiring space 12 is formed inside the housing body portion 11 . A rear surface opening 13 that communicates with the wiring space 12 is formed on the rear surface of the outer surface of the housing main body portion 11 . The opening shape of the rear surface opening 13 is a vertically long rectangle. A lower surface opening 14 that communicates with the cabling space 12 is formed in the lower surface of the outer surface of the housing main body 11 that is perpendicular to the rear surface. A module receiving chamber 15 is formed at the upper end of the housing main body 11 so as to pass through the housing main body 11 in the front-rear direction. A front end of the module storage chamber 15 opens to the front surface of the housing main body 11 . The rear end of the module storage chamber 15 communicates with the upper end space of the wiring space 12 and is exposed to the outside of the housing body 11 at the rear opening 13 .

An upper receiving portion 17 is formed in the upper end region of the front wall portion 16 forming the cabling space 12 . The upper receiving portion 17 has a first protrusion 18 and a second protrusion 19 . The first projection 18 faces the cabling space 12 and protrudes obliquely downward from the rear surface of the front wall portion 16 . The second projection 19 faces the wiring space 12 and protrudes obliquely downward from the rear surface of the front wall portion 16 . The second projection 19 is located below the first projection 18 and located behind the first projection 18 . In a side view of the housing main body 11 from the side, a region of the rear surface of the front wall portion 16 where the upper receiving portion 17 is formed is inclined in an overhang shape so as to be lowered forward. .

A lower receiving portion 20 is formed in a lower end region of the rear surface of the front wall portion 16 (a region below the upper receiving portion 17). The lower receiving part 20 protrudes rearward so as to advance into the cabling space 12 . In the upper end region of the front surface of the lower receiving portion 20, a receiving surface 21 is formed on the side surface so as to gradually decrease toward the rear. A concave portion 22 is formed between the upper receiving portion 17 and the lower receiving portion 20 on the rear surface of the front wall portion 16 so as to be concave forward with respect to the upper receiving portion 17 and the lower receiving portion 20 . .

As shown in FIG. 2 , a pair of locking portions 23 are formed on the inner surfaces of the left and right side wall portions forming the cabling space 12 . The front end portion of the locking portion 23 has a stepped shape that forms a locking surface (not shown) facing forward (the side opposite to the rear opening portion 13 in the front-rear direction). Guide portions 24 are formed on inner surfaces of both locking portions 23 facing each other. The guide portion 24 is inclined so as to gradually become shallower toward the front. A pair of lock projections 25 are formed on both left and right outer surfaces of the housing main body 11 .

As shown in FIG. 2 , the cover 30 has a rectangular plate-like covering portion 31 , one protrusion 32 and a pair of elastic locking pieces 35 . The plate-shaped cover portion 31 has a size that covers the rear opening portion 13 . The plate-shaped cover portion 31 is connected to the housing main body portion 11 via a hinge portion 37 along the upper edge of the opening edge of the rear opening portion 13 . The cover 30 is rotatable at an angle of 90° between the open position (see FIG. 3) and the closed position (see FIGS. 1, 6 and 7) with the hinge portion 37 (horizontal axis) as a fulcrum. It's becoming At the open position, the cover 30 is positioned behind the housing main body 11 , and the wiring space 12 and the module storage chamber 15 are opened to the outside of the housing 10 through the rear surface opening 13 . The plate-shaped cover portion 31 extends rearward from the housing main body portion 11 with the plate thickness direction facing the vertical direction. At the closed position, the plate-shaped cover portion 31 closes the rear opening 13 and the protrusion 32 is arranged in the cabling space 12 .

As shown in FIGS. 3 to 7, the protrusion 32 protrudes forward from a lower end region on the front surface of the plate-like cover portion 31 . When viewed from the side, the projection 32 has a triangular shape. When the cover 30 is in the closed position, the upper surface of the protrusion 32 (upper end region on the front surface) forms an upper pressing surface 33 that slopes down toward the front. The lower surface of the protrusion 32 (lower end region on the front surface) is a lower pressing surface 34 that slopes upward toward the front. As shown in FIG. 2 , the elastic locking piece 35 has a cantilevered shape extending from the lower ends of the left and right side edges of the plate-shaped cover portion 31 . A locking projection 36 is formed at the front end of the elastic locking piece 35 . The elastic locking piece 35 can be elastically deformed in the left-right direction.

In the process of rotating the cover 30 from the open position to the closed position, the elastic locking pieces 35 are elastically deformed by the locking protrusions 36 coming into sliding contact with the guide portions 24 . When the cover 30 reaches the closed position, the plate-shaped cover portion 31 closes the entire area of the rear opening 13 . The elastic locking piece 35 is elastically restored, and the locking projection 36 locks the front end portion of the locking portion 23 from the front. This engagement holds the cover 30 attached to the housing main body 11 at the closed position.

The hinge portion 37 is positioned at the upper end of the rear opening 13, the module housing chamber 15 is positioned in front of the hinge portion 37, and the cover 30 rotates about the hinge portion 37 as a fulcrum. Therefore, in the process of rotating the cover 30 from the open position to the closed position, the protruding end 32P of the protrusion 32 is displaced obliquely downward and forward until it reaches the rear opening 13. After passing through 13 and entering the wiring space 12, it is displaced obliquely upward and forward to draw an arc. At this time, the trajectory of the movement of the projecting end 32P of the protrusion 32 is the wiring direction of the multi-core cable 60 (the power line 61 and the ground line 62) and the shielded cable 65 (the signal line 66) in the wiring space 12. The vertical direction is the direction approaching the module housing chamber 15 .

When the cover 30 is held in the closed position, the upper end region of the upper pressing surface 33 of the protrusion 32 and the upper receiving portion 17 are positioned to face each other in the front-rear direction at the same height. When viewed from the side, the upper pressing surface 33 is parallel to an imaginary line connecting the rearward projecting end 32P of the first projection 18 and the rearward projecting end 32P of the second projection 19 . The lower end side region of the upper pressing surface 33 and the protruding end 32P of the protrusion 32 are arranged at the same height as the recess 22 . The lower pressing surface 34 of the projecting portion 32 and the receiving surface 21 of the lower receiving portion 20 are at the same height and face each other in the front-rear direction. When the cover 30 is in the closed position, the lower receiving portion 20 and the receiving surface 21 are located forward of the projecting end 32P of the projecting portion 32. As shown in FIG. The receiving surface 21 and the lower pressing surface 34 of the cover 30 have the same height and are opposed to each other in the front-rear direction. In a side view, the receiving surface 21 and the lower pressing surface 34 are parallel.

The rubber plug 40 is a single component having a pair of left and right seal holes 41 . The seal hole 41 vertically penetrates the rubber plug 40 . A lip portion 42 is formed on the outer peripheral surface of the rubber plug 40 . The holder 45 is a single component having a plate-shaped pressing portion 46 and a pair of left and right lock arms 47 . The plate-shaped pressing portion 46 is a portion whose plate thickness direction is oriented in the vertical direction. A pair of left and right cable insertion holes 48 are formed in the plate-shaped pressing portion 46 . The pair of lock arms 47 are cantilevered upward from the left and right side edges of the plate-like pressing portion 46 .

The terminal module 50 has a synthetic resin case 51 and two pairs of terminal fittings 52 housed in the case 51 . As shown in FIG. 3, the two pairs of terminal fittings 52 are accommodated in two upper and lower stages. The terminal fitting 52 is a single component having a rectangular tube-shaped terminal body portion 53 and a crimping portion 54 connected to the rear end of the terminal body portion 53 .

A power wire 61 (see FIG. 2) made of a covered wire is connected to the crimping portion 54 of one of the two terminal fittings 52 housed in the upper side of the case 51 . A ground wire 62 (see FIG. 2) made of a covered wire is connected to the crimp portion 54 of the other terminal fitting 52 . The power line 61 and ground line 62 are embedded in a common insulating coating 63 . A single multi-core cable 60 is composed of the power wire 61 , the ground wire 62 and the insulating coating 63 . The cross-sectional shape of the multicore cable 60 (insulating coating 63) is circular. The end of the multicore cable 60 connected to the terminal fitting 52 constitutes the terminal module 50 .

Signal wires 66 (see FIG. 2) made of coated wires are connected to the crimping portions 54 of the two terminal fittings 52 housed in the lower side of the case 51, respectively. Two signal lines 66 constitute a differential pair line 68 . The differential pair wires 68 are embedded in a common sheath 67 in a twisted state. A differential pair line 68 constitutes a twisted pair line. A single shielded cable 65 is composed of the differential pair wire 68 and the sheath 67 . The cross-sectional shape of the shielded cable 65 (sheath 67) is circular. The end of the shielded cable 65 connected to the terminal fitting 52 constitutes the terminal module 50 .

In the terminal module 50 , the end of the insulating coating 63 and the end of the sheath 67 are located near the case 51 . In other words, the length of the power wire 61 and the ground wire 62 exposed from the insulating coating 63 is set to the minimum length necessary for attaching the terminal fitting 52 to the case 51 . The length of the signal wire 66 that is exposed from the insulating coating 63 is set to the minimum length necessary for attaching the terminal fitting 52 to the case 51 .

The rubber plug 40 and the holder 45 are attached to the multicore cable 60 and the shielded cable 65 before the terminal module 50 is attached to the housing body 11 . The multicore cable 60 and the shielded cable 65 are inserted through the seal hole 41 of the rubber plug 40 and the cable insertion hole 48 of the holder 45 . The rubber plug 40 is arranged at a position closer to the terminal fitting 52 than the holder 45 is.

Next, a connector assembly procedure will be described. With the cover 30 at the open position, the terminal module 50 is inserted into the wiring space 12 through the opening 14 on the lower surface and pulled out from the rear opening 13 to the outside of the housing main body 11 . The pulled-out terminal module 50 is inserted into the module storage chamber 15 through the rear opening 13 (see FIG. 3). The terminal module 50 inserted into the module receiving chamber 15 is retained by a retaining portion (not shown) provided in the housing body portion 11 .

The upper end of the insulating coating 63 of the multicore cable 60 and the upper end of the sheath 67 of the shielded cable 65 are located at approximately the same height as the first projection 18 . The portion of the multi-core cable 60 where the power line 61 and the ground line 62 are exposed has lower rigidity than the portion embedded in the insulating coating 63, so it bends with a relatively large curvature, and the wiring space 12 placed inside. A region of the power line 61 and the ground line 62 buried in the insulating coating 63 is also laid in the wiring space 12 . The portion of the shielded cable 65 where the signal line 66 is exposed has lower rigidity than the portion embedded in the sheath 67, so it is bent with a relatively large curvature and arranged in the cabling space 12. . A region of the signal line 66 embedded in the sheath 67 is also routed within the routing space 12 .

After the terminal module 50 is attached, the cover 30 is rotated from the open position to the closed position and assembled to the housing main body 11 . In the process of rotating the cover 30, the protruding end 32P of the protruding portion 32 reaches the rear opening portion 13 (see FIG. 4), and then the protruding end 32P of the protruding portion 32 reaches the insulating coating 63 in the cabling space 12. and the sheath 67 (see FIG. 5), pushing the multicore cable 60 and the shielded cable 65 forward. At this time, since the power line 61, the ground line 62, and the signal line 66, which have relatively low rigidity, are flexibly bent and deformed, the connecting portions between the power line 61 and the terminal fittings 52 and the connecting portions between the ground wire 62 and the terminal fittings 52 are bent. , a large load (tensile force) does not act on the connection portion between the signal line 66 and the terminal fitting 52 .

In the cabling space 12, the projecting end 32P of the projecting portion 32 draws an arcuate trajectory obliquely upward and forward. Therefore, while the protruding end 32P of the protrusion 32 pushes the multicore cable 60 and the shielded cable 65, the multicore cable 60 and the shielded cable 65 are pressed obliquely upward and forward. Therefore, the connecting portion between the crimping portion 54 of the terminal fitting 52 and the power wire 61, the connecting portion between the crimping portion 54 of the terminal fitting 52 and the ground wire 62, and the connecting portion between the crimping portion 54 of the terminal fitting 52 and the signal line 66 There is no tensile force acting on

When the cover 30 reaches the closed position, as shown in FIG. 6, the insulating coating 63 of the multicore cable 60 and the sheath 67 of the shielded cable 65 are connected to the upper pressing surface 33 and the upper receiving portion 17 (the first projection 18 and the second projection 18). It is sandwiched in the front-rear direction between the protrusion 19) and receives a forward pressing force from the projecting end 32P of the protrusion 32. Below the projecting end 32P of the projecting portion 32, the multicore cable 60 and the shielded cable 65 are pressed against the lower edge of the receiving surface 21 of the lower receiving portion 20 and receive a rearward reaction force. Among the multi-core cable 60 and the shielded cable 65, the inclination direction of the portion sandwiched between the upper pressing surface 33 and the upper receiving portion 17 and the portion sandwiched between the lower pressing surface 34 and the receiving surface 21 The direction of the inclination of the portion where the As a result, the portions of the multicore cable 60 and the shielded cable 65 that are pushed by the projecting end 32P of the projecting portion 32 are bent in a side view.

After assembling the cover 30 to the closed position, the rubber plug 40 and the holder 45 are slid upward, and the lock arm 47 of the holder 45 is engaged with the lock projection 25 of the housing body 11 . As a result, the rubber plug 40 and the holder 45 are held attached to the housing body 11 . By the above, assembly of the connector is completed.

When the multicore cable 60 and the shielded cable 65 are pulled downward on the lower outside of the connector, the insulation coating 63 of the multicore cable 60 and the sheath 67 of the shielded cable 65 are pulled from the lower edge of the receiving surface 21 of the lower receiving portion 20 . and the projecting end 32P of the protrusion 32 (the lower edge of the upper pressing surface 33). These catches restrict downward movement of the multicore cable 60 and the shielded cable 65 . Therefore, a tensile load does not act on the connecting portion between the terminal fitting 52 and the power line 61, the connecting portion between the terminal fitting 52 and the ground wire 62, and the connecting portion between the terminal fitting 52 and the signal line 66. FIG.

The connector of Example 1 includes a housing 10 and a terminal module 50 . The housing 10 has a module storage chamber 15 and a wiring space 12 . Housing 10 is a single piece having housing body 11 and cover 30 . A module storage chamber 15 and a wiring space 12 are formed in the housing body portion 11 . The cover 30 opens and closes the opening (rear surface opening 13 ) of the wiring space 12 on the outer surface of the housing main body 11 by rotating about the hinge portion 37 . The terminal module 50 has terminal fittings 52 connected to electric wires 61 , 62 , 66 and is inserted into the module housing chamber 15 .

When the cover 30 closes the rear opening 13 , the electric wires 61 , 62 , 66 (the multicore cable 60 and the shielded cable 65 ) drawn out from the module housing chamber 15 into the wiring space 12 are projected from the cover 30 . It is sandwiched between the portion 32 and the upper receiving portion 17 and the lower receiving portion 20 in the cabling space 12 and laid in a bent state. In the process of rotating the cover 30 in the direction to close the rear opening 13 , the protrusion 32 is displaced in the wiring space 12 in the direction to approach the module storage chamber 15 .

According to this configuration, the upper receiving portion 17 and the lower receiving portion 20 of the housing main body 11 and the protrusions 32 of the cover 30 constitute the strain relief portion 69 , so that the outer lower portion of the housing 10 is multi-core. Even if a tensile force acts on the cable 60 and the shielded cable 65 (electric wires 61 , 62 , 66 ), the tensile force does not reach the connecting portion between the electric wires 61 , 62 , 66 and the terminal fitting 52 . When the cover 30 closes the rear opening 13 of the wiring space 12 , the protrusion 32 is routed in the wiring space 12 among the multicore cable 60 and the shielded cable 65 (electric wires 61 , 62 , 66 ). Since the portion where the wire is attached is pressed toward the module housing chamber 15 (diagonally upward and forward), no tensile force acts between the wires 61 , 62 , 66 and the terminal fitting 52 . Therefore, damage to the connecting portions between the electric wires 61, 62, 66 and the terminal fittings 52 can be suppressed.

The electric wires 61 , 62 , 66 include two signal wires 66 forming a differential pair wire 68 . The differential pair wires 68 (two signal wires 66) constitute one shielded cable 65 by being embedded in the sheath 67 in a twisted state. A portion of the differential pair wire 68 embedded in the sheath 67 is sandwiched and bent between the protrusion 32 of the cover 30 and the upper receiving portion 17 and the lower receiving portion 20 of the housing body portion 11 . . According to this configuration, the untwisted length (length exposed from the sheath 67) of the differential pair wires 68 can be shortened, so that the communication performance is excellent. Since the portion of the differential pair wire 68 exposed from the sheath 67 has a low rigidity, even if it is sandwiched between the protrusion 32 and the upper and lower receiving portions 17 and 20, the position in the axial direction (up and down direction) is maintained. Misalignment is likely to occur. On the other hand, the portion of the shielded cable 65 where the differential pair wires 68 are embedded in the sheath 67 has higher rigidity than the exposed portion of the differential pair wires 68. By being sandwiched between the portion 20 and the portion 20, it is difficult to cause misalignment in the axial direction.

Electric wires 61 , 62 , 66 include a power wire 61 and a ground wire 62 . The power wire 61 and the ground wire 62 constitute one multicore cable 60 by being embedded in an insulating coating 63 having the same diameter as the sheath 67 . The shielded cable 65 and the multicore cable 60 are arranged side by side in the width direction (horizontal direction). Portions of the power wire 61 and the ground wire 62 embedded in the insulating coating 63 are sandwiched between the protrusion 32 of the cover 30 and the upper receiving portion 17 and the lower receiving portion 20 of the housing main body 11 and bent. It is Since the portions of the power supply wire 61 and the ground wire 62 exposed from the insulating coating 63 have low rigidity, even if they are sandwiched between the protrusion 32 and the upper receiving portion 17 and the lower receiving portion 20, they may ) is likely to be misaligned. On the other hand, since the portion of the multi-core cable 60 where the power line 61 and the ground line 62 are embedded in the insulating coating 63 has higher rigidity than the exposed portions of the power line 61 and the ground line 62, the protrusion 32 and the upper receiving part are in contact with each other. Being sandwiched between the portion 17 and the lower receiving portion 20 makes it difficult for axial displacement to occur.
