JP, 2016-41591, A

By the way, when the pulling force acts on the harness, the connector described in Patent Document 1 has a structure in which the force is mainly received by either the housing body or the cover. Therefore, when a strong tensile force is applied, the connection between the housing body and the cover is likely to be dislocated or dislocated.
Moreover, in the above-mentioned patent document 1, the connection part bears the end of the coupling | bonding with a housing main body and a cover. For this reason, for example, when the connection portion is broken due to aged deterioration, an external force, or the like, there is also a possibility that the cover may come off from the housing main body.

  Therefore, the present invention has been made in view of the above-mentioned circumstances, and it is possible to enhance the integral connection between two members sandwiching a harness, and a connector housing which is less likely to be disjointed or disjointed, and An object of the present invention is to provide a connector configured using the connector housing.

  In order to solve the above-mentioned subject, the connector housing concerning the present invention is a substrate which supports the conductor exposure part bent in U shape of the tip of a harness, when the direction in which a mating connector is fitted is made the front. A first plate having a front end edge on which the U-shaped bent portion of the conductor exposed portion is disposed, and a portion on the proximal side of the U-shaped bent portion of the conductor exposed portion along the front-rear direction Surface, a substrate having a second plate surface in which a portion on the tip side of the U-shaped bent portion of the conductor exposed portion is disposed along the front-rear direction, and one of the first plate surface and the second plate surface A harness guide provided on one plate surface and supporting the tip end portion or the base end portion of the exposed conductor portion disposed on the one plate surface as an electrical contact in conductive contact with the electrical contact of the mating connector Part of the first and second plate surfaces A cover for holding the harness between the board and the substrate, and a connecting means for connecting the board and the cover in a state of holding the harness and for releasing the connection. A front protrusion provided at a front end and a rear end of the cover and engaging the front end and the rear end of the substrate when the cover is coupled to the substrate, thereby positionally restricting the substrate in the front-rear direction; And a rear protrusion.

With this configuration, the exposed conductor portion supported by the harness guide portion on one plate surface of the substrate can function as an electrical contact in conductive contact with the electrical contact of the mating connector. Further, by connecting the cover to the substrate, the harness can be held between the substrate and the cover that is to be brought into contact with the other surface of the substrate.
For example, as the first example (the first embodiment), when the other plate surface is the first plate surface and one plate surface is the second plate surface, a U-shaped break of the conductor exposed portion at the tip of the harness Position the bend at the front edge. Further, a portion on the proximal side of the U-shaped bent portion of the conductor exposed portion is disposed on the first plate surface (the other plate surface) along the front-rear direction. Further, a portion on the tip side of the U-shaped bent portion of the conductor exposed portion is disposed on the second plate surface (one plate surface) along the front-rear direction. In this state, the cover is coupled to the substrate, and the cover is faced to the first plate surface (the other plate surface). Thereby, the base end side of the conductor exposed portion can be held between the first plate surface (the other plate surface) of the substrate and the cover. At the same time, by supporting the tip side of the conductor exposed portion by the harness guide portion on the second plate surface (one plate surface), the portion on the tip side of the conductor exposed portion is in conductive contact with the electrical contact of the mating connector It can function as an electrical contact.
On the other hand, when the other plate surface is the second plate surface and one plate surface is the first plate surface as the second example (the second embodiment), the U shape of the conductor exposed portion at the end of the harness is Position the bend at the front edge. Further, a portion on the proximal side of the U-shaped bent portion of the conductor exposed portion is disposed on the first plate surface (one plate surface) along the front-rear direction. Further, a portion on the tip side of the U-shaped bent portion of the conductor exposed portion is disposed on the second plate surface (the other plate surface) along the front-rear direction. In this state, the cover is coupled to the substrate, and the cover is faced to the second plate surface (the other plate surface), so that the conductor between the second plate surface (the other plate surface) of the substrate and the cover The tip side of the exposed portion can be held. At the same time, by supporting the base end side of the conductor exposed portion by the harness guide portion on the first plate surface (one plate surface), the base end portion of the conductor exposed portion is electrically connected to the electrical contact of the mating connector. It can function as a contacting electrical contact.
Further, when the cover is coupled to the substrate by the coupling means, the front projection of the cover is engaged with the front end of the substrate, and the rear projection of the cover is engaged with the rear end of the substrate. Accordingly, the cover can restrict the back and forth movement of the substrate, and the integral connection between the cover and the substrate can be enhanced. In addition, even when an external force in the front-rear direction is applied through the harness or the mating connector, it is possible to prevent the connection between the substrate and the cover from being shifted or the connection being disconnected.

  In the connector housing according to the present invention, a band plate-shaped insertion piece of the mating connector is formed by surrounding the four sides by the lower plate, the upper plate facing the lower plate, and the left and right side plates connecting the lower plate and the upper plate.

FIG. 10 is a side cross-sectional view showing a state in which the connector 2 whose electrical contact is completed inside the insertion hole 12 is completed and the insertion piece 201 of the mating connector 200 is to be inserted into the connector 2. FIG. 10 is a cross-sectional view corresponding to FIG.

  When assembling the connector 2, first, as shown in FIG. 3A, FIG. 5, and FIG. 7, insert the end Wa1 of the conductor exposed portion Wa of the harness W into the insertion hole 12 of the housing main body 10 from the front Do. At that time, the tip Wa1 of the conductor exposed portion Wa is bent downward in a hook shape, and the portion is hooked on the through hole 21 of the lower plate 11a of the housing main body 10 (operation of arrow S1 in FIGS. 5 and 7). Thereby, as shown in FIG. 8, the tip end side of the conductor exposed portion Wa can be disposed on the harness guide groove 23 on the basis of the portion hooked in the through hole 21.

  Next, in this state, as shown in FIG. 3B, FIG. 6, and FIG. 9, the middle portion of the conductor exposed portion Wa is bent downward while being fitted into the notch 24 provided in the front end edge KC of the lower plate 11a. Furthermore, with the front end edge KC of the lower plate 11a as a bending fulcrum, the middle portion of the conductor exposed portion Wa is further bent in a U shape (the operation of the arrow S2 in FIGS. 6 and 9).

  Under the present circumstances, since it becomes bending operation in the state which restrained front-end Wa1 of the conductor exposure part Wa to the through hole 21, it can bend stably easily. Further, the bending operation of the conductor exposed portion Wa can be performed while confirming the hooking state of the tip Wa1 of the conductor exposed portion Wa with respect to the through hole 21 through the window portion 15. In this bending, since the notches 24 are used for bending, the conductor exposed portion Wa can be bent at a stable position without lateral displacement.

  As shown in FIG. 6, the base end side of the conductor exposed portion Wa led to the lower surface KB side of the lower plate 11a after bending is in the harness support groove 26 of the harness support portion 25 provided on the lower surface KB side of the lower plate 11a. To accommodate. Further, the portion of the harness W with the cover Wb extending to the base end side of the harness W than the conductor exposed portion Wa is accommodated in the harness guide groove 22 in a state of being extended to the rear of the connector housing 1.

  In this state, as shown in FIGS. 3 (c) and 10, the hinge 60 (see FIGS. 1 and 2) is bent to make the main plate 51 of the cover 50 face the lower surface KB of the housing body 10 (FIG. 10). Arrow F)). Then, the engagement claws 56 of the cover 50 are engaged with the engagement claws 16 of the housing main body 10. By doing so, the harness W can be held between the lower surface KB of the lower plate 11 a of the housing body 10 and the main plate 51 of the cover 50.

By going through the above procedure, the connector 2 shown in FIG. 3 (c) and FIG. 10 is completed.
In this connector 2, the base end side of the conductor exposed portion Wa of the tip of the harness W introduced from the rear to the front is disposed on the lower surface KB (first surface) of the lower plate 11 a of the housing main body 10 Become. Also, the U-shaped bent portion of the conductor exposed portion Wa is disposed at the front end edge KC of the lower plate 11a. Further, the tip end side of the conductor exposed portion Wa is disposed on the upper surface KA (second plate surface) side of the lower plate 11a. In addition, the tip end side of the conductor exposed portion Wa is disposed in the harness guide groove 23 formed on the upper surface of the lower plate 11a, so that the electrical contact is brought into conductive contact with the electrical contact 202 on the lower surface of the insertion piece 201 of the mating connector 200. It will be configured as The harness W is also held between the housing body 10 and the cover 50.

  In addition, when the cover 50 is coupled to the housing main body 10 in this manner, the front frame portion 52 which is the front projection of the cover 50 engages with the front end of the housing main body 10, and the rear projection 53 of the cover 50 is the housing main body Engage with the back end of 10 Accordingly, the movement of the housing body 10 in the front-rear direction can be restricted by the cover 50, and the integral connection between the cover 50 and the housing body 10 can be enhanced.

  Further, since the bent portion of the conductor exposed portion Wa can be accommodated in the inside of the notch 24, the front end of the lower plate 11 a of the housing main body 10 can not be protruded by bending. Therefore, the front frame portion 52 of the cover 50 can be disposed in close contact with the front end surface of the box body 11 of the housing main body 10.

  For the connector 2 having the above configuration, as shown in FIGS. 4 and 10, the mating connector 200 passes through the opening 52a of the front frame portion 52 of the cover 50 and the receiving port 12a in the insertion hole 12 of the housing body 10. Insert piece 201 can be inserted (the operation of arrow M in FIG. 10). Then, the electric contact 202 on the lower surface of the inserted insertion piece 201 is brought into sliding contact with the conductor exposed portion Wa (electric contact) supported on the harness guide groove 23 of the lower plate 11 a of the insertion hole 12. it can. When the mating connector 200 is inserted, the distal end Wa1 of the conductor exposed portion Wa receives a frictional force in the direction in which it is pushed to the back side of the insertion hole 12. For this reason, the harness W does not easily come off the connector housing 1.

Further, since the mating connector 200 is fitted to the housing body 10 through the opening 52a of the front frame portion 52 of a size that covers the entire front end face of the housing body 10, the housing body 10, the cover 50 and the mating connector 200 are coupled Sex also increases. Therefore, even when an external force in the front-rear direction acts on the connector 2 through the harness W and the mating connector 200, it is possible to prevent the connection between the housing main body 10 and the cover 50 from being dislocated or disengaging.
Furthermore, since the front frame portion 52 and the mating connector 200 are fitted together, the cover 50 is additionally supported by the mating connector 200. Thus, the cover 50 can be reliably prevented from falling off the housing body 10.

  In the above description, when the end Wa1 of the conductor exposed portion Wa is inserted into the insertion hole 12 of the housing main body 10, the end Wa1 of the conductor exposed portion Wa is bent in a hook shape, I mentioned an example of hooking. However, it is not necessary to do so.

  FIG. 11 is a view for explaining another method of incorporating the conductor exposed portion Wa at the tip of the harness W into the housing main body 10, wherein the conductor exposed portion Wa at the tip of the harness W from the front to the insertion hole 12 of the housing body 10 It is a side sectional view showing a state where it is going to insert. 12 bends the middle part of the conductor exposed part Wa to the lower surface KB side of the housing main body 10 in a U shape next to the state of FIG. 11, extends the base end side of the harness W backward, and in that state the housing main body By connecting the cover 50 to 10, the base end side of the harness W is sandwiched between the housing main body 10 and the cover 50, and the tip end side of the conductor exposed portion Wa is used as an electrical contact inside the insertion hole 12. It is a sectional side view which shows the state which completes the connector 2 and it is going to insert the insertion piece 201 of the other party connector 200 with respect to the connector 2. FIG.

  As shown in FIG. 11, in this example, the tip Wa1 of the conductor exposed portion Wa is inserted into the back of the insertion hole 12 while the conductor exposed portion Wa of the harness W is placed on the harness guide groove 23 of the housing main body 10. Then, the front end Wa1 of the conductor exposed portion Wa in a non-bent state is abutted against the conical planar guide wall 28 of the rear wall 13 at the back of the insertion hole 12. As a result, the front end Wa1 of the conductor exposed portion Wa is held inside the conical planar guide wall 28, and the front end Wa1 of the conductor exposed portion Wa can be guided downward.

  In that state, the middle portion of the conductor exposed portion Wa is bent in a U-shape in the notch 24 with the front end edge KC of the lower plate 11a as a bending fulcrum. In this bending, the portion inserted inside the conical surface guide wall 28 is fixed to the conical surface guide wall 28, so that the tip Wa1 of the conductor exposed portion Wa does not float up by reaction due to the bending. Therefore, it can bend stably. In addition, the position of the end Wa1 of the conductor exposed portion Wa (a portion inserted inside the conical planar guide wall 28) may be confirmed from the upper side or the lower side of the housing main body 10 through the window portion 15 and the through hole 21. it can. Therefore, it is possible to prevent a bending failure due to a reaction at the time of bending, and to improve the accuracy of the position of the conductor exposed portion Wa disposed in the harness guide groove 23 and the position of the bending.

  After bending it into a U shape, arrange the harness W in the same manner as the previous example, bend the hinge 60 (see FIGS. 1 and 2), and align the main plate 51 of the cover 50 with the lower surface KB of the housing main body 10 Do. Then, by engaging the engagement claws 56 of the cover 50 with the engagement claws 16 of the housing main body 10, as shown in FIG. 12, the harness W is held between the housing main body 10 and the cover 50. Thereby, the connector 2 can be completed.

In the above description, the unexposed conductor exposed portion Wa is inserted into the housing main body 10, and the middle portion of the conductor exposed portion Wa is formed into a U shape using the front end edge KC of the lower plate 11a. I mentioned the case of bending.
However, the conductor exposed portion Wa may not necessarily be bent in a U-shape after being introduced into the housing main body 10. That is, the conductor exposed portion Wa may be previously bent in a U shape, and the conductor exposed portion Wa in a state of being bent in the U shape may be incorporated into the housing body 10. In that case, a U-shaped bent portion is disposed at the front end edge KC of the housing main body 10, and the tip end side of the U-shaped bent portion of the conductor exposed portion Wa is inserted into the insertion hole 12 and the lower plate 11a It arrange | positions in the harness guide groove 23 by the side of upper surface KA. Further, the base end side of the U-shaped bent portion of the conductor exposed portion Wa is disposed in the harness support groove 26 of the lower surface KB of the lower plate 11a of the housing body 10, and the harness W of the portion with the cover Wb is harnessed Arranged in the groove 22. The subsequent procedure is the same as that described above.

Further, in the above description, the end Wa1 side of the conductor exposed portion Wa of the harness W is disposed on the upper surface KA of the lower plate 11a of the housing main body 10, and the U shape of the conductor exposed portion Wa on the lower surface KB of the lower plate 11a. The case where the part of the proximal end side from the bent part of the shape was arrange | positioned was demonstrated.
However, as shown in FIG. 13, the housing main body 10 is disposed on the upper surface KA of the lower plate 11 a and a portion of the conductor exposed portion Wa of the harness W proximal to the U-shaped bent portion. The lower end KB may be configured to dispose the tip end Wa1 side of the conductor exposed portion Wa of the harness W.

A harness guide groove (harness guide portion) 123 on which the tip end side of the conductor exposed portion Wa is placed is provided on the upper surface of the harness holding convex portion 120. The proximal end side of the exposed conductor portion Wa can be used as an electrical contact by arranging the proximal end side (the proximal end side from the U-shaped bent portion) of the exposed conductor portion Wa in the harness guide groove 123. it can.

  The front edge of the harness guide groove 123 is a V-shaped or U-shaped notch as viewed from above, which serves as a fulcrum for guiding the bending when bending the middle portion of the conductor exposed portion Wa in a U-shape 124 are provided. Further, the rear wall 113 for closing the rear end of the box body 111 is provided with two insertion holes 121 for inserting the conductor exposed portion Wa from the rear. These insertion holes 121 are located on the extension of the harness guide groove 123 so that the conductor exposed portion Wa introduced from the insertion hole 121 can be placed on the harness guide groove 123 as it is.

  Further, on the lower surface of the housing main body 110, that is, the lower surface KB of the lower plate 111a, two harness support grooves 126 are provided corresponding to the two harness guide grooves 123 of the upper surface KA of the lower plate 111a. The harness support groove 126 extends rearward from the front end edge of the lower plate 111a, and its end is a dead end.

  The lower surface KB of the housing main body 110 is a plate surface that faces the cover 150. The cover 150 has a main plate 151 provided with a plate surface that faces the lower surface KB of the housing body 110. The plate surface seen above in FIG. 14 is the mating surface of the main plate 151. The tip end side of the conductor exposed portion Wa is sandwiched between the plate surface and the lower surface KB of the housing main body 110. Two harness support grooves 154 are provided on the mating surface of the cover 150 so as to correspond to the harness support grooves 126 on the lower surface of the housing body 110. The harness support grooves 154 also extend rearward from the front end edge of the main plate 151, and the end is a dead end.

  At both end portions in the left-right direction of the main plate 151, engaging claws 156 (coupling means) are provided which elastically engage with the engaging claws 116 on the housing main body 110 side when the main plate 151 is aligned with the housing main body 110. When the engaging claws 116 and 156 face each other in a state in which the housing body 110 and the cover 150 are sandwiched between the housing body 110 and the cover 150, they engage with each other to integrally couple the housing body 110 and the cover 50. Further, by disengaging the engagement claw 116 on the housing body 110 side and the engagement claw 156 on the cover 150 side, the connection between the housing body 110 and the cover 150 can be released.

  A front frame portion 152 is provided at the front end of the cover 150 as a front projection.

Next, the assembly procedure of the connector using the connector housing 101 of the said structure is demonstrated.
FIG. 16 is a perspective view showing a state where the conductor exposed portion Wa at the tip of the harness W is about to be inserted from the rear into the insertion hole 121 provided in the rear wall 113 of the housing body 110 of the connector housing 101. FIG. 17 is a perspective view showing a state in which the distal end side of the conductor exposed portion Wa inserted into the housing main body 110 next to the state of FIG. 16 is about to be bent in a U shape toward the lower surface side of the housing main body 110.

  When assembling the connector using this connector housing 101, first, as shown in FIG. 16, the end Wa1 of the conductor exposed portion Wa of the harness W is different from the insertion hole 121 provided in the rear wall 113 of the connector housing 101. It inserts in the insertion hole 112 (operation | movement of arrow S1). The base end side of the inserted conductor exposed portion Wa is placed on the harness guide groove 123 as shown in FIG. Then, the front end side of the conductor exposed portion Wa protruding from the harness guide groove 123 is bent downward while accommodating the middle portion in the notch 124 and is bent in a U shape along the lower surface KB of the housing main body 110 (arrow Operation of S2). Under the present circumstances, since the base end side of the conductor exposure part Wa is hold | maintained and fixed by the penetration hole 121, it can bend stably easily. Then, the tip end side of the conductor exposed portion Wa is disposed in the harness support groove 126 of the lower surface KB of the housing main body 110.

  In this state, the main plate 151 of the cover 150 is made to face the lower surface KB of the housing main body 10 (operation indicated by arrow F in FIG. 17). Then, the engagement claws 156 of the cover 150 are engaged with the engagement claws 116 of the housing body 110. By doing so, the tip end side of the conductor exposed portion Wa of the harness W can be held between the lower surface KB of the lower plate 111 a of the housing body 110 and the main plate 151 of the cover 150.

  The connector can be completed through the above procedure. In this connector, the base end side of the conductor exposed portion Wa of the tip of the harness W introduced from the rear to the front is disposed on the upper surface KA (first plate surface) of the lower plate 111 a of the housing body 110. Further, a U-shaped bent portion of the conductor exposed portion Wa is disposed at the front end edge KC of the lower plate 111a. Further, the tip end side of the conductor exposed portion Wa is disposed on the lower surface KB (second plate surface) of the lower plate 111a. Then, the base end side of the conductor exposed portion Wa is disposed in the harness guide groove 123 formed on the upper surface of the lower plate 111a, thereby making electrical contact with the electric contact 202 on the lower surface of the insertion piece 201 of the mating connector 200 conductively. It will be configured as Further, the tip end side of the conductor exposed portion Wa is sandwiched between the housing main body 110 and the cover 150.

  Also, when the cover 150 is coupled to the housing body 110 in this manner, the front frame portion 152 which is the front projection of the cover 150 engages with the front end of the housing body 110, and the rear projection 153 of the cover 150 is the housing body. Engage the rear end of 110. Therefore, the movement of the housing body 110 in the front-rear direction can be restricted by the cover 150, and the integral connection between the cover 150 and the housing body 110 can be enhanced.

  Further, since the bent portion of the conductor exposed portion Wa can be accommodated inside the notch 124, the front end of the lower plate 111a of the housing main body 110 can not be protruded by bending. Therefore, the front frame portion 152 of the cover 150 can be disposed in close contact with the front end surface of the box 111 of the housing body 110.

  With respect to the connector having the above configuration, as in the first embodiment, the insertion piece of the mating connector 200 through the opening 152a of the front frame portion 152 of the cover 150 and the reception port 112a in the insertion hole 112 of the housing body 110 201 can be inserted. Then, the electric contact 202 on the lower surface of the inserted insertion piece 201 is brought into sliding contact with the conductor exposed portion Wa (electric contact) supported on the harness guide groove 123 of the lower plate 111 a of the insertion hole 112. it can.

  Also, since the mating connector 200 is fitted to the housing body 110 through the opening 152a of the front frame portion 152 of a size that covers the entire front end face of the housing body 110, the housing body 110, the cover 150 and the mating connector 200 are coupled Sex also increases. Therefore, even when an external force in the front-rear direction acts on the connector via the harness W or the mating connector 200, it is possible to prevent the connection between the housing body 110 and the cover 150 from being shifted or the connection being disconnected.

  By the way, when the conductor exposed portion Wa is bent in a U-shape, the conductor exposed portion Wa can be pressed and bent by the cover 150. In that case, the distal end side of the conductor exposed portion Wa can be held between the housing main body 110 and the cover 150 by connecting the cover 150 to the housing main body 110 as it is.

  The present invention is not limited to the above-described embodiment, and includes the above-described embodiment with various modifications, without departing from the spirit of the present invention.

  For example, although the case where the number of harnesses W introduced into the connector housings 1 and 101 is two in the above embodiment, the number of harnesses introduced may be one or three or more. Accordingly, the number of portions supporting the conductor exposed portion may be changed.
