Description

Connector housing and connector

Technical Field

The present invention relates to a connector housing for constituting a connector in which a conductor exposed portion at a front end of a wire harness is directly used as an electrical contact, and a connector constituted using the connector housing.

Background

A connector in which a conductor exposed portion at a tip of a wire harness (electric wire) is directly used as an electric contact is known. This connector can omit the terminal fitting, and thus can be made simple. Therefore, for example, the connector is used to connect a power supply terminal of a hub dynamo (hubdynamo) of a bicycle to a lamp.

As such a connector, patent document 1 discloses a connector including: a case body (first case portion), a cover (second case portion), and a connecting portion connecting the case body and the cover. The connector is disclosed with a connector in which the connection portion is bent by about 90 degrees to combine the housing body and the cover with each other, thereby holding the wire harness therebetween. The connecting portion serves as one end of the combination of the housing body and the cover.

In such a connector, the intermediate portion of the conductor exposure portion at the front end of the wire harness is bent into a U shape at the front end edge of the substrate to prevent the wire harness from coming off, and a part of the conductor exposure portion is used as an electrical contact for making electrical conduction contact with an electrical contact of the mating connector.

Disclosure of Invention

Problems to be solved by the invention

Further, the connector described in patent document 1 is a structure in which when a tensile force has been applied to the wire harness, the force is received mainly by either the housing body or the cover. Therefore, when a strong tensile force acts, the coupling between the case body and the cover is likely to be deviated or the coupling is likely to be detached.

In patent document 1, the connecting portion serves as one end of the coupling between the housing body and the cover. Therefore, for example, if the connection portion is damaged by aged deterioration or external force, the cover may be detached from the housing main body.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a connector housing which can improve the integral bonding property of two members for sandwiching a wire harness and which is less likely to cause the bonding to be deviated or the bonding to be detached, and a connector configured using the connector housing.

Means for solving the problems

In order to solve the problem, the connector housing of the present invention includes: a substrate that supports a conductor exposure portion bent in a U shape of a front end of a wire harness when a direction in which a mating connector is fitted is set to a front side, and that has a front end edge of a U-shaped bent portion on which the conductor exposure portion is disposed, a first plate surface on which a portion of the conductor exposure portion closer to a base end side than the U-shaped bent portion is disposed along a front-rear direction, and a second plate surface on which a portion of the conductor exposure portion closer to a front end side than the U-shaped bent portion is disposed along the front-rear direction; a harness guide portion provided on one of the first plate surface and the second plate surface, the harness guide portion supporting a portion of the one plate surface, which is disposed on a distal end side or a proximal end side of the conductor exposure portion, as an electrical contact for making conductive contact with an electrical contact of a mating connector; a cover that is surface-bonded to the other of the first plate surface and the second plate surface, and that sandwiches the wire harness with the substrate; a coupling member that couples and decouples the substrate and the cover in a state where the wire harness is held; and front and rear protruding pieces provided at front and rear ends of the cover and engaged with front and rear ends of the substrate when the cover is coupled to the substrate, respectively, thereby restricting the position of the substrate in the front-rear direction.

With the above configuration, the conductor exposure portion supported by the harness guide portion on the one plate surface of the board can function as an electrical contact for making electrical contact with an electrical contact of the mating connector. Further, by coupling the cover to the substrate, the wire harness can be sandwiched between the cover surface-bonded to the other plate surface of the substrate and the substrate.

For example, as a first example (first embodiment), when the other plate surface is a first plate surface and one plate surface is a second plate surface, a U-shaped bent portion of a conductor exposed portion at the distal end of a wire harness is arranged at the distal end edge. Further, a portion of the conductor exposed portion closer to the base end side than the U-shaped bent portion is arranged on the first plate surface (the other plate surface) in the front-rear direction. Further, a portion of the conductor exposed portion on the distal end side of the U-shaped bent portion is arranged on a second plate surface (one plate surface) in the front-rear direction. In this state, the cover is bonded to the substrate, and the cover surface is bonded to the first plate surface (the other plate surface). Thus, the base end side of the conductor exposure portion can be sandwiched between the first plate surface (the other plate surface) of the substrate and the cover. At the same time, the distal end side of the conductor exposure portion is supported by the harness guide portion on the second plate surface (one plate surface), whereby the distal end side portion of the conductor exposure portion can function as an electrical contact for making conductive contact with an electrical contact of the mating connector.

In contrast, as a second example (second embodiment), when the other plate surface is a second plate surface and one plate surface is a first plate surface, the U-shaped bent portion of the conductor exposed portion at the distal end of the wire harness is arranged at the distal end edge. Further, a portion of the conductor exposed portion closer to the base end side than the U-shaped bent portion is arranged on the first plate surface (one plate surface) in the front-rear direction. Further, a portion of the conductor exposed portion on the distal end side of the U-shaped bent portion is arranged on the second plate surface (the other plate surface) in the front-rear direction. In this state, the cover is joined to the substrate, and the cover surface is joined to the second plate surface (the other plate surface), whereby the distal end side of the conductor exposure portion can be sandwiched between the second plate surface (the other plate surface) of the substrate and the cover. At the same time, the base end side of the conductor exposure portion is supported by the harness guide portion on the first plate surface (one plate surface), whereby the base end side portion of the conductor exposure portion can function as an electrical contact for making conductive contact with an electrical contact of the mating connector.

When the cover is coupled to the substrate by the coupling member as described above, the front protruding piece of the cover is engaged with the front end of the substrate, and the rear protruding piece of the cover is engaged with the rear end of the substrate. Therefore, the movement of the substrate in the front-rear direction can be restricted by the cover, and the integral bonding property of the cover and the substrate can be improved. Further, even when external force in the front-rear direction acts via the harness or the mating connector, the substrate and the cover can be prevented from being misaligned or disengaged.

The connector housing of the present invention includes a housing body having four sides surrounded by a lower plate, an upper plate facing the lower plate, and left and right side plates connecting the lower plate and the upper plate, thereby forming an insertion hole into which a strip-shaped insertion piece of a mating connector is inserted, and the opening at the front is used as a receiving opening of the insertion piece facing the insertion hole, the substrate is used as a lower plate of the box body, one plate surface of the substrate on which the wire harness guide part is formed is used as the upper surface of the lower plate forming the inner surface of the insertion hole, and the other plate surface of the substrate of the cover is surface-bonded for holding the wire harness is used as the lower surface of the lower plate, the front side protruding piece of the cover is formed as a front frame portion that covers the front surface of the box body when the cover is coupled to the box body, and the front frame portion is provided with an opening that opens the receiving opening to the front.

With the above configuration, the insertion piece of the mating connector can be inserted into the insertion hole of the housing through the receiving opening opened in the front surface of the housing. The electrical contact on the lower surface of the inserted insertion piece can be brought into sliding contact with a conductor exposure portion (electrical contact) of a harness guide portion disposed on the upper surface of a lower plate (substrate) of the housing. Further, the insertion piece of the counterpart connector can be inserted into the receiving opening of the box body through the opening of the front frame portion of the cover. Therefore, the front frame portion can be provided in a size covering the entire front end surface of the case, and the integral bonding property with the case can be further improved.

Further, since the front frame portion is shaped to be fitted to the mating connector, the cover is supplementarily supported by the mating connector. Therefore, the cover can be reliably prevented from falling off the case.

In the connector housing according to the present invention, a notch for accommodating the U-shaped bent portion of the conductor exposure portion is provided at a front edge portion of the harness guide portion.

With the above configuration, when the conductor exposed portion is bent at the front end edge of the substrate, the bending can be easily performed without lateral displacement at a stable position. Further, since the bent portion of the conductor exposure portion can be accommodated inside the notch, it is difficult to form a protrusion due to bending at the front end of the substrate (the lower plate of the case), and it is easy to bring the front frame portion of the cover into close contact with the front end surface of the case.

In the connector housing according to the present invention, the connector housing is provided with a through hole penetrating from one plate surface to the other plate surface of the board at a rear portion of the harness guide portion.

With the above configuration, the tip end of the conductor exposure portion can be arranged on the harness guide portion while the tip end of the conductor exposure portion is hooked on the through hole provided in the lower plate (substrate). In this state, for example, the middle portion of the conductor exposed portion may be bent in a U shape with the front end edge of the lower plate (substrate) as a bending fulcrum. Therefore, the bending operation can be performed in a state where the distal end of the conductor exposed portion is restrained in the through hole, and therefore, the bending operation can be performed particularly stably and easily. In addition, the position of the distal end of the conductor exposure portion in the case can be confirmed from the outside through the through-hole, regardless of whether the distal end of the conductor exposure portion is hooked on the through-hole provided in the lower plate (substrate). Therefore, the accuracy of the position of the conductor exposure portion or the bending position arranged on the wire harness guide portion can be improved.

In the connector housing according to the present invention, a window portion through which the through-hole can be seen from the outside is provided on the upper plate of the housing.

With the above configuration, the state of the conductor exposed portion being caught by the through-hole can be confirmed when viewed through the window portion, and the bending operation of the conductor exposed portion can be performed while confirming the state of the conductor exposed portion being caught.

In the connector housing of the present invention, the case is provided as a part of a housing main body, and the cover is integrally coupled to the housing main body via a bendable hinge.

With the above configuration, the connector housing can be manufactured by integrally molding a resin. Further, the hinge is bent, whereby the cover can be coupled to the housing body in a state of being aligned with respect to the housing body.

A connector according to the present invention is a connector in which a distal end of a wire harness is introduced into a connector housing, a U-shaped bent portion of a conductor exposed portion at the distal end of the wire harness is arranged at a distal end edge of a board, a portion of the conductor exposed portion on a distal end side with respect to the U-shaped bent portion is arranged on a first board surface of the board in a front-rear direction, a portion of the conductor exposed portion on a proximal end side with respect to the U-shaped bent portion is arranged on a second board surface of the board in the front-rear direction, a portion on the distal end side or a portion on the proximal end side of the conductor exposed portion is arranged in the wire harness guide portion provided on one of the first board surface and the second board surface, the proximal end side or the distal end side of the conductor exposed portion is configured as an electrical contact for making electrical conduction contact with an electrical contact of a mating connector, and the cover surface is joined to the other board surface of the first board surface and the second board surface of the board, the wire harness is sandwiched between the wire harness and the substrate, and in this state, the cover and the substrate are coupled by the coupling member, whereby the front and rear tabs formed on the cover are engaged with the front and rear ends of the substrate, respectively.

With the above configuration, the movement of the substrate in the front-rear direction can be restricted by the cover, and the integral bonding between the cover and the substrate can be improved. Further, even when external force in the front-rear direction acts via the harness or the mating connector, the substrate and the cover can be prevented from being misaligned or disengaged.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, the movement of the substrate in the front-rear direction can be restricted by the cover, and the integration of the cover and the substrate can be improved. Further, even when external force in the front-rear direction acts via the harness or the mating connector, the substrate and the cover can be prevented from being misaligned or disengaged.

The connector described here is useful as a two-wire connector to be connected to a power supply terminal (a mating connector) of a hub dynamo of a bicycle, and is also widely available to users as other general electrical connectors. In the first embodiment, an example is shown in which the connector housing constituting the connector includes one part (integrally molded product). In the second embodiment, an example is shown in which the connector housing constituting the connector includes two parts (separate molded articles).

< first embodiment >

A connector housing according to a first embodiment of the present invention and a connector configured using the same will be described with reference to fig. 1 to 12.

Fig. 2 is a diagram showing a state before use of the connector housing 1, where (a) is a front view seen from the front, and (b) is a rear view seen from the rear with the top and bottom turned over. Fig. 3 is an explanatory view of a method of assembling the connector 2 using the connector housing 1, where (a) is a perspective view showing a state in which the conductor exposed portion Wa of the leading end Wa1 of the wire harness W is to be inserted into the housing body 10 from the front, (b) is a perspective view showing a state in which the base end side of the wire harness W is bent and extended rearward, and (c) is a perspective view showing a state in which the cover 50 is coupled to the housing body 10 and the connector 2 is completed. Fig. 4 is a perspective view showing a state where the counterpart connector 200 is about to be fitted to the completed connector 2.

The connector housing 1 of the first embodiment shown in fig. 1 and 2 is a main component for constituting a two-wire connector to be connected to a power supply terminal (counterpart connector) of a hub dynamo. The connector housing 1 is integrally molded with resin, and includes a housing body 10, a cover 50, and a hinge 60 connecting the housing body 10 and the cover 50.

Before the following description, the directivity is defined in advance as follows.

Each direction described below is a direction in the state of the finally completed connector 2 (see fig. 3 c and 4). First, the direction in which the mating connector is received when the mating connector (the power supply terminal of the hub dynamo, etc.) is fitted is referred to as a front direction (front side) X1, the opposite direction is referred to as a rear direction (rear side) X2, and the front-rear direction is denoted by X. Accordingly, fig. 1(a) is a view seen from diagonally front, and fig. 1(b) is a view seen from diagonally rear. The left side of fig. 1a is referred to as left side (left side) Y1 of the connector housing 1 when viewed from the front, and the right side of fig. 1a is referred to as right side (left side) Y1 when viewed from the front, and the left-right direction is represented by Y. The direction in which the case body 10 and the lid 50 are coupled to each other is referred to as a vertical direction Z, the direction in which the case body 10 is located in the coupled state is referred to as an upper (upper) direction Z1, and the direction in which the lid 50 is located is referred to as a lower (lower) direction Z2.

The connector housing 1 is configured by being combined with the front end of the wire harness without using a terminal fitting.

As shown in fig. 3(c) and 4, in the finally completed connector 2, the wire harness W extends rearward from the connector 2. Therefore, when viewed from the harness W extending rearward from the connector 2, the front end of the harness W is introduced forward from the rear with respect to the connector 2. For example, even when the leading end of the wire harness W is introduced from the front to the rear in the middle of the assembly as shown in fig. 3(a), the shape of the final connector 2 is a shape in which the leading end of the wire harness W is introduced from the rear to the front as shown in fig. 3 (c).

As shown in fig. 1 and 2, the housing body 10 of the connector housing 1 has a rectangular case 11, and the case 11 has a dimension in the vertical direction smaller than a dimension in the horizontal direction when viewed from the front. The case 11 is configured by four sides surrounded by a lower plate 11a, an upper plate 11b facing the lower plate 11a, and a left side plate 11c and a right side plate 11d connecting the lower plate 11a and the upper plate 11 b. The inside of the housing 11 is configured as an insertion hole 12 into which a strip-shaped insertion piece 201 (see fig. 4) of the mating connector 200 is inserted. The front face of the insertion hole 12 is opened as a receiving opening 12a for receiving the insertion piece 201 of the counterpart connector 200. The insertion hole 12 of the case 11 is internally closed by a rear wall 13.

In the left side plate 11c and the right side plate 11d of the case 11, a plate-like rib 14 having a U-shape in front view is integrated so as to cover the outer peripheral surface of the upper half portion and the outer peripheral surface of the upper plate 11 b. An engagement claw 16 (coupling member) projecting leftward Y1 is provided on the outer side of the left end portion of the lower plate 11a of the housing 11. A lid 50 is coupled to the right end outside of the lower plate 11a of the case 11 via a hinge 60. Therefore, the cover 50 before assembly is disposed on the right side Y2 of the housing body 10.

Here, as shown in fig. 3(a), the wire harness W is one in which a wire harness core (wire) Wa is covered with an insulating coating Wb. The wire harness core Wa may include a plurality of bare wires or may include one bare wire (single wire). When the distal end of the wire harness W is introduced into the connector housing 1, the insulation coating Wb is stripped off within a predetermined length range from the distal end of the wire harness W, and the wire harness core Wa is exposed. Here, the exposed wire harness core wire Wa at the distal end is referred to as a conductor exposed portion Wa and is denoted by the same symbol as the conductor Wa.

As shown in fig. 1 and 2, the lower plate 11a of the housing 11 is configured as a substrate that supports a conductor exposure portion Wa bent in a U-shape at the front end of the wire harness W. The lower plate 11a as a substrate has portions functioning as a first plate surface, a front edge, and a second plate surface, respectively, which will be described below. That is, the lower plate 11a as the substrate has the leading edge KC of the U-shaped bent portion where the conductor exposed portion Wa is disposed. The lower plate 11a has a lower surface KB as a first plate surface, and a portion of the conductor exposed portion Wa closer to the base end side than the U-shaped bent portion is arranged along the front-rear direction. The lower plate 11a has an upper surface KA (inner bottom surface of the insertion hole 12) as a second plate surface, and a portion of the conductor exposed portion Wa on the front end side of the U-shaped bent portion is arranged along the front-rear direction on the upper surface KA.

Two wire harness holding projections 20 having a semicircular cross section are provided in parallel in the front-rear direction on the upper surface KA (corresponding to one plate surface) of the lower plate 11a of the housing body 10 with an interval in the left-right direction Y. On the upper surface of these wire harness holding convex portions 20, a wire harness guide groove (wire harness guide portion) 23 on which the distal end side of the conductor exposure portion Wa is placed is provided. By disposing the distal end side of the conductor exposure portion Wa (the distal end side of the U-shaped bent portion) in these harness guide grooves 23, the distal end side of the conductor exposure portion Wa can be used as an electrical contact.

A notch 24 having a V-shape or U-shape as viewed from above is provided at the front edge of the harness guide groove 23, and the notch 24 serves as a fulcrum for bending while guiding bending when bending the intermediate portion of the conductor exposed portion Wa into a U-shape. Further, a through-hole 21 penetrating from the upper surface KA to the lower surface KB of the lower plate 11a is provided at a position on the rear side X2 on the harness guide groove 23 of the harness holding convex portion 20. Further, the upper plate 11b of the case 11 is provided with a notch-shaped window 15 through which the periphery of the through-hole 21 can be viewed from above the case 11. Further, a conical surface-shaped guide wall 28 is provided on the rear wall 13 at the closed rear end of the housing 11, and the conical surface-shaped guide wall 28 guides the conductor exposed portion Wa placed on the harness guide groove 23 downward Z2 while holding the front end Wa1 when the front end Wa1 hits against the front end Wa 1.

Further, a harness support portion 25 having a harness support groove 26 is provided on the lower surface KB of the lower plate 11a, which is the lower surface of the housing body 10, corresponding to the harness holding convex portion 20 on the upper surface KA of the lower plate 11 a. The harness support portion 25 is provided only at a portion on the front end side of the lower plate 11a, and is provided at the rear side thereof with a harness guide groove 22 capable of accommodating the harness W of the portion with the cladding Wb. The inner peripheral surface of the harness guide groove 22 is larger in size than the inner peripheral surface of the harness support groove 26 on the front side thereof in order to accommodate the harness W in the portion with the cladding Wb. Therefore, there is a slight step difference in the boundary between the harness support groove 26 and the harness guide groove 22.

The rear through-hole 21 formed in the harness guide groove 23 on the upper surface KA of the lower plate 11a opens to the inner bottom of the harness guide groove 22. Specifically, the harness guide groove 23 is provided on the upper surface KA of the lower plate 11a, and the harness guide groove 22 is provided on the lower surface KB of the lower plate 11 a. The inner bottom surface of the harness guide groove 23 on the upper surface KA and the inner bottom surface of the harness guide groove 22 on the lower surface KB are formed at a height position overlapping each other, and the through-hole 21 is opened. Therefore, the inner surface of the conical guide wall 28 provided on the rear wall 13 is continuous with the inner surface of the harness guide groove 22 on the lower surface KB side.

The lower surface KB of the case body 10 is a plate surface of the face joint cover 50. The cover 50 has a main board 51, and the main board 51 includes a board surface face-bonded to the lower surface KB of the housing body 10. In fig. 1(b), a plate surface visible from above is a joint surface of the main plate 51. The wire harness W is sandwiched between the plate surface and the lower surface KB of the case body 10.

One side end portion of the main plate 51 is connected to a portion outside the right end portion of the lower plate 11a of the housing body 10 via a bendable hinge 60. The hinge 60 is bendable by 180 degrees as a whole and includes two

hinge portions

61, 62 bendable by 90 degrees. The two-

stage hinge portions

61 and 62 are formed as thin portions by forming V-grooves 61a and 61b along the front-rear direction on the surfaces of the bent sides of the fixed-thickness strip plates connecting the lower plate 11a of the case body 10 and the main plate 51 of the cover 50, respectively.

By bending the two

hinge portions

61 and 62 by 90 degrees, the cover 50 can be rotated by 180 degrees, and the main plate 51 of the cover 50 can be surface-joined to the lower surface KB of the case main body 10. At this time, the V grooves 61a and 61b are crushed, and both slopes of the ridge portion 63 including the common slope of the two V

grooves

61a and 62a are joined to the other slopes of the

V grooves

61a and 62 a. This allows the main board 51 to be surface-bonded to the lower surface KB of the case main body 10 while eliminating the positional deviation in the left-right direction Y.

An engagement claw 56 (coupling member) is provided on the main plate 51 of the cover 50 at the side edge portion on the side of the hinge 60, and the engagement claw 56 elastically engages with the engagement claw 16 on the side of the housing body 10 when the main plate 51 is coupled to the housing body 10. When the housing body 10 and the cover 50 are surface-joined with the wire harness W sandwiched therebetween, the engaging

claws

16 and 56 are engaged with each other, whereby the housing body 10 and the cover 50 are integrally joined. In this case, since one end side is coupled by the hinge 60, the engaging

claws

16 and 56 may be provided only on the other end side. Further, the engagement between the housing body 10 and the cover 50 can be released by releasing the engagement between the engagement claws 16 on the housing body 10 side and the engagement claws 56 on the cover 50 side.

A front frame 52 is provided as a front projecting piece at the front end of the cover 50. The front frame portion 52 is provided so as to cover the front surface of the case body 10 when the cover 50 is coupled to the case body 10. By being disposed so as to cover the front surface of the housing main body 10 as described above, the front frame portion 52 can be restricted so as not to move the housing main body 10 forward in a state of being engaged with the front end of the housing main body 10. The front frame portion 52 is provided with an opening 52a that opens the receiving opening 12a of the insertion hole 12 of the housing body 10 toward the front.

In addition, a rear side projecting piece 53 is provided at the rear end of the cover 50. The rear-side projecting piece 53 is engaged with the rear end of the housing body 10 when the cover 50 is coupled to the housing body 10. Thereby, the housing body 10 is regulated so as not to move rearward.

Next, an assembling procedure of the connector using the connector housing 1 having the above-described configuration will be described.

Fig. 6 is a perspective view for explaining a key for bending the intermediate portion of the conductor exposure portion Wa in a U shape toward the lower surface KB side of the housing main body 10.

Fig. 7 is a side sectional view for explaining a method of assembling the conductor exposed portion Wa at the distal end of the wire harness W into the housing body 10, and shows a state in which the conductor exposed portion Wa at the distal end of the wire harness W is inserted into the insertion hole 12 of the housing body 10 from the front. Fig. 8 is a side sectional view showing a state in which the hook-shaped portion of the distal end Wa1 of the conductor exposed portion Wa is caught in the through-hole 21 after the state of fig. 7. Fig. 9 is a side sectional view showing a state in which the intermediate portion of the conductor exposure portion Wa is bent into a U shape toward the lower surface KB side of the housing main body 10 after the state of fig. 8, and the base end side of the wire harness W is extended rearward. Fig. 7 and 8 correspond to detailed views for explaining the step of fig. 3 (a). Fig. 9 corresponds to a detailed diagram for explaining the step of fig. 3 (b).

Fig. 10 is a side sectional view showing the following state: by coupling the cover 50 to the housing body 10 in the state of fig. 9, the base end side of the wire harness W is sandwiched between the housing body 10 and the cover 50, the connector 2 in which the tip end side of the conductor exposure portion Wa is an electrical contact inside the insertion hole 12 is completed, and the insertion piece 201 of the counterpart connector 200 is to be inserted toward the connector 2. Fig. 10 is a cross-sectional view corresponding to the state of fig. 4.

When assembling the connector 2, first, as shown in fig. 3(a), 5, and 7, the distal end Wa1 of the conductor exposed portion Wa of the wire harness W is inserted into the insertion hole 12 of the housing body 10 from the front. At this time, the distal end Wa1 of the conductor exposure portion Wa is bent downward into a hook shape, and this portion is caught by the through hole 21 of the lower plate 11a of the housing body 10 (the operation of arrow S1 in fig. 5 and 7). As a result, as shown in fig. 8, the distal end side of the conductor exposure portion Wa can be disposed in the harness guide groove 23 with reference to the portion hooked on the through-hole 21.

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

At this time, the distal end Wa1 of the conductor exposed portion Wa is bent in a state of being constrained in the through-hole 21, and thus the bending can be stably and easily performed. The bending operation of the conductor exposed portion Wa can be performed while confirming the state of the distal end Wa1 of the conductor exposed portion Wa being caught by the through-hole 21 through the window portion 15. In the bending, the conductor exposed portion Wa can be bent without being laterally displaced at a stable position because the bending is performed using the notch 24.

As shown in fig. 6, the proximal end side of the conductor exposure portion Wa guided to the lower surface KB side of the lower plate 11a after bending is housed in the harness support groove 26 of the harness support portion 25 provided on the lower surface KB side of the lower plate 11 a. The portion of the wire harness W with the cladding Wb extending toward the base end side of the wire harness W beyond the conductor exposed portion Wa is accommodated in the wire harness guide groove 22 in a state of extending toward the rear of the connector housing 1.

In this state, as shown in fig. 3 c and 10, the hinge 60 (see fig. 1 and 2) is bent to bring the main plate 51 of the cover 50 into surface contact with the lower surface KB of the housing main body 10 (operation of arrow F in fig. 10). Then, the engagement claws 56 of the cover 50 are engaged with the engagement claws 16 of the housing body 10. By doing so, the wire harness W can be sandwiched between the lower surface KB of the lower plate 11a of the housing body 10 and the main plate 51 of the cover 50.

By passing through the above sequence, the connector 2 shown in fig. 3(c) and 10 is completed.

In the connector 2, the proximal end side of the conductor exposure portion Wa at the distal end of the wire harness W, which is introduced from the rear to the front, is disposed on the lower surface KB (first plate surface) of the lower plate 11a of the housing body 10. The bent portion in the U shape of the conductor exposed portion Wa is disposed in the shape of the front end edge KC of the lower plate 11 a. The distal end side of the conductor exposure portion Wa is disposed on the upper surface KA (second plate surface) side of the lower plate 11 a. The distal end side of the conductor exposure section Wa is disposed in a harness guide groove 23 formed in the upper surface of the lower plate 11a, and thereby is configured as an electrical contact that makes conductive contact with an electrical contact 202 on the lower surface of the insertion piece 201 of the mating connector 200. In addition, the wire harness W is sandwiched between the housing body 10 and the cover 50.

When the cover 50 is coupled to the housing body 10 as described above, the front frame portion 52 as the front side projection of the cover 50 is engaged with the front end of the housing body 10, and the rear side projection 53 of the cover 50 is engaged with the rear end of the housing body 10. Therefore, the movement of the housing body 10 in the front-rear direction can be restricted by the cover 50, and the integral bonding property of the cover 50 and the housing body 10 can be improved.

Further, since the bent portion of the conductor exposure portion Wa can be accommodated inside the notch 24, the protrusion due to the bending cannot be formed at the front end of the lower plate 11a of the housing body 10. Therefore, the front frame portion 52 of the cover 50 can be disposed in close contact with the front end surface of the case 11 of the housing body 10.

In the connector 2 having the above-described configuration, as shown in fig. 4 and 10, the insertion piece 201 of the mating connector 200 can be inserted into the insertion hole 12 of the housing body 10 through the opening 52a and the receiving opening 12a of the front frame 52 of the cover 50 (operation of arrow M in fig. 10). Further, the electrical contact 202 on the lower surface of the inserted insertion piece 201 can be brought into sliding contact with the conductor exposed portion Wa (electrical contact) supported on the harness guide groove 23 of the lower plate 11a of the insertion hole 12. When the mating connector 200 is inserted, the distal end Wa1 of the conductor exposed portion Wa receives a frictional force in a direction of being pushed into the back side of the insertion hole 12. Therefore, the wire harness W becomes difficult to fall off from the connector housing 1.

Further, since the mating connector 200 is fitted to the housing main body 10 through the opening 52a of the front frame 52 covering the entire front end surface of the housing main body 10, the coupling property of the housing main body 10 to the cover 50 and the mating connector 200 is also increased. Therefore, even when an external force in the front-rear direction has been applied to the connector 2 via the wire harness W or the mating connector 200, the coupling between the housing body 10 and the cover 50 can be prevented from being deviated or from being disengaged.

Further, since the front frame portion 52 is shaped to fit the mating connector 200, the cover 50 is supplementarily supported by the mating connector 200. Therefore, the cover 50 can be reliably prevented from coming off the housing body 10.

In the above description, an example has been described in which the distal end Wa1 of the conductor exposed portion Wa is inserted into the insertion hole 12 of the housing body 10, and the distal end Wa1 of the conductor exposed portion Wa is bent into a hook shape and then caught in the through-hole 21. However, this may not be the case.

Fig. 11 is a view for explaining another method of assembling the conductor exposed portion Wa at the front end of the wire harness W into the housing body 10, and is a side sectional view showing a state in which the conductor exposed portion Wa at the front end of the wire harness W is to be inserted into the insertion hole 12 of the housing body 10 from the front. Fig. 12 is a side sectional view showing the following state: after the state of fig. 11, the base end side of the wire harness W is sandwiched between the housing body 10 and the cover 50 by bending the intermediate portion of the conductor exposure portion Wa into a U shape toward the lower surface KB side of the housing body 10 and extending the base end side of the wire harness W rearward, and the connector 2 in which the tip end side of the conductor exposure portion Wa is an electrical contact 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 by coupling the cover 50 to the housing body 10.

As shown in fig. 11, in this example, the distal end Wa1 of the conductor exposed portion Wa is inserted into the insertion hole 12 in a state where the conductor exposed portion Wa of the wire harness W is placed in the harness guide groove 23 of the housing body 10. The tip Wa1 of the conductor exposed portion Wa in an unbent state is caused to strike against the conical guide wall 28 of the rear wall 13 inside the insertion hole 12. Then, the distal end Wa1 of the conductor exposed portion Wa is held inside the conical guide wall 28, and the distal end Wa1 of the conductor exposed portion Wa can be guided downward.

In this 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. At the time of the bending, since the portion inserted into the conical guide wall 28 is fixed to the conical guide wall 28, the tip Wa1 of the conductor exposed portion Wa does not float due to a reaction caused by the bending. Therefore, the bending can be stably performed. The position of the distal end Wa1 of the conductor exposed portion Wa (the portion inserted into the conical surface-shaped guide wall 28) can be confirmed from the upper side or the lower side of the housing body 10 through the window 15 or the through-hole 21. Therefore, failure of bending caused by reaction at the time of bending can be prevented, and the accuracy of the position of the conductor exposed portion Wa or the position of bending that has been arranged in the harness guide groove 23 can be improved.

After bending the cover into a U-shape, the harness W is arranged in the same manner as in the previous example, and the hinge 60 (see fig. 1 and 2) is bent so that the main plate 51 of the cover 50 is surface-joined to the lower surface KB of the case main body 10. Then, the engagement claws 56 of the cover 50 are engaged with the engagement claws 16 of the housing main body 10, whereby the wire harness W is sandwiched between the housing main body 10 and the cover 50 as shown in fig. 12. Thereby, the connector 2 can be completed.

In the above description, the case where the conductor exposed portion Wa in an unfolded state is inserted into the case body 10, and the middle portion of the conductor exposed portion Wa is bent in a U shape by the front end edge KC of the lower plate 11a is described.

However, it is not necessary to bend the conductor exposed portion Wa into a U shape after it is introduced into the housing body 10. That is, the conductor exposure portion Wa may be bent into a U shape in advance, and the conductor exposure portion Wa in the U-shaped bent state may be assembled to the case main body 10. In this case, the U-shaped bent portion is disposed at the front end edge KC of the housing body 10, and the wire harness guide groove 23 is disposed on the upper surface KA side of the lower plate 11a by inserting the conductor exposed portion Wa closer to the front end side than the U-shaped bent portion into the insertion hole 12. The harness support groove 26 of the lower surface KB of the lower plate 11a of the housing body 10 is disposed on the proximal side of the U-shaped bent portion of the conductor exposed portion Wa, and the harness W with the clad Wb is disposed in the harness guide groove 22. The subsequent sequence is the same as the description.

In the above description, the case where the distal end Wa1 side of the conductor exposed portion Wa of the wire harness W is disposed on the upper surface KA of the lower plate 11a of the housing body 10, and the portion of the conductor exposed portion Wa closer to the proximal end side than the U-shaped bent portion is disposed on the lower surface KB of the lower plate 11a is described.

However, as shown in fig. 13, the housing body 10 can also be configured as follows: a portion of the conductor exposure portion Wa of the wire harness W closer to the base end side than the U-shaped bent portion is disposed on the upper surface KA of the lower plate 11a, and a tip Wa1 side of the conductor exposure portion Wa of the wire harness W is disposed on the lower surface KB of the lower plate 11 a.

< second embodiment >

Next, a connector housing according to a second embodiment of the present invention and a connector configured using the same will be described with reference to fig. 14 to 17.

Here, the first embodiment is different from the second embodiment in the following point: the connector housing 1 of the first embodiment is configured as one component in which the housing body 10 and the cover 50 are connected by the hinge 60, but the connector housing of the second embodiment is configured as two components in which the housing body and the cover are separate bodies.

Other large differences are the following.

That is, in the first embodiment, the base end side of the conductor exposure portion Wa is disposed on the lower surface KB side of the lower plate 11a of the housing body 10, and the tip end side of the conductor exposure portion Wa is disposed on the upper surface KA side of the lower plate 11a of the housing body 10. The distal end side of the conductor exposed portion Wa serves as an electrical contact. In contrast, in the second embodiment, the base end side of the conductor exposure portion Wa is disposed on the upper surface KA side of the lower plate 11a of the housing body 10, and the tip end side of the conductor exposure portion Wa is disposed on the lower surface KB side of the lower plate 11a of the housing body 10. The distal end side of the conductor exposed portion Wa serves as an electrical contact.

Due to the difference, the introduction portion of the front end of the wire harness W into the connector housing (or the extraction portion of the wire harness W from the connector housing) differs between the first embodiment and the second embodiment. That is, in the former first embodiment, the introduction portion is formed between the lower surface KB of the casing body 10 and the cover 50. In contrast, in the second embodiment, the introduction portion is an insertion hole 121 (described later) of the rear wall 113 of the housing body 110.

Fig. 14 is a perspective view of the connector housing 101 according to the second embodiment of the present invention before use, as viewed from obliquely upper front, and fig. 15 is a perspective view as viewed from obliquely lower front.

The connector housing 101 of the second embodiment shown in fig. 14 and 15 is also a main component for constituting a two-wire connector connected to a power supply terminal (counterpart connector) of the hub dynamo. The connector housing 101 of this embodiment includes a housing body 110 and a cover 150 which are respectively molded with resin. The directionality of the member is the same as that of the first embodiment, and therefore, the description thereof is omitted.

As shown in fig. 14 and 15, the case body 110 has a rectangular case 111, and the case 111 has a smaller vertical dimension than a horizontal dimension when viewed from the front. The case 111 is configured by surrounding four sides with a lower plate 111a, an upper plate 111b facing the lower plate 111a, and a left side plate 111c and a right side plate 111d connecting the lower plate 111a and the upper plate 111 b. The inside of the housing 111 is configured as an insertion hole 112 into which a strip-shaped insertion piece 201 (see fig. 4) of the mating connector 200 is inserted. The front face of the insertion hole 112 is opened as a receiving opening 112a that receives the insertion piece 201 of the counterpart connector 200. The insertion hole 112 of the case 111 is internally closed by a rear wall 113.

The U-shaped plate-like rib 114 is integrated so as to cover the outer peripheral surfaces of the upper half portions of the left and

right side plates

111c, 111d of the case 111 and the outer peripheral surface of the upper plate 111b in front view. Engaging claws 116 (coupling members) are provided on the outer sides of the left and right end portions of the lower plate 111a of the case 111.

The lower plate 111a of the case 111 is configured as a substrate on which the conductor exposure portion Wa at the distal end of the wire harness W is mounted. The lower plate 111a as a substrate has portions functioning as a first plate surface, a leading edge, and a second plate surface, which will be described later. That is, the lower plate 111a as the substrate has the leading edge KC of the U-shaped bent portion where the conductor exposed portion Wa is disposed. The lower plate 111a has an upper surface KA (inner bottom surface of the insertion hole 12) as a first plate surface, and a portion of the conductor exposed portion Wa closer to the base end side than the U-shaped bent portion is arranged along the front-rear direction on the upper surface KA. The lower plate 111a has a lower surface KB as a second plate surface, and a portion of the conductor exposed portion Wa on the front end side of the U-shaped bent portion is arranged along the front-rear direction.

The two harness holding projections 120 are provided in parallel in the front-rear direction on the upper surface KA (corresponding to one plate surface) of the lower plate 111a of the housing body 110 with an interval in the left-right direction Y. On the upper surface of these wire harness holding convex portions 120, a wire harness guide groove (wire harness guide portion) 123 on which the distal end side of the conductor exposure portion Wa is placed is provided. By disposing the base end side of the conductor exposure portion Wa (closer to the base end side than the U-shaped bent portion) in these harness guide grooves 123, the base end side of the conductor exposure portion Wa can be used as an electrical contact.

A notch 124 having a V-shape or U-shape as viewed from above is provided at the front edge of the harness guide groove 123, and the notch 124 guides bending and serves as a fulcrum of bending when bending the intermediate portion of the conductor exposed portion Wa into a U-shape. Two insertion holes 121 into which the conductor exposure portions Wa are inserted from behind are provided in the rear wall 113 of the case 111 that closes the rear end. These insertion holes 121 are positioned on the extensions of the harness guide grooves 123 so that the conductor exposed portions Wa introduced from the insertion holes 121 can be directly placed on the harness guide grooves 123.

In addition, two harness support grooves 126 are provided on the lower surface KB of the lower plate 111a, which is the lower surface of the housing body 110, corresponding to the two harness guide grooves 123 on the upper surface KA of the lower plate 111 a. The wire harness support groove 126 extends rearward from the front end edge of the lower plate 111a, and the front end becomes the end point.

The lower surface KB of the housing body 110 is a plate surface of the surface-engaging cover 150. The cover 150 has a main plate 151, and the main plate 151 includes a plate surface facing the lower surface KB of the case body 110. In fig. 14, a plate surface that can be seen from above is a joint surface of the main plate 151. The distal end side of the conductor exposure section Wa is sandwiched between the plate surface and the lower surface KB of the case main body 110. Two harness support grooves 154 are provided on the joint surface of the cover 150 so as to correspond to the harness support grooves 126 on the lower surface of the housing body 110. These harness support grooves 154 also extend rearward from the front end edge of the main plate 151, and the front end becomes a terminal point.

Engaging claws 156 (coupling members) are provided at both ends in the left-right direction of the main plate 151, and the engaging claws 156 elastically engage with the engaging claws 116 on the case main body 110 side when the main plate 151 and the case main body 110 are coupled. When the housing body 110 and the cover 150 are surface-joined with the wire harness W sandwiched therebetween, the engaging

claws

116, 156 are engaged with each other, and the housing body 110 and the cover 50 are integrally joined. Further, the engagement between the housing body 110 and the cover 150 can be released by releasing the engagement between the engagement claws 116 on the housing body 110 side and the engagement claws 156 on the cover 150 side.

A front frame portion 152 is provided as a front side projecting piece at the front end of the cover 150. The front frame portion 152 is provided so as to cover the front surface of the case body 110 when the cover 150 is coupled to the case body 110. By being disposed so as to cover the front surface of the housing main body 110 as described above, the front frame portion 152 can be restricted so as not to move the housing main body 110 forward in a state of being engaged with the front end of the housing main body 110. The front frame portion 152 is provided with an opening 152a that opens the receiving opening 112a of the insertion hole 112 of the housing body 110 toward the front.

In addition, a rear tab 153 is provided at the rear end of the cover 150. The rear-side tabs 153 snap into the rear end of the housing body 110 when the cover 150 has been coupled to the housing body 110. Thereby, the housing body 110 is restricted so as not to move rearward.

Next, an assembling procedure of the connector using the connector housing 101 having the above-described configuration will be described.

Fig. 16 is a perspective view showing a state in which the conductor exposure portion Wa at the front end of the wire harness W is inserted from behind 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 exposure portion Wa inserted into the housing body 110 is bent into a U shape toward the lower surface side of the housing body 110 after the state of fig. 16.

When assembling the connector using the connector housing 101, first, as shown in fig. 16, the front end Wa1 of the conductor exposed portion Wa of the wire harness W is inserted into the insertion hole 112 from the insertion hole 121 provided in the rear wall 113 of the connector housing 101 (action of arrow S1). As shown in fig. 17, the base end side of the inserted conductor exposure section Wa is placed on the harness guide groove 123. Then, while the intermediate portion of the conductor exposure portion Wa exposed from the harness guide groove 123 is accommodated in the notch 124, the distal end side of the conductor exposure portion Wa is bent downward and is bent into a U shape directly along the lower surface KB of the case main body 110 (operation of arrow S2). At this time, the proximal end side of the conductor exposure section Wa is held and fixed to the insertion hole 121, and thus can be stably and easily bent. Then, the distal end side of the conductor exposure portion Wa is disposed in the wire harness support groove 126 of the lower surface KB of the housing body 110.

In this state, the main plate 151 of the cover 150 is surface-bonded to the lower surface KB of the housing body 10 (the 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 front end side of the conductor exposure portion Wa of the wire harness W can be sandwiched between the lower surface KB of the lower plate 111a of the housing body 110 and the main plate 151 of the cover 150.

By passing through the above sequence, the connector can be completed. In this connector, the base end side of the conductor exposure portion Wa of the distal end of the wire harness W, which is introduced from the rear to the front, is disposed on the upper surface KA (first plate surface) of the lower plate 111a of the housing body 110. The U-shaped bent portion of the conductor exposed portion Wa is disposed at the front edge KC of the lower plate 111 a. The distal end side of the conductor exposure portion Wa is disposed on the lower surface KB (second plate surface) of the lower plate 111 a. The base end side of the conductor exposure section Wa is disposed in a harness guide groove 123 formed in the upper surface of the lower plate 111a, and thereby is configured as an electrical contact that makes conductive contact with an electrical contact 202 on the lower surface of the insertion piece 201 of the mating connector 200. Further, the distal end side of the conductor exposure section Wa is sandwiched between the housing body 110 and the cover 150.

When the cover 150 is coupled to the housing body 110 as described above, the front frame portion 152 as the front side projection of the cover 150 is engaged with the front end of the housing body 110, and the rear side projection 153 of the cover 150 is engaged with the rear end of the housing body 110. Therefore, the movement of the housing body 110 in the front-rear direction is restricted by the cover 150, and the integral coupling of the cover 150 and the housing body 110 can be improved.

Further, since the bent portion of the conductor exposure portion Wa can be accommodated inside the notch 124, the protrusion due to the bending cannot be formed at the tip of the lower plate 111a of the housing body 110. Therefore, the front frame portion 152 of the cover 150 can be disposed in close contact with the front end surface of the case 111 of the housing body 110.

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

Further, since the mating connector 200 is fitted to the housing main body 110 through the opening 152a of the front frame portion 152 that covers the entire front end surface of the housing main body 110, the coupling property of the housing main body 110 to the cover 150 and the mating connector 200 is also increased. Therefore, even when an external force in the front-rear direction has been applied to the connector via the wire harness W or the mating connector 200, the coupling between the housing body 110 and the cover 150 can be prevented from being deviated or from being disengaged.

When the conductor exposure portion Wa is bent in a U shape, the conductor exposure portion Wa may be pushed and bent by the cover 150. In this case, the cover 150 is directly coupled to the housing main body 110, and thereby the distal end side of the conductor exposure section Wa can be sandwiched between the housing main body 110 and the cover 150.

The present invention is not limited to the above-described embodiments, and various modifications may be made to the above-described embodiments without departing from the spirit of the present invention.

For example, in the above-described embodiment, the case where the number of the wire harnesses W introduced into the connector housing 1 and the connector housing 101 is two is shown, but the number of the introduced wire harnesses may be one, or may be three or more. The number of portions supporting the conductor exposure portions may be changed in accordance with the number.

a substrate that supports a conductor exposure portion bent in a U shape of a front end of a wire harness when a direction in which a mating connector is fitted is set to a front side, and that has a front end edge of a U-shaped bent portion on which the conductor exposure portion is disposed, a first plate surface on which a portion of the conductor exposure portion closer to a base end side than the U-shaped bent portion is disposed along a front-rear direction, and a second plate surface on which a portion of the conductor exposure portion closer to a front end side than the U-shaped bent portion is disposed along the front-rear direction;

a harness guide portion provided on one of the first plate surface and the second plate surface, the harness guide portion supporting a portion of the one plate surface, which is disposed on a distal end side or a proximal end side of the conductor exposure portion, as an electrical contact for making conductive contact with an electrical contact of a mating connector;

a cover that is surface-bonded to the other of the first plate surface and the second plate surface, and that sandwiches the wire harness with the substrate;

a coupling member that is capable of coupling and decoupling the substrate and the cover in a state in which the wire harness is held; and

and front and rear protruding pieces provided at front and rear ends of the cover, and engaged with front and rear ends of the substrate when the cover is coupled to the substrate, respectively, to position-regulate the substrate in a front-rear direction.

2. The connector housing of claim 1,

the connector includes a box body, wherein four sides of the box body are surrounded by a lower plate, an upper plate opposite to the lower plate, and a left side plate and a right side plate which connect the lower plate and the upper plate, thereby forming an insertion hole for inserting a strip plate-shaped insertion piece of a counterpart connector, and an opening at the front surface is used as a receiving port of the insertion piece facing the insertion hole,

the board is provided as a lower plate of the box body, one plate surface of the board on which the wire harness guide is formed is an upper surface of the lower plate constituting an inner surface of the insertion hole, and the other plate surface of the board on which the cover is surface-bonded for sandwiching the wire harness is a lower surface of the lower plate,

the front side protruding piece of the cover is formed as a front frame portion that covers the front surface of the box body when the cover is coupled to the box body, and the front frame portion is provided with an opening that opens the receiving opening to the front.

3. The connector housing of claim 2,

the front edge of the harness guide is provided with a notch for accommodating the U-shaped bent portion of the conductor exposure portion.

4. Connector housing according to claim 2 or 3,

the rear portion of the wire harness guide is provided with a through hole penetrating from one plate surface of the substrate to the other plate surface.

5. The connector housing according to claim 4,

the upper plate of the case is provided with a window portion through which the through hole can be recognized from the outside.
