Electrical connector assembly

Technical field

TECHNICAL FIELD [0001] The present invention relates to an electrical connector assembly that electrically connects a printed wiring board and an electric wire, and more particularly to a type of electrical connector assembly in which a contact is attached to a housing using a lance.

Background art

[0002] In addition to press-fitting and molding, a contact is mounted on the connector housing by forming a lance (protrusion) on one of the contact and housing, and a step formed on the other of the contact and housing. Some are engaged (see, for example, Patent Document 1). For example, when a lance is formed on the contact side, the contact is inserted into a groove or slit formed in the housing, and when the lance gets over the step formed on the housing, the lance and the step are engaged. As a result, the contact is held without falling off the housing.

In such a structure, in order to securely engage the lance and the stepped portion, as shown in FIG. 7, the length from the tip of the lance 1 to the tip 2a of the contact 2 is longer than the length L1. The length L2 from the step 4 of the housing 3 to the tip 5a of the groove or slit 5 is increased, and the contact is more than the position where the lance 1 and the step 4 engage when the contact 2 is inserted into the housing 3. It is necessary to form a clearance that allows 2 to move further in the insertion direction. This is to cope with errors in the contact 2 and housing 3 dimensions that are within the allowable range.

[0004] Patent Document 1: Japanese Patent Laid-Open No. 2003-243079

Disclosure of the invention

Problems to be solved by the invention

Due to the presence of the clearance as described above, the contact 2 has a backlash in the housing 3 along the insertion direction of the contact 2. There may be problems when connecting such GATAKA connectors.

For example, when play occurs and contact 2 is displaced from the correct position, May interfere with mating contacts.

In this way, if the connector is forcibly inserted even if the contacts interfere with each other, the contact may be deformed or damaged, and even if the deformation does not hinder the fitting. The electrical connection state may become unstable.

[0006] In order to facilitate the fitting of the male housing and the female housing, the edge of the male housing, the leading edge of the udging, and the peripheral edge of the recess formed in the female housing are chamfered. A taper shape is often used to guide both housings to the correct positions. Even if the housings are positioned in this way, if the contact is in a state where it moves relative to the housing due to backlash, the interference between the contacts and the! / I ca n’t.

[0007] When such looseness becomes a problem, it is preferable to fix the contact to the housing by press-fitting or molding with resin or the like.

However, in this case, it takes time to press-fit and mold after setting the contacts in the housing, and further, jigs and devices for press-fitting and molding are required, leading to an increase in manufacturing cost. Sometimes.

[0008] The present invention has been made based on such a technical problem, and it is possible to avoid contact deformation and to securely connect the contacts without particularly trouble and cost. An object is to provide an assembly. Means for solving the problem

[0009] An electrical connector assembly of the present invention made for such an object is an electrical connector assembly for electrically connecting a printed wiring board and an electric wire, and is a first fixed to the printed wiring board. A housing, a second housing that fits into the first housing, a first contact held in the first housing and electrically connected to the printed wiring board, and a second housing in the second housing And a second contact connected to the first contact and the electric wire. The second contact is held in a state in which backlash in a direction perpendicular to the fitting direction of the first housing can occur. In order to electrically connect the second contact and the first contact and to fit the second housing and the first housing, the second housing and the second contact are connected to the first housing and the first contact. When approaching one contact In addition, the guide force S that corrects the position of the second contact with respect to the first contact in the direction in which the play can occur, and the portion that is responsible for the electrical contact of the first contact and the second contact in the second contact It is characterized by being formed at a position different from the above. With such a configuration, even if the second contact is misaligned within the range of play, the position of the second contact with respect to the first contact in the direction in which play can occur is corrected by the guide portion. can do. As a result, when the first contact and the second contact are electrically connected, the first contact and the second contact can be prevented from colliding and deforming.

Here, the second contact is inserted into the second housing in a direction perpendicular to the fitting direction of the second housing and the first housing, and the second contact and the second contact are inserted. By engaging the lance force s formed on one side of the housing, the second contact and the step formed on the other side of the second housing, the second housing is held. In such a second contact holding structure, when a clearance is secured between the second contact and the second housing in order to ensure engagement between the lance and the stepped portion, the second contact is The first housing and the first housing are held in the second housing in a state in which backlash in a direction perpendicular to the fitting direction of the first housing can occur.

[0011] Now, it is preferable that the position of the second contact with respect to the first contact is corrected by sliding the guide portion along a sliding surface formed in the first housing. It is possible to correct the position of the second contact by placing the guide part against the first contact S, which may cause deformation of the first contact when the guide part hits the first contact. By sliding the guide portion against the sliding surface of the first housing instead of the first contact, deformation of the first contact is avoided.

[0012] When the second housing and the second contact are brought close to the first housing and the first contact, the portion in charge of electrical contact in the second contact comes into contact with the first contact. In advance, it is preferable that the guide portion touches the sliding surface. As a result, when the portion of the second contact responsible for electrical contact comes into contact with the first contact, the position of the second contact has already been corrected by the guide portion, and the second contact is moved to the first contact. Smooth electrical connection to other contacts That's the power S.

[0013] The guide portion may have any shape, but preferably has a plate shape. In this case, it is preferable that the end surface of the guide portion abuts against the sliding surface. When the guide part hits the sliding surface at the end face, the reaction force input to the guide part from the sliding surface side becomes a force in the in-plane direction of the plate-like guide part. As a result, the guide portion can exhibit high rigidity against the reaction force input from the sliding surface side, so that the durability of the second contact, which is difficult to deform, can be improved. it can.

Here, the first contact and the second contact may be electrically connected by clamping the second contact by sandwiching the second contact from both sides. In that case, the present invention is effective when the clamping force of the second contact in the first contact matches the direction in which the play of the second contact can occur. In other words, if a shift occurs in the position of the second contact due to backlash, the second contact will shift in the clamping direction of the first contact, and the first contact and the second contact will be shifted. Cause deformation due to interference. If the present invention is applied in such a case, the displacement of the second contact in the direction in which the play can occur, that is, the clamping direction of the first contact can be corrected by the guide portion, and the first contact can be corrected. Therefore, deformation due to the interference of the second contact can be avoided.

[0015] The electric wire connected to the second contact may extend in a direction perpendicular to the fitting direction of the second housing and the first housing. In the case of such a connection configuration, when the second contact is held by the second housing using the lance, the second contact is connected to the second housing, the second housing and the first housing. It is held in a state in which backlash in the direction perpendicular to the fitting direction can occur.

Here, the second contact includes a barrel portion that holds the end of the electric wire, a holding portion that is held by the second housing, and a plate portion that extends from the holding portion toward the fitting direction. A contact portion that is formed on both side ends of the plate portion and that makes electrical contact with the first contact, and the guide portion is continuous with the plate portion and is more than the contact portions on both side ends of the plate portion. It is preferable to project from the fitting direction side.

[0017] The electrical connector assembly of the present invention is an electrical connector for electrically connecting a printed wiring board and an electric wire. A connector assembly, a first housing fixed to the printed wiring board, a second housing fitted to the first housing, and electrically connected to the printed wiring board held by the first housing And a second contact held by the second housing and connected to the first contact and the wire, the second contact being a barrel that holds the end of the wire , A holding portion held by the second housing, a plate portion extending from the holding portion toward the first housing, and formed on both side ends of the plate portion, and is in electrical contact with the first contact A contact portion and a guide formed continuously to the plate portion so as to protrude from the contact portions on both side ends of the plate portion toward the fitting direction of the second housing with respect to the first housing. And de unit, Ru can be made with a. The second housing and the second contact are connected to the first housing in order to electrically connect the second contact and the first contact and to fit the second housing and the housing to the first housing. When the guide portion is brought close to the first contact, the guide portion slides on the sliding surface formed on the first housing, thereby correcting the position of the second contact with respect to the first contact. Features.

According to such a configuration, even when the second contact is misaligned, the position of the second contact can be corrected by the guide portion. As a result, when the first contact and the second contact are electrically connected, the first contact and the second contact can be prevented from colliding and deforming.

At this time, since the guide portion is provided so as to protrude in the fitting direction side from the contact portion, the second housing and the second contact are brought closer to the first housing and the first contact. When the contact is made, the guide portion hits the sliding surface before the portion that makes electrical contact with the second contact contacts the first contact, and the position of the second contact with respect to the first contact is corrected. Is done. Therefore, when the portion in charge of electrical contact in the second contact contacts the first contact, the position of the second contact is corrected by the guide section! / A single contact can be electrically connected smoothly.

Here, the guide portions respectively formed continuously from the contact portions on both side ends of the plate portion can be formed in steps. Guides are formed in steps on both sides of the plate. As a result, the guide portion sequentially contacts one side of the sliding surface, so that the position of the second contact can be corrected smoothly. The invention's effect

[0019] According to the present invention, even if the second contact is held in a state where play can occur with respect to the second housing, the first contact in the direction where play can occur is caused by the guide portion. The position of the second contact with respect to the contact can be corrected. As a result, when the first contact and the second contact are electrically connected, the first contact and the second contact are prevented from colliding and deforming, and the first contact is prevented. And the second contact can be electrically connected smoothly.

As a result, the second contact can be structured to be held in the second housing by using a lance that is not press-fitted or molded with resin or the like, and there is no need for extra labor, jigs, and equipment. Since it can be easily and inexpensively attached to the second housing, its manufacture can be performed at low cost.

FIG. 5 is a view showing a process of fitting the plug connector to the receptacle connector, and is a sectional view showing a state in which the follower plate is corrected in accordance with the guide surface formed on the receptacle housing. It is. FIGS. 6A and 6B are diagrams showing a process of fitting the plug connector to the receptacle connector, where FIG. 6A is a state following FIG. 5 and FIG. As shown in FIG. 1, the connector (electrical connector assembly) 10 includes a receptacle connector 20 fixed to the printed wiring board 11 side and a plug connector 30 that can be coupled to the receptacle connector 20. Here, the following description will be made with the printed wiring board 11 side of the receptacle connector 20 as the lower side and the plug connector 30 side as the upper side.

The receptacle connector 20 includes a resin-made receptacle housing (first housing) 21 and a contact (first contact) 22 formed from a conductive material such as a copper-based material.

As shown in FIG. 2, the receptacle housing 21 is fixed to the printed wiring board 11 by pegs 21a provided on the outer peripheral surface thereof. A recess 23 for inserting the plug connector 30 is formed on the upper surface side of the receptacle and wing 21. A plurality of contacts 22 are mounted on the receptacle housing 21 in a state of being spaced apart from each other. Is done. For this reason, as shown in FIG. 1, the receptacle groove and the udging 21 are formed with a fixing groove 24 and a fixing recess 25 for fixing the contact 22 on the lower surface side. Further, the contact force beam 22a, 22b of the contact rod 22 is inserted into the recess 23 from the bottom surface side of the insertion force 26 force diffractor nozzle 21 for passing through the rotation. Further, a groove 23 a for accommodating the contact beams 22 a and 22 b of the contact 22 is formed on the inner wall surface of the recess 23 at the position of each contact 22.

On the inner wall surface of the recess 23, the gap between the adjacent grooves 23a, 23a is such that the distance between the upper part and the inner wall surface on the opposite side of the recess 23 gradually decreases from the top to the bottom. Surface) 23b.

[0025] The contact 22 is formed by stamping a thin plate made of a conductive material such as a copper alloy.

The contact 22 has a pair of contact beams 22a, 22b force S facing each other at a predetermined interval, and has a substantially U shape formed so as to extend upward from the base portion 22c. Further, at one end of the base portion 22c, the receptacle 22 is electrically connected to the contact pattern 22 (not shown) of the printed wiring board 11 with the contact 22 mounted on the receptacle housing 21. A connection portion 22 d is formed that protrudes below the lower surface of the receptacle housing 21 at substantially the same level as the lower surface of the housing 21. In addition, the base ^ 22c (the contact holes facing each other, the outer surfaces of the arms 22a and 22b, the protrusions 22e and 22f inserted into the fixing recesses 25 of the receptacle housing 21 are formed. Has been

[0026] The contact 22 is fixed to the receptacle housing 21 by the base portion 22c being press-fitted into the fixing groove 24 on the lower surface of the receptacle housing 21, and in this state, the protrusions 22e and 22f are fixed to the receptacle housing 21. The recess 25 is inserted. The recess 25 of the receptacle housing 21 and the protrusions 22e and 22f of the contact 22 are respectively formed with recesses 25a and 22g. The protrusions 22e and 22f are inserted into the fixing recess 25 of the receptacle housing 21. Then, the concave portion 25a and the convex portion 22g are engaged with each other. The contact beam 22a, 22b of the contact 卜 22 protrudes upward in the recess 23 in a state where it is mounted on the receptacle housing 21 as described above. It has become so. At this time, the contact beams 22a and 22b are positioned in a groove 23a formed on the inner wall surface of the recess 23.

[0027] The plug connector 30 includes a resin plug housing (second housing) 31 that fits into the receptacle housing 21, and a contact (second contact) 32 made of a conductive material such as a copper alloy. It is configured. Here, the plug connector 30 is arranged so that the electric wire 100 whose end is connected to the contact 32 extends in a direction orthogonal to the fitting direction (insertion direction) of the plug housing 31 with respect to the receptacle housing 21. The cross section is L-shaped.

As shown in FIGS. 1 and 3, the plug housing 31 is formed with a cavity 33 for holding the contact 32. The cavity 33 is formed so that the contact 32 is inserted from the electric wire 100 side in a direction perpendicular to the fitting direction (insertion direction) of the plug housing 31 with respect to the receptacle housing 21.

[0029] A plurality of contacts 32 are arranged at intervals with respect to the plug housing 31 so as to correspond to the contacts 22 of the receptacle connector 20. As shown in FIG. 4, the contact 32 is continuously connected to the barrel portion 34, and the barrel portion 34 includes a wire barrel 34a that is crimped to the end of the wire 100 and an insulation barrel 34b that is crimped to the sheath of the wire 100. And a plate portion (holding portion) 35 that is formed perpendicularly and extends downward perpendicularly to the barrel portion 34 has a shape arranged in an approximately L shape.

[0030] At the upper end of the plate portion 35, a rib portion (holding portion) 36 that is bent so as to be orthogonal to the plate portion 35 is formed. The cavity 33 of the plug housing 31 is formed with a recess 33a and a slit 33b corresponding to the rib portion 36. With these recesses 33a and slits 33b, the movement of the contact 32 in the vertical direction (the direction in which it approaches and separates from the receptacle connector 20) can be regulated between the tip of the rib 36 and the rear end of the barrel 34. The rib portion 36 of the contact 32 has a lance 36c protruding upward. On the other hand, the cavity 33 of the plug housing 31 is opened upward between the recess 33a and the slit 33b, thereby forming a step 33c adjacent to the slit 33b. The lance 36c is connected to the step 33c when the contact 32 is inserted into the cavity 33 of the plug nosing 31. The movement of the contact 32 in the direction of engagement and removal from the cavity 33 is restricted. Further, the movement of the contact 32 in the insertion direction with respect to the cavity 33 is restricted by the interference between the rib portion 36 and the recess 33a.

Here, as shown in FIG. 1, in order to securely engage the lance 36c and the stepped portion 33c, the length L1 from the lance 36c to the tip portion 36a of the rib portion 36 of the contact 32 is determined. However, it is necessary to increase the length L2 from the step 33c of the plug housing 31 to the tip of the recess 33a. As a result, when the contact 32 is inserted into the plug nosing 31, the contact 32 can be moved further in the insertion direction than the position where the lance 36 c and the stepped portion 33 c are engaged. . If there is an error within the allowable range of the dimensions of the contact 32 or plug housing 31, more specifically, when the length L1 from the lance 36c to the tip 36a of the rib 36 of the contact 32 is large within the allowable range This is because the lance 36c is securely engaged with the step portion 33c.

As shown in FIG. 4, contact portions (portions that bear electrical contact) 37 and 38 that are bent so as to be substantially orthogonal to the plate portion 35 are formed below the plate portion 35. . These contact portions 37 and 38 are formed in portions that protrude downward from the plug housing 31 when the contacts 32 are inserted into the cavities 33 of the plug housing 31. That is, in the cavity 33, the portion that accommodates the plate portion 35 is formed in a slit shape, thereby restricting movement of the contact 32 in the lateral direction (direction in which the contacts 32 are arranged). .

The contact portions 37 and 38 are formed in steps so that the positions of the tip end portions 37a and 38a (distance from the fitting surface of the plug housing 31 to the receptacle housing 21) are different from each other. Further, the front end portions 37a and 38a of the contact portions 37 and 38 are bent inward.

As shown in FIG. 1, the plug nosing 31 has a bridge plate for holding the tip of the contact 32 provided so as to protrude downward from the plug nosing 31 as described above. 39a is provided. As shown in FIG. 3, the bridge plate 39a is connected to the plug housing 31 by a support plate 39b disposed between the contacts 32 adjacent to each other. The contact 32 is held by the bridge plate 39a. Can be prevented from bending in the lateral direction (thickness direction of the plate portion 35). Then, the bridge plate 39a and the support plate 39b form a convex portion 39 corresponding to the concave portion 23 of the receptacle housing 21 on the fitting surface side of the plug housing 31 with respect to the receptacle housing 21! /.

[0034] At the lower end of the plate portion 35, a follower plate (guide portion) 40 that protrudes below the tip portions 37a, 38a of the contact portions 37, 38 so as to be continuous with the plate portion 35 in the same plane. 4 1 is formed. Here, as described above, the contact portions 37, 38 are formed so that the positions of the tip portions 37a, 38a (distance from the plug housing 31) are different from each other. Accordingly, the follower plates 40 and 41 are also formed in steps such that the positions of the lower end portions thereof are different from each other from the fitting surface of the plug housing 31 with respect to the receptacle housing 21. The follower plates 40 and 41 are formed such that their side end faces (end faces) 40a and 41a are substantially in the same position as the contact parts 37 and 38 in the width direction of the plate part 35.

As shown in FIG. 1, in such a plug connector 30, the convex portion 39 is inserted into the concave portion 23 formed in the receptacle housing 21. Then, the contact portions 37 and 38 of the contact 32 on the plug connector 30 side face the groove 23 a formed in the recess 23 of the receptacle housing 21, and the plate portion 35 of the contact 32 is on the inner wall surface of the recess 23. It faces between the grooves 23a and 23a adjacent to each other, that is, the position where the guide surface 23b is formed.

Then, as shown in FIG. 5, when the convex portion 39 of the plug connector 30 is further pushed into the concave portion 23, when the contact 32 of the plug connector 30 is displaced toward the contact portion 38, first, the contact is made. The follower plate 41 located below the tip end portion 38 a of the portion 38 hits a guide surface 23 b formed on the inner wall surface of the recess 23 of the receptacle housing 21. When the follower plate 41 hits the guide surface 23b, the contact 32 moves to the contact portion 37 side. On the contrary, when the contact 32 of the plug connector 30 is displaced toward the contact portion 37 side with respect to the plug housing 31, the contact 32 moves to the contact portion 38 side when the follower plate 40 contacts the guide surface 23b. To do.

[0037] As shown in FIG. 6 (a), the position of the contact 32 of the plug connector 30 with respect to the recess 23 formed in the receptacle nosing 21 can be corrected in this way. The contact 32 on the lug connector 30 side can be guided to the correct position between the contact beams 22a and 22b of the contact 22 on the receptacle connector 20 side. As a result, as shown in FIG. 6 (b), if the plug connector 30 is further pushed in, the contact beams 22a and 22b of the contact 22 and the contact portions 37 and 38 of the contact 32 slide smoothly without colliding. Can make contact and make electrical connection. In this state, the contact beam 22a, 22b of the contact 22 elastically pinches the contact rod portions 37, 38 of the contact rod 32 with both side forces. The direction in which the contact 32 between the contact beams 22a and 22b of the contact 22 is sandwiched is coincident with the direction in which the contact 32 has a backlash.

[0038] When the plug housing 31 is completely pushed into the recess 23 of the receptacle housing 21, the receptacle housing 21 and the plug housing 31 are engaged with each other to prevent the plug connector 30 from falling off and to ensure the engaged state. Can be maintained. Any structure may be used as a structure for engaging the receptacle housing 21 with the plug and the louver 31. For example, the protrusion 28 formed on the receptacle housing 21 and the plug housing 31 may be used. A configuration in which the engaging claws 31a are engaged with each other can be employed.

Now, the position of the contact 32 of the plug connector 30 is corrected when the follower plates 40, 41 contact the guide surface 23 b of the receptacle housing 21, not the contact portions 37, 38. Position correction is not performed by striking the contact beams 37a, 22b and the contact beam 22a, 22b of contact 22. For this reason, it is possible to prevent the contact beams 22a and 22b of the contact portions 37 and 38 and the contact 22 from being deformed.

In this way, even if the structure is such that the contact 32 is loose with respect to the plug and the lousing 31, the contact 32 does not collide with the contact beams 37 a and 22 b of the contact 22 and the contact 32 is correctly The contact portions 37 and 38 can be prevented from deforming the contact beams 22a and 22b. In such a configuration, the contact 32 has a mounting structure that uses a lance 36c that is not press-fitted or molded by resin or the like, so that it is easy and low-cost without requiring extra labor, jigs, and equipment. It can be attached to plugnos and woogings 31 and can be manufactured at low cost.

[0040] Further, the follower plates 40, 41 are plate-like located in the same plane as the plate portion 35, and when the side end surfaces 40a, 41a hit the guide surface 23b of the receptacle housing 21 Because the external force acts in the in-plane direction of the follower plates 40 and 41, the follower plates 40 and 41 can exhibit high rigidity and rigidity, and are not easily deformed during position correction.

[0041] Further, since the contact portions 37, 38 of the contact 32 have their tip portions 37a, 38a positioned one above the other, the contact beams 22a, 22b of the contact 22 are in contact with each other one after another to be electrically connected. Connection can be achieved. As a result, even when the plug connector 30 is pushed in by hand, the contact portion 37 first gets a feeling of contact with the contact beam 22a, and then the contact portion 38 comes into contact with the contact beam 22b. The ability to obtain a two-step click feeling is possible. Further, when the plug connector 30 is pushed into the receptacle connector 20, the force that receives the insertion resistance force of the contact 32 is contacted by the follower plates 40 and 41 with respect to the contact 22 on the receptacle connector 20 side as described above. The follower plates 40 and 41, the tip 37a of the contact part 37, and the tip 38a of the contact part 38 are arranged in steps, so that they are simultaneously received on both sides. When the guide surface 23b of the housing 21 or the contact 22 is in contact with the guide surface 23b or the contact 22, the upper follower plate 40 or the tip 37a of the contact portion 37 contacts the guide surface 23b or the contact 22, the lower follower plate 41 and the tip 38a of the contact part 38 are already guided while sliding on the guide surface 23b and the contact 22, so it is necessary for fitting. That force peaks are not concentrated, it can be reduced 揷入 resistance. That is, the plug connector 30 can be easily pushed into the receptacle connector 20.

[0042] In the above embodiment, the receptacle housing 21 has a female housing having a recess 23, and the plug housing 31 has a male housing. Is also possible. Similarly, although the contact 22 of the receptacle connector 20 is a female contact and the contact 32 of the plug connector 30 is a male contact, it is also possible to adopt a configuration in which the male member is replaced with the female member. In that case, the receptacle connector 20 and the plug connector 30 can be configured to have a female housing and male contact or a combination of male housing and female contact.

In addition to the above, the configurations described in the above embodiments can be selected or changed to other configurations as appropriate without departing from the gist of the present invention.
