Description

  The present invention relates to an electrical connector provided with a lock mechanism that can hold or release a connection fitting state between a pair of connectors.

  In general, electrical connectors configured to connect and fit a pair of connectors are widely used in various electrical devices. In a normal electrical connector, a signal transmission medium such as a cable, FPC, or FFC is connected to one connector, for example, a plug connector, and on the printed wiring board provided with an electronic circuit or the like, the other connector, For example, a receptacle connector is mounted, and a plurality of signal lines and ground lines constituting a signal transmission medium are connected to the electronic circuit side by connecting and fitting the two connectors together.

  As described above, when the pair of connectors are connected and fitted, there is a risk that both the connected connectors are disconnected depending on the board layout around the connectors and the cable routing state. For this reason, conventionally, a lock mechanism that holds the connector in a connected state may be provided. For example, a lock member is provided on the first connector so as to be elastically displaceable, and a lock receiving member is provided on the second connector. The locking member on the first connector side is fitted to the lock receiving member on the second connector side to maintain the connected fitting state between the two connectors. When the two connectors in the connected and fitted state are separated from each other, the lock member on the first connector side is detached from the lock receiving member on the second connector side so that the two connectors can be released.

  Here, the lock member provided on the first connector side described above is configured to be elastically displaced, for example, so as to ride on the cam member, and the lock member elastically displaced by the action of the cam member is provided. When the lock member on the first connector side is moved away from the cam member, the lock member is moved away from the cam member when the lock member on the first connector side is moved away from the cam member. The lock member is opened to be restored and the lock member is fitted to the lock receiving member in the restored state.

  However, the lock member is elastically displaced by the cam member or the like so as to be detached from the lock receiving member, and the elastically displaced lock member is restored to be engaged with the lock receiving member. In this locking mechanism, there is a possibility that the operation of displacement or restoration of the lock member, that is, the operation of fitting or disengaging from the lock receiving member may be hindered.

  For example, in the case where the lock member is formed of a rotation operation lever member, the operation lever member as the lock member is pulled outward when the connectors are pulled out. It is conceivable that plastic operation is generated in the rotation operation lever member and the lock receiving member when the connector is pulled out through the connector. If even a slight plastic deformation occurs in the pivoting lever member or the like, the lock member may not be restored, that is, the fitting to the lock receiving member may not be performed well, and the lock operation may be incomplete. .

  In general, the cam member described above is often formed of a resin member integrated with the housing, and therefore, it is considered that the cam member is worn by contact with the lock member formed of a metal member. There is a possibility that the separation, that is, the unlocking may not be performed.

It is made to the structure performed until the fitting position by which it was brought down in the substantially horizontal state to the side. When the lock lever 14 is flipped up to the upper release position as shown in FIG. 1, a spring-like holding piece formed so as to cut out a part of the conductive shell 13 of the plug connector 1 ( The locking lever 14 is moved to the release position by engaging a part of the locking lever 14 with a holding projection (not shown) formed so as to protrude a part of the insulating housing 11. It may be temporarily fixed.

  Further, the torsion spring portions 14b and 14b described above are formed by bending both end portions in the longitudinal direction of the operation main portion 14a into a substantially L-shape in front, and each of the torsion spring portions 14b and the lock member 14c. Are provided so as to extend in the rotational radius direction of the lock lever 14. Each of the torsion spring portions 14b can elastically displace the locking member 14c described above by twisting deformation, and the rotating arm portion 14d is moved inward in the longitudinal direction by a lock pressing member 25 described later. When the torsion spring portion 14b is pressed toward the side, the torsion spring portion 14b undergoes torsional deformation, and the lock member 14c described above becomes the shaft of the lock member 14c along with the elastic deformation mainly of torsional deformation of the torsion spring portion 14b. It is made the structure displaced toward the inner side of the longitudinal direction which is an extending direction.

  Further, a position restricting portion 14e that temporarily holds the lock lever 14 in the fitting position is formed at a substantially central portion in the longitudinal direction of the operation main portion 14a of the lock lever 14 described above so as to have an appropriate width in the longitudinal direction. Has been. The position restricting portion 14e is formed so as to protrude stepwise toward the outer side of the turning radius of the lock lever 14, and the insulating housing 11 provided corresponding to the position restricting portion 14e. By engaging with the position restriction receiving portion 11a, the entire lock lever 14 is temporarily held at the fitting position.

  On the other hand, the receptacle connector (second connector) 2 described above is provided with a lock receiving member 24 to which the lock member 14c on the plug connector (first connector) 1 side is fitted or removed. The lock receiving members 24 are respectively provided at both end portions in the longitudinal direction of the connection fitting convex portion 2a. The connection fitting convex portion 2a is formed so as to extend in an elongated shape along the longitudinal direction at the substantially central portion in the front-rear direction of the insulating housing 21 described above, and has a substantially rectangular cross section. As described above, a part of the plurality of conductive terminals (contacts) 22 arranged in a multipolar array is exposed on the outer surface.

  The lock receiving members 24 provided at both ends in the longitudinal direction of the coupling fitting convex portion 2a have holes 24a that open toward the outer side in the longitudinal direction of the coupling fitting convex portion 2a. Yes. As shown in FIG. 7 in particular, each of the holes 24a is disposed so as to be aligned with and face the inner end of the locking member 14c on the plug connector (first connector) 1 side described above. The inner end portion of the lock member 14c is configured to be insertable or detachable from the outer side to the inner side of the hole 24a as shown in FIG. Has been.

  When the inner end portion of the lock member 14c is inserted into the hole 24a as shown in FIG. 10, both the members 14c and 24a are in a fitted state and the connectors 1 and 2 are connected and fitted. Will be held. On the other hand, when the lock member 14c is pulled out from the fitting state between the lock member 14c and the hole 24a of the lock receiving member 24 and removed, the connectors 1 and 2 are connected to each other. The connection fitting state is not maintained, and the state is shifted to a state where it can be released and removed.

  Here, by inserting the lock member 14c on the plug connector (first connector) 1 side with respect to the hole 24a of the lock receiving member 24 on the receptacle connector (second connector) 2 side as described above, and by removing it. The detachment is performed by the interaction between the lock pressing member 25 and the lock lever 14 as described below. The lock pressing member 25 is erected on both end portions in the longitudinal direction of the front end edge portion of the receptacle connector 2, and the lock member 14 c of the plug connector 1 is provided on the inner side surface of the lock pressing member 25. The locking member 14c is displaced or restored by contact or separation.

  The lock pressing member 25 is formed by bending a part of the conductive shell 23 of the above-described receptacle connector (second connector) 2 so as to protrude upward in a columnar shape, and is connected to the receptacle connector 2. The plug connector (first connector) 1 is arranged in the vicinity of the outer position so as to be erected. Then, as shown in FIG. 11A, the lock lever 14 provided on the plug connector 1 is rotated on the inner surface side portion of the lock pressing member 25, that is, on the surface facing the plug connector 1. A lock guide surface 25a made of an inclined surface that can come into contact with the arm portion 14d and that forms a substantially “cross-sectional” vertical section protruding toward the plug connector 1 is provided.

  That is, the above-described lock guide surface 25a includes an inclined surface portion in which the protruding amount toward the plug connector 1 side (inward side) continuously increases from the substantially flat uppermost end surface portion downward. In addition, a flat vertical wall surface portion is erected at a position slightly depressed from the lower end top portion of the inclined surface portion at a portion below the lower end top portion of the inclined surface portion. And the rotation arm part 14d of the lock lever 14 arrange | positioned along the vertical wall surface part is latched by the lower end top part of the inclined surface part mentioned above.

  Here, when the connectors 1 and 2 are connected and fitted as described above, first, after the lock lever 14 on the plug connector (first connector) 1 side is disposed at the release position on the upper side, both connectors 1 and 1 are connected. As shown in FIG. 5, the two are connected and fitted in the vertical direction. Then, the rotation operation is performed so that the operator pushes the lock lever 14 in the release position while pushing it down, and when the lock lever 14 is rotated to the fitting position in FIG. The rotating arm portions 14d and 14d thus brought into contact with the inclined surface portion of the lock guide surface 25a of the lock pressing member 25 on the receptacle connector (second connector) 2 side described above.

  Then, as the turning operation of the lock lever 14 further proceeds, the turning arm portions 14d, 14d of the lock lever 14 slide on the inclined surface portion of the lock guide surface 25a of the lock pressing member 25, and the lock lever 14 is locked. The rotating arm portions 14d and 14d are held when the lower end top portion of the inclined surface portion of the guide surface 25a is overcome, that is, in the fitting position. (See FIG. 11 (b)) At this time, the operator who operates the lock lever 14 feels a click when the rotating arm portions 14d and 14d get over the lower end top of the inclined surface, and the lock lever 14 is in the fitting position. Can be confirmed.

  Then, when such a rotation operation of the lock lever 14 is performed, an inward pressing force is applied from the lock guide surface 25a of the lock pressing member 25 to the rotation arm portions 14d and 14d of the lock lever 14. The lock members 14c and 14c are inserted into the holes 24a and 24a of the lock receiving member 24 as shown in FIG. To be made. The rotating arm portions 14 d and 14 d arranged at the fitting position are locked by a substantially U-shaped portion provided in the lock guide surface 25 a of the lock pressing member 25. In this way, when the lock member 14c on the plug connector 1 side is fitted into the hole 24a of the lock receiving member 24 on the receptacle connector 2 side, the connected fitting state between the connectors 1 and 2 is maintained.

  On the other hand, as described above, the operator operates the lock lever 14 on the side of the plug connector (first connector) 1 in the mating position so as to push it up while grasping it, thereby releasing the FIG. 5 from the mating position in FIG. When the lock lever 14 is rotated in the direction of the position, the rotating arm portions 14d and 14d provided on both side portions of the lock lever 14 are connected to the lock pressing member 25 on the receptacle connector (second connector) 2 side. Separated from the lock guide surface 25a. As a result, the lock lever 14 is restored to its original state by its own elasticity, and the lock members 14c and 14c are separated outward from the holes 24a and 24a of the lock receiving member 24 as shown in FIG. Then, when the lock member 14c on the plug connector 1 side is detached from the hole 24a of the lock receiving member 24 on the receptacle connector 2 side, the connected fitting state between the connectors 1 and 2 is not maintained and can be released. It is transferred to.

  As described above, in the present embodiment, the receptacle connector (second connector) 2 is brought into contact with or separated from the rotating arm portions 14d and 14d of the plug connector (first connector) 1 so as to lock the members 14c and 14c. A lock pressing member 25 that displaces or restores the lock pressing member 25 is provided, and the lock members 14c and 14c are fitted in the hole 24a of the lock receiving member 24 in a state of being displaced in contact with the lock pressing member 25, A configuration is adopted in which the lock receiving member 24 is detached from the hole 24a in a state where the lock pressing member 25 is separated and restored.

  Further, the conductive shell 23 of the receptacle connector (second connector) 2 is provided with a hold-down portion 23a soldered on the printed wiring board at a portion immediately below the lock pressing member 25 and in the vicinity thereof. The hold-down portion 23a forms a ground circuit with the conductive shell 23 interposed therebetween, and the receptacle connector 2 is firmly supported as a whole.

  According to the electrical connector of the present embodiment having such a configuration, the plug connector (first connector) is inserted into the hole 24a of the lock receiving member 24 provided on the receptacle connector (second connector) 2 side. ) When the lock member 14c on one side is fitted, the lock member 14c is surely elastically displaced by coming into contact with the lock pressing member 25. Therefore, it is assumed that some deformation occurs in each part when the connector is removed. In addition, the fitting of the lock member 14c to the hole 24a of the lock receiving member 24, that is, the locking operation is performed satisfactorily. Further, once the lock member 14c is fitted into the hole 24a of the lock receiving member 24, the lock release is smoothly performed by elastic restoration of the lock member 14c itself. Accordingly, the reliability of the engagement or disengagement operation of the lock member 14c is improved.

  In addition, the lock lever 14 as the lever-like member according to the present embodiment includes the torsion spring portion 14b that allows the lock member 14c to be elastically displaced by twisting. Therefore, due to the twisting elastic force in the torsion spring portion 14b, In particular, the restoration of the lock member 14c is favorably performed, and the reliability of the detachment operation of the lock member 14c is further improved.

  Furthermore, the lock pressing member 25 provided in the receptacle connector (second connector) 2 in the present embodiment has an inclined surface portion that forms a substantially cross-sectional shape that protrudes toward the plug connector (first connector) 1 side. Therefore, the lock lever 14 arranged at the fitting position is locked by the substantially U-shaped portion of the lock pressing member 25, and the lock lever 14 is connected and fitted between the two connectors 1 and 2. It becomes possible to hold | maintain in the fitting position which hold | maintains a state, and the reliability of holding | maintenance of the connection fitting state of both the said connectors 1 and 2 is improved. Further, when the operator operates the lock lever 14 from the release position to the fitting position, the user feels a click when the lock lever 14 gets over the apex of the inclined surface portion that forms a substantially U-shaped longitudinal section. Can be confirmed to be held at the fitting position.

  Furthermore, in this embodiment, since the lock pressing member 25 provided on the receptacle connector (second connector) 2 side is formed of a metal material, wear of the lock pressing member 25 is prevented, and the plug connector ( (1st connector) The fitting operation | movement with the locking member 14c of the 1 side is maintained smoothly over a long term.

  Furthermore, in this embodiment, since the lock lever 14 rotated to the fitting position is temporarily held by the position restricting portion 14e, the state in which the lock lever 14 has been rotated to the fitting position is maintained in advance. The connectors 1 and 2 are connected and fitted stably.

  In the present embodiment, when the lock lever 14 is turned to the fitting position in advance when the connectors 1 and 2 are connected and fitted, the turning arm portion 14d of the lock lever 14 moves from the lock guide surface 25a. When a pressing force is applied, the distal end portion of the lock member 14c protrudes toward the coupling fitting convex portion 2a and contacts and interferes with the coupling fitting convex portion 2a. However, when the connectors 1 and 2 are connected and fitted together, the locking arm 14d of the lock lever 14 is not pressed against the lock guide surface 25a. The front end portion of the member 14c does not protrude toward the connection fitting convex portion 2a, and the connectors 1 and 2 can be connected and connected. For this reason, when the connectors 1 and 2 are connected and fitted, the lock lever 14 does not necessarily have to be placed at the release position on the upper side. May be.

  Next, in the second embodiment of the present invention shown in FIGS. 12 and 13 in which the same components as those in the first embodiment of the present invention described above are denoted by the same reference numerals, a lock lever is provided in advance. At least one of a lock guide portion 2b and a lock guide portion 14f is provided for enabling the connectors 1 and 2 to be connected and fitted together while the connector 14 is rotated to the fitting position. That is, when the plug connector (first connector) 1 is pushed into the receptacle connector (second connector) 2 side in a state where the lock lever 14 is pivoted to the fitting position in advance, the pivot arm portion 14d is moved to the lock guide. A pressing force is applied from the surface 25a, and the distal end portion of the lock member 14c protrudes toward the connection fitting convex portion 2a described above, and thus contacts and interferes with the connection fitting convex portion 2a. Therefore, the lock guide portion 2b which guides the tip end portion of the lock member 14c to a position where there is no hindrance to the connection fitting and permits the connection fitting of both the connectors 1 and 2 is connected to the connection fitting convex portion 2a, and the lock guide portion. 14f is provided at the tip of the lock member 14c.

  At this time, the lock guide portion 2b on the side of the coupling fitting convex portion 2a is formed from inclined surfaces obtained by cutting off both end portions in the longitudinal direction of the coupling fitting convex portion 2a into corners, as shown in FIG. When the lock lever 14 on the side of the plug connector 1 is rotated to the fitting position and the connectors 1 and 2 are connected and fitted together, the lock guide portion 2b The inclined surfaces are in contact with each other. Further, the lock guide portion 14f on the lock lever 14 side is provided at the distal end portion of the lock member 14c, and when the connectors 1 and 2 are connected and fitted in a state where the lock lever 14 is rotated to the fitting position. It is formed from the inclined surface which cut off the side which faces the connection fitting convex part 2a.

  Then, when the connection fitting between the connectors 1 and 2 proceeds in a state where the lock lever 14 is pivoted to the fitting position in advance, the tip portions of the lock members 14c and 14c come into contact with the inclined surfaces of the lock guide portions 2b and 2b. Alternatively, the inclined surface of the lock guide portion 14f is in contact with the corner portion of the coupling fitting convex portion 2a, or the inclined surfaces of the lock members 14c and 14c are in contact with the inclined surfaces of the lock guide portions 2b and 2b.
