Description

  The present invention relates to an electrical connector and an electrical connector device having a lock mechanism for holding a signal transmission medium inserted in an insulating housing.

  In general, various electrical connectors are widely used as means for electrically connecting various signal transmission media such as a flexible printed circuit (FPC) and a flexible flat cable (FFC) in various electrical devices. It is used. For example, in an electrical connector that is mounted and used on a printed wiring board as in Patent Document 1 below, a signal transmission medium made of FPC, FFC, or the like is inserted into the inside from an opening on the front end side of an insulating housing (insulator). Thereafter, the actuator (connection operation means) is rotated so as to be pushed down toward the connection operation position on the front side or the rear side of the connector by the operator's operation force. As a result, a part of the lock member falls into the engagement portion provided in the terminal portion of the signal transmission medium to be engaged, and the terminal portion of the signal transmission medium is held in a substantially immovable state by the lock member. Has been made.

  As described above, the electrical connector provided with the actuator is configured to operate engagement / disengagement of the lock member by rotating the actuator between the connection release position and the connection operation position. Since it is necessary to operate the actuator separately from the operation of inserting a medium (FPC, FFC, etc.), the work efficiency may be a problem. Therefore, for example, as described in Patent Documents 2 and 3 below, the signal transmission medium inserted into the insulating housing is elastically displaced so that a part of the lock member rides on, and then the signal transmission medium is engaged. Conventionally, an electrical connector having a so-called one-action auto-lock mechanism, which is configured such that a part of a lock member falls into a part and engages, has been developed. If an electrical connector equipped with such a one-action auto-lock mechanism is used, the signal transmission medium can be held in a substantially stationary state simply by inserting the signal transmission medium to a predetermined position inside the electrical connector. Is improved.

  However, the one-action auto-locking mechanism employed in the conventional electrical connector has an advantage that locking is performed only by inserting a signal transmission medium (FPC, FFC, etc.) into the electrical connector as described above. There is a tendency that the configuration of the unlocking operation part for releasing the engagement state of the locking part tends to be complicated, and it takes time to perform the releasing operation, and there is a possibility of causing a problem in durability.

The wiring pattern Fa provided on the signal transmission medium F is obtained by arranging connection terminal portions including signal transmission conductive paths (signal line pads) or shield conductive paths (shield line pads) at appropriate pitch intervals.

  Here, the configuration of each conductive contact 12 will be described in detail. The conductive contacts 12 are arranged along the connector front-rear direction, which is the insertion / removal direction of the signal transmission medium F (the left-right direction in FIG. 5). The stationary beam 12a and the movable beam 12b are extended. The fixed beam 12a and the movable beam 12b are connected to the connector front side (in FIG. 5) from the lower end position and the upper end position of the connecting column 12c arranged to extend in the vertical direction at the rear end of the connector of the insulating housing 11. It protrudes substantially parallel to the left side.

The terminal contact convex portion 12e provided on the conductive contact 12 has a wiring pattern Fa provided on the signal transmission medium F when the signal transmission medium F is inserted into the insulating housing 11 as described above. When the signal transmission medium F is inserted to a predetermined final position, the terminal contact convex portion 12e is pressed onto the wiring pattern Fa by the elastic force of the movable beam 12b and electrically connected. The connection is maintained.

[About locking mechanism]
The electrical connector 10 according to the present embodiment includes the one-action auto-lock mechanism as described above, and the lock mechanism RM includes a lock engaging member RM1 disposed on the insulating housing 11 side, and a signal transmission. It consists of a lock engaging member RM2 attached to a terminal portion of a medium (FPC or FFC) F.

  Among them, the lock engaging member RM2 has a lock member Fb formed of a thin metal plate, and the lock member Fb is on the lower surface side of the terminal portion of the signal transmission medium (FPC or FFC) F. It is attached in close contact. That is, a pair of hook portions Fc and Fc are formed at predetermined positions on the metal plate constituting the lock member Fb so as to correspond to the hook portions Fc and Fc. A pair of mounting fixing holes Fd and Fd are formed through both sides of the signal transmission medium F in the width direction. The hooks Fc and Fc provided on the lock member Fb side are inserted so as to be hooked from below on the mounting fixing holes Fd and Fd provided on the signal transmission medium F side. The lock member Fb is fixed to the lower surface side of the base plate in a superposed state. The mounting fixing hole Fd provided on the signal transmission medium F side may have a notch shape.

  Further, as another fixing method of the lock member Fb and the signal transmission medium F, the lock member Fb in the state of a protruding piece extending upward is formed without performing horizontal bending at the hook portion Fc of the lock member Fb. The lock member Fb formed of the upward projecting piece is inserted so as to penetrate the mounting fixing hole Fd of the signal transmission medium F from below, and then the locking member protrudes upward from the mounting fixing hole Fd. It is also possible to fix by bending the protruding piece of Fb in the horizontal direction and pressing the signal transmission medium F.

  Thus, in a state where the lock member Fb is attached to the terminal portion of the signal transmission medium (FPC, FFC, etc.), both side portions of the lock member Fb are stretched outward from both ends in the width direction of the signal transmission medium F. The lock portions Fe and Fe, which will be described later, are provided on the protruding portions on both sides of the lock member Fb so as to be elastically displaceable. Further, narrow lock insertion holes 11c and 11c are formed in both side portions of the medium insertion port 11a in the width direction (connector longitudinal direction) corresponding to the both-side protruding portions of the lock member Fb. Each of these lock insertion holes 11c is provided in communication with the medium insertion port 11a.

  At the same time, the overlapping portion of the signal transmission medium F and the lock member Fb is inserted inward along the medium insertion path extending from the medium insertion port 11a toward the back side of the insulating housing 11. The protruding portions on both sides of the lock member Fb are configured to be inserted inward along the lock insertion passage extending from the lock insertion holes 11c and 11c toward the back side of the insulating housing 11.

  Further, lock portions Fe and Fe formed in a key shape are provided on both side protruding portions of the lock member Fb described above via flexible elastic arms Ff and Ff. Each elastic arm Ff is formed by notching a part of the protruding portion on both sides of the lock member Fb described above into a shape that is elongated in the longitudinal direction of the connector, from the front side portion of the lock member Fb to the connector rear side. It extends so as to form a cantilever. And by having such a cantilever structure, the said elastic arm Ff is made into the structure which can be rock | fluctuated elastically to an up-down direction.

  The lock portion Fe described above is provided at the tip portion in the extending direction (the connector rear side) of each elastic arm Ff having such a configuration. The lock portion Fe moves the tip portion of the elastic arm Ff upward. It has an integrated structure that is bent into a protruding mountain shape. As described above, the lock portion Fe formed integrally with the elastic arm Ff is configured to be elastically displaced in the vertical direction simultaneously with the swinging of the elastic arm Ff, and more specifically, particularly in FIG. As shown, it has a step engagement surface Fe1 that rises substantially perpendicularly from the elastic arm Ff, and an inclined guide surface Fe2 that extends obliquely rearward from the top of the step engagement surface Fe1.

  On the other hand, corresponding to the step engagement surface Fe1 and the inclined guide surface Fe2 provided in such a lock portion Fe, a lock locking member RM1 that is also a part of the lock mechanism is provided inside the insulating housing 11 described above. A step locking surface 11d and an inclined guide surface 11e are provided so as to constitute the above. A step locking surface 11d and an inclined guide surface 11e provided on the insulating housing 11 as the lock locking member RM1 are formed on the upper surface side of the lock insertion passage extending rearward from the lock insertion hole 11c described above.

  That is, first, the inclined guide surface 11e is provided corresponding to the inclined guide surface Fe2 of the lock portion Fe constituting the lock engagement member RM2, and the lock insertion passage extends from the lock insertion hole 11c. It is comprised by the inclined surface formed in the front side area | region. More specifically, the inclined guide surface 11e gently inclines the wall surface of the insulating housing 11 forming the upper surface of the lock insertion passage obliquely downward toward the connector rear side (right side in FIG. 5). It is formed by letting.

  Then, at the initial stage when the insertion of the signal transmission medium (FPC or FFC or the like) F is started, the lock portion Fe provided as the lock engagement member RM2 on the signal transmission medium F side is insulated as the lock engagement member RM1. It contacts the inclined guide surface 11e provided in the housing 11 from the front side of the connector. Accordingly, the signal transmission medium F is inserted while being elastically displaced so that the lock portion Fe is pressed downward against the elastic return force of the elastic arm Ff.

  Similarly, the step engaging surface 11d provided on the insulating housing 11 so as to constitute the lock engaging member RM1 is provided corresponding to the step engaging surface Fe1 of the lock portion Fe as the lock engaging member RM2. It is formed by a standing wall surface of a slit hole 11f that forms a lock release arm 11g described later.

  That is, the upper side wall portion of the insulating housing 11 forming the lock insertion passage described above is formed so that the slit hole 11f penetrates in the vertical direction at a position slightly away from the inclined guide surface 11e toward the connector rear side. Has been. A pair of slit holes 11f are provided at both end portions of the insulating housing 11 in the longitudinal direction of the connector so as to extend in a substantially U-shape on the plane, and an unlocking arm is provided on the inner side of each slit hole 11f. 11g is arranged to be swingable in the vertical direction. The unlocking arm 11g will be described in detail later. In particular, as shown in FIG. 6, among the substantially U-shaped standing wall surfaces constituting the slit hole 11f described above, of the front side of the connector. By the standing wall surface, the above-described step locking surface 11d is formed to extend substantially upward at a right angle from the upper wall surface of the lock insertion passage.

  Then, the signal transmission medium (FPC or FFC or the like) F is inserted into the electrical connector 10 up to the final position, and the step engagement surface Fe1 of the lock portion Fe constituting the lock engagement member RM2 is locked. When passing through the step locking surface 11d of the insulating housing 11 constituting the locking member RM1, at the same time, as shown in FIG. 9, for example, the step engaging surface Fe1 of the lock portion Fe is moved to the lock portion. It is elastically displaced so as to be pushed upward along the step locking surface 11d by the elastic return force of the elastic arm Ff supporting Fe. As a result, the step engaging surface Fe1 of the lock portion Fe is in contact with the step engaging surface 11d of the insulating housing 11 from the rear side of the connector, thereby locking the signal transmission medium F in the connector front-rear direction. It becomes a state.

  On the other hand, as described above, the slit holes 11f of the lock engaging member RM1 are formed so as to penetrate the upper wall portion of the insulating housing 11 in the vertical direction so as to surround the lock release arm 11g. Each of the unlocking arms 11g arranged on the inner side of each of the slit holes 11f is arranged so as to be opposed to both end portions in the connector longitudinal direction. Each of these unlocking arms 11g extends in a cantilevered manner from both end portions of the insulating housing 11 in the connector longitudinal direction toward the inner side of the connector, and is elastic in the vertical direction with both end portions in the connector longitudinal direction as fulcrums. Is configured to be swingable.

  Moreover, the unlocking operation part 11h which protrudes in the up-down both directions from the said unlocking arm 11g is provided in the front-end | tip part in the extension direction (connector inner side) of each of these unlocking arms 11g. The unlocking operation portion 11h provided integrally with the unlocking arm 11g is configured to be elastically displaced in the vertical direction as the unlocking arm 11g swings. As shown in FIG. 9, the unlocking operation unit 11h is arranged when the insertion of the signal transmission medium (FPC or FFC or the like) F is completed, that is, above the lock unit Fe in the locked state. The relationship is made.

  In addition, a flange-like portion 11i that protrudes in a substantially horizontal direction is formed at the upper end portion of the unlocking operation portion 11h, and the flange-like portion 11i extends so as to cover the slit hole 11f described above from above. Exist. The flange-like portion 11i is maintained in a state slightly spaced upward from the upper surface of the insulating housing 11 in a state where the unlocking operation portion 11h is not operated. However, the unlocking operation portion 11h is lowered by the operator. When pushed in, the flange-like portion 11i of the unlocking operation portion 11h comes into contact with the upper surface of the insulating housing 11, thereby restricting the downward movement of the unlocking arm 11g.

  In particular, when the unlocking operation unit 11h is pushed downward from the locked state of the signal transmission medium (FPC or FFC or the like) F shown in FIG. 9, the unlocking is performed as shown in FIG. The lower end surface of the operation portion 11h pushes down the step engagement surface Fe1 of the lock portion Fe against the elastic return force of the elastic arm Ff described above, whereby the step engagement surface Fe1 of the lock portion Fe is reduced. Then, the signal transmission medium F is released from the stepped locking surface 11d on the insulating housing 11 side, the lock state of the signal transmission medium F is released, and the signal transmission medium F is shifted to a state where it can be removed.

  As described above, according to this embodiment, the lock engaging member RM2 including the lock portion Fe of the lock mechanism conventionally provided on the electric connector side is arranged on the signal transmission medium (FPC or FFC or the like) F side. Because of the structure, the structure of the electrical connector 10 is simplified correspondingly, and a reduction in size or height can be easily realized. Further, since the signal transmission medium F is reinforced by the lock member Fb of the lock engaging member RM2 attached to the signal transmission medium F side, electrical connectivity and durability in use are improved.

  In particular, in this embodiment, the lock member Fb can be easily attached to the terminal portion of the signal transmission medium (FPC, FFC, etc.) F by the hooking operation of the hook portion Fc to the attachment fixing hole Fc formed in the signal transmission medium F. To be done.

  Further, in the lock engagement member RM2 according to the present embodiment, the lock portion Fe is provided at the tip portion of the elastic arm Ff made of a cantilever member, so that the lock portion Fe is supported so as to be elastically displaceable. Is simplified.

More specifically, a flange-like portion 11i ′ protruding substantially horizontally from the upper end portion of the unlocking operation portion 11h ′ is substantially on the upper surface of the insulating housing 11 in the initial state before the signal transmission medium F is inserted. It is kept in contact.

  In the second embodiment as described above, substantially the same operational effects as those of the first embodiment described above can be obtained. That is, when the signal transmission medium F is inserted into the electrical connector 10 to the final position, the lock portion Fe moves upward due to the elastic return force of the elastic arm Ff supporting the lock portion Fe, and thereby the lock portion. The step engaging surface Fe1 of Fe abuts on the step engaging surface 11d on the insulating housing 11 side, and the signal transmission medium F is maintained in the locked state.

  At this time, particularly in the present embodiment, the unlocking operation part 11h ′ is also moved upward as the lock part Fe rises, so that the signal transmission medium F is inserted through the upward movement of the unlocking operation part 11h ′. Completion of is easily and reliably confirmed visually from above.

  Although the invention made by the present inventor has been specifically described based on the embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. Needless to say.
