Description

Electrical connector

The present invention relates to an electrical connector which is constructed by holding an end portion of a signal transmission medium into a predetermined position inside the insulating casing and utilizing an elastic engaging force of the locking member to hold the signal transmission medium.

In general, various electronic devices and the like are widely used as means for electrically connecting various signal transmission media such as a flexible printed circuit (FPC) or a flexible flat cable (FFC). Use a variety of electrical connectors. For example, in the electrical connector used for mounting on a printed wiring board, a signal transmission medium made of an FPC or an FFC is inserted from the front end side opening portion of the insulating case (insulator) to the inside. Thereafter, the actuator (connection operation means) is rotated in such a manner as to be pushed down by the operator's operating force toward the connection action position on the front side or the rear side of the connector. Thereby, one of the locking members is dropped into the engaging portion provided at the end portion of the signal transmission medium to be in an engaged state, and the end portion of the signal transmission medium is held substantially in a non-moving state by the locking member. .

As described above, the electrical connector including the actuator is configured to rotate and operate the actuator between the connection release position and the connection action position, thereby forming and disengaging the operation lock member, but there is a necessity for signal transmission. The insertion operation of the medium (FPC, FFC, etc.) individually operates the actuator, resulting in work efficiency becoming a problem. Therefore, for example, Patent Documents 2 and 3 below Conventionally, it has been conventionally developed to have an electrical connector having a so-called one-action auto-locking means, which is constructed in such a manner that one of the locking members is inserted into the Elastic displacement is performed by means of a signal transmission medium inside the insulating case, and then one of the locking members is configured to be engaged with the engaging portion of the signal transmission medium. When such an electrical connector having a single-action automatic locking means is used, only the signal transmission medium is inserted into a predetermined position inside the electrical connector, and the signal transmission medium can be kept substantially stationary, and the operation is performed. Increased efficiency.

However, the single-action automatic locking means which is conventionally used for an electrical connector has the advantage of being locked only by inserting a signal transmission medium (FPC, FFC, etc.) into the electrical connector as described above, but another On the other hand, the configuration of the lock release operation portion for releasing the engagement state of the lock lock portion tends to be complicated, and the release operation is laborious and has a problem in use durability.

In the case of the overall miniaturization, the length of the lock arm member 12g can be sufficiently ensured in a small space. Therefore, the operation force of the lock release operation portion 12e provided at the free end position can be suppressed to be small. On the other hand, by arranging the locking locking portion 12a in the vicinity of the bent portion 12g1, it is possible to secure a large holding force of the locking locking portion 12a.

In addition, the state in which the signal transmission medium (FPC, FFC, etc.) F is inserted is in a hold state, and the lock release operation portion 12e and the lock lock portion 12a are simultaneously exposed from the notch portion 11c of the insulating case 11 and In the case where the insulative housing 11 is provided with the notch portion 11c that exposes the lock release operation portion 12e to the outside, the insertion of the signal transmission medium F is insufficient, and the lock release operation portion is not provided. The 12e can be maintained in a state of being buried from the notch portion 11c of the insulating case 11 to the inside, and the insertion operation of the signal transmission medium F can be easily determined.
