Description

  The present invention relates to an electrical connector having a configuration in which a fitting state with a mating connector is held by a fitting holding member.

  In general, in various electric devices and the like, it is widely performed to transmit an electric signal sent through various signal transmission media to an electronic circuit on a wiring board via an electric connector mounted on the wiring board. More specifically, a mating connector to which a terminal portion of a signal transmission medium such as a coaxial cable, a flexible printed circuit (FPC), or a flexible flat cable (FFC) is connected is mounted on a wiring board. The contact is inserted from the insertion opening of the electrical connector toward the inward fitting space, and the terminal portion of the signal transmission medium is disposed inside the electrical connector via the contact member or directly. A signal circuit is formed by being in a fitted state so as to contact the member.

  In this way, when the mating connector to which the terminal portions of various signal transmission media are connected is brought into the fitted state, the fitting attached to the mating connector is rotatably attached in order to maintain the mated state of the mating connector. Conventionally, a configuration in which the mating holding member (pull bar) is rotated and a part of the fitting holding member is engaged with the main body of the electrical connector to prevent the mating connector from falling off is often employed. ing.

  For example, in the following prior art document 1 (Japanese Patent Laid-Open No. 2013-041680), a plug connector (mating connector) is fitted to a receptacle connector mounted on a wiring board, and then provided on the plug connector. The fitted holding member (pull bar) is rotated from the standby position to the operating position, and the edge portion of the fitted holding member is engaged with a part of the receptacle connector. Then, the plug connector, which is the mating connector, is connected to the receptacle connector fixed to the wiring board via the fitting holding member rotated to the operating position, and the two electrical connectors are not dropped off. It is held in a possible state.

  Here, as described above, the receptacle connector is firmly fixed by the wiring board, but since the plug connector is held by interposing a fitting portion with the receptacle connector, the fitting is performed. It is in a state having a backlash corresponding to a gap generated in the portion and a manufacturing error. Therefore, when the fitting holding member (pull bar) is attached to the plug connector (mating connector) as in the conventional electrical connector device, the component accuracy of the fitting holding member, its mounting accuracy, and the engagement accuracy Even if it improves, there exists a possibility that the fitting state of both electrical connectors may not be stabilized from the backlash of the fitting part mentioned above. On the other hand, in order to stabilize the fitting state between the two electrical connectors, a configuration in which the length of the portion in which the two electrical connectors are fitted is also conventionally employed, but in that case, The entire electrical connector device tends to be enlarged, and may not be able to meet the recent demand for miniaturization.
