Abstract

The operation of a lock member and the check thereof are easily and reliably enabled with a simple configuration while achieving downsizing. When a movable lock engagement part is moved along a lock guide part in a state in which a fixed lock latch part provided on either one of first and second electrical connectors is in an arrangement relation that the fixed lock latch part is overlapped with the lock guide part provided on the other one in a mating direction, the movable lock engagement part is engaged with or released from the fixed lock latch part. An operation of engaging or releasing the movable lock engagement part with/from the fixed lock latch part is carried out in a state in which the operation can be visually checked through a housing-operation opening and facing the electrical connectors.

First claim

What is claimed is:

1. A board-connecting electrical connector device for mutually mating a first electrical connector to which a first wiring board is coupled and a second electrical connector to which a second wiring board is coupled to electrically connect the first and second wiring boards with each other,
the board-connecting electrical connector device configured to maintain the first and second electrical connectors in a mutually mated state by mutually engaging lock members provided on insulating housings of the first and second electrical connectors; wherein
the lock member of either one of the first and second electrical connectors has a lock guide part provided on the insulating housing and a movable lock engagement part attached to the lock guide part so as to be able to reciprocate;
the lock member of the other one of the first and second electrical connectors has a fixed lock latch part attached to the insulating housing;
the fixed lock latch part has an arrangement relation that, when the first and second electrical connectors are mutually mated, the fixed lock latch part is overlapped with the lock guide part in the direction of the mating;
the movable lock engagement part is configured to be engaged or released with/from the fixed lock latch part when the movable lock engagement part is moved along the lock guide part from the state in which the fixed lock latch part is overlapped with the lock guide part; and
at least one of the insulating housings of the first and second electrical connectors is provided with a housing-operation opening that brings the movable lock engagement part into an exposed state toward the outer side of the mating direction.

2. The board-connecting electrical connector device according to claim 1 , wherein at least one of the first and second wiring boards is provided with a board-operation opening that brings the movable lock engagement part into an exposed state toward the outer side of the mating direction.

3. The board-connecting electrical connector device according to claim 1 , wherein
the movable lock engagement part is disposed in an inner side of a region in which the electrical connector is mounted with respect to the wiring board.

4. The board-connecting electrical connector device according to claim 1 , wherein
the first and second electrical connectors are provided with a pair of electrode rows consisting of a plurality of contact members aligned in a multipolar manner, and
the movable lock engagement part is disposed between the pair of electrode rows.

5. The board-connecting electrical connector device according to claim 1 , wherein
the fixed lock latch part and the movable lock engagement part are formed by thin-plate-shaped metal members; and
the movable lock engagement part and the fixed lock latch part are provided with mating detection parts consisting of concave/convex parts mutually mated upon the engagement.

6. The board-connecting electrical connector device according to claim 1 , wherein
the movable lock engagement part is configured to be moved along a longitudinal direction of the first and second electrical connectors.

7. The board-connecting electrical connector device according to claim 1 , wherein
a moving range of the movable lock engagement part is regulated by a positioning part integrally formed with the insulating housing so as to be elastically displaceable in the mating direction.
