Abstract
A connector has male and female housings (10, 40) that are connectable with one another. A moving plate (30) is movable in the male housing (10) from a first position to a second position during the connection process. A resistance arm (36) on the moving plate (30) must deflect to pass an abutting surface (21) on the male housing (10) during connection, and a lock arm (46) on the female housing (40) must deflect to pass a locking section (25) of the male housing (10) during connection. Resistance forces for deflecting the resistance arm (36) and the lock arm (46) reach peaks substantially simultaneously and before terminal fittings of the housings (10, 40) engage.
Claims20
A connector, comprising:
- a first housing (10) with terminal fittings (17);
- a moving member (30) movable between a first position (FIGS. 2;
- 4) and a second position (FIG. 5) relative to the first housing (10);
- a second housing (40) connectable with the first housing (10) while moving the moving member (30) at the first position toward the second position;
- inertial locking means (51) in the first and second housings (10, 40) for creating a resistance force (Ra) against a connecting operation of the housings (10, 40) by abutting against each other during connection of the two housings (10, 40) and for canceling resistance by disengaging from each other when a resistance canceling force (F) exceeding the resistance force (Ra) created by the inertial locking means (51) is given;
- and
- resistance creating means (52) in the first housing (10) and the moving member (30) for abutting against each other to create a resistance force (Rb) against a movement of the moving member (30) toward the second position with the moving member (30) located at the first position and for canceling resistance by disengaging from each other when a resistance canceling force (F) exceeding the resistance force (Rb) created by the resistance creating means (52) is given;
- wherein the second housing (40) is opposed to the moving member (30) at the first position for pushing the moving member (30) toward the second position while being held substantially in contact with the moving member (30) with the inertial locking means (51) held in abutment against each other and the resistance creating means (52) held in abutment against each other.
