Title: Latched connector and sliding latch keeper
Inventor: HAMAI TSUYOSHI
IPC: H01R13/64
Filed: 1996-11-27
Abstract: A connector A has a resilient latch structure 1 with a latch protrusion 1b for retention by a sliding latch keeper 3 mounted on the housing 8 of a counterpart B. Blocking protrusions 1c of the latch 1 engage stopper protrusions 8a of the counterpart body 8 upon initial mating to prevent the latch from bending into the keeper, thereby causing the latch 1 to push the keeper 3 and slide the keeper 3 on the body 8 against the bias of springs 4. When the blocking protrusions 1c have moved past the stopper protrusions 8a, the force of the springs 4 returns the keeper 3 which causes the latch firstly to depress and then to resile back to be retained by its latch protrusion 1b within the keeper 3. This can only occur when the connectors are properly mated. The latch and keeper structure is resistant to accidental release.
