There is provided a connector. A lock arm is connected at a leading end-side and a rear end-side of a housing, supported at both ends thereof along an insertion/pulling out direction with respect to an opposite connector housing, and elastically deformable with the connection parts with the housing serving as fulcrums. A locking claw is formed at the lock arm and locked into a locking hole of the opposite connector housing when inserting the housing into the opposite connector housing. The lock arm has a lock release part which releases a locked state of the locking claw to the locking hole by being pressed toward the rear end-side beyond the locking claw. A position of the fulcrum at the rear end-side is arranged at an opposite side to a protruding direction of the locking claw, compared to a position of the fulcrum at the leading end-side.
1. A connector comprising:
a housing configured to be inserted to and pulled out from an opposite connector housing;
a lock arm connected at a leading end-side and a rear end-side of the housing, supported at both ends thereof along an insertion/pulling out direction with respect to the opposite connector housing and configured to be elastically deformable with the connection parts with the housing serving as fulcrums, the lock arm including an upper surface and
a locking claw formed at the upper surface of the lock arm and configured to be locked into a locking hole of the opposite connector housing when inserting the housing into the opposite connector housing,
wherein the lock arm has a lock release part configured to release a locked state of the locking claw to the locking hole by being pressed and disposed at a position closer to the rear end-side of the housing than the locking claw, and
wherein the fulcrum at the rear end-side of the housing is arranged further away from the upper surface of the lock arm compared to the fulcrum at the leading end-side of the housing.
2. The connector according to claim 1 , wherein a line passing through the respective fulcrums of the lock arm is arranged so as to be substantially perpendicular to a direction of a pressing force to be applied to the lock release part.
3. The connector according to claim 1 , wherein
a distance between a fulcrum line passing through the fulcrums and a central axis line of the housing becomes smaller as a position on the fulcrum line gets closer to the rear-end side.
