Patent ID: 7114983

Claim:
A connector, comprising: first and second housings connectable with each other along a connecting direction; an interlocking portion provided on the first housing; a resiliently deformed lock arm provided on the second housing, the lock arm being configured to be deformed in a deformation direction by sliding contact with the interlocking portion during connection of the housing, the deforming direction and the connecting direction being angularly aligned to one another and defining a plane, the lock arm being restored resiliently to engage the interlocking portion when the housings are connected properly; and a substantially linear partial sliding contact area provided on at least one of the lock arm and the interlocking portion for substantially sliding line contact with a mating facing surface on the other of the lock arm and the interlocking portion during connection, the substantially linear partial sliding contact area being in the plane defined by the connecting direction and the deformation direction whereby frictional resistance between facing surfaces of the lock arm and the interlocking portion during the connecting process is reduced.
