Abstract An electric connector with a double locking mechanism for connecting the electrical conductors of electric circuits on a vehicle. The electric connector with a double locking mechanism comprises a male connector provided with a locking arm having a locking projection, a female connector housing provided with a slot for receiving the locking projection of the locking arm for primary locking when the male connector housing and the female connector housing are joined perfectly together, a locking slider mounted on the female connector housing for sliding movement toward and away from the male connector housing between a first position and a second position, and a spring basing the locking slider to the releasing position. When the male and female connector housings are joined perfectly together, the locking projection is received in the slot of the female connector housing and engages the female connector housing for primary locking. The locking slider is able to engage the first or second connector housing for secondary locking only when the male and female connector housings are joined perfectly together. Thus, the male and female connector housings are locked double when perfectly joined together. When the male and female connector housings are joined imperfectly, the locking slider is unable to stay at the second position and is returned automatically to the first position by the spring.
An electric connector with a double locking mechanism, comprising: a first connector housing; a second connector housing to be mated with the first connector housing; primary locking means provided between said first connector housing and said second connector housing to lock said first connector housing and said second connector housing when said first connector housing and said second connector housing are fully engaged; a locking slider mounted on said second connector housing slidably in axial directions and biased rearwardly, said locking slider being adapted to be temporarily latched to said second connector at a first position; and secondary locking means for locking said locking slider to said first connector housing at a second position forwardly of said first position when said first connector housing and said second connector housing are fully engaged.
