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.
