Abstract
A female housing (21) has a rear side formed with a lever pocket (25). A cover (40) has a projection (48) that can be mounted into the lever pocket (25) along with a lever (60). The lever 60 has a cantilevered elastic latch (66) with a latch projection (68) that can engage a mateable latch (49) on the projection 48. The lever (60) has an engaging projection (69) that is opposed to a release rib-advancing slot (36) and adapted to receive a releasing rib (16). When the housings (11) and (21) are coupled to each other into a given depth, the releasing rib (16) enters the slot (36) and engages the engaging projection (69). Thus, the elastic latch (66) retracts elastically toward an escape space (67) and releases a locking condition between the latch projection (68) and the mateable latch (49).
Claims11
A lever type connector assembly including first and second connector housings having front ends and rear ends and being detachably coupled to each other at the front ends thereof, a lever having a cam groove, and an attaching member rotatably supporting said lever, said attaching member being mounted on the rear end of the second connector housing, cam pins on the first connector housing engaging said cam groove in said lever, said connector housings being regularly coupled to each other when said lever is turned from a coupling start position to a coupling completion position, said lever type connector assembly being characterized in that:
- said attaching member is provided with a projection that protrudes in a coupling area in the second connector housing;
- one of said projection and said lever being provided in said coupling area with an elastic latch that can restrain said lever in the coupling start position from turning to the coupling completion position by engaging said elastic latch with a mateable latch portion on the other of said projection and lever;
- and
- the first connector housing being provided with a release portion that releases said elastic latch from said mateable latch by engaging said release portion with said elastic latch when the first connector housing is advancing in said coupling area, thereby elastically deforming said elastic latch to disengage said elastic latch from said mateable latch.
A lever type connector, comprising:
- a first housing having opposite front and rear ends and having a first cam means;
- a second housing having opposed front and rear ends, the front end of the second housing being mateable with the front end of the first housing;
- a cover mounted to the rear end of the second housing and having a projection projecting toward the front end of the second housing;
- a lever mounted to the cover for movement between a coupling start position and a coupling completion position, said lever having a second cam means engageable with the first cam means on the first housing for mating the first and second housings in response to movement of the lever to the coupling completion position, an elastic latch on the lever, the elastic latch being locked with the projection and holding the lever in the coupling start position;
- and
- releasing means on the first housing and engageable with the elastic latch when the front end of the first housing engages the front end of the second housing for deflecting the elastic latch away from the projection and enabling the lever to move to the coupling completion position.
