A positive latch structure for electrical connectors is provided. The latch structure comprises at least one latch on one connector in a mateable pair which is resiliently deflectable about a first axis and which is disposed to contact a cam on the opposed connector during mating. The deflectable latch and/or the cam on the opposed connector define a leading ramp surface, a trailing ramp surface and a locking surface. The leading ramp surface is disposed to resiliently deflect the latch arm and develop stored energy therein. The trailing ramp surface employs the stored energy developed in the latch arm to urge the connectors toward a fully mated condition. The locking surface engages a corresponding surface on the cam to lockingly retain the connectors in their fully mated condition. The connectors may be disengaged from one another by biasing the latch arm about a second axis away from the associated connector a sufficient amount to clear the cam and enable disengagement of the connectors.
A pair of mateable electrical connectors for achieving positive latching in a fully mated condition of said connectors, said pair comprising first and second connectors, the first connector comprising at least one latch resiliently and alternatively deflectable about each of two angularly aligned axes of deflection, the second connector comprising a cam disposed for engagement with said latch during mating of said connectors, at least one of said latch and said cam comprising a leading ramp surface for deflecting said resilient latch about said first axis of deflection thereof and for developing stored energy in said resilient latch, a trailing ramp surface for employing the stored energy of the resiliently deflected latch and urging said connectors into a fully mated condition and a locking surface for lockingly retaining said connectors in a fully mated condition, said latch being deflectable about said second axis of deflection lying substantially in a root which unitarily connects said watch to said first connector disengagement of said latch from said cam for facilitating unmating of said connectors.
A pair of mateable electrical connectors for facilitating and achieving positive releasable locking of said connectors in a fully mated condition thereof, said pair comprising first and second connectors, the first connector comprising a pair of latch arms, each said latch arm being resiliently deflectable about a first axis, the second connector comprising a cam disposed for engagement with said latch arms during mating of said connectors, said latch arms each comprising a leading ramp surface for engaging said cam during mating of said connectors and for resiliently defecting said latch arms about the respective first axes thereof, a trailing ramp surface on said latch arms angularly aligned to said leading ramp surface for employing the stored energy of the resiliently deflected latch arms and for urging said connectors into a fully mated condition, a locking surface on said latch arms for lockingly engaging said cam and retaining said connectors in a fully mated condition, said latch arms being resiliently deflectable about said second axis, lying substantially in a root which unitarily connects said pair of latch arms to said first connector enable disengagement of the locking surfaces of said latch arms from said cam for facilitating unmating of said connectors.
A pair of mateable electrical connectors for facilitating and achieving positive locking of said connectors in a fully mated condition thereof, said pair of connectors comprising a first connector and a second connector, the first connector and a second connector, the first connector comprising a pair of latch arms, each said latch arm being resiliently deflectable about a first axis towards and away from the other latch arm, said latch arms being alternatively deflectable about a second axis extending generally orthogonal to the first axis, each said latch arm comprising a locking surface extending generally parallel to the first axis of said latch arm, the second connector in said pair comprising a generally prismatically configured cam of generally pentagonal cross section, said cam comprising a pair of leading ramp surfaces for deflecting said latch arms about said first axis and for developing stored energy in said latch arms, a pair of trailing ramp surfaces for employing the stored energy of the resiliently deflected latch arms and for urging said connectors into a fully mated condition and a locking surface for lockingly engaging the locking surfaces of said latch arms for retaining said connectors in a fully mated condition, the leading ramp surfaces, the trailing ramp surfaces and the locking surface of said cam being aligned generally parallel to the first axes of said latch arms, whereby the resilient deflection of said latch arms about said second axis lying substantially in a root which unitarily connects said latch arms to said first connector enables disengagement of said latch arms from said cam for enabling unmating of said connectors.
