A latch member extends in the mating direction and includes a latch end movable between a latch position in latching engagement with a latching surface on the complementary connector and a release position disconnected from the complementary connector. The latch member includes an actuator end for moving the latch end. A housing of resilient dielectric material is overmolded about portions of the shell and the latch member and includes an integrally molded actuator button for engaging and moving the actuator end of the latch member and, in turn, moving the latch end of the latch member to its release position. The latch member extends axially through a ferrule and is pivotally mounted therewithin. A resilient O-ring is mounted within the ferrule to bias the latch member in its latch position. ## Claims ### Claim 1 An electrical connector, comprising: a shell having a forward connecting section for connection with a complementary connector in a mating direction; a latch member extending in said mating direction and including a latch end pivotable between a latch position in latching engagement with a latching surface on the complementary connector and a release position disconnected from the complementary connector, and an actuator end for moving the latch end; and a housing of resilient dielectric material overmolded about portions of the shell and the latch member and including an integrally molded actuator portion disengaged from the actuator end of the latch member when the latch end is in the latch position, said actuator portion for engaging and moving the actuator end of the latch member and, in turn, moving the latch end of the latch member to its release position. ### Claim 2 (depends on 1) The electrical connector of claim 1 wherein said latch member extends axially through a ferrule and including a pivot pin extending transversely through the ferrule and pivotally mounting the latch member. ### Claim 3 (depends on 1) The electrical connector of claim 1, including means for biasing the latch member in its latch position. ### Claim 4 (depends on 3) The electrical connector of claim 3 wherein said means for biasing comprises a resilient O-ring surrounding the latch member. ### Claim 5 (depends on 4) The electrical connector of claim 4 wherein said latch member extends through a ferrule, and said O-ring is mounted within the ferrule. ### Claim 6 (depends on 1) The electrical connector of claim 1 wherein said latch member comprises a substantially planar member pivotally mounted on a pivot member extending generally perpendicular to the plane of the latch member. ### Claim 7 An electrical connector, comprising: a shell having a forward connecting section for connection with a complementary connector in a mating direction; a ferrule mounted on said shell and extending in said mating direction; and a latch member extending in said mating direction and including a latch end movable between a latch position in latching engagement with a latching surface on the complementary connector and a release position disconnected from the complementary connector, and an actuator end for moving the latch end, the latch member extending axially through said ferrule and including a pivot pin extending transversely through the ferrule and pivotally mounting the latch member. ### Claim 8 (depends on 7) The electrical connector of claim 7 wherein said latch member comprises a substantially planar metal member with said pivot pin extending therethrough generally perpendicular to the plane of the latch member. ### Claim 9 (depends on 8) The electrical connector of claim 8, including an O-ring mounted within the ferrule for biasing the latch member toward its latch position. ### Claim 10 An electrical connector, comprising: a shell having a forward connecting section for connection with a complementary connector; a latch member pivotable about a fulcrum between a latch position in latching engagement with a latching surface on the complementary connector and a release position disconnected from the complementary connector; a housing of resilient dielectric material overmolded about portions of the shell and the latch member and including an integrally molded actuator portion for engaging and moving the latch member to its release position; and a rigid tab extending from said latch member toward engagement with a resilient portion of said connector for biasing the latch member toward the latch position. ### Claim 11 (depends on 10) The electrical connector of claim 10 wherein said latch member extends axially through a ferrule, and including a pivot pin extending transversely through the ferrule to pivotally mount the latch member. ### Claim 12 (depends on 10) The electrical connector of claim 10 wherein said latch member extends through a ferrule and said resilient portion for biasing the latch member comprises a resilient O-ring mounted within the ferrule. ### Claim 13 An electrical connector, comprising: a housing; a latch member mounted on the housing for movement between a latch position in latching engagement with a latching surface on a complementary connector and a release position disconnected from the complementary connector; and a resilient O-ring fixed relative to the housing and surrounding a movable portion of the latch member for biasing the latch member in its latch position. ### Claim 14 (depends on 13) The electrical connector of claim 13 wherein a tab projects from said latch member and engages the O-ring.
