Abstract: A reinforced 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 latch arm includes a spring steel wire insert for reinforcement, such that the plastic latch arm does not become permanently deformed. 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.

Abstract: The present invention is structured for preventing a spacer from being dislocated as inserting a terminal to a terminal compartment provided in a terminal connector housing, so that simple and reliable assembly and connection of the connector are made possible, and incomplete insertion of the terminal can be detected at the same time. This in turn improves the efficiency of the work, reduces the load of a worker and also improves the quality of the connector.

Abstract: An electrical connector includes a housing having a terminal-receiving chamber. When a terminal is fully inserted in the chamber, the terminal is lockingly engaged with an elastic retainer arm mounted within the chamber, so that the terminal is prevented from withdrawal from the chamber. A spacer is inserted into the chamber so as to be received in a space formed between the retainer arm and an inner surface of the chamber. The spacer is elastically deformable by the housing when the spacer is inserted into the chamber. The terminal is engageable with the retainer arm to elastically deform the same to reduce the space when the terminal is incompletely inserted in the chamber, so that the spacer in its deformed condition is prevented from being inserted into the space.

Abstract: 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.

Abstract: A connector for transmission cable has a lower housing and an upper housing securable thereto to be terminated to a prepared end portion of the cable. The conductors are laser welded in slots of the terminals. The contact sections of the terminals reside on respective resilient supports of the lower housing which act in cantilever fashion. A hood section of the upper housing extends over the plurality of contact sections to define a cavity. The connector structure is hermaphroditic in that one connector is matable with another identical connector having a reversed vertical orientation. The respective hoods cooperate to resist the forced cantilever action of the pairs of resilient supports urging each other apart, thus generating contact normal force. The hermaphroditic connectors latch when fully mated.
