  • Patent number: 5259780
    Abstract: A separable connector for electrically coupling two portions of multiple-conductor cable is disclosed. The connector, in a connected state, is held together by operation of the novel shape of the connector halves. The two connector halves, which each include therein a plurality of metallic contact strips, are identical and "gender neutral", such that any two connector halves may be coupled together. Connection of the connector halves is accomplished by pushing the two halves together; disconnection is accomplished by pulling them apart. When connected, continuous electrical contact is maintained between contact strips in each respective half. The connector is constructed of molded plastic, and includes rubber strain relief collars for preventing fatigue and failure of the attached portions of multiple conductor cable.
