1. An electrical connection comprising:

  • a. A block having a socket provided with an open end and a closed end, b. a connector in the socket and including;

    i. a pin mounted rigidly with respect to the block and projecting into the socket from the closed end thereof, and ii. resilient contact fingers positioned around the pin and having outwardly flared ends presented toward the open end of the socket, the resilient contact fingers being formed integral with and extended from a common base of substantially the same thickness as the fingers, the base being positioned against the closed end of the socket and being extended inwardly toward the pin so that the pin passes through the base, the base being in electrical contact with the pin where the pin passes through it so that current will be conducted between the pin and the contact fingers;

    c. locking means in the socket and fixed relative to the longitudinal axis thereof and of the pin, the locking means including retention fingers which project inwardly and obliquely relative to the longitudinal axis of the pin and generally toward the pin; and

    d. a mating connector element including i. a barrel having a hollow interior which opens outwardly from the forward end thereof and is sized to receive the pin, the barrel being thicker than the spacing between the opposed contact fingers, whereby when the mating contactor is inserted into the socket the barrel will pass over the pin and will further engage and spread the contact fingers so that the contact fingers will engage the external surface of the barrel, and ii. a shoulder fixed in position relative to the barrel and located such that it will pass beyond the ends of the retention fingers when the mating connector is inserted into the socket, the mating connector at the outer periphery of the shoulder being wider than the spacing between opposed retention fingers, whereby the mating connector will spread the retention fingers as it is inserted into the socket, and thereafter the retention fingers will snap inwardly so that their free ends are disposed opposite to the shoulder and prevent withdrawal of the mating connector from the socket.
