1. A method of connecting a pin to a housing of a connector with a connect force, which is less than a disconnect force to disconnect the pin from the housing said method comprising:

  • providing the housing with a bore and a housing groove, said housing groove comprising a bottom surface and a release surface that forms an angle to the bottom surface, wherein said angle between said bottom surface and said release surface is between 5° and

    89°

    ;

    providing a coil spring for use with the housing, said coil spring comprising a major axis, a minor axis, and a passage in between two coil sections;

    providing the pin with a longitudinal axis, a tapered end, and a pin groove comprising a groove bottom surface and a load surface that forms an angle to the groove bottom surface, which is less than ninety degrees;

    wherein the connect force is controlled by selecting the major axis of the coil spring to have a concave orientation to the longitudinal axis of the pin when the pin is moved in a first direction relative to the housing to connect the pin to the housing;

    wherein the disconnect force is controlled by selecting the angle of the release surface to bottom surface and the angle of the load surface to groove bottom surface that cooperate to force the major axis of the coil spring to rotate from a first position relative to the longitudinal axis to a second position relative to the longitudinal axis upon removing the pin in a second direction relative to the housing, which is opposite the first direction, to disconnect the pin from the housing; and

    wherein the disconnect force is at least one time greater than the connect force.
