Connector for making connection with mating interface

A method of making an electrical connection between a conductor and a mating interface including the steps of:

• providing a connector comprising a hollow cylindrical conductor having a longitudinal axis, a member located within the conductor and capable of making a mechanical connection with a mating interface, the conductor and member being relatively movable in the direction of the longitudinal axis, and resilient means being located between the conductor and member;
• moving the member relative to the conductor to place the connector in a first state in which the resilient means applies a force between the conductor and member whilst maintaining the conductor and member in their relative position;
• engaging the member with the mating interface to make a mechanical connection between them;
• and
• then placing the connector in a second state which allows relative movement to occur between the conductor and member such that the resilient means urges them together in an axial direction, whereby an electrical connection is made between the conductor and a component of the mating interface.
