Abstract: An electrical connector device comprises an isolating support 20 and a conductive capsule 21 accessible from the exterior of the connector and fixed to the support 20 by a deformable membrane 22. The support 20, the membrane 22 and the capsule 21 define a cavity 23 at the bottom of which is a pole 24. Without connection to an associated contact, the capsule 21 is isolated from the pole 24. At the time of connection to said associated contact, the associated contact depresses the capsule 21 to establish the electrical contact with the pole 24. In particular, this connector device is useful between vehicle components that require frequent removal and reattachment where electrical signals are transmitted across the interface.
