Abstract
Abstract Electrical connection device comprising two connection elements of which one is mobile, and which are arranged to be capable of mutually coupling and uncoupling by rotation of the mobile element in the other element and to connect or reciprocally separate the opposing contacts with which they are provided. The mobile element is a coupler socket and the other element a connector outlet. The outlet is provided with a protective element which covers the contacts of the outlet when at rest, and which is rotationally mounted therein so as to be capable of being rotationally driven by the coupler socket during coupling. The protective element comprises two flaps which can slide with respect to one another and which are each provided with at least as many openings as there are contacts in the outlet and which are arranged in the same manner. The flaps are positioned with respect to one another when at rest, so that the openings are mutually offset, and means being provided to drive the sliding of the flaps with respect to one another during coupling.
