Abstract
An electrical coupling device for connecting separable connecting leads between at least two switchrooms is in particular for medium voltage switchgears, the connecting leads being passed through container walls and surrounded, in each case, by a rotationally symmetrical insulating body, the insulating bodies being surrounded by an insulating collar that is common to both, the connecting leads being connected by a contact device in an electrically conductive manner. Lead-in pins are provided on front-form sides with a multi-contact which acts as an annular contact body for receiving a contact pin. The contact pin is configured in one piece and is also spherical in the area of the multi-contact. The contact pin is surrounded by a sleeve, which in the longitudinal middle area of the contact pin is configured so as to curve inward and is connected to the sleeve in an electrically conductive manner. The degree of freedom in the angular, lateral, and axial area is compensated for using this electrical coupling device. Electrical coupling devices of this type are employed in medium voltage switchgears.
