Abstract
The invention relates to an electrical contact for an electrical plug connection, said contact having a flexible element between a connecting region fixed in a housing and a movable contact region. In the electrical contact, the movement of the contact region and/or the deformation of the flexible element in the direction of an axis extending parallel to the plugging direction of the contact region is/are limited. Such contacts are provided in particular in power sockets for motor vehicles for creating an electrical connection to a trailer.
Claims10
An electrical contact comprising a round cross section for an electrical plug connection, said electrical contact being mounted within a housing and having a flexible element between a connecting region and a movable contact region wherein:
- the connecting region is fixed in the housing within an overmolding or by means of press-fitting,
- the contact region comprises one of an electrical pin or a socket contact, the electrical pin or socket contact having a continuous and water tight combination of surfaces between the flexible element and the connecting region formed from a tubular face and an end face, the tubular face including or enclosing the flexible element, the flexible element with or without the contact region being enclosed in a portion of the housing comprising a sleeve;
- movement of the contact region and deformation of the flexible element along an axis parallel to a plugging direction of the contact region is significantly limited or prevented by at least one stop, but movement and deformation in any direction orthogonal to the plugging direction is possible,
- the electrical contact is designed in one piece,
- the electrical contact is stamped and the combined surfaces of the tubular face and end face of the electrical pin or socket contact and/or housing form a continuous and water tight surface set and create a hollow space which contains the flexible element that allows a sleeve to be formed around the flexible element with or without the contact region, through an overmolding process or a press fit to obtain a flexible element with or without the contact region, enclosed within the sleeve such that the electrical pin or socket contact does not allow a molding compound to enter within a hollow space inside the electrical pin or socket contact during the overmolding process and the hollow space containing the flexible element with or without the contact region is preserved if the electrical pin or socket contact is installed in the housing by means of a press fit, thus allowing movement of the flexible element inside of the hollow space and/or sleeve,
- said flexible element is designed in a form of a coil spring or said flexible element being designed in a form of two orthogonal leaf springs.
