Patent number: 5376025Abstract: A fitting for halogen lamps of the type having plural contact pins has an insulating socket with a recess for each contact pin. Each recess confines a pivotable and reciprocable plate-like contact which is connected to a conductor and is biased by a coil spring to engage an abutment of the socket and to define therewith a wedge-like path for insertion of a contact pin. The contacts are hinged to the socket adjacent the inlets of the respective recesses, and the insertion of a contact pin into its recess results in a composite pivotal and translatory movement of the respective contact away from the adjacent abutment. The major part of the inserted contact pin is clamped between the contact and the abutment.Type: GrantFiled: July 23, 1992Date of Patent: December 27, 1994Assignee: Bender & Wirth GmbH & Co.Inventors: Helmut Willnat, Hans D.
