Abstract
Abstract This invention pertains to a lamp socket assembly for use in automotive applications and the like. The assembly includes a housing, a contact insert, and a body. The contact insert is captured in the cavity of the housing by the body. The body is welded to the housing. Lugs on the body secure the assembly to a panel. A seal is placed between a flange on the housing and the panel to seal the assembly to the panel. Contacts are retained in the contact insert by engagement of U-shaped portions in slots of the contact inserts. Blade terminals are inserted through windows in the housing, contact insert, and contacts to interlock the terminals with the contacts and to keep the contacts secured in their positions. A socket connector is sealingly secured to the housing and prevents moisture from entering the housing. In an alternative embodiment, no socket connector is provided but the blade terminals are crimped to wires for connecting the socket assembly to a source of electric power. In still another embodiment, the socket connector includes a protrusion for interlocking the body and the base together.
