Cigarette lighter insert with electrical rejuvenation contact tip

摘要

An insert for a cigarette lighter socket includes a body and a contact rejuvenation tip protruding from and non-rotatable relative to the body. The contact rejuvenation tip includes abrasive elements on its surface for contacting an electrical contact in a cigarette lighter socket. In a preferred embodiment, the abrasive elements are pyramidal in shape and situated on an end surface of the contact rejuvenation tip. The abrasive elements scrape off electrically insulating material on an electrical contact in a cigarette lighter socket as the contact rejuvenation tip is rotated relative to the contact in the cigarette lighter socket. The insert includes a flexible strip attached to the body for resiliently centering a part of said body and said contact rejuvenation tip within said cigarette lighter socket.
