Cap for a high-tension cable terminal for use in an automobile engine

Abstract

A cap is attached to a high-tension cable terminal for sealing an opening formed on an automobile engine. The cap includes a hollow cap body made of rubber and having a cylindrical portion, a hood integrally formed with and extending outwardly from the cap body, and a seal ring securely mounted on the cylindrical portion of the cap body. The seal ring is made of rubber different from the rubber of the cap body and has a high heat resistance and a sufficient elasticity. When the cap is mounted on the opening, the seal ring engages the inner peripheral surface of the opening to provide a seal against dirt, dust and water. Alternatively, the seal ring may be made of rubber of the same quality as the cap body. In this case, the hardness of the seal ring is rendered to be less than that of the cap body.
