火花塞高压导线端头
摘要：
本发明公开了一种火花塞高压导线端头。该火花塞高压导线端头包括：金属内管，以及套设在金属内管外的端头内胶套和套设在端头内胶套外的端头外胶套；端头内胶套的材质采用聚四氟乙烯，端头外胶套为硅橡胶管。该火花塞高压导线端头结构简单合理，通过在硅橡胶端头外胶套与金属内管之间设置聚四氟乙烯端头内胶套，大幅提高高压导线的耐热性和抗老化性，能够适应火花塞长期工作温度。
摘要（英）：

The invention discloses a high-voltage wire terminal block of a spark plug. The high-voltage wire terminal block of the spark plug comprises a metal inner tube, a terminal block inner rubber case sleeving the metal inner tube, and a terminal block outer rubber case sleeving the terminal block inner rubber case, wherein the terminal block inner rubber case is made of polytetrafluoroethylene, and the terminal block outer rubber case is a silicon rubber tube. The high-voltage wire terminal block of the spark plug is simple and reasonable in structure and greatly improves the thermal resistance and the ageing resistance of high-voltage wires by arranging the polytetrafluoroethylene terminal block inner rubber case between the silicon rubber terminal block outer rubber case and the metal inner tube, thereby being applicable to long-time working temperature of the spark plug.
