摘要

The igniter (100) has a plastic made pole structure (104) that is connected with an outwardly closing cap (122) that is made of plastic with linear chain structure, or crosslinked structure. The plastic is a linear polyphenylene sulfide, cross-linked polyphenylene sulfide or glass-fiber reinforced polyamide, such that glass fiber content in plastic is about 50%. An end wall of the cap is made of softer plastic material than a circumferential wall of the cap.
