Embedded type high tension live wire assembly

Abstract

An embedded high-voltage ignition wire assembly consists of two insert jackets and a high-voltage ignition wire, wherein a lug is arranged outside the insert jacket; an exhaust groove is arranged on the bottom of the lug; a concaveness is arranged inside the insert jacket; a metal inserter is inserted in one of two insert jackets, and one end of the metal inserter is provided with a gibbosity and clamped with the concaveness inside the insert jacket; and the high-voltage ignition wire is inserted in the metal inserter, and is tightly pressed and fixed by the metal inserter. The embedded high-voltage ignition wire assembly has the advantages that a gel-casting forming avoids the dropping and glue failure of the jackets and potential troubles caused by the whole height, and ensures the safety of use at high temperature for a long time; the metal inserter is strong enough to be inserted; and the structure is simple and the stability is increased.

Description

technical field [0001] The invention relates to an automobile part, in particular to an embedded high-voltage ignition wire assembly. Background technique [0002] At present, the high-voltage ignition wire assemblies used by major domestic OEMs all adopt multi-piece assembly methods. During the production process of semi-finished products, the requirements for the assembly size of each component are more stringent, which relatively increases the cost of inspection in the production process and the cost of the assembly process. Corresponding increase, the process operation is more cumbersome, including the bonding of both ends of the sheath and the height detection after bonding; the Japanese embedded high-voltage ignition wire assembly removes the small sheath and improves it into a whole sheath in terms of the original hard pipe connection sleeve , Wrap the hard pipe connection sleeve in the rubber sheath to improve the overall electrical performance, but the corresponding...

AI Technical Summary

Problems solved by technology

[0004] 1. Single-piece assembly is to bond the rubber sheaths at both ends to the middle hard tube, which may easily cause poor bonding to cause the sheath to fall off, and high-voltage discharge due to glue opening, and there is a hidden danger of assembly height after assembly;

[0005] 2. The sheath adopts a hard tube connection method to meet the overall strength during insertion, but the product has been in a high temperature state for a long time, which has caused the molecular changes of the product material, resulting in a decrease in electrical performance
