General embedded-type high-tension line assembly

Abstract

The invention discloses a general embedded-type high-tension line assembly belonging to automobile parts. A tubular mount support is buckled by two semicircular pipe bodies via a fastener and a cassette, and the inner wall of the pipe body is provided with a groove; the outer part of the side jacket of a tubular spark plug is provided with a convex rib on the position corresponding to the mount support groove; the side jacket of the spark plug is in plug-in mounting with the mount support; and the convex rib is horizontally arranged in the groove; and the bottle neck of the mount support is sheathed with an upper cover dust cover and a seal ring. The invention has the following beneficial effects: 1. the assembly height of the side jacket of the spark plug can be adjusted, can be used in 100-130 mm engines and has convenient adjustment, simple operation and wide application range; 2. the upper cover dust cover and the seal ring are fixed by internal diameter locking force, do not need adhesive and do not fall off and discharge at high pressure under glue failure; and 3. the invention has simple die, short development time, small funding input and low cost.

Description

technical field [0001] The invention belongs to an automobile accessory, in particular to a general-purpose embedded high-voltage line assembly. Background technique [0002] At present, the high-voltage line assembly generally has: 1. The exposed type of multi-piece assembled resin post; 2. The outer type of multi-piece assembled resin post. The former type is prone to electrical performance degradation due to long-term use of resin post in high-temperature environments. In the end, breakdown discharge and engine abnormality are caused; the latter adds a silicone sheath to the outside of the resin rod to increase the long-term use time of the product in a high-temperature environment and ensure the long-term high-temperature use of the product's electrical performance, but the manufacturing cost is relatively high; moreover, the above-mentioned The two assembled high-voltage wire assemblies have stricter requirements on the assembly size of each component in the production ...

Problems solved by technology

[0002] At present, the high-voltage line assembly generally has: 1. The exposed type of multi-piece assembled resin post; 2. The outer type of multi-piece assembled resin post. The former type is prone to electrical performance degradation due to long-term use of resin post in high-temperature environments. In the end, breakdown discharge and engine abnormality are caused; the latter adds a silicone sheath to the outside of the resin rod to increase the long-term use time of the product in a high-temperature environment and ensure the long-term high-temperature use of the product's electrical performance, but the manufacturing cost is relatively high; moreover, the above-mentioned The two assembled high-voltage wire assemblies have stricter requirements on the assembly size of each component in the production process of semi-finished products, which increases the inspection cost in the production process, the assembly cost also increases correspondingly, and the assembly process is also cumbersome. In addition, multiple There are also hidden dangers in the overall quality of the product. Multi-piece assembly is likely to cause poor bonding, causing the sheath to fall off, causing high-voltage discharge due to unglue, and there is a hidden danger of assembly height after assembly; The overall strength, 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 decline in electrical properties

According to the use status of its products and considering the actual situation of materials at home and abroad, the applicant improved the overall structure, and applied for the embedded high-voltage live wire assembly in 2008. The application number is 200820142229.9. This patent overcomes the limitations of the above two assembly methods. Defects, one-time injection molding, excellent performance and stable quality, but different molds need to be developed according to different heights of engine assembly, product mold development costs are high, and silicone needs to choose materials with higher tear strength, so cost is also high
