Electrical connection column

Abstract

The invention relates to an electrical connection column which is formed by integrating an insulation shell, an upper embedded body and a lower embedded body in a hot-casting manner. The upper embedded body is embedded in the upper part of the insulation shell in a reverse screw structure, and a part of appearance of a screw cap of the upper embedded body is of a noncircular structure. The lower embedded body is embedded in the lower part of the insulation shell in a nut structure, and the appearance of a nut of the lower embedded body is of a noncircular structure. A bolt part of the upper embedded body is of an external thread structure, and the external thread part is embedded in the upper part of the insulation shell. The upper part and the lower part of the insulation shell are respectively embedded with the upper embedded body and the lower embedded body in a hot-casting manner, and parts are respectively locked and connected by the upper embedded body and the lower embedded body, thus the electrical connection column disclosed by the invention has a simple and compact structure, small weight, high corrosion resistance, high strength and high plasticity, is firmly connected with the parts, and can meet the requirements on the special performance of aero-products.

Description

technical field [0001] The invention relates to an electrical connection column, in particular to an electrical connection column with high strength and high performance requirements, which is widely used in the aviation field to connect conductors and support components. Background technique [0002] At present, electrical connection columns used in the aviation field need to meet the requirements of light weight, corrosion resistance, high strength, vibration resistance, good plasticity, high strength, and no displacement when tightening when connecting conductors, and not easy to fall off. For example, the connection post disclosed by the patent No. 200920156536.7 is provided with axial screw holes on the upper and lower end surfaces of the metal connection post respectively, and the screws pass through the top plate and the bottom plate respectively and are locked on the connection post. The disadvantages are: the metal material The terminal posts are heavy in weight and...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems of heavy weight and poor corrosion resistance of the connecting post in the prior art, the direct use of screws to tighten the components on the connecting post is easy to loosen and the connection is not firm, etc., the present invention provides a simple structure, light weight, corrosion-resistant High performance, firm connection, not easy to loose electrical connection column
