Multi-point contact finger and electrical connector

Abstract

The invention provides a multi-point contact finger and an electrical connector containing the multi-point contact finger. The multi-point contact finger comprises a bracket, a plurality of recessed sheets, and watchband-shaped sheets that are equal to the recessed sheets in number. The plurality of recessed sheets are fixed on the bracket at interval. The recessed sheets are provided with positioning slots. The watchband-shaped sheets are provided with positioning blocks. The watchband-shaped sheets are arranged on the recessed sheets by the cooperation of the positioning blocks and the positioning slots. The bracket is made of steel, the recessed sheets are made of steel, and the watchband-shaped sheets are made of red copper. According to the invention, elastic and structural support isprovided through the steel bracket and the recessed sheets, the watchband-shaped sheets are used as a conductive body. While ensuring the service life of the machine provided in the invention, the electrical performance of the multi-point contact finger is greatly improved, and the rated flow capacity is improved.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a multi-point contact finger and an electrical connector. Background technique [0002] In the current technology, the contact fingers are used in the field of power systems and plugs, and mainly serve as conductive connections in power transmission and transformation lines. In power systems and plug devices, the specific structure types of plug contacts are varied. According to whether there is relative motion at the contact point during operation, the contacts are divided into three categories: sliding connection, static connection and plug-in connection. When the plug is closed, there is usually sufficient pressure between the contacts by the tension or compression of the contact fingers. [0003] The core component in the plug-in electrical connector is the multi-point contact finger, while the existing multi-point contact finger is made of beryllium bronze, w...

AI Technical Summary

Problems solved by technology

[0003] The core component in the plug-in electrical connector is the multi-point contact finger, while the existing multi-point contact finger is made of beryllium bronze, which is about 21% of the flow capacity of pure copper, and the heat dissipation capacity is about 28% of pure copper. %, therefore, the multi-point contact fingers of beryllium bronze limit the rated current capacity of the electrical connector

On the electrical connector with a diameter of 16mm, the rated current capacity of the electrical connector with multi-point contact fingers made of beryllium bronze is 530A. When a single electrical connector is used, it cannot meet the use environment where the rated current of domestic transformer outlets exceeds 630A.
