High-power split type dustproof and moisture-proof electrical connector with good contact performance

Abstract

The invention relates to an electrical connector, and particularly relates to a high-power split type dustproof and moisture-proof electrical connector with good contact performance. The high-power split type dustproof and moisture-proof electrical connector with good contact performance comprises a male plug and a female plug, wherein the male plug and the female plug are internally provided witha male plug current-carrying piece and a female plug current-carrying piece which are connected in a split mode and correspondingly suitable for being connected in an inserted mode respectively, andthe male plug current-carrying piece and the female plug current-carrying piece are inserted into a male plug shell and a female plug shell which are correspondingly matched respectively; the male plug shell and the female plug shell adopt a split structure and are respectively designed into a male plug front shell and a female plug front shell, and a male plug rear shell and a female plug rear shell. The electrical connector has the advantages that when the positive and negative current-carrying pieces in the male plug and the female plug are inserted, the coaxiality with smaller errors is achieved, it is guaranteed that the contact precision of the current-carrying pieces in the male plug shell and the female plug shell is better, and the dustproof and moisture-proof functions are achieved.

Description

technical field [0001] The invention relates to an electrical connector, in particular to a high-power split type dust-proof, waterproof and vapor-proof electrical connector with good contact performance. Background technique [0002] China Patent No. 201920132499.X, Invention Name: A high-power split-type electrical connector with good contact. In actual use, the following problems were found in this patent: 1. Due to the male and female plug housings and their inner cavities The connection structure with one-way positioning elastic card is integral injection molding. During the production and manufacturing process of this structure, due to its complex structure and production process, the produced male and female plug products have current-carrying power during mutual insertion. The coaxiality accuracy error of the parts is relatively large, which cannot ensure the ideal contact accuracy after the male and female plugs are plugged together; Insertion is realized, and the ...

[0002] China Patent No. 201920132499.X, Invention Name: A high-power split-type electrical connector with good contact. In actual use, the following problems were found in this patent: 1. Due to the male and female plug housings and their inner cavities The connection structure with one-way positioning elastic card is integral injection molding. During the production and manufacturing process of this structure, due to its complex structure and production process, the produced male and female plug products have current-carrying power during mutual insertion. The coaxiality accuracy error of the parts is relatively large, which cannot ensure the ideal contact accuracy after the male and female plugs are plugged together; Insertion is realized, and the rear end is open, which cannot be dustproof and waterproof for the inner cavity of the male and female plugs, so the above problems need to be solved
