High-current connector

Abstract

The invention discloses a high-current connector which is high in current-carrying capacity and low in temperature rise and has a hot-line operation protection function. According to the technical scheme, the high-current connector comprises a plug and a socket which are matched in an inserted mode, the plug comprises a plug shell body and an adapter bar arranged in the plug shell body, the socket comprises a socket shell body and a current terminal arranged in the socket shell body, and after the plug is connected with the socket in an inserted mode, the adapter bar is connected with the current terminal through first locking screws at the front end, an upper cover is hinged to the upper end of the plug shell, a first spring is arranged at the hinged position, a short-circuit piece is arranged at the lower end of the upper cover, at least two signal terminals are arranged in the socket, when the upper cover is closed, the short-circuit piece enables the two signal terminals to be in short circuit. And when the upper cover is opened, the short-circuit piece is far away from the signal terminals.

Description

technical field [0001] The invention belongs to the field of new energy electric vehicles, and in particular relates to a high-current connector. Background technique [0002] A connector is also called a connector, a device that connects two active devices and transmits current or signals. The connector is composed of a socket and a plug mated with the socket. The existing high-current connector structure, as shown in the Chinese invention patent with the authorization number "CN205846360U" and the name "a high-current connector with low shielding resistance", includes mating plugs and sockets. The plug includes a plug housing and a pin terminal arranged in the plug housing, the socket includes a socket housing and a jack terminal arranged in the socket housing, after the plug is plugged into the socket, the The pin terminal and the jack terminal are mated to realize the conduction of the current. The disadvantages are: 1. The jack terminal is connected to the pin termin...

AI Technical Summary

Problems solved by technology

The disadvantages are: 1. The jack terminal is connected to the pin terminal through the structure of the wire spring or crown spring in the jack. The connection is unstable, the current carrying capacity is low, and the temperature rises; For cables with large outer diameters, the terminals are still crimped, and the internal resistance is high, resulting in temperature rise; 3. There is no live operation protection during disassembly, and employees are in danger of electric shock; 4. The volume is large and the design is not compact, which cannot meet the lightweight requirements
