Problems solved by technology

[0003] The traditional curved outlet electrical connector plug generally adds an elbow at the end of the plug to achieve the purpose of the curved outlet. The elbow and the plug shell are connected by threads or buckles. , only suitable for small current plugs, because high current plugs need to use cables with larger cross-sectional areas, and cables with large cross-sectional areas have a larger turning radius, and the solution of adding a bend at the end of the plug cannot meet the requirements; the traditional For a plug with a large current curved outlet, generally a terminal and a wire connector are used first, and then the terminal is connected to the contact to achieve a curved outlet. Type outlet, but after the shell is made into a component, the protection level is difficult to meet the standard; the traditional angled connector plug with shielding function usually uses a pair of separate contacts to realize the conduction between the shields. This method of shielding treatment The shielding effect of the method is not good, and because of the extra shielded conductive contact pairs, the size of the connector is increased. It can be seen that the traditional bent outlet plug with shielding function cannot meet the requirements of modern industrial electrical systems, especially Requirements for the use of curved shielded plugs for new energy vehicles

Abstract

The invention discloses a curved high-voltage shielding plug, which relates to the field of electrical connectors in the electrical fields of new energy vehicles, industrial equipment, urban rail and railway vehicles. It includes housing assembly, contact and mounting plate assembly, tail attachment. The shell assembly is composed of a locking handle, a lock block, a plug shell, a sealing ring, and a signal pin. The locking and unlocking of the connector is realized by using the mechanism that converts the rotary motion of the handle into the linear motion of the plug shell relative to the socket shell, and can normally use the electrical connector in the case of a relatively narrow operating space, which solves the problem of traditional electrical connection The locking method of the connector cannot be used normally in a narrow operating space. At the same time, the handle also has a power-assisted effect, which improves the ease of operation of the connector.

Description

technical field [0001] The invention relates to the field of electrical connectors in the electrical fields of new energy vehicles, industrial equipment, urban rail and railway vehicles, in particular to curved high-voltage shielding plugs used in new energy vehicles. Background technique [0002] In modern industrial electrical systems, the use of electrical connectors is becoming wider and wider, and the number is increasing. There are also more and more requirements for the outlet methods of the connectors, and the demand for 90-degree bent outlets is the majority. [0003] The traditional curved outlet electrical connector plug generally adds an elbow at the end of the plug to achieve the purpose of the curved outlet. The elbow and the plug shell are connected by threads or buckles. , only suitable for small current plugs, because high current plugs need to use cables with larger cross-sectional areas, and cables with large cross-sectional areas have a larger turning rad...
