Bending high-voltage shielding plug

Abstract

The invention discloses a bending high-voltage shielding plug, and relates to the electric connector field of the electric appliance field of new-energy vehicles, industrial equipment, urban rails and railway vehicles. The bending high-voltage shielding plug comprises a shell assembly, a contact piece, an installation plate assembly and a tail accessory. The shell assembly is composed of a locking handle, a locking block, a plug shell, a seal ring and a signal pin. Locking and unlocking of a connector are achieved by adopting a mechanism which can convert handle rotation motion into rectilinear motion of the plug shell relative to a socket shell, the electric connector can be normally used on the condition that the operation space is narrow, the problem that a locking mode of a traditional electric connector cannot be normally used in the narrow operation space is solved, and meanwhile the handle has the power-assistant effect so that the operability of the connector is improved.

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...

[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
