High-voltage connector with safety lock

Abstract

The invention provides a high-voltage connector with a safety lock, which is used for an electric automobile and a hybrid automobile. The high-voltage connector comprises an outer casing assembly, anupper casing assembly, a bottom cover assembly and a wire; the connection relationship is that: the outer casing assembly and the upper casing assembly are in plugging connection, the outer casing assembly and the bottom cover assembly are connected to each other, and the wire is inserted and connected to the outer casing assembly; the outer casing assembly comprises a casing, a pulling fastener,a locking fastener and a button; the outer casing is connected with the pulling fastener, the locking fastener, and the button; the outer casing comprises a convex portion, and the convex portion comprises two side strips, a hollow portion and a cover portion; the locking fastener comprises a lock body portion, two stopping bars, and a clamping and stopping portion and a locking and pushing portion, wherein one ends of the stopping bars are connected to lock stoppers; after assembly, the lock stoppers are located in through hole grooves, and the lock stoppers are connected to upper bumps. Theinvention is a simple and reliable secondary unlocking structure.

Description

technical field [0001] The invention relates to an automobile device, in particular to a high-voltage connector with a safety lock used in a circuit connection system of an electric vehicle and a hybrid vehicle. Background technique [0002] At the current stage of social and economic development, people are more and more aware of environmental protection, and the demand for low-carbon economy and low-carbon life is becoming stronger and stronger. At the same time, oil prices continue to rise. Therefore, for the automotive industry, people are urgent Seek new engine technologies to replace traditional internal combustion engine technologies. In this context, energy-saving and environmentally friendly electric vehicles and hybrid vehicles have attracted more and more attention and concern, and the promotion and popularization of electric vehicles and hybrid vehicles will inevitably become a trend, and the use of electric vehicles and hybrid vehicles will It will greatly prom...

AI Technical Summary

Problems solved by technology

[0004] (1) There is no secondary unlocking structure, or the secondary unlocking structure is complicated;

[0005] (2) There is no fastening structure for the tail harness, or the fastening structure is complicated;

[0006] (3) There are too few contacts between the shielding covers;

[0007] (4) Pulling the terminal fixing frame is easy to cause deformation of the shielding cover

[0008] In summary, the existing high-voltage connectors still have room for improvement
