Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] see figure 1 , as can be seen from the figure, the vehicle high-voltage cable self-locking plug pair of the present invention includes a socket 1 and a plug 2 that match each other. The socket and plug are described respectively below.

[0021] socket. The end face of the socket 1 has an axial jack 11, the inner wall of the jack 11 is provided with an elastic locking ring groove 12, and an elastic locking ring 13 is embedded in the elastic locking ring groove 12, and the elastic locking ring is stuck in the ring. The groove cannot move in the axial direction. The elastic locking ring 13 protrudes from the elastic locking ring ring groove 12 in a natural state, and can retreat back into the elastic locking ring ring groove under extrusion. The surface of the socket 1 is provided with an insulating sleeve 14, and the insulating sleeve 14 is provided with a mounting...

Abstract

The invention discloses a vehicle high-voltage cable self-locking splicing pair which comprises a socket and a plug, wherein an axial jack is formed in the end face of the socket; an elastic locking ring is embedded in an elastic locking ring annular groove of the inner wall of the jack; the elastic locking ring is in a sealed ring shape which is formed by spirally winding an electric conduction metal wire; a guide bevel edge which facilitates the plug to pass is formed in the direction, facing the plug, of the section of the elastic locking ring; a locking straight edge which is vertical to the axis is formed in the direction opposite to the plug; the plug is provided with an insertion pillar which is matched with the jack of the socket; the head of the insertion pillar is provided with a guide taper which facilitates the insertion pillar to insert into the jack; an unlocking sleeve is sleeved in an unlocking sleeve annular groove in the surface of the insertion pillar. The splicing pair is provided with a locking function, the locking is reliable, the unlocking is convenient, the complicated mechanical structure is omitted, the structure is simple, the use is convenient, and the cost of the splicing pair is low. The splicing pair is used for self-locking connection of a high-voltage cable of an electrocar, and the connection and the disconnection of the high-voltage cable are conveniently carried out.

Description

technical field [0001] The invention relates to a vehicle cable connection structure, in particular to a vehicle high-voltage cable self-locking plug-in pair, which belongs to the technical field of vehicle cable connections. Background technique [0002] At present, new energy vehicles, especially pure electric vehicles, are becoming a development hotspot. Many components on pure electric cars are high-voltage and high-current components. During the connection process of electrical systems and electrical components, they often need to be connected through self-locking plug-in pairs. Due to the large bumps and jitters of the car during operation, the connectors are easy to loosen and cause malfunctions. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a vehicle high-voltage cable self-locking plug-in pair that is easy to plug in, capable of reliable locking and easy unloc...
