High-voltage and low-voltage wiring harness connector for energy storage of new energy pure electric vehicle

Abstract

The invention provides a high-voltage and low-voltage wiring harness connector for energy storage of a new energy pure electric vehicle. The connector comprises a wire positioning ring, a locking cover, a T-shaped sliding block, positioning shafts, a top clamping insert frame, positioning blocks and T-shaped sliding frames, wherein a female head is rectangularly arranged on the whole; a round cake-shaped wire holder is protruded and supported on the rear end face of the female head; the locking cover is screwed on the round cake-shaped wire holder; an inward-concave square slot is arranged inthe front end face of the female head; three power plug bushes are supported in the square slot in a triangular array; a positioning frame is arranged on the top end face of the female head through injection molding; the front end of the positioning frame is open; head ends of left and right support rods of the positioning frame are bent to the inner side to form a blocking plate; and a T-shaped sliding block is slidably arranged inside the positioning frame. Two limiting plates are arranged and two tightening frames can be respectively limited through spaces between the two limiting plates and left and right supporting plates of the positioning frame to avoid a male head rotating and falling off from the female head.

Description

technical field [0001] The invention belongs to the technical field of wire harness connectors, and more specifically relates to a new energy pure electric vehicle energy storage high and low voltage wire harness connector. Background technique [0002] A connector is a component that people often come into contact with. Its function is very simple: to build a communication bridge between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can realize the predetermined function. Connectors are an indispensable part of electronic equipment. If you follow the path of current flow, you will always find one or more connectors. The form and structure of connectors are ever-changing, and there are various forms of connectors depending on the application object, frequency, power, application environment, etc. For example, electric vehicle energy storage high and low voltage harness connectors, connectors for lighting on the field, connectors f...

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a new energy pure electric vehicle energy storage high and low voltage wire harness connector to solve the problem that the existing wire harness connector has not done too much applicability optimization for the bumpy and vibrating driving environment of the car, resulting in the connector The referendum and the female head are easy to be disconnected due to the shaking and vibration, and the cable and the terminal block will also vibrate up and down relative to each other during the bumpy driving process, which will easily cause the copper wire of the cable to fatigue and break during the shaking and connect with the wiring. In addition, due to the excessive pursuit of the butt tightening strength of the male and female connectors, a complex tightening positioning structure and multi-card setting limit are installed, which makes it inconvenient to plug and disassemble the male and female connectors.
