Automotive wiring harness plug-in with terminal detachment prevention function

Abstract

The invention discloses an automobile wire harness plug-in having a terminal anticreep function. The automobile wire harness plug-in having the terminal anticreep function comprises a plug-in main body, a first elastic sheet and a terminal; a plurality of terminal installation holes are arranged on the plug-in main body; an elastic sheet mechanism is arranged in the terminal installation hole; a clamping boss is arranged on the top of the elastic sheet mechanism; a semicircular hook portion is arranged on the bottom of the elastic sheet mechanism; terminals are installed inside the terminal installation holes and the bottom of the terminal has a limiting hole; installation grooves are installed on two sides of the plug-in main body; rotation locking devices are installed inside the installation grooves; a through hole is formed on the plug-in main body; a shaft is inserted in the through hole; regulation grooves are arranged on the rotation locking devices; the ends of the shaft are in sliding connection with the regulation grooves; the through hole has an upper stop point and a lower stop point; the rotation locking devices the drive yhr shaft to move between the upper stop point and the lower stop point through the installation grooves; and the first elastic sheet is fixedly arranged on the bottom of the plug-in main body along a length direction of the terminal installation hole. The automobile wire harness plug-in having the terminal anticreep function can effectively fix the terminal, prevents creeping and provides convenience to installation and dismounting.

Description

technical field [0001] The invention relates to a plug-in, in particular to an automobile wire harness plug-in with a terminal detachment prevention function. Background technique [0002] The automotive wiring harness plug-in is a transitional structure for current transmission, and the plug-in structure design and fixing reliability are crucial to the safety of the wiring harness. [0003] The wiring harness plug-in is assembled in the production line, and the reliable fixing of the plug-in is conducive to the normal implementation of the function of the wiring harness plug-in, otherwise it will easily lead to various faults such as poor contact. There are terminals in the car plug-in, which is a basic component of electrical design. After the plug-in is connected to the plug-in, the current is transmitted through the terminals in the plug-in. Reliable fixing of the terminals in the car plug-in is very important.

[0004] figure 1 It is a schematic diagram of one of the commonly used wiring harness plug-in structures in the prior art. After the two plug-ins are plugged together, they are clamped and fixed by the shrapnel 100, but the shrapnel 100 has no limit in the up and down direction, which is easy to cause loosening and cause the two plug-ins to separate.

In addition, in the prior art, the two inserts may also be separated under the action of a large external force

[0005] figure 2 It is a schematic diagram of the clamping structure between a wire harness plug-in and a terminal in the prior art. The wire harness plug-in body 200 cooperates with the hole on the terminal 400 to clamp and limit the terminal 400. This simple limit The reliability of the fixing method is low, and the terminal 400 is easy to fall off

Moreover, this clamping structure is not conducive to the disassembly of the terminal 400. To disassemble the terminal 400, tools such as pick pins are required, which is cumbersome and difficult to operate.
