Technical Field

[0001] This utility model relates to the field of wire harness connector technology, specifically to a waterproof automotive wire harness connector. Background Technology

[0002] A wire harness connector is a type of terminal. A connector, also known as a plug, consists of a plug and a socket. Connectors are relay stations in automotive circuits and are an indispensable part of automotive accessories. With the rapid development of the automotive manufacturing industry, the performance parameters of automobiles are gradually improving, and the demand for various automotive accessories is also constantly increasing.

[0003] However, the connection between the current automotive wiring harness connector and the automotive wiring harness is prone to detachment due to pulling, affecting the normal use of the vehicle. Therefore, a waterproof automotive wiring harness connector is proposed to overcome the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof automotive wiring harness connector. After connecting the first connector and the second connector, by rotating the U-shaped block, the limiting block is squeezed during the rotation, causing it to move upward, which in turn moves the L-shaped block and the spring. The spring generates tension, and under the action of the tension, the limiting block inserts into the limiting hole to limit the U-shaped block. The U-shaped block limits the second connecting flange, thus solving the problem that the connection is prone to falling off due to pulling, affecting the normal use of the car.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a waterproof automotive wiring harness connector, comprising a first connector and an anti-detachment mechanism. A second connector is inserted into one side of the first connector, and a first connecting flange is provided on one side of the first connector. A second connecting flange is provided on one side of the second connector, and the second connecting flange corresponds to the first connecting flange. The anti-detachment mechanism includes a frustum and a U-shaped block. Two frustums are provided, located at the upper and lower parts of one side of the first connecting flange, respectively. A stepped rod is provided at one end of the frustum. The two vertical rods of the U-shaped block are respectively engaged with the stepped rod, and the horizontal plate of the U-shaped block is fitted onto one side of the second connecting flange.

[0007] Furthermore, an installation hole is provided on the stepped rod located on the upper part of the first connecting flange. A spring is provided inside the installation hole. An L-shaped block is provided on the top of the spring. A limiting block is provided at the bottom of one end of the L-shaped block. A limiting hole is provided on the U-shaped block. The limiting block is set in the limiting hole.

[0008] Furthermore, the bottom side of the limiting block is designed with a sloping structure.

[0009] Furthermore, a protrusion is provided on one side of the first connecting flange, and a slot is provided on one side of the second connecting flange, with the protrusion inserted into the slot.

[0010] Furthermore, a sealing gasket is provided between the first connecting flange and the second connecting flange.

[0011] This utility model has the following beneficial effects:

[0012] After connecting the first connector and the second connector, this utility model rotates the U-shaped block, which in turn squeezes the limiting block and moves it upward, causing the L-shaped block and the spring to move. The spring generates tension, and under the action of the tension, the limiting block inserts into the limiting hole to limit the U-shaped block. The U-shaped block limits the second connecting flange, thus solving the problem that the connection is prone to falling off due to pulling, which affects the normal use of the car.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A second connector 2 is inserted into one side of the first connector 1. The first connector 1 and the second connector 2 serve as basic electrical connection carriers to realize conduction and signal transmission between the wiring harnesses. A first connecting flange 101 is provided on one side of the first connector 1, and a second connecting flange 201 is provided on one side of the second connector 2. The second connecting flange 201 corresponds to the first connecting flange 101, and the second connecting flange 201 and the first connecting flange 101 provide mechanical fixation. The interface and sealing pressure surface, the anti-detachment mechanism 3 includes a frustum 301 and a U-shaped block 307. There are two frustums 301, which are located on the upper and lower parts of one side of the first connecting flange 101 respectively. One end of the frustum 301 is provided with a step rod 302. The frustum 301 and the step rod 302 serve as the fixed base and motion guide rail of the anti-detachment mechanism 3. The two vertical rods of the U-shaped block 307 are respectively fitted on the step rod 302. The horizontal plate of the U-shaped block 307 is fitted on one side of the second connecting flange 201. The U-shaped block 307 is linked with the second connecting flange 201 to achieve mechanical locking.
