Description

[0003] In the use process of the existing automobile wiring harness connector, the male terminal and the female terminal are commonly connected by the buckling plate clamping mode. Such a connection mode requires the buckling plate to be tightly clamped to ensure the stability of the wiring harness connection. If the buckling plate deforms, the connector will loosen, which will cause poor contact of the wiring harness, affect signal transmission and affect the use of the automobile.

[0004] For example, the utility model patent (application number: CN202222206198.1) discloses an automobile wiring harness connector, which includes a buckling plate, and the buckling plate is strengthened at the root by an anti-bending body to improve the bending resistance of the buckling plate. When the connector is pulled out, the buckling plate can be prevented from being broken or the root of the buckling plate from being plastically deformed. The specification discloses that in the connector structure of the automobile wiring harness, the male terminal and the female terminal are connected by the clamping of the buckle block on the male terminal and the buckling plate on the female terminal, which ensures the stability of the connection. However, due to the tight connection of the connector buckle, the buckling plate is lifted outward by the nail or the lever during the pulling-out process of the automobile wiring harness connector, which causes the buckling plate to separate from the buckle block. However, due to the uncertainty of the force during the operation, the buckling plate is bent too much, the root of the buckling plate connected to the connector terminal is broken or plastically deformed, loses elasticity, and the buckle structure loses its function. Therefore, the root of the buckling plate needs to be strengthened to improve its bending resistance. The above-mentioned patent can prove the defects of the existing technology.

[0005] Therefore, we improve it and propose an automobile connector. CONTENT OF THE UTILITY MODEL

[0026] Embodiment 1

[0027] With reference to Figures 1-5 For the first embodiment of the present application, an automobile connector is provided, which comprises a wire harness 3, and further comprises a male terminal 1 and a female terminal 2. The male terminal 1 comprises a first connecting seat 11, and the wire harness 3 is mounted in the first connecting seat 11. The end of the first connecting seat 11 is provided with a connecting groove 19. The two sides of the first connecting seat 11 are respectively provided with U-shaped plates 18. The two sides of the first connecting seat 11 are respectively provided with first movable grooves 12. A vertical rod 15 is linearly and slidably arranged in the first movable groove 12. The top end of the vertical rod 15 penetrates above the first connecting seat 11. An elastic member 14 is mounted in the first movable groove 12. The elastic member 14 is used to drive the vertical rod 15 to move towards the center line of the first connecting seat 11. The female terminal 2 comprises a second connecting seat 21. Two groups of connecting heads 22 are arranged in the second connecting seat 21. The upper and lower sides of the connecting head 22 are respectively provided with clamping plates 23. The clamping plate 23 is provided with a clamping groove 24. The connecting head 22 is inserted into the connecting groove 19. The clamping plate 23 is slidably connected with the upper end surface and the lower end surface of the end of the first connecting seat 11. The U-shaped plate 18 is used to be inserted into the clamping groove 24. When the insertion state is achieved, the lower end surface of the clamping groove 24 is attached to the upper end surface of the end of the first connecting seat 11.

[0028] The top end of the first movable groove 12 penetrates above the first connecting seat 11. The two sides above the first connecting seat 11 are respectively provided with ear plates 16. The ear plate 16 is attached to the outer wall of the first connecting seat 11. The top end of the vertical rod 15 is fixedly connected with the ear plate 16. The ear plate 16 is used for dustproof of the first movable groove 12.

[0029] The top and bottom of each U-shaped plate 18 are respectively connected with angle rods 17. The extension end of the angle rod 17 penetrates into the first movable groove 12, and the extension end of the angle rod 17 is connected with the vertical rod 15. A second movable groove 13 for horizontal sliding of the angle rod 17 is arranged on the first connecting seat 11. When the vertical rod 15 moves linearly, the corresponding angle rod 17 moves linearly along with the corresponding vertical rod 15. The connecting groove 19 of the end of the first connecting seat 11 is provided with two connecting grooves 19. Two connecting grooves 19 are respectively provided with adapter pieces 4. The adapter piece 4 is used to connect the end of the wire harness 3. The adapter piece 4 is electrically connected with the connecting head 22.

[0030] During use, when the male terminal 1 and the female terminal 2 need to be connected, by controlling the two lugs 16 on the top of the first connecting seat 11, the vertical rod 15 pushes the corner rods 17 on both sides to move to the sides respectively, causing the U-shaped plate 18 to move to both sides of the first connecting seat 11. Then, the connector 22 of the female terminal 2 is axially inserted into the connecting groove 19. At this time, the end of the first connecting seat 11 and the second connecting seat 21 are in the following position. Figure 4 In the plug-in state shown, the two vertical rods 15 are moved towards the centerline of the first connecting seat 11, so that the U-shaped plates 18 on both sides are inserted into the corresponding slots 24. Furthermore, under the limiting effect of the elastic element 14, the male terminal 1 and the female terminal 2 can be stably connected. Figure 2 As shown, when the U-shaped plates 18 on both sides are reset, the upper and lower ends of the U-shaped plates 18 pass through the clamping plate 23 respectively. Therefore, even when the elastic driving force of the elastic element 14 is unstable, the stable connection between the male terminal 1 and the female terminal 2 can still be guaranteed.

[0031] Example 2

[0032] Reference Figures 3-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0033] Elastic element 14 is an arc-shaped elastic plate, such as Figure 3 As shown, the elastic plate can provide a more stable elastic force than the spring, so as to push the vertical rod 15 to move towards the center line of the first connecting seat 11.

[0034] The inner end face of the top of the U-shaped plate 18 is in contact with the upper end face of the first connecting seat 11, and the inner end face of the bottom of the U-shaped plate 18 is in contact with the lower end face of the first connecting seat 11. The upper end face and the lower end face of the first connecting seat 11 are respectively provided with sliding grooves for sliding with the locking plate 23.

[0035] When the male terminal 1 and the female terminal 2 are plugged in, the U-shaped plates 18 on both sides drive the card plate 23 to be stably limited in the groove. The end of the first connecting seat 11 is inserted into the second connecting seat 21 and fits against the inner wall of the second connecting seat 21, thereby further realizing the stable plugging and mating of the male terminal 1 and the female terminal 2.

[0036] The remaining structure is the same as that in Example 1.
