[0026] Please refer to with emphasis Figure 1 and Figure 3, an embodiment of the present utility model provides a loosening-preventing type automotive wiring harness terminal, including a wiring housing 1. Two first positioning mechanisms 3 for fixing a male wiring head are arranged on the outer side of the wiring housing 1. The first positioning mechanism 3 includes a support rod 35 fixed on one side surface of the wiring housing 1. One end of the support rod 35 far away from the wiring housing 1 is hinged with a limiting rod 36. Two transmission mechanisms 4 for driving the first positioning mechanism 3 are respectively arranged on the inner side wall of the wiring housing 1.

[0027] Please refer specifically to Figure 3 , the first positioning mechanism 3 includes two moving grooves 31 opened on one side surface of the wiring housing 1 and a transmission rod 34 fixedly sleeved at the bottom end of the limiting rod 36. A transmission plate 32 is slidably connected inside each moving groove 31. An inclined sliding groove 33 is opened on one side surface of each transmission plate 32. The distance between the bottom end of the inclined sliding groove 33 and the moving groove 31 is less than the distance between the top end of the inclined sliding groove 33 and the moving groove 31. Both ends of the transmission rod 34 are respectively slidably connected inside the two inclined sliding grooves 33.

[0028] In the above solution, when the moving plate 42 slides, through the cooperation between the transmission plate 32, the inclined sliding groove 33 and the transmission rod 34, the limiting rod 36 can be rotated around the support rod 35, and the two side surfaces of the connecting plate 6 can be fixed by the limiting rod 36.

[0029] The transmission mechanism 4 includes a positioning frame 41 fixed on the inner side wall of the wiring housing 1. A moving plate 42 is slidably connected inside the positioning frame 41. One side surface of the moving plate 42 close to the moving groove 31 is fixed on one side surface of the transmission plate 32. A heart-shaped groove 43 is opened on one side surface of the moving plate 42 far away from the moving groove 31. A moving frame 48 slidably arranged on the top of the positioning frame 41 is fixed on the top surface of the moving plate 42.

[0030] The transmission mechanism 4 further includes a limiting shaft 45 fixed at the bottom end of the positioning frame 41. A positioning rod 46 is rotatably connected to the periphery of the limiting shaft 45. A moving shaft 47 slidably arranged inside the heart-shaped groove 43 is fixedly sleeved at one end of the positioning rod 46 far away from the limiting shaft 45. A compression spring 44 is fixed between the inner bottom wall of the positioning frame 41 and the moving plate 42.

[0031] In the above solution, by applying an external force to insert the second wiring head 7 into the first wiring head 2, the moving frame 48 is triggered by the connecting plate 6. The moving plate 42 slides inside the positioning frame 41 through the moving frame 48, and the moving shaft 47 slides inside the heart-shaped groove 43 through the positioning rod 46. When the moving shaft 47 slides to the top end of the heart-shaped groove 43, the compression spring 44 provides elastic support for the moving plate 42 and fixes the position of the moving plate 42.

[0032] Please refer specifically to Figure 1 and Figure 4, on the outer side of the wiring housing 1, there are two second positioning mechanisms 5 for positioning the male connection heads. The second positioning mechanism 5 includes a limiting groove 51 opened on one side surface of the wiring housing 1. Inside the limiting groove 51, there is an arc-shaped plate 53 installed, and a clamping block 54 is fixed at the bottom end of the arc-shaped plate 53.

[0033] Please refer specifically to Figure 4 , the second positioning mechanism 5 includes a positioning shaft 52 fixed inside the limiting groove 51. The outer periphery of the positioning shaft 52 is rotatably sleeved inside the arc-shaped plate 53. A connecting block 55 is fixed at the top end of the arc-shaped plate 53, and a spring 56 is fixed between the connecting block 55 and the wiring housing 1.

[0034] In the above solution, the arc-shaped plate 53 is triggered by the connecting plate 6 driving the positioning plate 8. The spring 56 provides elastic support for the arc-shaped plate 53, so that the clamping block 54 is embedded into the inside of the card slot 9 to fix the two side surfaces of the connecting plate 6 again. When it is necessary to separate the wiring terminals, by pressing the top end of the arc-shaped plate 53 with an external force, the arc-shaped plate 53 rotates around the positioning shaft 52, and the clamping block 54 is moved away from the card slot 9. At the same time, after pressing the connecting plate 6 downward, the second connection head 7 is pulled out.

[0035] Please refer specifically to Figure 1 、 Figure 2 and Figure 4 , a first connection head 2 is fixed inside the wiring housing 1. A second connection head 7 is installed inside the first connection head 2. A connecting plate 6 is fixed on the top surface of the second connection head 7. Two positioning plates 8 are fixed on the bottom surface of the connecting plate 6. A card slot 9 is opened on the side surface of each positioning plate 8 away from the second connection head 7.

[0036] Working principle: When the wiring terminal is in use, the second connection head 7 is inserted into the first connection head 2 by an external force. By the connecting plate 6 triggering the moving frame 48, the moving plate 42 can slide inside the positioning frame 41, and the moving shaft 47 slides inside the heart-shaped groove 43 through the positioning rod 46. When the moving shaft 47 slides to the top end of the heart-shaped groove 43, the compression spring 44 provides elastic support for the moving plate 42 and fixes the position of the moving plate 42. When the moving plate 42 slides, through the cooperation between the transmission plate 32, the inclined chute 33 and the transmission rod 34, the limiting rod 36 can rotate around the support rod 35, and the two side surfaces of the connecting plate 6 are fixed by the limiting rod 36;

[0037] Meanwhile, the connecting plate 6 drives the positioning plate 8 to trigger the arc plate 53, and the spring 56 provides elastic support for the arc plate 53, so that the clamping block 54 is embedded into the inner part of the clamping groove 9 to fix the two side surfaces of the connecting plate 6 again. When it is necessary to separate the terminal, the top end of the arc plate 53 is pressed by an external force, so that the arc plate 53 rotates around the positioning shaft 52, and the clamping block 54 is separated from the clamping groove 9. At the same time, the connecting plate 6 is pressed downward and then the second terminal 7 is pulled out, avoiding the looseness of the terminal due to the bump of the vehicle and improving the connection stability of the terminal.
