[0021] The following will be combined with the Figure 1 -Appendix Figure 6 Further detailed description of the present application:

[0022] The present application discloses a kind of harness plug to prevent poor contact, such as Figure 1 、 Figure 2 、 Figure 3As shown, the utility model discloses a wire harness plug of preventing bad contact, including male joint 1 and female joint 2, be provided with the anti-loosening assembly for making male joint 1 and female joint 2 lock tightly between male joint 1 and female joint 2, male joint 1 includes the slot 11, connecting sleeve 12, the slot 11 is integrally formed with connecting sleeve 12, the inside of slot 11 is provided with the contact pin 13, female joint 2 includes the plug 21, base 22, plug 21 and base 22 are integrally formed, the plug 21 is provided with the insertion hole 23 that cooperates with contact pin 13, and contact pin 13 is inserted to the inside of insertion hole 23 and is electrically connected, in the embodiment, the specific structure of slot 11, connecting sleeve 12 is as shown in Figure 3 As shown, when the plug 21 of female joint 2 enters the slot 11 of male joint 1, the contact pin 13 in the slot 11 will enter the insertion hole 23 on the plug 21, and the advantage of this design is that the internal contact pin 13 can be protected by the slot 11 to prevent the contact pin 13 from being bent. By setting the anti-loosening assembly, the male joint 1 and the female joint 2 can be firmly locked after being inserted, avoiding the loosening problem caused by vibration, impact or temperature change.

[0023] As shown in Figure 4 , Figure 5 , Figure 6 As shown, the anti-loosening assembly includes a locking block 31, a spring 32, and a bolt 33. The inner wall of the connecting sleeve 12 is integrally formed with two protrusions 34. The opposite side walls of the two protrusions 34 are respectively provided with sliding grooves 35. The two protrusions 34 are slidably connected with the locking block 31 through the sliding grooves 35. The outer side wall of the connecting sleeve 12 is provided with a threaded hole. The threaded hole is threadedly connected with the bolt 33. The bolt 33 can push the locking block 31 to move towards the female joint 2. The inside of the sliding groove 35 is provided with the spring 32. The spring 32 can push the locking block 31 to move away from the female joint 2. Figure 5 As shown, one spring 32 is arranged in each of the two sliding grooves 35. The shape of the locking block 31 is as shown in Figure 5 After the plug 21 is inserted into the slot 11, the bolt 33 is screwed. The bolt 33 pushes the locking block 31 to move towards the female joint 2 and compresses the spring 32. The locking block 31 abuts against the outside of the base 22, so that the plug 21 is tightly connected with the slot 11, preventing bad contact. By setting the bolt 33, the locking and loosening operations are more convenient. The user only needs to tighten or loosen the bolt 33 to realize the fixation or disassembly of the plug 21 without the need for complex tools. Preferably, the number of anti-loosening assemblies is two. The two anti-loosening assemblies are respectively arranged on the opposite two inner walls of the connecting sleeve 12. The two anti-loosening assemblies limit the base 22 from both sides of the base 22. Preferably, the locking block 31 is made of rubber material. The locking block 31 is made of rubber material, which has good elasticity and shock absorption performance, further enhancing the stability of the plug 21 in a vibrating environment

[0024] As shown inFigure 6 As shown, the end face of the locking block 31 in contact with the female connector 2 is rounded, and in this embodiment, the cross section of the end face of the locking block 31 is semicircular. When the bolt 33 is screwed, if the plug 21 is not fully inserted into the slot 11, the end of the bolt 33 can also push the base 22, so that the plug 21 is fully inserted into the slot 11.

[0025] As shown in Figure 2 , Figure 4 , the inner side wall of the slot 11 is integrally formed with a plurality of prisms 36, and the outer side wall of the plug 21 is provided with a plurality of prism grooves 37. When the male connector 1 and the female connector 2 are connected, the prisms 36 can be embedded with the prism grooves 37. In this embodiment, through the embedded design of the prisms 36 on the inner side wall of the slot 11 and the prism grooves 37 on the outer side wall of the plug 21, the relative rotation or displacement of the male connector 1 and the female connector 2 after insertion can be effectively prevented, and the electrical connection between the pin 13 and the socket 23 can be ensured.

[0026] The implementation principle of the embodiment of the utility model is:

[0027] When connected, first insert the plug 21 into the slot 11, and then screw the bolt 33.
