[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1-Figure 5As shown, a loose-proof connection harness comprises a copper core wire 4, each of which is fixed with a wiring plug 5 at both ends of the copper core wire 4. The wiring plug 5 is plugged into the socket in the device housing to complete the connection of power and data transmission. A protective rubber sleeve 2 is fixed to the outside of the copper core wire 4. The length of the copper core wire 4 in the protective rubber sleeve 2 is not less than the length of the protective rubber sleeve 2. In order to facilitate the later installation of other wires, a hollow tube 3 arranged parallel to the copper core wire 4 is fixed inside the protective rubber sleeve 2. The length of the hollow tube 3 exceeds the length of the protective rubber sleeve 2. Both ends of the protective rubber sleeve 2 of the hollow tube 3 are fixed with a wire clamping terminal 1 that firmly clamps the protective rubber sleeve 2 on the outer wall of the hollow tube 3 and the copper core wire 4 through a detachable connection. The protective rubber sleeve 2 is fixed to the outer wall of the hollow tube 3 and the copper core wire 4 through the wire clamping terminal 1. When the protective rubber sleeve 2 is affected by tension, the internal copper core wire 4 is less affected and does not It is easy to break, and the end of the copper core wire 4 connected to the wiring plug 5 is not affected by the deformation of the protective rubber sleeve 2 and will not move easily. The wire terminal 1 includes a first card body 11 and a second card body 12 that are buckled together. The inner walls of the first card body 11 and the second card body 12 are formed with a clamping boss 13 that separates the hollow tube 3 and the copper core wire 4. The distance between the two clamping bosses 13 does not exceed twice the wall thickness of the protective rubber sleeve 2. After the first card body 11 and the second card body 12 are clamped together, the protective rubber sleeve 2 can be clamped to achieve a firm fixation of the wire terminal 1 and the protective rubber sleeve 2 to avoid loosening. The outer walls of the first card body 11 and the second card body 12 are both formed with a clamping groove 15 that is installed in conjunction with the device housing, and an anti-loosening ring 6 is installed in the clamping groove 15. The anti-loosening ring 6 is an elastic rubber ring with a certain elasticity, which can achieve waterproof and anti-loosening effects.

[0030] In this embodiment, at least two groups of hooks 16 are symmetrically formed on one side of the first card body 11 facing the second card body 12, and an inner slot 17 that cooperates with the hook 16 is symmetrically formed on one side of the second card body 12 facing the first card body 11. The end of the hook 16 away from the first card body 11 is wedge-shaped, and a disassembly groove 18 that penetrates into the inner slot 17 is formed on the side wall of the second card body 12 to facilitate the disassembly of the wire terminal 1, thereby realizing the recovery of the wire terminal 1 or adjusting the distance between the protective rubber sleeve 2 and the wiring plug 5.

[0031] In this embodiment, in order to further improve the firmness of the fixing between the wire clamping terminal 1 and the protective rubber sleeve 2 , a plurality of teeth 14 that are clamped into the outer wall of the protective rubber sleeve 2 are formed on the clamping boss 13 .

[0032] In this embodiment, in order to increase the friction between the clamping terminal 1 and the inner wall of the protective rubber sleeve 2 and improve the firmness of the fixation, anti-slip grooves 19 are formed on the inner walls of the first clamping body 11 and the second clamping body 12 .

[0033] In this embodiment, after the wire clamping terminal 1 is installed, the distance between its inner wall and the outer wall of the hollow tube 3 and the copper core wire 4 does not exceed the wall thickness of the protective rubber sleeve 2. The material properties of the protective rubber sleeve 2 can be used to firmly clamp the protective rubber sleeve 2 on the outer wall of the hollow tube 3 and the copper core wire 4, thereby improving the fixing effect and ensuring the sealing effect.

[0034] The working principle of the utility model is as follows: when in use, the protective rubber sleeve 2 is cut to an appropriate length as needed, and the protective rubber sleeve 2 is sleeved on the outside of the copper core wire 4 when the wiring plug 5 is fixed to the copper core wire 4, and then the two wiring plugs 5 are fixed. When installing the wiring harness, the two wiring plugs 5 are respectively plugged into the corresponding sockets, and a hollow tube 3 is passed through the protective rubber sleeve 2, and then the position of the protective rubber sleeve 2 is adjusted and the wire clamping terminal 1 is clamped at both ends of the protective rubber sleeve 2, and the clamping hook 16 is connected to the inner clamping groove. 17 can be used to fix the protective rubber sleeve 2, the copper core wire 4 and the hollow tube 3 together by using the wire clamping terminal 1. When installing the second wire clamping terminal 1, the copper core wire 4 needs to be fed into the protective rubber sleeve 2 by 3-5 mm to prevent the copper core wire 4 from being pulled. Then, the anti-loosening ring 6 is sleeved in the clamping groove 15, and the clamping groove 15 of the wire clamping terminal 1 is placed in the installation groove reserved on the device shell. When the two halves of the device shell are fixed together by bolts and buckles, the wire clamping terminal 1 can be fixed to the device shell (such as Figure 6 as shown).
