[0027] In this embodiment, an anti-skid pad is bonded to the surface of the arc-shaped fixing plate 805, and the surface of the anti-skid pad is provided with anti-skid patterns. The number of the reset spring 804 and the arc-shaped fixing plate 805 is two groups, and they are symmetrically arranged on the inner wall of the circular retaining ring 803. The anti-skid pad is provided to increase the contact friction between the arc-shaped fixing plate 805 and the wire 9, thereby improving the fixed clamping effect.

[0028] In this embodiment, the movable component 7 includes a connecting frame 701, the inner top wall of the connecting frame 701 is provided with a sliding groove 702, the inner wall of the sliding groove 702 is fixedly connected with a connecting rod 703, the outer part of the connecting rod 703 is sleeved with a sliding block 704, the surface of the sliding block 704 is provided with a limiting opening, and the telescopic rod 801 is fixedly installed inside the limiting opening. Through the setting of the movable component 7, the use position of the wiring harness component 8 can be adjusted by horizontally moving the sliding block 704 on the connecting rod 703, so that the wiring harness component 8 can flexibly adjust the use position according to the length of the wire 9, and the applicability is stronger.

[0029] In this embodiment, the outer protection component 2 includes a protective cover 201, and a protrusion 204 is fixedly connected to the center of the back side of the protective cover 201. Through the arrangement of the outer protection component 2, the contact body 1 can be shielded and protected by the access tube 5 when it is not in use, thereby preventing external dust or liquid from entering therein.

[0030] In this embodiment, the protective cover 201 is fixedly connected to the four corners of the front side with an insertion rod 203, and the surface of the contact body 1 is provided with docking holes 3 at the four corners. By inserting the insertion rod 203 into the docking hole 3, the protective cover 201 and the contact body 1 can be movably docked, and disassembly and assembly are convenient.

[0031] Embodiment 2:

[0032] Based on the first embodiment, a preferred embodiment of the electrical contact assembly provided by the present invention is as follows: Figures 1 to 4 As shown:

[0033] In this embodiment, magnetic sheets are provided at the end of the insertion rod 203 and the inside of the docking hole 3. The sizes of the two sets of magnetic sheets match each other.

The arc-shaped fixing plate 805 clamps and fixes the wire 9 after the return spring 804 contracts and deforms. The setting of the anti-slip pad increases the contact friction between the two, thereby improving the fixing effect. After completing the above steps, the telescopic rod 801 is pulled up to lift the position of the wire 9 to avoid the wire 9 directly contacting the ground and causing friction. The use position of the wire harness assembly 8 is adjusted by the sliding block 704 on the connecting rod 703 can be adjusted by horizontal movement, which is suitable for wires 9 of different lengths. After the contact body 1 is used, the protective cover 201 is inserted into the docking hole 3 on the surface of the contact body 1 through the insertion rod 203 on its surface, and the installation of the outer protection component 2 is completed through the adsorption docking of two sets of magnetic suction plates.

[0037] In summary, with the aid of the above-mentioned technical scheme of the utility model, the wire 9 passing through the contact body 1 can be pulled up by setting the wire harness assembly 8, so as to avoid the wire 9 from being worn due to contact and friction with the ground or the table during use, thereby reducing the probability of wear of the wire 9. At the same time, the use position of the wire harness assembly 8 can be flexibly adjusted by the movable assembly 7, which is suitable for wires 9 of different lengths. The setting of the outer protection assembly 2 can connect to the access tube 5 for shielding and protection when the contact body 1 is not in use, so as to prevent external dust or liquid from entering therein. In combination with the sealing strip 202, the protective cover 201 can be inserted into the sealing groove 4 after being connected to the contact body 1, so that the two can be more closely connected, thereby further improving the dustproof and waterproof effects.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
