Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 5 The utility model provides a technical solution: a high-voltage power equipment test connection device, comprising an insulating connection plate 1, a clamping assembly 2 is provided at both ends of the insulating connection plate 1, a fixing assembly 3 is provided on the side surface of the clamping assembly 2, a protective assembly 4 is provided inside the clamping assembly 2, and an observation assembly 5 is provided on the side surface of the insulating connection plate 1;

[0022] The clamping assembly 2 includes an insulating tube 201, and the opposite ends of the two insulating tubes 201 are fixedly connected to the two ends of the insulating connecting plate 1 respectively. The opposite ends of the two insulating tubes 201 are fixedly connected to extension pieces 202, and multiple extension pieces 202 are distributed in a circular array along the circular edge of the insulating tube 201. The other end of the extension piece 202 is fixedly connected to a rocker plate 203, and the side of the extension piece 202 close to the center of the circle is fixedly connected to a clamping claw 204.

[0023] In this embodiment, Figure 2 、 Figure 3 and Figure 4 As shown, the fixing component 3 includes a thread groove 303, which is opened on the side surface of the insulating tube 201. The side surface of the insulating tube 201 is threadedly connected to an internal threaded swivel 301 through the thread groove 303, and the two opposite sides of the internal threaded swivels 301 are respectively fixedly connected to a retracting sleeve 302.

[0024] In this embodiment, Figure 2 、 Figure 3 and Figure 4As shown, the protective component 4 includes a retaining ring 401, which is fixedly sleeved on the inner edge of the opposite end of the two insulating tubes 201, and a metal block 402 is fixedly sleeved on the inner wall of the insulating tube 201.

The self-locking of the internal threaded swivel 301 is achieved by rotating the threaded connection of the internal threaded swivel 301, so that the structure is stable and not easy to loosen. The force toward the center of the circle provided by the retraction sleeve 302 causes the multiple extension pieces 202 to overcome the elastic deformation and retract toward a circle, and the cables are clamped and fixed by the clamping claws 204, so that the electrical connection efficiency is improved while optimizing the operability, improving the stability and firmness.

[0025] In this embodiment, Figure 2 、 Figure 3 and Figure 4 As shown, the observation component 5 includes a retaining ring 504, which is fixedly sleeved on the side surface of one of the insulating tubes 201, and a clamping ring 501 is fixedly sleeved on the outer edge of one end of the other insulating tube 201. A clamping groove 502 is provided on the side of the clamping ring 501 close to the retaining ring 504, and a transparent tube 503 is movably sleeved on the side surface of the insulating tube 201. When in use, the cables at the power equipment end and the cables at the power supply end are stripped of the insulation layer and inserted into the two insulating tubes 201 respectively, so that the wire core and the metal block 402 are electrically connected, and then the internal threaded swivel 301 is rotated so that the internal threaded swivel 301 drives the retracting sleeve 302 to move away from the transparent tube 503. As the retracting sleeve 302 moves, the unfolded extension piece 202 and the rocker 203 are restricted by the inner wall of the retracting sleeve 302. The clamps 204 are retracted inwardly so that the multiple clamps 204 clamp the cable, and then the two ends of the fuse 404 are jointly hung on the two hooks 403 to form a complete circuit. Then, the transparent tube 503 is slid so that one end of the transparent tube 503 is clamped in the clamping groove 502, and the gap formed by the insulating connecting plate 1 is closed for protection. The fuse 404 is used as a protective structure for the circuit. When the circuit load is large during the test, it is fused, thereby protecting the safety of equipment and personnel.

The status of the fuse 404 can be directly observed through the transparent tube 503, and the blowing status of the fuse 404 can be intuitively understood, so that it can play a protective role, improve replacement efficiency, and provide an intuitive effect.

[0026] In this embodiment, Figure 2 、 Figure 3 and Figure 4 As shown, one end of the transparent tube 503 abuts against the retaining ring 504 , and the other end of the transparent tube 503 engages with the slot 502 by sliding. In this state, the transparent tube 503 is sleeved on the side surface of the insulating connecting plate 1 .

[0029] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, during use, the cables at the power equipment end and the power supply end are stripped of their insulation layers and then inserted into the two insulating tubes 201 respectively, so that the wire core is in contact with the metal block 402 and electrically connected. Then, the internal threaded swivel 301 is rotated so that the internal threaded swivel 301 drives the retracting sleeve 302 to move away from the transparent tube 503. As the retracting sleeve 302 moves, the unfolded extension piece 202 and the rocker 203 are retracted inward under the restriction of the inner wall of the retracting sleeve 302, so that multiple claws 204 clamp the cables. Then, the two ends of the fuse 404 are jointly hung on the two hooks 403 to form a complete circuit. Then, the transparent tube 503 is slid so that one end of the transparent tube 503 is clamped in the card slot 502, and the gap formed by the insulating connecting plate 1 is closed and protected.
