The insulating protective sleeve of the power equipment is formed by high-temperature molding of silicone rubber material, with excellent electrical performance, aging resistance, high and low temperature resistance, and can be used under any conditions. In order to improve the protection of the insulating layer, a protective sleeve is needed to protect the insulating layer to prevent the insulating layer from being worn and damaged.

[0003] The existing electrical wiring insulation protection device is generally an insulating terminal with an insulating rubber sleeve. This kind of terminal generally lacks insulation protection for the pressing nut during use, so that accidental electric shock may occur when disassembling the electrical wiring. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide an electrical wiring insulation protection device to solve the technical problem that there is a lack of insulation protection for the pressing nut, so that accidental electric shock may occur when disassembling the electrical wiring.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an electrical wiring insulation protection device, including a metal sleeve, a card for wiring is arranged on one side of the metal sleeve, an insulating plastic sheet is fixedly connected to one side of the metal sleeve, and an insulating plastic sheet is fixedly connected to one side of the insulating plastic sheet. A track ring is fixedly connected, and an insulating plastic block is rotatably connected inside the track ring. A hexagonal groove is opened inside the insulating plastic block, and an insertion slot for placing a nut is opened on one side of the insulating plastic block.

[0006] By adopting the above technical scheme, the metal sleeve provides basic protection and support for the electrical wiring. The card for wiring arranged on one side of it facilitates the fixation with nuts and studs, completing the wiring operation. The fixed connection of the insulating plastic sheet provides an installation site for the track ring, improving the stability of the device.

[0007] Further, triangular blocks are fixedly connected to the outer wall of the insulating plastic block, and the triangular blocks are arranged at equal intervals in a ring shape.

[0008] By adopting the above technical scheme, the triangular blocks fixedly connected to the outer wall of the insulating plastic block on the one hand increase the surface roughness of the insulating plastic block, providing a better anti-slip effect, so that when operating the insulating plastic block to rotate, it can be held more stably and is not easy to slip.

[0009] Furthermore, an insulating plastic paddle is fixedly connected to the top of the insulating plastic sheet, and the insulating plastic paddle and the triangular block form a ratchet fit.

[0010] By adopting the above technical solution, the insulating plastic paddle fixedly connected to the top of the insulating plastic sheet provides convenience for operation, so that the user can control whether the insulating plastic block can rotate by prying the insulating plastic paddle, thereby enhancing the reliability of the device.

[0011] Furthermore, the space formed by the hexagonal groove is used to accommodate the compressed nuts and studs.

[0012] By adopting the above technical solution, the hexagonal groove provides a stable accommodation space for the nut and the stud, ensuring that they can be firmly clamped inside the insulating plastic block during the tightening process.

[0013] Furthermore, an insulating rubber sleeve is fixedly connected to the other side of the insulating plastic sheet, and one end of the insulating rubber sleeve is provided with a pressing groove for pressing the heat shrink tube.

[0014] By adopting the above technical solution, the insulating rubber sleeve fixedly connected to the other side of the insulating plastic sheet provides an additional insulating protection layer for the electrical wiring, further enhancing the safety of the device.

[0015] Furthermore, a heat shrink tube is tightly pressed inside the pressing groove.

[0016] By adopting the above technical solution, the compression groove provides a stable compression space for the heat shrink tube, ensuring that the heat shrink tube can be firmly compressed in the insulating rubber sleeve and will not be easily loosened or fallen off due to external force.

[0017] In summary, the utility model mainly has the following beneficial effects:

[0018] 1. The utility model provides a track ring, an insulating plastic block and a hexagonal groove. The insulating plastic block can be deformed and clamp the nut, ensuring that the electrical wiring is stable and safe during the fixing process. The cooperation of the insulating plastic paddle and the triangular block effectively prevents the nut from loosening after long-term use, further improving the stability and reliability of the wiring. When the device needs to be removed, the nut can be easily loosened by pulling open the insulating plastic paddle and rotating the insulating plastic block in the opposite direction, which simplifies the disassembly process and greatly reduces the risk of accidental electric shock when loosening the nut, providing higher safety protection for the operator;

[0019] 2. The utility model provides good insulation protection for electrical wiring by setting a heat shrinkable tube, placing the heat shrinkable tube inside the pressing groove, and pressing it tightly by using the elasticity of rubber to ensure that the heat shrinkable tube can be closely attached to the wiring position. The wire is inserted into the metal sleeve, and a pressing pliers is used to deform the metal sleeve so that it is closely combined with the wire to form a joint, enhancing the stability and firmness of the wiring and making the wiring process more simple and fast. By heating the heat shrinkable tube, it shrinks and closely adheres to the wiring position, further completing the sealing of the wiring position, effectively preventing the leakage of external dust, water, etc., and improving the reliability and service life of the wiring.

[0028] Next, according to the overall structure of the present utility model, its embodiments will be described.

[0029] In this embodiment:

[0030] An electrical wiring insulation protection device, as Figures 1 - 4 shown, includes a metal housing 1. One side of the metal housing 1 is provided with a card for wiring. One side of the metal housing 1 is fixedly connected with an insulating plastic sheet 2. One side of the insulating plastic sheet 2 is fixedly connected with a track ring 3. The inside of the track ring 3 is rotatably connected with an insulating plastic block 4. A hexagonal groove 5 is opened inside the insulating plastic block 4;

[0031] Among them, an insertion slot 6 for placing a nut is opened on one side of the insulating plastic block 4. The rotational connection between the track ring 3 and the insulating plastic block 4 enables the insulating plastic block 4 to rotate when needed, facilitating the tightening and loosening of the nut. The hexagonal groove 5 opened inside the insulating plastic block 4 matches the shape of the nut, ensuring that the nut 9 can be firmly clamped therein, facilitating driving the rotation of the nut 9. The insertion slot 6 for placing a nut opened on one side of the insulating plastic block 4 makes it more convenient and quick to insert and remove the nut 9.

[0032] Refer to Figure 1 、 Figure 2 and Figure 4 , a triangular block 7 is fixedly connected to the outer wall of the insulating plastic block 4, and the triangular blocks 7 are arranged at equal intervals in a ring shape;

[0033] Among them, it not only ensures the overall uniformity of the outer wall of the insulating plastic block 4 but also forms a cooperation with the subsequent insulating plastic paddle 8 to achieve the effect of relaxation.

[0034] Refer to Figure 1 、 Figure 2 and Figure 4 , an insulating plastic paddle 8 is fixedly connected to the top of the insulating plastic sheet 2, and the insulating plastic paddle 8 and the triangular block 7 form a ratchet cooperation;

[0035] Among them, the ratchet formed by the insulating plastic piece 8 and the triangular block 7 ensures that the insulating plastic block 4 can remain stable after rotating to a predetermined position and will not be easily loosened or rotated back due to external factors, further improving the stability and reliability of wiring.

[0036] Refer to Figure 1 , the space formed by the hexagonal groove 5 is used to accommodate the compressed nut 9 and stud 10, so that the nut 9 and the stud 10 can form a tight contact with the card after being compressed, enhancing the electrical performance of the electrical wiring. Since the shape of the hexagonal groove 5 matches that of the nut 9, better torque transmission can be provided during the tightening process, making the tightening operation easier and faster. In summary, this not only improves the convenience of use of the electrical wiring insulation protection device, but also further enhances its protection effect and reliability.

[0037] The implementation principle of the present utility model is as follows: First, the card is inserted under the nut 9 for fixing. At the same time, after the nut 9 expands the deformable insulating plastic block 4 from the insertion groove 6, it is inserted into the hexagonal groove 5 inside the insulating plastic block 4, so that the hexagonal groove 5 can be clamped with the nut 9. Then, the insulating plastic block 4 is rotated, and the insulating plastic block 4 drives the nut 9 to compress the card, completing the fixation of the electrical wiring. At this time, the insulating plastic piece 8 and the triangular block 7 form an anti-loosening cooperation to prevent the nut 9 from loosening after long-term use;

[0038] When the device needs to be removed, pull the insulating plastic piece 8, and then rotate the insulating plastic block 4 in the reverse direction so that the nut 9 can be loosened to prevent accidental electric shock when loosening the nut.

[0039] Refer to Figure 3 , on the other side of the insulating plastic sheet 2, an insulating rubber sleeve 11 is fixedly connected. One end of the insulating rubber sleeve 11 is provided with a pressing groove 12 for pressing the heat shrinkable tube 13. The pressing groove 12 provided at one end of the insulating rubber sleeve 11 enables the heat shrinkable tube 13 to be firmly stuck in the insulating rubber sleeve 11, providing a tight sealing layer for the electrical wiring, effectively preventing external dust, water, etc. from leaking into the wiring position, and improving the reliability and service life of the wiring.

[0040] Refer to Figure 3 , the heat shrinkable tube 13 is pressed inside the pressing groove 12, so that the heat shrinkable tube 13 can form a tight contact with the insulating rubber sleeve 11 after being pressed, providing a reliable sealing layer for the electrical wiring, effectively preventing external dust, water, etc. from leaking into the wiring position, and further improving the reliability and service life of the wiring. Since the heat shrinkable tube 13 has excellent insulation performance and high temperature resistance, this also enhances the overall insulation effect and high temperature resistance of the electrical wiring insulation protection device, enabling the device to work stably in a more severe environment.

[0041] The implementation principle of the present utility model is as follows: First, by opening a pressing groove 12 on one side of the insulating rubber sleeve 11 and placing the heat-shrinkable tube 13 inside the pressing groove 12, the heat-shrinkable tube 13 can be pressed tightly by the rubber. Then, the wire is inserted into the metal sleeve 1, and then the metal sleeve 1 is pressed and deformed by a wire pressing pliers so that it can be combined with the wire to form a joint. Finally, the heat-shrinkable tube 13 is heated to complete the sealing of the wiring position and prevent external dust, water, etc. from leaking.

[0042] Parts not involved in the present utility model are the same as or can be implemented by using the prior art, and will not be elaborated here too much.
