Description

Technical Field

[0001] This application relates to the field of power equipment technology, and more specifically, to a wiring insulation sleeve for power equipment. Background Technology

[0002] As a key piece of equipment in the power system, the power transformer undertakes important functions of voltage transformation, power distribution, and transmission. Its leads and connections are exposed to the external environment and are easily corroded by contaminants such as dust, moisture, and oil, which can lead to a decline in insulation performance and potentially cause safety hazards such as leakage and short circuits.

[0003] A search revealed that Chinese patent CN203423019U discloses an insulating sleeve for electrical equipment wiring. This device solves the insulation problem at the wiring port of electrical equipment by covering it, which can prevent short circuit accidents caused by small animals or foreign objects, prevent electric shock accidents caused by pedestrians accidentally touching it, prevent electricity theft by criminals, and prevent condensation flashover and pollution flashover.

[0004] The aforementioned device requires the use of silicone rubber fasteners for fixation during use. However, these fasteners are small and prone to loss, posing a safety hazard. Furthermore, this fixing method is not conducive to sealing the insulating sleeve. Therefore, we propose an insulating sleeve for electrical equipment wiring. Utility Model Content

[0024] The technical solution of this application will now be clearly and completely described in conjunction with the accompanying drawings.

[0025] Please see Figure 1 This application provides a wiring insulation sleeve for power equipment, including a cover-shaped sleeve 1 and a cylindrical sleeve 2. The cover-shaped sleeve 1 and the cylindrical sleeve 2 are connected and fixed. The bottom of the cylindrical sleeve 2 is provided with a first opening 201, and one side of the cover-shaped sleeve 1 is provided with a second opening 101. The second opening 101 communicates with the first opening 201. A sealing plate 3 is slidably inserted into the bottom of the cylindrical sleeve 2. A sealing plate 4 is fixedly connected to the bottom of the sealing plate 3. The sealing plate 4 is inserted and engaged with the second opening 101. A baffle 5 is inserted into the end of the cover-shaped sleeve 1. A wire-clamping hole 501 is opened in the middle of the baffle 5. The wire-clamping hole 501 penetrates the baffle 5 downward.

[0026] The wire is inserted into the wire clamping hole 501, and placed inside the cylindrical sleeve 2 through the first opening 201 and the second opening 101. Then, the cover-shaped sleeve 1 is placed over the outside of the terminal block. Finally, the first opening 201 is sealed with the sealing plate 3, the second opening 101 is sealed with the sealing plate 4, and the cylindrical sleeve 2 is sealed with the baffle 5, thereby achieving the protection function of the wiring of the power equipment.

[0027] like Figure 2 and Figure 4 As shown, the cylindrical sleeve 2 has two sets of baffles 202 inside. The baffles 202 are made of elastic material, preferably elastic rubber. The two sets of baffles 202 are fixedly installed on the inner walls of both sides of the sleeve 1. The baffles 202 are divided into a vertical part 2021 and a horizontal part 2022, with the horizontal part 2022 inclined towards one side of the sleeve 1. The wire placed inside the cylindrical sleeve 2 can be bent under the action of the vertical part 2021 and can be placed on the horizontal part 2022. When the wire is pulled, both the vertical part 2021 and the horizontal part 2022 can undergo elastic deformation to balance the tension inside the wire and prevent damage to the wire connection.

[0028] like Figure 3As shown, the second opening 101 is provided with multiple sealing strips 102, which are connected and fixed to the cover-shaped sleeve 1. The sealing plate 4 has multiple sealing grooves 401 on both sides, which are dovetail-shaped. The sealing strips 102 are inserted into the sealing grooves 401. When the sealing plate 4 is inserted into the second opening 101, the sealing grooves 401 can pull the two ends of the second opening 101 of the cover-shaped sleeve 1 through the sealing strips 102, sealing the second opening 101 while simultaneously fixing the cover-shaped sleeve 1 to the outside of the terminal block.

[0029] like Figure 4 As shown, slide rails 203 are fixedly connected to both sides of the cylindrical sleeve 2. The sealing plate 3 is groove-shaped and slidably connected to the slide rails 203. A first slot 204 is provided at the end of the cylindrical sleeve 2, and a second slot 301 is provided inside the sealing plate 3. The baffle 5 is inserted into both the first slot 204 and the second slot 301. The baffle 5 can seal the cylindrical sleeve 2 by inserting into the first slot 204; and limit the sealing plate 3 by inserting into the second slot 301 to prevent the sealing plate 3 from loosening and affecting the sealing performance of the device.
