Description

Technical Field

[0001] This utility model relates to the field of insulation protection technology, and in particular to an electrical wiring insulation protection device. Background Technology

[0002] Electrical wiring mainly refers to the circuits designed in power plants, substations, and power systems to meet predetermined power transmission and operational requirements, indicating the interconnection relationships between high-voltage electrical equipment. During power transmission, various cables are typically used as power transmission components. Due to the limited length of cables, long-distance power transmission usually requires cable splicing. However, the current at cable splices is relatively large; therefore, to ensure safety, insulation protection mechanisms are needed at the connection points.

[0003] However, existing insulation protection devices are usually fitted onto the connection points of the wiring. After the protection is applied, it is not convenient to inspect and repair the wiring at the connection points, making them rather inconvenient to use. Utility Model Content

[0005] To achieve the above objectives, one embodiment of this utility model provides an electrical wiring insulation protection device, including an insulating fixing base fitted onto the surface of the end of an electrical cable. The insulating fixing base contains two waterproof insulating sleeves that cover the electrical cable and are mutually aligned. A sealing end cap is provided on one side of each waterproof insulating sleeve to close it. A locking block for positioning and pulling is fixedly connected to one end of each sealing end cap. A locking rod for locking and securing the sealing end cap is fixedly installed inside the locking block. Insulating gaskets are provided on both sides of the sealing end cap for sealing. An insulating sheet is provided on one side of each insulating gasket to cover the end of the sealing end cap. Anti-slip pressure blocks for tightening and pressing are fixedly installed at both ends of the insulating fixing base.

[0007] The above technical solution is adopted: the fastening pads (made of silicone rubber) at both ends of the insulating fixing seat are tightly fitted to the electrical cable through interference fit to prevent axial displacement, the central slot accommodates the sealing end cap, and the waterproof insulating sleeves on both sides elastically cover the cable joint. The outer diameter is interference fitted with the inner diameter of the sealing end cap to form an initial waterproof barrier.

Together with the waterproof insulating sleeve, the protection level is improved and moisture is prevented from entering.

[0010] Preferably, in any of the above embodiments, the locking and fixing block includes a locking plate for connection and a limiting rubber block made of elastic material. The locking plate is fixedly installed at one end of the sealing end cap, and the two ends of the locking plate are fixedly connected to the limiting rubber blocks that are locked inside the insulating fixing seat.

[0011] The above technical solution is adopted: the locking plate is fixed to the end face of the sealing end cover, and the limiting rubber blocks at both ends are inserted into the slots of the insulating fixing seat. The positioning force is generated by elastic deformation to ensure the initial stability of the sealing end cover when it is closed.
