A through hole is provided in the middle of the first clamping ring 103 to facilitate the passage of the cable. The first clamping ring 103 is located Between the first tightening head 102 and the first protective shell 101, as the first tightening head 102 is tightened, the cone of the first clamping ring 103 gradually extends into the first protective shell 101, so that the first clamping ring 103 is compressed and contracted, thereby clamping the cable. The connecting nut 105 is located at the end of the first protective shell 101 and is used to connect the first protective shell 101 and the second protective shell 104 together. The second protective shell 104 is the same as the first protective shell 101. The second tightening head 106 is the same as the first tightening head 102. The second tightening head 106 is threadedly connected to the tail end of the second protective shell 104. The second The clamping ring 107 is the same as the first clamping ring 103. As the second clamping head 106 is tightened, the tapered portion of the second clamping ring 107 gradually extends into the second protective shell 104, causing the second clamping ring 107 to be compressed and contracted, thereby clamping the cable.

[0032] The second embodiment of this application is:

[0033] See also Figure 3 , Figure 3 20 is a schematic diagram of the overall structure of the protective structure of the connector of the second embodiment of the present invention. Based on the first embodiment, the protective structure of the connector of this embodiment further includes a first insulating layer 201 and a second insulating layer 202 .

The first insulating layer 201 and the second insulating layer 202 provide protection. The insulating layer materials are:

[0036] Plastic insulation:

[0037] Polyvinyl chloride (PVC): PVC is a thermoplastic resin formed by the polymerization of vinyl chloride with an initiator. PVC has excellent dielectric and mechanical properties, making it widely used in cable insulation. However, PVC is sensitive to light and heat, and prolonged exposure to high temperatures or sunlight may degrade its properties.

[0038] Cross-linked polyethylene (XLPE): XLPE is a material produced through a cross-linking reaction based on polyethylene (PE). This cross-linking reaction transforms the PE molecule from a two-dimensional structure into a three-dimensional network, significantly improving the material's chemical and physical properties, temperature resistance, and pressure resistance. XLPE is suitable for the production of high-voltage, large-section, and long-length cables.

[0039] Rubber insulation: In addition to plastic insulation, rubber is also used as insulation material for cables, especially for some applications that require higher elasticity and oil resistance.

[0040] Insulation layer principle:

[0041] The insulation layer of a cable connector wraps around the conductor, forming a barrier that prevents current from leaking into the external environment. The material and structure of the insulation layer determine its electrical, mechanical, and thermal properties. The thickness and uniformity of the insulation layer are also critical factors. Too thin an insulation layer can lead to electrical breakdown, while an uneven insulation layer can cause uneven electric field distribution, leading to partial discharge or breakdown.

[0042] In order to ensure the insulation performance of cable joints, additional measures are usually taken, such as using insulating sleeves and insulating tape to enhance the protection and sealing performance of the insulation layer. In addition, the manufacturing process and quality control of cable joints are also key links to ensure insulation performance.

[0043] In this embodiment, by providing the first insulating layer 201 and the second insulating layer 202 , safety is further improved, thereby playing a protective role.

A person skilled in the art will understand that all or part of the processes of the above embodiments and equivalent changes made in accordance with the claims of the present application are still within the scope of the present application.
