Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple strands of wires and an insulating layer, used to connect circuits, electrical appliances, etc. Cables can be divided into DC cables and AC cables according to the system of photovoltaic power stations, and can be divided into DC cables and AC cables according to different uses and use environments. Cable connectors are devices for connecting cables. In the construction of power cable laying, the length of bypass cables required at different sites is different. Cable connectors are usually used to connect segmented bypass cables to quickly extend or shorten the length of bypass cables.

However, with this connection method, the contact area between the copper cores of the two cables is small, resulting in poor contact or heat generation at the connection points of the connected cables during use, which is inconvenient to use. At the same time, the connector assembly of the existing cable connector has poor sealing performance, and water can easily penetrate into the connector, causing leakage at the cable connection.
