Description

Technical Field

[0001] This invention relates to the field of power equipment technology, specifically to cable connection adapters. Background Technology

[0002] Cables are crucial carriers for transmitting electrical energy, electrical signals, or optical signals in power systems, communication networks, and various electronic devices. Through conductors (such as copper, aluminum, or optical fibers) wrapped in insulation layers, they enable the transfer of energy and signals between different devices, equipment, or systems. They are widely used in power transmission, communication transmission, industrial control, and other scenarios to ensure stable power supply and efficient information transmission. Cable adapters, on the other hand, are connecting components used between cables of different specifications, types, or interfaces. By adapting to different interface shapes, sizes, or signal types, they solve cable interface incompatibility problems, enabling line extension, branching, or equipment docking. At the same time, they ensure the conductivity, insulation, or signal transmission quality of the connection points, simplify the line connection process, and improve wiring flexibility and equipment adaptability.

[0003] In the current use of cable connection adapters, cables need to be fixed inside conduits during installation to ensure the safe and stable operation of the line. However, the cable size cannot be guaranteed to be completely consistent with the conduit size, causing the cable to sway inside the conduit after installation. During use, the swaying cable not only causes displacement leading to line friction and leakage, but also affects the transmission of power signals. Furthermore, after the cables are connected, the joints need to be manually squeezed and fixed to ensure a tight connection between the two ends of the cable and eliminate contact gaps. However, the degree of manual squeezing and fixing is limited, and the cable under tension can cause the connection to loosen, resulting in poor contact at the cable connection, affecting the stable transmission of signals, and increasing the frequency of subsequent maintenance by the staff.
