Description

TECHNICAL FIELD

[0002] In actual connection, cable heads are connected in various ways such as crimping, welding, and twisting. Cable head welding is a key process for realizing electrical connection of cable conductors and connecting terminals through heating and fusion, which is commonly used in the fields of power, communication, and industrial equipment installation. It mainly adopts copper welding, tin welding, or laser welding, and needs to ensure that the conductor is clean and fixed firmly, and then complete the fusion by controlling the temperature and time to form a low-resistance, high-strength conductive joint. The welding quality directly affects the stability and safety of the circuit, and the reliability needs to be verified through welding seam appearance inspection and conductivity test. It is suitable for terminal or intermediate connection operation of copper, aluminum, and alloy cables.

[0003] In the existing welding process of cable heads, two to three workers are often needed to manually operate and weld. Although some welding processes use welding supports, the supports generally support the main cable and cannot provide greater assistance to the welding process. This manual welding method not only takes a lot of time and effort, but also easily causes safety problems. In the welding process, the cable head also needs to be manually supported, which has low precision. In addition, after the welding is completed, the flash needs to be manually cut and the molten edge needs to be manually ground. The post-welding processing not only takes a lot of time, but also easily causes the problem of grinding too much or too little due to grinding errors. In view of the above situation, the present application provides a cable head welding support to solve the above problems. SUMMARY
