Problems solved by technology

[0006] For the welding of ultra-thin coaxial cable connectors, traditional manual welding or hot bar welding has considerable limitations, or even cannot be completed
[0007] (See Table 1) The wire core diameter of the 40th wire is only 0.08mm. If the connector is welded by hand (or hot bar welding), the damage to the wire will be inevitable. The reason is that the wire core is too thin, which directly leads to a decrease in conductivity. , or even burn the wire

Description

technical field [0001] The invention relates to a wire harness processing device and a process thereof, in particular to a laser welding device and a welding process for an ultra-fine coaxial cable connector. Background technique [0002] In the wire harness industry, traditional connector welding is generally done by manual soldering and automatic soldering iron soldering (hot bar welding). However, with the advancement of science and technology, the diameter of wires is becoming smaller and smaller. , and also has a shielding layer. This kind of cable with a shielding layer is called a coaxial cable, and a line that is arranged together by multiple coaxial cables is called a cable, such as; Ultra-thin coaxial cables are used in scientific and technological equipment, which is also the inevitable result of technological progress. Table 1 is the AWG cable specification table. [0003] [0004] Table 1 AWG cable specification table [0005] Due to the continuous developm...
