Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a switching device for a semiconductor single-core tube. Background technique [0002] Semiconductor single-core tubes are widely used in fiber lasers or direct processing applications due to their compact structure, light weight, stable performance, good reliability, long life, and high electro-optic conversion efficiency. [0003] When the semiconductor single-core tube is working, its positive and negative pins are electrically connected to an external power supply device through a power line, and usually the positive and negative pins are connected to the power line by welding. And because the structure of the semiconductor single-core tube is compact, its positive and negative pins are very close to each other. When welding a power line on one pin of the semiconductor single-core tube, it is easy to touch another pin, causing the two pins to short circuit. When dism...

Problems solved by technology

However, due to the compact structure of the semiconductor single-core tube, its positive and negative pins are very close together. When welding the power line on one pin of the semiconductor single-core tube, it is easy to touch the other pin, causing a short circuit between the two pins.

When dismantling the power line on one pin of the semiconductor single-core tube, it is also easy to have a short circuit between the two pins

Moreover, when soldering or removing the power cord, in order to melt the solder, the temperature of the soldering iron must be set above 300°C, and the power cord is generally close to the shell of the semiconductor single-core tube, so the heat of the soldering iron is easily transferred to the semiconductor. In the shell of the single-core tube, the welding point in the shell is caused to move (smile effect). The more times the power cord is welded or removed, the more obvious this effect is, which in turn shortens the service life of the semiconductor single-core tube.
