Description

TVS/ESD protector assembly Technical Field The utility model relates to the technical field of diodes, in particular to a TVS/ESD protector component. Background An ESD diode, also known as an electrostatic protection diode, is a device used to protect electronic components from electrostatic discharge (ESD). TVS diodes, also known as TVS diodes, are a new type of high-efficiency circuit protection device developed in the zener diode technology. The TVS/ESD protection device has the characteristics of rapid response and high integration level. When in actual use, if welding errors occur during welding pins of the TVS/ESD protection device, the pins are required to be disassembled, the pins are easy to damage and break in the disassembling process, and further the secondary welding is affected, so that one-time welding errors are easy to cause, and the TVS/ESD protection device cannot be used. To solve the above problems, the present utility model provides a TVS/ESD protector assembly. Disclosure of utility model In order to overcome the technical defects, the utility model aims to provide a TVS/ESD protector assembly, wherein after the lower transverse section of a connecting pin is matched with a connecting groove, the lower transverse section of the connecting pin is welded on an electronic board, and finally the upper transverse section of the connecting pin is welded with a pin, so that the technical problem in the background art is solved. In order to solve the technical problems, the TVS/ESD protector component comprises a chip body, pins are welded at the upper end and the lower end of the chip body respectively, the two pins are positioned at the left end and the right end of the packaging piece respectively, connecting grooves are symmetrically formed in the left end and the right end of the packaging piece, the tail ends of the pins extend out of the connecting grooves, connecting pins are installed in the connecting grooves in a matching mode, the upper surfaces of the connecting pins are in contact with the pins, one ends of the connecting pins are installed in the connecting grooves in a matching mode, the other ends of the connecting pins are welded on an electronic board, and after the connecting pins are checked, the connecting pins and the pins are welded. Preferably, the connecting pin is Z-shaped, and the lower transverse section of the connecting pin is welded on the electronic board. Preferably, the upper transverse part of the connecting pin is contacted with the pin, the upper transverse part of the connecting pin is arranged in the connecting groove in a matching way, and the connecting pin is connected with the pin through welding, so that the connection stability is improved. Preferably, the pin and the inner wall of the connecting groove enclose a U-shaped groove, and the upper surface of the upper transverse part of the connecting pin is provided with a notch, so that the cross section of the upper transverse part of the connecting pin is U-shaped, and the upper transverse part of the connecting pin is installed in the connecting groove in a matching way. Preferably, the pins are arranged in the notches in a matching way, so that the welding area of the pins and the connecting pins is increased, and the connection stability is improved. The utility model has the beneficial effects that: After the lower transverse section of the connecting pin is matched with the connecting groove, the lower transverse section of the connecting pin is welded on the electronic board, and finally the upper transverse part of the connecting pin is welded with the pins, so that even if an engineer welds the connecting pin wrongly, only the connecting pin is required to be dismantled, and even if the connecting pin is damaged, the welding use of the chip body is not influenced.
