Problems solved by technology
[0003]In order to solve the defect that the welding end of the existing hollow pin and the solder are prone to desoldering, the present invention provides a hollow pin that prevents desoldering. The structure of the soldering pin can effectively increase the adhesion after soldering and prevent the soldering end of the pin from peeling off easily from the solder

Embodiment Construction
[0015] like figure 2 image 3 A desoldering-proof hollow pin is shown, which includes a round pin 1 , the lower part of which is a welding pin 4 , and a plastic positioning ring 3 is provided near the round pin 1 near the welding pin 4 . The round needle 1 and the welding pin 4 are conductors connected to each other, and a through hole 5 is provided on the welding pin 4 . The direction of the through hole 5 is vertical and penetrates the cylindrical surface of the welding pin 4 . And the setting position of the through hole 5 is close to the bottom surface of the welding pin 4, so as to ensure that the through hole 5 is not blocked after the welding pin 4 is embedded. When the hollow pin is connected to the circuit board 6, the welding pin 4 is inserted into the circuit board 6, the bottom of the plastic positioning ring 3 is in contact with the circuit board 6, and the bottom surface exposed at the lower end of the welding pin 4 is connected to the solder 2 for welding.

The invention discloses a desoldering prevention hollow contact pin, which is applied to a circuit board connector. The contact pin comprises a round pin, the lower part of the round pin is a welding pin, a plastic positioning ring is also arranged between the round pin and the welding pin, the welding pin is also provided with a through hole, and the through hole is vertical and passes through a cylindrical surface of the welding pin. The invention ensures that the welding of the hollow contact pin to a circuit board is equivalent to the adding of a soldering tin transverse bolt by arranging the through hole on the welding pin, thereby effectively strengthening welding strength, overcoming the defect that a welding end of the hollow contact pin and soldering tin are easy to desolder, simultaneously enlarging the conduction area of the soldering tin and the welding pin, and contributing to the improvement of the quality of circuits.
Description
technical field [0001] The invention relates to a hollow pin, in particular to an anti-soldering hollow pin. Background technique [0002] The hollow pin is a device used as a connector (ground connector) on the circuit board (PCB), and it functions as a circuit conduction. like figure 1 As shown, the pins are usually in the shape of tinned red copper round pins, installed on the upper or lower part of the circuit board, connected to the copper foil of the circuit pad through soldering, and the top of the pin is connected to other line sockets. The current welding method of the hollow pin on the circuit board is directly installed on the component hole of the circuit board, and soldered to the pad by soldering, but due to various reasons, such as the oxidation of the pin plating, the incompleteness of the plating and the copper round pin Plating, etc., it is very easy to desolder after wave soldering (the pin and the solder at the soldering point are completely separated o...
