Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a pin device of a circuit board and a circuit board. Background Art

[0002] Circuit board is also called printed circuit board, circuit board, PCB board, etc. It is an indispensable part of electronic equipment, which makes the circuit miniaturized and intuitive, and plays an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit board is mainly composed of pads, vias, mounting holes, wires, components, connectors, filling, electrical boundaries, etc. Circuit board is also divided into single-sided board and double-sided board. Single-sided board is the most basic PCB, with parts concentrated on one side and wires concentrated on the other side. Double-sided boards have wires on both sides, so more complex circuit connections can be achieved. Existing circuit boards generally use mounting pins to establish electrical connections with electronic components. Since the pins are generally mounted on the surface of the circuit board by stamping and are an integrated structure, during later use, the circuit board may be damaged or corroded by water, etc., resulting in damage to the leads installed on the pins, making it impossible to supply power normally. It is often necessary to weld conductive wires for conduction, and on existing pins, generally no holes are reserved for additional lead connections, which makes wiring difficult and easily causes virtual connections, making it inconvenient to use safely for a long time. At the same time, since commonly used pins are stamped structures, they cannot be replaced individually after being damaged, and it is inconvenient to disassemble the damaged pins and reinstall new pins to repair the equipment, which is not conducive to improving the service life of the circuit board.
