Abstract

The invention discloses a circuit board which comprises a substrate and a metal hot-melt nut. A metal contact point is arranged on the surface of the substrate. At least one mounting hole is arrangedat a position where the metal contact point is located, and the mounting hole penetrates through two surfaces of the substrate. The metal hot-melt nut is internally provided with a hollow cavity. Thehollow cavity is internally provided with an internal thread. The metal hot-melt nut is embedded in the mounting hole, and an outer wall of the metal hot-melt nut and an inner wall of the mounting hole are fixed. The metal hot-melt nut is electrically connected to the metal contact point. In practical applications, a wire, wire connection terminal or electronic component can be directly connectedto the internal thread of the hollow cavity of the metal hot-melt nut through a metal bolt, thus the wire, wire connection terminal or electronic component is electrically connected to the metal contact point on the substrate through the metal hot-melt nut. Since the metal hot-melt nut is directly embedded in the substrate, the metal hot-melt nut is firmly fixed to the substrate, and the space ofthe substrate is not occupied.

Description

technical field [0001] The invention relates to the technical field of printed circuit boards, in particular to a circuit board. Background technique [0002] In general industrial machine controllers and electrical and electronic products, in order to control and realize some or all functions, multiple printed circuit boards are built into the equipment as design circuits to realize control using electrical signals. [0003] However, in order to connect wires on these printed circuit boards, the current common method is to use soldering connection method, and a mounting hole is reserved on the circuit board. When soldering, the end of the terminal, or the pin of the electronic component Through these mounting holes, and then welded to the circuit board with solder, this welding method makes the terminals or electronic components all exposed outside the circuit board, which not only takes up space on the circuit board, but also prevents the terminals or electronic components...
