The invention discloses a circuit board connection circuit 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 arranged at 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 ahollow cavity. The hollow 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 wallof 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 bedirectly connected to 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 connectedto 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 of the substrate is not occupied.
Description
technical field [0001] The disclosure of the present invention relates to the technical field of printed circuit board connection circuit, in particular to a circuit board connection circuit. 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 board connection circuits, the commonly used method is to use soldering connection method, and there are mounting holes reserved on the circuit board connection circuit. When soldering, the end of the terminal or the electronic component The pins pass through these mounting holes, and then welded to the circuit board connection circuit with solder. This welding method makes the terminals or electronic components all exposed outside ...
