Background
The PCB is also called a PCB, and is an electrical connector for electronic components. The low-voltage cabinet is usually provided with a plurality of circuit boards which need to be installed and fixed, however, the circuit boards are welded and fixed in a hard connection mode, namely, the circuit boards are soldered and fixed by welding after being inserted and fastened. The circuit board fixed by the connection mode has a plurality of defects. For example, in a place with vibration, the copper sheet at the connection position of the circuit board can be broken due to the rigidity of the soldering tin, thereby affecting the communication of signals and the quality of a final product.
In addition, when the circuit board is manufactured, a technical edge is reserved on the edge of the circuit board, the technical edge needs to be cut off when the circuit board is used, but a burr edge is reserved on the cut circuit board or the edge, or a part of the edge of the circuit board is cut off. And the two results can lead to the circuit board size not meeting the specification when the circuit board is installed, and the installation back appears rocking easily to influence the normal use of equipment.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned not enough, provide a low-voltage cabinet circuit board of guaranteeing product quality and equipment normal use.
The purpose of the utility model is realized like this:
the utility model provides a low-voltage cabinet circuit board, is including installing the circuit board subassembly in the low-voltage cabinet, the circuit board subassembly is formed by two piece at least circuit board installations concatenation, and at least a circuit board is installed on another circuit board, has seted up the pad mounting hole on the circuit board of installation, and the bottom of the circuit board of installation is equipped with the pad, and the pad injects and installs in the pad mounting hole, a plurality of pad through-holes are seted up on the surface of pad, and the both sides of every circuit board are provided with the technology limit, and the circuit board has seted up two recesses with technology limit junction, and the technology limit sets up the lug at the recess, the same and mutually supporting of shape of recess and lug is connected circuit board and technology limit, a plurality of process holes have been seted up to the seam crossing dense cloth of recess and lug.
And a copper wire penetrates through the through hole of the bonding pad, one end of the copper wire is welded on the installed circuit board, and the other end of the copper wire is welded on the installed circuit board.
Compared with the prior art, the beneficial effects of the utility model are that:
the low-voltage cabinet circuit board is characterized in that a pad of one circuit board is inserted into a pad mounting hole of a mounted circuit board, a copper wire penetrates through a pad through hole, one end of the copper wire is welded on the mounted circuit board, the other end of the copper wire is welded on the mounted circuit board, the circuit boards are not connected in a hard mode, copper sheets at the joint of the two printed circuit boards cannot be broken due to the hardness of soldering tin, signal communication is guaranteed, and the quality of circuit board products is guaranteed.
Meanwhile, when the circuit board is used, the circuit board and the circuit board can be directly broken only by breaking off the technical edge, the circuit board broken off by breaking off the technical edge only leaves less burrs in the groove, and the burrs are left in the groove and cannot influence the normal use of the circuit board.
