[0003] In the process of using the above circuit board daily, it is found that, in order to facilitate wiring, the output of the circuit board is often a needle-shaped pin and is connected by inserting a dupont wire on the needle-shaped pin, and the inventor found in daily work that during the insertion process, electric arc is prone to occur, and when the dupont wire is inserted into the needle-shaped pin, it is usually inserted slowly due to uncertainty of whether it is directly opposite the pin (fast insertion of the dupont wire when not directly opposite the pin can easily cause the pin to bend), thereby causing the electric arc to exist for a long time, which has a safety hazard. UTILITY MODEL CONTENTS
[0004] The present application aims to provide a PCBA circuit board with a positioning mechanism, which aims to solve the technical problem of long electric arc existence time caused by slow insertion of the dupont wire into the needle-shaped pin due to uncertainty of whether it is directly opposite the pin.
[0005] To achieve the above-mentioned purpose, the present application provides a PCBA circuit board with a positioning mechanism, which includes a DC power module PCBA circuit board, an output module and an indicator light, wherein the DC power is input from a DC power interface (the DC power interface can be connected to a 5.5*2.1mm power supply), and the voltage is adjusted by a processing module and output from the output module, wherein the output module is composed of an output pin matrix and a grounding pin matrix, the output pin matrix includes a 12V power output pin matrix, a 5V power output pin matrix and a 3.3V power output pin matrix, wherein the adjusted DC power is output from the output pin matrix in the output module, and a second positioning component is arranged on each pin in the output pin matrix, wherein the second positioning component includes a rubber sleeve, and the rubber sleeve extends out of the upper end of the pin to form a sharp end structure.
[0006] The effect achieved by the above component is that when the power supply regulated by the DC power module PCBA circuit board is needed, one end of the DuPont wire is connected to the powered device and the other end is inserted into the pin. Since the tip structure protrudes from the pin, and both the rubber sleeve and the tip structure are made of insulating rubber material (the insulation performance of insulating rubber is 20 times higher than that of air), the power supply cannot easily break through the insulating rubber to cause electric arc leakage when the DuPont wire interface is pressed against the tip structure. When the DuPont wire interface is pressed against the tip (at this time, the DuPont wire interface is in a position opposite to the pin), quickly press the DuPont wire to quickly extrude the tip structure and deform the rubber sleeve, so that the DuPont wire interface can quickly fit on the needle-shaped pin, reducing the existence time of electric arc.

[0012] The effect achieved by the above component is that when the plate body is installed, the plate body is installed on the support by passing the bolt through the mounting hole, and when the plate body needs to be removed, the clamping piece can be pulled apart to expose the mounting hole (at this time, the long strip of elastic pieces is bent) to tilt and take out the plate body. When installing, there is no need to remove the bolts on the support, pull apart the clamping piece to expose the mounting hole, tilt and insert one side of the plate body into two bolts on one side, then press down the plate body to make the other side of the two mounting holes clamped on the other side of the two bolts, and when the clamping piece is loosened, the clamping piece is guaranteed to block the edge of the mounting hole under the elastic force of the long strip of elastic pieces, and then the bolts are tightened to clamp the plate body and complete the installation. Since the first positioning component is provided, the bolts do not need to be completely removed and then aligned with the four mounting holes for installation when the plate body is replaced and installed. Only the bolts need to be loosened to remove the plate body, and then the plate body can be clamped in the loosened bolts and then tightened.
