A plurality of electronic elements are integrated on a circuit board of the high-power high-frequency switching power supply, and the electronic elements are installed on the circuit board and then are installed in a heat dissipation bracket or a power supply box after being subjected to reflow soldering. Because the position that part component need correspond with the power pack on the circuit board cooperates and is fixed, in the reflow soldering process, if because of electronic component's position or plane degree installation deviation, can lead to follow-up worker station unable installation or install not in place, can lead to the product quality problem necessarily, probably need the desolder rework when serious.
Disclosure of Invention
For satisfying the requirement of a plurality of component plane degree uniformity of power supply circuit board, the utility model aims to provide a frock is rectified to direct current switching power supply electronic component plane degree.
In order to achieve the above purpose, the utility model adopts the technical proposal that:
the flatness correction tool for the electronic element of the direct-current conversion power supply comprises a bottom plate, wherein an invagination positioning groove corresponding to the size of a circuit board is arranged in the middle of the bottom plate, and rotary press blocks are respectively arranged on the outer sides of four corners of the positioning groove; the top surface of the sliding base is provided with a pair of positioning pins, the upper seat is provided with positioning holes matched with the positioning pins, a plurality of limiting grooves are respectively processed on one sides of the sliding base and the upper seat facing the circuit board, and when the upper seat is installed on the sliding base, the upper seat and the limiting grooves of the sliding base form limiting cavities corresponding to the electronic elements in shape respectively.
Further, one row of magnets are installed at the bottom of the sliding base, and two rows of magnets are installed on the bottom plate corresponding to the stroke of the sliding base.
Furthermore, the rotary pressing block comprises a pressing block and a screw, the pressing block is rotatably installed on the bottom plate through the screw, and when the pressing block rotates, part of the pressing block enters the position above the positioning groove to limit the circuit board or is separated from the position above the positioning groove.
Furthermore, barrier strips are respectively installed on the periphery of the top surface of the bottom plate.
After taking above technical scheme, the beneficial effects of the utility model are that: the electronic component that has the cooperation requirement to with the power pack sets up correction frock, utilizes the cooperation of sliding bottom and seat of honour to form the cavity that corresponds with electronic component, stabilizes electronic component in the cavity, and is spacing with magnet with sliding bottom simultaneously, guarantees that electronic component can not take place to warp at transportation, reflow soldering etc. in-process, ensures its plane degree and uniformity.
