The metal plate support solves the problem that the PCB cannot be fixed in parallel due to space limitation, and saves the using quantity of the metal plate support, so that the raw material cost is saved. The operation mode of using the sheet metal support for installation is simple, the firmness is good, and an effective method is provided for the parallel installation of the PCB.

Description

A panel beating support for PCB board parallel fixation

Technical Field

The utility model relates to a panel beating support, concretely relates to a panel beating support that is used for PCB board parallel fixation.

Background

The existing electronic control equipment, such as a frequency converter and the like, mostly adopts a Printed Circuit Board (PCB), and often a plurality of PCBs are provided in the same product, and the PCBs are connected through data lines to cooperatively work. In the prior art, a single PCB is fixed by using a single sheet metal bracket, in actual needs, two PCBs are often limited to be fixed in a parallel mode, however, the existing space is not enough to use a conventional mode of separately fixing two sheet metal brackets. How to fix two PCB boards in parallel under the insufficient condition of space is the problem that research and development personnel often met.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the prior art, the utility model aims to provide a panel beating support for PCB board parallel fixation.

In order to achieve the above object, the present invention provides the following technical solutions:

a sheet metal bracket for parallel fixing of a PCB (printed circuit board) comprises a bracket main body, wherein two opposite end surfaces of the bracket main body are respectively a first fixing surface and a second fixing surface, a plurality of fixing through holes are formed in the same axis of the end surface of the bracket main body, a plurality of male and female studs and a plurality of press riveting studs are respectively arranged on the first fixing surface and the second fixing surface, a pair of male and female studs and a pair of press riveting studs correspond to one fixing through hole, and external thread ends of the male and female studs penetrate through the fixing through holes and are fixed with internal threads of the press riveting studs; the two PCBs are respectively fixed on the male and female studs of the first fixing surface and the press riveting studs of the second fixing surface.

Furthermore, the support main body is of a long strip-shaped structure.

Furthermore, a plurality of mounting blocks are arranged on the support main body.

Furthermore, the two ends of the support main body are respectively provided with an extension plate along the width direction of the same side of the support main body, and the tail end of the extension plate is provided with a mounting block vertical to the extension plate.

Furthermore, the end face of each mounting block is provided with a mounting hole.

Has the advantages that: the utility model provides a panel beating support for PCB board parallel fixation uses a panel beating support can carry out parallel fixation to two PCBs, has solved because space restriction leads to the problem that the PCB board can not parallel fixation, has practiced thrift the use quantity of panel beating support simultaneously to the raw materials cost has been saved. The operation mode of using the sheet metal support for installation is simple, the firmness is good, and an effective method is provided for the parallel installation of the PCB.
