Description

Technical Field

[0001] The utility model relates to PCB fixing technology, in particular to a fastening type PCB fixing component. Background Art

[0002] The patent document with the application number "CN201611079667.0" discloses a PCB board fixing device for fixing a PCB board, which includes a housing provided with an installation position, and a first connecting member is arranged at the installation position; a support body for installing the PCB board, and the support body is fixedly connected with the housing through the first connecting member; feet for supporting the housing, the feet are arranged at the installation position of the housing and correspond to the first connecting member, and the vertical projection of the feet on the housing completely covers the vertical projection of the first connecting member on the housing. Since the PCB board is directly installed on the support body, the deformation amount of the support body is small and will not drive the PCB board to deform, ensuring the welding reliability of the electronic components on the PCB board. At the same time, the vertical projection of the feet on the housing completely covers the vertical projection of the first connecting member on the housing, and the first connecting member will be hidden by the feet also arranged at the installation position, making the appearance of the housing more flat and improving the appearance quality of the whole device.
