Description

PCB fixing device

Technical Field

The utility model belongs to the technical field of PCB installation, and particularly relates to a PCB fixing device.

Background

When the PCB needs to be fixed on an inclined plane with a certain included angle with the demoulding direction of the plastic part, the plastic part is limited by a process in the manufacturing process, so that the manufactured fixing sleeve has the optimal assembly direction along the demoulding direction, and the fixing sleeve of the PCB is not perpendicular to the PCB. As shown in fig. 1, because there is a certain contained angle between the through hole of the PCB board 1 and the PCB board, when the screw is connected with the fixing sleeve 3, the top of the screw cannot be attached to the PCB board 1, if the screw is screwed down, the lower edge of the top of the screw will damage the PCB board 1, and if the screw is not screwed down, the relative shaking of the PCB board and the plastic part 2 will be caused.

Therefore, providing a new PCB board fixing device is a technical problem to be solved by those skilled in the art.
