Description

technical field

[0001] The invention relates to the field of circuit boards, in particular to an installation locking device for circuit boards with noise reduction and position limiting functions. Background technique

[0002] The installation and removal of the circuit board will affect the operation stability and reliability of the equipment using the circuit board, and will affect its maintainability. The installation of the current circuit board often adopts the method of opening a hole on the circuit board and inserting the circuit board through the fixing column arranged on the equipment rack. Holds the circuit board in place and can be removed for maintenance during use.

[0003] However, this installation mode first needs to open a through hole on the circuit board, which will affect the wiring layout of the circuit board itself, and will also affect the stability of the wiring around the through hole. Second, such vias affect the mechanical strength of the board ...
