Circuit board assembly easy to install and uninstall and guided by guide rod

Abstract

Provided is a circuit board assembly easy to install and uninstall and guided by a guide rod. The circuit board assembly comprises a circuit board device (3) and a pedestal fixing device. The circuit board device (3) comprises a rectangular body portion (30) and four fixing pins (31) on the corners of the rectangular body portion. The pedestal fixing device comprises a pedestal (1) and four installing racks (4) fixed to the pedestal (1) and corresponding to the four fixing pins (31) respectively. Each installing rack (4) is equipped with a slot (40) into which the corresponding fixing pin (31) can be inserted. The inner side portion, close to the inner side of the body portion (30) of the circuit board device (3), of the slot (4) of each installing rack (4) is provided with an inner-side clamping block (8) which is biased by a pushing spring (83) and which can be inserted into the slot (40).

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to a circuit board assembly which is easy to disassemble and is guided by a guide rod. 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 itself. More import...

Problems solved by technology

[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 line stability of the traces around the through hole

Second, such vias will affect the mechanical strength of the board itself

More importantly, this installation mode will cause an imbalance in the mechanical force on the circuit board itself during the fastening process, resulting in the breakage of the circuits in each layer of the circuit board.
