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.

Abstract

A circuit board assembly with the adjustable clamping speed and upper and lower limiting sensors comprises a circuit board device (3) and a base fixing device. The circuit board device (3) comprises a rectangular body portion (30) and four fixing feet (31) located at the corners of the rectangle. The base fixing device comprises a base (1) and four installation frames (4) which are fixed to the base (1) and correspond to the four fixing feet (31) respectively. Each installation frame (4) is provided with a slot (40) where the corresponding fixing foot (31) is allowed to be inserted. An inner side clamping block (8) which is pressed unsymmetrically by a top pressure spring (83) and can stretch into each slot (40) is arranged at the inner-side portion, on the inner side, close to the body portion (30) of the circuit board device (3), of the slot (40) in the corresponding installation frame (4).

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to a circuit board assembly with adjustable clamping speed and upper and lower limit sensors. 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...
