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

The invention discloses a circuit board assembly driven by a chain and provided with a locking indicator lamp. The circuit board assembly comprises a circuit board device (3) and a base fixing device. The circuit board device (3) comprises a rectangular body part (30) and four fixed feet (31) located at the corners of the rectangle respectively. The base fixing device comprises a base (1) and four mounting frames (4) which are fixed to the base (1) and correspond to the four fixed feet (31) respectively. Inserting grooves (40) allowing the fixed feet (31) to be inserted are formed in the mounting frames (4), and inside clamping blocks (8) which are biased by the jacking and pressing springs (83) and can stretch into the inserting grooves (40) are arranged at the inner sides, close to the inner side of the body part (30) of the circuit board device (3), of the inserting grooves (40) of the mounting frames (4).

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to a circuit board assembly driven by a chain and provided with a locking indicator light. 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 im...
