Abstract

A chain-driven circuit board assembly is disclosed. The circuit board assembly comprises a circuit board apparatus (3) and a base fixing apparatus; the circuit board apparatus (3) comprises a rectangular body part (30) and four fixed pins (31) positioned in the corners of the rectangular body part respectively; the base fixing apparatus comprises a base (1) and four mounting frames (4), corresponding to the four fixed pins (31) respectively, fixed on the base (1); slots (40) for allowing the fixed pins (31) to be inserted are formed in the mounting frames (4); and each mounting frame (4) is provided with an inner side clamping block (8) which is biased by a top pressure spring (83) and capable of extending into the slots (40), wherein the inner side clamping block (8) is arranged in the inner side part, close to the inner side of the body part (30) of the circuit board apparatus (3), of the slots (40).

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to a circuit board assembly driven by a chain. 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 importantly, this installation mode will cause...
