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 resistant to abrasion comprises a circuit board device (3) and a base fixed device, wherein the circuit board device (3) comprises a rectangular body part (30) and four fixed legs (31), the four fixed legs (31) are respectively arranged at corners of a rectangle, the based fixed device comprises a base (1) and four installation racks (4), the four installation racks (4) are fixed on the base (1) and are in respective correspondence to the four fixed legs (31), slots (4) are arranged in the installation racks (4) and used for the fixed legs (31) to insert, the installation racks (4) are provided with inner-side clamping blocks (8) at the inner side parts, near to the inner side of a body part (30) of the circuit board device (3), of the slots (40), and the inner-side clamping blocks are biased by jackingsprings (83) and can extend into the slots (40).

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to an anti-wear circuit board assembly. 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 unbala...
