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

Provided is a circuit board assembly with an alarm. 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) respectively arranged on rectangular corners. The base fixing device comprises a base (1) and four installation frames (4) which are fixed on the base (1) and respectively correspond to the fixed feet (31). Inserting grooves (40) in which the fixed feet (31) can be inserted are arranged in the installation frame (4). Inner side clamp blocks, which are pressed by pressing springs (83) in an inclined manner and are capable of stretching into the inserting grooves (40), are arranged on inner side parts, near the inner sides of the body part (30) of the circuit board device (3), of the inserting grooves, on the installation frames (4).

Description

Technical field [0001] The invention relates to the field of circuit boards, in particular to a circuit board assembly with an alarm. Background technique [0002] The installation and removal of the circuit board will affect the stability and reliability of the operation of the equipment using the circuit board, and will affect its maintainability. The current circuit board installation often adopts opening holes on the circuit board and inserting the circuit board through a fixed post arranged on the equipment rack. The fixed post has a locking structure that can be elastically contracted or has an external thread that can tighten a nut. Fix the circuit board in place and be able to disassemble the circuit board to facilitate maintenance during use. [0003] However, this installation mode first requires opening a through hole on the circuit board, which will affect the wiring layout of the circuit board itself, and will affect the line stability of the wiring around the through...
