Instrument of novel circuit board module structure

Abstract

The invention discloses an instrument of a novel circuit board module structure. The instrument comprises a shell and a circuit board module arranged in the shell and is characterized in that the circuit board module comprises four circuit boards which are assembled to form a square frame structure in the upper direction, the lower direction, the front direction and the back direction, and abutting connection portions of the adjacent circuit boards are in circuit connection through plug-in connectors and provided with bayonets and bayonet flanges, wherein the bayonets and bayonet flanges are used for steady connection and are clamped with each other. According to the circuit board module structure, circuit connection and structural fixation between the circuit boards are achieved by means of the fixing effect of the plug-in connectors, it is ensured that the circuit board module is steadily and fixedly installed in the shell through the plug-in connectors in cooperation with a clamping structure, limiting reinforcing flange bodies and the like, no clamping grooves or other structures need to be formed in the shell of the instrument, no screws or other parts are needed, disassembly and assembly are convenient, the processing technology of the instrument is simplified, the product cost is reduced, the structure of the instrument has the good radiating effect, and the instrument is safe and reliable.

Description

technical field [0001] The invention relates to a power meter device, in particular to a meter with a novel circuit board module structure. Background technique [0002] Most of the existing small power meter devices are composed of a large circuit board (circuit board) or a number of small circuit boards arranged in parallel in the casing and housing. In order to ensure the stability of the structure, a large number of circuit boards are usually required. Connecting and fixing accessories, the assembly and welding process is complicated, and the manufacturing cost is high. And the use of an integrated large circuit board takes up more space in the horizontal direction, and the design of a multi-layer circuit board usually cannot achieve a good heat dissipation effect when the volume of the instrument is limited, which affects the service life of electronic components and power consumption. safe operation of the system. Contents of the invention [0003] In view of the a...
