Abstract

The invention discloses a square shielding case and an assembling tool thereof. The problems that as for a traditional shielding case, the structure is complex, the production cost of an enterprise ishigh, the assembling difficulty is high, welding is poor, and flux leakage is prone to occurring are solved. The square shielding case formed by sequentially welding a left side plate, a right side plate, a top plate, a bottom plate and a rear cover and the assembling tool for assembling the square shielding case are mainly included. According to the shielding case, the structural design is simple, the production and manufacturing cost is low, a routine thought is broken through, and the shielding demand of an electronic instrument is met through the extremely simple structure; according to the assembling tool, the structural design is simple and ingenious, operation is easy, the assembling accuracy is high, it is effectively ensured that welding joints of the shielding case are smooth, flat and free of flux leakage in welding, and the phenomena of slag inclusion and incomplete penetration are avoided; and the operation efficiency of workers is further greatly improved, the reject ratio of a product is greatly decreased, the very high practicability is achieved, considerable economic benefits can be created for the enterprise, and considerable social benefits can be created for the society.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a square shielding cover for a microcomputer and a monitor used in a power-frequency electromagnetic field environment and a high-frequency pulse interference field and an assembly tool thereof. Background technique [0002] During the live test of electric equipment, in order to prevent the influence of the power frequency electromagnetic field or the high frequency pulse on the test instruments and equipment, such as microcomputers, monitors, etc., it is necessary to set up shielding covers outside the relevant test instruments and equipment. The function of the shielding cover is to surround the interference source of the system by the shielding body to prevent the interference electromagnetic field from spreading outward; at the same time, the entire device or system is surrounded by the shielding body to prevent them from being affected by the ext...
