Electronic equipment subrack and assembling method thereof

Abstract

The invention relates to an electronic equipment subrack. The electronic equipment subrack is characterized in that when an upper guide rail plate and a lower guide rail plate are horizontally placed,the projection top view is rectangular, the subrack comprises a middle section of convex flat plate and a section of bent vertical plate positioned at the edge, and more than two guide rail grooves vertical to the vertical plate are formed in the convex flat plate; riveting nuts used for installing a circuit mother board are arranged on the bent vertical plate, and via holes used for installing parts are formed on the plane adjacent to the vertical plate and the plane away from the vertical plate; the side plates, a cross beam and the fixing lugs are provided with the connecting holes matchedwith the via holes of the upper guide rail plate and the lower guide rail plate respectively, nut holes are formed in the length direction of the cross beam and the two ends of the cross beam, and nut holes are formed in the two adjacent planes perpendicular to each other of a cover plate fixing block. The invention further relates to an assembling method of the electronic equipment subrack. Theelectronic equipment subrack has the obvious advantages of being small in number of parts, few in variety and low in manufacturing difficulty and being easy to assemble.

Description

technical field [0001] The invention belongs to the technical field of production and manufacturing of electric power system electronic equipment, and in particular relates to an electronic equipment insertion box with lower cost and more convenient assembly. Background technique [0002] GB / T19520 "Electronic Equipment Mechanical Structure 482.6mm (19in) Series Mechanical Structure Dimensions" stipulates the basic dimensions of 482.6mm (19in) series panels, subracks, chassis, racks and cabinets. At present, the existing electronic equipment sub-boxes in the market that meet the requirements of this standard usually include front beams, side ears, side panels, rear beams, nut strips, motherboard mounting beams, profile guide rails, guide rail heads, cover plate fixing blocks, etc. Numerous major parts. The main problems are: 1. There are too many parts in the electronic equipment box; 2. The parts need to be manufactured with molds or profiles; 3. The key dimension chain (i...

AI Technical Summary

Problems solved by technology

The main problems are: 1. There are too many parts in the electronic equipment box; 2. The parts need to be manufactured with molds or profiles; 3. The key dimension chain (including the relative position and distance between the guide rails, the board panel mounting surface and The distance between the circuit board, the relative position of the guide rail groove and the connector on the circuit board) contains many parts, and it is difficult to ensure the assembly accuracy of the guide rail; 4. The assembly of the product is difficult
