Integrated universal CPCI guide rail

Abstract

The invention discloses an integrated universal CPCI guide rail, which is composed of a left guide rail plate, a right guide rail plate, a left rear guide rail plate and a right rear guide rail plate, wherein the left guide rail plate and the right guide rail plate are symmetrically fixed at the front part of a case, and mounted with a plurality of standard 160 mm CPCI board cards in cooperation; the left rear guide rail plate and the right rear guide rail plate are symmetrically fixed at the rear part of the case, and mounted with a plurality of standard 80 mm CPCI board cards in cooperation; the left guide rail plate, the right guide rail plate, the left rear guide rail plate and the right rear guide rail plate are fixedly connected with an upper cover and a lower cover of the case through bolts; the left guide rail plate and the right guide rail plate are connected with a CPCI bus backboard through bolts. The left guide rail plate, the right guide rail plate, the left rear guide rail plate and the right rear guide rail plate are respectively integrated components made of aluminum alloy materials and finished by a cutting and milling method, and the appearance structures conform to the standard CPCI specification. The integrated universal CPCI guide rail, disclosed by the invention, has the advantages of high strength, good anti-vibration and impact resistance, simple structure, convenient processing and installation and applicable to all standard CPCI board cards.

Description

technical field [0001] The invention relates to a board card guide rail inside a CPCI computer, in particular to an integral general-purpose CPCI guide rail. Background technique [0002] CPCI is a computer internal bus standard and is widely used in industrial and military fields. Computer cases using CPCI bus are divided into standard general-purpose CPCI cases and reinforced CPCI cases according to their internal guide rail frames. The guide rail frames of standard general-purpose CPCI cases adopt The guide rail frame of the reinforced CPCI chassis is formed by lapping special profiles, and a plurality of special slide grooves are processed on the inner wall of the chassis. [0003] Patent CN203191894U discloses a frame profile conversion module, which adopts a standard general-purpose CPCI chassis. become. The threaded strip is inserted into the T-shaped opening of the front beam and the middle beam, and the CPCI guide rail bayonet is inserted into the square opening o...

AI Technical Summary

Problems solved by technology

There are many guide rail frame parts in the cabinet, the installation and connection methods are complicated, the overall strength is low, and the anti-vibration performance is poor. The multiple square openings on the front beam and the middle beam and the T-shaped openings for installing threaded strips are difficult to realize by conventional cutting and milling methods.

In addition, the guide rail frame parts in the cabinet are all special profiles, and the procurement cost is high

[0004] Patent CN202494971U proposes a reinforced CPCI board, a chassis for installing and strengthening the CPCI board, and a reinforced CPCI computer, wherein the guide rail frame of the chassis for installing and strengthening the CPCI board is realized by processing step-shaped ladder grooves on the left and right inner walls of the chassis. Although the frame has high strength and good integrity, it is only suitable for special reinforced CPCI boards with high cost, and cannot be used for standard CPCI boards.
