An integral universal cpci guide rail

Abstract

The invention discloses an integral general-purpose 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; Multiple standard 160mm CPCI boards are installed together, the left rear guide rail plate and the right rear guide rail plate are symmetrically fixed on the rear of the chassis, and are installed in conjunction with multiple standard 80mm CPCI boards, the left guide rail plate, right guide rail plate, left rear guide rail plate, The right rear guide rail plate is connected to the upper and lower covers of the chassis by screws, and the left guide rail plate and right guide rail plate are connected to the CPCI bus backplane by screws. The left guide rail plate, right guide rail plate, left rear guide rail plate, and right rear guide rail plate are integral parts respectively, which are processed by cutting and milling with aluminum alloy materials, and the appearance and structure conform to the standard CPCI specification. The integral universal CPCI guide rail has high strength, good vibration and shock resistance, simple structure, convenient processing and installation, and is suitable for all standard CPCI boards.

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.
