Detailed Description

The present invention will be described in detail with reference to the following examples.

As shown in fig. 1-10, an improved CPCI chassis comprises a chassis integral frame composed of a left side plate 11, a right side plate 12, an upper cover plate 13 and a lower cover plate 14, wherein front cross beams 15 are correspondingly arranged at the front parts of the upper cover plate 13 and the lower cover plate 14, rear cross beams 16 are correspondingly arranged at the rear parts of the upper cover plate 13 and the lower cover plate 14, the CPCI chassis further comprises a CPCI guide rail group and a metal guide rail group, the CPCI guide rail group comprises CPCI guide rails 17 correspondingly arranged on the upper cover plate 13 and the lower cover plate 14, the metal guide rail group 18 comprises metal guide rails 18 correspondingly arranged on the upper cover plate 13 and the lower cover plate 14, CPCI plug-in units 19 are inserted on the CPCI guide rails 17, and metal plug units 20 are inserted on the metal guide rails 18. The front beam 15 and the rear beam 16 are both provided with inner nut beams 21 for fixing the metal guide rail 18. The application range of the CPCI chassis is increased by arranging the internal nut beams 21 on the front beam 15 and the rear beam 16, and the metal insert 20 can be installed by fixing the metal guide rails 18 on the internal nut beams 21.

In a further optimized embodiment, two ends of the metal guide rail 18 are provided with first threaded holes 18a, the inner nut beam 21 is provided with first holes 21a matched with the first threaded holes 18a, and bolts pass through the first holes 21a and the first threaded holes 18a to connect the metal guide rail 18 and the inner nut beam 21.
