Description

Combined VPX module case

Technical Field

The utility model relates to the field of machine manufacturing and product design, in particular to a combined VPX module case.

Background

The VPX module standard has been rapidly developed since the rapid growth of VME introduction, and is a new generation of embedded bus standard, employing the latest connector technology and high-speed serial interface technology. Compared with the similar bus, the bus has greater advantages in the aspects of data transmission bandwidth and structural performance, and is more suitable for the fields of modern national defense and aviation. The annual growth rate of global yield is kept above 20%, and the method is recognized as one of the technical fields with development prospects in the 21 st century under the background of large-scale application.

At present, the structure of VPX module can not satisfy the application under the increasingly high performance requirement of national defense and aviation field and more adverse circumstances, VPX module's high integration and high reliability and modular structural design need invest into more renewed consideration in the aspects such as heat dissipation and reinforcement, will satisfy the product at radio frequency and digit cross design, and interior modularization satisfies the heat dissipation and the electromagnetic shield requirement of product, consequently needs the design of a modular multislot VPX module structure to satisfy above requirement urgently.

Generally, there are two main ways to lay out the existing VPX module architecture on the current market:
