Embodiment Construction

[0018] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0019] Such as figure 1 As shown, there are 16 slots in the backplane 1 of the chassis. The seventh and eighth slots are switching slots. These two slots are used to insert the VPX switching module. The switching module has 20 external network signal interfaces. The sixth slot of board 1 is the KVM slot, which provides VGA and USB signals to the outside, and the other slots on the backplane 1 are server module slots, and each slot provides USB and serial port signals to the outside. According to the characteristics of backplane 1, it can be seen that slots 7 and 8 are the slots with the most dense external interconnection of the chassis. These slots only define J0, J3~J6 signals, and J3~J5 connectors define 20 external networks. Signal, the two VPX connectors J1 and J2 have no defined signals, and the signals of other slots can be connected to the J1 and ...

Abstract

The invention provides a case hard connection structure based on a VPX rear IO board. A rear IO board of an exchange slot position is used as an adapter plate, and a special adapter slot position forinternal interconnection is not designed, so the number of modules installed in a limited space is increased, and the problems of infirm connection stability, poor impedance continuity and difficult installation and maintenance caused by a cable interconnection mode can also be avoided; a modular design is adopted, so the mounting difficulty is reduced; a large number of network differential signals needing to be externally connected are directly led out from the rear IO board, no wiring processing is carried out on the backboard, and the quality of the provided network signals is better; thesize of the rear IO board is flexibly designed according to the size of equipment to complete internal interconnection; a standard VPX connector is used for hard connection, and high-speed signals canbe switched over; and the hard connection structure can also avoid high production and maintenance cost caused by the connection mode of the flexible printed board.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a chassis hard connection structure based on a VPX rear IO board. Background technique [0002] VPX is a series of standards formulated by the VITA organization, including basic specifications, mechanical structures, signal definitions, etc. According to the standard, VPX equipment is composed of a backplane and a front card functional module. The functional module is plugged into the front of the backplane, and an optional rear IO board is plugged into the back of the backplane. In the application, in addition to integrating the backplane and functional modules, the VPX equipment also needs to lead the signals of each functional module to the external connector of the equipment to complete the internal connection. The internal connection of the chassis can be divided into three types: cable interconnection, flexible printed board interconnection and hard connectio...
