Description

Technical Field

[0001] The present invention relates to the technical field of spacecraft communication systems and the like, and in particular to a VPX chassis. Background Art

[0002] The VPX chassis has a built-in ultra-high-speed interconnect backplane (VPX bus), which is suitable for high-speed interconnected electronic product chassis. The VPX chassis has strong mechanical resistance to vibration and impact, and is particularly suitable for satellite-borne, rocket-borne, and missile-borne electronic products.

[0003] In spacecraft electronic products, the effective space utilization of the VPX chassis is lower than that of traditional structural modules because the VPX chassis has a built-in high-speed interconnect baseboard and the locking device between the plug-in board and the chassis has high requirements for anti-mechanical properties.

[0004] In spacecraft where space resources are scarce, spacecraft electronic products adopt VPX chassis or traditional structures according to their characteristics. How to improve the effective space utilization of spacecraft is the technical background of the present invention. Summary of the invention

[0005] The present invention designs the VPX chassis and the traditional structural module into an integrated machine, thereby improving the effective space utilization rate of the spacecraft in a spacecraft with scarce space resources.

[0006] The technical solution adopted by the present invention is as follows:

[0007] An integrated structure compatible with a VPX chassis includes a main module, a monitoring PCB board, a power PCB board, a baseband PCB board, a front cover and a rear cover. The monitoring PCB board is installed at the middle and lower part of the front of the main module, the power PCB board is installed at the upper part of the front of the main module, the baseband PCB board is installed at the back of the main module, the front cover is installed at the front of the main module, and the rear cover is installed at the back of the main module.

[0008] Furthermore, the main body module is provided with an SMA electrical connector.

[0009] Furthermore, there are six SMA electrical connectors.

[0010] Furthermore, a network port electrical connector is provided on the main body module.

[0011] Furthermore, a monitoring signal electrical connector is provided on the main body module.

[0012] Furthermore, there are three monitoring signal electrical connectors.

[0013] Furthermore, a power connector is provided on the main body module.

[0014] The present invention also provides a VPX chassis, wherein the integrated structure compatible with the VPX chassis is installed on the front side or the back side of the VPX chassis.

[0015] Furthermore, the integrated structure compatible with the VPX chassis is installed on the front or back of the VPX chassis by screws.

[0016] The beneficial effects of the present invention are as follows: in a spacecraft where space resources are scarce, the VPX chassis and traditional modules are structurally designed as an integrated machine, which can improve the effective space utilization of the spacecraft.
