A signal connection system between a network switch carrier board and a sandwich board

Abstract

The present invention provides a signal connection system between a network switch carrier board and a sandwich board, including a carrier board, a sandwich board, a first connector and a second connector, wherein the carrier board and the sandwich board are connected by the The first connector is connected to the second connector; 4 3.3V power supply pins and 8 5V power supply pins are defined on the carrier board; the size of the sandwich board is 150mm*100mm; the first connection The connector and the second connector have the same structure. The signal connection system between the network switch carrier board and the interlayer board of the present invention overcomes the defect that the XMC interlayer board cannot meet the heat dissipation requirements; solves the problem of insufficient power supply of the single-width XMC interlayer board; also solves the problem that the area of ​​the single-width XMC interlayer board is too large Small, unable to place the problem of the device.

Description

technical field [0001] The invention relates to a signal connection method, in particular to a signal connection system between a network switch carrier board and a sandwich board. Background technique [0002] In the prior art, computer motherboards all adopt a modular design, and are generally divided into a processor part and a peripheral interface part in terms of functions. For the convenience of configuration, maintenance and cost saving, the processor part and the peripheral interface part are usually designed separately, and the functions of the whole machine are realized through the interconnection of two boards. Usually, the processor part is implemented by a mezzanine board, and the peripheral interface part is implemented by a carrier board. [0003] At present, in the field of industrial control computers and consumer computers, the connection between the carrier board and the sandwich board generally adopts the golden finger connection method or the XMC standa...

AI Technical Summary

Problems solved by technology

[0006] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a signal connection system between the network switch carrier board and the interlayer board, which overcomes the shortcoming that the golden finger cannot be used in a vibration environment, and also solves the problem of the XMC standard Issues where flexible configuration is not possible due to fixed size and current requirements
