Method for setting ground system in complete machine of LTE communication product

Abstract

The invention provides a method for setting a ground system in a complete machine of an LTE communication product. The method comprises the steps that: a ground signal of the complete machine is set, a backboard in the complete machine is fixed on a chassis of the complete machine through screws, and a ground copper band is designed on a printed circuit board; a backboard and other veneers are connected with a digital connector and a power connector through a positioning guide pin, and the pin lengths are sequenced from large to small as follows: the positioning guide pin, the digital connector and the power connector; the sidebands of the veneers are divided into different segments; and when the power connector and the digital connector on the backboard are selected, and the lengths of the signal pins on the power connector and the digital connector are sequenced from large to small as follows: a ground pin and other network pins. During hot plug of the veneers, it is guaranteed that a ground signal is preferably contacted than a digital signal. The method provided by the invention is used for sequentially processing various different ground plans in the complete machine system in combination with grounding, so that the complete machine has better EMC properties.

Description

technical field [0001] The present invention relates to the technical field of LTE communication equipment, and in particular to a method for setting up a grounding system in a whole machine of an LTE communication product, including a processing method for hot plugging of a single board in the whole machine and chassis grounding. Background technique [0002] Communication equipment in the communication industry needs to pass the corresponding safety certification before it can be sold in the market. Repeaters, base stations, and LTE equipment are all communication equipment, and the safety standard that needs to be implemented is GB4943 (information technology category). China Compulsory Certification is referred to as CCC (China Compulsory Certification) certification or 3C certification. The grounding resistance involved in the 3C certification and the product test items in abnormal use environments are all necessary items for safety testing, ensuring that consumers wil...

AI Technical Summary

Problems solved by technology

[0003] Due to the imperfect handling of the ground in the hardware design of traditional communication equipment, when the single board in the whole machine is hot-swapped, there will be static electricity accumulated on the single board or the chassis, and the discharge electric shock will occur to the operator.

Not only the product cannot pass the safety certification, but it will also cause certain harm to the operators of the laboratory
