Housing of transceiver module

Abstract

A transceiver module housing arranged on a circuit board with an opening comprises a housing and at least one first rear housing. The housing includes at least one first screen housing, at least one second screen housing, a spacing plate arranged between the first screen housing and the second screen housing, an upper housing and a lower housing. An outside plate of the upper housing and an inside plate of the lower plate are overlapped with each other to form a housing space for housing the first screen housing and the second screen housing. The rear housing and the housing are fitted with each other to be fixed on the housing. The housing and the rear housing are together installed in the circuit board. The housing is housed in the opening of the circuit board so as to enable the first screen housing and the second screen housing to respectively sleeved at opposite two sides of the circuit board. The rear housing and the second screen housing are located at the same side of the circuit board. The transceiver module housing can effectively use the housing space in a chassis to reduce the whole volume of the chassis.

Description

technical field [0001] The invention relates to a transceiver module casing, in particular to a transceiver module casing capable of shielding electromagnetic interference. Background technique [0002] In the optical communication system, the transceiver module provides bidirectional data transmission between the electrical interface and the optical data link. The transceiver module can receive electrical signals, convert them into corresponding optical signals, and then transmit them in the optical network; meanwhile, the transceiver module can also receive optical signals, convert them into electrical signals, and transmit them to the electrical interface. [0003] In the prior art, the transceiver module is mounted on a printed circuit board of a host computer, an input / output system, a peripheral device or a switch. The transceiver module is plugged into a metal shell mounted on a printed circuit board. The metal shell generally includes two parallel side walls, a rect...

AI Technical Summary

Problems solved by technology

The transceiver module housing 90 of this kind of structure is only located on one side of the circuit board, because a part of space needs to be left between the other side of the circuit board and the adjacent circuit board or the shell, for the normal operation of each component, so the said placement The reserved area will increase the overall design space of the chassis device, which is not conducive to the miniaturization of the entire chassis device
