Description
Technical field
The present invention relates to technical field of optical fiber communication, more particularly to a kind of optical module.
Background technology
After optical module product with mainboard in order to realize that reliable signal interaction, optical module are inserted into interface, module machinery knot
Needed on structure ensure module insertion after can steady lock, it is necessary to when extracting again requirement can quick release.Various MSA (QSFP/
QSFP+, SFP/SFP+, CFP/CFP2/CFP4, XFP etc.) both define basic locking hanging point position, as QSFP/QSFP+,
The locking hanging point such as CFP/CFP2/CFP4, XFP is defined on the both sides of module, and the locking hanging point of SFP/SFP+ is defined on module
Bottom.After optical module insertion cabinet, the unlock piece at hanging point is usually unlocked, it is necessary to be connected to the outer of chassis shell by a part
Face, reaches unlock with operating personnel's interaction, this part is slided due to needing relative to light film block module housing, it can not be with
Good conductive optical module housing is integrally formed.
For the consideration of structural strength and fatigue reliability, unlock piece on optical module at least with motherboard cage (metal
Part, edge are sharp) on hook interaction reach unlocking function part need with the big material of intensity such as metal make.
Unlock piece and optical module shell are independent, between need it is opposite slide, need with harder material making, to cause existing again at hook
Most of side unlocked state (such as QSFP, QSFP+, CFP/CFP2/CFP4, XFP) all makes solution using sheet metal component
Latch fitting, after sheet metal component has a unlocking arm, two unlocking arms to stretch out casing respectively in optical module both sides, outside the exposed casing of optical module
Part connected by a beam, tail end by it is encapsulated formation one vertical pulling release handle, or do rotation solution lock machine
Structure.This usual sheet metal part thickness is making, is being easily deformed in assembling process also with regard to 0.5mm or so, distracted if there is having
Situation, this sheet metal component just cannot pass through EMI (electromagnetic interference, the Electromagnetic on mainboard cage
Interference) shrapnel and cabinet, optical module housing are continuously switched on, and the overhanging part of this metal plate unlock piece becomes at this time
One antenna, if the cabinet inside of light film block insertion has EMI to launch restricting the number just, EMI signal be able to can be in by unlock piece
The unlocking arm of cabinet inside is coupled on this part, then is outwards launched by the exposed metal plate part outside cabinet.We
Laboratory observation arrives, and when such case occurs, the module EMI of more than 6dB may be caused to launch increment.
Therefore, the prior art has yet to be improved and developed.
