Technical field
The utility model relates to a kind of pluggable light transceiving module.
Background technology
Along with the quickening of the transmission speed of optical transceiver module and a kind of obstacle that runs into more and more relates to electromagnetic interference (EMI) or EMI (Electromagnetic Interference).EMI is the electrical noise by the parts generation of optical transceiver module, with the electromagnetic wave form performance of module emission.
The encapsulation of optical transceiver module especially especially easily produces electromagnetic interference (EMI) EMI with the optical transceiver module encapsulation of high transmission speed work.This phenomenon is undesirable, and this is can disturb the normal operation of other electron component due to EMI.Especially its physical configuration is suppressing to do relatively poorly aspect EMI when the optical transceiver module formation speed increases.Some zones of optical transceiver module as circular arc exterior contour joint fitting surface each other between the joint between module base and upper cover and coaxial optical and module base all more easily produce electromagnetic interference (EMI) than other zone.
The effective method that solves the EMI radiation is electromagnetic screen.Electromagnetic screen is to utilize shield to produce attenuation to electromagnetic wave, avoids electromagnetic causing to disturb or injury thereby reduce.Material as shielding is divided into high conductivity material and high-permeability material.Wherein conductive material is that shielding principle is to utilize it will produce larger induction current under electromagnetic effect, these electric currents will weaken electromagnetic passing through according to Lenz law, and the frequency electromagnetic waves that the element of shielding case inside or equipment produce is unlikely to affect external unit or human-body safety.
Electromagnetic screen for conductor material, realize it being that effect is best with the metal shell of integral body, but in practical application, need owing to designing and assembling, between module base and upper cover, optical assembly adapter shell and base, the conduction tie point is few, can greatly affect the effectiveness of whole optical module.
Summary of the invention
For overcoming above shortcoming, the utility model provides a kind of many pluggable light transceiving modules of tie point that conduct electricity, and its EMI shield effectiveness is good.
For reaching above goal of the invention, the utility model provides a kind of pluggable light transceiving module, comprise: a base and a upper cover, be provided with a utilizing emitted light assembly, in base and receive optical assembly, surrounding also is provided with an electromagnetic screen pad between described base and upper cover composition surface, this pad edge is provided with a plurality of elasticity gear pieces, form conduction after this elasticity gear piece part contact and the edge contact of described upper cover and be connected, another part contact with after described base edge contacts also formation conduct electricity and be connected.
Also be respectively equipped with an electromagnetic screen ring on described utilizing emitted light assembly and reception optical assembly two adapters.
The outer shroud of described electromagnetic screen ring or interior ring edge are provided with a plurality of elasticity gear pieces, this elasticity gear piece part contact is with described utilizing emitted light assembly and form conduction after being connected optical assembly two adapter shells contacts and be connected, another part contact with after base contacts also formation conduct electricity and be connected.
Described elasticity gear piece is the waveform gear piece that positive and negative are equipped with projection.
Described elasticity gear piece is that the T font reverses gear piece.
Described elasticity gear piece is the staggered gear piece that stretches to both sides.
The pluggable light transceiving module of said structure is because composition surface surrounding between base and upper cover is provided with an electromagnetic screen pad.In addition, also be respectively equipped with an electromagnetic screen ring on utilizing emitted light assembly and reception optical assembly two adapters, no matter be electromagnetic screen pad or ring shielding magnetism, its material is conductive material, and be equipped with the elasticity gear piece of a plurality of contacts, these contacts can guarantee between base and upper cover, component adapter shell and base that all conduction is connected, and can improve like this effectiveness of whole optical module.
