Abstract
The invention provides a pluggable optical transceiver module, which comprises a base and an upper cover, wherein a light emitting assembly and a light receiving assembly are arranged in the base; an electromagnetic shielding gasket is also arranged on the periphery between the faying surfaces of the base and the upper cover; the surrounding edge of the gasket is provided with a plurality of elastic tooth sheets; one part of contacts of the elastic tooth sheets is formed into electric conduction connection after making contact with the surrounding edge of the upper cover; the other part of contacts is also formed into conduction connection after making contact with the surrounding edge of the base. Therefore, the contact points of the base and the upper cover are increased, a plurality of electric conduction connection points are formed, and therefore, the electromagnetic shielding effect is improved.
Description
Technical field
The present invention 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 running into more and more relates to electromagnetic interference (EMI) or EMI (Electromagnetic Interference).EMI is the electrical noise being produced by the parts of optical transceiver module, with the electromagnetic wave form performance of module transmitting.
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 the normal operation that can disturb other electron component due to EMI.Especially in the time that optical transceiver module formation speed increases, its physical configuration is suppressing to do poorly aspect EMI.Some regions of optical transceiver module as between the joint between module base and upper cover and coaxial optical and module base each other circular arc exterior contour engage fitting surface, all more easily produce electromagnetic interference (EMI) than other region.
The effective method that solves 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 under electromagnetic effect, will to produce larger induction current, 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.
For the electromagnetic screen of conductor material, realizing with overall metal shell is that effect is best, but in practical application, need owing to designing and assembling, the tie point that conducts electricity between module base and upper cover, optical assembly adapter shell and base is few, can greatly affect the effectiveness of whole optical module.
Summary of the invention
For overcoming above shortcoming, the invention provides a kind of many pluggable light transceiving modules of tie point that conduct electricity, its EMI shield effectiveness is good.
For reaching above goal of the invention, the invention provides a kind of pluggable light transceiving module, comprise: a base and a upper cover, in base, be provided with a utilizing emitted light assembly, and receive optical assembly, between described base and upper cover composition surface, surrounding is also provided with an electromagnetic screen pad, this pad edge is provided with multiple elasticity gear pieces, after this elasticity gear piece part contact contacts with described upper cover edge, form conduction and be connected, another part contact is connected with also formation conduction after the contact of described base edge.
On described utilizing emitted light assembly and reception optical assembly two adapters, be also respectively equipped with an electromagnetic screen ring.
The outer shroud of described electromagnetic screen ring or interior ring edge are provided with multiple elasticity gear pieces, this elasticity gear piece part contact forms conduction after contacting with reception optical assembly two adapter shells with described utilizing emitted light assembly and is connected, and another part contact is connected with also formation conduction after base contact.
Described elasticity gear piece is that positive and negative are equipped with protruding waveform gear piece.
Described elasticity gear piece is that 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, because composition surface surrounding between base and upper cover is provided with an electromagnetic screen pad.In addition, on utilizing emitted light assembly and reception optical assembly two adapters, be also respectively equipped with an electromagnetic screen ring, no matter be electromagnetic screen pad or ring shielding magnetism, its material is conductive material, and be equipped with the elasticity gear piece of multiple 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.
