Abstract
Provided by the utility model is an anti-electromagnetic interference SFP light transmit-receive module. The surface of a module base is provided with a sleeve assembling area; the front end of the assembling area is provided with a first groove; a first elastic conductor is fixed in the groove; the opening of a cage forms conductive connection with the surface of the module base; the sleeve assembling area also comprises a second groove; a second elastic conductor is fixed in the second groove; and the inner wall of the cage forms conductive connection with the surface of the module base. According to the anti-electromagnetic interference SFP light transmit-receive module, since the front end of the sleeve assembling area on the surface of the module base is provided with the first elastic conductor, the opening edge and the inner wall of the cage and the surface of the module base can form quite good conductive contact, and if for further increasing conductive contact points, the second elastic conductor can also be arranged at other positions in the sleeve assembling area on the surface of the base, such that the inner wall of the cage forms conductive connection with the surface of the module base through the second elastic conductor.
Description
Technical field
The utility model relates to a kind of SFP(Small Form Factor Pluggable) optical transceiver module, relate in particular to a kind of SFP optical transceiver module of anti-electromagnetic interference.
Background technology
Along with the transmission rate of SFP or SFP+ optical transceiver module increases, can face the problem of electromagnetic interference EMI (Electromagnetic Interference, hereinafter to be referred as EMI).EMI is the electrical noise being produced by the electronic component of optical transceiver module inside, with the form performance of module emitting electromagnetic wave.The encapsulation of optical transceiver module especially especially easily produces electromagnetic interference with the encapsulation of the optical transceiver module of two-forty work, because EMI can disturb the normal operation of other electron component, although in system host frame for metal cage (Cage) ground connection of installation module, but, when optical transceiver module inserts after cage, although have vest between module metab and metal cage as conduction intermediary, owing to there being some local small gap, base and cage can not form good conduction link circuit, cause optical transceiver module earthing effect poor, cannot shield electromagnetic interference.
Summary of the invention
For overcoming above shortcoming, the utility model provides a kind of SFP optical transceiver module of anti-electromagnetic interference.
The utility model provides a kind of SFP optical transceiver module of anti-electromagnetic interference, module base surface is provided with vest assembly section, this assembly section front end is provided with the first groove, fixes the first elastic electric conductor in this groove, and the opening of cage forms conduction by this elastic electric conductor with module base surface and is connected.
Described vest assembly section also comprises the second groove, fixes the second elastic electric conductor in this groove, and the inwall of cage forms conduction by this second elastic electric conductor with module base surface and is connected.
Described first, second elastic electric conductor is conductive rubber strip.
Described first, second elastic electric conductor center is implanted into a shaping steel wire.
Described first, second elastic electric conductor is conductive rubber slice.
Due to the SFP optical transceiver module of the anti-electromagnetic interference of said structure, because the vest assembly section front end on module base surface is provided with the first elastic electric conductor, make the edge of opening of cage and inwall and module base surface all can form good conductive contact, if in order further to increase conductive contact point, can also the second elastic electric conductor be set at other position, vest assembly section of susceptor surface, like this, the inwall of cage forms to conduct electricity with module base surface by this second elastic electric conductor and is connected.

Embodiment
Describe the utility model most preferred embodiment in detail below in conjunction with accompanying drawing.
The SFP optical transceiver module 100 of anti-electromagnetic interference as shown in Figure 1, module base surface is provided with vest assembly section 10, this assembly section front end is provided with the first groove 20, fixing the first elastic electric conductor 40 as shown in Figure 2 in this groove, the opening 210 of cage 200 as shown in Figure 4 forms conduction by this elastic electric conductor with module base surface and is connected, module is inserted after cage, due to the resilient force of the first elastic electric conductor 40, can ensure that cage opening 210 edges and inwall all can keep fully contacting with module base surface, making cage opening 210 form conduction preferably by this elastic electric conductor and module base surface is connected.
In order further to improve better the effectiveness of module, vest assembly section 10 also comprises the second groove 30, fixing the second elastic electric conductor 50 as shown in Figure 3 in this groove, module is inserted after cage, and the inwall 220 of cage 200 forms conduction by this second elastic electric conductor 50 with module base surface and is connected.Above-mentioned first, second elastic electric conductor 40,50 is conductive rubber strip or conductive rubber slice, and conductive rubber strip center can also be implanted into a shaping steel wire, makes to be fixed in groove after conductive rubber strip moulding.
First, second elastic electric conductor 40,50 that the vest assembly section, module base surface 10 of said structure arranges, its object is all the conduction tie points in order to increase cage 200 and module base surface, improves the anti-electromagnetic interference effect of module.
