Abstract
The utility model provides an anti-electromagnetic interference light transceiver module. The module comprises a module metal housing. At least a spring is fixed to the EMI grounding elastic area of the module metal housing. One spring is provided. An elastic forming strip is inserted into the center of the spring. A vest is further fixed in the EMI grounding elastic area. The two ends of the spring are connected to the vest. Since the EMI grounding elastic area of the module metal housing is provided with the spring, the inner surface of a cabinet chamber and the surface of the module metal housing form a plurality of conductive connecting loops through springs, so that anti-electromagnetic interference shielding effects of the module is effectively improved.
Description
Technical field
The utility model relates to a kind of optical transceiver module of hot plug, relates in particular to a kind of optical transceiver module of anti-electromagnetic interference.
Background technology
Along with the transmission rate of optical transceiver module increases, can face the unfailing performance problem of anti-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, in the time that pluggable light transceiving module inserts cage work, between module metal shell surface and metal cage inner surface, may can not form conduction link circuit in some small gap, cause optical transceiver module there is no ground connection, cannot shield electromagnetic interference.
Summary of the invention
For overcoming above shortcoming, the utility model provides a kind of optical transceiver module of anti-electromagnetic interference simple in structure.
The utility model provides a kind of optical transceiver module of anti-electromagnetic interference, comprises a module metal shell, and the EMI ground connection Hookean region that is positioned at described module metal shell is at least fixed a spring.
Described spring is one.
Described spring center inserts an elastic forming bar.
Described EMI ground connection Hookean region is also fixed a vest, and described both ends of the spring is connected with vest.
Due to the optical transceiver module of said structure, the EMI ground connection Hookean region of its module metal shell is provided with spring, cabinet cage inner surface and module metal shell surface form multiple conduction link circuits by spring, have effectively improved the electromagnetic interference shield effect of module.

Embodiment
Below in conjunction with accompanying drawing, describe the utility model most preferred embodiment in detail.
The optical transceiver module of the anti-electromagnetic interference of the first embodiment as depicted in figs. 1 and 2, comprising: module metal shell 10, the EMI ground connection Hookean region 11 that is positioned at module metal shell 10 is at least fixed a spring 20.In this example, spring is one, also can many.Spring center also can insert an elastic forming bar 30, as finer wire, inserts in spring 20, is stuck in EMI ground connection Hookean region 11, if there is no moulding bar 30, directly spring 20 two ends is fixed on to EMI ground connection Hookean region 11 surfaces.When spring 20 is with the module insertion machine boxes and baskets period of the day from 11 p.m. to 1 a.m, spring 20 bottoms and module metal shell 10 outer surfaces form conductive contact, spring 20 tops and cabinet cage inner surface form conductive contact, and module metal shell 10 surfaces are realized multipoint mode conduction link circuit with cabinet cage inner surface by spring 20.
The optical transceiver module of the anti-electromagnetic interference of the second embodiment as shown in Figure 3 and Figure 4, different from the first embodiment is, the EMI ground connection Hookean region 11 that is positioned at module metal shell 10 also overlaps and has vest 40, and the two ends of spring 20 are fixed by vest 40, and can not need center to insert elastic forming bar 30.The anti-electromagnetic interference operation principle of spring 20 is identical with the first embodiment.
Claims (4)
