In description of the present utility model, except as otherwise noted, the implication of " multiple " is two or more.
Fig. 3 to Fig. 7 is a specific embodiment of the utility model embodiment pluggable optical module, and the pluggable optical module in the present embodiment, comprises housing 1, and is connected to the emi shield clip 2 on housing 1; Electric-conductor 3 is provided with between housing 1 and emi shield clip 2; When described pluggable optical module inserts optical module cage 4, electric-conductor 3 can block the gap 5 between housing 1 and emi shield clip 2.
Described electric-conductor 3 is conductive parts, and example, can be conductive mesh, conducting foam or conductive rubber etc., the utility model embodiment limit this.
The pluggable optical module that the utility model embodiment provides, owing to being provided with electric-conductor 3 between housing 1 and emi shield clip 2, when described pluggable optical module inserts optical module cage 4, electric-conductor 3 can block the gap 5 between housing 1 and emi shield clip 2, thus prevent the electromagnetic wave in optical module cage 4 to reveal from the gap 5 between emi shield clip 2 and housing 1, and then decrease electromagenetic wave radiation, also just avoid and interference is caused to other electronic equipment neighbouring.
Preferably, described electric-conductor 3 has elasticity, and namely electric conductor 3 is squeezed deformable.What electric-conductor 3 can be arranged like this is thicker, and when emi shield clip 2 is connected on housing 1, emi shield clip 2 can extrude electric-conductor 3, makes electric-conductor 3 block the better effects if in gap between housing 1 and emi shield clip 2.In addition, electric-conductor 3 has certain elasticity and can make that emi shield clip 2 is easier to be connected on housing 1.
In order to avoid electric-conductor 3 hinders described pluggable optical module insert optical module cage 4 or extract in optical module cage 4, with reference to Fig. 3 and Fig. 4, emi shield clip 2 in the present embodiment covers electric-conductor 3, thus, can prevent the local of electric-conductor 3 from exposing between housing 1 and emi shield clip 2, and then the exposed portion avoiding electric-conductor 3 is inserted optical module cage 4 or is extracted in optical module cage 4 and cause obstruction to described pluggable optical module.
Concrete, with reference to Fig. 8, emi shield clip 2 comprises C shape sheet metal 21, and is fixed on the multiple metal clips 22 on C shape sheet metal 21 1 side, and multiple metal clips 22 is evenly arranged.When described pluggable optical module inserts optical module cage 4, C shape sheet metal 21 first enters in optical module cage 4 by the opening of optical module cage 4, then multiple metal clips 22 arrives the opening part of optical module cage 4, now multiple metal clips 22 is subject to the extruding generation elastic deformation of optical module cage 4 inside surface, thus by the space shutoff between housing 1 and optical module cage 4, prevent the electromagnetic wave in optical module cage 4 from revealing between housing 1 and optical module cage 4.
The length of electric-conductor 3 can be greater than, be less than or equal to the length of run of C shape sheet metal 21, when the length of electric-conductor 3 is greater than the length of run of C shape sheet metal 21, the local of electric-conductor 3 is easily exposed between housing 1 and emi shield clip 2, affect the insertion of pluggable optical module and extract, the cost of pluggable optical module also can be caused to increase, in order to avoid the problems referred to above, the length of the electric-conductor 3 in the present embodiment is less than or equal to the length of run of C shape sheet metal 21, thus, can electric-conductor 3 be arranged between emi shield clip 2 and housing 1 completely, avoid impacting the insertion of pluggable optical module and extracting, also save cost simultaneously.
On the basis of above-described embodiment, in the present embodiment, the length of preferred electric-conductor 3 equals the length of run of C shape sheet metal 21, thus, not only can save cost, also the gap 5 between emi shield clip 2 and housing 1 can be blocked completely by electric-conductor 3, prevent electromagnetic wave leakage.
In order to prevent the electromagnetic wave leakage in optical module cage 4, save cost simultaneously, the width of the electric-conductor 3 in the present embodiment is less than or equal to the length of metal clips 22, now, can electric-conductor 3 be arranged between metal clips 22 and housing 1, because metal clips 22 is connected in the opening part of optical module cage 4 usually, therefore, electric-conductor 3 is arranged between metal clips 22 and housing 1, can prevent the electromagnetic wave in optical module cage 4 from revealing from the opening part of optical module cage 4, also reduce cost simultaneously.
Thickness after electric-conductor 3 in the present embodiment is squeezed is less than or equal to multiple metal clips 22 to the minor increment in the distance of housing 1, after can ensureing to be provided with electric-conductor 3 like this on housing 1, emi shield clip 2 can also be connected on housing 1 smoothly, ensures that the described pluggable optical module being connected with emi shield clip 2 can insert optical module cage 4 smoothly simultaneously.
In a kind of embodiment of the present utility model, electric-conductor 3 is conductive mesh, described conductive mesh can be the net made by electric conductor, also can be the net that electric conductor and electrical insulator mix, the utility model embodiment does not limit this, the conducting electricity very well of conductive mesh, shielding properties are high, can improve shielding electromagnetic waves effect in optical module cage 4.
In another kind of embodiment of the present utility model, electric-conductor 3 is the good springiness of conducting foam, conducting foam, when installing conducting foam on housing 1, when installing emi shield clip 2 again, the compression degree of conducting foam is large, thus avoids and bring inconvenience to the installation of emi shield clip 2.
In the third embodiment of the present utility model, electric-conductor 3 is conductive rubber, and conductive rubber not only conducts electricity very well, shielding properties is high, and ageing-resistant, easy-formation, stability are better, can extend the serviceable life of described pluggable optical module.
Further, electric-conductor 3 is bonding with housing 1 by conducting resinl, and conducting resinl not only has good electric conductivity, can also connect similar or inhomogeneous various material, few to the restriction of material, and adhesive property is good, more convenient operation, can simplified processing process.
