Electromagnetic shielding device

Abstract

An electromagnetic shielding device suitable for a PCB includes a cover and a conductive rubber frame. The cover is made of a conductive material and has a through hole and a containing space. The conductive rubber frame is contacted with the through hole of the cover. The conductive rubber frame contacts with the PCB and is electrically connected to the ground end. The electronic component is enclosed by the cover and the conductive rubber frame.

1 . An electromagnetic shielding device, suitable for a PCB comprising an electronic component disposed thereon and a ground end, the electromagnetic shielding comprising:
 a cover made of a conductive material, the cover having a through hole and a containing space; and   a conductive rubber frame contacted with the through hole of the cover, wherein the conductive rubber frame contacts with the PCB and is electrically connected to the ground end, and the electronic component is enclosed by the cover and the conductive rubber frame.   
   
   
       2 . The electromagnetic shielding device as recited in  claim 1 , wherein the conductive material is metal. 
   
   
       3 . The electromagnetic shielding device as recited in  claim 1 , wherein the cover comprises a cover plate and a side wall joining the cover plate, while the through hole is formed in the side wall. 
   
   
       4 . The electromagnetic shielding device as recited in  claim 3 , wherein the conductive rubber frame comprises:
 a sheath portion, enclosing the side wall; and   at least a plug portion, located in the through hole, wherein both ends of the plug portion join with the sheath portion.   
   
   
       5 . The electromagnetic shielding device as recited in  claim 1 , wherein the conductive rubber frame comprises at least a positioning portion extending towards the PCB, the PCB has a positioning hole corresponding to the positioning portion, the positioning portion is disposed in the positioning hole, so as to position the cover and the conductive rubber frame on the PCB.
