Shield can of mobile terminal
A shield can of a mobile terminal is provided. The shield can of the mobile terminal includes: at least one shield can installed in a main circuit board of the mobile terminal, and at least one separation wall formed between electronic elements in which electromagnetic interference occurs within the shield can. Hence, shield ability can be improved and simplified manufacturing process of the separation wall can reduce cost.
1. A shield can of a mobile terminal, the shield can comprising:
at least one separation wall formed between electronic elements within the shield can, the electronic elements comprising a plurality of internal electronic elements of the shield can and a plurality of external electronic elements of the shield can,
wherein the shield can is installed in a main circuit board of the mobile terminal so as to have a direct contact with a surface of the main circuit board,
wherein the shield can is formed in a box shape having a hollow inner portion and an opened one surface and can house at least one of the plurality of internal and external electronic elements mounted in an upper surface of the main circuit board, and
wherein one end of the separation wall is soldered to the main circuit board.
2. The shield can of claim 1 , wherein the separation wall includes one or more gaskets separated from one another.
3. The shield can of claim 2 , wherein the one or more gaskets are coupled to one another and are integrally formed.
4. The shield can of claim 3 , wherein the other end of the separation wall is coupled to one surface of the inside of the shield can.
5. The shield can of claim 4 , wherein the gasket is made of a conductive and an elastic material.
6. The shield can of claim 4 , wherein both side surfaces of the integrally formed gasket are coupled to both side surfaces of the inside of the shield can.
7. The shield can of claim 4 , wherein one end of the gasket is fixed using conductive adhesives, whereas the other end of the gasket is coupled to one surface of the inside of the shield can.
8. The shield can of claim 4 , wherein one end of the gasket is mounted in a ground portion, whereas the other end of the gasket is surface-mounted in the main circuit board.
9. The shield can of claim 1 , wherein the shield can is made of a conductive and a hard protective material.
10. The shield can of claim 1 , wherein the internal electronic elements of the shield can cause an abnormal operation when exposed to electromagnetic interference and are at least one of a Radio Frequency (RF) module, a Digital Multimedia Broadcasting (DMB) module, a power amplifier and a low noise amplifier of an RF module, and a television reception chip and a Global Positioning System (GPS) reception chip of a DMB module.
11. The shield can of claim 1 , wherein the external electronic elements of the shield can are at least one of a Liquid Crystal Display (LCD) module, a Central Processing Unit (CPU), and a key input module.
