Abstract
An EMI shield is used for shielding electronic components on a printed circuit board of a mobile phone. The shield comprises a cover and a pair of grounding strips, all being made by conductive material. The pair of grounding strips is soldered on the printed circuit board. A plurality of latches is formed on each grounding strip. The cover, which is substantially in the shape of an inverted U, comprises a shielding plate and a pair of rims depending downward from opposite sides of the shielding plate. A plurality of openings defined in the rims engages with respective latches of the grounding strips to secure the cover to the printed circuit board.
Claims5
A shield device for shielding electronic components mounted on a printed circuit board, comprising:
- a pair of grounding strips being secured to a printed circuit board;
- a conductive cover shielding electronic components provided on the circuit board, the conductive cover having a shielding plate and a pair of rims depending downward from the shielding plate;
- and
- means for releasably engaging the rims of the conductive cover with the grounding strips, wherein the means for releasably engaging includes a latch formed on each grounding strip and an opening defined in each rim of the conductive cover for receiving the latch.
A mobile phone comprising:
- a printed circuit board with a plurality of electronic components mounted thereon;
- a pair of strips securely attached unto the printed circuit board by two sides of said electronic components;
- a conductive cover including an electrically shielding plate and a pair of downwardly extending rims on two sides of said electrically shielding plate, a transverse dimension of said electrically shielding plate being compliant with a distance between the pair of strips wherein said cover is detachably engaged with the corresponding pair of strips, respectively, and the cover electrically shields the electronic components under the electrically shielding plate thereof.
