Definitions
- the invention relates to a shielding housing for electrically shielding one or more components on a printed circuit board as well as to a method of producing such a shielding housing.
- soldered shielding cans or housings are used to shield critical components on a printed circuit board.
- the shielding cans are soldered to conductors on the printed circuit board to cover the critical components.
- Shielding cans soldered to printed circuit boards are difficult to remove and replace in connection with such tests and services.
- the object of the invention is to bring about a shielding housing which is easy to mount and dismount, and which is inexpensive to produce and inexpensive to replace.
- the shielding housing in accordance with the invention is made of an inexpensive non-shielding material or semi-shielding/semi-conducting material, e.g. a plastic material, with or without conductive fillers such as graphite and metal fibers, and has at least one cavity for receiving the components to be shielded.
- an elastic gasket is provided along the rim of the cavity.
- the gasket as well as the inner and/or outer surface of the housing is covered by an electrically shielding material, e.g. a conductive paint, a metallization or a metal foil.
- the shielding housing according to the invention is intended to be pressed, i.e. not soldered, with its gasket against a conductor which is provided around the components to be shielded.
- the shielding housing will be easy to mount and dismount. Since the shielding housing according to the invention is made of inexpensive material, it is inexpensive to produce.
- FIGS. 1 - 5 are schematical cross-sectional views of five different embodiments of a shielding housing according to the invention.
- Fig. 1 shows a first embodiment of a shielding housing in accordance with the invention, generally denoted 1 1, for shielding one or more components (not shown) on a printed circuit board 12.
- a conductor 13 surrounds the components to be shielded by means of the shielding housing 11.
- the housing 11 as shown on the drawing, comprises a layer 14 of an inexpensive, non-shielding material, e.g. a plastic material, which is somewhat rigid.
- the layer 14 is formed to define a single cavity 15 for receiving the components (not shown) to be shielded on the board 12.
- the gasket 16 may be made of any suitable non-conductive, semi-shielding/semi-conductive or conductive elastic material, e.g. a plastic material such as silicone, silicone rubber, epoxy, polyurethane or thermoplastic elastomeres.
- the gasket 16 may be deposited on the rim of the cavity 15 e.g. by injection moulding, gluing, dispensation or any other suitable process.
- the gasket 16 and the inner surface of the layer 14, i.e. the inside of the cavity 15, are covered by a layer 17 of an electrically shielding material, e.g. a conductive paint, a metallization or a metal foil.
- an electrically shielding material e.g. a conductive paint, a metallization or a metal foil.
- the housing 11 is supposed to be pressed with its gasket 16 against the conductor 13 by means of e.g. at least one screw (not shown) or at least one clip (not shown).
- the housing 11 may be pressed against the printed circuit board by means of e.g. a covering lid (not shown) of the mobile phone.
- Fig. 2 shows a second embodiment of a shielding housing 21 according to the invention.
- the housing 21 according to Fig. 2 comprises a layer 24 of an inexpensive, non-shielding material, which is formed to define a single cavity 25 for receiving the components (not shown) to be shielded on the printed circuit board (not shown in Fig. 2).
- an elastic gasket 26 has been deposited.
- the embodiment according to Fig. 2 differs from the embodiment according to Fig. 1 merely in that the gasket 26 and the outer surface of the layer 24, i.e. the outside of the cavity 25 instead of its inside, are covered by a layer 27 of an electrically shielding material of the same type as in Fig. 1.
- Fig. 3 illustrates a third embodiment of a shielding housing 31 according to the invention.
- the shielding housing 31 resembles the shielding housing 11 in Fig. 1 but is provided with two cavities 35 for shielding two different sets of components (not shown) on a printed circuit board 32.
- the cavities 35 are separated by an elastic partition wall 38 formed from the same material and in the same process as gaskets 36 along the outer rim of the housing 31, i.e. along the rim of a layer 34 of an inexpensive, non-shielding material.
- a layer 37 of a shielding material is deposited on the gasket 36, on the inside of the housing 31, and on the the sides and the lower rim of the partition wall 38.
- the printed circuit board 32 has to be provided with conductors 33 cooperating with not just the gasket 36 but also with the lower rim of the partition wall 38.
- Fig. 4 illustrates a fourth embodiment of a shielding housing 41 according to the invention.
- the embodiment in Fig. 4 resembles the embodiment in Fig. 2, but in accordance with the invention, the housing 41 is provided with a guiding pin 48 which is adapted to cooperate with a corresponding hole 49 in a printed circuit board 42 to fix the location of the housing 41 on the board 42.
- the guiding pin 48 is made intgral with the layer 44 of a non-shielding material in the embodiment illustrated in Fig. 4.
- a layer 47 of a shielding material is deposited on the gasket 46 and the outside of the housing 41.
- Fig. 5 is a fifth embodiment of a shielding housing 51 according to the invention.
- the embodiment in Fig. 5 resembles the embodiment in Fig. 4.
- the only difference between these embodiments is that a layer 57 of shielding material covers a gasket 56 at the rim of the housing 51 as well as both the inside and the outside of the housing 51 and all of a guiding pin 58 cooperating with a corresponding hole 59 in a printed circuit board 52.
- the housing 51 is supposed to be pressed with its gasket 56 against a conductor 53 on the printed circuit board 52.
- the shielding housing according to the invention since the shielding housing according to the invention is not intended to be soldered to a printed circuit board, it will be easy to remove in order to test the components that are located thereunder. After such a test, it will be equally easy to put the shielding housing back in place.
- the shielding housing according to the invention will also be inexpensive to produce. Should the shielding housing have to be replaced, such a replacement will consequently not involve any high costs.
