Abstract
Abstract The invention relates to an EMC enclosure (4) used in radiotelephones as protection of the radiotelephone components, the enclosure (4) having no separate cover in order to service or to repair the components. Between the cover (16) and the side walls (15) the EMC enclosure has necks (7,11) with openings (8,12,13,14) between them. Due to these openings it is possible to open the cover (16) with a suitable tool. When the cover has (16) been opened it is possible to solder it back or to use a repair cover.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
131 words
An electromagnetic compatibility enclosure with side walls (15) and a cover (16) used for providing component protection in an electrical apparatus, characterized in that the side walls (15) and the cover (16) are formed of a same plate preform by bending, and that there is an arrangement in a bending area (3) between the cover (16) and the side walls (15) for opening and closing the enclosure (4), wherein the arrangement on three sides between the cover and the side walls comprises necks (7, 11) and openings (8, 12, 13, 14) between the necks and, at least a part of the openings are made in a U-form (13), so that strips (10) formed thereby can be bent to form brackets for a cable passing along an end of the enclosure (4).
Claim 2
Dependent Claim
131 words
An electromagnetic compatibility enclosure with side walls (15) and a cover (16) used for providing component protection in an electrical apparatus, characterized in that the side walls (15) and the cover (16) are formed of a same plate preform by bending, and that there is an arrangement in a bending area (3) between the cover (16) and the side walls (15) for opening and closing the enclosure (4), wherein the arrangement on three sides between the cover and the side walls comprises necks (7, 11) and openings (8, 12, 13, 14) between the necks and, at least a part of the openings are made in a U-form (13), so that strips (10) formed thereby can be bent to form brackets for a cable passing along an end of the enclosure (4).
Claim 3
Dependent Claim
46 words
An electromagnetic compatibility enclosure as claimed in claim 1, wherein the cover of the electromagnetic compatibility enclosure (4) can be opened when the necks (7, 11) on three sides are cut off, whereby the edge between the cover and a fourth side acts as a hinge.
Claim 4
Dependent Claim
36 words
An electromagnetic compatibility enclosure as claimed in claim 1, wherein the arrangement on a fourth side between the cover and the side walls comprises necks (7, 11) and openings (8, 12, 13, 14) between the necks.
Claim 5
Dependent Claim
40 words
An electromagnetic compatibility enclosure as claimed in claim 1, wherein there are adjustment trimmer holes (9) in the cover for inserting an adjustment spanner through the holes (9) to adjust trimmers of a component enclosed by the electromagnetic compatibility enclosure.
Claim 6
Dependent Claim
27 words
An electromagnetic compatibility enclosure as claimed in claim 1, wherein teeth (5) extend from a lower edge of the side walls in the direction of the walls.
Claim 7
Dependent Claim
44 words
An electromagnetic compatibility enclosure as claimed in claim 5, wherein the teeth (5) have shoulders (6), wherein the teeth can be cut off at the shoulders (6) for fastening the shoulders as surface mount contacts to a circuit board with the aid of solder.
Claim 8
Dependent Claim
77 words
An electromagnetic compatibility enclosure comprising a frame (1) having a general U-shaped aperture (13) extending therethrough, the aperture (13) defining a strip (10) of the frame (1) that is deformable for retaining a cable on the frame (1) wherein the frame (1) includes side walls (15) and a cover (16), the frame (1) having necks (7, 11) and openings (8,12, 14) between the necks at a junction (3) between the side walls (15) and the cover (16).
Claim 9
Dependent Claim
77 words
An electromagnetic compatibility enclosure comprising a frame (1) having a general U-shaped aperture (13) extending therethrough, the aperture (13) defining a strip (10) of the frame (1) that is deformable for retaining a cable on the frame (1) wherein the frame (1) includes side walls (15) and a cover (16), the frame (1) having necks (7, 11) and openings (8,12, 14) between the necks at a junction (3) between the side walls (15) and the cover (16).
Claim 10
Dependent Claim
29 words
An electromagnetic compatibility enclosure as in claim 7 wherein the frame (1) has a plurality of the general U-shaped apertures (13) on different walls (15) of the frame (1).
Claim 11
Dependent Claim
33 words
An electromagnetic compatibility enclosure as in claim 7 wherein the frame (1) is comprised of a one-piece metal preform made from a metal plate that is cut and deformed to form the enclosure.
Claim 12
Dependent Claim
28 words
An electromagnetic compatibility enclosure as in claim 7 wherein the frame (1) includes teeth (5) extending from a lower edge of side walls (15) of the frame (1).
Claim 13
Dependent Claim
39 words
An electromagnetic compatibility enclosure as in claim 10 wherein the frame (1) includes shoulders (6) at bases of the teeth (5), wherein the teeth (5) can be removed for surface mounting the shoulders (6) onto a printed circuit board.
