Abstract
Abstract A structure for covering a gap in a joint, which is between a pair of wall members which are interconnected by threaded fasteners such as bolts, of an electromagnetic screening enclosure and for electrically interconnecting the pair of wall members characterized by a metal cover member. Preferably, the wall members each have a pair of oppositely facing flanges which are adjacent to the gap of the joint and the cover member may be either a resilient member having edge portions for engaging the edges of the adjacent flanges for forming electrical connections therebetween, may be rigid and the structure includes either resilient or mechanical members for holding or clamping the edge portion in electrical engagement with the flanges of the wall members, or may be a flat sheet attached to each of the flanges of the wall members by an electrically conductive adhesive.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
163 words
A structure sealing a joint in an electro-magnetic screening enclosure, the joint being between a pair of wall members with each member having a first flange extending the length of the member and at an angle to said member, each of said first flanges terminating in a second flange extending at an angle to said first flange and having a free edge, said members being held together by threaded fasteners with said first flanges of the members being in facing relationship and said second flanges being adjacent each other and on opposite sides of the residual gap of the joint with their free edges facing in opposite directions, said structure comprising an electrically conductive cover member of a resilient metal, said cover member having a pair of spaced portions and being detachably mounted on said wall members with the spaced portions of the cover member engaging the free edges of the adjacent second flanges, electrically interconnecting the wall members and covering the gap.
Claim 2
Dependent Claim
163 words
A structure sealing a joint in an electro-magnetic screening enclosure, the joint being between a pair of wall members with each member having a first flange extending the length of the member and at an angle to said member, each of said first flanges terminating in a second flange extending at an angle to said first flange and having a free edge, said members being held together by threaded fasteners with said first flanges of the members being in facing relationship and said second flanges being adjacent each other and on opposite sides of the residual gap of the joint with their free edges facing in opposite directions, said structure comprising an electrically conductive cover member of a resilient metal, said cover member having a pair of spaced portions and being detachably mounted on said wall members with the spaced portions of the cover member engaging the free edges of the adjacent second flanges, electrically interconnecting the wall members and covering the gap.
Claim 3
Dependent Claim
27 words
A structure according to claim 1, wherein the cover member has a helmut-shaped cross section with said spaced portions resiliently engaging edges of the adjacent second flanges.
Claim 4
Dependent Claim
46 words
A structure according to claim 1, wherein the cover member has a V-shaped cross section having a pair of legs interconnecting the spaced portions, said legs resiliently urging the spaced portions into engagement with the free edges of the adjacent second flanges of the wall members.
Claim 5
Dependent Claim
18 words
A structure according to claim 3, wherein said spaced portions are parallel portions and terminate in diverging portions.
Claim 6
Dependent Claim
15 words
A structure according to claim 3, wherein said portions are inwardly directed edge spaced portions.
Claim 7
Dependent Claim
22 words
A structure according to claim 1, wherein the pair of spaced portions are curved portions interconnected by a convex cross sectional portion.
Claim 8
Dependent Claim
17 words
A structure according to claim 1, wherein the cover member is made of a magnetically conductive material.
