Abstract
Abstract An enclosure for an electrical terminal block includes a housing having a back wall and projecting side walls extending thereabout to form a bounded chamber. One side wall includes an opening formed therethrough for permitting passage of an electrical cable into the bounded chamber. A barrier member is supported by the side wall adjacent the opening. The barrier member includes a barrier wall at least partially surrounding the opening about a periphery thereof. The barrier member includes a pair of elongate oppositely directed deflectable fingers projecting inwardly from the barrier wall. Distal ends of the oppositely directed fingers overlap to close-off the opening.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
138 words
An enclosure for an electrical terminal block and electrical cables terminated to said terminal block, said enclosure comprising: a housing having a back wall and a side wall projecting therefrom and extending thereabout to form a bounded chamber interiorly thereof, said terminal block being supported within said chamber; said side wall including an opening formed therethrough for permitting passage of an electrical cable into said bounded chamber; barrier means supported by said side wall adjacent said opening, said barrier means including a barrier wall at least partially surrounding said opening about a periphery thereof and a pair of elongate oppositely directed deflectable fingers projecting inwardly from said barrier wall into said opening, distal ends of said oppositely directed fingers overlapping to close-off said opening; and a cover movably supported by said side wall for enclosing said terminal block.
Claim 2
Dependent Claim
138 words
An enclosure for an electrical terminal block and electrical cables terminated to said terminal block, said enclosure comprising: a housing having a back wall and a side wall projecting therefrom and extending thereabout to form a bounded chamber interiorly thereof, said terminal block being supported within said chamber; said side wall including an opening formed therethrough for permitting passage of an electrical cable into said bounded chamber; barrier means supported by said side wall adjacent said opening, said barrier means including a barrier wall at least partially surrounding said opening about a periphery thereof and a pair of elongate oppositely directed deflectable fingers projecting inwardly from said barrier wall into said opening, distal ends of said oppositely directed fingers overlapping to close-off said opening; and a cover movably supported by said side wall for enclosing said terminal block.
Claim 3
Dependent Claim
17 words

Claim 4
Dependent Claim
52 words
An enclosure in accordance with claim 1 wherein said barrier means includes an additional deflectable finger extending from said barrier wall vertically spaced from and substantially parallel to one finger of said pair, said additional deflectable finger having a distal end overlapping said distal end of the other finger of said pair.
Claim 5
Dependent Claim
23 words
An enclosure in accordance with claim 1 wherein said barrier means includes a puncturable membrane spanning said opening to additionally close-off said opening.
Claim 6
Dependent Claim
20 words
An enclosure in accordance with claim 4 wherein said membrane is puncturable upon said passage of said electrical cable therethrough.
Claim 7
Dependent Claim
31 words
An enclosure in accordance with claim 1 wherein said opening formed through said side wall is an elongate slot having a transverse extent defined by spaced apart longitudinal slot side edges.
Claim 8
Dependent Claim
36 words
An enclosure in accordance with claim 6 wherein said barrier wall extends along said slot side edges, said pair of deflectable fingers extending along the longitudinal extent of said slot to close-off said slot transverse extent.
Claim 9
Dependent Claim
50 words
An enclosure in accordance with claim 7 wherein said barrier means includes an additional deflectable finger extending from said barrier wall spaced from and substantially parallel to one finger of said pair, said additional finger having a distal end overlapping said distal end of the other finger of said pair.
Claim 10
Dependent Claim
34 words
An enclosure in accordance with claim 7 wherein said barrier means includes a puncturable membrane spanning said traverse extent of said slot, said membrane being puncturable upon insertion of said cable in said slot.
Claim 11
Dependent Claim
16 words

Claim 12
Dependent Claim
103 words
An electrical enclosure comprising: a box including a back wall, side walls and an cover defining a chamber therein for supporting an electrical terminal device; a plurality of longitudinal cable entry slots spaced along one of said side walls for providing passage for plural electrical cables, each of said slots having a longitudinal extent extending along a longitudinal center line and a transverse extent; and barrier means covering said cable entry slots, said barrier means including a barrier finger extending transversely from each longitudinal side of each said slot, each of said fingers extending beyond the longitudinal center line of each said slot.
Claim 13
Dependent Claim
103 words
An electrical enclosure comprising: a box including a back wall, side walls and an cover defining a chamber therein for supporting an electrical terminal device; a plurality of longitudinal cable entry slots spaced along one of said side walls for providing passage for plural electrical cables, each of said slots having a longitudinal extent extending along a longitudinal center line and a transverse extent; and barrier means covering said cable entry slots, said barrier means including a barrier finger extending transversely from each longitudinal side of each said slot, each of said fingers extending beyond the longitudinal center line of each said slot.
Claim 14
Dependent Claim
36 words
