Abstract

Abstract A housing comprises a generally box-like structure having two end pieces and two elongate members joined thereto. The elongate members each have stiffening ribs or cavities and comprise at least one section cut from an extruded bar of indefinite length, thereby affording the advantage that housings of any desired size can be produced from profiled bars of infinite length.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 242 words
A housing construction for electrical components comprising (A) two spaced, opposed, flattened side wall members; (B) two spaced, opposed, flattened end wall members; (C) each one of said side wall and end wall members being an extruded profile comprised of an aluminum alloy; (D) each one of said side wall members being further characterized by having integrally defined therein a plurality of spaced, parallel channel members which extend through and thereacross, and also a plurality of spaced, parallel T-grooves which extend thereacross, said T-grooves being in spaced, parallel alternating relationship with said rib members and being defined in a common face thereof; (E) each one of said end wall members being further characterized by having transversely extending across each one of a pair of opposed edge portions thereof, a surface portion which terminates along a common face thereof and which is also defined to make a mating and abuting engagement with one of a pair of opposed end edge portions of each one of said side wall members; (F) wall joining means mounting said side wall members in such engagement with said end wall members and which screens the resulting joints against electromagnetic fields and also seals said resulting joints against penetration of water and water vapor; (G) said T-grooves being adapted to receive therein slidably nut means of bolt and nut assembly means; and (H) said channel members being adapted to stiffen said housing construction and to dissipate heat generated therewithin.
Claim 2
Dependent Claim 242 words
A housing construction for electrical components comprising (A) two spaced, opposed, flattened side wall members; (B) two spaced, opposed, flattened end wall members; (C) each one of said side wall and end wall members being an extruded profile comprised of an aluminum alloy; (D) each one of said side wall members being further characterized by having integrally defined therein a plurality of spaced, parallel channel members which extend through and thereacross, and also a plurality of spaced, parallel T-grooves which extend thereacross, said T-grooves being in spaced, parallel alternating relationship with said rib members and being defined in a common face thereof; (E) each one of said end wall members being further characterized by having transversely extending across each one of a pair of opposed edge portions thereof, a surface portion which terminates along a common face thereof and which is also defined to make a mating and abuting engagement with one of a pair of opposed end edge portions of each one of said side wall members; (F) wall joining means mounting said side wall members in such engagement with said end wall members and which screens the resulting joints against electromagnetic fields and also seals said resulting joints against penetration of water and water vapor; (G) said T-grooves being adapted to receive therein slidably nut means of bolt and nut assembly means; and (H) said channel members being adapted to stiffen said housing construction and to dissipate heat generated therewithin.
