Claim 5

A modular package as defined in claim 3, wherein said metallic case includes a recessed back end and a lip which engages the free ends of said pair of tangs when said metallic case is telescoped over said projected backplate.

Claim 6

A modular package as defined in claim 1, wherein said metallic case has at least one exterior surface provided with fins for dissipating the heat produced by the electrical equipment.

Claim 7

A modular package as defined in claim 1, wherein a plurality of grooves are formed inside of said metallic case so that printed circuit boards are insertable into and removable from said metallic case.

Claim 8

A modular package as defined in claim 1, wherein said U-shaped cover is slid into place with said metallic case.

Claim 9

A modular package as defined in claim 1, wherein a mulTiple electrical connector is mounted on said backplate of said mounting bracket and a matching multiple electrical connector is positioned within said recessed back end of said metallic case.

Claim 10

A modular package as defined in claim 5, wherein component mounting pads are formed between the fins on said one exterior surface.

Claim 11

A modular package as defined in claim 1, wherein said metallic case is a boxlike structure having heat dissipating fins formed on the upper and lower exterior surfaces and having component carrying card grooves formed on the upper and lower internal surfaces.

Claim 12

A modular package as defined in claim 2, wherein said backplate includes a plurality of apertured angular mounting legs and said baseplate includes a plurality of mounting holes.

Claim 13

A modular package as defined in claim 1, wherein said metallic case includes a plurality of elongated internal grooves and a plurality of electrical connectors for accommodating a plurality of printed circuit boards.

Claim 14

A modular electrical equipment package comprising a mounting bracket constructed of a back portion, a base portion and a pair of side portions, said back portion having a pair of slightly inclined laterally extending tabs and a threaded aperture, a boxlike metallic case having at least one exterior surface provided with heat radiating fins and having a plurality of internal elongated grooves for accommodating printed circuit boards, said boxlike metallic case having a portion of both sides and front protected by a slidably removable cover, said boxlike metallic case having a passageway extending from front to back and having a lip formed near the back thereof which engages the free ends of said pair of laterally extending tabs, and an elongated retaining screw extending along said passageway of said boxlike metallic case and threadedly engaging said threaded aperture for securely holding said boxlike metallic case in proper relationship with said boxlike metallic case in proper relationship with said mounting bracket.

Claim 15

A modular electrical equipment package comprising a mounting bracket constructed of a back portion, a base portion and a pair of side portions, said back portion having a pair of slightly inclined laterally extending tabs and a threaded aperture, a boxlike metallic case having at least one exterior surface provided with heat radiating fins and having a plurality of internal elongated grooves for accommodating printed circuit boards, said boxlike metallic case having a portion of both sides and front protected by a slidably removable cover, said boxlike metallic case having a passageway extending from front to back and having a lip formed near the back thereof which engages the free ends of said pair of laterally extending tabs, and an elongated retaining screw extending along said passageway of said boxlike metallic case and threadedly engaging said threaded aperture for securely holding said boxlike metallic case in proper relationship with said boxlike metallic case in proper relationship with said mounting bracket.

Claim 16
