Abstract
Abstract An all purpose electronic enclosure of electrically nonconductive material that adapts to various configurations and uses with a minimum of parts. A unitary receptacle portion has internal grooves to receive printed circuit boards, dividers and the like. One end of the receptacle portion is open. An optional cover closes the open end. Different cover constructions facilitate electrical connectors and mounting arrangements. External tracks on one or more sides of the enclosure receive plate-like members such as mounting plates, heat sinks, terminal block mountings and the like.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
146 words
An insulating enclosure for electronic components and the like, comprising: an electrically nonconductive, unitary, structure having four side walls and one end wall joined in box-like relationship to form a liquid-proof receptacle with an open end, A plurality of continuous guide surfaces extending along two opposite side walls and the end wall, substantially parallel to the other two side walls, for receiving edge portions of a thin, flat, board or plate and for spacing the board or plate from said other two side walls, a cover removably fastened to said structure over the open end with at least one slot in the cover extending between said two opposite side walls and through which a portion of said board or plate can extend, said cover having two flanges along opposite sides of said slot extending into the receptacle a distance greater than the width of the slot.
Claim 2
Dependent Claim
146 words
An insulating enclosure for electronic components and the like, comprising: an electrically nonconductive, unitary, structure having four side walls and one end wall joined in box-like relationship to form a liquid-proof receptacle with an open end, A plurality of continuous guide surfaces extending along two opposite side walls and the end wall, substantially parallel to the other two side walls, for receiving edge portions of a thin, flat, board or plate and for spacing the board or plate from said other two side walls, a cover removably fastened to said structure over the open end with at least one slot in the cover extending between said two opposite side walls and through which a portion of said board or plate can extend, said cover having two flanges along opposite sides of said slot extending into the receptacle a distance greater than the width of the slot.
Claim 3
Dependent Claim
39 words
An enclosure as set forth in claim 1 wherein said cover has two studs at opposite ends of the slot extending in a direction opposite from said flanges and for a distance greater than the width of the slot.
Claim 4
Dependent Claim
126 words
An insulating enclosure for electronic components and the like, comprising: an electrically nonconductive, unitary, structure having four side walls and one end wall joined in box-like relationship to form a liquid-proof receptacle with an open end, a plurality of continuous guide surfaces extending along two opposite side walls and the end wall, substantially parallel to the other two side walls, for receiving edge portions of a thin, flat, board of plate and for spacing the board or plate from said other two side walls, and two spaced parallel projections on one side wall externally of the receptacle, each having a groove parallel to and facing the other for slidably receiving and retaining a plate-like member relative to and externally of the receptacle formed by said structure.
Claim 5
Dependent Claim
126 words
An insulating enclosure for electronic components and the like, comprising: an electrically nonconductive, unitary, structure having four side walls and one end wall joined in box-like relationship to form a liquid-proof receptacle with an open end, a plurality of continuous guide surfaces extending along two opposite side walls and the end wall, substantially parallel to the other two side walls, for receiving edge portions of a thin, flat, board of plate and for spacing the board or plate from said other two side walls, and two spaced parallel projections on one side wall externally of the receptacle, each having a groove parallel to and facing the other for slidably receiving and retaining a plate-like member relative to and externally of the receptacle formed by said structure.
Claim 6
Dependent Claim
15 words
An enclosure as set forth in claim 3 including a plate-like member in said grooves.
Claim 7
Dependent Claim
29 words
An enclosure as set forth in claim 4 wherein said plate-like member includes apertures and a terminal block secured to the member with feed-through leads extending through the apertures.
Claim 8
Dependent Claim

An enclosure as set forth in claim 7 including a channel-shaped cover engaging each said outwardly facing lip and extending across said projections.
Claim 11
Dependent Claim
47 words
An enclosure as set forth in claim 3 including an additional two spaced parallel projections with facing grooves carried from a second side wall opposed to said one side wall and externally of said receptacle for slidably receiving and retaining a plate-like member relative to said structure.
Claim 12
Dependent Claim
109 words
An insulating enclosure for electronic components and the like, comprising: an electrically nonconductive, unitary, structure having four side walls and one end wall joined in box-like relationship to form a liquid-proof receptacle with an open end, a plurality of continuous guide surfaces extending along two opposite side walls and the end wall, substantially parallel to the other two side walls, for receiving edge portions of a thin, flat, board or plate and for spacing the board or plate from said other two side walls, and an opening at the edge of one side wall at the open end of the receptacle through which wires or the like may pass.
Claim 13
Dependent Claim
109 words
An insulating enclosure for electronic components and the like, comprising: an electrically nonconductive, unitary, structure having four side walls and one end wall joined in box-like relationship to form a liquid-proof receptacle with an open end, a plurality of continuous guide surfaces extending along two opposite side walls and the end wall, substantially parallel to the other two side walls, for receiving edge portions of a thin, flat, board or plate and for spacing the board or plate from said other two side walls, and an opening at the edge of one side wall at the open end of the receptacle through which wires or the like may pass.
Claim 14
Dependent Claim
35 words
An enclosure as set forth in claim 10 including four external apertured lugs extending outwardly from walls of said structure which facilitate mounting the structure to a support or securing a cover to the structure.
