Abstract
Abstract The invention relates to an apparatus housing, comprising a first wall (1) and a second wall (2) which are interconnected by means of side walls (3, 4) and wherebetween a number of parallel component boards (5) are detachably arranged, transversely of the first wall (1) and the second wall (2). Each of the component boards (5) is detachably connected, by way of an edge, to a third wall (8) of the housing which is arranged transversely of the side walls (3, 4) and the first wall (1) and the second wall (2). At their edge which is remote from the connection, the component boards (5) are provided with a guide bracket (12) whereby they are located in the housing. The guide brackets (12) are clamped onto the component boards (5) and serve as spacers between these boards (5) and the walls (1, 2, 3, 4) of the apparatus housing. The boards (5) can thus be simply slid into and out of the apparatus housing which may have a comparatively light and inexpensive construction, because only few and light components are required for the locating of the component boards (5).

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
225 words
An apparatus of the type having a plurality of electrical component boards in a housing, comprising a plurality of component boards, each board having first and second edges, a third edge extending between said first and second edges, a fourth edge opposite said third edge, and an electrical connector disposed along said third edge, a housing having first and second walls opposite each other, a third wall extending between said first and second walls, and a respective plurality of electrial connectors arranged along said third wall, each of said boards having the connector along its third edge detachably connected to a respective connector along the housing third wall, the first and second edges of said boards being free of guiding connection to said housing, and a respective plurality of guide brackets, each bracket having a groove into which a fourth edge of a component board is received, clamping means for releasably retaining each bracket on the respective board, and spacer cams extending from the bracket generally perpendicular to the component board, each cam having a free end, said cams being so arranged that free ends of cams from adjoining brackets abut each other so as to space the respective components boards in a predetermined relationship, space between cams extending in a same direction from a bracket allowing free flow of air between the adjoining brackets.
Claim 2
Independent Claim
225 words
An apparatus of the type having a plurality of electrical component boards in a housing, comprising a plurality of component boards, each board having first and second edges, a third edge extending between said first and second edges, a fourth edge opposite said third edge, and an electrical connector disposed along said third edge, a housing having first and second walls opposite each other, a third wall extending between said first and second walls, and a respective plurality of electrial connectors arranged along said third wall, each of said boards having the connector along its third edge detachably connected to a respective connector along the housing third wall, the first and second edges of said boards being free of guiding connection to said housing, and a respective plurality of guide brackets, each bracket having a groove into which a fourth edge of a component board is received, clamping means for releasably retaining each bracket on the respective board, and spacer cams extending from the bracket generally perpendicular to the component board, each cam having a free end, said cams being so arranged that free ends of cams from adjoining brackets abut each other so as to space the respective components boards in a predetermined relationship, space between cams extending in a same direction from a bracket allowing free flow of air between the adjoining brackets.
Claim 3
Dependent Claim
44 words
An apparatus as claimed in claim 1, characterized in that said housing further comprises side walls extending between said first and second walls, and said brackets serve as spacers between the boards and the side walls as well as the first and second walls.
Claim 4
Dependent Claim
34 words
An apparatus as claimed in claim 2, characterized in that said clamping means consists of at least one clamping cam on each bracket arranged to engage a respective recess in the respective component board.
Claim 5
Dependent Claim
24 words
An apparatus as claimed in claim 2, characterized in that the guide brackets include a search edge disposed near corners of the component boards.
