Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
273 words
A junction box comprising a wall, a plurality of profile rails fastened to said wall extending in a direction parallel to each other, each rail having a plurality of elongated rail slots formed in a surface parallel to said wall, said slots in a first rail being equi-distant from corresponding slots in adjacent second and third rails on opposite sides of said first rail, a plurality of base parts mounted in said slots, each base part comprising an upper portion, a lower portion and a shank between said portions, said lower portion comprising locking means for connecting said base part to a rail by inserting a portion of said locking means through a slot and rotating said base part not more than approximately one-quarter turn from an inserting position to a locked position, said shank extending from said rail a first distance when said base part is connected to said rail, and a plurality of connectors, each connector comprising means for electrically connecting an end of each of a plurality of incoming leads to respective outgoing leads, said upper portion of a base part comprising means for attaching an end of each of two connectors so arranged that a connector can be attached at opposite ends to a first base part locked in a slot in said first rail and to a second base part locked in a corresponding slot in said second rail, and another connector can be attached at opposite ends to said first base part locked in said slot to a third base part locked in a corresponding slot in said third rail, said connectors being parallel to said wall.
Claim 2
Dependent Claim
273 words
A junction box comprising a wall, a plurality of profile rails fastened to said wall extending in a direction parallel to each other, each rail having a plurality of elongated rail slots formed in a surface parallel to said wall, said slots in a first rail being equi-distant from corresponding slots in adjacent second and third rails on opposite sides of said first rail, a plurality of base parts mounted in said slots, each base part comprising an upper portion, a lower portion and a shank between said portions, said lower portion comprising locking means for connecting said base part to a rail by inserting a portion of said locking means through a slot and rotating said base part not more than approximately one-quarter turn from an inserting position to a locked position, said shank extending from said rail a first distance when said base part is connected to said rail, and a plurality of connectors, each connector comprising means for electrically connecting an end of each of a plurality of incoming leads to respective outgoing leads, said upper portion of a base part comprising means for attaching an end of each of two connectors so arranged that a connector can be attached at opposite ends to a first base part locked in a slot in said first rail and to a second base part locked in a corresponding slot in said second rail, and another connector can be attached at opposite ends to said first base part locked in said slot to a third base part locked in a corresponding slot in said third rail, said connectors being parallel to said wall.
Claim 3
Dependent Claim
43 words
A junction box as claimed in claim 1 wherein said attaching means is so arranged that connectors attached between corresponding base parts on adjacent rails are staggered with respect to each other and are slanted with respect to the direction of said rails.
Claim 4
Dependent Claim
59 words
A junction box as claimed in claim 2 wherein said attaching means comprises two holes in said upper portion, said connectors each having end brackets for insertion through said holes for attaching said connectors to said base parts, at least one end bracket on each connector being resilient and arranged to lockingly engage the hole in the upper portion.
Claim 5
Dependent Claim
43 words
A junction box as claimed in claim 2 wherein passages for passing cables and leads are formed parallel to said rails, a passage being bounded by said wall, under surfaces of said connectors, and the shank portion of base parts on adjacent rails.
