Abstract
Abstract The power supply leads are arranged in parallel in an insulating block and a rail on which a socket is fastened, having connecting means at its back, whereas its front side is adapted to accommodate a logic block and to transfer the information signals to the vicinity of said logic block. Applicable in particular in cyclically operating electronic, electro-optical or pneumatic control devices for industrial automation.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
229 words
Coupling and supporting means for logic blocks having first and second connecting means, said supporting means providing power supply connections to said blocks and interconnections between said blocks, said supporting means comprising: elongated means (21) of U-shaped cross-section having side walls fitted with first clamping means (23, 24) and having power supply leads (17, 18, 19) fitted in its internal part; a plurality of sockets (36) respectively associated with said logic blocks, each socket having side walls, a back surface provided with second clamping means (8) capable of removably engaging with said first clamping means and a front surface, exhibiting a main cavity for receiving at least a portion of a logic block, said front surface being provided with securing means (10) for retaining said block; first contact means (14) in said socket having a first extremity (15) in which said supply leads engages, and a second extremity (16) in which said first connecting means of said block engages; second contact means (11) having a first extremity (12) in which said second connecting means of said blocks engages, and a second extremity (13) located at said front surface of the socket, in the proximity of said main cavity and of one of said socket side walls, the various blocks being intercoupled by intercoupling said second extremities of said second means of the sockets respectively associated to said various blocks.
Claim 2
Dependent Claim
229 words
Coupling and supporting means for logic blocks having first and second connecting means, said supporting means providing power supply connections to said blocks and interconnections between said blocks, said supporting means comprising: elongated means (21) of U-shaped cross-section having side walls fitted with first clamping means (23, 24) and having power supply leads (17, 18, 19) fitted in its internal part; a plurality of sockets (36) respectively associated with said logic blocks, each socket having side walls, a back surface provided with second clamping means (8) capable of removably engaging with said first clamping means and a front surface, exhibiting a main cavity for receiving at least a portion of a logic block, said front surface being provided with securing means (10) for retaining said block; first contact means (14) in said socket having a first extremity (15) in which said supply leads engages, and a second extremity (16) in which said first connecting means of said block engages; second contact means (11) having a first extremity (12) in which said second connecting means of said blocks engages, and a second extremity (13) located at said front surface of the socket, in the proximity of said main cavity and of one of said socket side walls, the various blocks being intercoupled by intercoupling said second extremities of said second means of the sockets respectively associated to said various blocks.
Claim 3
Dependent Claim
57 words
Support means according to claim 1, wherein said elongated means is built up by a metal rail, the internal faces of said side walls of said elongated means comprising ribs 22, and wherein an insulating block is placed within said elongated means, comprising grooves for said power supply leads and recesses, said ribs fitting into said recesses.
Claim 4
Dependent Claim
78 words
Support means according to claim 1, wherein each socket is built up by a first and a second insulating casings cooperating with each other, said first casing comprising said back surface and said second clamping means cooperating with said first clamping means on said rail, said second casing comprising said front surface and said main cavity for the logic block, both casings further comprising sub-cavities communicating with said main cavity for receiving said first and second contact means.
Claim 5
Dependent Claim
96 words
Supporting means according to claim 3, wherein said second extremity of said first contact means is placed in a sub-cavity open towards the main cavity and is prong-shaped, the prong being open towarDs the main cavity, said first connecting means of said blocks terminating in said sub-cavity between the arms of said prong, said first extremity of said first contact means traversing said back surface, and wherein said first extremity of said second contact means is placed in a sub-cavity open towards said main cavity and is prong-shaped, the prong being open towards the main cavity.
