Abstract
Abstract A multiple signal transmission unit includes input/output modules having top and bottom portions which are connected electrically and mechanically via a plug connection. The bottom portions are designed exclusively for the current supply of the neighboring module of a line of modules by spring contacts which pass through the bottom portions from lineup side to lineup side. These modules are in contact connection from bottom portion to bottom portion via the spring contacts, while all elements of the circuit are associated with the top portions for the control of the machines, subassemblies, and the like that are connected with the modules.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
125 words
A multiple signal transmission device for controlling equipment, comprising (a) a transmitter/receiver connected with a carrier rail; (b) at least one input/output module connected with said transmitter/receiver for transferring control signals relative to the equipment, said module including (1) a bottom portion connected with the carrier rail; and (2) a top portion electrically connected with said bottom portion via a plug connecting; (c) contact means connected with said module bottom portion and protruding laterally outwardly therefrom for engaging and electrically connecting said module bottom portion with a bottom portion of an adjacent module to provide current to said modules and data transfer therebetween, said contact means being electrically connected with said plug connection to supply current and transfer data relative to said module top portion.
Claim 2
Dependent Claim
125 words
A multiple signal transmission device for controlling equipment, comprising (a) a transmitter/receiver connected with a carrier rail; (b) at least one input/output module connected with said transmitter/receiver for transferring control signals relative to the equipment, said module including (1) a bottom portion connected with the carrier rail; and (2) a top portion electrically connected with said bottom portion via a plug connecting; (c) contact means connected with said module bottom portion and protruding laterally outwardly therefrom for engaging and electrically connecting said module bottom portion with a bottom portion of an adjacent module to provide current to said modules and data transfer therebetween, said contact means being electrically connected with said plug connection to supply current and transfer data relative to said module top portion.
Claim 3
Dependent Claim
38 words
A device as defined in claim 1, wherein said module bottom portion contains complementary guides on the sides thereof which engage the guides of an adjacent module to line up a plurality of modules on the carrier rail.
Claim 4
Dependent Claim
38 words
A device as defined in claim 1, and further comprising a pair of mutually linked frame halves surrounding said bottom portion and for receiving and retaining said module top portion to hold said module together as an assembly.
Claim 5
Dependent Claim
25 words
A device as defined in claim 3, wherein said frame halves each contain an opening for access to said end portions of said spring contacts.
Claim 6
Dependent Claim
130 words
A multiple signal transmission device for controlling equipment, comprising (a) a transmitter/received connected with a carrier rail; (b) at least one input/output module connected with said transmitter/receiver for transferring control signals relative to the equipment, said module including (1) a bottom portion connected with the carrier rail; and (2) a top portion electrically connected with said bottom portion via a plug connection; and (c) spring contacts connected with and passing through said module bottom portion between the contact lineup sides of said module for electrically connecting said module bottom portion with a bottom portion of an adjacent module to provide current to said modules and data transfer therebetween, said contact means being electrically connected with said plug connection to supply current and transfer data relative to said module top portion.
Claim 7
Dependent Claim
130 words
A multiple signal transmission device for controlling equipment, comprising (a) a transmitter/received connected with a carrier rail; (b) at least one input/output module connected with said transmitter/receiver for transferring control signals relative to the equipment, said module including (1) a bottom portion connected with the carrier rail; and (2) a top portion electrically connected with said bottom portion via a plug connection; and (c) spring contacts connected with and passing through said module bottom portion between the contact lineup sides of said module for electrically connecting said module bottom portion with a bottom portion of an adjacent module to provide current to said modules and data transfer therebetween, said contact means being electrically connected with said plug connection to supply current and transfer data relative to said module top portion.
Claim 8
Dependent Claim
35 words
A device as defined in claim 5, wherein said module bottom portion includes upper and lower insulating sections, said upper section containing a plurality of recesses opposite said lower section for receiving said spring contacts.
Claim 9
Dependent Claim
44 words
A device as define in claim 6, wherein said spring contacts are initially interconnected via studs, and further wherein said module bottom portion upper section includes projections between said recesses for breaking said studs away from said spring contacts during assembly of said module.
Claim 10
Dependent Claim
59 words
A device as defined in claim 6, wherein said upper insulating section contains contact chambers in the opposite sides thereof and said lower insulating section contains protrusions on the opposite sides thereof for directing the ends of said spring contacts into an adjacent contact chamber during assembly and for pressing the ends of said contacts into an erect position.
Claim 11
Dependent Claim
38 words
A device as defined in claim 8, wherein said lower section protrusions are configured to press said spring contacts into said chambers to an extent wherein said contacts are retained in an erect position without diminishing their elasticity.
Claim 12
Dependent Claim
34 words
A device as defined in claim 7, wherein one end portion of said spring contacts has a flat contact surface and the other end portions of said spring contact has a curved contacts surface.
