Abstract
Abstract A modular electronic system is constructed by the interconnection of modules containing individual circuits. Each module includes a set of contact pads disposed at sites which are predesignated for the interconnection of corresponding terminals in the various circuits, which terminals are to be interconnected upon assembly of the system. The contact pads are disposed on the exterior surfaces of the modules and in a predetermined arrangement so that all electric connections can be accomplished unambiguously and only upon proper alignment of the modules. Activation of individual circuits may be delayed until completion of assembly by use of a sensing circuit in each module which determines that assembly has been completed or, alternatively, a displaceable connecting plate mounted on a resilient surface may be employed for springing out of connection when the modules are displaced from each other and making connection for activation of the circuits when the modules are contiguous to each other.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
209 words
A modular electronic interconnection system for the interconnection of a group of electrical apparatus constructed as separate circuits enclosed in individual cases wherein: each of said cases has an exterior surface configured for mating with a corresponding surface of another of said cases; each of said cases comprises a set of electrical contact pads disposed in a predetermined arrangement on said exterior surface, each contact pad being associated with a specific function of the circuit enclosed within the case; electrical connection between the apparatus being made by placing cases of the apparatus contiguous to each other with a mating of corresponding ones of said exterior surfaces and a contacting of corresponding ones of said contact pads on each of said cases, the same predetermined arrangement of the contact pads being present in a plurality of said cases to permit interconnection of corresponding contact pads upon a mating of said exterior surfaces; said system further comprising: interlock means in each of said cases automatically operable upon said electrical connection being made between the apparatus for then connecting individual ones of said contact pads in individual ones of said cases with terminals of the circuits contained in said cases to permit the flow of electric signals between circuits of the apparatus.
Claim 2
Dependent Claim
209 words
A modular electronic interconnection system for the interconnection of a group of electrical apparatus constructed as separate circuits enclosed in individual cases wherein: each of said cases has an exterior surface configured for mating with a corresponding surface of another of said cases; each of said cases comprises a set of electrical contact pads disposed in a predetermined arrangement on said exterior surface, each contact pad being associated with a specific function of the circuit enclosed within the case; electrical connection between the apparatus being made by placing cases of the apparatus contiguous to each other with a mating of corresponding ones of said exterior surfaces and a contacting of corresponding ones of said contact pads on each of said cases, the same predetermined arrangement of the contact pads being present in a plurality of said cases to permit interconnection of corresponding contact pads upon a mating of said exterior surfaces; said system further comprising: interlock means in each of said cases automatically operable upon said electrical connection being made between the apparatus for then connecting individual ones of said contact pads in individual ones of said cases with terminals of the circuits contained in said cases to permit the flow of electric signals between circuits of the apparatus.
Claim 3
Dependent Claim
83 words
A system according to claim 1, wherein said predetermined arrangements of electrical contact pads is present on opposite sides of each of said cases and in each of said cases there being a portion of said set of contact pads which are connected to terminals of the circuit enclosed within the case while the unused terminals in said sets of contact pads on opposite sides of the case are connected together, so as to permit both horizontal and vertical stacking of said apparatus.
Claim 4
Dependent Claim
74 words
A system according to claim 1, wherein said interlock means comprises a switch assembly of which a first portion is disposed in the exterior surface of one of said cases and a second portion is disposed in the corresponding position of the exterior surface of a second of said cases for coacting with each other to energize the electric circuit contained in said one of said cases upon a mating of said exterior surfaces.
Claim 5
Dependent Claim
32 words
A system according to claim 3, wherein said first portion of said switch assembly is one of a reed switch and a Hall effect switch and said second portion is a magnet.
Claim 6
Dependent Claim
53 words
A system according to claim 4, wherein said interlock means further comprises a relay in said one of said cases for supplying power to the circuit of said case, and a logic circuit responsive to the operation of said reed switch or Hall effect switch for activating said relay to supply said power.
Claim 7
Dependent Claim
67 words
A system according to claim 3, wherein said first portion of said switch assembly is a movable member resiliently mounted for displacement relative to a plurality of terminals of the circuit in said one of said cases for electrically connecting said terminals upon displacement of said member, and wherein said second portion of said switch assembly pushes against said member upon a mating of said exterior surfaces.
Claim 8
Dependent Claim
70 words
A system according to claim 6, wherein comprises a recessed portion is provided in a side of said one of said cases at the side of said exterior surface, said second portion of said switch assembly protruding from the side of said second of said cases and having a peripheral edge which is configured to mate with a peripheral edge of said recessed portion in said one of said cases.
