Abstract: A disabling device for electronic circuits includes a female connector with an easily accessible front surface and an inaccessible rear surface. A large array of contact pairs are found in the female connector. A predetermined number of input/output wires join the female connector in series with the circuit across randomly selected contact pairs in the array. A number of non-functional dummy wires also connect in the array to further complicate the non-uniform connection pattern. When a male connector containing an internal arrangement of jumper wires is inserted into the female connector, the jumper wires short across the proper contact pairs and close the circuit. Subsequent removal of the male element again opens and disables the circuit.

Abstract: A combined transient voltage and sneak current protector is presented. The protector device comprises a two-piece substantially rectangular insulative housing. The housing has four spaced and aligned openings at the bottom thereof for receiving upstanding terminals from a terminal block. The interior of the housing is loaded with four contact members which are adapted to effect electrical connection with a three element surge suppressor (e.g. transistor) and a pair of small cylindrical fuse elements. Each of the four contact members include a female connector communicating with the four aligned openings in the housing. The housing interior also includes a ground contact which electrically connects to the middle element on the surge suppressor. The ground contact passes through a lateral opening in the housing for mating with a novel plug-on grounding bus connector.

Abstract: A discretionary interconnect which includes orthogonal arrays of conductors sandwiched between conductive planes and accessible through a number of selectively arranged vias for interconnection and interruption. Also disclosed is a process of personalizing an interconnect of this type by selectively connecting and disconnecting the conductors.

Abstract: A bridging link is disclosed for electrically connecting each of a selected pair of insulation displacement terminals of a first terminal array to a respective one of a corresponding pair of insulation displacement terminals of a second terminal array. The bridging link comprises a dielectric body including a rigid housing, a first pair of spaced apart electrical contact members projecting from a first region of the housing, and a second pair of spaced apart electrical contact members projecting from a second region of the housing which is spaced apart from the first region. The contact members of the first pair are electrically connected through the housing each to a respective one of the contact members of the second pair.
