Abstract
A method and apparatus for interconnecting electronic circuit boards through the use of twisted wire jumpers which are formed from multifilament wire and which have enlarged bird cages formed along the pins. The pins are drawn through a stack of circuit boards to position the cages in contact with interconnection apertures located in the printed circuit boards. The frictional engagement of the cages in the apertures provides both electrical inter connection of, and mechanical coupling between the printed circuit boards.
Claims19
Interconnection apparatus comprising:
- a plurality of electronic assemblies positioned in a stack, each electronic assembly having an interconnection aperture, each interconnection aperture having an inner contact surface at the periphery of the aperture, the interconnection apertures of each electronic assembly aligning with the interconnection apertures of all the other electronic assemblies positioned in the stack;
- and
- an elongated twisted wire jumper extending within the aligned interconnection apertures of the stacked electronic assemblies, the jumper having a plurality of cage members positioned therealong, each cage member resiliently and conductively engaging the inner contact surface to electrically interconnect and mechanically couple the electronic assemblies together in the stack.
A method of electrically interconnecting a plurality of electronic assemblies, each assembly having an interconnection aperture with an inner contact surface at the periphery of the interconnection aperture, comprising the steps of:
- stacking said assemblies to align said interconnection apertures of all the assemblies in the stack;
- inserting a twisted wire jumper in the aligned interconnection apertures, the jumper having a plurality of resilient bulged cage members for frictional engagement with the inner contact surface of said interconnection apertures;
- and
- drawing said twisted wire jumper within said aligned interconnection apertures to position the bulged cage members in resilient frictional mechanical and electrical engagement with the inner contact surface of said interconnection apertures.
