Techniques facilitating electrical coupling within cryogenic environments are provided. In one example, an electrical coupling device for a cryogenic electronics system can comprise a flexible wiring strip that includes non-superconducting wiring and a thermal break that includes superconducting wiring. The superconducting wiring can be coupled with the flexible wiring strip to bridge a gap defined, in part, by the flexible wiring strip. The superconducting wiring comprises higher electrical conductivity and lower thermal conductivity than the non-superconducting wiring.

A cable connection structure includes a cable, a sheet-like wiring member, and a cable junction connector. The cable junction connector includes a first fitting and a second fitting. A connection portion of the first fitting and a connection portion of the second fitting interlock with each other in a state in which a part of a conductor formed on the sheet-like wiring member is sandwiched between a plate portion of the first fitting and a plate portion of the second fitting. The first fitting has an insulation-displacement contact which includes an open-ended slot. The cable is forced into the open-ended slot. A direction in which the cable is forced into the open-ended slot is perpendicular to a direction in which the cable extends and is parallel to a direction in which the part of the conductor is sandwiched between the plate portion of the first fitting and the plate portion of the second fitting.

An electrical connection encapsulation device for electrically connecting a flexible flat cable to discrete electrical wires. The device includes a flexible flat cable with a dielectric, planar, flexible carrier and at least one electrically conductive line attached to at least one surface, first and second flat, soft and pliable material layers attached to the first surface and the second surface of the flexible carrier, respectively, by adhesive bonds, at least one electrical connector member that is electrically connectable to a discrete electrical wire at one end and to the at least one electrically conductive line with the other end. The first and second layers are arranged to at least partially overlap the at least one electrically conductive line in the connecting end region in the perpendicular direction, and to extend beyond the end of the at least one electrical connector member that is facing away from the connecting end region.
