A cable core for a cable, in particular, for an induction cable that includes multiple such cable cores which have a conductor that is interrupted in the longitudinal direction at specified longitudinal positions at multiple separation points, thereby forming two conductor ends. An insulating intermediate piece is provided for connecting the conductor ends, and the conductor ends are arranged on both sides of the intermediate piece. The conductor and the intermediate piece are surrounded together by a continuous insulating jacket in order to form the cable core. In a preferred concept, a respective intermediate piece is arranged between the two conductor ends by two adapter elements. In another preferred concept, a respective intermediate piece, in particular, a ceramic intermediate piece, is connected directly to two conductor ends. A cable is formed from a plurality of such cable cores.

A cable splice assembly includes a tubing encapsulated cable, an electric submersible downhole cable, where the tubing encapsulated cable and the electric submersible downhole cable are tape-spliced through a pair of respective contacts, and a thermoplastic insulator to seal the tubing encapsulated cable.

The present disclosure relates to connectors for high density neural interfaces and methods of microfabricating the connectors. Particularly, aspects of the present disclosure are directed to a connector having a core and a supporting structure wrapped around at least a portion of the core. The supporting structure may have a first layer of a high temperature liquid crystal polymer, and the second layer of a low temperature liquid crystal polymer that is reflowed to attach the supporting structure to the core. Conductive traces are buried between the first layer and the second layer, and the conductive traces terminate at conductive contacts formed on a surface of the first layer. The connector may have a predetermined shape or profile, which facilitates alignment and insertion of the connector into a header of a neurostimulator.
