A first direction exposed conductor group includes a plurality of exposed conductor portions of a first flat cable, and a second direction exposed conductor group includes a plurality of exposed conductor portions of a second flat cable. The plurality of exposed conductor portions are located parallel to each other, and the plurality of exposed conductor portions are located parallel to each other. The first direction exposed conductor group and the second direction exposed conductor group intersect and overlap each other to form an intersection overlap portion. An intersection insulating film is provided between the first direction exposed conductor group and the second direction exposed conductor group at the intersection overlap portion. The exposed conductor portions and the exposed conductor portions facing each other via windows of the intersection insulating film are connected to be conductive to each other. Thus, an electric cable structural body is provided.

An electrical connection between two electrical harnesses is provided. The electrical harnesses include flexible printed circuits with embedded conductive tracks, each of which terminates in a receiving hole in a respective terminating region The terminating regions are connected together using conductive pins. The connection formation is then encapsulated by an encapsulating body formed of an insulating. The encapsulating body seals and protects the electrical connection, which is thus reliable and robust.

A cell contact-making system for an electrochemical device that includes a plurality of electrochemical cells is provided. The cell contact-making system includes a signal conductor system having one or more signal conductors for electrically conductively connecting a signal source to a signal conductor terminal connector or to a monitoring arrangement of the electrochemical device, wherein the signal conductor system includes at least one flexible printed circuit, wherein the flexible printed circuit includes at least one flexible insulating film and at least one conductor track that is arranged on the insulating film.

A first connection portion is formed at an end portion of a flexible conductor by folding the end portion of the flexible conductor in halves along a folding line extending in a given direction, and a contact-side connection portion of a contact presses the first connection portion from opposite sides in a thickness direction of the first connection portion to thereby electrically connect the contact to the flexible conductor.
