Electrical connection between two busbars made of flat conductors and of an insulating layer disposed between the conductors

An electrical connection apparatus, comprising:

• two busbars,
• wherein each busbar comprises two flat conductors and an insulating layer disposed between the two flat conductors,
• wherein each busbar has a longitudinal edge, and wherein the longitudinal edges of the two busbars are arranged opposite to each other, and
• wherein the two conductors of each busbar run parallel to each other at a distance along the longitudinal edge of the respective busbar,
• a shaped body comprising an insulating material bridging the distance between the two conductors of both the busbars;
• and
• two electrically conductive contact elements forced against each other but electrically insulated from each other,
• wherein the shaped body and the conductors of both busbars on both sides of the shaped body are arranged between the two contact elements,
• wherein each contact element is configured to contact one conductor of each busbar via a structured contact surface and clamps the respective conductor against the shaped body, and
• wherein the contact surfaces of the contact elements for each conductor of the two busbars comprise a clamping rib extending parallel to the longitudinal edges, and
• wherein the contact elements are forced against each other by a plurality of clamping elements distributed along the longitudinal edges.
