Electric cable connection system

An electric cable connection system, comprising:

• a cage-shaped busbar (2, 2′) which is fully or at least partially open on a cable connection side to allow an electrical cable (6) to be inserted, including
• a cage which has two cage walls, namely a first cage wall (21, 21′) and a second cage wall (23), and
• two lateral walls (22) which couple the first cage wall (21, 21′) and the second cage wall (23) to each other, wherein the two lateral walls (22)
• each have a step (24) on a cable insertion side, wherein the step (24)
• is formed by a slide edge (243) extending in a cable insertion direction and a counter stop edge (242);
• a V-shaped clamping spring (3, 3′), including
• a retaining leg (31) which is fastened to, or at least held against, the first cage wall (21, 21′) of the busbar (2, 2′),
• a spring bend (32) adjoining the retaining leg (31) and, adjoining thereto,
• a resiliently pivotable clamping leg (33), which
• can assume a non-actuated state in which it presses a contact portion (62) of the electrical cable (6) against the second cage wall (23) of the busbar (2, 2′) in the non-actuated state of the clamping spring (3, 3′), in order to electrically couple a core (60) of the electrical cable (6) to the busbar (2, 2′) and simultaneously to secure the cable (6) against unintentional withdrawal counter to the cable insertion direction;
• and which further
• can assume an actuated state in which it is pivoted, while applying a counterforce, in the cable insertion direction in order to release the cable (6) again as needed for withdrawing it from the cable insertion side;
• an actuator (1) for transferring the clamping spring (3, 3′) from the non-actuated state thereof to an actuated state,
• wherein the actuator (1) includes
• two lateral actuating arms (12) and
• a web (123) which couples the actuating arms (12) via ends thereof and is configured for actuating the clamping leg (33) of the clamping spring (3, 3′), wherein
• the web (123) extends perpendicularly to the slide edges (243) of the lateral walls (22) of the busbar (2, 2′) and is in mechanical contact with the slide edges (243), so it is able to slide along the slide edges (243) in order to guide the actuator (1);
• and
• the electrical cable (6), which includes
• the electrically conductive core (60),
• a transmission portion (61) comprising an electrically insulating sheath (610) which surrounds the core (60) in a radial manner, and
• the contact portion (62), which is located at an end of the cable (6) to be inserted into the busbar (2, 2′) and in which the cable (6) for establishing electrical contact with the busbar (2, 2′) does not have an electrically insulating sheath (610), so the core (60) of the cable (6) is not sheathed in this contact portion (62), and
• a collar (613, 613′) which is adjacent to the contact portion (62) and consists of an electrically insulating material;
• wherein the collar (613, 613′) of the electrical cable (6) is arranged on the cable insertion side of the web (123) of the actuator (1), and
• wherein the first cage wall (21′) of the cage-shaped busbar (2′) has a cage opening (20) or is even fully replaced by an opening (20) of this type, so the cage-shaped busbar (2′) is an open cage-shaped busbar (2′), and the clamping spring (3′), by means of the retaining leg (31) thereof, is at least held or even fastened against the first cage wall (21′) from an exterior by pressing, stamping, riveting, screwing, clamping, adhesively bonding and/or latching.
