A connection unit includes a plurality of connection elements arranged next to one another. Each connection element has a conductor connection opening for accommodating an electrical conductor and an actuating element for clamping the electrical conductor in the conductor connection opening and/or releasing said conductor. The actuating elements and the conductor connection openings are arranged on a common side of the connection unit. The actuating elements and the conductor connection openings of the connection elements are arranged in two rows which are spaced apart from one another. The connection unit has at least one first connection element of which the actuating element is arranged in a first row and the conductor connection opening is arranged in a second row, and at least one second connection element of which the actuating element is arranged in the second row and of which the conductor connection opening is arranged in the first row.

A wire-clamping connector is provided. The wire-clamping connector includes a housing and a contact element. The housing includes a through hole. The contact element is disposed in the housing, and includes a bottom plate structure and an elastic sheet body. The bottom plate structure is disposed opposite to a top wall of the housing, and includes a protruding portion that has a contact surface. A terminal portion of the elastic sheet body is fixed to the top wall, and the elastic sheet body has an acute-angular structure configured to be adjacent to the contact surface. An insertion interval is defined between the acute-angular structure and the contact surface. A wire core of a wire inserted in the through hole enters the insertion interval and is clamped together by the acute-angular structure and the contact surface, and an elastic restoring force is generated by the pressed elastic sheet body.

A conductor connection terminal with an insulating material housing having a conductor insertion opening for inserting an electrical conductor in a conductor insertion direction, with a busbar and a clamping spring, wherein the clamping spring has a clamping leg and wherein the clamping leg and the busbar form a clamping point for the electrical conductor to be clamped. The insulating material housing has a base side, wherein the base side is arranged adjacent to the side of the busbar facing away from the clamping point and wherein the base side has an opening, wherein on the side of the busbar facing away from the clamping point, two contact tabs protrude from the busbar, wherein the contact tabs are designed to contact a second electrical conductor between the contact tabs, wherein the second electrical conductor can be led through the opening of the base side between the contact tabs.
