A connection terminal for connecting at least one conductor to a current bar, which is accommodated on a mount, in an electrically contacting manner, includes at least one clamping spring for applying a clamping force, the at least one clamping spring including a pivotable clamping lever for clamping the conductor. The clamping spring has a first leg and at least a second leg, is hingedly coupled to the clamping lever by the first leg, and is hingedly coupled to an auxiliary lever by the second leg, the clamping lever and the auxiliary lever being arranged pivotally on the mount.

A current bar for a connection arrangement for connecting an electrical conductor includes: a clamping portion, against which the electrical conductor inserted into the connection arrangement in an insertion direction is clampable. The clamping portion has a first function zone, a second function zone, and a third function zone. In an embodiment, viewed in the insertion direction, the second function zone is formed below the first function zone, and the third function zone is formed below the second function zone.

The present disclosure provides descriptions of configurations for wire connectors used to splice low voltage electrical conductors or to splice high voltage electrical conductors. The wire connectors may be coupled to form a wire connector assembly. Each wire connector includes a base, a cover, a first cover coupling assembly and a second first cover coupling assembly. The base has an upper wall and a lower wall and can be divided into a first end portion, a second end portion and a central portion between the first end portion and the second end portion.
