Abstract: A connection terminal for connecting at least one electrical conductor includes: a clamping element which is arranged on a receiving element so as to be able to pivot about a shaft between an open position and a clamping position, the clamping element forming, together with a contact element, a clamping point for the electrical conductor; and an actuating arm for receiving an actuating tool, a first free limb of the actuating arm being pivotally arranged on the clamping element so as to be spaced apart from the shaft thereof such that, by pivoting the actuating arm using the actuating tool, the clamping element is able to shift from the open position into the clamping position and vice versa. A second free limb of the actuating arm is movably guided over at least one cam.

Abstract: A terminal block arrangement includes a housing and a plurality of connection terminals, each connection terminal including at least one terminal unit for contacting at least one conductor, which can be received on the connection terminal, and at least one associated actuation unit for actuating the terminal unit in order to selectively transfer the terminal unit between at least two positions. At least one of the positions is an open position and at least one of the positions is a contact position. The terminal block arrangement also includes a blocking device, wherein, in a blocking position, the blocking device is capable of preventing, jointly, the actuation of the actuation units of at least two of the plurality of connection terminals.
