A wiring terminal includes a housing, a clamping and connecting piece, and a pressing piece. The housing is provided with a mounting channel and an insertion hole communicating with the mounting channel. The clamping and connecting piece is provided with a curved spring plate for clamping a conducting wire and a conductive sheet. The spring plate has a natural state in which the conducting wire placed in the mounting channel is clamped between the spring plate and the conductive sheet through elastic abutment, and a pressed state in which the spring plate is controlled by external force to deform in a direction distal from a clamped conducting wire. The pressing piece is capable of triggering the spring plate to switch between the natural state and the pressed state to unclamp the conducting wire.

A clamping spring for a screwless connection terminal for clamping a conductor, has a clamping limb, a contact limb, and a tensioning limb, the tensioning limb being connected to the clamping limb and the contact limb, and the clamping limb and the contact limb being designed as intersecting limbs. In the clamping limb, a clamping opening is provided, through which the contact limb extends, such that the contact limb is in contact with an edge of the clamping opening remote from the tensioning limb in a pretensioned manner and an exposed wire end of a conductor can be clamped with the contact limb onto a contact surface of a contact element of a screwless connection terminal. Furthermore, the clamping limb has a clamping extension having a clamping surface. The clamping extension, starting from the free end of the clamping limb remote from the tensioning limb, initially extends away from the tensioning limb, then extends back in the direction of the tensioning limb in a substantially curved form, and finally is oriented in the direction of the contact limb.

A wire connection device includes a housing, a conductor, and a lever. The conductor is located inside the housing and has a leaf spring, a conductive member and a push-back block, and the lever is provided with a push-back notch and an actuating cam, and the lever is movably assembled in the housing so that the lever may swing against the housing so that the leaf spring is squeezed by the lever for generating a deformation. When the lever swings to an actuate position, the touch surface of the cam that touch the conductor will be changed so that the lever can be moved in a straight line against the housing simultaneously. Therefore, the push-back block can be inserted into the inside of the push-back notch. In this way, when the push-back block is positioned inside the push-back notch, the lever is kept stay so that the leaf spring is kept in a state of deformation by the lever, and the wire can insert into the wire connection device without push the leaf spring, so that the wire connection device won't be damaged easily.

A spring terminal, in particular a direct plug-in terminal, for connecting a conductor such as a flexible stranded conductor includes a housing with a chamber and an insertion channel for inserting the conductor into the chamber. A busbar and/or a clamping cage are arranged in the housing and a clamping spring is arranged in the chamber and acts as a pressure spring. The clamping spring includes a clamping limb, said clamping limb releasable out of a latching state by a pusher having a latching edge on which the pusher can be latched in the interior of the housing on a latching hook of the busbar or another element arranged in the housing in a latching state. The pusher holds the clamping spring in a latched manner in the open position, wherein the latching edge of the pusher can be released from the latching state by an opposite movement.
