A lever connector for contacting electrical conductors includes features and improvements over other lever connectors. The lever connector includes a housing, a busbar located within the housing, one or more lever mechanisms, and one or more resilient members that connect the lever mechanisms to the busbar. The lever mechanism includes a lever located on a near side of the busbar bridge and a lifting mechanism located on a far side of the busbar bridge opposite the near side of the busbar bridge. When the lever is actuated and lifted upwards and away from the housing, the lifting mechanism moves the resilient member to release away from the busbar. When the lever is closed and pushed downward toward the housing, the lifting mechanism moves the resilient member downward to push the electrical conductor against the busbar, thereby making electrical contact between the electrical conductor and the busbar.

A spring-loaded terminal connection having a busbar and a clamping spring, which has a clamping arm, wherein the clamping arm extends towards the busbar and has a spring clamping edge for clamping an electrical conductor and wherein the busbar has a busbar clamping edge for fixing the electrical conductor to be clamped, wherein the busbar clamping edge has a radius less than or equal to 0.2 mm.

A connection arrangement for connecting an electrical conductor includes: a busbar; a clamping spring, which has a retaining leg and a clamping leg, the clamping leg being transferable into a clamping position and into a release position; a conductor connection space formed between a section of the busbar and of the clamping leg of the clamping spring; a displaceably arranged guide element, which is in operative connection with the clamping leg of the clamping spring, the clamping leg being holdable in the release position by the guide element; and an actuating element, by which the guide element is displaceable in order to transfer the clamping leg of the clamping spring from the clamping position into the release position. The clamping spring is arranged between the section of the busbar and the actuating element.

Electrical wiring devices that incorporate clamp-type wire terminal connections are described. The electrical wiring devices include for example, single and duplex blade-type electrical receptacles, blade-type locking electrical receptacles, single or multi-pole electrical switches, combination switches and blade-type receptacles, blade-type plugs for electrical cords and blade-type connectors for electrical cords. The electrical wiring devices include a plurality of contact assemblies. Each contact assembly includes a wire terminal and a plunger.

This utility model provides a wiring terminal, used for receiving and connecting to a conducting wire, the wiring terminal including: a housing, provided with a mounting channel and an insertion hole communicating with the mounting channel for the conducting wire to be inserted; a conductive piece and a clamping piece, both of which are arranged in the mounting channel, where the conductive piece and the clamping piece cooperate to form a natural state in which the conducting wire placed in the mounting channel is clamped between the clamping piece and the conductive piece through elastic abutment and a pressed state in which the conductive piece and the clamping piece are controlled by an external force to deform in a direction distal from the clamped conducting wire.

A power input terminal block includes terminals received in terminal channels of a housing each having a main body defining a wire pocket receiving a supply wire and a take-off tab electrically connected to the main body. The power input terminal block includes clamp contacts coupled to the take-off tabs each having a base, a spring beam extending from the base, and a cap extending from the spring beam having a poke-in window configured to receive a take-off wire. An edge defining the poke-in window engages the take-off wire and pulls the take-off wire against the wire side of the take-off tab. The power input terminal block includes release levers coupled to the housing to move the spring beam to an extended position to allow loading and removal of the take-off wire from the clamp contact and the take-off tab.
