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.

A conductor connection terminal with a spring-force clamping connection, which has a busbar and a clamping spring for connecting an electrical conductor to the busbar by the clamping spring. An actuator acts on an actuation section of the clamping spring for displacing a clamping leg of the clamping spring from a clamping position to an open position. The actuator has a first pusher section with a first actuation contour and a second pusher section with a second actuation contour. The actuator displaces the clamping leg by a first displacement distance through interaction of the first actuation contour with the first effective contour when the actuator is displaced by a first actuation distance, and displace the clamping leg of the clamping spring by a second displacement distance through interaction of the second actuation contour with the second effective contour when the actuator is displaced by a second actuation distance.

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 having a wire manager and a plunger.

A connection assembly for connecting an electrical conductor includes: a current bar; a clamping spring having a holding leg and a clamping leg, the electrical conductor being clampable against the current bar by the clamping leg in a clamped position of the clamping spring; and an actuating element guidable along an actuation direction and by which the clamping spring is transferrable from the clamped position into an open position. The actuating element is braced with the clamping spring in the open position and holds the clamping spring in the open position.

A connection terminal for electrically connecting at least two cables includes at least one body; at least one cable socket for allowing the cable to be passed through the said body; at least one bridge for providing the electrical transmission between the cables; at least one spring with at least one pressing arm that exerts a force on the cable to contact the cable with the said bridge; and at least one latch for controlling the position of the said spring.

A connection terminal for connecting an electrical wire includes: a housing having an insertion opening into which the electrical wire is insertable for connection to the connection terminal; a contact element arranged on the housing, the contact element electrically contacting the electrical wire; a spring element arranged on the housing, the spring element having a clamping portion for interacting with the electrical wire to bring the electrical wire into contact with the contact element; an actuation element pivotally arranged on the housing, the actuation element being movable from a non-actuated position into an actuated position so as to move the clamping portion; and a release element having a supporting end arranged to be stationary relative to the housing and a release portion elastically movable relative to the supporting end. The actuation element engages the release element when in the actuated position to hold the actuation element in the actuated position.

A connection assembly for connecting an electrical conductor includes: a current bar; a clamping spring having a holding leg and a clamping leg, the electrical conductor being clampable against the current bar by the clamping leg in a clamped position of the clamping spring; and an actuating element guidable along an actuation direction and by which the clamping spring is transferrable from the clamped position into an open position. The actuating element is braced with the clamping spring in the open position and holds the clamping spring in the open position.

A wire connection terminal structure includes a case main body. Wire plug-in ports are connected with an electro-conductive module. Arcuate slide guide slots are disposed on the electro-conductive module. Rotary buttons are pivotally disposed in the case main body. Each rotary button has a movable section. A pin is disposed on the movable section. The pin is extended into the slide guide slot. At least one abutment leaf spring is pivotally disposed between the rotary button and the electro-conductive module. When a conductive wire passes through the wire plug-in port into the lateral side of the electro-conductive module, the rotary button can be driven to make the movable section gradually displace from a section of the abutment leaf spring near the pivotally rotational center to an outer lateral side. The abutment leaf spring is pushed to engage with the conductive wire.

A connection terminal for connecting an electrical wire includes: a housing part; a contact element arranged on the housing part, the contact element having a contact portion for electrically contacting the electrical wire; a spring element having has a clamping leg that is adjustable relative to the housing part, the clamping leg acting on the electrical wire in a clamping position for contact with the contact portion; and an actuation element arranged on the housing part so as to be pivotable about a pivot axis, the actuation element being pivotable from an unactuated position into an actuated position so as to adjust the clamping leg from the clamping position. The actuation element has a first sliding face formed on a body portion of the actuation element. The housing part has a second sliding face formed on a housing portion.

A plug connection including a plug connector and a plug socket for electrically conductively connecting a circuit board. The plug connector has an insulating housing with a conductor insertion opening for guiding an electrical conductor into the insulating housing. A contact insert is received in the insulating housing, which has a busbar and a clamping spring. The insulating housing having a contact pin receiving opening for guiding a contact pin into the insulating housing. The busbar having a second clamping point for the contact pin. An actuating element is configured to open and/or close the first clamping point. An actuation of the actuating element is blocked by at least one of the insulating walls in an assembled state of the plug connector and the plug socket.
