A conductor terminal including a casing made of insulating material. A first spring-loaded clamping connection has a first conductor-receiving space for receiving a first electrical conductor. A second spring-loaded clamping connection has a second conductor-receiving space for receiving a second electrical conductor. The first spring-loaded clamping connection is connected to the second spring-loaded clamping connection via a busbar extending from the first conductor-receiving space to the second conductor-receiving space. The casing made of insulating material comprises multiple parts including a main casing part and at least a first cover part.

Configurations for push wire connectors and for electrical wiring devices that mate with or connect to the push wire connectors are disclosed. The push wire connectors have a housing and one or more contact assembly positioned within the housing. Each contact assembly has one or more contact openings to allow wires to pass through, and the housing has one or more wire entry openings that are angled so that wires that pass through the wire openings and the contact openings before engaging the contact assembly are angled.

A connection clamp for connecting at least two electrical conductors to one another, having an insulating housing with at least one first and one second conductor insertion opening that are arranged on mutually opposite sides of the insulating housing. A first spring-force clamping connection for electrically contacting a first electrical conductor inserted through the first conductor insertion opening and a second spring-force clamping connection for electrically contacting a second electrical conductor inserted through the second conductor insertion opening are provided. The first spring-force clamping connection is electrically connected to the second spring-force clamping connection via a bus bar. The first spring-force clamping connection has at least one first clamping spring for clamping the first electrical conductor against a first clamping point of the bus bar, the second spring-force clamping connection has a clamping leg for clamping the second electrical conductor against a second clamping point of the bus bar.

A conductor connection contact element for clamping an electrical conductor having at least one resilient force clamping connection. At least one first SMD-solder contact is arranged on an assembly face of the conductor connection contact element and configured for soldering to a contact surface. A conductor inserting region is formed by a sheet metal part of the conductor connection contact element. At least one conductor guiding base is oriented so as to form a guiding surface for the electrical conductor that is to be inserted. A material portion of the sheet metal part is adapted to be bent over at least one curved region to form a first SMD-solder contact and a region of the conductor guiding base that is oriented in an oblique manner with respect to the conductor inserting direction is adjacent to the at least one curved region.

A coupler optionally couples two sets of conductive wires. In some embodiments, the coupler includes a body having a first end with a first set of at least two holes and a second end with a second set of two holes. Optionally each hole includes a clamp. Optionally, each clamp of said first set of holes is conductively connected to at least one clamp of said second set of holes. In some embodiments a first rotating element simultaneous attaches to said coupler a first set of a plurality of wires inserted into said first set of holes and/or a second rotating element simultaneous attaches to said coupler a second set of a plurality of wires inserted into said second set of holes.

Configurations for push wire connectors and for electrical wiring devices that mate with or connect to the push wire connectors are disclosed. The push wire connectors have a housing and one or more contact assembly positioned within the housing. Each contact assembly has one or more contact openings to allow wires to pass through, and the housing has one or more wire entry openings that are angled so that wires that pass through the wire openings and the contact openings before engaging the contact assembly are angled.

An electrical terminal block arrangement includes a terminal block with at least one housing having a first insertion opening and a second insertion opening, and a clamping body including a contact metal, a first spring, and a second spring arranged inside the housing; a discharge resistor that includes a plug-in contact, the plug-in contact being plugged in through the first insertion opening of the housing; and a capacitor that includes at least one capacitor wire, the capacitor wire being inserted through the second insertion opening of the housing and being clamped and electrically contacted to the contact metal by the second spring.
