A conductor connection terminal with a contact insert that has a bus bar and a clamping spring, and with a housing that has a first housing part and a second housing part and that at least partially encloses the contact insert, wherein the first housing part has a first housing wall with a receiving structure for receiving the contact insert, and the second housing part has multiple additional housing walls for covering the contact insert received by the first housing part. A conductor connection terminal is also provided with a contact insert that has a bus bar and a clamping spring, and with a housing that has a first housing part and a second housing part and that at least partially encloses the contact insert. The first housing part has a first conductor insertion channel section and the second housing part has a second conductor insertion channel section.

A spring connector includes: a tube; a movable pin having a distal end portion that protrudes from an opening of the tube, and having a hole portion that opens on a side opposite to a protruding direction; and a coil spring configured to bias the movable pin in the protruding direction. The coil spring includes an eccentric winding portion whose winding center is eccentric relative to an axial straight line connecting a winding center of a winding portion at one end portion and a winding center of a winding portion at the other end portion.

An electrical connector includes wiring with multiple wires. Each wire has a conductor covered in insulation. Each wire has a stripped portion that exposes the conductors. The stripped portions are stacked on top of one another. A housing has first and second housing portions that provide a cavity. The first housing portion receives the stripped portions. The second housing portion includes a spring that has a closed portion that extends into the cavity and is configured to urge the stripped portions into engagement with one another when the first and second housing portions are secured to another in an assembled connector condition.

A circuit breaker neutral connector assembly is provided. Circuit breaker neutral connector assembly includes a neutral connector including a first side configured to make electrical connection with a neutral bar, a shield of an insulating material abutting a second side of the neutral connector opposite the first side, and a bias spring abutting the shield and configured to bias the neutral connector relative to a circuit breaker housing. Electronic circuit breakers including a circuit breaker neutral connector assembly and methods of making neutral connections are provided, as are other aspects.

A connecting terminal for connecting at least two electrical conductors to one another, wherein the connecting terminal has at least two separate housing parts which are mechanically connected to one another and each have a conductor insertion opening for at least one electrical conductor which is to be connected on opposite housing sides, wherein there is a first spring-force clamping connection for making electrical contact with a first electrical conductor in a first housing part of the at least two separate housing parts, and there is a second spring-force clamping connection for making electrical contact with the second electrical conductor in the second housing part of the at least two separate housing parts. A method for fitting a connecting terminal for connecting at least two electrical conductors is also provided.

A wire connection terminal device includes a main body and a pressing/moving unit assembled with the main body. The pressing/moving unit has a shafted section, a cam section connected with the shafted section and a force application section formed on the cam section and a press section formed on the cam section. The cam section can freely rotate or swing within a chamber defined by the main body. A metal leaf spring is disposed in the chamber of the main body for pressing and electrically connecting with a conductive wire. The metal leaf spring is responsive to the motion of the pressing/moving unit to release the conductive wire. The wire connection terminal device improves the shortcomings of the conventional structure that the volume of the case and the operational space are larger and the motional travel is longer.

A plug-in terminal block includes at least one conductive assembly including a conductive component connected with a housing assembly and a clamping component arranged on the conductive component. The conductive component includes a first support portion, a first clamping portion, a first connecting portion connected with the first clamping portion, and welding feet. The first connecting portion and the welding feet separately extend along different directions from the first support portion. The clamping component includes a second support portion and a second clamping portion. The second support portion is arranged on the first support portion. The second damping portion is arranged above the second support portion. The first support portion, the first connecting portion, and the second clamping portion form a triangular structure. One end of the second clamping portion away from the second support portion is a free end that is movable up and down.

A conductive component structure of rail-type terminal device includes a conductive component disposed in an insulation case body. The conductive component has a first section and a second section connected with the base section. The first section and the second section are respectively formed with a bow portion, a first portion and a second portion. A load arm and an elastic unit assembled with the load arm are disposed on the first section and/or the second section. The elastic unit includes a first elastic section and a second elastic section. The load arm passes through the first elastic section and at least a part of the second elastic section. When the load arm is displaced or moved, the first elastic section and the second elastic section respectively provide tension (or pushback force) and pulling force effect so as to improve the shortcoming of the conventional terminal device.
