A connection housing includes a connection housing rear wall, at least one open area, and at least one connection device for a conductor. The connection device preferably has at least individual conductor connections. Each individual conductor connection has a metal contact element, a spring support which is made of a non-conductive material such as synthetic plastic, and includes a base wall and a clamping spring. The spring support is inserted into the open area such that the base wall lies parallel to the rear wall of the connection housing at a distance therefrom. The base wall forms a guide for conductors to be inserted, and the base wall completely or partly closes the housing towards the outside in the region of the open area.

A connection device for conductors has at least one double conductor connection for connecting two conductors. The conductor connections are formed as direct plug connections each having a metal clamping cage formed of a highly conductive material such as sheet metal. A clamping spring is mounted on each clamping cage. Each clamping cage serves as a spring support for a clamping spring and as a contact element for each conductor.

A terminal device includes: a housing having at least one contact cavity; a contact part which is arranged in the at least one contact cavity and into which at least one electrical line can be plugged in order to make electrical contact with the contact part; and at least one busbar which is arranged on the housing, is electrically connected to the contact part, and a busbar portion of which extends along a height line. An end portion adjoins the busbar portion, which end portion extends in an oblique direction at an oblique angle to the height line and can be moved along the height line relative to the contact part.

A kit or assembly for a ceiling fan can include a downrod and a set of electrical wires. The downrod can include a sidewall defining an interior. An opening can be provided in the sidewall for accessing the interior. The set of electrical wires can extend through the interior of the downrod, having first and second sets of wire tips, and can be longer than the downrod. An optional electrical connector can be provided on one of the first or second sets of wire tips.

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 spring-loaded terminal is designed as a direct plug-in terminal for connecting a conductor. The terminal includes a busbar for contacting the conductor, a clamping spring for retaining the electrical conductor in the terminal, and a retaining spring for latching the clamping spring in an open position so that the conductor can be inserted into a contact area. The clamping spring has a pivotable clamping leg and a clamping edge. The retaining spring has a pivotable pivoting leg having at least one retaining device as a first latching device. The clamping leg has a corresponding latching device cooperating with the retaining device of the pivoting leg in a latching state of the clamping leg. The clamping leg is adjustable from the latching state by displacing the electrical conductor into a clamping state in which the clamping leg is unlatched from the retaining device and presses the electrical conductor with the clamping edge of the clamping leg against the busbar. The latching device of the clamping leg is spaced from the clamping edge of the clamping leg.

A power wiring device includes a front housing having a power component at a user interface and a rear housing having a wire interface. The front and rear housings define a cavity. Control electronics are received in the cavity and include a circuit board and a controller coupled to the circuit board. The controller has control circuitry for controlling a power function of the power wiring device. The power component is coupled to the circuit board and affected by the power function. A plurality of power terminals are coupled to the circuit board. The power terminals each have a base, circuit board contacts extending from the base and being terminated to the circuit board, and wire contacts extending from the base. The wire contacts have quick connect interfaces for direct, quick connection to corresponding wires of building wiring.

An electrical apparatus such as an electrical contactor or a terminal block, comprises a casing made of an electrically insulating material, a conductive bar mounted in the casing and at least one push-in type connection terminal. The terminal comprises a contact spring having an elastic portion undergoing an elastic deformation under the action of an external force applied on the contact spring either by an electrical conductor during its insertion at a first aperture of the casing so as to place the electrical conductor in a contact position located between the contact spring and the conductive bar in order to establish an electrical connection between the electrical conductor and the conductive bar, or by a tool inserted into a second aperture of the casing so as to open the contact spring and release the electrical conductor in order to remove it out of its contact position. The electrical apparatus comprises a support clip independent of the casing and of the conductive bar. The clip comprises fastening elements allowing mounting of the support clip on the contact spring and delimits a bearing face against which the contact spring bears during the deformation of its elastic portion under the action of the external force in order to impose the manner in which the elastic portion spatially deforms and against which the contact spring abuts in its maximum deformation state in order to limit the elastic deformation of the elastic portion of the contact spring below a predetermined value regardless of the intensity of the external force.

An electrical distribution box including a bus bar with a quick connect assembly for engaging or disengaging wiring. The bus bar housing defines an interior chamber and includes a wall defining a plurality of holes and release ports therein A space bar within the chamber includes a plurality of spaced-apart fixed contacts and spring contacts. Each spring contact includes an arm that moves towards or away from the fixed contact and is partially aligned with one hole and one release port in the housing. The spring contact moves from an at rest position by inserting a wire through one of the holes. The spring contact locks the wire between itself and the fixed contact. The wire is release by inserting a tool through the release port and applying a linear force to the spring contact, thereby rotating the spring contact away from the fixed contact and releasing the wire.

A surface-mounted pluggable wiring insert key capable of being used for connecting structural parts of multiple strands of weak-current flexible wires, a driving power source box formed by using the surface-mounted pluggable wiring insert key, and a detachable modular LED lamp provided with the driving power source box structure. A damaged driving power source and other damaged assemblies can be conveniently replaced, abandonment of an LED chip having a long service life or even a whole LED lamp can be prevented, the designed structure is simple, and tin soldering is not required, thereby saving resources, greatly reducing use cost, and facilitating the popularization of the LED lamp.
