Abstract: A wall-mountable programmable electronic thermostat for controlling an HVAC system is described. The thermostat includes a circular wall-mountable backplate with a central opening to allow for the passage of HVAC wires for electrical connection to the thermostat. The head unit body is also circular and is removeably mountable to the back plate. A plurality of wedge-shaped wiring terminals are mounted on the backplate for making a tool-free connection to HVAC wires. Each wiring terminal has button that a user can depress while a wire is inserted in a wire hole. The terminals are arranged along one or more circular arcs about the central opening of the backplate such that the wire holes face the central opening and the buttons are located close to the outer periphery of the backplate.

Abstract: A single element electrical connector includes a single conductive contact element formed into a cage structure having a wire insert end and a wire contact end along a longitudinal centerline axis of the connector. The cage structure defines an upper pick-up surface having a surface area suitable for placement of a suction nozzle of a vacuum transfer device, as well as a pair of contact tines biased towards the centerline axis to define a contact pinch point for an exposed core of a wire inserted into the connector. A contact surface is defined by a member of the cage structure for electrical mating contact with a respective contact element on a component on which the connector is mounted.

TL;DR: The poke-in connector of the Present Disclosure as mentioned in this paper is a connector that facilitates the locking and unlocking of a wire by pushing the wire into the terminal when making contact with the wire.
Abstract: The Present Disclosure relates to a poke-in connector configured so that a wire can be contacted at the same time it is locked to a terminal, solely by the action of pushing the wire into the terminal. More specifically, it relates to a poke-in connector that facilitates locking and unlocking of a wire. The poke-in connector of the Present Disclosure comprises a terminal where a wire is inserted and locked while making contact, and a housing that covers the terminal and is formed as one piece with a locking release lever that releases the wire from the locked state. The locking release lever comprises a flexible extension part that has elasticity and extends from the housing, and a pressing part that is formed on the terminus of the flexible extension part and enables the removal of the wire by spreading the locking part of the terminal to either side when pressed.

TL;DR: A screwless-type terminal block comprising a housing, a clamping member in the housing, and a PCB conductive pin, and an actuating member is described in this paper, where the clamping is sprang loaded such as to be biased towards the PCB pin.
Abstract: A screwless-type terminal block comprising a housing, a clamping member in the housing, a PCB conductive pin, and an actuating member. The housing defines a first opening for receiving therein a wire end and a second opening through which extends the actuating member which has a operating knob outside of the housing and a cammed end adapted to displace the clamping member between locked and unlocked positions thereof respectively for securing the wire end in an electrically conductive manner with the PCB pin and for allowing the wire end to be inserted in or withdrawn from the housing. When rotated, the operating knob causes the cammed end to rotate about a longitudinal axis of the actuating member such that the cammed end causes the clamping member to selectively displace between the locked and unlocked positions. The cammed end includes a flat surface angled with respect to the longitudinal axis and contacting the clamping member which displaces along a plane parallel to this longitudinal axis. The clamping is sprang loaded such as to be biased towards the PCB pin. The operating knob and the housing are provided with visible indicators to indicate if the clamping member is in its locked or unlocked position. The terminal block is nestable in a side-by-side relationship with other similar terminal blocks.

TL;DR: In this article, a locking connector is provided for electrically interconnecting first (220) and second (14) electrical conductors, which includes an enclosure (12) that accommodates an electrical contact component (4) electrically exchanged with the first conductor (14).
Abstract: A locking connector (2) is provided for electrically interconnecting first (220) and second (14) electrical conductors. The connector includes an enclosure (12) that accommodates an electrical contact component (4) electrically interchanged with the first conductor (14). At least two spring locking clips (6, 8) are mounted in the enclosure (12) and serially arranged to face away from the inlet such that the clips are sequentially and resiliently opened by introducing the second conductor (14) into the enclosure through the inlet. The clips (6, 8) are spring biased to grip the second conductor (14) at a plurality of locations and hold the second conductor (14) in electrical interengagement with the contact component (4). This enables the second conductor (14) to resist disengagement from the contact component (4).
