Abstract: An explosion proof connector is provided with first and second electrical connectors and first and second threaded sidewalls that surround the electrical connectors. The threaded sidewalls engage to secure the electrical connectors in electrical connection. Either the first threaded sidewall is rotatable relative to the first electrical connector or the second threaded sidewall is rotatable relative to the second electrical connector. A ratchet lock is carried by the first sidewall, and a ratchet surface is carried by the second sidewall, the ratchet lock being releasable and biased toward engagement with the ratchet surface. The ratchet lock permits rotation of the second sidewall relative to the first sidewall in a first direction and prevents rotation of the second sidewall relative to the first sidewall in a second direction. A release mechanism disengages the ratchet lock and permits the second sidewall to rotate in the second direction relative to the first sidewall.

Abstract: A waterproof connector is a connectable to a device-side connector (80) and has a housing (30) with a fitting (34) that can fit into an outer tube (82) of the device-side connector (80). A connector seal ring (36) is fit on an outer peripheral surface of the fitting (34) and is held resiliently in close contact with the outer tube (82) and the fitting (34). Individual terminal accommodating portions (37) are provided in the housing (30) and can fit into device-side cavities (84) provided in the device-side connector (80). Individual seal rings (38) are fitted on outer peripheral surfaces of the individual terminal accommodating portions (37) and are held resiliently in close contact with inner peripheral surfaces of the device-side cavities (84) and the individual terminal accommodating portions (37). The connector seal rings (36) and the individual seal rings are displaced in a front-rear direction.

Abstract: The present invention discloses a weight-bearing socket and plug for a pendent lamp, and the pendent lamp can be installed and disassembled only by inserting or unscrewing the plug.

Abstract: An SMT electrical keyhole connector includes a flat mounting portion for surface mounting on a PCB and two spaced contact portions each provided with an aperture in a shape of a keyhole that defines a longitudinal insertion axis and includes an upstream open region dimensioned to receive with clearance an insulated conductor having a metallic conductor generally having a diameter d1 surrounded by an outer insulation coating generally defining a diameter d2 and a downstream elongated slot formed by parallel opposing edges spaced from each other a distance h less than d1. Cutting edges cut or strip insulation off an insulated conductor. A retainer prevents a stripped conductor from moving upstream back into the open region to insure positive contact with the conductive wire or wires after the conductor is urged downstream into and is fully seated within the elongated slot.

Abstract: A fan is disclosed. The fan includes a fan frame and a plug. The fan frame includes a circumference portion, an accommodating portion located in the circumference portion and having two sidewalls, and at least two fixed holes respectively disposed on two sidewalls of the accommodating portion. The plug disposed in the accommodating portion of the fan frame includes a base, a bipolar knife-shaped terminal and a cover. The base includes two sides and two connecting portions respectively disposed on the sides to connect the fan frame. The bipolar knife-shaped terminal is disposed on the base and located between the connecting portions of the base. The cover is engaged to the base.

Abstract: A quick connect electrical junction box assembly for receipt and support of electrical appliances including a first support member adapted to be attached to a building, the first support member having a female electrical receptacle connected thereto, a second support member to support an electrical appliance, the second support member having a male electrical plug rotatably connected thereto, the male electrical plug being adapted to be received in the female electrical receptacle to make an electrical connection between first support member and the second support member, the second support member having at least one load bearing connector, the load bearing connector being adapted to be received in the first support member to connect the second support member to the first support member, the load bearing connector being spaced apart from the male electrical plug.

Abstract: A ceiling fan or light fixture hanging system that comprises a male and female electrical connector and ramp lock quick connection for installation of a ceiling fan or light fixture to an electric outlet box located on a ceiling.

Abstract: The present invention is directed to the general field of ceiling fans and more particularly to the field of ceiling fans with easy install features. Such a fan includes an electrical quick connect device and an articulating fan blade assembly. The quick connect device includes a plug/receptacle configuration enabling the fan to easily connect to an electricity supply while providing the gravitational and rotational support required by the fan. The fan blade assembly includes a drive hub having a series of slots to receive the neck of a fan blade. The fan blade neck is secured in the slot in a fashion that allows for articulation of the blade relative to the fan or removal of the fan blade from the fan.

Abstract: A mounting device for mounting an electrical fixture to an overhead support and electrically connecting the fixture to an electrical supply. The mounting device includes a mounting plate, a coupling plate, an electrical receptacle and an electrical plug. The device also includes a cap for covering receptacle terminals and a ball and socket support for the fixture. The mounting plate attaches to a junction box and contains the receptacle, which connects to an electrical supply. The coupling plate attaches to an electrical fixture and rotatably engages the receiving plate. The plug is rotatably secured to the coupling plate and includes a plurality of electrical conductors and a skirt surrounding the conductors. The receptacle includes a body having a plurality of sockets for receiving the conductors and an outer periphery shaped to slidably engage the inner periphery of the plug skirt. Rotation prevention screws may be used to avoid plate separation.

Abstract: A waterproof connector includes a pair of mating connector housings having connecting terminal fittings therein. A covering body rotatably is attached to a cylindrical peripheral wall of one of the connector housings. The covering body has a stopper hook projecting from its inner wall and is mounted with a resilient member for exerting a reaction force to the other connector housing. A locking hook projects from an outer peripheral wall of the other connector housing and engages with the stopper hook of the covering body. An outer wall of the other housing is inserted into the covering body and the stopper hook engages with the locking hook so that the pair of connector housings completely engage and lock to each other.
