A conductor assembly structure for a rail-type terminal device includes a conductor assembly and an insulating housing. The conductor assembly structure can reduce manufacturing waste and has a larger contact surface and a better electric conduction effect. The conductor assembly has a base portion that can be pivotally connected with a conductive connector, and a first area and a second area connected to the base portion. The first area and the second area are respectively formed with a bowed portion and a first section and a second section connected to the bowed portion to be snapped onto a grounding mounting rail. At least one of the first area and the second area is provided with a load arm and an elastic member connected to the load arm for increasing the elastic fixing effect (force) of the first section and/or the second section on the grounding mounting rail.

An electrical wiring system providing selectable referencing to earth ground, comprising: a housing comprising a first terminal for attachment to HOT, a second terminal for attachment to LOAD, and a flexible terminal comprising a first leg mounted to the electrical wiring device and a second leg connected to the first leg via a flexible joint, wherein the relative distance between the first leg and the second leg is adjustable between an extended position and a retracted position by flexing the flexible joint, the flexible joint being biased in the extended position, wherein the first leg defines a first aperture and the second leg defines a second aperture, a load control circuit disposed within the housing and receiving a line input from the first terminal and a reference input, the reference input being referenced to the electric potential of the flexible terminal; a screw having a screw head, the screw being inserted through the first aperture and the second aperture; and a pressure plate having a threaded aperture, the threaded aperture being engaged with the threads of the screw, the pressure plate and the screw head being disposed on opposite sides of the flexible terminal such that advancing the pressure plate along the threads of the screw toward the head of the screw draws the flexible terminal from the extended position toward the retracted position.

A fastening system has a conditioner clamp and a penetrating fastener. The conditioner clamp has an upper assembly and a lower assembly attachable together to define a conductor cavity therebetween. At least one threaded opening provides ingress into the conductor cavity. The penetrating fastener is extendable through the at least one threaded opening. The penetrating fastener has a threaded bolt and a penetrating portion with a proximal end at a second end region of the threaded bolt and a distal end spaced therefrom. The penetrating portion has a frustoconical configuration terminating at a tip portion. The tip portion is configured to penetrate into a conductor positioned within the conductor cavity.

The present invention relates to a reusable mains-power electrical connector. The connector includes a connector body for receiving cables and fasteners. One or more protectors are located within the body to protect the received cables when the fasteners engage with the protectors to fasten the cables within the body. The connector also includes relieving means for relieving the cables of the protectors when releasing the fasteners to remove the cables. Advantageously, the connector may be re-used when the fasteners engage with the protectors to fasten new cables received within the body.

A meter box ground clamp may include a body portion having a first portion, a second portion, and a gripping portion that is configured to extend from the second portion and a fastener member configured to couple the body portion to an electrical meter box. The fastening member may be configured to extend through a receiving portion of the first portion to engage a first surface of the meter box so as to move the first portion away from the first surface of the meter box and move the gripping portion into engagement with a second surface of the meter box that faces away from the first surface of the meter box, and the receiving portion may be configured to receive the fastener member at a first angle less than 90 degrees relative to a plane of the first portion such that a free end of the fastener member forms a second angle greater than zero degrees relative to the second surface of the meter box. The second angle may be configured to create a force that urges the second portion of the body portion toward the meter box in response to a tightening torque applied to the fastener member so as to prevent the body portion from moving off the meter box in response to the tightening torque.

An electrical connection system includes a mounting stud having a base configured for mounting to a conductive surface. One or more one ring-shaped lugs, formed of an electrically conductive material, are configured for being positioned on the mounting stud for surrounding the mounting stud. The ring-shaped lug includes one or a plurality of interior channels extending around the inside diameter thereof. A contact spring is seated within a respective interior channel and is electrically conductive and dimensioned to extend radially inwardly from the channel and contact the mounting stud when the ring-shaped lug is positioned thereon. The contact spring is configured to at least partially collapse in the radial direction and to provide a spring bias against the mounting stud for providing an electrical connection between the ring-shaped lug and mounting stud. A locking cap is positioned on the mounting stud over the at least one ring-shaped lug for locking with the mounting stud and securing the ring-shaped lugs on the mounting stud for a secure electrical connection.

A contact assembly for a connector housing includes an adapter element and a contact element. The adapter element has a sleeve with a lead-through opening extending in an axial direction of the sleeve and with a threaded bore extending perpendicularly to the lead-through opening through the sleeve. The contact element is adapted to be inserted into the lead-through opening and latched to the sleeve. The contact element may exhibit varying types of a cable connection section and/or a contact section. The adapter element is receivable within the connector housing and may accept the contact element regardless of the type of cable connection section and/or contact section.
