A junction box mountable on a roof surface, comprising a housing unit and an enclosing unit, the housing unit and enclosing unit combining to form a waterproof assembly. The housing unit is mountable to a roof surface via a flashing having a continuous, raised waterproofing track that mates with a waterproofing recess in a bottom surface of the housing unit to create a waterproofing zone inside the housing unit. At least one bottom pass through is located within the waterproofing zone and provides a channel from the internal housing area through the roof surface.

An electrical box assembly and cable connector are provided. The cable connector includes a connector housing and a cable retaining member that releasably secures an electrical cable within the connector housing. The electrical box assembly includes an electrical box and a cable connector. The electrical box assembly may also include a box separator.

A sealing system for an electronics enclosure includes an enclosure having a first enclosure half and a second enclosure half, the first enclosure half including at least one sidewall, a multi-lip radial sealing member having a plurality of lip elements, the lip elements extending perpendicularly to the side wall, the radial sealing member being positioned between the first enclosure half and the second enclosure half such that the radial sealing member remains flush against the enclosure, and the lip elements form continuous points of contact around the perimeter of the enclosure.

The present disclosure provides descriptions of electrical box assemblies for supporting heavy fixtures, such as ceiling fans, and facilitating electrical connections to the fixtures. The electrical box assembly includes an electrical box that allows a connection between the box and electrical conduits and a connection, e.g., a weatherproof connection, with a housing of the fixture. The box has an open front face to house electrical connections between the fixture and wires supplying electrical power to the box via the conduits. The box has a bottom wall and an open front face. A reinforcement member fits within the electrical box and includes a panel shaped to conform to at least a portion of the bottom wall and one or more standoffs extending toward the open front face of the box. When the reinforcement member is positioned within the box, mounting holes in the bottom wall of the box and reinforcement member are aligned to allow the box to be attached to a building structure.

An electrical box including a central housing with a first side opening, a second side opening opposite the first side opening, and a rear opening, each of the first and second side openings configured to receive an electrical or data interface device, a first extension compartment around the first side opening, the first extension compartment including a first door, a second extension compartment around the second side opening, the second extension compartment including a second door, and an exterior cover extending at least partially over the central housing, the first extension compartment, and the second extension compartment.

An electrical coupler comprising a housing with an end opening, an insulation block arranged in the end opening, a lid having an open position and a closed position, an arm attached to the lid and to the housing, whereby attachment of the arm to the housing allows a rotation of the arm relative to the housing around a rotational axis, and optionally a series of arms connected to each other to allow one arm to rotate relative to a neighbouring arm. The lid further comprises a housing contact surface that contacts or is in close proximity to a lid contact surface of the housing, a reference line through the point of the lid contact surface furthest away from the base plane, and wherein a part of the housing contact surface crosses a reference plane closer to the base plane than the reference line is, as the lid is moved from the closed to the open position.

An electrical connection assembly includes an electrical box including a housing having an internal surface defining an internal volume of the housing. An electrical connector is positioned outside the internal volume of the housing and fixed to the housing with a fastener. The housing includes an aperture having an opening defining an insertion path extending from a location external to the housing along a frame of the electrical connector to a location within the internal volume of the housing. The assembly includes a disc mechanically secured to the housing relative to the opening to obstruct the insertion path. A retainer and a bushing including a membrane for the electrical connector as well as methods of making an electrical connector are also provided.

Embodiments of the present disclosure provide an opening and closing mechanism and a leakage protection device. The opening and closing mechanism comprises: a stationary contact and a movable contact, which contacts the stationary contact at ON-position and separates from the stationary contact at OFF-position; a first magnetic assembly; and a second magnetic assembly that is integrally rotatable about an axis, the second magnetic assembly comprising: an electric conductor onto which the movable contact is mounted; and a magnetic body comprising at least one magnetic portion configured to rotate about the axis under a magnetic force from the first magnetic assembly, to correspondingly drive the movable contact to rotate between the ON-position and the OFF-position, wherein a distance from each of the at least one magnetic portion to the axis is smaller than a distance from the movable contact to the axis. In accordance with embodiments of the present disclosure, the transmission efficiency within the opening and closing mechanism may be boosted, and the movable and stationary contacts are separated faster and by a longer distance, so as to improve the performance of the opening and closing mechanism.

An electrical cable assembly, comprising a first electrical circuit further comprising a first plurality of insulated conductors longitudinally disposed to one another, wherein the first plurality of insulated conductors are cabled together in a bundle. The electrical cable assembly further comprises a second electrical circuit longitudinally disposed to the first electrical circuit, the second electrical circuit comprising a second plurality of insulated conductors longitudinally disposed to one another and cabled together in a bundle and a nonmetallic jacket surrounding the second plurality of insulated conductors and wherein the nonmetallic jacket isolating the first electrical circuit from the second electrical circuit. The electrical cable assembly further comprises a flexible interlocking metallic armor encasing the first and second electrical circuits.

An access control device for permitting access to a coaxial cable component while selectively blocking access to a fiber optical component including an access control panel member configured to be coupled to a coaxial cable component while blocking access to a fiber optical component, the coaxial cable component configured to be coupled to a coaxial cable and an optical fiber configuration base member configured to be coupled to an optical fiber component and to arrange the optical fiber component so as to create a peripheral optical fiber cable path around a portion of the optical fiber component.
