摘要： A ninety degree electrical fitting for connecting electrical cable to an electrical box. The ninety degree electrical fitting includes a connector body with a leading end and a trailing end, a snap ring connected to the leading end, and a clip member connected to the trailing end. A leading flange and a box engagement flange on the leading end of the connector body define a means for retaining the snap ring on the connector body. A clip member connected to the connector body provides a means for securing an electrical cable to the trailing end of the fitting. Internal walls on the connector body define an internal passageway having a wide turn radius, to enable wiring leads from an electrical cable to pass easily through the internal passageway of the connector body. The ninety degree snap fit electrical fitting provides good electrical continuity between the outer sheath of an electrical cable, the electrical box, and the fitting.

摘要： A cable tray assembly comprising a plurality of tray segments, each tray segment comprising a first portion and a second portion positioned about first and second ends, respectively, of the tray segment. The first portion has an inner region between at least sidewalls of the tray segment that is sized to receive placement of a second end of another tray segment. Additionally, the first portion can include one or more open ended grooves that, during assembly of the cable tray assembly, can receive a mating projection that is securely connected to the second end of the other tray segment. The open ended groove can be downwardly sloped, and can extend through an outer edge of the corresponding sidewall. The projection can be fixed or adjoined to the second end at least prior to assembly of the cable tray assembly, and can include shank that is threadingly engaged by a retainer.

摘要： 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.

摘要： A sealing device adapted for an object to be disposed through is provided. The sealing device includes a casing, a sealing elastic member, and a pressing member. The casing has an accommodating groove and a penetrating via communicated with the accommodating groove. The sealing elastic member is detachably disposed in the accommodating groove and has a through hole aligned with the penetrating via. The sealing elastic member is adapted to be compressed along an axis. The through hole has a first inner diameter before compression and a second inner diameter after compression. An outer dimension of the object is less than or equal to the first inner diameter and greater than the second inner diameter. The pressing member is detachably disposed at the casing and presses against the sealing elastic member, so that the compressed sealing elastic member is fixed in the accommodating groove.
