Abstract: A liquid-tight connector includes a threaded body, a finger/gland assembly within an annular pocket within the body, and a compression nut that engages a first threaded portion of the body. The finger/gland assembly includes a plurality of fingers attached to a sealing gland in an annular, collet-type fashion. The sealing gland and the fingers may be integral with one another. The sealing gland and the fingers may be co-molded with one another. Tightening the compression nut on the threaded body causes the compression nut to engage the fingers of the finger/gland assembly and bias the fingers toward each other. Such biasing causes the fingers to move inward and compress the sealing gland so that it forms a liquid-tight seal around the entire circumference of a cable within the body of the connector.

Abstract: An electrical connector system including first and second electrical connector members mated to one another to form a sealed connection in order to protect electrically-conductive components against the infiltration of moisture. The first connector member includes a socket with a first annular ridge at its tip, while a second annular ridge is formed within the socket at its base. An electrically-conductive pin is housed within the first connector member and extends into the interior of the socket. The second connector member includes a plug. An electrically-conductive socket, mated to the pin, is housed within the plug. When the plug of the second connector member is mated with the socket of the first connector member, the tip of the plug contacts the annular ridge at the base of the socket, which is deformed so as to form a water-tight seal between the tip of the plug and the base of the socket.

Abstract: A junction box for a photovoltaic system includes a housing having a base and a cover removably attached thereto, and a plurality of guide channels extending from an exterior surface of the housing to an interior portion thereof. The guide channels are sized and shaped to receive a plurality of conductive foil strips from a solar panel array. When the strips are fed into the guide channels, they are guided to and properly positioned within corresponding receptacles. Each receptacle is sized and shaped to receive a buss bar, and each strip is connected to a corresponding buss bar by a low insertion connector. When the cover is fully engaged with the base, bosses extending from the cover press against the connectors, creating a spring tension and pinch and retain the associated strip. As a result, a reliable physical and electrical connection between the strips and the buss bars is achieved. A heat sink having a plurality of fins protrude outwardly from the housing to dissipate heat externally.

Abstract: A panel-mounted electrical connector pair (12,36) has a recessed electrical connector (12) having a socket portion (18) with a first flange (26) proximate an open end (20) thereof, a first distal web (22) and a first type of electrical terminal (24a) protruding through said first distal web (22). The socket portion (18) is extendable through a first opening (64) in a first panel (62), with the first flange (26) abutting against the first panel (62). The connector pair (12, 36) includes a protruding connector (36) with a plug portion (38). The protruding connector (36) has a proximal end plate (42), a second distal web (44) spaced from the proximal end plate (42), a second flange (48) disposed on the protruding connector (36) proximate to the second distal web (44), and a second type of electrical terminal (46a) protruding through the second distal web (44) toward the proximal end plate (42). The proximal end plate (42) has an opening (94a) therein aligned with the second type of electrical terminal (46a).

Abstract: A premold for a powercord includes a housing which is provided with a network of walls and partitions that form channels and cavities adapted to securely receive a plurality of busbar stampings, each having multiple female contacts. Each busbar stamping has a crossbar, a plurality of female contacts and a wire crimp extension which extends outwardly from a rear wall of the housing for connection by crimping to a corresponding wire of a power supply cable. A front wall of the housing includes a plurality of outlet sites, each of which is adapted to receive a male electrical plug.

Abstract: A conductor bridge for holding a plurality of electrically conductive elements includes a monolithic body formed from an electrically non-conductive material. Retainer means are provided for retaining the electrically conductive elements in the body such that they are electrically insulated relative to each other. The retainer means has an open position, in which the conductor elements can be placed in the retainer means, and a closed position, in which the conductor elements can be held in place within the body.
