Abstract: An electrical connector includes a plug assembly and a mating connector assembly. Additional protection against liquid penetration of the assembled connector is provided by a peripheral tongue-in-groove seal formed in the integrally molded housings of the plug and connector assemblies.

Abstract: A portable fluorescent lamp fixture adapted for use with a plurality of fluorescent lamps includes an elongated center channel extending substantially the entire length of the fixture and disposed intermediate a pair of fluorescent lamps for providing a high strength, rugged structure. With a rubber end cap attached to each end of the center channel and a transparent protective tube comprised of polycarbonate or butyrate extending between the end caps and disposed about the center channel and fluorescent lamps, the lamp fixture is provided with a liquid-tight seal. The center channel includes an open lower portion along its length, having an inverted generally U-shaped cross-section, and is adapted to receive a removable snap-on cover along its entire length for enclosing lamp circuitry such as a ballast, a terminal block and wire leads. The removable cover facilitates access to lamp circuitry for maintenance.

Abstract: An apparatus for the in-line testing of a transducer including a connector module having a source port, an outlet port, and a test port. The source port is connected to a power source and the outlet port is connected to a transducer. A cap, coupled to the test port, allows for the transmission of power from the power source to the transucer. The transmission of power from the power source to the transducer may be interrupted by removing the cap from the test port. A conventional testing instrument may be connected to the test port for testing or calibration of the transducer once the cap has been removed from the test port.

Abstract: A lighted, quick-disconnect, right-angle molded electrical connector for connecting a control device or a sensor to a load includes a lens of light-transmissive material, covers a "power available" light source and a "power applied" light source and is arranged to have external viewing surfaces so that the indicators can readily be seen from substantially any normal viewing direction.

Abstract: An economical string light includes a molded socket or base having an integral hook for attaching to a messenger wire for support and first and second insulation-displacement connectors for coupling to the electrical power wires. The lamp guard is formed of two identical protector elements which have a coupling collar for connecting to each other and to a retainer flange on the socket. The protector elements are hinged from the coupling collar to open in a clamshell fashion to facilitate lamp replacement, and the protection elements couple together with snap couplers to form the complete lamp guard.

Abstract: An electrical fitting has a rigid tubular body in the form of an elbow with one connector insert rotatably received at one end of the body and a second connector insert fixed within the body in the other end. Insulated flexible wires within the body connect corresponding elements of the connector inserts. The fitting is particularly useful in establishing a quick disconnect for machines or instruments from a flexible feed cord while avoiding a "gooseneck" in the feed cord.

Abstract: A power distribution center for use at marinas, trailor camps and the like includes a housing adapted to receive power feed cable from an external power source, the cables being connected to terminal blocks mounted within the housing and to which are connected terminals of electrical receptacles mounted within the housing. The housing includes a cover which when opened provides access to the receptacles. A light source including a diffusing lens mounted within the upper portion of the housing is effective to illuminate the front portion of the housing both when the cover is closed and when it is opened. The housing and cover are of a corrosion resistant synthetic material, and internal metallic brackets and plates which mount the terminals, receptacles and light source are electrically connected to the ground terminal which provides a unitized ground on a single ground lug.
