Abstract: A cable tray assembly for supporting cables, wires and the like. The assembly includes an elongate rail including an open channel extending along the length thereof. The assembly further includes at least one support member. Finally, the assembly includes a locking connector cooperating with the support member. The connector is sized and configured for insertion into the channel whereby insertion of the connector into the channel simultaneously locates the member at a position along the rail and fixedly secures the arm to the rail in the absence of fastening hardware.

Abstract: A modular telephone-style plug features a substantially three sided intermediate section which integrally connects the cable receiving end with the contact mating end of the plug. The intermediate section has an opening which spans virtually all of the fourth side of this section. The resultant three sided intermediate section provides for a reduced dielectric constant in the interior space in which the critical conductor transition from jacketed cable to contact termination occurs. This produces lower crosstalk and higher data propagation to allow this modular plug to be capable of a higher frequency for data transmission. The intermediate section features an expanded interior to lower crosstalk between twisted pairs of conductors over a wide range of data transmission rates. The intermediate section's expanded interior space permits greater freedom in the placement and relative positioning of any conductor pair to any other conductor pair.

Abstract: A connector comprises a header having a plurality of contacts mounted thereon in such a manner that the post portions thereof protrude outwardly, and a socket having mounted thereon a plurality of contacts for contacting with the respective post portions of the header and being electrically connected thereto. The socket further has a plurality of guide grooves for receiving the respective post portions of the header thereinto and guiding them to the corresponding contacts of the socket. The guide grooves form slots thin enough to be broken when receiving the post portions thereinto or sufficiently narrower than the width of the post portions. Those regions of the contacts of the socket which contact with the post portions are provided so as not to be exposed outwardly of the socket.

Abstract: A cover is employed with an edge mount electrical header connector to secure the header connector to a printed circuit board during soldering. The header connector includes plural electrical contacts supported in an insulative housing. The contacts include extending solder tails for engagement with solder pads of the printed circuit board. The cover includes an elongate insulative body for attachment to the header connector. The body of the cover includes gripper arms extending therefrom and being in spaced opposition to the extending solder tails. The solder tails and the gripper arms form a space therebetween for receiving an edge of the printed circuit board. The gripper arms and solder tails retain the printed circuit board edge so as to permit secure soldering of the solder tails to the solder pads of the printed circuit board.

Abstract: A cable tie includes an elongate generally planar strap and a head. The head includes a tapering entrance into a passageway therethrough for inserting the strap and a flexibly hinged locking pawl adjacent the passageway. The head also includes a fixed locking tooth adjacent the entry end of the passageway for engaging the strap after full securing an article or articles to be bundled. The fixed locking tooth of the present invention is desirably positioned to allow unobstructed insertion of the tail through the head. The present invention is able to minimize the stretching of the strap body when adjacent to the locking pawl by providing an edge which frictionally engages the strap body as the strap body egresses from the passageway of the head. Furthermore, the present invention may include a pair of counter-rotatable locking elements positioned to one side of the passageway through the head.

Abstract: A vibration-tolerant torque limiting fastening lug whereupon tightening of the set-screw produces a parasitic torque at the thread plane defining the set-screw/housing interface. The resultant parasitic torque acts in opposite direction to the installation torque such that the actual torque below the thread plane is less than the installation torque. As a result, the tensile force experienced by the set-screw and which acts against the housing of the lug is reduced.

Abstract: An electrical receptacle cover is securable over an electrical receptacle. The cover includes a generally planar cover plate for positioning over the receptacle. The cover plate includes an outlet opening therethrough for accessing the outlet of the electrical receptacle. The cover plate also includes an aperture therethrough for passage of a threaded fastening element. A threaded nut-like securement member is formed integrally with the planar cover plate. The securement member is frangibly removable so that it may be attached to the receptacle for accommodating the fastening element extending through the cover plate.

Abstract: A roadway luminaire is provided which includes a mast mount docking station securable to an end of a pole mast. The mast mount docking station includes a power plug electrically coupled to the power conductors. The luminaire includes a corresponding power plug which is electrically and mechanically coupled to the mast mount docking station via a twist-lock feature including mating keys and keyways in the docking station and luminaire, respectively. The luminaire includes several plug-in components such as a plug-in photoelectric cell, a plug-in starter and a capacitor press-fit into a molded cavity in the luminaire. The power plug of the luminaire is adaptable to be used with all international voltages. The twist-lock feature provides for a fool-proof mechanical and electrical connection to ensure that the correctly rated luminaire is connected to the supply voltage.

Abstract: The electrical connector assembly includes a female connector portion which is mountable to a first printed circuit board, such as a motherboard, and a male connector portion which is mechanically and electrically connected to a second printed circuit board, such as a daughterboard. The female connector portion includes a plurality of signal contacts arranged in two rows having a ground terminal, or conductive elastomer, positioned between the rows of signal contacts. The male connector portion preferably includes a flexible circuit having a solid groundplane separated by an dielectric insulator from an electrical trace thereon. The distance separating the groundplane from the trace and the width of the trace controls a characteristic impedance of the flexible circuit for matching to specific circuit requirements of the daughterboard and motherboard.

A wire contact assembly which is snapped into the connector housing and resiliently held therein by a releasable latch, comprises an insulation crimping portion that is formed during the crimping process to be of oval configuration. The oval configuration allows the use of wires at least as large as 28 AWG in such fine pitch spacings and permits installation of each wire contact assembly into the connector in the same orientation.

The palletizing package may also include protective liners placed between the shipping strap and the stack of cable trays to further protect the cable trays from damage by the cinched shipping strap.
