Abstract: Examples disclosed herein illustrate various implementations of access ports that are to be mounted to various types of electrical enclosures. In some implementations, the access ports are circular to provide ease of installation and to reduce the overall footprint of the access ports.

Abstract: Implementations include a compartmentalized plug-in load center having connector receptacles for load circuit wiring connection to the load center and a plug-in back plate to connect the plug-in load center to a vertical power busway within a utility wall panel of a building, and a method for installing the load center in a building with a vertical power busway.

Abstract: An electrical busway plug-in unit includes a pair of restraint mechanisms extending through the housing of the plug-in unit for mechanically attaching the plug-in unit to the busway. Each restraint mechanism includes a rotatable shaft extending through the front wall of the housing, and a knob attached to the front end of the shaft, on the exterior side of the front wall of the housing, for manually rotating the shaft. A mechanical connector projects rearwardly from the rear wall of the housing and extends forwardly into the interior of the housing where the connector is coupled to the shaft so that rotational movement of the shaft in opposite directions moves the connector into and out of latching engagement with the busway.

Abstract: A flush mounted assembly for housing an electronic or electro-mechanical module which detects abnormal conditions and responds to the detection of such abnormal conditions. The assembly includes a base mounted in an opening in a structural member such as a wall, partition or ceiling. The base includes a peripheral wall defining a shallow cavity with an outer open face and an inner wall. A laterally outwardly projecting flange extends from the peripheral side wall of the base for flush engagement with the structural member. The shallow cavity of the base is dimensioned to receive the electronic or electro-mechanical module. A closure plate is provided for the open outer face of the base. The closure face has a periphery dimensioned to close the open outer face of the shallow cavity in the base leaving only a narrow gap between the closure plate periphery and the base periphery wall to allow ambient air to enter the shallow cavity of the base and interact with the module.

Abstract: An adapter suitable for installation in a machine in place of a customer replaceable unit monitor having a first interface format is described herein. Upon installation of the adapter in the machine, the adapter enables data communication between the machine and a customer replaceable unit monitor having a second interface format that is different than the first interface format. The first and second interface formats may include one or more of: configuration of an electrical interface of the customer replaceable unit monitor, configuration of a mechanical interface of the customer replaceable unit monitor, and configuration of data input to and output from the customer replaceable unit monitor. The adapter may be attached to a module before the module is installed in the machine to simplify installation of the adapter.

Abstract: The plugging device of the present invention provides a pair of sticks similar to the blades of a scissor on top of the connector of the plugging device. The pair of sticks is closed together when they are plugged into a network socket along with the connector. Then, by twisting a knob of the plugging device behind the connector, the two sticks are opened so that the hooks at the front ends of the sticks lock to the network socket for reliable connection. To unplug, the knob is twisted in a reversed direction and the two sticks are closed together again so that they are free to be pulled out of the network socket along with the connector.

Abstract: A connector includes a housing, and a flange portion which is formed by extending one main surface of the housing in a direction that a first circuit board is inserted. An adapter includes a casing having an insertion port into which a cartridge for first game machine can be inserted, and having a shape capable of being inserted into an insertion port of a second game machine. An adapter circuit board is contained in the casing, and includes a data conversion circuit which converts first game machine data stored in the cartridge for first game machine into data capable of being utilized in the second game machine.

Abstract: A PGA connector includes: a shuttle plate slidably engageable on a socket base having a plurality of sockets recessed in the base, and a plurality of contact elements each contact element embedded in each socket in the socket base, the shuttle plate integrally formed with at least one resilient lever on a side plate portion longitudinally formed on a side portion of the shuttle plate and slidably resiliently urging a positioning lug formed on a side wall of the socket base, whereby upon forwardly sliding of the shuttle plate having an electronic package of pin grid arrays (PGA) mounted on the shuttle plate with the PGA leads pre-inserted into the sockets in the base by passing through a plurality of lead holes formed in the shuttle plate to keep an insertable buffer distance between each contact element and each lead, the positioning lug on the socket base will be engageably locked by a detention hook portion formed on a rear portion of the resilient lever for firmly engaging each PGA lead with each contact e

Abstract: Apparatus for distributing electic current, especially in a low voltage track lighting system includes: (i) a cable in the form of a rigid rod having coaxial conductors and male and female couplings at its opposite ends allowing the cable rod to be connected end-to-end with other similar cable rods, and the inner conductor having a spring loaded contact at one end; (ii) a coupling unit which may be used to connect rotatably one cable rod to another cable rod or an appliance, the unit having relatively rotatable housing parts defining respective male couplings at the opposite ends of the unit, and contacts arranged to project axially at the opposite ends, the contacts being connected by a flexible braided conductor and urged apart by a coil spring; and (iii) a coupling including a track with a channel having a connector carried by an inner wall and side walls with inturned flanges, a connector (which may be a cable rod or coupling unit) with a screw threaded end through which a contact projects, and a nut whic

Abstract: A bracket for an electrical connector is disclosed wherein the bracket has a body defining an opening to accommodate a portion of the electrical connector and to which is fixedly attached a plurality of stud members. The stud members each have a head portion extending from one side of the bracket body, the head portion defining an internally threaded hole to accept a mounting or a holddown screw to attach the electrical connector portion to the bracket. Each stud member also has a threaded stud portion extending from an opposite side of the bracket body. These studs may be attached to a panel or to another connector by placing nuts or the like over the threaded stud portions.

Abstract: A device preventing connector pins attached to individual wires in a conductor from becoming removed from a computer connector. The device includes a body, which defines a chamber and includes a top, a bottom and sides joining the top and bottom. The computer connector is secured to the bottom of the body by a connecting apparatus and the conductor is secured to the body by a strain relief mechanism. The device prevents the connector pins from becoming removed from the computer connector when moving the conductor after the strain relief member has secured the conductor to the body and the connecting apparatus has secured the computer connector to the body.

Abstract: An electrical terminal includes first and second members having elongated complementary arcuate surfaces thereon movable toward and away from each other by a clamping member. The second member is pivotally supported at one end on the first member and is configured so that different diameter conductors can be securely clamped between the arcuate surfaces.
