Definitions

  • the technological field of the disclosure is electrical power distribution and, in particular, the distribution of electrical power for convenient, temporary use.
  • the type of electrical power needed has also expanded and includes alternating current and direct current as well as different levels of voltage.
  • portable generators may be employed to generate electrical power for, say, construction sites, emergency roadside conditions, or outdoor events, but the delivery of that power relies on electrical cords laying on the ground or perhaps raised off the ground to be slung from one temporary post to the next.
  • the present disclosure presents a structural system for delivering electrical
  • the system is based on pairs of universal electrical connectors connected to each other by electrical wires and carried inside a section of conduit.
  • Conduit sections can be formed as tubes joined to other conduit sections or has half cylinders for more easily receiving electrical wires and then the half cylinders can be joined.
  • the electrical connectors inside the conduit are those described in copending and commonly owned US patent application serial number 15/063948 for a Magnetic Repulsion-Based Electrical Connector, which is incorporated by reference herein in its entirety.
  • the electrical connectors in the present disclosure operate essentially as disclosed and described in this related application.
  • two spaced-apart electrical connectors are joined to each other by electrical wiring in a manner generally similar to an extension cord with one electrical connector on one end and another electrical connector on the other end. Both electrical connectors are positioned inside the same conduit section.
  • a first electrical connector is recessed within a first end of a first conduit section and a second electrical connector is mounted flush in the second end of the first conduit section.
  • the second electrical connector of the second conduit section is inserted into the first end of the first conduit section so that the second electrical connector of the second conduit section is inside and adjacent to the recessed first electrical connector of the first conduit section. If the second electrical connector of the second conduit section is oriented toward the first electrical connector of the first conduit section, their first terminals will be automatically aligned with the non-movable terminals using the magnetic repulsion which will result in the non-movable terminals moving away from each other and toward the movable terminals.
  • the magnet surrounding the movable terminal of each is oriented the same way so movable terminals will repel and movable and non-movable terminals will make contact.
  • the correct magnetic terminals of each electrical connector will be pulled and held partially outside of their respective passages and into the passages of the recessed ferromagnetic non-movable terminals, which produces the electrical connection and preserves parity.
  • the movement of the movable terminal into the passage of the recessed non-movable terminal also prevents lateral forces from easily separating the electrically connected terminals. Because the electrical terminals move with each other, locked together, vibrations and small movements due to traffic across the conduits will not cause power interruptions, arcing, and flickering lights.
  • Conduit sections can be standardized and available in sets of straight and curved or angled conduit sections. Accordingly, conduit sections can be selected to form nearly any structural configuration.
  • a universal conduit section is provided in which a first end can be rotated for changes in direction from one section to another where more flexibility is needed than available from a selection of angled conduit sections.
  • Conduit sections with a cylindrical interior passage can have an external appearance that is not cylindrical and have an appearance unrelated to the electrical connectors and wiring inside.
  • the external appearance of conduit sections may even be ornamental, such as wainscot molding, or simply for serving as trim for another structure (such as trim pieces on the edges of modular panels), and carry the electrical connectors inside for transferring electric power.
  • Joined conduit sections can also serve as stand-alone structures having a primary purpose other than delivering electrical current, such as velvet rope for use at events, but can be conveniently used to deliver electrical current in a discrete and convenient way for lighting, for example.
  • Conduit sections may also be used to deliver digital data and messages via carrier waves.
  • the conduit sections may have a primary purpose, in the sense of an
  • the conduit section may be load-bearing as support beams for a patio.
  • the conduit sections may form a barrier that informs the public about a boundary, such as a safety barricade, a fence rail or construction barrier, while also conveniently delivering electrical power to flood lights, a gate lock or a gate intercom.
  • the electrical connectors may also carry additional electrical contacts or contact pins for use in establishing an electrical connection between remote conduit sections with their electrical connectors.
  • a contact pin in a remote electrical connector may verify that the electrical contacts of the terminals have been properly made throughout each intervening electrical connector, or determine if a break in connection occurs, and where the break occurred.
  • the contacts can also deliver electricity of a different type such as low voltage DC, or transmit information in the form of voice or digital data.
  • conduit sections may carry additional electrical wiring for electrical circuits in parallel to the primary electrical power wiring to provide the capability to make management of the network easier, such as control signals, digital data transmission, identification information, and administrative information.
  • wiring running in parallel to the primary electrical power wiring may carry voice communication from one end of a construction site to another or digital programming signals to permit control of security systems for a building.
