  • the present invention relates to wall-mounted modular connectors for connecting communications, computing, entertainment, or other equipment and systems into a network installed in a building or other structure and, more particularly, a modular networking adapter for ensuring compatibility between equipment and networks installed in buildings.
  • telecommunications and the information superhighway has resulted in a need for multiple telecommunication interconnections in offices and homes.
  • a standard office usually required only a single communication wall connector, such as a telephone jack, between a worker and the outside world.
  • the increased use of audiovisual equipment, computers, facsimile machines, and cable equipment for communication has significantly increased the requirement for network cable connections.
  • a single worker may have equipment that requires multiple telecommunication cable connections, such as a computer network coupling, a modem coupling, a telephone coupling, fiber optic cable coupling, and a coaxial cable connection.
  • Communication cables including electric wiring, optical fibers, and coaxial cables, are typically routed through an office or house in surface mounted conduits, or within the walls, floors, and ceilings.
  • all the cabling runs horizontally, but in buildings with multiple floors, the cabling runs both vertically and horizontally: vertical cables run between floors, and horizontal cables branch out on a single floor.
  • the vertical and horizontal cabling usually come together on each floor in a central communications or telecommunications closet.
  • Each horizontal cable originates in the telecommunications closet and terminates at a connection member, such as, but not limited to, an optical fiber adapter, a phone jack, or an electrical connector.
  • the respective connection member is adapted to be operatively coupled to a connection member of selected telecommunications equipment within the office or house.
  • the present invention is a modular network adapter used to connect computer or other equipment to a network built into a building such as a house or office.

  • the circuit board has attached thereto a network connector that emerges through an aperture in the rear cover of the carrier module, and application connectors that emerge through the front cover of the carrier module.
  • the front cover is designed to position the application connectors at an angle that ensures ease of access and use in operation.
  • the construction of the carrier module in the embodiment meets the required architectural and electronic standard that the application-specific electronics not be a permanent part of the horizontal cabling; in other words, the application- specific electronics are external to the cabling.
  • the embodiment presents several advantages and provides a convenient way of ensuring compatibility between a network and equipment connected thereto.
  • the modular construction of the embodiment provides an easily exchangeable module that allows rapid adaptation to changing technology standards.
  • the construction of the carrier module also is such that the application connectors are easily accessible, the module is easily insertable in and removable from the wall plate, and the entire module is easily accessible, insertable and removable by the user from the front of the wall plate without removing the wall plate.

  • the bars 20 are sized and positioned to each having the rearward faces thereof engaged by corresponding pairs of left and right side resilient tabs 22 of the carrier module 16 when in position against the forward faces of the bars to removably secure the carrier module to the wall plate 14.
  • the wall plate 14 may be sized for use with a single width wall box or may have more than one aperture 18 to simultaneously receive more than one carrier module 16 in side- by-side relation.
  • the wall plate 14 has four fastener holes 15 through which threaded fasteners 17 are inserted to be threadably received in threaded holes 21 in the electrical box 13 to attach the wall plate flush against the wall 12.
  • the wall plate 14 is attached to the electrical box 13 with the aperture 18 of the wall plate aligned with the opening of the electrical box.

  • the rear cover 30 is securely attached to the front cover 24 using a threaded fastener 31 which extends through a fastener hole 32 in the rear cover and is threadably received in a hole 33 in a boss 29 formed at the interior side 28 of the front cover.
  • the carrier module 16 is releasably held in the aperture 18 of the wall plate 14 by the tabs 22 engaging the bars 20.

  • the lower face 37 has the two apertures 38 therein in which the application connectors 52 of the circuit board 50 are positioned (see Figure 4), thereby providing downwardly facing connectors.
  • the upper face 36 may have printed indicia thereon (not shown), for example corporate logos, text indicating the kind of circuit board 50 contained within the carrier module 16, text indicating the type of signal interface performed by the circuit board, or other information.
  • the upper face 36 and lower face 37 form selected angles with respect to the planar portion 35 of the front cover 24 and with respect to each other.
  • the angles of the upper face 36 and lower face 37 relative to the planar portion 35 are chosen to provide a visible surface to the user to facilitate reading any printed indicia on the upper surface and convenient access by the user for inserting the connector of the cable 11 into the downward facing application connectors 52 so as to have the cable 11 extending downward therefrom without severe bending required.
  • the circuit board 50 which is desirably positioned substantially perpendicular to the lower face 37, and which uses conventional application connectors 52, will fit within the interior compartment of the carrier module 16 and the carrier module will fit within the electrical box 13 when the carrier module is positioned in the aperture 18 of the wall plate 14.
