- the poke-through fitting includes many components that are the same as or similar to components described U.S. Patent Application Serial No. 09/201 ,492 (the "'492 application) which was filed on November 30, 1998 and is entitled "Improved Poke-through
- the poke-through fitting 10 is adapted to be installed in a fire-rated floor A of a building, such as a commercial office building. More specifically, the poke-through fitting 10 may be installed in a circular opening B formed in floor A to activate a desired floor location. It is adapted to be activated by connecting source power service and source signal service cables, which are otherwise disposed in the plenum C below the floor A, to fittings such as power receptacles and data jacks, respectively, mounted internally in the poke-through fitting 10. This enables above-floor A power plugs and signal transferring devices to be connected the poke-through fitting 10 and to thus transfer power and communication/data signals to equipment located on or above the floor A.
- the poke-through fitting 10 comprises an insert 12 that is adapted to be installed in a floor opening B.
- Insert 12 includes an upper, generally cylindrical chamber 14, which is generally defined at the insert's upper end by a horizontally disposed top plate 16 and at its lower end by a horizontally disposed middle plate 18. (In the illustrated embodiment, the top plate 16 is generally defined by the finishing ring 82 and power receptacle support plates 300).
- a data housing 20 divides the upper chamber 14 into a central space or portion 24 in which the communication/data connectors 32 are disposed, and pair of radially outer, semi-annular side spaces or portions 26 in which the power receptacles 28 are disposed.
- the fitting 10 includes four power receptacles 28 that are adapted to be activated within the fitting 10 by high-voltage power cables 30 within the housing.
- the power receptacles 28 may be wired in a single circuit or may be wired in a two electrically isolated circuits.
- the receptacles 28 are wired in two electrically isolated circuits. Specifically, the two receptacles in the left side space (in Figure 2) are wired in one circuit, while the receptacles in the right side space are wired in a second circuit.
- the fitting 10 also internally supports a plurality (four in the illustrated embodiment) of low-voltage service connectors or jacks 32 that are adapted to be activated within the fitting 10 by low-voltage source signal service cables 34.
- These jacks 32 are generally referred to herein as communication/data jacks. Terminals in the upper faces of the communication/data jacks 32 are accessible through sliders in the cover plate 84.
- the fitting 10 includes two RJ- 45 category 5 jacks 36 and two fiber optic jacks 38. (See Figure 4). Terminals in the lower ends of the jacks 32 are positioned in the data housing 20 where they are interconnected with the cables 34.
- the data housing 20 physically separates and electrically isolates the connection between the power receptacles 28 and the source power service cables 30 from the connection between the communication/data jacks 32 and the source signal service cables 34 so as to shield the source signal service cables, and their associated jacks 32, from E.M.I, and/or R.F.I, emanating from the source power service cables 30.
- the data housing 20 is generally rectangular and includes a bottom wall 40, a pair of opposed side walls 42, a pair of opposed end walls 44, and a top opening 46 which define the central space 24.
- the side walls 42 extend across the chamber like chords and serve to divide the central space 24 from the side spaces 26.
- the data housing 20 shields the central space 24, where the low- voltage services cables 34 are connected to the communication/data jacks 32, from the radially outer spaces 26, where the high-voltage power cables 30 are connected to the power receptacles 28.
- the data housing 20 is preferably made from two interlocking half-sections 48a, 48b. Interlocking fingers 51 formed on the top edges of the end walls 44 help secure the sections 48a, 48b together. (See Figure 7) Openings 50 are formed in the bottom wall 40 for routing communication/data cables 34 into the central space 24.
- Flanges 52 extend from the bottom wall around the openings 50. The flange 52 engage in reciprocal openings 54 (see Figure 6) in the middle plate 18 to further secure the housing sections 48a, 48b together.
- the data housing 20 is comprised of a dielectric material such as polyvinyl chloride.
- an E.M.I/R.F.I, shield 58 is disposed about the data housing 20.
- the shield 58 is in the form of a two-piece metal jacket 65 which is configured to snap around the exterior of the data housing 20. (See Figure 7).
- the metal jacket 65 ensures compliance with local building codes that preclude exposed plastic housings.
- the metal jacket 65 also helps secure the housing sections 48a, 48b together. In some applications it may be economically desirable to replace the metal jacket with a foil collector, as is described in the '492 application and the '126 patent.
- Mounting flanges 56 extend from the bottom edges of the side walls 42.
- the metal jacket has flanges 59 that align with the mounting flanges 56.
- Metallic fasteners 61 such as screws, extend through apertures in the flanges 56, 59 and thread into reciprocal apertures in the middle plate to secure the data housing 20 to the plate 18. (See Figures 3 and 6. Note that in Figure 3, the conductors have been shown in broken line so that the connection between the housing 20 and plate 18 can be seen). This connection also serves to ground the shield 58 to drain E.M.I, and R.F.I which is generated in the chamber 14.
- the shield 58 is grounded through the fasteners 61 to the middle plate 18, and in turn through a metallic fastener 60, such as a rivet or bolt, to a horizontally disposed bottom plate 62 which is in turn grounded through conventional electrical metalized tubing (EMT) 64.
- EMT electrical metalized tubing
- Insert 12 further includes two fire stopping elements 66, comprised intumescent material such as hydrated sodium silicate.
- the elements 66 form an insulating barrier to control temperature increases and retard the spread of flames.
- the elements 66 further protect against heat and flame by forming a refractory char as the temperature continues to rise.
- the fire stopping elements 66 each include a central, hollow passage
- the elements 66 similarly include two side hollow passages 70 that define two side raceways through which the communication/data signal service cables 34 are extendable. (See Figure 4)
- the fire stopping elements 66 are supported between the middle plate 18 and the bottom plate 62.
- the middle and bottom plates 18, 62 have openings which are aligned with the passages 68, 70 in the elements 66 to permit wires to pass between the plenum C and the upper chamber 14.
- the upper end of the electrical metalized tubing 64 is connected to the bottom plate 62 for securing a conduit system thereto and for improving grounding capability.
- a conventional junction box 74 may be connected to the lower end of the tube 64.
- Insert 12 also includes a conventional annular retainer 76 which is disposed adjacent the middle plate 18.
- the retainer 76 retains the poke- through fitting 10 in floor opening B.
- the fasteners 60 extend between and are connected between the plates 18 and 62 for assisting in securing the fire stopping elements 66 between the plates, and as noted above, to facilitate grounding of the barrier EMI/RFI collector 58.
- the poke-through fitting 10 further includes a top assembly 80 which is connected with the upper end of the insert and which overlies the floor opening B.
- the top assembly 80 includes a carpet flange or finish ring 82 and a cover plate 84.
- the finishing ring 82 is secured to the insert 12 by fasteners (now shown) that extend through the finishing ring 82 and thread into reciprocal openings in legs 86 (see Figure 6) that extend upwardly from the middle plate 18. (Note that in Figure 6 the front leg 86 is drawn in broken line so that the top of plate 18 can be seen more clearly).
- the finishing ring 82 has a central opening 83 that overlies the upper chamber 14 of the insert to provide access therefor.
- the cover plate 84 is generally circular and is sized to fit in a generally annular recess 90 formed in the top of the finish ring 82 around the central opening 83. Threaded fasteners 85 secure the cover plate 84 to the finish ring 82. (See, e.g. Figure 2).
- the cover plate 84 includes four power covers 92 that are positioned to overlay the side spaces 26 and hence the power receptacles 28. Slots 94 in the covers 92 are alignable with corresponding blade receiving slots in the power receptacle 28.
- the covers 92 may be moved outwardly so that outlet slots 94 in the covers 92 align with corresponding slots in the power receptacle 28, to permit an electrical plug (not shown) to be connected to the receptacle 28 for activation of above floor A power services.
- the cover plate 84 also has four communication/data jack covers or sliders 100 that are positioned to overlay the central space 24 of the chamber 14.
- the covers 100 are slidably movable between positions covering and uncovering the associated communication/data jacks 32.
- the communication/data covers 100 are constructed such that any of the communication/data jacks are covered (protected) when they are not in use.
- the covers 100 include a pair of lower, inner covers 102 and a pair of upper, outer covers 104.
- the lower covers 102 are slidably mounted in lower grooves formed in the cover plate 84, whereas the upper covers 104 are mounted in upper grooves in the cover plate.
- Each covers 102, 104 can be moved outwardly to expose the underlying communication/data jack independently of the other sliders 102, 104.
- the data housing 20 is configured to support communication/data jacks at either a flush mount position (left half of Figure 8A) or recessed position (right half of Figure 8A).
- the data housing 20 includes an upper ribs or flanges 202 formed on the inside of each of the end walls 44 and lower ribs or flanges 204 formed on the end walls and the side walls.
- the lower flanges 204 on the side walls align generally with vertical slots 206 in the side walls.
- the data housing 20 further includes a vertical divider 208 that slidably engages in the vertical slots 206.
- a recessed mounting bracket 210 is provided for mounting a pair of communication/data connectors, such as co-axial connectors, in a recessed fashion.
- the top wall 212 of the bracket 210 overlies and is supported by the lower flanges 204.
- the recessed mounting bracket 210 is installed prior to the vertical divider 208.
- a flush mounting bracket 216 is provided for mounting a pair of communication/data jacks, such as RJ-45 Category 5 jacks, in a flush mount fashion.
- the flush mount bracket 216 is adapted to be supported in the housing at its outer end by the upper flange 202 and at its inner end by the top edge of the central divider 208.
- Locking tabs 218 are provided for locking the mounting bracket into the housing.
- the locking tabs 218 are biased inwardly by the top flange 202 and the divider 208. Once the outer locking tab 218 moves downwardly beyond the top flange 202 it snaps outwardly to secure the upper flange between the tab 218 and the top wall 220 of the bracket. Similarly, the inner locking tab is configured to snap into a reciprocal opening 219 or slot formed in the vertical divider 208. Once installed, the top wall 220 of the flush mount bracket 216 is generally flush with the top wall of the data housing 20. Depending on the application, any combination of the mounting brackets 210, 216 may be used.
- the flush mounting bracket 216 is generally similar to the bracket second portion 202A shown in Figure 4 and described in detail on pages 13 to 16 of the '492 application. As is noted in the '492 application, this component is commercially available from Interlink division of the Wiremold Company as a model 2A-U2 KEY connector, and is constructed to support a pair of Keystone data jacks that are also commercially available from Interlink. Similarly, the recess mounting bracket generally corresponds to the bracket second portion 202B which is shown in Figure 5 and described in detail on pages 16 to 17 of the '492 application. It will be appreciated that other mounting brackets may readily be used to support communication/data connectors of differing constructions. Moreover, a single mounting bracket could be provided for supporting four communication/data receptacles within the housing 20.
- the poke-through 10 includes a pair of receptacle mounting brackets 300 that are adapted to slidably engage with the side walls of the data housing 20.
- the mounting brackets 300 are formed of metal.
- Each of the receptacle mounting brackets 300 has a top plate 302 and a downwardly extending side plate 304.
- the side plates 304 are configured to slidably engage with flanges 306 formed in the side walls 42 of the data housing 20 to secure the receptacle mounting brackets thereto.
- the electrical receptacles 28 are in the form of simplex receptacles which are configured to snap into mounting apertures 308 formed in the top plate 302 of the power receptacle mounting brackets 300.
- the housing of the power receptacle 28 includes a pair of opposing locking tabs 310 that extend outwardly from the housing.
- the mounting bracket top plate 302 is compressed between the locking tabs 310 and the top wall 312 of the receptacle 28 when the receptacle is inserted into the bracket 300. In use, the mounting brackets are not removable from the fitting once it is installed in the floor.
- the four power receptacles 28 are connected in dual, isolated circuits.
- six power source conductor cables/wires are fed into the fitting through the EMT 64.
- each circuit includes a neutral conductor 30a, a line conductor 30b, and a ground conductor 30c.
- the receptacles may all be wired on a single circuit by branching feed wires from a single set of power supply wires.
- the conductors for a given circuit extend upwardly through the conduit 64 and are routed into one of the side spaces 26 of the chamber 14 through a wiring tunnel 320 formed in the bottom of the data housing 20. (See Figures 3, 5 and 6).
- the power connectors fit into grooves or slots 322 formed in the bottom of the power receptacles. As the wires are pushed into the slots 322, the insulation on the wires is abraded by terminals in the power receptacles, thereby completing the circuit between the source cables 30 and the power receptacles 28.
- Stuffer caps 324 are used to force the power cables into the terminals and connection slots 322 in the bottom of the receptacles. The stuffer caps 324 snap onto the bottoms of the receptacles 28.
- the power receptacles 28 in a given pair are positioned such that they face in opposite directions. More specifically, they are mounted with their ground slots facing each other. As a result, the line and neutral slots in the two associated power receptacles do not align with each other. Hence, for a given pair of power receptacles, the line and neutral cables must criss-cross at the transition between the two power receptacles.
- the cover plate 84 includes a pair of outer recess 400 and a central recess 404.
- the outer recesses 400 are positioned to overlay the side spaces 26 and the central recess 404 is positioned to overlay the central space 24.
- Each of the outer recesses 400 is configured to carry two of the power covers 92.
- each of the recesses 400 is divided into a first portion 406 which carries a first cover 92a and a second portion 408 which carries a second cover 92b. These portions are generally delineated by a transverse support flange 410.
- the first and second covers 92a, 92b and the first and second recessed portions 406, 408 are mirror images of one another, respectively. Hence, only one cover and one recessed portion will be described. Specifically, installation of the left most cover 92a (in Figure 15) cover 92a into the first portion 406 of the recess 400 will be described.
- the cover 92a has an outwardly extending flange 412 formed along a portion the lower end of its outer edge. This outwardly extending flange 412 is configured to slidably engage in a horizontal groove 414 formed in the outer edge of the recess 400.
- the cover 92a also includes a bent leg 416 extending from its bottom along a portion of its inner edge. This bent leg 416 is configured to slidably engage with a reciprocal bent leg 418 formed along a portion of the inner edge of the recess.
- the spring has a first leg 424 that engages against the body of the cover plate and a second leg 426 that is positioned to engage against a spring post 428 that extends downwardly from the slider cover 92a.
- the spring post 428 engages against the second leg 426 of the spring 420, thereby compressing the spring 420.
- a slot 430 is formed in the recess so as to slidably receive the spring post 428 (see Figure 17). The interface between the spring post 428 and the outer end of the slot 430 functions as a stop to limit outward travel of the slider 92.
- the cover 92a is installed by initially tilting the outer edge downward and inserting the outer flange 412 into the reciprocal groove 414. The cover 92a is then moved inwardly (in the direction opposite the arrow 425) until its bent leg 416 is positioned inwardly of the bent leg 418 in the recess. At this position, the spring post 428 is also positioned inwardly of the spring 420. The inner edge of the cover 92a is pivoted downward (in the direction of the arrow 434) until the cover is seated in the recess.
- the cover 92a is then slid outwardly (in the direction of arrow 425) until the bent leg 416 on the cover moves past a flange on notch 436 formed on the bent leg 418, thereby locking the cover 92a in place.
- the interface between the notch 436 and the bent leg 416 also serves to limit inward movement (i.e., opposite arrow 425) of the cover 92a.
- the second cover 92b is installed in the same manner, except that the first cover 92a must be slid outwardly to provide clearance for the second cover 92b during its installation.
- the four communication/data sliders or covers 100 are divided into first pair of covers, e.g., the two left cover 100 in Figure 10, and a second pair of covers, e.g., the two right covers 100 in Figure 10.
- the first pair of covers 100 are mounted in a first portion 504 of the central recess 404 and the second pair of covers are mounted in a second portion 506 of the recess 404.
- the first and second portions 504, 506 of the recess are delineated by a transverse flange 508 that also serves as an inner stop for the inner covers 102.
- Each pair of covers includes a first or outer cover 104 that is slidably connected to the cover plate along a first generally horizontal plane 510.
- the outer cover includes outwardly extending flanges 514 that are configured to slidably engage with a reciprocal set of upper grooves 516 formed in the outer edges of the central recess.
- Each pair of covers also includes a second or inner cover 102 slidably that is connected to the cover plate along a second generally horizontal plane 512 that is different from the first plane 510.
- the inner cover includes outwardly extending flanges 520 that are configured to slidably engage with a reciprocal set of lower grooves 522 formed in the outer edges of the central recess.
- the inner cover slides in a plane that is below outer cover, such that the inner cover can be slid underneath the outer cover.
- the covers 102, 104 are installed into the cover plate by first sliding the inner cover 102 into the lower set of grooves 522. Inward travel of the inner cover 102 is limited by the transverse flange 508. The outer cover 104 is then slid into the upper set of grooves 516. Tabs 530 (see Figure 10) formed on the outer edges of the flanges 514 lock the outer cover 104 into the grooves 516.
