No. 61/640,435, filed Apr. 30, 2012, entitled "PAYOUT SPOOL WITH AUTOMATIC CABLE DISCONNECT/RECONNECT," the disclosures of which are hereby incorporated herein by reference in their entireties.
[0002] Spools or reels can be used to store telecommunications cable (e.g., electrical cable and/or fiber optic cable). The spools include a hub or a drum about which the cable is wound. The hub of the spools is often cylindrical, and the cable is often wrapped around the cylindrical hub in a predominantly circumferential manner. By winding up the cable on the spool, the cable can be compactly stored and transported, protected from tangling and kinking, and kept ready for easy deployment.
[0003] An aspect of the present disclosure relates to a payout spool for a telecommunications cable. The telecommunications cable extends between a first end and a second end. The payout spool pays out the telecommunications cable when the first end of the telecommunications cable is pulled away from the payout spool. The payout spool includes a base, a spool, and a disconnect/reconnect device. The base includes a terminal for transmitting and/or receiving a telecommunication signal to and/or from the telecommunications cable. The spool is rotatably mounted to the base about an axis. The spool is adapted to unwrap the telecommunications cable about a wrapping area of the spool when the spool is rotated about the axis. The disconnect/reconnect device is adapted to disconnect the second end of the telecommunications cable from the terminal when the payout spool pays out the telecommunications cable.

[0053] Reference will now be made in detail to the exemplary aspects of the present disclosure that are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like structure. In certain instances, parts and features are shown schematically and the reference numbers may be followed by an "s" to indicate this.
[0054] According to the principals of the present disclosure, a spool assembly is adapted to pay-out and reel-in a telecommunications cable. The spool assembly can pay-out and reel-in extended lengths of the telecommunications cable without manually disconnecting and connecting the telecommunications cable from a base end. In particular, a paid-out end can be pulled from the spool assembly at various lengths including the extended lengths to bring the paid-out end of the telecommunications cable to a desired location. The spool assembly does not require a rotary union or substantial accumulated twist in the telecommunications cable, but rather a connection of the spool assembly is disconnected while the spool assembly is paying-out or reeling-in the telecommunications cable. In particular, when the spool assembly begins paying-out or reeling-in the telecommunications cable, the connection is disconnected thereby freeing a portion of the telecommunications cable that is wrapped around the spool assembly from being constrained by the base end. Upon the telecommunications cable being paid-out or reeled-in, as desired, the connection is reconnected thereby allowing the paid-out end of the telecommunications cable to communicate with the base end.
[0055] Turning now to FIGS. 1-12, a spool assembly 100, according to the principles of the present disclosure, is schematically illustrated. In particular, FIGS. 1-4 schematically illustrate a spool assembly 100a, FIGS. 5-8 schematically illustrate a spool assembly 100r, and FIGS. 9-12 schematically illustrate a spool assembly 100t. The spool assemblies 100a, 100r, and 100t each include a telecommunications cable 80 (e.g., a fiber optic cable) that includes a first end 82. The first end 82 may be connectorized by a connector 90 (e.g., a fiber optic connector). The first end 82 and/or the connector 90 can be pulled from the spool assembly 100, 100a, 100r, 100t and extended to a desired location (i.e., paid-out). Likewise, the first end 82 and/or the connector 90 can be reeled-in by the spool assembly 100, 100a, 100r, 100t and positioned as desired (i.e., retracted).
[0056] As depicted, the spool assembly 100, 100a, 100r, 100t also includes a terminal 290. As depicted, the terminal 290 is not substantially extendable from the spool assembly 100, 100a, 100r, 100t. As depicted, the terminal 290 does not rotate with a spool 150 of the spool assembly 100, 100a, 100r, 100t, but is generally stationary with a mount 200 of the spool assembly 100, 100a, 100r, 100t. In certain embodiments, the terminal 290 may be fixed with the mount 200. As depicted, the terminal 290 is attached to the mount 200 by a cable 280 (i.e., a base cable). In particular, a first end 282 of the cable 280 is attached to the terminal 290. As depicted, the terminal 290 can be a fiber optic connector. In other embodiments, the terminal 290 can be a fiber optic adaptor. The terminal 290 can be permanently or semi-permanently connected to a fiber optic component, a fiber optic network, etc. If it is desired to change the position of the first end 82 and/or the connector 90, the terminal 290 can remain connected to the fiber optic component, the fiber optic network, etc.
[0057] To accommodate the first end 82 and/or the connector 90 changing position, particularly when the change in position results in a difference in length between the terminal 290 and the first end 82 and/or the connector 90, the terminal 290 is disconnected from the telecommunications cable 80, thereby allowing the spool 150 to spin and pay-out or reel-in the telecommunications cable 80.
[0058] In the depicted embodiment, the telecommunications cable 80 extends between the first end 82 and a second end 84, and the cable 280 extends between the first end 282 and a second end 284. The second end 84 and the second end 284 meet each other at a disconnect/reconnect device 300. As illustrated at FIGS. 1-4, the disconnect/reconnect device 300 is an axial disconnect/reconnect device 300a, as illustrated at FIGS. 5-8, the disconnect/reconnect device 300 is a radial disconnect/reconnect device 300r, and as illustrated at FIGS. 9-12, the disconnect/reconnect device 300 is a tangential disconnect/reconnect device 300t. In each of the illustrated embodiments, the disconnect/reconnect device 300, 300a, 300r, 300t facilitates the connection, disconnection, and reconnection of the second end 84 and the second end 284. In particular, as illustrated at FIGS. 1, 6, 9, and 10, the second end 284 and the second end 84 are connected (e.g., optically connected). As illustrated at FIGS. 3, 8, 11, and 12, the second end 284 and the second end 84 are disconnected (i.e., optically disconnected). In preferred embodiments, the spool 150 actuates the disconnect/reconnect device 300, 300a, 300r, 300t to connect, disconnect, and reconnect the second end 284 and the second end 84.
[0059] As illustrated at FIGS. 1, 3, 5, 7, 9, 11, 13, and 27-29, the spool 150 includes a spool body 160. The spool body 160 extends between a first side 162 and a second side 164. A first flange 172 may be positioned at the first side 162, and a second flange 174 may be positioned at the second side 164. A cylindrical surface 176 may extend between the first flange 172 and the second flange 174. A wrapping area 170 may be included on the cylinder 176. The wrapping area 170 may serve as a surface to wrap and unwrap the telecommunications cable 80 from the spool 150. The telecommunications cable 80 may be wrapped and unwrapped from the wrapping area 170 a single layer deep or multiple layers deep. By wrapping the telecommunications cable 80 on the wrapping area 170, substantial lengths of the telecommunications cable 80 may be stored on the spool 150. A significant portion of the length of the telecommunications cable 80 wrapped about the wrapping area 170 may be deployed (i.e., extended from the spool 150) when it is desired that the first end 82 and/or the connector 90 be positioned a significant distance away from the terminal 290.
[0060] The telecommunications cable 80 thereby includes a wrapped portion 88 that is wrapped about the wrapping area 170. The telecommunications cable 80 further includes a deployed portion 89 that extends between the wrapping area 170 and the first end 82 when the first end 82 is spaced from the wrapping area 170. As depicted, the telecommunications cable 80 also includes a wind-up portion 86 that accommodates a limited amount of rotational movement between the spool 150 and the mount 200. The wind-up portion 86 thereby accommodates the rotational movement of the spool 150 that may be required to actuate the disconnect/reconnect device 300, 300a, 300r, 300t. In the depicted embodiment, the wind-up portion 86 is positioned within a coiling area 180. As depicted, the coiling area 180 is positioned within the cylindrical surface 176 of the spool 150 (see FIG. 2).
[0061] In the depicted embodiments, the wind-up portion 86 and the wrapped portion 88 meet each other and transition between each other at an opening 178. In the depicted embodiment, the opening 178 is positioned on the wrapping area 170. The telecommunications cable 80 may be fixed to the opening 178, or the telecommunications cable 80 may slip through the opening 178.
[0062] In the depicted embodiments, the spool 150 includes a hub 190. The hub 190 is rotatably mounted to the mount 200 thereby allowing the spool 150 to spin about the mount 200. As depicted, a first part 302, 302a, 302r, 302t of the disconnect/reconnect device 300, 300a, 300r, 300t is attached to the hub 190 of the spool 150. A second part 304, 304a, 304r, 304t is attached to the mount 200.
[0063] When the spool 150 rotates, the mount 200 generally remains stationary. Therefore, the first part 302, 302a, 302r, 302t generally rotates with the spool 150 and the second part 304, 304a, 304r, 304t generally remains stationary with the mount 200. However, the first part 302, 302a, 302r, 302t may slide with respect to the hub 190, and the second part 304, 304a, 304r, 304t may slide relative to the mount 200. This sliding action may be used when actuating the disconnect/reconnect device 300, 300a, 300r, 300t.
[0064] In the depicted embodiments, the disconnect/reconnect device 300, 300a, 300r, 300t may remain initially connected when the spool 150 begins to rotate relative to the mount 200. Likewise, the disconnect/reconnect device 300, 300a, 300r, 300t may remain connected during initial rotational movements between the spool 150 and the mount 200. In this situation, the first part 302, 302a, 302r, 302t does not initially rotate with the spool 150. Rotation of the spool 150 may actuate the disconnect/reconnect device 300, 300a, 300r, 300t. Upon the disconnect/reconnect device 300, 300a, 300r, 300t disconnecting the first part 302, 302a, 302r, 302t from the second part 304, 304a, 304r, 304t, the second part 304, 304a, 304r, 304t is free to rotate with the spool 150. The first part 302, 302a, 302r, 302t generally holds the second end 84 of the telecommunications cable 80, and the second part 304, 304a, 304r, 304t generally holds the second end 284 of the cable 280.
[0065] Turning now to FIGS. 13-26, an example embodiment of the spool assembly 100 is illustrated. As illustrated at FIG. 13, the terminal 290 of the spool assembly 100 may be directly mounted to the mount 200. Or, the cable 280 may be connected to the second part 304 of the disconnect/reconnect device 300 and the terminal 290 may be remotely connected via the first end 282 of the cable 280. As illustrated at FIG. 14, the second part 304 of the disconnect/reconnect device 300 may be directly mounted to the mount 200. In the embodiment depicted at FIGS. 13-26, the disconnect/reconnect device 300 generally has an axial movement and therefore is an example embodiment of the axial disconnect/reconnect device 300a.
[0066] In the depicted embodiment of FIGS. 13-26, the spool 150 includes the spool body 160 with the first side 162 and the second side 164. The first flange 172 is positioned at the first side 162, and the second flange 174 is positioned at the second side 164. The cylindrical surface 176 extends between the first flange 172 and the second flange 174. A shaft 192 extends from the hub 190. The shaft 192 includes a bearing 194 and a thrust bearing 196. The bearing 194 and/or the thrust bearing 196 may engage the mount 200. In particular, the bearing 194 may provide rotational support for the spool 150, and the thrust bearing 196 may provide axial (i.e., thrust) support for the spool 150. The shaft 192 further includes a thread 198 (see FIGS. 27-29) and an assembly channel 199.
[0067] In the embodiment depicted at FIGS. 13-26, the mount 200 includes a first piece 220 and a second piece 250. As depicted, the first piece 220 and the second piece 250 are split about a hole 202 of the mount 200. In other embodiments, the mount 200 can be a single piece mount. The mount 200 includes a bearing 293 and a thrust bearing 295 (see FIGS. 39, 43, and 46). The mount 200 further includes a thrust surface 260 (see FIGS. 44 and 46). The mount 200 further includes a first engagement feature 270 and a second engagement feature 272 (see FIGS. 36, 38, and 42). The mount 200 further includes a mount 281 for the second part 304 of the disconnect/reconnect device 300 (see FIGS. 36, 38, and 42). As depicted, the mount 200 may include mounting holes. The mounting holes may also be used to join the first piece 220 to the second piece 250. The first piece 220 may include a half-hole 222 and the second piece 250 may include a half-hole 252. The half-hole 222 and the half-hole 252 may together define the hole 202. The mount 200 may further include a slide 291. The slide 291 may have a first side 292 and a second side 294 (see FIGS. 36 and 38). A first guide feature 296 may transition into the first side 292, and a second guide feature 298 may transition into the second side 294.
[0068] The embodiment illustrated at FIGS. 13-26 includes an actuating member 400 (see FIGS. 30-35). The actuating member 400 includes a bearing surface 402 (e.g. a hole). A thread engaging feature 404 may be positioned within the bearing surface 402. The actuating member 400 may further include a mount 420 for mounting the first part 302 of the disconnect/reconnect device 300. In the depicted embodiment, the mount 420 is adapted to mount an SC connector, as shown. In particular, the mount 420 is adapted to mount a release sleeve of the SC connector. The actuating member 400 further includes a guide 440. In the depicted embodiment, the guide 440 includes parallel sides and is generally shaped like a channel. In the depicted embodiment the guide 440 further includes a spring seat 460. The spring seat 460 may include a centering feature for centering a spring.
[0069] A general description of an example assembly sequence will now be given for the spool assembly 100, as depicted at FIGS. 13-26. A spring 500 may be positioned and mounted at the hub 190 of the spool 150, as illustrated at FIG. 14. A shield 600 may be positioned over the spring 500 and also mounted to the hub 190. The actuating member 400 may be mounted over the shaft 192 of the spool 150. In particular, the thread engaging feature 404 is aligned with the assembly channel 199 of the shaft 192. This allows the actuating member 400 to be axially slid along the shaft 192 until the thread engaging feature 404 reaches the thread 198 of the shaft 192. The actuating member 400 may further be assembled onto the shaft 192 by screwing the actuating member 400 onto the shaft 192. In particular, the thread engaging feature 404 engages the thread 198 and thereby couples the rotational and axial relative movements between the actuating member 400 and the spool 150 according to a thread pitch of the thread 198. The thread pitch of the thread 198 may be a constant thread pitch or may be a variable thread pitch. The first part 302 may now be assembled into the mount 420. In the depicted embodiment, the first part 302 includes a fiber optic connector. In particular, as illustrated at FIG. 22, the first part 302 includes an SC fiber optic connector. The first part 302 mounts the second end 84 of the telecommunications cable 80. In the depicted embodiment, the SC fiber optic connector terminates the second end 84 of the telecommunications cable 80. Thus, the second end 84 is terminated with a ferrule (e.g. a ceramic ferrule). Furthermore, the second end 284 of the telecommunications cable 280 may also be terminated with a ferrule (e.g. a ceramic ferrule). The disconnect/reconnect device 300 may thereby use ferrules at the connection point.
[0070] After the actuating member 400 is assembled to the first part 302 of the disconnect/reconnect device 300 and properly positioned along the shaft 192 of the spool 150, the shaft 192 may be mounted to the mount 200. In the depicted embodiment, the actuating member 400 preferably compresses the spring 500 when the actuating member 400 is positioned along the shaft 192 at a position that allows the shaft 192 to be assembled to the mount 200.
[0071] The second part 304 of the disconnect/reconnect device 300 may be preassembled into the mount 200. In particular, in the depicted embodiment a fiber optic adapter forms a part of the second part 304 of the disconnect/reconnect device 300. The second part 304 is mounted in the mount 281 of the mount 200, as depicted at FIG. 22.
[0072] The shaft 192 may be assembled into the hole 202 of the mount 200. The bearing 194 of the shaft 192 is supported by the bearing 293 of the mount 200. The thrust bearing 196 of the shaft 192 is supported by the thrust bearing 295 of the mount 200. As illustrated at FIGS. 14 and 22, a spring 700 may be positioned between the spool 150 and the mount 200. In the depicted embodiment the spring 700 is illustrated schematically. The spring 700 may be a coil spring, a torsion spring, or other type of spring. The spring 700 may urge the spool 150 to rotate in a given rotational direction. The spring 700 may resist the first end 82 of the telecommunications cable 80 from being pulled off of the spool 150. The spring 700 may retract or may assist in the retraction of the telecommunications cable 80 when the telecommunications cable 80 is wound onto the spool 150. The wind-up portion 86 of the telecommunications cable 80 may be positioned in the coiling area 180 as illustrated at FIG. 14. The telecommunications cable 80 may be threaded through a hole 177 in the hub 190 before threading through the hole 178 that extends through the cylindrical surface 176. The wrapped portion 88 of the telecommunications cable 80 is wrapped about the cylindrical surface 176.
[0073] A description will now be given of the operation of the spool assembly 100, as illustrated at FIGS. 13-26. FIGS. 13 and 14 show the spool assembly 100 with the disconnect/reconnect device 300 connecting the second end 84 with the second end 284. Alternatively, the embodiment of FIGS. 13 and 14 shows the spool assembly 100 with the second end 84 connected to the second part 304. Upon rotation of the spool 150 in a rotational direction 902 (see FIG. 15), the actuating member 400 is pulled in a direction 904 by the thread engaging feature 404 engaging the thread 198. This movement of the actuating member 400 in the direction 904 compresses the spring 500 and moves a release sleeve 802 of a fiber optic connector 800 (see FIG. 16). As illustrated by the changes between FIGS. 24 and 25, the movement of the release sleeve 802 results in latches 852 of a fiber optic adapter 850 being released from a catch 804 of the fiber optic connector 800. By having a latching system make the connection between the first part 302 and the second part 304, a connection similar to or the same as a connection between a pair of the fiber optic connectors 800, when connected by the fiber optic adapter 850, can be realized. Upon the latches 852 releasing the fiber optic connector 800 from the fiber optic adapter 850, the fiber optic connector 800 connected to the first part 302 may be further moved to an axial position where the fiber optic connector 800 and the first part 302 clear the fiber optic adapter 850, as illustrated at FIGS. 17, 18, and 26.
[0074] The continued axial movement is provided by the actuating member 400. In particular, the guide 440 is guided along the slide 291 as the actuating member 400 is urged by the rotation of the spool 150. The rotation of the spool 150 during this axial translation portion of the movement is not accompanied by rotation of the first part 302. Instead, the wind-up portion 86 of the telecommunications cable 80 accommodates the relative rotation. The shield 600 keeps the wind-up portion 86 of the telecommunications cable 80 free from the spring 500. Upon the guide 440 reaching the end of the slide 291, the first part 302 of the disconnect/reconnect device 300 is free to rotate about the axis Al. The spring 500 may provide a torsional component that catches the first part 302 up rotationally with the spool 150. The thrust surface 260 may engage the actuating member 400 and thereby keep the actuating member 400 from being moved back toward the connected configuration. In particular, the thrust surface 260 may keep the actuating member 400 axially extended while the spool 150 is rotating and thereby paying-out or reeling-in the telecommunications cable 80.
[0075] As the telecommunications cable 80 is disconnected from the terminal 290, continued rotation of the spool 150 to pay-out additional length of the deployed portion 89 do not result in accumulated twist or wind up of the telecommunications cable 80. Thus, the rotation of the spool 150 is limited only by the storage capacity of the spool 150 for the telecommunications cable 80. The spring 700 may provide tension to the deployed portion 89 of the telecommunications cable 80.
[0076] Upon the first end 82 and/or the connector 90 reaching a desired position, the spool 150 is allowed to move into a position such that the guide 440 aligns with the slide 291. In certain embodiments, this alignment may be achieved by slowly rotating the spool 150 as the spring 500 applies a load between the actuating member 400 and the thrust surface 260. A clicking or pulse indication along the telecommunications cable 80 may indicate that the guide 440 is aligned with the slide 291.
[0077] The guide 440 may include transitional features (e.g., chamfers) that further assist in aligning the guide 440 with the slide 291. In addition, the first engagement feature 270 and the second engagement feature 272 may engage the guide 440 to facilitate the return of the disconnect/reconnect device 300 to the connected configuration. Upon the guide 440 engaging the slide 291, the telecommunications cable 80 may be slightly retracted onto the spool 150 (e.g., by the spring 700). The rotation, opposite from the rotation 902, allows the actuating member 400 to slide away from the disconnected configuration and toward the connected configuration. The latches 852 of the fiber optic adapter 850 will allow the fiber optic connector 800 to be reinserted into the fiber optic adapter 850 and thereby connect with the fiber optic adapter 850. Upon the reconnection of the fiber optic connector 800 with the fiber optic adapter 850, the telecommunications cable 80 is reconnected with the terminal 290. Thus, a signal can travel between the connector 90 and the terminal 290.
[0078] The process of retracting a substantial amount of the telecommunications cable 80 onto the spool 150 is substantially the same as the paying-out of the telecommunications cable 80. Upon retraction being desired, the first part 302 and the second part 304 of the disconnect/reconnect device 300 are disconnected by rotating the spool 150 to disengage the first part 302 from the second part 304 and move the first part 302 into the rotatable configuration (see FIG. 18). The spool 150 is then allowed to reverse rotation and retract a substantial amount of the telecommunications cable 80. In certain embodiments, allowing a rotation speed sufficient to keep the guide 440 from engaging the slide 291 will allow the spool 150 to continue retracting substantial amounts of the deployed portion 89 of the telecommunications cable 80. Upon a sufficient amount of the telecommunications cable 80 being retracted, the guide 440 and the slide 291 are aligned, similar to the process described above. Upon the guide 440 and the slide 291 being engaged, the actuating member 400 is allowed to move the first part 302 and the second part 304 into the connected configuration. Upon the second end 284 and the second end 84 being reconnected, the telecommunications cable 80 is again connected to the terminal 290.
[0079] Various modifications and alterations of this disclosure will become apparent to those skilled in the art without departing from the scope and spirit of this disclosure, and it should be understood that the scope of this disclosure is not to be unduly limited to the illustrative embodiments set forth herein.
