Definitions

  • Various cable spools and devices are known for storing slack loops of cables, such as fiber optic cables.
  • protection of the storage loops from sharp bends is important.
  • Retaining the cables so that the storage loops are maintained in an organized manner is also important.
  • Keeping the storage loops within the device over time is also important.
  • a cable storage device is provided with a base, a middle area for holding of one or more loops of fiber optic cable, and an outer periphery including at least one wall.
  • a cable retention device helps to retain the cables in the storage device.
  • Various other walls, tabs, and flanges may be provided to assist with cable retention.
  • the cable retention device preferably keeps the storage loop or loops retained in the cable storage device, such as during manipulation of other cables or from vibrations over time.
  • Figure 1 is a perspective view of a first implementation of a cable spool device
  • Figure 2 is a cross-sectional perspective view of the device of Figure 1 ;
  • Figure 3 is a cross-sectional side view of the device of Figure 1 ;
  • Figure 5 is a cross-sectional perspective view of the device of Figure 4;

  • Figure 8 is a cross-sectional side view of the device of Figure 7;

  • Figure 12 is a perspective view of a fourth implementation of a cable storage device
  • Figure 13 is a cross-sectional perspective view of the device of Figure 12.
  • Figure 14 is a cross-sectional side view of the device of Figure 12.
  • Figure 1 shows a cable storage device 10 including a base 12 and a middle support 14 for holding one or more loops of fiber optic cable around middle support 14. Extending upward from base 12 are one or more walls 16. Walls 16 are positioned around the outer periphery of device 10 in the example implementations. Flanges 18, 20 and walls 16 help to retain cables within an interior of device 10.
  • Flanges 18 extend inwardly from outer walls 16.
  • Flange 20 extends outwardly from middle support 14.
  • Base 12, walls 16 and flanges 18, 20 can have different shapes if desired to provide for cable retention.
  • Cable storage device 10 includes a cable retention device 30 which helps to further retain cables within device 10.
  • Various cable retention devices 30 are shown in the various figures.
  • the retention devices 30 are some examples of a retention device which makes it more difficult for fibers placed in device 10 to fall out of device 10 inadvertently, or come out at undesired times. Cables enter and exit at one or more openings 22. Cables are stored in one or more loops around middle support 14.
  • the retention device 30 is provided for the user to relatively easily place one or more loops of stored fiber optic cable in a protected area on a cable storage device 10.
  • Cable storage device 10 can be used to store small cables, such as 250 or 900 micron fibers, and relatively short lengths, such as 30-70 centimeters. Other cables and lengths can be used with device 10.
  • Retention device 30 makes it is relatively difficult for the one or more loops of fiber optic cables to fall out of cable storage device 10 when other fiber loops may be manipulated or moved, or during use and storage, such as due to vibrations.
  • Fiber optic cables tend to want to return to a straightened or elongated orientation after being placed in a storage loop. If the optical fiber can find its way out of the cable storage device 10, the cable is subject to possible damage or excessive bending.
  • cable storage device 110 includes a retention device 30 which includes a first portion 138 which extends toward outer wall 16 and one or more second portions 140 which extend inwardly from outer wall 16.
  • a channel or slot 144 is defined between first portion 138 and outer wall 16. By positioning second portions 140 on opposite sides of first portion 138, a torturous path of slot 144 is provided. A user can insert cables into slot 144 and the cables are retained in pocket 146.
  • cable storage device 210 includes a retention device 30 which includes a first portion 238 which extends toward a second portion 240.
  • Second portion 240 is in the form a u-shaped channel which is slidable and pivotable relative to a rest of device 210. Once second portion 240 is slid and pivoted, cables are positioned by the user in pocket 246. Second portion 240 is returned to the retention position as shown in Figures 7 and 8 for storage. Once in the retention position, no openings for fibers to fall out are provided.
  • cable storage device 310 includes retention device 30 which includes a first portion 338 which extends toward outer wall 16. First portion 338 includes a downwardly extending tab 340.
  • Tab 340 defines a channel or slot 344 with outer wall 16.
  • Slot 344 has a curved shape. Slot 344 is accessed outside of outer wall 16. A user can position cables in slot 344 for retention in pocket 346. Slot 344 has a shape that the fibers cannot easily go to without user assistance.
  • Protrusions 346 are provided on base 12 to move the cables away from slot 344 toward first portion 338.
  • cable retention device 30 is designed so as to not promote excessive bending as the user places or removes fibers. At the same time, cable retention device 30 promotes retention by preventing a fiber from coming out of the cable storage devices 10, 110, 210, 310 without user assistance. Other shapes and designs are possible to protect the fibers during manipulation and storage.
