Cross-Reference to Related Application(s)
This application claims priority to U.S. Patent Application Serial No. 61/872,321 filed on August 30, 2013, the disclosure of which is incorporated herein by reference in its entirety.
Technical Field
The present invention relates to cable fixation devices and methods for fixing cables, such as to telecommunications equipment or other structures.
Background of the Invention
There is a need with telecommunications equipment to fix a cable entering or exiting the equipment. The cable is secured from pull forces so as to not disrupt the cabling or elements inside the equipment. The equipment can include a variety of telecommunications functions including one or more of: splicing, splitting, multiplexing, termination, storage, as examples. Improvements in cable fixation are desired.
Summary of the Invention
One aspect of the present invention includes a cable fixation device including a base. The base defines two outer cable pathways and an inner pathway for receiving one cable or a plurality of cables. The inner pathway defines inclined surfaces which cooperate with a movable wedge to clamp to the strength member or members of the cables and/or to a cable jacket. The wedge is moveable in two directions to accommodate strength members and/or jackets of different sizes to achieve clamping.
In one example embodiment, two different kinds of cables can be fixed, such as feeder cables and drop cables. The moveable wedge can clamp to both cables in the cable fixation device. In other examples, the same kinds of cables can be clamped on opposite sides of the wedge.
Another aspect of the present invention relates to a cable fixation device with a first cable pathway, a first clamping finger, and a movable wedge. The first clamping finger and the moveable wedge define inclined surfaces that face one another. The inclined surface of the first clamping finger is on an opposite side to the first cable pathway. The wedge is moveable in two directions to accommodate strength members and/or jackets of different sizes to achieve clamping. One or more cables can be clamped by the cable fixation device.
In a further aspect, a second clamping finger is provided, and a second side of the wedge is used to clamp to another cable or cables.

Detailed Description
Referring now to FIGS. 1 and 2, an example telecommunications equipment 10 is shown. Equipment 10 includes a splice area 12 and two cable fixation devices 14, one on each end 20, 22. Equipment 10 includes a base 16 and a cover 18. At one end 20, equipment 10 includes two cable pathways 24, 26 for cables to enter or exit equipment 10. At an opposite end 22, equipment 10 includes two cable pathways 28, 30 for cables to enter or exit equipment 10.
Equipment 10 allows for receipt of multiple cables from ends 20, 22 which can be spliced within equipment 10. Equipment 10 is just one example of equipment usable with a cable fixation device 14 on each end 20, 22, as will be described below. Equipment 10 can include other functions, such as splitting, multiplexing, terminations, or storage. Further, cable pathways 24, 26, 28, 30 can be located as desired in equipment 10. Equipment 10 can include more or less cable fixation devices 14.
Fixation devices 14 in the illustrated embodiment allow for fixation of one or more cables at each end of equipment 10. In the illustrated example of equipment 10, two fixation devices 14 are provided, one on each end 20, 22. Fixation device 14 allows for two cables to enter, one in each adjacent cable pathway 24, 26 or cable pathway 28, 30 for clamping. More cables of the same kind can enter each cable pathway 24, 26, 28, 30 and can be clamped by the fixation device 14.
Referring also to FIGS. 3-7, each cable fixation device 14 includes an inner pathway 40 positioned between cable pathways 24, 26. Each fixation device 14 defines a longitudinal axis 34. As shown, cable pathways 24, 26 are generally parallel to the longitudinal axis 34. Two clamping fingers 42, 44 allow for a portion of the cable to be wrapped around and clamped by a clamp 46. Clamp 46 includes a wedge 48 with outside surfaces 50, 52. Outside surfaces 50, 52 of wedge 48 face inside surfaces 60, 62 of inner pathway 40 defined by surfaces on clamping fingers 42, 44.
Wedge 48 is attached to base 16 with a fastener 70. Wedge 48 includes a slot 72 which is sized so as to allow movement of wedge 48 in two directions, an X direction 74 which is parallel to inner pathway 40, and a Y direction 76 which is transverse to inner pathway 40. Wedge 48 is movable in two directions to accommodate different thicknesses of the elements to be clamped. Fastener 70 fastens to base 16 and is loosened to allow movement of wedge 48 during set up, installation of additional cables, or adjustment.
With equipment 10, two sets of cables can be spliced in splice area 12. A cable in first cable pathway 24 can be spliced to a cable in third cable pathway 28. Further a cable in second cable pathway 26 can be spliced to a cable in fourth cable pathway 30. Other variations of cabling are possible. Wedge 48 of the fixation device 14 at each end 20, 22 can clamp to two cables at the same time.
Referring now to FIG. 8, a first cable 100 is shown held by the cable fixation device 14. First cable 100 is in first cable pathway 24, a first outer jacket 102 is held by a foam wrap 80 and a tie 82 which is received in tab 84 to mount first cable 100 to base 16. Tie 82 is received tab 84 including two holes. An inner jacket 104 continues into equipment 10. One or more fibers 106 extend from inner jacket 104, such as for splicing. A strength member 108 in the form of aramid yarn is wrapped around clamping finger 42 and clamped by wedge 48 and first clamping finger 42.
Referring now to FIG. 9, a second cable 110 is positioned in second cable pathway 26. Second cable 110 is held by a foam wrap 80 and a tie 82 affixed to tab 84. A first outer jacket portion 112 is wrapped around second clamping finger 44. A second outer jacket portion 114 is removed exposing one or more fibers 118 which continue on into equipment 10. A strength member 116 is positioned in first outer jacket portion 112. First outer jacket portion 112 and internal strength member 116 are wrapped around clamping finger 42 and clamped by wedge 48 and second clamping finger 44.
Referring now to FIG. 10, a plurality of second cables 110 are held by cable fixation device 14. Cables 110 are stacked one on top of each other and are held by wedge 48.
Second cable 110 is in the form of a butterfly style cable with two jacket portions 112, 114, each with an internal strength member or members on opposite sides of a central inner passageway containing one or more optical fibers. The middle of the cable has a thinner dimension than the two outer portions containing the strength members. Other cables besides the example cables 100, 110 can be held by fixation device 14.
FIG. 11 shows cable fixation device 14 clamping one first cable 100 and four second cables 110. Space savings is realized by having one device clamp more than one cable.
FIG. 12 shows an alternative embodiment for cable fixation device 14'. Alternative first clamping finger 142 and alternative second clamping finger 144 have inclined surfaces 160, 162 in an opposite direction to the inclined surfaces 50, 52 of first and second clamping fingers 42, 44. Alternative wedge 148 with outside surfaces 150,
152 is also positioned in an opposite direction to wedge 48. Wedge 148 may act to further tighten against the cable strength members and/or jackets in the event of a pull force being exerted on the cable or cables. In the above examples, two different kinds of cables can be fixed, such as feeder cables 100 and drop cables 110. The moveable wedge 48 can clamp to both cables in the cable fixation device 14. The portions of the cables being clamped have different dimensions. The moveable wedge 48 adapts to these variations. In other examples, the same kinds of cables can be clamped on opposite sides of the wedge. Plural cables of the same kind can be held on either side of the wedge 48 (See FIG. 11).
Device 14 is useable with one cable, two or more cables on the same side of the wedge 48, and one or more cables on opposite sides of the wedge 48 at the same time.
Tie 82 along with foam 80 is one example cable attachment device for attaching to an outer jacket of the cables 100, 110. Other clamping and attachment devices can be used if desired.
The above specification, examples and data provide a complete description of the manufacture and use of the composition of the invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
