This application claims the benefit of EP Application No. 09002547.9 filed Feb. 24, 2009, the entire contents of which are hereby incorporated by reference.
The present patent application relates to a holding device for a cable or an assembly like a trunk or furcation adapter for use with a cable.
In fiber optic communications networks, various types of holding devices are used to fasten a fiber optic cable or an assembly like a trunk or furcation adapter for use with a fiber optic cable to a supporting structure. The holding device can be mounted to the supporting structure, e.g. to a wall of a fiber optic distribution device like a connector housing, using some type of mounting means. When the holding device is mounted to a supporting structure there is no possibility for a revolution or rotation between the fiber optic cable and the supporting structure. Because of this, there is the risk of the optical fibers of the fiber optic cable being highly stressed or sustaining high tensions.
Against this background, a novel holding device for a cable or an assembly for use with a cable is provided reducing the risk of high stress and tensions in the cable.
This problem is solved by a holding device for a cable or an assembly for use with a cable according to claim 1. The holding device for a cable or an assembly for use with a cable comprises a cradle part adapted to hold the cable or the assembly for use with a cable; and a cover part to be mounted to a supporting structure, especially to a wall of a distribution device; whereby said cradle part when combined with said cover part can be rotated with respect to said cover part.
The holding device according to claim 1 allows a revolution or rotation between the cable and the supporting structure and reduces the risk of stress and tensions in the cable, especially in optical fibers of a fiber optic cable.
Preferred embodiments of the holding device are given in the dependent claims and the description below. Exemplary embodiments will be explained in more detail with reference to the drawing, in which:
The holding device 10 comprises a cradle part 11 to be mounted to the fiber optic cable or the assembly for use with the fiber optic cable and a cover part 12 to be mounted to a supporting structure (not shown), especially to a wall of a fiber optic distribution device like a distribution cabinet.
Said cradle part 11 when combined with said cover part 12 can be rotated with respect to said cover part 12. This allows a revolution or rotation between the fiber optic cable and the supporting structure when the holding device 10 receiving the fiber optic cable or the assembly for use with to the cable is mounted to the supporting structure.
The cradle part 11 of the holding device 10 comprises a cylindrically shaped outer wall 13. Said outer wall 13 of said cradle part 11 comprises a hinge 14 for pivoting a section 15 of the cylindrically shaped outer wall 13 against the other section 16 of the cylindrically shaped outer wall 13 in order to open or close an interior 17 of the cradle part 11.
A fiber optic cable or an assembly for use with the fiber optic cable can be inserted into said interior 17 of the cradle part 11 in radial direction of the cradle part 11 or its outer wall 13 when said interior 17 of the cradle part 11 is opened by said pivotable section 15 of the cylindrically shaped outer wall 13. The interior 17 of the cradle part 11 is defined by inner walls 18 of the cradle part 11 and has preferably a rectangular shape, although the cradle part 11 may be any shape.
The cover part 12 of the holding device 10 comprises also a cylindrically shaped outer wall 19. Said outer wall 19 of said cover part 12 comprises a hinge 20 for pivoting a section 21 of the cylindrically shaped outer wall 19 against the other section 22 of the cylindrically shaped outer wall 19 in order to open or close an interior 23 of the cover part 12. The interior 23 of the cover part 12 is defined by said outer wall 19 of and has a circular shape.
Said cradle part 11 of the holding device 10 can be inserted into said interior 23 of the cover part 12 of the holding device 10 in radial direction of the cover part 12 or its outer wall 19 when said interior of the cover part 12 is opened by said pivotable section 21 of the cylindrically shaped outer wall 19.
A locking device 24 formed by adjacent protrusions of the sections 21, 22 of the cylindrically shaped outer wall 19 allows for locking the cover part 12 of the holding device 10, especially when the cradle part 11 having a fiber optic cable or an assembly for use with a fiber optic cable is mounted into the interior 23 of the cover part 12.
The cradle part 11 of the holding device 10 comprises at least one arcuate shaped protrusion 25 extending outwardly from the cylindrically shaped outer wall 13. According to
The circumferential extension of the slot like recesses 26 define an angle sector which the cradle part 11 when combined with said cover part 12 can be rotated with respect to said cover part 11. This angle sector is preferably in the range of 90°. The circumferential extension of the slot like recesses 26 in circumferential direction of the cylindrically shaped outer wall 19 of the cover part 12 is of course larger than the circumferential extension of the arcuate shaped protrusion 25 in circumferential direction of the cylindrically shaped outer wall 13 of the cradle part 11.
The cylindrically shaped outer wall 19 of said cover part 12 is at least partly surrounding the cylindrically shaped outer wall 13 of said cradle part 11 when the cradle part 11 is combined with the cover part 12, namely mounted or inserted into the interior 23 of the cover part 12. Said cradle part 11 when combined with said cover part 12 can be rotated with respect to said cover part 12 around an axis running mostly in parallel to a longitudinal axis of said cylindrically shaped outer walls 13, 19.
The axis of rotation or revolution of the cradle part 11 with respect to said cover part 12 runs mostly in parallel to the linear axis of a fiber optic cable (not shown) attached to an assembly held by the holding device 10.
The cover part 12 of the holding device 10 comprises a recess 27 in which some type of mounting means may be inserted, whereby the cover part 12 and thereby the total holding device 10 can be mounted to a supporting structure through said component. US 2007/0047897 A1 shows such a component to be inserted into the recess 27 of the cover part 12 of the holding device 10 for mounting the holding device 10 to a supporting structure. It should be understood, though, that any type or form of mounting means may be used.
According the embodiment of
According the embodiment of
The holding device can be used for all types of cables like fiber optic cables, copper cables and hybrid cables.
