Telecommunication cable strain relief assemblies
View Patent ↗A strain relief assembly includes a top plate and a bottom plate. The top plate defines a plurality of top ports configured to receive a plurality of cables at a first point. The bottom plate defines a plurality of bottom ports configured to receive the plurality of cables at a second point. The strain relief assembly is movable between an open position and a closed position. In the open position, the plurality of top ports and the plurality of bottom ports collectively define a first passage area. In the closed position, the plurality of top ports and the plurality of bottom ports collectively define a second passage area smaller than the first passage area.
1. A strain relief assembly comprising:
a top plate and a bottom plate, wherein
the top plate defines a plurality of top ports configured to receive a plurality of cables at a first point,
at least a portion of a perimeter of the plurality of top ports is sloped,
the bottom plate defines a plurality of bottom ports configured to receive the plurality of cables at a second point,
the strain relief assembly is movable between an open position and a closed position,
in the open position, the plurality of top ports and the plurality of bottom ports collectively define a first passage area, and
in the closed position, the plurality of top ports and the plurality of bottom ports collectively define a second passage area smaller than the first passage area.
2. The strain relief assembly of claim 1 , wherein
the bottom plate comprises a plurality of retaining devices which engage an first top surface of the top plate from second top surface of the top plate engaged with the bottom plate, and
the plurality of retaining devices are configured to retain the top plate to the bottom plate in the open position.
3. The strain relief assembly of claim 2 , wherein the retaining device is extruded material.
4. The strain relief assembly according to claim 1 , wherein the plurality of top ports are coaxial to the plurality of bottom ports in the open position.
5. The strain relief assembly according to claim 1 , wherein the portion of the perimeter of plurality of top ports that is sloped slopes to a sharp edge configured to engage a respective cable of the plurality of cables.
6. The strain relief assembly according to claim 1 , wherein each of the plurality of bottom ports includes a sharp edge configured to engage a respective cable of the plurality of cables.
7. The strain relief assembly according to claim 1 , further comprising a fastener configured to move the strain relief assembly from the open position to the closed position in response to the fastener being fastened.
8. The strain relief assembly of claim 7 , wherein:
a center line of the fastener defines a longitudinal axis; and
the strain relief assembly moves from the open position to the closed position in response to the top plate translating along the longitudinal axis.
9. The strain relief assembly according to claim 1 , wherein each of the plurality of top ports are configured to apply a shear force on the plurality of cables at the first point in the closed position.
10. The strain relief assembly according to claim 1 , wherein each of the plurality of bottom ports are configured to apply a shear force on the plurality of cables at the second point in the closed position.
11. A strain relief assembly for a plurality of cables comprising:
a bottom plate comprising an overlap edge and defining a plurality of bottom ports; and
a top plate defining a plurality of top ports, wherein at least a portion of a perimeter of the plurality of top ports is sloped, the top plate being movable between an open position and a closed position, in the open position the top plate is retained to the bottom plate via the overlap edge, and in the closed position the top plate is immovably coupled to the bottom plate.
12. The strain relief assembly according to claim 11 , wherein the overlap edge extruded material.
13. The strain relief assembly according to claim 11 , wherein the plurality of top ports are coaxial to the plurality of bottom ports in the open position.
14. The strain relief assembly according to claim 11 , wherein each of the plurality of top ports include a sharp edge configured to engage a respective cable of the plurality of cables.
15. The strain relief assembly according to claim 11 , wherein each of the plurality of bottom ports include a sharp edge configured to engage a respective cable of the plurality of cables.
16. The strain relief assembly according to claim 11 , wherein each of the plurality of top ports are configured to apply a shear force on the plurality of cables in the closed position.
17. The strain relief assembly as in one of claims 11-16 , in which each of the plurality of bottom ports are configured to apply a shear force on a respective cable the plurality of cables in the closed position.
18. The strain relief assembly of claim 1 , further comprising a collar coupled to the bottom plate, wherein the collar is couplable to a cable enclosure.
