Strain relief insert
A strain relief device for securing three radially arrayed flat cables coming into a closure includes a body having three armatures extending radially. Each armature includes at least two cantilevered segments extending from the at least one armature in opposing directions. At least one cable may be received in a receiving area partially defined by the armature and the cantilevered segment. Compressive force acting on the strain relief device secures the cables in the receiving area relative to the strain relief device.
1. A strain relief device for securing at least one optical cable to a closure, the strain relief device comprising:
a body, the body having a length and defining a longitudinal axis in general alignment with an axis of the at least one optical cable;
at least one armature, the at least one armature extending from the body;
at least one cantilevered segment, the at least one cantilevered segment extending from the at least one armature;
at least one force concentration lobe, the force concentration lobe located at a distal end of the at least one cantilevered segment;
at least one bending zone, the bending zone located between the at least one armature and the at least one force concentration lobe, the force concentration lobe capable of receiving a radial force and bending the cantilevered segment at the bending zone; and
at least one cable receiving region, the cable receiving region defined by at least the body, the at least one armature and the at least one cantilevered segment.
2. The device of claim 1 , the cable receiving region adapted to receive an optical cable having an ovoid shape.
3. The device of claim 1 , the at least one cable receiving region further defined by at least two armatures and at least two cantilevered segments.
4. The device of claim 3 , the at least two cantilevered segments being opposed to each other and on different armatures, defining a cable receiving gap between them.
5. The device of claim 4 , the at least two cantilevered segments cooperating to secure the at least one optical cable within the cable receiving region.
6. The device of claim 1 , the cable receiving region including at least one cable retention feature for axially retaining the at least one optical cable.
7. The device of claim 1 , the device including at least three armatures, each armature having at least two cantilevered segments extending in opposing directions, the armatures and the cantilevered segments defining at least three cable receiving regions.
8. The device of claim 7 , each armature having at least one stand-off ridge located between each of the at least two cantilevered segments.
9. The device of claim 8 , including at least one depression associated with the bending zone, the at least one depression located substantially between the at least one stand-off ridge and the at least one force concentration lobe.
10. The device of claim 1 , the at least one cable receiving region further defined by at least two armatures and at least two cantilevered segments, the at least two cantilevered segments being opposed to each other and on different armatures, defining a cable receiving gap between them, the at least two cantilevered segments cooperating to secure the at least one optical cable within the cable receiving region, the cable being insertable through the cable receiving gap in a first orientation and rotated about one quarter turn to a second orientation to occupy the cable receiving region.
11. The device of claim 10 , the device adapted to receive a compression device for applying a force to the stand-off ridges and the force concentration lobes, causing the cantilevered segments to flex and secure the at least one optical cable.
