Insert for an optical fiber assembly and optical fiber assembly using an insert
View Patent ↗The present invention relates to an insert for an optical fiber assembly through which an optical fiber element can be pulled out without damage. The insert is provided for guiding a part of the optical cable ( 2 ) which comprises at least one optical fiber element ( 3 ) and being accommodated in a housing of the optical fiber assembly, wherein said part of the optical cable ( 2 ) has a cut-out portion in which a jacket of said optical cable ( 2 ) is partially removed, thereby exposing said at least one optical fiber element ( 3 ). The insert ( 1 ) comprises an optical cable guidance means ( 4 ) for guiding said optical cable ( 2 ) across the insert ( 1 ); a recess ( 5 ) surrounding the exposed optical fiber element ( 3 ) and a bend element ( 6 ) arranged at an end portion of the recess ( 5 ) and projecting from the recess ( 5 ) in a curved manner.
1. An insert for guiding a part of an optical cable comprising at least one optical fiber element and accommodated in a housing of an optical fiber assembly, said part of the optical cable has a cut-out portion exposing said at least one optical fiber element, wherein said insert comprises:
an optical cable guidance means for guiding said optical cable across the insert;
a recess surrounding the exposed optical fiber element, and adapted to receive the cut-out portion; and
a convex bend element arranged at an end portion of the recess and projecting from the recess in a curved manner in a longitudinal direction of the optical cable and towards the recess and thereafter reversely bending to project away from the recess.
2. The insert according to claim 1 , wherein said bent element protrudes the recess in a running direction of the optical fiber element.
3. The insert according to claim 1 , wherein the insert further comprises a crosslink bridging the cut-out portion of the optical cable, wherein said bend element is fixed to said crosslink.
4. The insert according to claim 1 , wherein said bend element has a groove for guiding the optical fiber element in a pull back action.
5. The insert according to claim 4 , wherein said crosslink has an abutment section on its lower side designed to abut against the cut-out portion of the optical cable, wherein said abutment section is divided by the groove into two abutment faces.
6. The insert according to claim 1 , wherein said insert further comprises loop receiving arrangement for holding a loop formed by the pulled-out optical fiber element, wherein said bend element and said crosslink form part of said loop receiving arrangement.
7. The insert according to claim 1 , wherein said guidance means is adapted to receive said jacket of the optical cable in a form fit manner.
8. The insert according to claim 7 , wherein said crosslink is arranged adjacent to said guidance means.
9. The insert according to claim 1 , wherein said insert further comprises a hold-down device for holding remaining optical fiber elements in the cut-out portion, wherein said hold-down device has a slot for separating an optical fiber element from the cut-out portion.
10. An optical fiber assembly for an optical cable comprising:
a housing with a housing lower body and a housing upper body enclosing an insert according to any of the preceding claims, and
a sealing means for sealing the housing.
