Field terminating method and device
View Patent ↗A method of terminating a fiber in a connector using a device comprising: (a) positioning a stripped fiber on the device such that the bare fiber portion extends into a first fiber channel of a cleaver; (b) securing the fiber to a fiber retainer slidably attached to the substrate to move along an x axis at a first position; (c) cleaving the bare fiber portion to form a cleaved end; (d) sliding the fiber retainer away from the cleaver along the x axis; (e) causing to be presented a second fiber channel of a connector held in a connector retainer along the x axis; (f) sliding the fiber retainer to the first position along the x axis, thereby causing the cleaved end to extend into the second fiber channel; and (g) actuating the connector while the fiber retainer is at the first position.
1. A method of terminating a fiber in a connector using a device having a substrate with x and y axes, said fiber being stripped to present a bare fiber portion extending from a buffered portion, said method comprising:
(a) positioning a stripped fiber on said device such that said bare fiber portion extends into a first fiber channel of a cleaver;
(b) securing said fiber to a fiber retainer slidably attached to said substrate to move along said x axis at a first position on said x axis;
(c) cleaving said bare fiber portion to form a cleaved end;
(d) sliding said fiber retainer away from said cleaver along said x axis;
(e) causing to be presented a second fiber channel of a connector held between first and second dies in a connector retainer along said x axis;
(f) sliding said fiber retainer to said first position along said x axis, thereby causing said cleaved end to extend into said second fiber channel; and
(g) actuating said first and second dies to move toward each other, thereby compressing said connector held between said first and second dies and thereby clamping said cleaved end to said connector.
2. The method of claim 1 , wherein, in step (e), said second fiber channel is presented by at least one of the following actions (i) sliding said cleaver along said y-axis away from said x axis, (ii) sliding said connector retainer along said y-axis such that said second fiber channel is aligned with said x axis, or (iii) a combination of (i) and (ii).
3. The method of claim 2 , wherein, in step (e), said second fiber channel is presented by sliding said cleaver along said y-axis away from said x axis and sliding said connector retainer along said y-axis to align said second fiber channel with said x axis.
4. The method of claim 3 , wherein said cleaver and said connector retainer are mounted on a common platform that slides along said y-axis.
5. The method of claim 1 , further comprising:
(h) crimping a compressible member on said connector around said buffered portion of said fiber.
6. The method of claim 5 , wherein steps (g) and (h) are performed simultaneously with one action of said device.
7. The method of claim 6 , wherein said one action involves actuating a lever.
8. The method of claim 1 , wherein, in step (f), said cleaved end contacts a fiber stub in said connector before said fiber retainer reaches said first position, thereby causing said fiber to bend when said fiber retainer reaches said first position.
9. The method of claim 1 , wherein said substrate comprises an x track along said x axis and a y track along said y axis.
10. The method of claim 1 , wherein said first position is an extreme point of travel for said fiber retainer along the x track.
11. The method of claim 1 , wherein, in step (c), wherein a cleaved portion of said bare fiber portion is captured in a receptacle.
12. A device for field termination of optical connectors, said device comprising:
a substrate defining x and y axes;
a fiber retainer slidably attached to said substrate to slide along said x axis;
a cleaver having a first fiber channel and being slidably attached to said substrate to slide along said y axis; and
a connector retainer for holding a connector having a second fiber channel and presenting said second fiber channel along said x axis, wherein said connector retainer being slidably attached to said substrate to slide along said y axis.
13. The device of claim 12 , wherein said substrate comprises a groove between said fiber retainer and said cleaver, said groove comprising a stop to abut the end of said buffered portion of said fiber.
14. The device of claim 13 , wherein said groove, a first fiber channel and said second fiber retainer are essentially on a common xy plane.
15. The device of claim 12 , further comprising a receptacle adjacent said cleaver to catch fiber cutoffs after cleaving.
16. The device of claims 12 , further comprising at least one lever, and wherein said connector retainer comprises first and second dies, said first and second dies being configured to hold ends of a connector and being operatively connected to said lever such that actuating said lever causes said first and second dies to move toward each other, thereby compressing a connector held therebetween and thereby actuating the connector to clamp onto said fiber.
17. The device of claims 16 , wherein said connector retainer comprises first and second crimping elements, said first and second crimping elements being biased opened and configured to receive a compressible member of a connector in an open position, said first and second crimping elements being operatively connected to said lever such that actuating said lever causes said first and second crimping elements to move toward each other, thereby crimping said compressible member disposed between them and thereby securing said connector to said fiber.
18. The device of claims 17 , wherein said actuation simultaneously moves said first and second dies and said first and second crimping elements.
19. The device of claims 12 , further comprising a common platform upon which said cleaver and said connector retainer are mounted.
