Method and apparatus for mechanically cleaving a stripped end section of an optic fiber core
View Patent ↗Apparatus for mechanically cleaving a stripped end section of an optic fiber core, including a receiving section including an optic fiber guide for receiving the stripped end section of the optic fiber core; a clamping section for receiving a terminal end section of the optic fiber core from the receiving section and securing said terminal end section in a fixed position; and a cleaving section including a cleaving member and cleaving blade, said member being operable to move between an optic fiber receiving position and an optic fiber cleaving position where the blade is positioned to at least partially fracture the optic fiber core extending between the receiving section and the clamping section, wherein movement of the cleaving member towards the cleaving position effects at least partial separation movement between the guide and the clamping section so as to tension and thereby cleave the optic fiber core extending therebetween.
1. Apparatus for mechanically cleaving a stripped end section of an optic fiber core, comprising:
(a) a receiving section including an optic fiber guide for receiving the stripped end section of the optic fiber core;
(b) a clamping section for receiving a terminal end section of the optic fiber core from the receiving section and securing said terminal end section in a fixed position; and
(c) a cleaving section including a cleaving member and cleaving blade, said member being operable to move between an optic fiber receiving position and an optic fiber cleaving position where the blade is positioned to at least partially fracture the optic fiber core extending between the receiving section and the clamping section,
wherein movement of the cleaving member towards the cleaving position effects at least partial separation movement between the guide and the clamping section so as to tension and thereby cleave the optic fiber core extending therebetween.
2. The apparatus claimed in claim 1 , wherein the cleaving member includes a cleave button and a reset button separated by one or more elongate members which are shaped to translate through corresponding pairs of translation slots of the cleaving section as the cleaving member moves between the receiving position and the cleaving position.
3. The apparatus claimed in claim 2 , wherein the cleaving section includes a sliding member through which the cleaving member translates between the optic fiber receiving position and the optic fiber cleaving position.
4. The apparatus claimed in claim 3 , wherein the sliding member is adapted to move transversely to a direction of movement of the cleaving member as the cleaving member translates through the sliding member towards the cleaving position, the transverse movement effecting said at least partial separation movement between the guide and the clamping section so as to tension and thereby cleave the optic fiber core extending therebetween.
5. The apparatus claimed in claim 4 , wherein the sliding member engages the guide of the receiving section during said transverse movement and forces the guide away from the clamping section thereby effecting said at least partial separation movement between the guide and the clamping section.
6. The apparatus claimed in claim 5 , wherein the cleaving member includes one or more tapered flanges arranged to engage and translate along corresponding tapered sections of the sliding member as the cleaving member moves towards the optic fiber cleaving position to effect the transverse movement.
7. The apparatus claimed in claim 1 , wherein the receiving section includes resilient means for acting against movement of the guide away from the clamping section so as to act to return the guide to its original position when the cleaving member moves from the cleaving position back towards the receiving position.
8. The apparatus claimed in claim 1 , wherein the cleaving member is adapted to travel beyond the cleaving position to a further tensioning position to effect further separation movement between the guide and the clamping section so as to further tension and thereby cleave the optic fiber core extending therebetween.
9. The apparatus claimed in claim 1 , wherein the guide includes a necked barrier for limiting movement of casing of the optic fiber core through the guide.
10. The apparatus claimed in claim 9 , wherein the casing includes cladding, buffer and/or jacket of the optic fiber core.
11. The apparatus claimed in claim 9 , wherein the optic fiber core is tensioned between the necked barrier and the clamping section.
12. The apparatus claimed in claim 1 , wherein the clamping section mechanically clamps the terminal end section of the optic fiber core.
13. The apparatus claimed in claim 12 , wherein clamping section includes a lid and a base, the lid and the base being coupled together by a hinge to mechanically clamp the terminal end section of the optic fiber therebetween.
14. The apparatus claimed in claim 13 , wherein the base includes a storage compartment for temporarily storing cleaved end sections of optic fiber cores.
15. A method for mechanically cleaving an optic fiber core, including the steps of:
(a) providing an apparatus for mechanically cleaving a stripped end section of an optic fiber core, including:
(i) a receiving section including an optic fiber guide for receiving the stripped end section of the optic fiber core;
(ii) a clamping section for receiving a terminal end section of the optic fiber core from the receiving section and securing said terminal end section in a fixed position; and
(iii) a cleaving section including a cleaving member and cleaving blade, said member being operable to move between an optic fiber receiving position and an optic fiber cleaving position where the blade is positioned to at least partially fracture the optic fiber core extending between the receiving section and the clamping section;
(b) inserting the optic fiber core into the guide of the receiving section of the apparatus until a terminal end section of the optic fiber core is arranged in the clamping section of the apparatus;
(c) securing the terminal end section of the optic fiber core in a fixed position in the clamping section; and
(d) moving the cleaving member of the apparatus from a receiving position towards a cleaving position so that a cleaving blade at least partially fractures the optic fiber core,
wherein movement of the cleaving member towards the cleaving position effects at least partial separation movement between the guide and the clamping section so as to tension and thereby cleave the optic fiber core extending therebetween.
16. The method claimed in claim 15 , including the step of further moving the cleaving member from the cleaving position towards a further tensioning position to effect further separation movement between the guide and the clamping section so as to further tension and thereby cleave the optic fiber core extending therebetween.
