Apparatus for mechanically splicing optic fibers
View Patent ↗An apparatus for mechanically splicing two optic fiber cores, including two holder bodies, moveable relative to each other, each of which includes a retaining device configured to receive, and hold, end sections of said optic fiber cores; and a scoring device coupled with the holder bodies and operable to move along a trajectory relative to the holder bodies, each retaining device being arranged so that said end sections extend therefrom through said trajectory, wherein the scoring device scores the end sections of said optic fiber cores upon movement along the trajectory, and further movement of the scoring device along the trajectory forces the holder bodies away from each other to cleave the end sections of the optic fiber cores; and relative movement of the holder bodies brings cleaved end sections together to affect mechanical splicing of the optic fiber core.
1. An apparatus for mechanically splicing two optic fiber cores, comprising:
(a) two holder bodies, moveable relative to each other, each of which includes a retaining device configured to receive, and hold, end sections of said optic fiber cores; and
(b) a scoring device coupled with the holder bodies and operable to move along a trajectory relative to the holder bodies, each retaining device being arranged so that said end sections extend therefrom through said trajectory,
wherein the scoring device scores the end sections of said optic fiber cores upon movement along the trajectory, and further movement of the scoring device along the trajectory forces the holder bodies away from each other to cleave the end sections of the optic fiber cores; and relative movement of the holder bodies brings cleaved end sections together to affect mechanical splicing of the optic fiber cores.
2. An apparatus according to claim 1 , wherein the scoring device includes a first part of a sliding coupling and the holder bodies include a second part of the sliding coupling, the sliding coupling being arranged to guide the movement of the scoring device.
3. An apparatus according to claim 2 , wherein the sliding coupling is at least partially transversely disposed relative to the trajectory of the scoring device, such that movement of the scoring device along the trajectory causes at least one said holder body to move in a direction transverse to the trajectory, to align the optic fiber cores.
4. An apparatus according to claim 1 , wherein the optic fiber cores are received in the holder bodies in a substantially parallel and non-coaxial manner.
5. An apparatus according to claim 2 , wherein the scoring device includes a substantially wedge-shaped actuator having two faces diverging away from each other, the first part of the sliding coupling being provided on both faces, and wherein movement of the scoring device along the trajectory moves the holder bodies up the faces in the direction of the divergence, thereby forcing the holder bodies away from each other to place the optic fiber cores in tension to affect cleaving thereof.
6. An apparatus according to claim 1 , further including a securing device for securing said scoring device in fixed relation to said apparatus, after cleaving.
7. An apparatus according to claim 6 , wherein said securing device comprises a tang and notched groove for receiving said tang, the apparatus further including a base having one of said tang and notched groove and the scoring device including the other of said tang and notched groove, and wherein the tang is received in the notched groove to hold the scoring device in fixed relation to the base.
8. A method for splicing two exposed optic fiber cores including the steps of:
(a) an apparatus for mechanically splicing two optic fiber cores, comprising:
(i) two holder bodies, moveable relative to each other, each of which includes a retaining device configured to receive, and hold, end sections of said optic fiber cores; and
(ii) a scoring device coupled with the holder bodies and operable to move along a trajectory relative to the holder bodies, each retaining device being arranged so that said end sections extend therefrom through said trajectory;
(b) inserting end sections of optic fiber cores into retaining devices of respective holder bodies, thereby positioning said end sections for scoring by the scoring device;
(c) operating the scoring device to move along the trajectory to score said end sections;
(d) operating said scoring device to move further along said trajectory to urge the holder bodies apart to cleave the end sections; and
(e) moving said holder bodies relative to one another to affect mechanical splicing of said optic fiber cores.
9. A method according to claim 8 , wherein inserting end sections of optic fiber cores involves inserting end sections of optic fiber cores in a parallel and non-coaxial manner.
10. A method according to claim 8 , further including the step of operating said scoring device until a securing mechanism holds said scoring device in fixed relation to a base of said apparatus.
