Abstract

An optical fiber cleaver having a main body having a channel, a feed block attached to the main body in the channel, the feed block being operable between a front position and a rear position, a length selector for setting an optical fiber cleaving length, the length selector comprising a scale provided on the main body, a display provided on the feed block, and a position indicator operably associated with the scale, a pair of upper and lower clamps which fasten an optical fiber of an optical fiber when the feed block is located in the front position, a slider, a blade carried by the slider, the blade being configured to form an initial partial cleaving, and a push-up member carried by the slider and configured to bend the optical fiber subsequent the initial partial cleaving of the optical fiber is disclosed.

Claims (19)

1. An optical fiber cleaver, comprising:

a main body having a channel extending in a forward-rearward direction;

a feed block attached to the main body in the channel, the feed block being operable between a front position and a rear position;

a length selector for setting an optical fiber cleaving length, the length selector comprising a scale provided on the main body, a display provided on the feed block, and a position indicator operably associated with the scale when the feed block is in the rear position;

a pair of upper and lower clamps which fasten an optical fiber of a fiber-optic cable when the feed block is located in the front position;

a slider movable in a direction generally perpendicular to an axial direction of an optical fiber fastened between the pair of upper and lower clamps;

a blade carried by the slider, the blade being configured to form an initial partial cleaving in the optical fiber fastened between the pair of upper and lower clamps; and

a push-up member carried by the slider and configured to bend the optical fiber subsequent the initial partial cleaving of the optical fiber.

2. The optical fiber cleaver according to claim 1 , wherein the display comprises a step configured for at least partial insertion into a concavity below a lower clamp.

3. The optical fiber cleaver according to claim 1 , wherein a projection is provided on the feed block and a front recess of the channel receives the projection when the feed block is in the front position.

4. The optical fiber cleaver according to claim 3 , wherein a rear recess of the channel receives the projection when the feed block is in the rear position.

5. The optical fiber cleaver according to claim 1 , wherein the feed block slides within the channel.

6. The optical fiber cleaver according to claim 1 , wherein the pair of upper and lower clamps are at least partially held in a position through the use of a magnet.

7. The optical fiber cleaver according to claim 1 , wherein the position indicator is provided on a step that protrudes from a lower portion of the front of the feed block.

8. The optical fiber cleaver according to claim 1 , wherein the position indicator is provided on a shelf that protrudes from an upper portion of the front of the feed block.

9. The optical fiber cleaver according to claim 1 , wherein the position indicator is a groove formed in an upper surface of the feed block.

10. The optical fiber cleaver according to claim 1 , wherein the pair of upper and lower clamps are at least partially constructed of rubber.

11. The optical fiber cleaver according to claim 1 , wherein a spring causes the push-up member to bend the optical fiber subsequent the initial partial cleaving of the optical fiber.

12. The optical fiber cleaver according to claim 11 , wherein the spring is prevented from causing the push-up member to bend the optical fiber subsequent the initial cleaving of the optical fiber until a pin associated with the push-up member moves upward into a groove.
