Optical fiber cable connector with integrated cable splitting
View Patent ↗An optical cable connector is disclosed herein. The optical cable connector includes a housing; an aperture on a side of the housing for receiving unsplit duplex optical cable; a sharp edge, disposed within the housing and positioned to split a portion of the optical cable into two optical fibers when the cable is inserted into the aperture, the fibers for carrying optical signals; and electro-optical transceivers, disposed within the housing and aligned with the two optical fibers to receive the optical signals, the transceivers configured to convert the optical signals into electrical signals. Integrating the sharp edge within the connector precludes a user from having to manually split optical cable prior to inserting the cable into the connector, thereby making the connector relatively easy to use and reducing the likelihood the user will be injured.
1. An optical cable connector, comprising
(a) a housing;
(b) an aperture extending through the housing for receiving an optical cable having at least two optical fiber cores for carrying optical signals, each optical fiber core being optically separated and physically interconnected by sheathing material;
(c) a sharp edge, positioned within the housing so as to split the sheathing material of the optical cable thereby physically separating at least two of the optical fiber cores when the cable is inserted through the aperture and into the housing; and
(d) electro-optical transceivers configured to convert the optical signals into electrical signals, each transceiver positioned inside the housing so as to be in optical communication with a physically separated optical fiber core inside the housing.
2. An optical cable connector as claimed in claim 1 further comprising a cable guideway inside the housing having a front end in communication with aperture and a rear end in communication with the transceivers, and wherein the sharp edge is positioned in the guideway facing the aperture.
3. An optical cable connector as claimed in claim 2 wherein the cable guideway is a groove on an inside surface of the housing and wherein the sharp edge is a blade which separates a portion of the groove into a pair of passages each in communication with one of the transceivers.
4. An optical cable connector as claimed in claim 3 wherein the cable guideway comprises a pair of grooves on top and bottom inside surfaces of the housing, the pair of grooves aligned to form a bore inside the housing and wherein at least part of the bore is sized to frictionally engage the optical cable.
5. An optical cable connector as claimed in claim 4 wherein the bore is sized to receive the optical cable such that the sheathing material interconnecting the pair of optical fiber cores is positioned against the sharp edge when the optical cable is inserted inside the housing.
6. An optical cable connector as claimed in claim 5 wherein the aperture extends through a front wall of the housing, the transceivers are located near a rear wall of the housing, and the housing has a plurality of slots through which pins of the transceivers extend out of the housing.
7. An optical cable connector as claimed in claim 6 wherein the housing further comprises a plurality of transceiver cavities on at least one inside surface of the housing between the rear wall and the groove, each transceiver cavity for receiving one of the transceivers.
8. An optical cable connector as claimed in claim 7 further comprising a lever assembly, and wherein the housing further comprises a lever assembly cavity on at least one inside surface of the housing and in communication with the aperture and cable guideway, the lever assembly movable within the lever assembly cavity between a secured position wherein lever assembly frictionally engages a portion of the optical cable inserted through the aperture and into the bore, and an unsecured position wherein the lever assembly does not frictionally engage the optical cable inserted through the aperture and into the bore.
9. An optical cable connector as claimed in any one of claims 1 to 7 further comprising a lever assembly disposed within the housing and having a cable retaining member, the lever assembly movable inside the housing between a secured position wherein the member frictionally engages the optical cable inserted through the aperture, and an unsecured position wherein the member does not contact the optical cable inserted through the aperture.
10. An optical cable connector as claimed in claim 9 wherein an inside surface of the housing comprises a lever assembly cavity in which the lever assembly is slidable between the secured and unsecured positions.
11. An optical cable connector as claimed in claim 10 wherein the lever assembly cavity has a surface inclined such that the cable retaining member is elevated when in the secured position relative to when the cable retaining member is in the unsecured position.
12. An optical cable connector as claimed in claim 11 wherein the lever assembly further comprises an actuation member protruding out of the housing and movable by a user to move the lever assembly between the secured and unsecured positions.
13. An optical cable connector as claimed in claim 12 wherein the housing comprises a front wall comprising the aperture and an opening through which the actuation member extends, the opening dimensioned to constrain the actuation member to move within the width of the housing.
14. An optical cable connector as claimed in claim 10 wherein the lever assembly further comprises an actuation member protruding out of the housing and movable by a user to move the lever assembly between the secured and unsecured positions.
15. An optical cable connector as claimed in claim 14 wherein the housing comprises a front wall comprising the aperture and an opening through which the actuation member extends, the opening dimensioned to constrain the actuation member to move within the width of the housing.
16. An optical cable connector as claimed in claim 9 wherein the lever assembly further comprises an actuation member protruding out of the housing and movable by a user to move the lever assembly between the secured and unsecured positions.
17. An optical cable connector as claimed in claim 16 wherein the housing comprises a front wall comprising the aperture and an opening through which the actuation member extends, the opening dimensioned to constrain the actuation member to move within the width of the housing.
18. An optical cable connector as claimed in claim 9 further comprising a positioning wedge protruding from the inner surface of the housing, and wherein the cable retaining member further comprises a post protruding therefrom, the post and wedge positioned to contact each other and at least one of the post and wedge having sufficient flexibility that the post is movable past the wedge when the cable retaining member moves between the secured and unsecured positions.
