Description

OPTIC CABLE STRIPPING AUXILIARY TOOL CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Chinese Patent Application No.201210059868.X filed on March 8, 2012 in the State Intellectual Property Office of China, the whole disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to an optical fiber connection field, more particularly, relates to an optic cable stripping auxiliary tool used during coupling fibers in the field.

Description of the Related Art

The fiber optic connector is a necessary device in a fiber communication system. With the development of a local fiber communication network, more particularly, for meeting requirements of fiber to the network (FTTN) and fiber to the home (FTTH), the demand on the fiber optic connector is rapidly increasing. The conventional manufacture technology of the fiber optic connector, for example, assembling and grinding in a factory, cannot satisfy with such demand any longer, and has a disadvantage of high cost. Accordingly, there is a great demand on a fiber optic connector that is adapted to be quickly and simply assembled in the field.

The field-assembled fiber optic connector must possess many advantages of, such as saving time, saving labor, and facilitating operation. Most of all, a reliable fiber optic connector should be quickly and simply assembled in a few minutes. Tools used together with the field-assembled fiber optic connector generally comprise optic cable stripping pincers, a length measuring tool, an optic cable stripping auxiliary tool, a fiber cutting tool, and so on. The field-assembled fiber optic connector mainly comprises a fiber splicing unit for splicing fibers and a fiber fixing unit fixedly connected to the fiber splicing unit.

Generally, splicing fibers comprises the following steps of: peeling a section of protection layer off an optic cable to expose a section of bared fiber; fixing the peeled optic cable in the optic cable stripping auxiliary tool and scraping a coated layer off the bared fiber to be spliced; cutting the bared fiber to have a predetermined length by a cutter; inserting the bared fiber having the predetermined length into the fiber splicing unit by a fiber fixing unit to abut against another fiber pre-embedded in the fiber splicing unit; and fixing a fiber boot on the fiber fixing unit to fix the optic cable on the fiber optic connector.

In the prior arts, two conventional methods for pre-processing an optic cable before connecting the optic cable to the fiber optic connector are often used. One of the

conventional methods comprises a step of manually scraping the coated layer off the bared fiber and cutting the bared fiber. However, this method has many disadvantages, such as an unstable assembling effect, an unreliable quality and a low efficiency, and an inaccurate length of the fiber cut by the cutter. The other conventional method comprises a step of fixing the protection layer of the optic cable with a conventional optic cable stripping auxiliary tool. However, the bared fiber exposed out of the protection layer cannot be fixed by the conventional optic cable stripping auxiliary tool and may be swayed during assembling the optic fiber connector, degrading the quality of scraping the coated layer off the bared fiber. Furthermore, the conventional optic cable stripping auxiliary tool is often specially manufactured by a company and only adapted to a special fiber cutter of the company, therefore, the conventional optic cable stripping auxiliary tool is limited in use and cannot be adapted for various different types of fiber cutters.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE IVENTION

Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiment set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.

As shown in Figs.1-9, an optic cable stripping auxiliary tool 10 mainly comprises a cable fixture module 20 for fixing an optic cable having a protection layer and a bared fiber fixture module 30 connected to a front end of the cable fixture module 20 to fix a bared fiber of the optic cable.

For the purpose of understanding the present invention well, in all embodiments set forth herein, one end of the optic cable stripping auxiliary tool 10 in a direction of inserting the optic cable and the bared fiber thereof into the optic cable stripping auxiliary tool 10 is defined as a front end (a right side end shown in drawings), and the other end of the optic cable stripping auxiliary tool 10 in an opposite direction to the insertion direction is defined as a rear end (a left side end shown in drawings).

As shown in Figs.2-3, the cable fixture module 20 comprises two side walls 21 and two sets of sloping arms 22. In an inner space formed between the two side walls 21, the two sets of sloping arms 22 extend forward and inward from the two side walls 21, respectively. A cable passage 23 for receiving and fixing the optic cable (not shown) having the protection layer is formed between the opposite sets of sloping arms 22.

In an exemplary embodiment of the present invention, the sloping arms 22 may be elastic and deformable, therefore, the cable passage 23 between the sloping arms 22 may be adapted to receive and fix various cables with different diameters therein, for example, a round cable or a 8-like cable.

The cable fixture module 20 may further comprise a cover 24. One side of the cover 24 is hinged to one of the side walls 21 , and the other side of the cover 24 is fastened to the other of the side walls 21 in a snap-fit manner to close and open the cover 24. Specifically, two through holes 241 with a distance therebetween are formed in the one side of the cover. A portion between the through hole 241 and the side wall 21 is formed as a shaft 242, and an arc protrusion 211 is formed on the respective side wall 21 of the cable fixture module 20. The arc protrusion 211 has an inner space for receiving the shaft 242 so that the cover 24 may be turned on the cable fixture module 20 by the rotation of the shaft 242 in the arc protrusion 21 1. A hook 243 extending downward is formed on the other side of the cover 24. When the cover 24 is closed on the cable fixture module 20, the hook 243 is fastened to the bottom of the other side wall 21 in a snap-fit manner to fix the cover 24 on the cable fixture module 20. But the present invention is not limited to this, the cover 24 may be fixed on the cable fixture module by other means to effectively fix the optic cable in the cable fixture module.

In an optic cable stripping auxiliary tool according to a first exemplary embodiment of the present invention, the bared fiber fixture module 30 may comprise a fiber passage 33 to allow the bared fiber to pass therethrough and a fixing clamp 34 engaged with the fiber passage 33. The fiber passage 33 comprises two sidewalls configured to be closed with each other by a clamping action of the fixing clamp 34 to clamp the bared fiber. Furthermore, the bared fiber fixture module 30 may further comprise a frame 31 in which two elastic sidewalls 32 are provided. The two elastic sidewalls 32 extend in a longitudinal direction (the insertion direction) from a rear portion to a front portion of the frame 31 , and the fiber passage 33 is formed between the two sidewalls 32 to allow the bared fiber to pass threrethrough. The fiber passage 33 is communicated with the cable passage 23 of the cable fixture module 30 so that the bared fiber of the cable may extend from the cable passage to the fiber passage 33.

In an exemplary embodiment of the present invention, as shown in Fig. 9, the fixing clamp 34 is slidably engaged to the sidewalls 32 of the fiber passage 33. A slide rail is provided on one of the fixing clamp 34 and the fiber passage 33, and a slide groove mated with the slide rail is provided on the other of the fixing clamp 34 and the fiber passage 33. In this way, the fixing clamp 34 may be slid relative to the fiber passage 33. Furthermore, the fixing clamp 34 comprises two wings abutting against outer sides of the two sidewalls 32 of the fiber passage 33. At least a part of the two sidewalls 32 of the fiber passage 33 has a thickness gradually increased from the rear to the front of the fiber passage 33. Accordingly, during the fixing clamp 34 is slid from the rear with thinner sidewalls to the front with thicker sidewalls of the fiber passage 33, the width of the fiber passage 33 is gradually narrowed to clamp and fix the bared fiber well.

Furthermore, as shown in Fig.9, the fixing clamp 34 is a recess body and has a substantially U-shaped cross section. The recess body has a depth substantially

corresponding to the height of the sidewall 32 to receive the sidewall 32. Two top sides of the opening of the recess body extend inward to form the slide groove to limit the sidewall 32 in the recess body. The sidewalls of the recess body are elastic and produce an inward elastic force when the recess body is driven toward the front with thicker sidewalls 32 of the fiber passage 33 to reliably clamp the bared fiber arranged in the fiber passage 33. Each of the two sidewalls 32 of the fiber passage 33 has an outwardly extending protrusion 321 formed on a front end thereof to prevent the fixing clamp 34 from being further slid forward. A U-shaped groove 35 for receiving the bared fiber is formed at the front end of the fiber passage 33 and communicated with the fiber passage 33 so that a coated layer can be easily scraped off the bared fiber with a pincer before the bared fiber is cut by a cutter (not shown).

As shown in Figs.1-2, the optic cable stripping auxiliary tool 10 may further comprises a handle 40 connected to the rear end of the cable fixture module 20. The handle 40 extends upward and backward from the rear portion of the cable fixture module 20 to form a substantially domed structure, so that an operator may easily hold it and send the cable fixture module 20 and the bared fiber fixture module 30 to the cutter without any

interference. A tail end of the handle 40 is formed as a sloping portion 41 inclined downward, so that the operator may push the sloping portion 41 to drive the optic cable stripping auxiliary tool 10 into the cutter. A longitudinal handle passage 42 is formed in the middle of the handle 40 and communicated with the cable passage 23. Thereby, the unpeeled cable can extend backward from the cable fixture module 20 and further extend out of the longitudinal handle passage 42 in the middle of the handle 40.

In an exemplary embodiment of the present invention, the handle 40, the cable fixture module 20 and the bared fiber fixture module 30 have a substantially equal width.

As shown in Figs.8-9, the optic cable stripping auxiliary tool 10 may further comprises a foldable bracket 50 mounted on and hinged to the bottom of the bared fiber fixture module 30. The foldable bracket 50 extends from the front portion of the bottom of the bared fiber fixture module 30, and the front portion of the foldable bracket 50 has a shape adapted for that of a corresponding cutter so that the optic cable stripping auxiliary tool 10 can be placed in the cutter to cut the bared fiber. The bracket 50 has two protrusion shafts 51 located at both sides of the rear portion of the bracket and extend outward, and recesses or holes 312 for receiving the protrusion shafts 51 are formed in corresponding positions of support walls 311 of the frame 31 of the bared fiber fixture module 30. In this way, the bracket 50 may be folded by rotating the protrusion shafts 51 mounted in the holes 312. A notch 313 is formed in the bottom of each of the support walls 311 of the bared fiber fixture module 30, and arms 52 extending from two sides of the front portion of the bracket 50 may be received in the notches 313 so that the bracket 50 may be turned from a deployed state in which the bracket 50 extends beyond the front portion of the bared fiber fixture module 30 to a folded state in which the bracket 50 is located in the bottom of the bared fiber fixture module 30. An elastic protrusion 314 may be formed in the notch 313, and the arms 52 at both sides of the front portion of the bracket 50 may be fixed in the notches 313 by the elastic protrusions 314, so that the bracket 50 may be locked in the folded state.

Hereafter, it will describe a method of using the optic cable stripping auxiliary tool 10, the method mainly comprising the steps of:

Firstly, peeling a section of protection layer off an optic cable with pincers to expose a section of bared fiber;

Secondly, putting the optic cable having the protection layer in the cable passage 23 of the cable fixture module 20, putting the bared fiber in the fiber passage 33 of the bared fiber fixture module 30, and passing the other portion of the cable through the handle passage 42 of the handle 40;

Then, closing the cover 24, and pushing the fixing clamp 34 from the rear portion to the front portion of the bared fiber fixture module 30 to clamp the bared fiber;

Afterward, scraping the coated layer off the bared fiber; and placing the optic cable stripping auxiliary tool 10 into the cutter to cut the bared fiber to have a predetermined length.

In this way, the preparation work to splice the fiber is finished. Furthermore, the foldable bracket 50 may be positioned in the folded state or in the deployed state according to types of the cutters. Figs.10-14 show an illustrative perspective view of an optic cable stripping auxiliary tool according to a second exemplary embodiment of the present invention. The optic cable stripping auxiliary tool of the second embodiment is same as the optic cable stripping auxiliary tool of the first embodiment except for the fixing clamp. Thereby, in the following description, the like reference numerals refer to the like elements.

As shown in Figs.10-14, in the optic cable stripping auxiliary tool of the second embodiment, the bared fiber fixture module comprises a fixing clamp 36 engaged with the fiber passage 33 defined by the two sidewalls 32. The fixing clamp 36 comprises two pivotal mechanisms provided at outer sides of the two sidewalls 32, respectively. Each of the pivotal mechanisms comprising: two pivot shafts 363 mounted at the outer sides of the two sidewalls in a first direction (a longitudinal direction) substantially parallel to the fiber passage 33; and two pressing blocks 362 mounted on the pivot shafts 363 and rotatable together with the pivot shafts 363. The two pressing blocks 362 are capable of driving the sidewalls 32 to be closed toward each other to clamp the bared fiber when the two pressing blocks 362 is rotated to be substantially perpendicular to the sidewalls 32 of the fiber passage 33. The pivot shafts 363 are pivotally engaged in recesses 316 (shown in Fig.12) formed in the front and rear support walls of the bared fiber fixture module 30. The pivotal mechanism further comprises an operation portion 361 mounted on the pivot shaft 363 and substantially opposite to the pressing block 362. That is, the operation portion 361 and the pressing block 362 both are located in a substantially same plane. The pivotal mechanism can be driven to rotate about the pivot shaft 363 by the operation portion 361 so that the pressing block 362 can be driven to rotate between a loosened state and a pressed state.

In an exemplary embodiment of the present invention, the operation portion 361, the pressing block 362 and the pivot shaft 363 of the pivotal mechanism can be molded into one single piece.

As shown in Figs.10-12, when the pressing block 362 is in the loosened state, the pressing block 362 is separated from the sidewall 32, for example, a plane where the pressing block 362 is located is substantially parallel to the sidewall 32 so that the sidewall 32 is kept in a natural state where the sidewall 32 does not exhibit any deformation. As shown in Figs.13-14, when the pressing block 362 is in the pressed state, the pressing block 362 is abutted against the sidewalls 32 so that the sidewalls 32 are pressed by the pressing block 362 to displace inward, thereby, the fiber passage 33 is narrowed to tightly clamp the bared fiber arranged in the fiber passage 33. In this way, even if the sidewalls 32 are made of a material that does not have elasticity or has less elasticity, the sidewalls 32 still can be pressed by the pressing block 362 to be closed with each other to clamp the bared fiber arranged in the fiber passage 33.

Furthermore, the bared fiber fixture module further comprises two support walls 311 disposed at the outsides of the sidewalls 32 of the fiber passage 33 respectively and extending in the first direction (the longitudinal direction). A notch 315 for fitting with the operation portion 361 is formed in the support wall 311. In this way, as shown in Fig.13, when the pressing block 362 is in the pressed state, the operation portion 361 may be received in the notch 315.

Although it has described the optic cable stripping auxiliary tool comprising two pivotal mechanisms according to the second embodiment, the present invention is not limited to this, the optic cable stripping auxiliary tool may comprise only one pivotal mechanism provided at the outside of one of the sidewalls 32. Furthermore, an angle between a second direction in which the pressing block 362 extends and a third direction in which the operation portion 361 extends may be in a range of 90-180 degrees so long as the pressing block 362 may be rotated to the pressed state or the loosened state by the operation portion 361.

Although several exemplary embodiments have been shown and described, it would be appreciated by those skilled in the art that various changes or modifications may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
