Technical Field

Background

With the development of communication technology, optical fiber transmission is increasingly applied to communication systems, and optical fibers are mainly connected with optical fibers through optical fiber connectors and optical fiber adapters. An Optical fiber connector is a plug-in connector based on a single-core plug and an adapter, and is usually a main part of a mechanical connector in an Optical Distribution Network (ODN).

During ODN engineering field implementation and subsequent maintenance, it is often necessary to fabricate fiber pigtails in the field. There are two methods generally used at present: one is field fusion, that is, a fusion splicer is used to fuse a section of optical fiber prefabricated into an end in a factory with an optical cable; the other is field assembly, i.e. assembling a mechanical fiber optic connector directly on the cable. The welding machine and other equipment are needed for on-site welding, and certain requirements are imposed on the operating environment; the field assembly has certain requirements on the quality of operators and certain failure rate. The human factor is often the greatest in the case of field assembly failure. For field assembly, the following problems often arise:

1) the use of miller clamp to remove the coating of the optical fiber 250 is easy to damage the optical fiber;

2) the cutting lengths of the optical fibers are different among different types of cutting knives;

3) the field assembly type quick connector needs to manually align the optical fiber, and the optical fiber is easy to touch the inner wall of the connector during alignment, so that the pollution of a cut end face is caused;

4) it is difficult for an operator in a low light environment or older to perform an optical fiber alignment operation;

5) after the optical fiber is penetrated into the field assembly type quick connector, the bending degree of the optical fiber needs to be manually controlled;

6) after the optical fiber is penetrated, an effective fixing structure is not provided, and the optical fiber butt joint points are easy to separate when subsequent operation is carried out;

7) when an operator operates the optical fiber fixing piece switch, the locking is easy to miss or the locking is not thorough;

8) when the optical cable is cut by high-altitude operation, the optical cable is not fixed and is easy to fall off from a cutting table, so that the operation efficiency is influenced.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Referring to fig. 1 to 4, an embodiment of the present invention provides an optical fiber processing tool including a tool body 1, a rotary position switch 2, and an optical cable buckle push-pull member 3.

The tool body 1 includes a body front 11, and the body front 11 is provided with a first receiving groove 12 having one end extending toward the first end 100 of the tool body 1.

Rotatory gear switch 2 sets up in first accepting groove 12, and rotatory gear switch 2 includes four rotatable and the dog 21 that the interval set up, and every two adjacent dog 21 form the cutting trench 22 of the different degree of depth.

The cable buckle push-pull member 3 is detachably disposed in the first receiving groove 12, and is adapted to receive a cable of an optical fiber to be cut and to alternatively cooperate with any one of the cutting grooves 22 to adjust the length of the optical fiber between the end of the cable and the first end 100 of the tool body 1.

Referring to fig. 5, which is a schematic view of the structure of the optical cable 300, fig. 6 is a schematic view of the optical cable 300 being mounted on the cable buckle push-pull member 3. After the outer sheath is stripped, the coated optical fiber 301 is exposed, and the coated optical fiber 301 is coated to obtain the bare fiber 302, in this embodiment, the optical fiber to be cut is the bare fiber 302, and the bare fiber 302 is assembled into the optical fiber connector after a part of the bare fiber 302 is cut.

The length of the optical fiber between the cable end and the first end 100 of the tool body 1 in this embodiment refers to the length of the coated optical fiber 301 and the bare optical fiber 302 in the tool body 1, because the bare optical fiber 302 needs to be partially extended from the first end 100 of the tool body 1 during cutting, and the length of the optical fiber between the cable end and the first end 100 of the tool body 1, that is, the length of the optical fiber extended from the first end 100, is adjusted. Because the cutting point of the cutting knife 400 of difference is different, but the cutting point of same kind of cutting knife 400 remains unchanged, so stretch out the outer optic fibre length of first end 100 through the adjustment and can control cutting length to can solve the inconsistent problem that leads to cutting length inconsistency of the cutting point of different cutting knives 400, improve general adaptation.

In this embodiment, the adjustment of the length of the optical fiber is realized by matching the rotary shift switch 2 with the optical cable buckle push-pull component 3, specifically, the rotary shift switch 2 includes a rotatable adjusting disk 24, four stoppers 21 are arranged on the adjusting disk 24, and the four stoppers 21 are arranged at intervals to form a cross-shaped channel. The position of the four stops 21 can be adjusted when the adjusting disk 24 is rotated, and every two adjacent stops 21 form cutting slots 22 of different depths. Therefore, each time the adjusting plate 24 is rotated by a certain angle, there are two stoppers 21 to limit the position of the cable buckle pushing and pulling component 3, and the optical fiber of the cable will extend out of the first end 100 through the cross channel. Again, because of the different depths of the cutting slots 22 formed, this results in different lengths of optical fiber extending out of the first end 100. It will be appreciated that to accommodate a greater variety of cutting blades 400, more cutting slots 22 of different depths may be provided in the conditioning disk 24.

In some embodiments, referring to fig. 3 and 4, the cable buckle push-pull member 3 comprises a gripping portion 31 and a guiding portion 32.

The clamping portion 31 is used for clamping the optical cable, and the clamping portion 31 is used for clamping and fixing the optical cable to prevent the optical cable from sliding to influence subsequent processing. Preferably, the gripping portion 31 comprises a gripping groove formed by oppositely arranged tooth-shaped structures 311. The tooth-shaped structure 311 can increase the friction force between the tooth-shaped structure and the optical cable, and can achieve a good anti-skid effect.

The guide portion 32 and the clamping portion 31 are integrally arranged and communicated and used for accommodating optical fibers of optical cables, and a limiting step 321 used for being matched and positioned with the cutting slot 22 is arranged at the joint of the guide portion 32 and the clamping portion 31. Different cutting trench 22 corresponds different cutting length, and all fix a position with the spacing step 321 of optical cable buckle push-and-pull part 3 as the benchmark, consequently can realize cutting length unanimous when using different cutting knife 400.

In addition, the guiding portion 32 is further provided with an optical cable orientation notch 323, and after the optical cable orientation notch 323 is arranged, the optical cable is located, so that subsequent alignment is facilitated.

Furthermore, the bottom end of the guide portion 32 is provided with an anti-disengaging buckle 322, and the rotary position switch 2 is provided with a first anti-disengaging hole 23 matched with the anti-disengaging buckle 322. Specifically, the first escape prevention hole 23 is provided in the adjustment plate 24.

Because the effect of cutting trench 22, the activity of optical cable buckle push-and-pull part 3 in vertical direction is injectd the restraint to can only slide around in cutting trench 22, because the effect of first anticreep hole 23, optical cable buckle push-and-pull part 3 is when sliding to the limited position, anticreep release 322 falls into first anticreep hole 23, consequently can't separate from the optic fibre processing tool voluntarily, thereby realized avoiding influencing operating efficiency because the optical cable buckle drops automatically when high altitude construction, repetitive operation.

In some embodiments, referring to fig. 7, the tool body 1 further includes a body back 13 opposite to the body front 11, the body back 13 is provided with a second receiving groove 14 extending from one end to a second end 200 of the tool body 1, the second end 200 is opposite to the first end 100, the second receiving groove 14 is used for receiving the cable buckle pushing and pulling component 3 and the cable inside the cable buckle pushing and pulling component 3, and the second end 200 is further provided with an open-peel clamp 4 for removing the optical fiber coating.

Wherein, open and peel clamp 4 includes: the clamp comprises an upper clamp 41 and a lower clamp 42 which can be closed and separated, wherein a stripping knife edge 43 is arranged at the closed part of the upper clamp 41 and the lower clamp 42, and stripping clamp limiting parts 44 respectively positioned on the upper clamp 41 and the lower clamp 42 are arranged on two sides of the stripping knife edge 43.

As described above, before the optical cable 300 is assembled into the optical fiber connector, the outer jacket needs to be stripped off to expose the coated optical fiber 301, and then the coating on the end of the coated optical fiber 301 needs to be removed to obtain the bare optical fiber 302, and the bare optical fiber 302 is cut as required and then assembled.

In this embodiment, the optical cable is mounted on the optical cable buckle push-pull component 3, then the optical cable buckle push-pull component 3 is placed in the second receiving groove 14 of the main body back 13, the alignment is completed through the limiting step 321, after the coated optical fiber 301 passes through the upper clamp 41 and the lower clamp 42, the upper clamp 41 and the lower clamp 42 are pinched, the coating on a part of the optical fiber can be stripped by pulling the coated optical fiber 301 through the stripping knife edge 43, and then the bare optical fiber 302 is obtained.

In addition, in the prior art, the coating is mainly removed through the miller clamp, the optical fiber is easily damaged, and the stripping clamp 4 in the embodiment is made of plastic, so that the optical fiber can be prevented from being scratched because the hardness of the plastic is lower than that of the optical fiber.

In summary, in the optical fiber processing tool of the present invention, since the rotary shift switch 2 with adjustable shift is provided, different cutting knives 400 correspond to different cutting slots, and the corresponding cutting slots are selected when the corresponding cutting knives 400 are used, so that the problem of inconsistent cutting lengths can be solved. Meanwhile, the stripping clamp 4 is made of plastic, and the plastic is lower in hardness than the optical fiber, so that the optical fiber can be prevented from being scratched.

Referring to fig. 8, the embodiment of the present invention further provides an optical fiber connector, which includes a connector main body 5, an optical fiber fixing device 6, and a cable buckle push-pull component 3 in the optical fiber processing tool.

Referring to fig. 9, a first receiving cavity 51 and a second receiving cavity 52 are formed in the connector body 5 side by side; the optical fiber fixing device 6 is disposed in the first receiving cavity 51, and the optical fiber fixing device 6 includes an optical fiber ferrule 61 for butt joint and an elastic sheet 62 for clamping and releasing the butt joint.

The optical cable buckle push-pull component 3 is slidably arranged in the second accommodating cavity 52, the optical cable processed by the optical fiber processing tool is fixed in the optical cable buckle push-pull component 3, and when the optical cable buckle push-pull component 3 slides in the second accommodating cavity 52 in place, the optical fiber of the optical cable can be butted with the pre-buried optical fiber in the optical fiber inserting core 61, so that the optical fiber of the optical cable is bent. It can be understood that the optical fiber of the optical cable is designed with slight redundancy when being cut, so that when the optical fiber of the optical cable is butted with the pre-buried optical fiber in the optical fiber ferrule 61, the optical fiber of the optical cable is bent, that is, the optical fiber of the optical cable and the pre-buried optical fiber of the optical fiber ferrule generate butting force when being butted, and thus, the optical fiber of the optical cable and the pre-buried optical fiber can be ensured to be in good and reliable contact.

The connector main body 5 is configured to have an lc (dominant connector) type interface, and the optical fiber fixing device 6 is provided at the head end of the connector main body 5, and the optical fiber fixing device 6 includes four parts, i.e., an optical fiber ferrule 61, an elastic piece 62, an optical fiber fixing device main body 63, and an optical fiber fixing device pressing piece 64.

Further, the cable buckle push-pull member 3 includes a grip portion 31 and a guide portion 32. The clamping portion 31 is used for clamping the optical cable; the guide portion 32 is integrally provided with and communicates with the holding portion 31, and is used for accommodating an optical fiber of an optical cable, and a limiting step 321 for matching and positioning with the connector main body 5 is provided at a joint of the guide portion 32 and the holding portion 31.

Further, referring to fig. 10, the bottom end of the guide portion 32 is provided with an anti-release hook 322, and the connector body 5 is provided with a second anti-release hole 53 engaged with the anti-release hook 322. There is anti-disengaging 322 in optical cable buckle push-and-pull part 3 bottom, and there is spacing step 321 in optical cable buckle push-and-pull part 3 lateral wall, when optical cable buckle push-and-pull part 3 pushed inwards along connector main part 5 axial, anti-disengaging 322 can fall into in the second anticreep hole 53 on connector main part 5 in order to prevent to drop, and spacing step 321 can prevent that optical cable buckle push-and-pull part 3 from continuing to advance simultaneously.

Further, as shown in fig. 11, a guide groove 521 and a limiting groove 522 are disposed in the second receiving cavity 52, and a guide bar 324 is further disposed at the bottom end of the guide portion 32, and the guide bar 324 can slide along the guide groove 521 and can be matched with the limiting groove 522 for limiting. The optical fiber is guided into the connector main body 5 by the optical cable buckle push-pull component 3 through the guide strip 324 sliding along the guide groove 521. After the sliding is in place, the tail end of the limiting groove 522 in the second accommodating cavity 52 can limit the corresponding structure of the guide bar 324, so as to prevent the guide bar from moving up and down, left and right.

Further, the optical fiber connector further includes a cable protection cover 54 capable of being turned around the connector body 5 in the axial direction, a rotation shaft 55 is further disposed on an outer wall of the second receiving cavity 52, and the cable protection cover 54 is riveted to the outer wall of the second receiving cavity 52 through the rotation shaft 55. When the cable buckle push-pull member 3 slides in place in the second receiving cavity 52, the cable protection cover 54 covers the area of the second receiving cavity 52 for protection.

Further, referring to fig. 12, the optical fiber movable connector further includes an optical fiber fixing device switch 7 detachably provided on the connector main body 5, the optical fiber fixing device switch 7 including: a switch handle 71 in a U-shape, a switch jaw 72 and a switch latch 73.

The switch claw 72 is fixed to the U-shaped bottom of the switch handle 71 for being engaged with the connector main body 5. A switch latch 73 is fixed to the U-shaped bottom of the switch handle 71 between the switch jaws 72 for extending into the fiber fixing device 6 to open the fiber fixing device 6.

In addition, because the connector main body 5 is made of a plastic material with higher strength performance, the material wall thickness of parts is reduced, the modes of an optical cable buckle and push rod parts are simplified, the size of the connector is compact, and the size of the connector is reduced by half compared with that of an SC type optical fiber movable connector.

Therefore, in some embodiments, referring to fig. 13, the optical fiber connector includes an LC duplex adapter 8 and a connector holder 9, two connector units are connected to the LC duplex adapter 8, and the connector holder 9 is held in the ends of the connector main bodies 5 of the two connector units. It will be appreciated that with the LC duplex adapter 8, the number of fiber optic connecting cores can be doubled within the same space to achieve high density connection goals.

The above-described fiber handling tool process and fiber optic connector assembly principles are described as follows:

on one hand, firstly, removing the outer sheath of the optical cable 300 by using an optical cable stripper to obtain the coated optical fiber 301;

then, referring to fig. 14, the optical cable 300 is clipped into the cable buckle push-pull member 3, the cable buckle push-pull member 3 is placed on the side of the back surface 13 of the main body of the optical fiber processing tool where the stripping clamp 4 is provided, and the coating on the coated optical fiber 301 is removed by using the stripping clamp 4, so that a bare optical fiber 302 is obtained.

The bare optical fiber 302 is cleaned by using absolute ethyl alcohol, and then as shown in fig. 15, the optical cable buckle push-pull component 3 is placed on the side, provided with the rotary gear switch 2, of the front face 11 of the main body of the optical fiber processing tool, and a corresponding adjusting gear is selected according to the specific model of the cutter 400. Referring next to FIG. 16, the bare fiber 302 is cleaved by placing the fiber handling tool on a cleaver 400. And after the cutting is finished, taking down the optical cable buckle push-pull component 3.

On the other hand, the optical fiber ferrule 61 is firstly installed on the optical fiber fixing device main body 63, and the elastic sheet 62 is used for clamping and fixing the optical fiber fixing device pressing block 64; then the assembled optical fiber fixing device 6 is installed on the connector main body 5, and the optical cable protective cover 54 is covered; finally, the fiber fixture switch 7 is mounted on the connector body 5 such that the fiber fixture is in an open state (i.e., the fiber fixture press block 64 and the fiber fixture body 63 are separated by the switch latch).

After both of them are prepared, as shown in fig. 17, the optical cable buckle push-pull member 3 and the processed optical cable 300 are put together into the second receiving cavity 52, and the axial center line of the bare fiber 302 and the axial center line of the optical fiber ferrule 61 are aligned on the same horizontal line. The optical cable buckle push-pull component 3 is pushed, in the process of pushing the optical cable buckle push-pull component 3, the bare optical fiber 302 enters the optical fiber fixing device 6 and then continues to be pushed, as shown in fig. 18, the coated optical fiber 301 in the optical cable buckle push-pull component 3 automatically forms a bend, and a bent section is obtained.

Referring to fig. 19, the optical fiber fixing device switch 7 is pulled to close the cable protective cover 54, and referring to fig. 20, the optical fiber fixing device switch 7 is removed and the assembly is completed.
