An optical fiber fault point auxiliary positioning and online optical fiber auxiliary splicing device

Abstract

This utility model discloses an auxiliary optical fiber fault location and online optical fiber auxiliary pairing device, relating to the field of optical fiber communication technology. By fixing the adjusting block at a point corresponding to the optical fiber model, this utility model ensures that the push rod's length remains consistent with each push. Specifically, each time the adjusting block enters the limiting groove and abuts against the inner wall of the limiting groove, the end of the push rod stops moving in the same position. This facilitates repeated changes in the macrobending degree of the same type of optical fiber, simplifying repetitive operations and eliminating the need for fine adjustments each time, making it more convenient to use. Furthermore, when the adjusting block abuts against the inner wall of the limiting groove, the limiting structure can limit the adjusting block, ensuring that once the optical fiber macrobending reaches a predetermined degree, it automatically maintains that degree of macrobending, facilitating inspection by personnel. Moreover, when the optical fiber model changes, only the position of the adjusting block on the push rod needs to be readjusted, resulting in better performance.

Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication technology, and in particular to an optical fiber fault point auxiliary location and online optical fiber auxiliary fiber pairing device. Background Technology

[0002] The work of locating fiber optic faults and determining fiber optic fault points on optical cable lines is highly challenging. To address the problems of easily severing other normally functioning fibers, requiring re-splicing of severed fibers, complex procedures, and the often km-level discrepancy between drawings and actual field conditions, the fault location remains difficult. Patent document CN210405316U discloses an auxiliary fiber optic fault point location and online auxiliary fiber optic pairing device, including an operating table, a first positioning fixture, a second positioning fixture, a movable fixture, and an operating unit. The first, second, and movable fixtures are all mounted on the operating table, with the movable fixture movably positioned between the first and second positioning fixtures. The fiber optic cable can pass around the first, movable, and second positioning fixtures, and the position of the movable fixture on the operating table can be changed by the operation of the operating unit to alter the radius of curvature of the fiber optic cable connected between the three fixtures. This invention modifies the macrobending degree of the optical fiber reference point online, causing changes in optical path attenuation at the reference point. By comparing the results with an optical time domain reflectometer, the specific fiber core and location of the attenuation can be quickly determined, thus achieving the purpose of locating the fiber and fault points and improving the efficiency and quality of optical cable line maintenance.

[0003] Based on the above search and combined with existing technology, it was found that existing fiber optic fault point auxiliary location and online fiber optic auxiliary fiber pairing devices are inadequate. Therefore, there is a need for a fiber optic fault point auxiliary location and online fiber optic auxiliary fiber pairing device. Utility Model Content

[0004] The purpose of this application is to provide an optical fiber fault point auxiliary location and online optical fiber auxiliary fiber pairing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: an optical fiber fault point auxiliary location and online optical fiber auxiliary pairing device, including a mounting base and a sliding seat slidably mounted on the mounting base, the sliding seat sliding laterally along the central axis of the mounting base, and auxiliary positioning and auxiliary pairing components are jointly mounted on the upper surface of the mounting base and the sliding seat.

[0006] A connecting part is formed at the upper end of the sliding seat, and a push rod is detachably fixed on the connecting part;

[0007] A support block is fixed to one side of the upper end of the mounting base, and a limit groove is provided on the side of the support block away from the positioning circle block.

[0008] The end of the push rod away from the connecting part slides through the support block, and an adjusting block is adjustablely sleeved on the push rod. The adjusting block can slide or be fixed along the axis of the push rod.

[0009] The adjusting block and the limiting groove are fitted with a clearance. The support block is equipped with a limiting structure for limiting the adjusting block. When one side of the adjusting block is pressed against the inner wall of the limiting groove near the sliding seat, the limiting structure limits the adjusting block and stops the adjusting block from moving.

[0010] Preferably, the push rod has limit holes, and multiple limit holes are distributed in an equidistant array along the axial direction of the push rod;

[0011] An installation groove is provided on the inner side of the adjusting block, and a limiting protrusion is slidably connected in the installation groove. The end of the limiting protrusion protruding from the installation groove is hemispherical.

[0012] The limiting protrusion is elastically connected to the inner wall of the mounting groove by a compression spring.

[0013] Preferably, a fastening bolt is threaded through the upper end of the adjusting block, and one end of the fastening bolt extends to the inner side of the adjusting block and abuts against the peripheral wall of the push rod.

[0014] Preferably, the push rod surface is provided with a guide groove, which is connected to multiple limiting holes and extends along the arrangement direction of the limiting holes, and the depth of the guide groove is less than half the depth of the limiting holes.

[0015] Preferably, the limiting structure includes a limiting pin and a tension spring. The lower end of the limiting pin slides through the top wall of the support block and extends into the limiting groove. The bottom wall of the limiting pin is an inclined surface that is inclined toward the side away from the sliding seat.

[0016] The lower end of the tension spring is fixed to the upper surface of the support block, and the upper end of the tension spring is fixed to the upper end of the limit pin.

[0017] Preferably, the auxiliary positioning and auxiliary fiber alignment assembly includes a positioning circle and a positioning post;

[0018] There are three positioning blocks. Two of them are fixed to the upper surface of the mounting base. The two positioning blocks are symmetrical about the central axis of the mounting base. The third positioning block is fixed to the upper end of the sliding seat and is located between the two positioning blocks on the mounting base. There are also two positioning posts fixed on the mounting base, which are symmetrically arranged along the central axis of the mounting base. The two positioning posts are located on the outer side of the two positioning blocks.

[0019] In summary, the technical effects and advantages of this utility model are as follows:

[0020] 1. In this utility model, by fixing the adjusting block at the point corresponding to the fiber optic model, the length of the push rod pushed each time can be kept consistent. That is, each time the adjusting block enters the limiting groove and abuts against the inner side wall of the limiting groove, the end of the push rod is in the same position when it stops moving. This makes it easy to repeatedly change the macrobending degree of the same type of fiber optic cable, which is convenient for repeated operation and does not require fine adjustment for each operation, making it more convenient to use.

[0021] At the same time, when the adjusting block is pressed against the inner wall of the limiting groove, the limiting structure can limit the adjusting block, that is, ensure that after the optical fiber macrobend is bent to a predetermined degree, it can automatically maintain the degree of macrobend so that the staff can carry out the inspection.

[0022] Furthermore, when the fiber optic cable model changes, simply readjust the position of the adjustment block on the push rod. This allows for better compatibility with different fiber optic cable models, resulting in better performance.

[0023] 2. In this utility model, by setting the guide groove, during the adjustment of the position of the adjusting block, when the limiting protrusion is outside the limiting hole, the hemispherical end of the limiting protrusion slides in contact with the guide groove, thereby guiding the movement direction of the limiting protrusion, so that the limiting protrusion can move accurately into the next limiting hole, avoiding the circumferential rotation of the limiting protrusion after leaving the limiting hole, which would make it difficult to align with the next limiting hole, making the adjustment of the adjusting block more accurate, convenient and quick.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example: Reference Figure 1-3 The fiber optic fault point auxiliary location and online fiber optic auxiliary pairing device shown includes a mounting base 1 and a sliding base 2 slidably mounted on the mounting base 1. The sliding base 2 slides laterally along the central axis of the mounting base 1. An auxiliary positioning and auxiliary pairing component is mounted on the upper surface of the mounting base 1 and the sliding base 2. The auxiliary positioning and auxiliary pairing component includes a positioning block 3 and a positioning post 4.

[0031] There are three positioning blocks 3. Two positioning blocks 3 are fixed to the upper end face of the mounting base 1. The two positioning blocks 3 are symmetrically arranged about the central axis of the mounting base 1. The other positioning block 3 is fixed to the upper end of the sliding seat 2 and is located between the two positioning blocks 3 on the mounting base 1. Two positioning posts 4 are also fixed on the mounting base 1 and are symmetrically arranged along the central axis of the mounting base 1. The two positioning posts 4 are located on the outside of the two positioning blocks 3 respectively.

[0032] When it is necessary to assist in locating fiber optic faults or perform assisted fiber pairing on online fibers, simply push the sliding seat 2 so that the sliding seat 2 cooperates with the auxiliary positioning and assisted fiber pairing components on the mounting seat 1, namely the three positioning blocks 3 and the two positioning posts 4. By changing the degree of fiber macrobending, the optical path attenuation of the fiber at the splice box position of the optical cable in operation changes. By comparing the test results with the optical time domain reflectometer, the correspondence between the fiber at the splice box position and the ODF frame port can be realized. The fiber pairing process does not interrupt the fiber core, and the bending attenuation value can be controlled so as not to affect the fiber core service of the optical cable in operation.

[0033] Meanwhile, by changing the degree of macrobending of the optical fiber, the optical path attenuation of the optical fiber reference point changes. Through testing and comparison with an optical time domain reflectometer, the location of the fault point can be determined within a very small error range, accurately judging the location of the fault point and greatly improving the repair speed of optical cable lines, thereby improving the efficiency and quality of optical cable line maintenance.

[0034] A connecting part 21 is formed at the upper end of the sliding seat 2, and a push rod 5 is detachably fixed on the connecting part 21;

[0035] A support block 11 is fixed on one side of the upper end of the mounting base 1, and a limit groove 12 is provided on the side of the support block 11 away from the positioning round block 3.

[0036] The end of the push rod 5 away from the connecting part 21 slides through the support block 11. An adjusting block 6 is adjustablely sleeved on the push rod 5. The adjusting block 6 can slide or be fixed along the axial direction of the push rod 5.

[0037] The adjusting block 6 is fitted with the limiting groove 12 with a clearance. The supporting block 11 is equipped with a limiting structure for limiting the adjusting block 6. When one side of the adjusting block 6 is pressed against the inner wall of the limiting groove 12 near the sliding seat 2, the limiting structure limits the adjusting block 6 and stops the adjusting block 6 from moving.

[0038] Based on the above structure, when changing the macrobending degree of the same type of optical fiber, it is only necessary to fix the adjusting block 6 at the point corresponding to the optical fiber model. This will ensure that the push rod 5 is pushed to the same length each time. That is, when the adjusting block 6 enters the limiting groove 12 and abuts against the inner side wall of the limiting groove 12 each time, the end of the push rod 5 will be in the same position when it stops moving. This makes it easy to repeatedly change the macrobending degree of the same type of optical fiber, which is convenient for repeated operation and does not require fine adjustment for each operation, making it more convenient to use.

[0039] At the same time, when the adjusting block 6 is pressed against the inner wall of the limiting groove 12, the limiting structure can limit the adjusting block 6, that is, ensure that after the optical fiber macrobend is bent to a predetermined degree, it can automatically maintain the degree of macrobend so that the staff can perform inspection.

[0040] Furthermore, when the fiber optic cable model changes, simply readjust the position of the adjusting block 6 on the push rod 5 to better adapt to different fiber optic cable models and achieve better performance.

[0041] Furthermore, the push rod 5 has a limiting hole 51, and multiple limiting holes 51 are provided and are distributed in an equidistant array along the axial direction of the push rod 5. The spacing between the multiple limiting holes 51 is adapted to the difference between various types of optical fibers.

[0042] An installation groove 61 is provided on the inner side of the adjusting block 6. A limiting protrusion 9 is slidably connected in the installation groove 61. The end of the limiting protrusion 9 protruding from the installation groove 61 is hemispherical.

[0043] The limiting protrusion 9 is elastically connected to the inner wall of the mounting groove 61 by a compression spring 91.

[0044] With the setting of the limiting protrusion 9 and the compression spring 91, when the limiting protrusion 9 corresponds to a certain limiting hole 51, the limiting protrusion 9 extends out of the mounting groove 61 and its end extends into the limiting hole 51 under the elastic force of the compression spring 91, thereby limiting the adjustment block 6 and making the adjustment block 6 stop at the point that matches the fiber optic model. This allows the push rod 5 to move a distance that is compatible with the fiber optic model. When it is necessary to change the position of the adjustment block 6, a larger pushing force is applied to the adjustment block 6, which will compress the hemispherical surface of the limiting protrusion 9 and guide the limiting protrusion 9 to retract into the mounting groove 61, facilitating the movement of the adjustment block 6. This changes the position of the adjustment block 6 on the push rod 5, thereby adjusting the distance that the push rod 5 can move, achieving the effect of adapting to different fibers.

[0045] Furthermore, a fastening bolt 62 is threaded through the upper end of the adjusting block 6. One end of the fastening bolt 62 extends to the inner side of the adjusting block 6 and abuts against the side wall of the push rod 5. By setting the fastening bolt 62, after adjusting the position of the adjusting block 6, the fastening bolt 62 is screwed in to make the fastening bolt 62 abut against the push rod 5, which can better limit the position of the adjusting block 6 and prevent the adjusting block 6 from sliding due to external forces. This ensures that the position of the adjusting block 6 is more stable after adjustment. When it is necessary to adjust the position of the adjusting block 6, simply unscrew the fastening bolt 62.

[0046] Furthermore, a guide groove 52 is provided on the surface of the push rod 5. The guide groove 52 is connected to multiple limiting holes 51 and extends along the arrangement direction of the limiting holes 51. The depth of the guide groove 52 is less than half the depth of the limiting holes 51.

[0047] By setting the guide groove 52, during the adjustment of the position of the adjusting block 6, when the limiting protrusion 9 is outside the limiting hole 51, the hemispherical end of the limiting protrusion 9 slides in contact with the guide groove 52, thereby guiding the movement direction of the limiting protrusion 9, so that the limiting protrusion 9 can move accurately into the next limiting hole 51, avoiding the circumferential rotation of the limiting protrusion 9 after leaving the limiting hole 51, which would make it difficult to align with the next limiting hole 51, making the adjustment of the adjusting block 6 more accurate, convenient and quick.

[0048] Furthermore, the limiting structure includes a limiting pin 7 and a tension spring 8. The lower end of the limiting pin 7 slides through the top wall of the support block 11 and extends into the limiting groove 12. The bottom wall of the limiting pin 7 is an inclined surface that is inclined toward the side away from the sliding seat 2.

[0049] The lower end of the tension spring 8 is fixed to the upper surface of the support block 11, and the upper end of the tension spring 8 is fixed to the upper end of the limiting pin 7.

[0050] When the adjusting block 6 moves into the limiting groove 12 with the push rod 5, the front end of the adjusting block 6 first contacts the lower end of the limiting pin 7 and pushes the limiting pin 7 upward along the inclined surface. When one side of the adjusting block 6 abuts against the inner side wall of the limiting groove 12, the adjusting block 6 separates from the lower end of the limiting pin 7. At this time, the limiting pin 7 descends under the elastic force of the tension spring 8 and makes the side wall of one side of the limiting pin 7 abut against the rear side wall of the adjusting block 6, thereby limiting the adjusting block 6 and achieving the effect of keeping the optical fiber at the predetermined macrobending degree, which is convenient for the staff to perform inspection. When it is necessary to move the adjusting block 6, simply pull up the limiting pin 7.

[0051] The working principle of this utility model is as follows: In daily use, by moving the push rod 5, the push rod 5 drives the sliding seat 2 to slide, thereby enabling the three positioning blocks 3 to cooperate with the two positioning posts 4, changing the degree of fiber macrobending, and through further detection, achieving the purpose of fiber optic fault point auxiliary positioning or online fiber optic auxiliary alignment.

[0052] When changing the macrobending degree of the same type of optical fiber, simply fix the adjusting block 6 at the point corresponding to the optical fiber type. This will ensure that the push rod 5 is pushed to the same length each time. That is, each time the adjusting block 6 enters the limiting groove 12 and abuts against the inner side wall of the limiting groove 12, the end of the push rod 5 will be in the same position when it stops moving. This makes it easy to repeatedly change the macrobending degree of the same type of optical fiber, which is convenient for repeated operation and does not require fine adjustment for each operation, making it more convenient to use.

[0053] At the same time, when the adjusting block 6 is pressed against the inner wall of the limiting groove 12, the limiting structure can limit the adjusting block 6, that is, ensure that after the optical fiber macrobend is bent to a predetermined degree, it can automatically maintain the degree of macrobend so that the staff can perform inspection.

[0054] Furthermore, when the fiber optic cable model changes, simply readjust the position of the adjusting block 6 on the push rod 5 to better adapt to different fiber optic cable models and achieve better performance.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
