Description

Technical Field

[0001] The present application relates to the technical field of optical fiber connectors, and in particular to a connector axis alignment device. Background Art

[0002] In an optical communication network, each core of an optical fiber serves as an independent communication channel that can transmit data. An important challenge in the application of optical fiber is the low-loss connection between optical fibers. During the active connection of optical fibers, the two end faces of the optical fibers need to be precisely docked. The most important thing is to align the axes of the two optical fibers so that the light output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. This requires the optical fibers to be aligned so that each core of the pair of optical fibers that need to be docked can be precisely aligned, thereby achieving a low-loss connection between the cores of each optical fiber.

[0003] In the existing optical fiber alignment operation, a common method is to manually observe the optical fiber cross-section and the connector positioning key under a microscope, and rotate the optical fiber to align and fix the rectangular fiber core inside the optical fiber with the connector positioning key. This method is relatively common in practical applications, but it also has problems. For example, manual alignment is highly dependent on the operator's experience and skills, and it is difficult to ensure high-precision alignment, which can easily lead to signal transmission loss and instability. The operation results of different operators may vary greatly, making it difficult to ensure the consistency of product quality. In addition, the operator cannot directly observe the specific situation of the optical fiber end face and cannot judge the effect of the alignment. Utility Model Content

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0024] See also Figure 1-Figure 4 The connector-to-axis device provided in the present application comprises an imaging unit 1, a bracket 2 is provided on one side of the imaging unit 1, a flange 3 is connected to the side of the bracket 2 away from the imaging unit 1, a through hole 4 is provided on the bracket 2, the through hole 4 sequentially passes through the center of the bracket 2 and the flange 3, a connector 5 is inserted in the through hole 4, and an optical fiber 6 is movably inserted in the connector 5;

[0025] The outer sleeve of the connector 5 is provided with a first locking unit 7, one end of the first locking unit 7 can fix the connector 5 in the through hole 4, and the outer periphery of the other end of the first locking unit 7 is rotatably connected with a locking nut 8, and the locking nut 8 cooperates with the first locking unit 7 to fix the optical fiber 6 in the connector 5 with the angle adjusted.

[0026] The imaging unit 1, the bracket 2, the flange 3 and the first locking unit 7 are all coaxially arranged in the horizontal direction.

[0027] In the above embodiments, in the existing connector 5 alignment operation, a common method is to manually observe the end face of the optical fiber 6 and the positioning key of the connector 5 (i.e., the limit block 10 of the present application) under a microscope, rotate the optical fiber 6, so that the rectangular core inside the optical fiber 6 is aligned and fixed with the positioning key of the connector 5. This method may have the problems of low alignment accuracy, low efficiency, difficulty in visualization and poor consistency; low alignment accuracy, that is, manual alignment greatly relies on the experience and skills of the operator, it is difficult to ensure high-precision alignment, and it is easy to cause signal transmission loss and instability; low efficiency, that is, the manual alignment operation process is cumbersome, requires repeated debugging and confirmation, and consumes a lot of time and manpower costs; poor consistency, that is, the operation results of different operators may vary greatly, and it is difficult to ensure the consistency of product quality; difficult visualization, that is, the operator cannot directly observe the specific situation of the end face of the optical fiber 6 inside the connector 5, and can only rely on personal experience to accurately judge the alignment effect.

[0028] The present application sets a coaxial structure of the imaging unit 1, the bracket 2 and the flange 3, fixes the connector 5 on the bracket 2, and can limit the position of the connector 5, so that the connector 5 is in a horizontal state, and the end face of the optical fiber 6 of the connector 5 is presented through the imaging unit 1, so as to realize the visualization of the axis, and the optical fiber 6 is inserted into the connector 5, and the optical fiber 6 is rotated so that the rectangular core inside the optical fiber 6 is in a horizontal state, that is, the optical fiber 6 is coaxial with the connector 5, which can improve the accuracy of the axis and improve the efficiency of the axis. Since the position of the connector 5 is limited, the optical fiber 6 rotates inside the connector 5 after the connector 5 is limited, and the operator does not need to take into account the angle of the connector 5 when rotating the optical fiber 6, that is, the experience and skill requirements of the operator are reduced, which saves labor costs, avoids the problem of differences in operation results of different operators, and ensures the consistency of product quality.

[0029] In addition, a bracket 2 and a flange 3 are provided which are coaxial with the imaging unit 1 in the horizontal direction, and the connector 5 is fixedly connected to the bracket 2 through the first locking unit 7. This enables the axis of the connector 5 to be determined. It is only necessary to rotate the optical fiber 6 so that the rectangular core inside the optical fiber 6 is completely horizontal. This ensures that the rectangular optical fiber 6 and the connector 5 are accurately aligned.

[0030] Among them, the connector 5 of the present application is a D80 connector, and the flange 3 of the present application is a D80 flange that matches the connector 5.

[0031] Further, see Figure 3 A limiting groove 9 is provided on the outer circumference of the flange 3 , and a limiting block 10 matching the limiting groove 9 is provided on the outer circumference of the connector 5 .

[0032] In a possible implementation, during specific use, when the connector 5 is inserted into the through hole 4 passing through the flange 3 and the bracket 2, the limit block 10 on the connector 5 is just stuck in the limit groove 9 on the circumference of the outer wall of the flange 3, which can limit the axial position of the connector 5 in the bracket 2 and the flange 3, and avoid the angle of the connector 5 in the through hole 4 of the bracket 2 and the flange 3 from being deflected.

[0033] Among them, when inserting the optical fiber 6 into the connector 5, the position of the limit block 10 can be observed, and the angular relationship between the end face of the optical fiber 6 and the limit block 10 can be referred to, so that the optical fiber 6 inserted into the connector 5 is in a horizontal state as much as possible, which is convenient for the later adjustment of the angle of the optical fiber 6, that is, it saves the time of adjusting the optical fiber 6 to a horizontal state in the later stage, and improves the axis efficiency.

[0034] Further, see Figure 1 , the flange 3 and the first locking unit 7 are detachably connected.

[0035] In one possible implementation, after the connector 5 passes through the through hole 4 on the bracket 2 and the flange 3, the first locking unit 7 is connected to the flange 3 to fix the connector 5 in the through hole 4 of the bracket 2 and the flange 3. A detachable connection method is provided, which also facilitates the removal of the connector 5 from the bracket 2 and the flange 3 after the shaft alignment is completed, and the replacement of the next connector 5 that needs to be aligned.

[0036] Further, see Figure 1 The first locking unit 7 includes a nut 71 and a locking screw 72 , and the nut 71 is fixedly connected to the locking screw 72 .

[0037] In one possible implementation, the nut 71 is sleeved on the connector 5, and the internal thread 14 of the nut 71 cooperates with the external thread 11 on the flange 3 to fix the connector 5 to the bracket 2 and the flange 3. The locking screw 72 is connected to the end of the nut 71 away from the bracket 2, and the optical fiber 6 can pass through the locking screw 72 and extend to the imaging unit 1.

[0038] Further, see Figure 1 , the locking nut 8 is threadedly connected to the locking screw 72.

[0039] In a possible implementation, the threaded connection between the locking nut 8 and the locking screw 72 can fix the optical fiber 6 that has been inserted into the locking screw 72 and has been adjusted to a certain angle in the locking screw 72 to prevent the position of the optical fiber 6 from rotating.

[0040] Further, see Figure 4 Grooves 12 are evenly formed on the outer circumference of the locking screw 72 , and the diameter of the locking screw 72 gradually shrinks along the direction away from the nut 71 .

[0041] In one possible implementation, the groove 12 passes through the locking screw 72, and three groups of grooves are provided in the groove 12. When the locking nut 8 is sleeved on the locking screw 72, since the diameter of the locking screw 72 gradually decreases, the locking nut 8 cooperates with the locking screw 72, so that the inner wall of the locking screw 72 is tightly attached to the outer wall of the optical fiber 6, and the optical fiber 6 after the angle is adjusted is fixed in the locking screw 72.

[0042] Among them, a groove 12 is opened on the locking screw 72. When the locking nut 8 is screwed onto the locking screw 72, the groove 12 shrinks under the squeezing force of the locking nut 8 wrapping around the locking screw 72, so that the inner wall of the locking screw 72 fits more closely with the outer wall of the optical fiber 6.

[0043] Further, see Figure 4 A threaded hole 13 for inserting a top screw is provided on the outer periphery of the locking nut 8.

[0044] In a possible implementation, in order to ensure the stability of the optical fiber 6 in the connector 5 , a top screw is inserted into the threaded hole 13 , and the end of the top screw abuts against the surface of the optical fiber 6 , which can further limit the position of the optical fiber 6 in the connector 5 .

[0045] In addition, since the outer diameter of the locking nut 8 is relatively small, it is difficult to completely tighten the locking nut 8 onto the locking screw 72 in actual operation. Inserting a top screw in the threaded hole on the locking nut 8 can be used to assist the operator in tightening the locking nut 8 onto the locking screw 72.

[0046] The specific process of the connector alignment device of the present application in actual application is as follows: first, the imaging unit 1, the bracket 2 and the flange 3 are placed in the same horizontal direction, the connector 5 is inserted into the through hole 4 of the bracket 2 and the flange 3, the nut 71 on the connector 5 is rotated, and the connector 5 is fixedly connected to the through hole 4 of the bracket 2 and the flange 3, the optical fiber 6 is rotated, and the image of the end face of the optical fiber 6 on the imaging unit 1 is observed, so that the rectangular core inside the optical fiber 6 is completely horizontal, so as to ensure the accuracy of the axis alignment of the rectangular optical fiber 6 and the connector 5, and the locking nut 8 is rotated so that the locking screw 72 can limit the optical fiber 6, and the optical fiber 6 with the adjusted angle is fixed in the connector 5, and then the top screw is used with thread glue to screw it into the threaded hole 13 of the locking nut 8 to further limit the optical fiber 6, and the axis alignment of the connector 5 and the optical fiber 6 is completed once, and then the nut 71 is separated from the flange 3, and another group of connectors 5 is connected to the bracket 2 and the flange 3, and the next connector 5 and optical fiber 6 are aligned.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
