Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of jigs, and specifically, to an optical fiber jig. Background Art
[0002] At present, in order to reduce the return loss of an optical fiber, the end face of the optical fiber is usually ground to have a certain angle, so as to avoid more reflected light being reflected back to the light source and ensure the optical fiber transmission effect.
[0003] During the grinding process of the optical fiber, several optical fibers are usually clamped on a jig. In order to prevent the clamping of the jig from damaging the optical fiber, optical fiber heads are generally assembled on each optical fiber, so that the clamping force of the jig mainly acts on the optical fiber heads, avoiding damage to the optical fiber due to the clamping force; however, the assembly of the optical fiber and the optical fiber head is usually manually carried out by workers, resulting in deviations in the lengths of the optical fibers passing through the optical fiber heads. Therefore, when the jig clamps each optical fiber by clamping the optical fiber heads, it is easy to occur that the end faces of the optical fibers are not in the same plane, thus affecting the subsequent processing of this batch of optical fibers. For example, during grinding, the grinding effects on each optical fiber are inconsistent, and even some optical fibers cannot be ground by the grinding machine. Summary of the Utility Model
[0004] The utility model provides an optical fiber jig, which solves the problem that the end faces of the optical fibers are not in the same plane when the jig clamps the optical fiber heads on each optical fiber in the related art.
[0005] The technical solution of the utility model is as follows:
[0006] An optical fiber jig includes a base. The base has a detection hole that penetrates the base. An installation disk is arranged in the detection hole. The installation disk is fixedly connected to the base, and the length of the installation disk in the axial direction of the detection hole is less than the axial length of the detection hole. The installation disk has a plurality of installation structures. Each installation structure includes an installation hole and a fixing member for fixing the optical fiber in the installation hole. The installation hole penetrates the installation disk, and the fixing member is threadedly connected to the installation disk.
[0007] Furthermore, the base has a detection hole. The projection of the installation disk on the horizontal plane is a regular polygon structure, the projection of the detection hole on the horizontal plane is a circular structure, and the installation disk is circumscribed with the circumcircle of the detection hole.
[0008] Furthermore, the installation structures are arranged in sequence along the side profile of the installation disk. Fixing holes are provided on one side of each installation hole close to the hole wall of the detection hole, and the fixing member is threadedly connected to the fixing hole.
[0009] Furthermore, the mounting hole has a correction portion, and the correction portion is in a “>”-shaped structure on a horizontal projection surface. The correction portion and the fixing member are respectively located on two sides of the mounting hole.
[0010] Furthermore, the base is provided with a plurality of legs, and a second base is provided below the mounting plate, and the second base is detachably connected to the mounting plate.
[0011] Furthermore, a positioning hole is provided at one end of the installation plate close to the second base, and a positioning column for cooperating with the positioning hole is provided on the second base.
[0012] The working principle and beneficial effects of the utility model are:
[0013] The base of the utility model is provided with a detection hole, a mounting plate is provided in the detection hole, and a plurality of mounting structures are provided on the mounting plate so that the optical fiber equipped with the optical fiber head can be mounted on the mounting plate;
[0014] Each mounting structure includes a mounting hole and a fixing piece for fixing the optical fiber in the mounting hole. The fixing piece is threadedly connected to the mounting plate, so that the staff can fix the optical fiber on the mounting plate through the mounting structure, and each mounting hole passes through the mounting plate; and the detection hole should pass through the base, so that when the optical fiber passes through the mounting plate, it can contact with the support surface of the present invention such as the desktop, and the end faces of each optical fiber are placed on the same plane through the support surface, so as to ensure the stability of the subsequent processing procedures of the optical fiber; and, by comparing the height difference between each optical fiber head, the assembly error of the optical fiber head on each optical fiber can be detected, so that each optical fiber can be adjusted so that the present invention can clamp the optical fiber head;
[0015] At the same time, the length of the mounting plate in the axial direction of the detection hole should be smaller than the axial length of the detection hole, that is, the height of the mounting plate is smaller than the height of the base, which reduces the length required for the optical fiber to penetrate the mounting plate, thereby facilitating the optical fiber to penetrate the mounting plate and facilitate the measurement of the optical fiber.

[0026] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.
[0027] As Figure 1 shown, this embodiment proposes an optical fiber fixture, which mainly includes a base 1. The base 1 has a detection hole 11. An installation disc 2 is arranged in the detection hole 11. The installation disc 2 has a plurality of installation structures 21. That is, the optical fiber is installed on the installation disc 2 by means of the installation structure 21. At the same time, the installation disc 2 is fixedly connected to the base 1 to prevent the installation disc 2 equipped with a plurality of optical fibers from falling off the base 1;
[0028] As Figure 3 , Figures 6 to 7 shown, each installation structure 21 in this embodiment includes an installation hole 211 and a fixing part 212 for fixing the optical fiber in the installation hole 211. The installation hole 211 penetrates through the installation disc 2, and the detection hole 11 penetrates through the base 1, so that when the optical fiber is inserted into the installation hole 211, one end of the optical fiber can be abutted against a supporting surface such as a desktop; and by means of this abutting relationship, the end faces of the optical fibers are all in the same plane; at this time, by comparing the height differences between the optical fiber heads assembled on each optical fiber, it can be clearly known which optical fiber heads on which optical fibers have large assembly errors, so that the staff can make adjustments accordingly, so as to ensure that the clamping force of the installation structure 21 can accurately act on the optical fiber heads;
[0029] The fixing member 212 is threadedly connected to the mounting plate 2 , that is, the fixing member 212 can be moved in a linear direction by rotating the fixing member 212 , thereby cooperating with the wall of the mounting hole 211 to fix the optical fiber, thereby facilitating the staff to fix the optical fiber in the mounting hole 211 .
[0030] Moreover, the length of the mounting plate 2 in the axial direction of the detection hole 11 is smaller than the axial length of the detection hole 11, that is, the height of the mounting plate 2 is smaller than the height of the base 1, which reduces the length required for the optical fiber to penetrate the mounting plate 2 in disguise, thereby facilitating the optical fiber to penetrate the mounting plate 2 and facilitating the optical fiber measurement work in this embodiment.
[0031] At the same time, considering that the surface of the desktop as the support surface of this embodiment may be uneven, resulting in that the optical fibers are not actually on the same plane after abutting the desktop, therefore, Figures 4 to 5 As shown, a second base 3 is provided below the mounting plate 2 in this embodiment. When the plane for contacting the optical fibers with the second base 3 is ensured to be flat, the optical fibers can be ensured to be in contact with the second base 3 to ensure that the end faces of the optical fibers are in the same plane, thereby ensuring the accuracy when comparing the height differences of the optical fiber heads. The base 1 is provided with a plurality of legs 12 to raise the horizontal height of the base 1, so that the second base 3 can be arranged below the base 1 for coordinated measurement with the optical fibers. The second base 3 is detachably connected to the mounting plate 2, so that the staff can decide whether to use the second base 3 according to the actual support surface, thereby improving the accuracy of the present invention. The flexibility of the embodiment is that when the second base 3 is not used, there is a gap between the bottom of the base 1 and the supporting surface, which is convenient for the staff to check whether each optical fiber is abutting against the contact surface; similarly, a certain gap is also retained between the bottom of the base 1 and the top of the second base 3, so that when the base 1 is used in conjunction with the second base 3, it is convenient for the staff to check whether each optical fiber is abutting against the second base 3, so that when using this embodiment, the staff can detect whether each optical fiber is fully abutting against the supporting surface, thereby ensuring the accuracy of the relative position of each optical fiber head when comparing the height difference of each optical fiber head, thereby ensuring the accuracy of the final measurement result.
[0032] like Figure 1 , Figure 3As shown, the projection of the mounting disc 2 in this embodiment on the horizontal plane has a regular polygon structure, and the projection of the detection hole 11 on the horizontal plane has a circular structure. The mounting disc 2 is arranged circumscribing the detection hole 11, so that the edge of the mounting disc 2 is in contact with the hole wall of the detection hole 11, which can effectively disperse the load and improve the stability and strength of the overall structure of this embodiment. Moreover, regarding how the mounting disc 2 and the base 1 in this embodiment are fixedly connected, it is preferably to provide a plurality of connecting rods on the base 1, and each connecting rod is threadedly fixed on the base through threaded parts such as bolts, and the mounting disc 2 is also threadedly fixed to each connecting rod through bolts. That is, the fixed connection between the mounting disc 2 and the base 1 in this embodiment is preferably realized through a detachable fixed connection method. So that later the staff can remove the mounting disc 2 from the base 1 and directly send each optical fiber fixed on the mounting disc 2 and the mounting disc 2 itself into the next optical fiber processing process.
[0033] One end of the mounting disc 2 close to the second base 3 is provided with a positioning hole 22, and the second base 3 is provided with a positioning post 31 for cooperating with the positioning hole 22. Through the cooperation between the positioning post 31 and the positioning hole 22, the positional relationship between the mounting disc 2 and the second base 3 can be quickly found; at the same time, with the circumscribed circle setting between the mounting disc 2 and the detection hole 11, the positioning of the mounting disc 2 on the base 1 can be quickly realized. The three cooperate with each other to realize the rapid assembly of this embodiment and ensure the practicability of this embodiment.
[0034] As Figures 1 to 3 As shown, each mounting structure 21 in this embodiment is arranged in sequence along the side profile of the mounting disc 2, so as to ensure the uniformity of the distribution of each mounting structure 21 on the mounting disc 2; moreover, distributing each mounting structure 21 along the outer contour of the polygon can not only effectively increase the stability of the overall structure of this embodiment, but also facilitate optimizing the layout of each mounting structure 21 according to the use requirements, such as reducing or increasing the number of mounting structures 21, so as to achieve the best layout effect while ensuring the space utilization rate and ensure the practicability of this embodiment. One side of each mounting hole 211 close to the hole wall of the detection hole 11 is provided with a fixing hole 213, and each fixing member 212 is threadedly connected to each fixing hole 213 in one-to-one correspondence. In this way, on the premise of meeting the cooperation requirements between each mounting hole 211 and each fixing member 212, the spiral stroke of each fixing member 212 is greatly reduced, so that the staff can fix the optical fiber through each mounting structure 21.
[0035] Moreover, the mounting hole 211 has a calibration portion 2111. The calibration portion 2111 has a ">"-shaped structure on the horizontal plane projection surface. The opening direction of the calibration portion 2111 faces the position of the central axis of the mounting hole 211, so that the calibration portion 2111 forms a positioning triangular structure on the side wall of the mounting hole 211. And the calibration portion 2111 and the fixing member 212 are respectively located on both sides of the mounting hole 211. That is, under the clamping and pushing action of the fixing member 212, the fiber optic head assembled on the optical fiber will contact the calibration portion 2111 under the push of force, and thus move to the designated position under the guiding action of the calibration portion 2111 to complete the positioning. This ensures the spacing between the optical fibers fixed on the mounting disc 2 and facilitates the processing of each optical fiber in the next process step.
[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
