Description

Optical fiber capillary structure

Technical Field

The utility model relates to an optic fibre communication accessory field especially relates to an optic fibre capillary structure.

Background

With the rapid development of the optical fiber communication network, a large number of optical devices with high performance and low price are needed, and the optical devices made by packaging optical fibers in capillary tubes have high performance and low price, thereby meeting the rapid development requirements of the optical fiber communication network; the existing capillary tubes are all cylindrical, a through groove is formed in the middle of the capillary tube and used for fixedly connecting optical fibers, the optical fibers are fixed in the capillary tube through glue, and the mounting holes of the capillary tube for accommodating the optical fibers are very small, so that the optical fibers are inconvenient to fixedly insert and are likely to be broken by overlarge force in the inserting process; particularly, after the optical fiber is packaged in the capillary tube, the optical fiber is fixed by glue, and the solidified glue is heated up due to the rise of the external temperature, so that the fixed capillary tube is under the action of various stresses, the strength of the capillary tube is not enough, and the capillary tube is easy to crack.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides an optic fibre capillary structure of intensity height, convenient fixed optic fibre.

The utility model discloses a following technical scheme realizes:

Furthermore, still be equipped with two first convex arc pieces on the last double-layered pipe, two first convex arc piece symmetric distribution is in first grooved left and right sides, first convex arc piece fixed connection be in on the first semicircular groove inner wall.

Furthermore, the lower clamping pipe is further provided with two second convex arc blocks, the two second convex arc blocks are symmetrically distributed on the left side and the right side of the second slot, and the second convex arc blocks are fixedly connected to the inner wall of the second semicircular slot.

Furthermore, the length, height and width of the upper clamping pipe and the lower clamping pipe are the same, the length is 7mm-8mm, the width is 2.5mm-3mm, and the height is 2mm-3 mm.

The utility model has the advantages that:

the optical fiber capillary structure provided by the utility model consists of an upper clamping pipe and a lower clamping pipe, when the optical fiber is fixedly installed, the optical fiber is placed in the semicircular groove, and then the upper and lower clamping pipes are used for clamping the optical fiber, so that the structure is simple and the installation is convenient; when the glue is too much, the glue can flow into the open slot, when the volume of the glue is increased due to thermal expansion after fixation is finished, the upper and lower clamping pipes move up and down a little position due to stress, and the open slot can accommodate a part of the expanded volume, so that the optical fiber capillary structure can not crack due to thermal expansion; the existence of convex arc piece can separate optic fibre and semicircular groove arm a bit space, and more glue can be acceptd in the space, can make optic fibre can be more stable with upper and lower double-layered pipe fixed connection to the convex arc piece can also play the bulk strength that increases the capillary, has strengthened the stress bearing capacity of capillary.

Detailed Description

In order to more clearly and completely explain the technical scheme of the present invention, the present invention is further explained with reference to the attached drawings.

Referring to fig. 1 and 2, the present invention provides an optical fiber capillary structure, which includes an upper clamping tube 10 and a lower clamping tube 15, wherein the upper clamping tube 10 is provided with four fixing posts 11, a first semicircular groove 12 and a first open groove 14, the lower clamping tube 15 is provided with four fixing slots 16, a second semicircular groove 17 and a second open groove 19, the first open groove 14 is communicated with the first semicircular groove 12, the second open groove 19 is communicated with the second semicircular groove 17, when the fixing posts 11 are completely received in the fixing slots 16, the upper clamping tube 10 is fixedly connected with the lower clamping tube 15, and the first semicircular groove 12 and the second semicircular groove enclose 17 to form a circular groove for fixedly receiving optical fibers. Go up to press from both sides and still be equipped with two first protruding arc pieces 13 on the pipe 10, two first protruding arc piece 13 symmetric distribution is in the left and right sides of first fluting 14, first protruding arc piece 13 fixed connection be in on the 12 inner walls of first semicircular groove. Still be equipped with two second protruding arc pieces 18 on the lower clamp 15, two second protruding arc piece 18 symmetric distribution is in the left and right sides of second fluting 19, second protruding arc piece 18 fixed connection be in on the second half slot 17 inner wall.

In the present embodiment, the first semicircular groove 12 and the first convex arc piece 13 have the same axial center, the second semicircular groove 17 and the second convex arc piece 18 have the same axial center, and when the upper clamp pipe 10 and the lower clamp pipe 15 are fixedly connected, the axial centers of the first semicircular groove 12 and the second convex arc piece overlap with each other. The diameters of the first convex arc block 13 and the second convex arc block 18 are just equal to the diameter of the optical fiber, the diameters of the first semicircular groove 12 and the second semicircular groove 17 are slightly larger than the diameter of the convex arc block, so that after the optical fiber is installed in the circular groove, a point gap exists between the optical fiber and the wall of the circular groove, the gap can contain more glue, and the optical fiber can be stably fixed in the circular groove. The first slot 14 and the second slot 19 are used for accommodating glue, and can also prevent the glue from expanding and cracking the capillary due to thermal expansion. Four convex arc blocks are arranged in the whole optical fiber capillary structure, and the convex arc blocks play a role in increasing the structural strength of the optical fiber capillary. When the optical fiber capillary structure is used for fixedly connecting optical fibers, a proper amount of glue is coated on the treated optical fibers, then the optical fibers are placed on the second semicircular groove 17, and then the upper clamping tube 10 and the lower clamping tube 15 are fixed together until the optical fibers and the upper and lower clamping tubes are fixedly connected through the glue.

Furthermore, the length, height and width of the upper clamping tube 10 and the lower clamping tube 15 are the same, the length is 7mm-8mm, the width is 2.5mm-3mm, and the height is 2mm-3 mm.

Of course, the present invention can also have other various embodiments, and based on the embodiments, those skilled in the art can obtain other embodiments without any creative work, and all of them belong to the protection scope of the present invention.
