Description
Technical Field
The utility model relates to a capillary 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;
at present, optical fibers are fixed in a capillary tube through glue, a mounting hole of the capillary tube for accommodating the optical fibers is very small, if the glue left in the capillary tube is too much due to improper operation of workers, the mounting hole is filled with the glue, after the glue is solidified, the outside temperature rises, the solidified glue is hot-expanded, the volume of the solidified glue is increased, the capillary tube is burst, and then an optical device is damaged.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model provides an optic fibre capillary structure with hole is accomodate to glue.
The utility model discloses a following technical scheme realizes:
the utility model provides an optical fiber capillary structure, optical fiber capillary structure includes entry site and main part, entry site with main part fixed connection, be equipped with the horn hole in the entry site, the horn hole runs through entry site, the main part is equipped with the mounting hole, the mounting hole runs through the main part, the mounting hole with the horn hole intercommunication, the junction of entry site and main part is equipped with the inclined plane, the inclined plane is 13 degrees with the contained angle of water flat line; the main body part is further provided with an accommodating hole communicated with the mounting hole, and the accommodating hole penetrates through the main body part.
Further, the shapes of the inlet part and the main body part are regular hexagonal prisms.
Further, the trumpet hole and the mounting hole are concentric holes.
The utility model has the advantages that:

Detailed Description
For a more clear and complete description of the technical solution of the present invention, the following description is made with reference to the accompanying drawings.
Referring to fig. 1 and 2, the present invention provides an optical fiber capillary structure, which includes an inlet portion 10 and a main body portion 20, wherein the inlet portion 10 is fixedly connected to the main body portion 20, a horn hole 11 is disposed in the inlet portion 10, the horn hole 11 penetrates through the inlet portion 10, the main body portion 20 is provided with a mounting hole 21, the mounting hole 21 penetrates through the main body portion 20, the mounting hole 21 is communicated with the horn hole 11, a connection portion between the inlet portion 10 and the main body portion 20 is provided with an inclined plane 30, and an included angle between the inclined plane 30 and a horizontal line is 13 degrees; the main body part 20 is further provided with an accommodating hole 22 communicated with the mounting hole 21, and the accommodating hole 22 penetrates through the main body part 20; the trumpet hole 11 and the mounting hole 21 are concentric holes.
In this embodiment, the inclined plane 30 is disposed at the connection between the inlet portion 10 and the main body portion 20, and an included angle between the inclined plane 30 and a horizontal line is 13 degrees, so that liquid can rapidly flow back into the bell hole 11 through the inclined plane 30; when the external optical fiber is installed in the optical fiber capillary structure, the external optical fiber is covered with glue, the external optical fiber enters the installation hole 21 through the flared hole 11, and due to the small diameter of the installation hole 21, the glue on the surface of the external optical fiber is partially accumulated at the connection position of the inlet portion 10 and the main body portion 20 when entering the installation hole 21, and the accumulated glue can quickly flow back into the flared hole 11 through the inclined surface 30, so that the glue is prevented from being excessively accumulated at the connection position of the inlet portion 10 and the main body portion 20; after the external optical fiber enters the mounting hole 21, because the diameter of the mounting hole 21 is very small, the mounting hole 21 is filled with glue quickly, and at the moment, the glue can partially flow into the accommodating hole 22 to ensure that the mounting hole 21 cannot be completely filled with the glue, so that the mounting hole 21 has a certain redundant space, and after the glue is solidified, even if the volume of the solidified glue is increased due to the rise of external temperature, the optical fiber capillary structure cannot be broken.
Further, the inlet portion 10 and the body portion 20 are each shaped like a regular hexagonal prism.
In this embodiment, the shapes of the inlet portion 10 and the main body portion 20 are regular hexagonal prisms, that is, the optical fiber capillary structure is a regular hexagonal prism, and compared with a conventional cylindrical capillary, the optical fiber capillary structure is easier to be fastened and clamped by a clamp, and is more convenient to use.
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.
