Description

Technical Field

[0001] The utility model relates to the technical field of repairing optical fiber collimators, in particular to an optical fiber collimator with a cooling function. Background Art

[0002] Collimator is an optical element used for input and output of optical fiber communication devices. Its structure is very simple - the divergent light from the optical fiber is converted into parallel light through a convex lens in front. Its function is to make the light coupled into the required device with maximum efficiency or to receive the optical signal with maximum efficiency. Therefore, it has an important parameter: insertion loss, and the process technology can reach less than 0.15dB.

[0003] Generally speaking, due to the multiple scattering of electrons in the air and the inevitable scattering of the beam limiter wall, the collimation of the electron beam cannot be simply treated as a ray geometry problem. The cross section of the electron radiation beam coming out of the beam limiter is generally significantly larger than the geometric electron beam cross section, in order to achieve a dynamic balance between the electrons scattered in and out of the edge of the electron beam.

[0004] During the process of fiber conversion by the fiber collimator, it may overheat due to the long conversion time. However, the fiber collimator is an integrated structure, which is difficult to disassemble and dissipate in time, and the actual cooling effect cannot be achieved. Therefore, overheating may cause the fiber conversion effect to deteriorate, making it difficult to efficiently cool the fiber collimator. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes an optical fiber collimator with a cooling function.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An optical fiber collimator with a cooling function comprises an optical fiber collimator body, a sealing sleeve is arranged at the bottom of the optical fiber collimator body, and a cooling mechanism is arranged between the optical fiber collimator body and the sealing sleeve;

[0008] The cooling mechanism is provided with spiral grooves in the middle of both sides of the exterior, and heat dissipation holes are provided through the inner wall of the cooling mechanism between the two sides of the spiral grooves, and bumps are provided inside the optical fiber collimator body corresponding to the spiral grooves.

[0009] In addition, a preferred structure is that the top of the optical fiber collimator body is connected to a threaded connection part through threaded rotation, and an observation tube is installed on the top of the threaded connection part.

[0010] In addition, a preferred structure is that a collimating mechanism is provided at the bottom of the sealing sleeve, a fixing part is provided directly below the collimating mechanism, and a spherical convex mirror is provided inside the collimating mechanism.

[0011] In addition, a preferred structure is that when the optical fiber collimator body is rotated through the rotation groove to maintain a certain height with the sealing sleeve, the heat dissipation holes opened on the cooling mechanism can be fully exposed.

[0012] In addition, a preferred structure is that the observation tube and the bottom end of the spherical convex mirror are in the same straight line, and the convex surface of the spherical convex mirror is always facing downward.

[0013] In addition, a preferred structure is that the protrusion inside the optical fiber collimator body and the spiral groove provided outside the cooling mechanism are adapted to each other, and the bending angles are consistent.

[0014] In addition, a preferred structure is that when the heat dissipation holes on the cooling mechanism are in a fully open state, the optical fiber collimator body is separated from the sealing sleeve.

[0015] The beneficial effects of the utility model are as follows: by quickly disassembling the fiber optic collimator body, the hot air retained in the fiber optic collimator can be quickly discharged, and then by the cooperation of the protrusion and the rotating groove, the heat dissipation holes on the cooling mechanism can be quickly exposed and sealed, thereby achieving rapid heat dissipation and sealing of the fiber optic collimator, making the cooling of the fiber optic collimator more efficient and rapid.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 , an optical fiber collimator with cooling function, comprising an optical fiber collimator body 1, a sealing sleeve 4 is arranged at the bottom of the optical fiber collimator body 1, and a cooling mechanism 7 is arranged between the optical fiber collimator body 1 and the sealing sleeve 4;

[0024] A spiral groove 9 is provided in the middle of both sides of the cooling mechanism 7 , and a heat dissipation hole 8 is provided between both sides of the spiral groove 9 and through the inner wall of the cooling mechanism 7 , and a protrusion 10 is provided inside the optical fiber collimator body 1 corresponding to the spiral groove 9 .

[0025] The top of the fiber optic collimator body 1 is connected to a threaded connection part 2 by threaded rotation, and an observation tube 3 is installed on the top of the threaded connection part 2. The observation tube 3 is used to observe the correction status of the fiber optic collimator.

[0026] In addition, a collimating mechanism 6 is provided at the bottom of the sealing sleeve 4, and a fixing part 5 is provided directly below the collimating mechanism 6, and a spherical convex mirror 61 is provided inside the collimating mechanism 6, and the spherical convex mirror 61 is used to correct the optical fiber.

[0027] When the fiber collimator body 1 is rotated through the rotation groove 9 to maintain a certain height with the sealing sleeve 4, the heat dissipation holes 8 opened on the cooling mechanism 7 can be fully exposed. When the heat dissipation holes 8 can be fully exposed, the cooling effect of the fiber collimator will be better.

[0028] The bottom end of the observation tube 3 and the spherical convex mirror 61 are in the same straight line, and the convex surface of the spherical convex mirror 61 is always facing downward. At the same time, the protrusion 10 inside the fiber optic collimator body 1 and the spiral groove 9 opened outside the cooling mechanism 7 are adapted to each other, and the bending angles are consistent.

[0029] Moreover, when the heat dissipation holes 8 on the cooling mechanism 7 are in a fully open state, the optical fiber collimator body 1 and the sealing sleeve 4 are separated.

[0030] In this embodiment, first, during the process of optical fiber alignment in the optical fiber collimator body 1, a high temperature environment will be formed at the spherical convex mirror 61 due to the accumulation of optical fibers, and over time, overheating will occur during the alignment process, affecting the correction effect.

[0031] After the correction effect is affected, the fixing part 5 at the bottom of the optical fiber collimator body 1 is first fixed, and then the upper part of the optical fiber collimator body 1 is taken out, so that the optical fiber collimator body is in an exposed state.

[0032] Then the fiber optic collimator body 1 is rotated clockwise so that the protrusion 10 inside the fiber optic collimator body 1 is rotated out along the rotation groove 9, so that the heat dissipation hole 8 on the cooling mechanism 7 on the top of the sealing sleeve 4 is exposed, so that the hot air remaining in the fiber optic collimator body 1 can be quickly discharged to achieve a cooling effect, and during the exhaust process, the hot air will not rush to the spherical convex mirror 61, causing the lens of the spherical convex mirror 61 to be worn.

[0033] In the utility model, the hot air retained in the optical fiber collimator 1 can be quickly discharged by quickly disassembling the main body of the optical fiber collimator 1, and then the heat dissipation holes 8 on the cooling mechanism 7 can be quickly exposed and sealed through the cooperation of the protrusion 10 and the rotating groove 9, thereby realizing the rapid heat dissipation and sealing of the optical fiber collimator, making the cooling of the optical fiber collimator more efficient and rapid.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
