Embodiment 1

[0056] This embodiment provides a reusable fixed structure, such as Figure 3 to Figure 6 As shown, it includes a fixed body 4 made of a material with a high coefficient of friction. The fixed body 4 includes an insertion portion 41 and a balance portion 42 disposed on one end surface 21 of the insertion portion 41 .

[0057] see Figure 5 and Figure 6 , the balance part 42 is provided with an insertion hole 43, and the insertion hole 43 extends along the length direction of the fixed body 4; the insertion part 41 is provided with a groove 44 communicating with the insertion hole 43, and the two sides of the groove 44 are connected to the The outside world is connected, that is, the groove 44 separates the insertion part 41 into upper and lower parts. The axis of the insertion hole 43 coincides with the axis of the groove 44, and the object to be fixed passes through the groove 44 and the insertion hole 43. When the insertion part 41 squeezes the object to be fixed, the ax...

Embodiment 2

[0065] This embodiment provides a reusable fixed structure, such as Figure 7 to Figure 10 As shown, the difference between it and the fixing structure in Embodiment 1 is that the outer contours of the socket part 41 and the balance part 42 are both cylindrical, and the outer wall of the fixed body 4 on the side of the groove 44 is provided with a The wedge groove 45 extending from the insertion part 41 has a bottom of an arc surface, and the depth of the wedge groove 45 gradually becomes shallower from the balance part 42 to the insertion part 41 . The end of the wedge groove 45 extends to the middle of the insertion portion 41 and is located above the groove 44 , so that the insertion portion 41 is pressed down through the groove 44 after the wedge is inserted into the wedge groove 45 .

[0066] see Figure 10 , the groove wall of the groove 44 on the side where the wedge groove 45 is located is recessed outwards to form an arc wall 46 , and the arc wall 46 coincides with t...

Embodiment 3

[0073] This embodiment provides a reusable fixed structure, such as Figure 11 to Figure 14 As shown, the difference between it and the fixing structure provided in Embodiment 1 and Embodiment 2 is that: the groove 44 is arranged on the balance part 42, and the groove 44 separates the balance part 42 into upper and lower parts; the insertion hole 43 is arranged on on the socket part 41.

[0074] see Figure 13 and Figure 14 The outer contours of the balance part 42 and the socket part 41 are cylindrical, and the diameter of the balance part 42 is greater than the diameter of the socket part 41; one side of the groove 44 is recessed outwards to form an arc wall 46, and the arc The wall 46 coincides with the extension surface of the hole wall of the insertion hole 43 . The outer diameter of the insertion part 41 is slightly smaller than the inner diameter of the insertion hole, so as to ensure that the insertion part 41 can be inserted into the insertion hole.

Abstract

The invention provides a reusable fixing structure which comprises a fixing body. The fixing body is made of a substance with a high friction coefficient, and the fixing body comprises an inserting part and a balancing part. During use, a to-be-fixed object is extruded through the inserting part or the balancing part and is fixed through friction force between the inserting part and the balancing part. When the to-be-fixed object is the bare fiber, the end face of the bare fiber is manufactured, and various performance tests of the laser are completed, the optical fiber does not need to be cut off, the flat end face of the optical fiber cannot be damaged, the optical fiber does not need to be discarded, length reduction caused by repeated manufacturing of the end face of the optical fiber can be avoided, and materials are saved. In the inserting process, the outer wall of the bare fiber abuts against and is fixed to the inner wall face of the inserting hole, and the bare fiber can be prevented from inclining in the inserting process. Meanwhile, the reusable fixing structure of the structure is used for fixing the bare fiber, and an ultraviolet lamp and ultraviolet curing glue are not needed; and the fixing structure can be repeatedly used, so that the material cost is saved. And the bare fiber is fast to install and fix without waiting for curing of the ultraviolet curing glue.

Description

technical field [0001] The invention relates to the technical field of optical fiber fixing equipment, in particular to a reusable fixing structure. Background technique [0002] The energy inside the semiconductor laser is output through the optical fiber. The current optical fiber output end will use different optical fiber output methods due to different applicable products. Among them, semiconductor lasers that output in the form of bare optical fibers need to test various performances of semiconductor lasers during the production process of semiconductor lasers. The test instrument is connected through a bare optical fiber located outside the semiconductor laser to output the energy of the semiconductor laser to the test instrument. For the test instrument, the bare optical fiber needs to have the following properties: the end face of the output end of the optical fiber is a smooth plane; both the fixed fiber and the output end of the optical fiber are fixed. Therefor...
