A limiting protrusion is provided on the rotating terminal. Two through holes are provided on the rotating terminal. When installing an optical fiber, the fixed terminal is fixed and the limiting protrusion is used in cooperation, so that the fixed terminal can be locked more precisely. After the direction of the axis connection line of the two through holes is fixed to a specified position, the optical fiber is aligned with the through holes and inserted, and then glue is used in cooperation to fix the optical fiber to the terminal.

The metal sheet is in precise cooperation with the terminal in the initial state. After a long time, the wear of the metal sheet is relatively large, resulting in slight shaking when the terminal is plugged into the metal sheet, which affects the fixing accuracy of the terminal and needs to be improved urgently.

Detailed implementation manners

[0033] The following further elaborates on the present application in conjunction with the attached Figures 1 - 3 drawings.

[0034] Embodiment 1 of the present application discloses a polarization-maintaining connection four-axis alignment clamping device.

[0035] Embodiment 1

[0036] Referring to Figure 1 , a polarization-maintaining connection four-axis alignment clamping device includes a metal sheet 1. A first deformation cavity 7 is formed on the metal sheet 1. A first clamping piece 2 is integrally formed in the first deformation cavity 7. The first clamping piece 2 is in a C shape, and a gap is formed between the first clamping piece 2 and the side wall of the first deformation cavity 7. The two first clamping pieces 2 approach each other to clamp the rotating terminal, achieving the purpose of limiting the terminal. A second deformation cavity 10 is formed on the metal sheet 1. A second clamping piece 5 is integrally formed in the second deformation cavity 10. The second clamping piece 5 and the side wall of the second deformation cavity 10 form a first deformation cavity 9. The second clamping pieces 5 approach each other to clamp the limiting convex block. With such a design, by clamping the rotating terminal with the first clamping piece 2 and cooperating with the second clamping piece 5 to clamp the limiting convex block, the overall terminal can be fixed more stably.

[0037] Two second deformation cavities 11 are formed on the metal sheet 1. The second deformation cavities 11 are cylindrical. The second deformation cavities 11 are communicated with the first deformation cavity 9 and are formed near the connection position of the second clamping piece 5 and the metal sheet 1. The second deformation cavities 11 are used to reduce the thickness at the connection position of the second clamping piece 5 and the metal sheet 1. Thus, the second clamping piece 5 can better clamp the limiting convex block.

[0038] Connecting plates 6 are provided on the two opposite side walls of the second deformation cavity 10. The connecting plates 6 are rectangular plates. The second clamping piece 5 is integrally formed on the connecting plates 6, thereby increasing the length of the end of the second clamping plate from the metal sheet 1, thus better increasing the movement space and elasticity of the second clamping plate, and making the limiting convex block more stable.

[0039] An auxiliary clamping plate 3 is fixed on the first clamping piece 2. The two auxiliary clamping plates 3 are used to clamp the rotating terminal, increasing the contact area between the first clamping piece 2 and the rotating terminal, so as to clamp the rotating terminal more stably. A first chamfer 4 for facilitating the insertion of the rotating terminal is provided at the top of the auxiliary clamping plate 3. Second chamfers 8 for facilitating the insertion of the limiting protrusions are provided on both sides of the two second clamping pieces close to each other.

[0040] The implementation principle of a polarization-maintaining connection four-axis alignment clamping device according to an embodiment of the present application is as follows: The rotating terminal is inserted between the two first clamping pieces 2, and at the same time, the limiting protrusion is inserted between the two first clamping pieces 2, thus completing the fixation of the rotating terminal. Under the action of the elastic first clamping piece 2 and the second clamping piece 5, the rotating terminal and the limiting protrusion can always be kept in a pressed state, greatly improving the stability of the fixation of the rotating terminal.

[0041] Embodiment 2

[0042] Refer to Figure 2 In this embodiment, the difference from Embodiment 1 is that an elastic member 15 is fixed between the first clamping piece 2 and the side wall of the second deformation cavity 10. The elastic member 15 is a compression spring. The elastic member 15 is used to drive the two first clamping pieces to approach each other, so as to clamp the rotating terminal more stably. A plugging groove is provided on the metal side wall, and a plugging bolt 12 is in threaded fit connection in the plugging groove. The plugging bolt 12 is inserted into the middle position of the compression spring, so as to play a role in limiting the elastic member 15 and improving the stability of the elastic member 15. A limiting hole 13 in plugging fit with the elastic member 15 is provided on one side of the first clamping piece 2 close to the elastic member 15. The limiting hole 13 is a round hole, so as to prevent the spring from moving.

[0043] Refer to Figure 3 In, a friction groove 14 is provided on the side of the auxiliary clamping plate 3 away from the first clamping piece 2. The friction groove 14 is spirally provided along the axial direction of the rotating terminal. On the one hand, it can reduce the rotation of the rotating terminal, and on the other hand, it can reduce the rotating terminal from separating from the auxiliary clamping plate 3.

[0044] The implementation principle of Embodiment 2 is as follows: With such a design, the rotating terminal can be fixed more stably through the compression spring and the friction operation, improving the effect of using the clamping device.

[0045] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
