[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] Example 1

[0028] like Figures 1 to 6 As shown, an MPO anti-loosening buckle includes: a U-shaped buckle 1 and a lock buckle 2. The opening size of the U-shaped buckle 1 meets the requirements for insertion into the slide slot in the MPO, and its width is also adapted to the width of the slide slot in the MPO. The two ends of the lock buckle 2 are respectively engaged with the two ends of the opening end of the U-shaped buckle 1.

[0029] When the MPO (fiber optic connector) is vertically inserted into the adapter of the optical module, the U-shaped buckle 1 is vertically distributed and inserted into the slide groove in the MPO;

[0030] The lock buckle 2 has a hole 210 for inserting an external tool and serving as a force application point to release the lock buckle 2 from the U-shaped buckle 1;

[0031] In this solution, the external tool can be a retractor, such as Figure 6 As shown, one end of the hook is hooked into the hole 210, and then force is applied to release the locking state of the lock buckle 2 and the U-shaped buckle 1, that is, the lock buckle 2 and the U-shaped buckle 1 are separated. Of course, other types of external tools, such as ropes, are not excluded;

[0032] When the U-shaped buckle 1 is inserted into the slide groove in the MPO and the U-shaped buckle 1 is engaged with the lock buckle 2, the outer shell in the MPO can be prevented from sliding backward. Therefore, even if the optical fiber jumper has a certain weight, it is not easy to cause the adapter buckle to loosen from the MPO. If maintenance is required, an external tool is inserted into the hole 210 and force is applied to release the lock buckle 2 and the U-shaped buckle 1 from the engaged state, thereby separating and removing the lock buckle 2 and the U-shaped buckle 1 from the MPO. The structure is simple and easy to engage, which is easier than using hands to release the engaged state.

[0033] Example 2

[0034] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 As shown, this embodiment is a further improvement on the basis of embodiment 1, specifically as follows:

[0035] A first boss 220 is provided on the middle portion of the outer side surface of the lock buckle 2, and a hole 210 is provided on the first boss 220. The hole 210 is provided on the first boss 220 to prevent the lock buckle 2 from breaking when unlocked with the help of an external tool. Since the hole 210 is provided on the first boss 220, the hole 210 provided on the first boss 220 can be a complete hole or have a notch on the side. If there is a notch, then a hole 210 can be provided on each side of the first boss 220, or only one hole can be provided.

[0036] Furthermore, there is an arc-shaped transition surface between the two sides of the first protrusion 220 and the outer side surface of the lock buckle 2.

[0037] Example 3

[0038] like Figure 1 、 Figure 2 、 Figure 3 As shown, this embodiment is a further improvement on the basis of embodiment 1 or 2, specifically as follows:

The two first protrusions 110 on the U-shaped buckle 1 are respectively inserted into the two first bayonet holes 230 on the lock buckle 2 to allow the U-shaped buckle 1 and the lock buckle 2 to be connected. It is easy to assemble, has a simple structure and good stability.

[0040] The inner sides of the two side arms of the U-shaped buckle 1 are provided with a receiving groove 120 for accommodating the second boss 311 on the inner shell 310 of the MPO3. The U-shaped buckle 1 has a better fit with the MPO3, and it can be applied to both the MPO3 with the second boss 311 on the inner shell 310 and the MPO3 without the second boss 311 on the inner shell 310, and has good versatility.

[0041] Example 4

[0043] The two side arms of the U-shaped buckle 1 are provided with second bayonet holes 130 at the ends. The lock buckle 2 is also a U-shaped structure, and the inner sides of the two side arms of the lock buckle 2 are provided with second protrusions 240. The two second protrusions 240 on the lock buckle 2 are respectively inserted into the two second bayonet holes 130 on the U-shaped buckle 1 to allow the lock buckle 2 to be snapped together with the U-shaped buckle 1. It is easy to assemble, has a simple structure and good stability. The snap-fitting structure described in Example 4 is exactly opposite to the snap-fitting structure described in Example 3.

[0044] In addition, each side arm end of the U-shaped buckle 1 has an inwardly recessed groove 140 on the outer surface, and the second snap-in opening 130 is located in the inwardly recessed area of ​​the side arm. When the lock buckle 2 is snap-fitted with the U-shaped buckle 1, the groove 140 can accommodate the mating sections of the lock buckle 2 and the U-shaped buckle 1.

[0045] The inner sides of the two side arms of the U-shaped buckle 1 are provided with a receiving groove 120 for accommodating the second boss 311 on the inner shell 310 of the MPO3. The U-shaped buckle 1 has a better fit with the MPO3, and it can be applied to both the MPO3 with the second boss 311 on the inner shell 310 and the MPO3 without the second boss 311 on the inner shell 310, and has good versatility.

[0046] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
