MPO anti-loosening buckle

Abstract

The utility model relates to an MPO anti-loosening buckle which comprises a lantern ring used for being sleeved on a shell in an MPO connector, a clamping plate is arranged above and / or below the lantern ring, and the middle of the clamping plate is matched with the lantern ring in a rotating mode. And the rear end of the clamping plate is provided with a salient point which can be clamped into a movable groove formed between the rear end of the outer shell and the rear end of an inner shell in the MPO connector and can prevent the outer shell from retreating relative to the inner shell. The MPO connector has the beneficial effects that if the MPO connector is always in a locked state, the clamping plate rotates around the connecting point of the clamping plate and the lantern ring until the convex point is clamped into the movable groove formed between the rear end of the outer shell and the rear end of the inner shell in the MPO connector, and even if the optical fiber patch cord has a certain weight, the MPO connector can be locked. According to the anti-loosening buckle, the phenomenon of loosening between the buckle of the MPO adapter and the MPO connector cannot be caused, and the anti-loosening buckle can be suitable for the existing MPO connector without improving the MPO connector.

Description

Technical Field

[0001] The utility model relates to the technical field of MPO connectors, in particular to an MPO anti-loosening buckle. Background Art

[0002] The MPO connector includes: an outer shell, an inner shell and an optical fiber patch cord. The inner shell is sleeved on the optical fiber patch cord, and the outer shell is movably sleeved on the inner shell. The rear ends of the outer shell and the inner shell both have annular protrusions. When the outer shell moves along its length on the inner shell, a movable groove will be formed between the rear ends of the outer shell and the inner shell. When the MPO connector is inserted into the MPO adapter of the optical module, the outer shell of the MPO connector will block the buckle of the MPO adapter to prevent the buckle of the MPO adapter from being ejected, so as to avoid abnormal position of the optical fiber patch cord and affect performance. However, in actual use, especially when the optical fiber patch cord is relatively long, due to the certain weight of the optical fiber patch cord, it is easy to cause the buckle of the MPO adapter to loosen from the MPO connector. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an MPO anti-loosening buckle to overcome the deficiencies in the above-mentioned prior art.

[0004] The utility model provides a technical solution to the above technical problem as follows: an MPO anti-loosening buckle, comprising: a collar for sleeved on an outer shell of an MPO connector, a card plate arranged above and / or below the collar, a middle portion of the card plate rotatably cooperating with the collar, and a rear end of the card plate having a convex point that can be inserted into a movable groove formed between the rear end of the outer shell and the rear end of an inner shell of the MPO connector and prevent the outer shell from retreating relative to the inner shell.

[0005] On the basis of the above technical solution, the present invention can also be improved as follows.

[0006] Furthermore, the top plate and / or bottom plate of the collar is provided with a notch wider than the gripping plate and used to concede the gripping plate in the front and middle areas corresponding to the gripping plate, and the top plate and / or bottom plate of the collar is provided with a gripping plate respectively above and below the rotating shaft that rotates with the gripping plate in the middle and rear areas corresponding to the gripping plate.

[0007] Furthermore, the collar is symmetrical vertically and horizontally.

[0008] Furthermore, two sides of the collar are in arc shape.

[0009] Furthermore, the side surface of the protrusion close to the rear end of the outer shell is a plane, and the side surface of the protrusion close to the rear end of the inner shell is a plane.

[0010] Furthermore, the surface of the protrusion facing away from the card plate is an arc surface.

[0011] Furthermore, the collar, the clamping plate and the protrusion are made of metal or non-metal material.

[0012] The beneficial effect of the utility model is that during use, the collar of the anti-loosening buckle is sleeved on the outer shell of the MPO connector, and then the MPO connector is inserted into the MPO adapter of the optical module. If the MPO connector is to be kept in a locked state, the card plate is rotated around the connection point between it and the collar, and the convex point is inserted into the movable groove formed between the rear end of the outer shell and the rear end of the inner shell in the MPO connector to prevent the outer shell from retreating relative to the inner shell. At this time, even if the optical fiber jumper has a certain weight, it will not cause the buckle of the MPO adapter and the MPO connector to loosen. In addition, the anti-loosening buckle does not need to be improved on the MPO connector, and can be applied to the existing MPO connector. When the optical fiber jumper of the MPO connector is damaged, the anti-loosening buckle can be removed and used on the next MPO connector, that is, it can be reused.

[0019] 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.

[0020] Example 1

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an MPO anti-loosening buckle includes:

[0022] The collar 1 is used to be sleeved on the housing 410 in the MPO connector 4, and the inner ring cross-sectional size of the collar 1 is smaller than the cross-sectional size of the annular protrusion at the rear end of the housing 410, that is, when the collar 1 is sleeved on the housing 410, the collar 1 will not fall off from the rear end of the housing 410;

[0023] A card plate 2 is arranged above and / or below the collar 1, that is, there are three situations, namely: a card plate 2 is arranged above the collar 1; or a card plate 2 is arranged below the collar 1; or a card plate 2 is arranged above and below the collar 1;

[0024] The middle part of the card plate 2 is rotatably matched with the collar 1, and the rear end of the card plate 2 has a convex point 3, which can be located at the end of the card plate 2 or at the lower / upper surface. For the card plate 2 located above the collar 1, the lower surface has the convex point 3, and for the card plate 2 located below the collar 1, the upper surface has the convex point 3;

[0025] When the card plate 2 rotates around the connection point between it and the collar 1, the protrusion 3 can be inserted into the movable groove 430 formed between the rear end of the outer shell 410 and the rear end of the inner shell 420 in the MPO connector 4;

[0026] During use, the ring 1 of the anti-loosening buckle is put on the shell 410 of the MPO connector 4, and then the MPO connector 4 is inserted into the MPO adapter of the optical module. If the MPO connector 4 is to be kept in a locked state, the card plate 2 is rotated around the connection point between it and the ring 1, and the protrusion 3 is inserted into the movable groove 430 formed between the rear end of the shell 410 and the rear end of the inner shell 420 in the MPO connector 4 to prevent the shell 410 from retreating relative to the inner shell 420. At this time, even if the optical fiber jumper has a certain weight, it will not cause the buckle of the MPO adapter and the MPO connector 4 to become loose. In addition, the anti-loosening buckle does not need to be improved on the MPO connector 4, and can be applied to the existing MPO connector 4. When the optical fiber jumper of the MPO connector 4 is damaged, the anti-loosening buckle can be removed and used on the next MPO connector 4, that is, it can be reused;

[0027] When the protrusion 3 is to be disengaged from the movable groove 430, the front end of the card plate 2 is pressed to rotate the card plate 2 around the connection point between the card plate 2 and the ring 1, so that the rear end of the card plate 2 is tilted, thereby allowing the protrusion 3 to be disengaged from the movable groove 430, thus completing the unlocking.
