Description

Technical Field

[0001] The utility model relates to the technical field of optical modules, in particular to an MPO anti-loosening pull ring and an optical module. 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 pull ring and an optical module 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 pull ring, comprising: a U-shaped handle and connecting pieces respectively connected to the two ends of the U-shaped handle, the inner sides of the two arms of the U-shaped handle are provided with a stop for preventing the outer shell of the MPO connector from retreating relative to the inner shell after the MPO connector is inserted into the MPO adapter of the optical module.

[0005] The beneficial effect of the utility model is that when the MPO connector is inserted into the MPO adapter of the optical module, the stop position on the pull ring of the optical module can prevent the outer shell of the MPO connector from retreating relative to the inner shell. Therefore, even if the optical fiber jumper of the MPO connector has a certain weight, it will not cause the buckle of the MPO adapter to loosen with the MPO connector, thereby preventing the optical fiber jumper of the MPO connector from being abnormal and affecting the performance.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the end of the stop extending toward the MPO connector does not exceed the outer wall of the inner shell.

[0008] The above further beneficial effect is that the U-shaped handle can be prevented from being pushed out by the stopper and exceeding the agreement. Further, the stopper is a convex block, and the convex block is located in the movable groove formed between the rear end of the outer shell and the rear end of the inner shell in the MPO connector.

[0009] Furthermore, the side of the protrusion facing away from the connecting member is an inclined guide surface, and the side of the protrusion facing away from the connecting member is a plane.

[0010] Furthermore, the protrusion and the U-shaped handle are integrally formed.

[0011] Furthermore, the protrusions are in the shape of long strips and are distributed along the height direction of the U-shaped handle.

[0012] Based on the above technical solution, the utility model also provides an optical module, including the above MPO anti-loosening pull ring.

[0013] A further beneficial effect of the above is that when the optical module is plugged into the MPO connector, the optical fiber jumper of the MPO connector can be prevented from being abnormal, so as not to affect the performance. BRIEF DESCRIPTION OF THE DRAWINGS

[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 As shown, an MPO anti-loosening pull ring comprises: a U-shaped handle 1 and a connecting piece 2 respectively connected to two ends of the U-shaped handle 1, and a stop 3 is provided on the inner side of the two arms of the U-shaped handle 1 to prevent the outer shell 410 of the MPO connector 4 from retreating relative to the inner shell 420 after the MPO connector 4 is inserted into the MPO adapter of the optical module 5;

[0022] When the MPO connector 4 is inserted into the MPO adapter of the optical module, the stop 3 on the pull ring of the optical module will prevent the outer shell 410 in the MPO connector 4 from retreating relative to the inner shell 420. Therefore, even if the optical fiber jumper of the MPO connector 4 has a certain weight, it will not cause the buckle of the MPO adapter to loosen with the MPO connector 4, thereby preventing the optical fiber jumper of the MPO connector 4 from being abnormal and affecting the performance.

[0023] Example 2

[0024] like Figure 1 , Figure 2 As shown, this embodiment is a further improvement on the basis of embodiment 1, and the details are as follows:

[0025] The end of the stopper 3 extending toward the MPO connector 4 does not exceed the outer wall of the inner shell 420, which can prevent the U-shaped handle 1 from being pushed out by the stopper 3 and exceeding the agreement.

[0026] Example 3

[0027] like Figure 1 , Figure 2 As shown, this embodiment is a further improvement on the basis of embodiment 2, and the details are as follows:

[0028] The gear position 3 is a protrusion, which is located in a 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. The structure is relatively simple. The protrusion is located in the movable groove 430, which can effectively prevent the outer shell 410 in the MPO connector 4 from retreating relative to the inner shell 420.

[0029] Furthermore: the side of the protrusion facing away from the connector 2 is an inclined guide surface, and the side facing away from the connector 2 is a plane. The guide surface can play a guiding role, thereby facilitating the insertion of the MPO connector 4 into the MPO adapter of the optical module.

[0030] The protrusion is integrally formed with the U-shaped handle 1 , and the protrusion can be formed together when the U-shaped handle 1 is produced, thereby simplifying the processing steps.

[0031] The protrusions are in the shape of long strips and are distributed along the height direction of the U-shaped handle 1 , so that the protrusions and the housing 410 have sufficient contact surface to ensure stability.

[0032] In the actual design process, the gear position 3 does not exclude the use of other structures, such as a spring, or a pin that runs through the two arms of the U-shaped handle 1, etc.

[0033] Example 4

[0034] like Figure 3 As shown, an optical module includes the MPO anti-loosening pull ring as described in Example 1, 2 or 3.

[0035] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
