Technical Field

[0001] The utility model relates to the technical field of loop devices, in particular to a remote push-pull shell unlocking loop device. Background Art

[0002] A fiber optic loopback is a small optical device used to connect two optical loops in the same port on a fiber optic device, and to achieve optical loop transmission of optical signals in the device. When an optical communication device fails, a fiber optic loopback can connect the test device and the fiber optic device to transmit the test end optical network signal from the transmitter end to the receiver end, forming a loop for sending and receiving optical signals, and completing the fiber optic loop test.

[0003] Most loopers are provided with a pull-out shell for easy plugging and unplugging, but the existing pull-out shell is a split shell, which is complicated to install, has low installation efficiency, and has high product cost. Therefore, a remote push-pull shell unlocking looper is urgently needed to solve the above problems. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the present utility model embodiment, please refer to Figure 1 and Figure 2A remote push-pull shell unlocking looper includes a ferrule 2 with one end plugged into the optical fiber in the adapter and a bare optical fiber 4 with one end plugged into the other end of the ferrule 2. The ferrule 2 is arranged inside the shell component 1, and the shell component 1 is plugged into the adapter. The other end of the bare optical fiber 4 is connected to a stop body 5, and the stop body 5 is arranged inside the push-pull rear shell 6. The push-pull rear shell 6 includes a fixed end and a push-pull end. The fixed end is connected to the shell component 1, and the push-pull end extends toward the rear end of the ferrule 2.

[0019] Plug the ferrule 2 into the bare optical fiber 4. The ferrule 2 can precisely connect the two end faces of the optical fiber, so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. Insert the ferrule 2 into the shell component 1, place the bare optical fiber 4 and the stopper 5 inside the push-pull rear shell 6, abut the fixed end of the push-pull rear shell 6 against the rear end of the shell component 1, and press the push-pull rear shell 6 to connect the push-pull rear shell 6 and the shell component 1 together. Since the push-pull rear shell 6 has a certain length, when the looper needs to be plugged in and out, the operator can avoid putting his hand into a narrow space to pull the shell component 1, and the plugging and unplugging can be achieved by focusing on the push-pull end of the push-pull rear shell 6, which is convenient and quick, and the service life of the looper is increased.

[0020] As an embodiment of the present invention, please refer to Figure 1 and Figure 2 The fixed end of the push-pull rear shell 6 is symmetrically provided with slots 61, and the fixed end of the push-pull rear shell 6 is symmetrically provided with limit slots 62 on the upper and lower sides; the outer shell assembly 1 is symmetrically provided with protrusions 11 and limit blocks 12 on the upper and lower sides, the protrusions 11 abut against the front end of the limit slot 62, and the limit blocks 12 abut against the rear end of the limit slot 62.

[0021] The fixed end of the push-pull rear shell 6 is abutted against the rear end of the shell assembly 1, and the push-pull rear shell 6 is pressed so that the shell assembly 1 is inserted into the fixed end of the push-pull rear shell 6. During this process, the protrusion 11 and the limit block 12 are inserted into the fixed end of the push-pull rear shell 6. Since the fixed end of the push-pull rear shell 6 is provided with a slot 61, the fixed end of the push-pull rear shell 6 is deformed under the action of the extrusion force and opens to the upper and lower sides. The push-pull rear shell 6 is continued to be pressed. When the shell assembly 1 is inserted into the specified depth, the fixed end of the push-pull rear shell 6 restores its original shape, the protrusion 11 abuts against the front end of the limit groove 62, and the limit block 12 abuts against the rear end of the limit groove 62, so the shell assembly 1 is fixed.

[0022] As an embodiment of the present invention, please refer to Figure 2 The inner wall of the front end of the fixed end of the push-pull rear shell 6 is a bevel structure, which facilitates the connection between the push-pull rear shell 6 and the outer shell assembly 1.

[0023] The inner wall at the front end of the fixed end of the push-pull rear shell 6 is a bevel structure, which facilitates the insertion of the housing assembly 1 into the fixed end of the push-pull rear shell 6 .

[0024] As an embodiment of the present invention, please refer to Figure 1 and Figure 2 The push-pull end of the push-pull rear shell 6 is provided with an anti-slip structure.

[0025] When the operator needs to pull the shell component 1, the anti-slip structure on the surface of the push-pull rear shell 6 can increase the friction between the push-pull end surface of the push-pull rear shell 6 and the operator's palm, so that the operator can complete the pulling process of the shell component 1 more quickly and accurately, avoiding delays in the operation process due to hand slippage and the like.

[0026] In this embodiment, the anti-skid structure may be in the form of anti-skid grooves or anti-skid convex grooves, or an anti-skid pad may be provided on the push-pull end of the push-pull rear housing 6 .

[0027] As an embodiment of the present invention, please refer to Figure 2 A spring 3 is sleeved on the bare optical fiber 4 , and the spring 3 is arranged inside the push-pull rear shell 6 . One end of the spring 3 is connected to the ferrule 2 , and the other end is connected to the stopper 5 .

[0028] The spring 3 is provided to protect and fix the bare optical fiber 4. The ferrule 2 is connected to the spring 3 to maintain the structural stability of the spring 3 and the bare optical fiber 4. The spring 3 is provided in the push-pull rear shell 6, which is equivalent to the push-pull rear shell 6 protecting the spring 3, the ferrule 2 and the bare optical fiber 4, thereby ensuring that the three components will not be affected by the outside world during operation and ensuring the overall structural stability of the looper.

[0029] The working principle of the utility model is as follows: plug the ferrule 2 with the bare optical fiber 4, insert the ferrule 2 into the shell assembly 1, place the bare optical fiber 4 and the stopper 5 inside the push-pull rear shell 6, abut the fixed end of the push-pull rear shell 6 with the rear end of the shell assembly 1, press the push-pull rear shell 6, so that the shell assembly 1 is inserted into the fixed end of the push-pull rear shell 6. During this process, the protrusion 11 and the limit block 12 are inserted into the fixed end of the push-pull rear shell 6. Since the fixed end of the push-pull rear shell 6 is provided with a groove 61, the fixed end of the push-pull rear shell 6 is deformed under the action of the extrusion force, and opens to the upper and lower sides, and continues to Press the push-pull rear shell 6. When the shell assembly 1 is inserted to the specified depth, the fixed end of the push-pull rear shell 6 restores its original shape, the protrusion 11 abuts against the front end of the limit groove 62, and the limit block 12 abuts against the rear end of the limit groove 62 to fix the shell assembly 1, thereby connecting the push-pull rear shell 6 and the shell assembly 1 together. Since the push-pull rear shell 6 has a certain length, when the looper needs to be plugged in and out, the operator can avoid putting his hand into a narrow space to pull the shell assembly 1. The plugging and unplugging can be achieved by focusing on the push-pull end of the push-pull rear shell 6, which is convenient and quick, and improves the service life of the looper.
