Technical Field

Background

In an optical fiber transmission line, in order to achieve stable connection of different optical fiber segments, two segments of optical fibers are connected by using an optical fiber connector with a certain protection property, so as to achieve permanent or detachable connection. In the process of connection and maintenance of a daily transmission line, the optical fiber connector is required to be flush with the plug-in port of the optical fiber coupler, so that the ceramic ferrule of the optical fiber can be conveniently and stably inserted into the plug-in port of the optical fiber coupler.

In some embodiments, as shown in fig. 2, the optical fiber connection apparatus includes the first shaft 19 and the first gear 20, the first shaft 19 and the first gear 20 are positioned between the third moving plate 29 and the fourth moving plate 30, and the third moving plate 29 and the fourth moving plate 30 are engaged with the first gear 20. Here, the third moving plate 29 is engaged with the first gear 20 in such a manner that: an opening is provided in the third moving plate 29, which extends in the second direction X2. In the second direction X2, a rack is provided on one side of the opening, and the length of the rack is less than or equal to the length of the opening in the second direction X2.

In the above optical fiber connecting device, by disposing the first gear 20 between the third moving plate 29 and the fourth moving plate 30 and engaging the third moving plate 29 and the fourth moving plate 30 with the first gear 20, when the first elastic component 16 drives the first clamping frame 4 to move toward the first connecting plate 12, the first clamping frame 4 can drive the first gear 20 to rotate due to the engagement with the first gear 20, and the third moving plate 29 and the fourth moving plate 30 can be driven to move toward each other during the rotation of the first gear 20, so as to drive the first fixing plate 2511 and the second fixing plate 2521 to move toward each other. The first clamping plate 44, the first fixing plate 2511, and the second fixing plate 2521 cooperate together to fix the first optical fiber connector 5 in the first direction X1 and the second direction X2. The first clamping plate 44, the first fixing plate 2511 and the second fixing plate 2521 can be driven to move simultaneously by the first elastic component 16, so that the structure of the optical fiber connecting device is simplified, and the optical fiber connecting device is convenient to use.

As shown in fig. 2, alternatively, in the case of the optical fiber connection device having the second shaft 23 and the second gear 24, the second shaft 23 and the second gear 24 are located between the fifth moving plate 33 and the sixth moving plate 34, and the fifth moving plate 33 and the sixth moving plate 34 are engaged with the second gear 24. Here, the fifth moving plate 33 is meshed with the second gear 24 in such a manner that: an opening is formed in the fifth moving plate 33, and extends in the second direction X2. In the second direction X2, a rack is provided on one side of the opening, and the length of the rack is less than or equal to the length of the opening in the second direction X2. The rack is adapted to the second gear wheel 24 such that the fifth movement plate 33 can be brought into engagement with the second gear wheel 24 through the opening provided with the rack. So that the second gear 24 can drive the fifth moving plate 33 to move.

The sixth moving plate 34 and the second gear 24 are engaged in the same manner as the fifth moving plate 33 and the second gear 24, for example, and will not be described here. The second gear 24 may also drive the sixth moving plate 34 to move.

In the above optical fiber connecting device, the second gear 24 is disposed between the third moving plate 29 and the fourth moving plate 30, and the third moving plate 29 and the fourth moving plate 30 are respectively engaged with the second gear 24, so that when the second elastic component 18 drives the second clamping frame 6 to move toward the second connecting plate 22, the second clamping frame 6 can drive the second gear 24 to rotate due to the engagement with the second gear 24, and the second gear 24 can drive the third moving plate 29 and the fourth moving plate 30 to move toward each other during the rotation process of the second gear 24, and further drive the third fixing plate 2611 and the fourth fixing plate 2621 to move toward each other. The second clamping plate 62, the third fixing plate 2611, and the fourth fixing plate 2621 cooperate together to fix the second optical fiber connector 7 in the first direction X1 and the second direction X2. The second clamping plate 62, the third fixing plate 2611 and the fourth fixing plate 2621 can be driven to move simultaneously by a second elastic component, so that the structure of the optical fiber connecting device is further simplified, and the optical fiber connecting device is convenient to use.

In some embodiments, as shown in fig. 2, the first holder 251 and the second holder 252 are disposed symmetrically with respect to the first axis 19. Thus, the positions of the first fixing frame 251 and the second fixing frame 252 meshed with the first gear 20 are located on two opposite sides of the first gear 20, so that the stress of the first gear 20 is more uniform, and the first gear 20 is more stable in rotation. This can improve the stability of the entire optical fiber connection device in operation.

Alternatively, the third fixing frame 261 and the fourth fixing frame 262 may be disposed symmetrically with respect to the second shaft 23. Thus, the positions of the third fixing frame 261 and the second fixing frame 252, which are meshed with the second gear 24, are located on two opposite sides of the second gear 24, so that the stress of the second gear 24 is more uniform, and the second gear 24 is more stable in rotation. This can further improve the stability of the overall optical fiber connection device during operation.
