Description

Technical Field

[0001] The invention relates to the technical field of optical splitters, in particular to a high-performance optical splitter. Background Art

[0002] With the development of science and technology, fiber optic communication technology has been popularized in thousands of households. Optical splitters are important passive components in fiber optic communication. Optical splitters are fiber optic junction devices with multiple input ports and multiple output ports. During the use of optical splitters, in order to ensure the stability of fiber optic link communication, it is necessary to keep the optical splitters working at high performance to avoid signal transmission interruption or data loss caused by external influences.

[0003] During the use of the existing optical splitter, an external optical fiber line needs to be inserted into the interface of the optical splitter through a plug, and the signal is transmitted and switched inside the optical splitter. During the connection process, since the external line is exposed to the outside, it is easily affected by uncertain factors in the external environment and dragged and pulled, which in turn affects the tight connectivity of the connection between the optical fiber line and the optical splitter. In severe cases, it may cause the connector to fall off, interrupt the optical fiber communication, and affect the performance of the optical splitter. In view of this, we designed a high-performance optical splitter. Summary of the invention

At the same time, the spiral spring 64 is sleeved on the outer side of the rotating rod 62. Specifically, in the initial state, the spiral spring 64 is in a static state. After the winding drum 63 rotates, the spiral spring 64 is stretched. When the winding drum 63 is no longer subjected to external force and rotates, it has the ability to restore the illustrated state under the elastic force of the spiral spring 64.

[0037] In an embodiment of the present invention, a handle is rotatably installed on the left outer wall of the turntable 91 to facilitate the staff to rotate the turntable 91. At the same time, a through cavity corresponding to the anti-drag frame 5 is opened inside the reel-up frame 8 to ensure the normal routing of the optical fiber line. Further, the interior of the reel-up drum 95 is hollow, and the diameter of the cavity inside the reel-up drum 95 is larger than the outer diameter of the rotating shaft 92, so that when the reel-up drum 95 remains relatively still, the rotation of the rotating shaft 92 will not affect the reel-up drum 95. Further, the rotating shaft 92 passes through a first gear 94, and the rotating shaft 92 is rotatably connected to the first gear 94. In addition, the rotating shaft 92 passes through a control disk 96, and the control disk 96 is rotatably connected to the rotating shaft 92. Specifically, a reset spring 99 is sleeved on the outer side of the plug rod 97. Further, a limit hole equal in size to the bottom end of the plug rod 97 is opened on the arc-shaped outer wall of the rotating shaft 92.

[0038] In addition, in order to prevent the optical fiber line from being excessively entangled when being wound on the winding drum 95, thereby causing damage to the optical fiber itself, an anti-winding component 10 is arranged inside the winding frame 8, and the anti-winding component 10 includes a reciprocating screw rod 101, the reciprocating screw rod 101 is rotatably mounted on the inner wall of the winding frame 8, the reciprocating screw rod 101 passes through a second gear 102, and the second gear 102 is fixedly connected to the reciprocating screw rod 101, the outer wall of the reciprocating screw rod 101 is threadedly connected with a threaded transmission plate 103, the top inner wall of the threaded transmission plate 103 is slidably connected with a connecting slide plate 104, the upper surface of the connecting slide plate 104 is fixedly connected with a second telescopic rod 105, the top end of the second telescopic rod 105 is fixedly connected to the top inner wall of the threaded transmission plate 103, the upper surface of the connecting slide plate 104 is fixedly connected with the bottom end of a protective spring 106, the top end of the protective spring 106 is fixedly connected to the top inner wall of the threaded transmission plate 103, and the upper surface of the connecting slide plate 104 is fixedly connected with a limiting ring 107.

Furthermore, two baffles are provided on the reciprocating screw rod 101, and the two baffles are just arranged directly below the winding drum 95 to limit the moving position of the threaded transmission plate 103. In addition, the lower surface of the threaded transmission plate 103 is slidably connected to the bottom surface of the through cavity opened inside the winding frame 8 to limit the movement direction of the threaded transmission plate 103, so that under the rotation of the reciprocating screw rod 101, the threaded transmission plate 103 can only move in the horizontal direction along the bottom surface of the through cavity opened inside the winding frame 8. Further, the outer walls on the left and right sides of the connecting slide 104 are slidably connected to the inner wall of the threaded transmission plate 103. At the same time, the second telescopic rod 105 is hollow, and the diameter of the internal cavity of the second telescopic rod 105 is larger than the outer diameter of the connecting part of the limiting ring 107 and the connecting slide 104 to ensure that the limiting ring 107 will not interfere with the second telescopic rod 105 when in use, thereby ensuring the stability of the device when in use.

[0040] In the present invention, when in use, the external optical fiber line first passes through the limit ring 107, passes through the through cavity opened in the winding frame 8, and then passes through the through cavity opened in the anti-drag frame 5, and then is wound around the winding drum 63 for a certain number of turns, and finally the optical fiber plug is inserted into the interface 2 fixedly installed on the right outer wall of the optical splitter body 1, so as to achieve the connection of the optical fiber line. In order to ensure the stability of the connection of the optical fiber line and thus ensure the efficient operation of the optical splitter body 1, an anti-drag component 6 is provided, so that the externally erected optical fiber line can be pulled accidentally by people walking or other objects moving. In cooperation with the spiral spring 64 and the protection spring 67, a certain protection effect is played for the connection between the optical fiber line and the interface 2, so as to prevent the optical fiber plug on the interface 2 from being directly pulled and falling off or damaged, thereby affecting the normal signal transmission effect of the subsequent optical fiber line, thereby ensuring the efficient operation of the optical splitter body 1. Furthermore, in order to prevent the optical fiber line from being too long when it is installed, thereby affecting the space inside the installation device of the optical splitter body 1, a winding assembly 9 is provided, and the staff rotates the turntable 91 and cooperates with the rotating shaft 92 to make the winding drum 95 rotate continuously. Then, the external optical fiber line is rolled up to prevent the optical fiber line from being scattered outside and affecting the space inside the device installed on the optical splitter body 1, thereby ensuring the safety of the device. Furthermore, by providing an insertion rod 97, when the staff is rolling up the optical fiber on different interfaces 2, they can pull the pull ring 98 upward to separate the control disk 96 from the rotating shaft 92. The staff can then perform a separate rolling operation according to the optical fiber line that needs to be rolled up without affecting the optical fiber lines connected to other interfaces 2. Further, In order to avoid the disorderly entanglement of the optical fiber line on the winding drum 95 when winding, which will affect the subsequent extraction and use of the optical fiber line, an anti-entanglement component 10 is provided.
