[0002] Optical fiber is a fiber made of glass or plastic, mainly used for light transmission. Fiber optic communication technology is an important part of modern communications. It uses light waves as information carriers and transmits information through optical fibers. There are many optical fiber connectors in a residential network, and two optical fibers are connected through optical fiber connectors.

[0003] For example, in an improved optical fiber connector protection device in an optical resident network with publication number CN108681000A, a slide plate hole is provided at the lower part of the left clamping plate, the slide plate passes through the slide plate hole and is slidably connected to the left clamping plate, the right clamping plate is fixedly connected to the slide plate, and a spring is fixedly connected on both sides of the upper end of the right clamping plate to limit the optical fiber connector through the left and right clamping plates.

[0004] The above-mentioned optical fiber connector protection device clamps and fixes the optical fiber connector through left and right clamps. The left and right clamps are connected by a spring. The spring has a certain elasticity. When the optical fiber is pulled by a large external force, the clamping force of the left and right clamps is not enough to support the external force. The two docked optical fiber connectors are still easily pulled apart, disconnected or falling off. Utility Model Content

[0005] The purpose of the present utility model is to provide an optical fiber connector protection device to solve the problem in the current market raised in the above background technology that when the optical fiber is pulled by a large external force, the clamping force of the left and right clamps is insufficient to support the external force, and the two butt-jointed optical fiber connectors are still easily pulled apart, disconnected or falling off.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an optical fiber connector protection device, comprising a protective cover and fasteners, which are installed around the protective cover, wherein multiple sets of fixing components are installed inside the protective cover, and connecting rods are sliding inside the multiple sets of fixing components. A limiting ring is installed at the end of the connecting rod, and the limiting ring is sleeved on the optical fiber body connector to protect the optical fiber body connector and prevent the optical fiber body from detaching during the pulling process.

[0007] Preferably, each set of fixing components consists of two mutually symmetrical fixing plates, and both ends of the fixing plates are inclined toward one side of the optical fiber body.

[0008] Preferably, the interior of the protective cover is fitted with multiple groups of pushing components, each group of pushing components consists of two symmetrical pushing plates, both ends of the pushing plates are also tilted, and the tilt angles of the two ends of the pushing plates are the same as the tilt angles of the two ends of the fixed plate.

[0009] Preferably, both ends of the fixing plate are provided with horizontal sliding grooves, and a limiting rod parallel to the fixing plate is installed inside the sliding groove, and the limiting rod is inserted into the interior of the connecting rod.

[0010] Preferably, a threaded rod is rotatably connected to the interior of the protective cover, and the end of the threaded rod protrudes from the outer end of the protective cover.

[0011] Preferably, the threaded rod is threadedly connected to the push plate, and the thread directions of the two push plates in each push assembly are opposite to those of the threaded rod at the threaded connection positions, and the push plates slide with the protective cover through the threaded rod.

[0012] Preferably, the diameter of the limiting ring is smaller than the diameter of the optical fiber body connector, and the optical fiber body is located in the middle position of each set of fixing components.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model is provided with a fixing plate, a limiting ring, a limiting rod and a sliding groove. The two ends of the fixing plate are inclined toward one side of the limiting ring. The limiting ring is wrapped around the optical fiber body connector position. The size of the optical fiber body connector is generally larger than the size of the optical fiber body line. Due to the structure of the fixing plate, the optical fiber body will not move to the two end positions when it is pulled. Therefore, the connection position of the two optical fiber body connectors will not be pulled apart by external force, preventing the two connected optical fiber body lines from detaching, protecting the optical fiber body connectors, and at the same time, multiple optical fiber connectors can be stored together in an orderly manner without being tangled together.

[0015] 2. The present invention is provided with a push plate and a threaded rod. The rotation of the threaded rod causes multiple push plates to move simultaneously. The two push plates of each pushing assembly move in opposite directions. During the movement of the push plate to the middle position, the connecting rod is pushed, and one end of the connecting rod is limited, so that the connecting rod and the limiting ring remain stable, preventing the limiting ring from sliding unstably on the optical fiber body and then failing to protect the optical fiber body connector position when the optical fiber body is pulled.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-4 , the utility model provides the following technical solutions:

[0023] A fiber optic connector protection device includes a protective cover 1 and a fastener 2, which are installed around the protective cover 1. Multiple groups of fixing components are installed inside the protective cover 1. Connecting rods 9 are slid inside the multiple groups of fixing components. A limiting ring 4 is installed at the end of the connecting rod 9. The limiting ring 4 is sleeved on the connector of the optical fiber body 3 to protect the connector of the optical fiber body 3 and prevent the optical fiber body 3 from detaching during the pulling process. The diameter of the limiting ring 4 is smaller than the diameter of the connector of the optical fiber body 3. The optical fiber body 3 is located in the middle position of each group of fixing components.

[0024] Place the optical fiber body 3 in the middle position of the limiting ring 4, push the connecting rod 9 toward the connector position of the optical fiber body 3, and the movement of the connecting rod 9 drives the limiting ring 4 to move synchronously. During the movement of the limiting ring 4, the distance between the limiting rings 4 on both sides becomes larger. When the limiting rings 4 on both sides completely wrap the connector of the optical fiber body 3, they will no longer move.

[0025] Each set of fixing components consists of two symmetrical fixing plates 5, both ends of the fixing plates 5 are inclined toward one side of the optical fiber body 3, and multiple sets of pushing components are fitted inside the protective cover 1, and each set of pushing components consists of two symmetrical push plates 6, both ends of the push plates 6 are also inclined, and the inclination angles of both ends of the push plates 6 are the same as the inclination angles of both ends of the fixing plates 5. Both ends of the fixing plates 5 are provided with horizontal slide grooves 7, and a limiting rod 10 parallel to the fixing plates 5 is installed inside the slide groove 7, and the limiting rod 10 is inserted into the interior of the connecting rod 9.

[0026] By setting the limiting rod 10, the moving direction of the connecting rod 9 is the same as the tilt of the fixing plate 5, thereby changing the distance between the limiting ring 4 and the connecting rod 9 and the optical fiber body 3, which can limit the position of the optical fiber body 3 connector and at the same time make multiple optical fiber body 3 connectors stored together in an orderly manner without being tangled together.

[0027] The protective cover 1 is internally rotatably connected to a threaded rod 8, the end of the threaded rod 8 protrudes from the outer end of the protective cover 1, and the threaded rod 8 is threadedly connected to the push plate 6. The thread directions of the two push plates 6 and the threaded connection positions of the threaded rod 8 of each pushing assembly are opposite, and the push plate 6 slides with the protective cover 1 through the threaded rod 8.

[0028] Turn the threaded rod 8 by hand, and the threaded rod 8 rotates to move the push plates 6 on both sides of each push assembly to the middle position, and the push plates 6 move to the side close to the optical fiber body 3 until the threaded rod 8 can no longer be rotated. At this time, the push plates 6 move to fit the end of the connecting rod 9, limiting the connecting rod 9, so that the limiting ring 4 wraps the connector of the optical fiber body 3, limiting the connector of the optical fiber body 3.
