Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber connection, in particular to a snap-on rotary connector. Background Art

[0002] Optical fiber, full name optical fiber, is a bendable pure glass fiber made of glass or plastic. It is also a light transmission tool that uses the principle of total internal reflection to transmit light in these fibers. The world's first optical fiber was manufactured by the father of optical fiber, Charles Kao. The inner core of most optical fibers is glass fiber, and the core of network cables is mostly made of copper core material. In long-distance transmission, the transmission distance of single-mode optical fiber can reach 10-20km, and multi-mode optical fiber can also transmit distances of 2km-3km, which is much higher than the transmission distance of network cables. Network cables are mainly used for connections between devices, and optical fibers are mainly used for broadband communications.

[0003] A rotary connector is required for docking optical fibers. However, most existing rotary connector connection methods involve a connector at one end being sleeved onto a plug at the other end to connect through friction. This causes the connected rotary connector to easily fall off after being pulled, reducing the practicality of the rotary connector.

[0004] Therefore, it is necessary to improve the rotary connector to prevent the rotary connector from falling off when being dragged. Utility Model Content

[0005] In order to solve the problems raised in the above-mentioned background technology, the purpose of the present invention is to provide a snap-on rotary connector, which has the advantage of good anti-falling effect, and solves the problem that most of the connection methods of existing rotary connectors are that the connector at one end is sleeved on the connector at the other end and connected by friction, which causes the connected optical fiber to easily fall off after being pulled, reducing the practicality of the rotary connector.

[0023] Rotating plug 1, the surface of rotating plug 1 is sleeved with rotating joint 2, the surface of rotating plug 1 is in contact with the inner wall of rotating joint 2, the left side of pressing plate 3 is fixedly connected with the left side of rotating plug 1, the left side of pressing plate 3 is in contact with the right side of rotating joint 2, the surface of rotating joint 2 is provided with sliding slot 4, rotating ring 5 is slidably connected in the inside of sliding slot 4, the top and bottom of rotating ring 5 are fixedly connected with limit box 6, push plate 7 is slidably connected in the inside of limit box 6, the four corners of the bottom of push plate 7 are fixedly connected with spring 8, the bottom of spring 8 is fixedly connected with the bottom of the inner wall of limit box 6, the right side of push plate 7 is fixedly connected with connecting plate 9, connecting plate 9 is fixedly connected with clamping plate 10 on the right side and penetrates to the right side of pressing plate 3, the left side of clamping plate 10 is in contact with the right side of pressing plate 3, the outside of push plate 7 is fixedly connected with pressing rod 11, the outside of pressing rod 11 penetrates to the top of limit box 6 and is slidably connected with the inner wall of limit box 6.

[0024] Reference Figure 1 , the outside of pressing rod 11 is fixedly connected with pressing pad 12, and pressing pad 12 is used in cooperation with pressing rod 11.

[0025] As a technical optimization scheme of the utility model, by setting pressing pad 12, the user can press down pressing rod 11, and the comfort of the user is improved.

[0026] Reference Figure 3A friction pad 13 is fixedly connected to the left side of the clamping plate 10 , and the left side of the friction pad 13 contacts the right side of the pressing plate 3 .

[0027] As a technical optimization solution of the present invention, by providing the friction pad 13 , the contact between the clamping plate 10 and the pressing plate 3 can be made tighter, thereby increasing the contact area between the clamping plate 10 and the pressing plate 3 .

[0028] refer to Figure 2 The top and bottom of the inner wall of the pressing plate 3 are both provided with openings 14 , the width of the opening 14 is greater than the width of the connecting plate 9 , and the opening 14 is used in conjunction with the connecting plate 9 .

[0029] As a technical optimization solution of the present invention, by setting the opening 14, the connecting plate 9 and the clamping plate 10 can be completely passed through the pressure plate 3 for positioning, preventing the opening 14 from being too small and causing the connecting plate 9 and the clamping plate 10 to be stuck.

[0030] refer to Figure 4 Four limiting rods 15 are vertically fixedly connected to the interior of the limiting box 6 , and the limiting rods 15 pass through the push plate 7 and are slidably connected to the push plate 7 .

[0031] As a technical optimization solution of the present invention, by providing a limiting rod 15, the push plate 7 can be limited, thereby improving the stability of the push plate 7 during movement.

[0032] refer to Figure 2 The surface of the rotary plug 1 is provided with an anti-slip sleeve 16 , which is used in conjunction with the rotary plug 1 .

[0033] As a technical optimization solution of the present invention, the provision of the anti-slip sleeve 16 can facilitate the user in plugging the rotary plug 1 and prevent the user from slipping when plugging the rotary plug 1 .

[0034] The working principle and usage process of the utility model: When in use, first press the pressure rods 11 on both sides inward with the thumb and index finger respectively, the pressure rod 11 drives the push plate 7 to move inward, the push plate 7 drives the connecting plate 9 to move inward, and the connecting plate 9 drives the clamping plate 10 to move inward. After moving to the limit position, the rotating plug 1 is inserted into the interior of the rotary joint 2 with the other hand. After the rotary joint 2 is partially inserted, the rotating ring 5 is rotated, and the rotating ring 5 drives the limit box 6 to rotate so that the limit box 6 is aligned with the opening 14 on the surface of the pressure plate 3. After the alignment is completed, the rotary plug 1 is fully inserted and the pressure rod 11 is released. The push plate 7, the connecting plate 9 and the clamping plate 10 are driven upward by the elastic force of the rebounder 8, so that the clamping plate 10 is clamped on the surface of the pressure plate 3.

[0035] When the cam 11 is released, the push plate 7 and the connecting plate 9 are moved inwards, and the connecting plate 9 drives the clamping plate 10 to move inwards. After the cam 11 is moved to the limit position, the cam 11 is inserted into the inner part of the cam 2 by the other hand. After the cam 2 is partially inserted, the cam 2 is rotated, and the cam 5 drives the limit box 6 to rotate so that the limit box 6 is aligned with the opening 14 on the surface of the pressure plate 3. After the alignment is completed, the cam 11 is fully inserted and the pressure rod 11 is released. The elastic force of the rebounder 8 drives the push plate 7, the connecting plate 9 and the clamping plate 10 to move upwards, so that the clamping plate 10 is clamped on the surface of the pressure plate 3, thereby having the advantage of good anti-falling effect. It solves the problem that most of the connection methods of existing rotary connectors are that the connector at one end is sleeved on the connector at the other end to be connected by friction. This causes the connected optical fiber to easily fall off after being pulled, reducing the practicality of the rotary connector.
