Description

Technical Field

[0001] This invention relates to the field of optical fiber connector protection technology, specifically a dust cap for optical fiber connectors. Background Technology

[0002] Existing fiber optic connection devices require dust caps to be installed on the card slot ferrule to protect it from damage. However, during use, dirt can easily get into the dust cap's holes, which is detrimental to protecting the card slot ferrule and makes it difficult to remove dirt from the dust cap's holes, thus affecting the performance of the fiber optic connection device.

[0003] The existing application CN201120289779.5 describes a dust cap for fiber optic connectors. It secures the dust cap body to the connector components via the outer diameter of the dust cap itself. The dust cap body features four symmetrically distributed reinforcing ridges and a protective ring, thus tightly fixing the dust cap body to the connector components for dust protection. However, this method of fixing the dust cap body to the connector components is inconvenient, and its fixing effect is only average. Furthermore, it does not restrict the portion of the connector components located inside the dust cap, making it easy for the connector components to collide with and be damaged by the inner side of the dust cap. Additionally, the dust cap is small and easily lost, significantly increasing the protection cost. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a dust cap for fiber optic connectors. The fiber optic connector plug inserted into the dust cap body is fixed by a fixing unit, and then the position of the fiber optic connector plug inside the dust cap body is restricted by a telescopic rod, a limiting ring and a compression spring. The dust cap can be effectively prevented from being lost by means of a collar, a fixing rod, a nylon rope, a hook and a mounting ring, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust cap for an optical fiber connector, comprising a dust cap body and a fixing unit;

[0006] Dust cap body: The dust cap body has a hollow structure. A sealing cover is provided on the left side of the dust cap body. The sealing cover is rotatably connected to the dust cap body through a pivot. The sealing cover and the dust cap body are engaged and snapped together. Two collars are evenly rotatably connected to the outer side of the dust cap body. The two collars are fixedly connected by a number of fixing rods. Nylon ropes are hinged to the outer side of both collars. The two nylon ropes are engaged and hinged together by hooks. An installation ring is fixedly connected to the outer side of the hooks.

[0007] Fixing Units: There are four fixing units in total, evenly distributed on the inner side of the dust cap body. Each fixing unit includes a handle, a threaded rod, and a retaining plate. The retaining plate is an arc-shaped plate. One end of the threaded rod is rotatably connected to the side of the retaining plate, and the other end of the threaded rod is threadedly connected to the inner side of the dust cap body and extends to the outer side of the dust cap body. The end of the threaded rod extending to the outer side of the dust cap body is fixedly connected to the handle. By fixing the mounting ring to the outer side of the fiber optic connector, and then fitting the dust cap body onto the fiber optic connector, the four handles are rotated simultaneously, causing the threaded rod to rotate. This causes the threaded rod to rotate and advance the retaining plate while being threaded on the inner side of the dust cap body, thus bringing the retaining plate into contact with the fiber optic connector and fixing it in place. Finally, by pulling the sealing cap, the sealing cap engages with the dust cap body, sealing the right side of the dust cap body and preventing external dust from interfering with the fiber optic connector.

[0008] Furthermore, it also includes a sleeve, which is located on the right side of the dust cap body. The sleeve has a hollow structure and can be used to organize the connectors that need to be dustproofed, thus preventing the connectors from becoming too messy and unable to be fixed.

[0009] Furthermore, it also includes a sealing block, which is located on the inner side of the sealing cover. The diameter of the sealing block corresponds to the diameter of the inner side of the dust cap body. The sealing block makes the sealing cover and the dust cap body fit together to form a tighter seal.

[0010] Furthermore, it also includes protective strips, which are strip-shaped fixing blocks. The protective strips are evenly distributed on the outer side of the dust cap body. The protective strips can prevent poor installation results caused by a slippery installation environment when the dust cap body is installed.

[0011] Furthermore, it also includes a limiting plate and telescopic rods. The limiting plate is an annular plate, and there are twelve telescopic rods in total. The twelve telescopic rods are evenly distributed on the inner side of the dust cap body. The fixed ends of the telescopic rods are all fixedly connected to the inner side of the dust cap body, and the telescopic ends of the telescopic rods are all fixedly connected to the outer side of the limiting plate. The limiting plate and telescopic rods can restrict the position of the fiber optic connector, thereby preventing the fiber optic connector from directly contacting the inner side of the dust cap body due to shaking inside the dust cap body.

[0012] Furthermore, it also includes compression springs, a total of twelve compression springs, which are respectively sleeved on the outer side of the twelve telescopic rods, and the compression springs can provide buffer protection for the telescopic rods.

[0013] Furthermore, it also includes a handle, which is located on the outer side of the sealing cover, making it easier to close the sealing cover.

[0014] Furthermore, it also includes a telescopic strap, which is a ring-shaped elastic strap. The telescopic strap is located inside the dust cap body. One end of the telescopic strap is fixedly connected to the inner side of the dust cap body, and the other end of the telescopic strap is fixedly connected to the side of the clamping plate. The telescopic strap can seal the connection between the dust cap body and the fiber optic connector, thereby preventing external dust from entering the interior of the dust cap body through the connection.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The dust cap for fiber optic connectors has the following advantages: The dust cap for fiber optic connectors fixes the fiber optic connector insert into the dust cap body through a fixing unit, and then restricts the position of the fiber optic connector inside the dust cap body through a telescopic rod, a limiting ring, and a compression spring, thereby avoiding direct contact between the fiber optic connector and the inner cavity side of the dust cap body, thus protecting the fiber optic connector. The collar, fixing rod, nylon rope, hook, and mounting ring can effectively prevent the dust cap from being lost, thus avoiding loss due to the small size of the dust cap body, thereby greatly saving protection costs.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-3The present invention provides a technical solution: a dust cap for an optical fiber connector, comprising a dust cap body 1 and a fixing unit 2;

[0022] Dust cap body 1: The dust cap body 1 has a hollow structure. A sealing cover 8 is provided on the left side of the dust cap body 1. The sealing cover 8 is rotatably connected to the dust cap body 1 through a rotating shaft 6. The sealing cover 8 and the dust cap body 1 are engaged and snapped together. Two collars 9 are evenly rotatably connected to the outer side of the dust cap body 1. The two collars 9 are fixedly connected to each other by a number of fixing rods 10. Nylon ropes 11 are hinged to the outer side of the two collars 9. The two nylon ropes 11 are engaged and hinged together by hooks 12. An installation ring 13 is fixedly connected to the outer side of the hooks 12.

[0023] Fixing Unit 2: There are four fixing units 2 in total, evenly distributed on the inner side of the dust cap body 1. Each fixing unit 2 includes a handle 21, a threaded rod 22, and a retaining plate 23. The retaining plate 23 is an arc-shaped plate. One end of the threaded rod 22 is rotatably connected to the side of the retaining plate 23, and the other end of the threaded rod 22 is threadedly connected to the inner side of the dust cap body 1 and extends to the outer side of the dust cap body 1. The handle 21 is fixedly connected to the end of the threaded rod 22 extending to the outer side of the dust cap body 1. By fixing the mounting ring 13 onto the outer side of the fiber optic connector, the dust cap body 1 is then... The fiber optic connector is fitted with a socket, and then by simultaneously rotating four handles 21, the handles 21 drive the threaded rods 22 fixedly connected to their sides to rotate. This causes the threaded rods 22 to rotate and advance the clamping plate 23 while engaging with the inner cavity of the dust cap body 1. This allows the clamping plate 23 to contact the fiber optic connector and fix it in place. Then, by pulling the sealing cover 8, the sealing cover 8 engages with the dust cap body 1, thus sealing the right side of the dust cap body 1 and preventing external dust from interfering with the fiber optic connector.

[0024] It also includes a sleeve 3, which is located on the right side of the dust cap body 1. The sleeve 3 has a hollow structure. The sleeve 3 can be used to organize the connectors that need to be dustproofed, so as to avoid the connectors from being too messy and unable to be fixed.

[0025] It also includes a sealing block 7, which is located on the inner side of the sealing cover 8. The diameter of the sealing block 7 corresponds to the diameter of the inner side of the dust cap body 1. The sealing block 7 makes the sealing cover 8 and the dust cap body 1 fit together to form a tighter seal.

[0026] It also includes a protective strip 5, which is a strip-shaped fixing block. The protective strip 5 is evenly distributed on the outer side of the dust cap body 1. The protective strip 5 can prevent poor installation results due to the slippery installation environment when the dust cap body is installed.

[0027] The system also includes a limiting plate 4 and telescopic rods 16. The limiting plate 4 is an annular plate. There are twelve telescopic rods 16 in total, which are evenly distributed on the inner side of the dust cap body 1. The fixed ends of the telescopic rods 16 are fixedly connected to the inner side of the dust cap body 1, and the telescopic ends of the telescopic rods 16 are fixedly connected to the outer side of the limiting plate 4. The limiting plate 4 and the telescopic rods 16 can restrict the position of the fiber optic connector, thereby preventing the fiber optic connector from directly contacting the inner side of the dust cap body due to shaking. The system also includes twelve compression springs 15, which are respectively sleeved on the outer side of the twelve telescopic rods 16. The compression springs 15 can provide buffer protection for the telescopic rods 16.

[0028] It also includes a handle 14, which is located on the outer side of the sealing cover 8. The handle 14 makes it easier to close the sealing cover 8.

[0029] The device also includes a telescopic belt 17, which is an annular elastic belt. The telescopic belt 17 is located inside the dust cap body 1. One end of the telescopic belt 17 is fixedly connected to the inner side of the dust cap body 1, and the other end of the telescopic belt 17 is fixedly connected to the side of the clamping plate 23. The telescopic belt 17 can seal the connection between the dust cap body and the fiber optic connector, thereby preventing external dust from entering the interior of the dust cap body 1 through the connection.

[0030] In use: The sleeve 3 is used to clean the connector body where dust protection is required. The mounting ring 13 is fixedly fitted onto the outer side of the fiber optic connector. Then, the dust cap body 1 is fitted onto the fiber optic connector connector. Simultaneously rotating the four handles 21 causes the threaded rods 22 fixedly connected to their sides to rotate. This causes the threaded rods 22 to rotate and advance the clamping plate 23 while engaging with the inner side of the dust cap body 1, thus bringing the clamping plate 23 into contact with the fiber optic connector connector and securing it. The telescopic belt 17 is then used to secure the connector. The connection between the dust cap body 1 and the fiber optic connector can be sealed to prevent external dust from entering the interior of the dust cap body 1 through the connection. The position of the fiber optic connector can be restricted by the limiting plate 4 and the telescopic rod 16 to prevent the fiber optic connector from directly contacting the inner cavity side of the dust cap body 1 due to shaking. Then, by pulling the sealing cover 8 with the handle 14, the sealing cover 8 is engaged with the dust cap body 1, thereby sealing the right side of the dust cap body 1 and preventing external dust from interfering with the fiber optic connector.
