Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber connection, in particular to an optical fiber connector. Background Art

[0002] Fiber optic connectors are critical precision components used in fiber optic communication systems to achieve repeatable, fast, and low-loss connections between fibers and between fibers and devices such as optical modules, switches, routers, and optical terminals. The primary task of a fiber optic connector is to precisely align the cores of two optical fibers, enabling efficient transmission of optical signals from one fiber to another or to the optical interface of a device.

[0003] Deficiencies of existing technology: The aforementioned fiber optic connector includes a sleeve and two pins for plugging into the sleeve. The two pins are located on either side of the sleeve, each pin being inserted into the end of an optical fiber. Through the sleeve and the two pins, the optical signal from one optical fiber is transmitted to the other optical fiber. When the fiber optic connector is in use, dust, water vapor, and other contaminants in the air can easily migrate from the pins into the sleeve, causing oxidation and corrosion of the optical fiber and the pins, thereby reducing the service life of the optical fiber and the fiber optic connector. This, in turn, requires frequent replacement of the fiber optic connector and optical fibers, increasing equipment and labor costs. Summary of the Invention

[0004] The object of the present invention is to provide an optical fiber connector to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: An optical fiber connector includes a sleeve and a pin. The end of the sleeve is provided with a support portion, a cleaning block slidably arranged in the support portion, and a sealing mechanism for abutting the optical fiber to seal the optical fiber. The cleaning block is used to abut the optical fiber and to scrape off dirt on the pin.

There are several cleaning blocks, and the cleaning blocks are all slidably arranged in the support groove.

[0007] Preferably, a rotating groove is provided at the bottom of the supporting groove, and an elastic plate for connecting to the cleaning block is rotatably provided in the rotating groove. When the elastic plate is in a natural state, it is in a long strip shape, and when the elastic plate is squeezed by the optical fiber, it is in an arc shape. An elastic groove is provided on the side of the elastic plate close to the cleaning block, and a connecting shaft and a connecting block are provided in the elastic groove. The end of the connecting shaft is connected to the side wall of the elastic groove, and the connecting block is sleeved on the connecting shaft and connected to the cleaning block.

[0008] Preferably, a connecting groove is provided on the side wall of the support groove, and a rotating block group and an arc plate are arranged in the connecting groove. The rotating block group includes a plurality of rotating blocks distributed along the circumference of the support groove and fixed to the elastic plate, and the two ends of the arc plate are fixed to the rotating blocks located at both ends of the elastic plate.

[0009] Preferably, there are several elastic plates, connecting shafts, connecting blocks, rotating block groups and arc plates, and the several elastic plates, connecting shafts, connecting blocks, rotating block groups and arc plates are evenly distributed along the circumference of the support groove, and each elastic plate, connecting shaft, connecting block, rotating block group and arc plate corresponds to each other one by one.

[0010] Preferably, each of the cleaning blocks is provided with a magnetic member, and the magnetic poles of each of the magnetic members facing the optical fiber are the same.

[0011] Preferably, a first sealing groove is provided at the bottom of the rotating groove, and a second sealing groove is provided on the side of the support plate close to the sleeve. The sealing mechanism includes a first sealing airbag, a second sealing airbag and a delay part for delaying the deformation of the first sealing airbag. The first sealing airbag is connected to the side wall of the first sealing groove, and the second sealing airbag is located in the second sealing groove and is connected to the first sealing airbag. When the second sealing airbag is inflated and deformed, the second sealing airbag wraps the side wall of the optical fiber in a circular shape.

[0012] Preferably, the delay member includes a spring and an abutment portion slidably arranged in the first sealing groove, the bottom of the spring is used to abut against the side wall of the elastic plate away from the cleaning block, the top of the spring is connected to the abutment portion, and the abutment portion is connected to the top of the first sealing airbag.

[0013] Preferably, the delay element also includes a piston plate slidably arranged in the first sealed airbag, and the piston plate is used to separate the first sealed airbag into two cavities. When a cavity of the first sealed airbag is squeezed, the piston plate moves and squeezes the other cavity, and moves the gas in the other cavity into the second sealed airbag.

[0014] Preferably, each elastic plate is provided with a transverse groove on the side away from the sleeve, and a connecting rod is provided on the side away from the sleeve, one end of the connecting rod extends into the transverse groove and is plugged into the transverse groove, and the other end of the connecting rod extends outside the support part.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This optical fiber connector has a support portion, a cleaning block, and a sealing mechanism provided on the sleeve. When the pin drives the optical fiber into the sleeve, the cleaning block scrapes away dirt such as dust and water vapor on the pin, and the sealing mechanism seals the connection between the pin and the sleeve, making it difficult for dirt such as dust and water vapor to be transmitted into the sleeve. This further reduces the amount of dirt in the sleeve, making it difficult for the dirt to damage and corrode the optical fiber and the pin, thereby protecting the pin and the optical fiber, extending their service life, and reducing the maintenance cost of disassembly and replacement. 2. This optical fiber connector has a first sealing airbag and a second sealing airbag provided on the support plate. When the pin and the optical fiber are transferred to a set position in the sleeve, the pin squeezes the elastic plate, causing the elastic plate to deform from a long strip to an arc shape. The elastic plate squeezes the first sealing airbag, causing the gas in the first sealing airbag to be transferred to the second sealing airbag. The second sealing airbag wraps the connection between the pin and the sleeve in a circular shape, thereby sealing the connection between the pin and the sleeve, making it difficult for dust and water vapor to be transferred into the sleeve and damage or corrode the pin and the optical fiber, thereby further extending the service life of the pin and the optical fiber. 3. This fiber optic connector uses a delay element. When the elastic plate deforms and squeezes the first sealing airbag, the second sealing airbag is not easily deformed immediately. As a result, when the staff moves the pin and optical fiber to the set position, the second sealing airbag slowly deforms through the piston plate and spring until the pin and optical fiber are transferred to the set position and then the pin and optical fiber are sealed.

[0022] See also Figure 1-7 As shown, the present invention provides a technical solution for an optical fiber connector: An optical fiber 13 connector includes a sleeve 11 and a pin 12. There are two pins 12, and the two pins 12 are located on both sides of the sleeve 11. One end of each pin 12 is used to plug into the sleeve 11, and the other end of each pin 12 is used to wrap the end of the optical fiber 13, so that the two optical fibers 13 are connected to the sleeve 11 through the pin 12.

[0023] A support part 2 is installed on both sides of the sleeve 11, and the support part 2 includes a support plate. The side walls of the two support plates are fixedly connected to the two sides of the sleeve 11. A support groove 21 is horizontally opened on each support plate for the pin 12 to pass through. A rotation groove 22 is opened at the bottom of the support groove 21. An elastic plate 32, a connecting shaft 34 and a connecting block 35 are installed in the rotation groove 22. There are several elastic plates 32. Specifically, there are two elastic plates 32, and the two elastic plates 32 are evenly distributed along the circumference of the support groove 21. The side wall of each elastic plate 32 is slidably connected to the side wall of the rotation groove 22. When the elastic plate 32 is in a natural state, it is long and is located in the support groove 21. When the elastic plate 32 is squeezed by the pin 12, it is arc-shaped and partially moves into the rotation groove 22. Each elastic plate 32 has an elastic groove 33 on its side near the optical fiber 13. There are multiple connecting shafts 34, evenly distributed along the length of the elastic groove 33. Each connecting shaft 34 is located within the elastic groove 33 and is integrally formed with the sidewalls of the groove 33. Each connecting shaft 34 is made of the same material as the elastic plate 32. There are multiple connecting blocks 35, evenly distributed along the length of the elastic groove 33. Each connecting block 35 corresponds to each connecting shaft 34 and is sleeved onto and slidably connected to the connecting shaft 34. The sidewalls of each connecting block 35 abut against the sidewalls of the elastic groove 33. A cleaning block 31 is mounted on the side of each connecting block 35 near the pin 12. The sidewalls of the cleaning block 31 abut against the sidewalls of the pin 12 to scrape away dirt from the pin 12. A magnetic part 36 is installed on the side wall of each cleaning block 31, and the magnetism of the side of each magnetic part 36 facing the pin 12 is the same, so that the magnetic parts 36 on the two elastic plates 32 repel each other, so that there is a gap between the two elastic plates 32 in the natural state, which makes it convenient for the staff to insert the pin 12 and the optical fiber 13 along the gap, and then facilitates moving the pin 12 and the optical fiber 13 to the set position in the sleeve 11.

[0024] The support groove 21 is provided with a connecting groove 23 on one side close to the sleeve 11, and a rotating block 41 group and an arc plate 42 are installed in the connecting groove 23. There are several rotating blocks 41 groups and arc plates 42. Specifically, there are two rotating blocks 41 groups and arc plates 42, and the two rotating blocks 41 groups, the two arc plates 42 and the two elastic plates 32 correspond one to one. Each rotating block 41 group includes two rotating blocks 41, and the two rotating blocks 41 are respectively located at the ends of the same side of the elastic plate 32 and are fixedly connected to the elastic plate 32. The horizontally arranged arc plate 42 is arc-shaped, and the two ends of the arc plate 42 are fixedly connected to the two rotating blocks 41 on the same elastic plate 32. The two ends of the elastic plate 32 are fixed by the arc plate 42 and the two rotating blocks 41 on each elastic plate 32, so that the distance between the two ends of the elastic plate 32 is constant, so that the elastic plate 32 is elastically deformed along the radial direction of the support groove 21. In addition, a drive groove 26 is horizontally opened on the side of the support plate away from the sleeve 11. The drive groove 26 is arc-shaped and connected to the rotation groove 22. A transverse groove 37 is horizontally opened on the side of the elastic plate 32 away from the sleeve 11. A connecting rod 6 is detachably connected to the support plate. One end of the connecting rod 6 is used to pass through the drive groove 26 and then be plugged into the transverse groove 37, and the other end of the connecting rod 6 extends outside the support plate.

[0025] When the pin 12 drives the optical fiber 13 to move in the direction close to the sleeve 11, the end of the pin 12 first abuts against the cleaning block 31. At this time, the two elastic plates 32 are squeezed and continue to deform from the natural strip shape when the pin 12 continues to move. Through the arc plate 42 and the two rotating blocks 41, the distance between the two ends of each elastic plate 32 is constant, so that the two elastic plates 32 gradually deform into an arc shape, and part of each elastic plate 32 is deformed from the supporting groove 21 to the rotating groove 22. At this time, when the pin 12 and the optical fiber 13 continue to move, the staff will connect the rod 6 The end portion is plugged into the transverse groove 37 on the elastic plate 32, and the connecting rod 6 is rotated along the rotation axis of the support groove 21, thereby driving the elastic plate 32 to rotate synchronously. The rotation of the elastic plate 32 drives the connecting shaft 34 and the connecting block 35 to rotate synchronously, thereby driving the cleaning block 31 to rotate synchronously, further increasing the contact area between the cleaning block 31 and the pin 12, expanding the cleaning range of the cleaning block 31, and making it difficult for dirt on the pin 12 to be transmitted to the sleeve 11, making it difficult for dirt to accumulate in the sleeve 11 and damage the optical fiber 13 and the optical fiber 13 processor, thereby extending the service life of the optical fiber 13 and the optical fiber 13 processor.

[0026] In order to further improve the sealing between the pin 12 and the sleeve 11, a first sealing groove 24 is opened at the bottom of the rotating groove 22, and a second sealing groove 25 is opened on the side wall of the first sealing groove 24. The first sealing groove 24 is connected to the second sealing groove 25, and an L shape is formed between the first sealing groove 24 and the second sealing groove 25. A sealing mechanism 5 is installed in the first sealing groove 24 and the second sealing groove 25. The sealing mechanism 5 includes a delay piece 53, a first sealing airbag 51 and a second sealing airbag 52. The delay piece 53 includes an abutting portion 532, a spring 531 and a piston plate 533. The abutting portion 532 is located in the first sealing groove 24 and is slidably connected to the side wall of the first sealing groove 24. The bottom of the spring 531 abuts the elastic plate 32, and the top of the spring 531 is fixedly connected to the bottom of the abutting portion 532. The first sealing airbag 51 is located in the first sealing groove 24 and is located on the side of the abutting portion 532 away from the pin 12. The top of the first sealing airbag 51 is fixedly connected to the bottom of the first sealing groove 24. The bottom of the first sealing airbag 51 is used to abut against the top of the abutting portion 532. The piston plate 533 is slidably arranged in the first sealing airbag 51, and the moving direction of the piston plate 533 is consistent with the moving direction of the pin 12 and the optical fiber 13. The second sealing airbag 52 is located on the side of the first sealing airbag 51 close to the sleeve 11 and in the second sealing groove 25. Among the six surfaces of the second sealing airbag 52, except for the surface in contact with the pin 12, the other surfaces are in contact with the side wall of the second sealing groove 25.

[0027] When the first sealing airbag 51 is squeezed by the elastic plate 32, part of the gas in the first sealing airbag 51 gradually moves into the second sealing airbag 52 under the drive of the piston. At this time, the second sealing airbag 52 gradually expands, so that the two second sealing airbags 52 wrap the connection between the pin 12 and the sleeve 11 in a circular shape, thereby improving the airtightness of the connection between the pin 12 and the sleeve 11, making it difficult for dirt such as dust and water to move into the sleeve 11 and corrode and damage the sleeve 11, further protecting the sleeve 11 and extending the service life of the optical fiber 13 and the pin 12. At the same time, through the delay piece 53, when the pin 12 and the optical fiber 13 come into contact with the cleaning block 31 on the elastic plate 32, the second sealing airbag 52 is not easily deformed immediately. After the set time, the two second sealing airbags 52 wrap the pin 12 in a circular shape.

[0028] The working principle of the present invention is as follows: When using an optical fiber 13 connector of this embodiment, the staff moves the pin 12 and the optical fiber 13 in the direction close to the sleeve 11 until the pin 12 contacts the cleaning block 31 on the elastic plate 32. When the pin 12 and the optical fiber 13 continue to move, the pin 12 lifts the cleaning block 31, thereby driving the elastic plate 32 to deform synchronously, so that the elastic plate 32 is deformed from a long strip into an arc shape, and the middle part of the elastic plate 32 moves from the supporting groove 21 to the rotating groove 22. Since the cleaning block 31 abuts the side wall of the pin 12, when the pin 12 moves in the direction close to the sleeve 11, the cleaning block 31 is used to clean dirt on the pin 12. When the elastic plate 32 is deformed to a set angle, the staff adjusts the connecting rod 6 so that the connecting rod 6 is plugged into the transverse groove 37 on the elastic plate 32. The staff rotates the connecting rod 6, thereby driving the elastic plate 32, the connecting shaft 34, the connecting block 35 and the cleaning block 31 to rotate synchronously, thereby expanding the contact area between the cleaning block 31 and the pin 12, further expanding the cleaning range of the cleaning block 31, further reducing the dirt on the pin 12, reducing the damage caused by the dirt to the pin 12 and the optical fiber 13 in the sleeve 11, and extending the service life of the sleeve 11 and the pin 12.

[0029] In addition, when the elastic plate 32 is deformed from a long strip into an arc shape, the abutment plate moves in a direction away from the elastic plate 32 through the elastic potential energy of the spring 531, thereby squeezing the first sealing airbag 51, so that part of the gas in the first sealing airbag 51 is transmitted to the second sealing airbag 52, thereby causing the second sealing airbag 52 to deform, and causing the two second sealing airbags 52 to wrap the connecting groove 23 of the pin 12 and the sleeve 11 in a circular shape. At the same time, due to the elastic potential energy of the elasticity and the delay effect of the piston plate 533, there is a time interval between the deformation of the elastic plate 32 and the deformation of the first sealing airbag 51 and the second sealing airbag 52, so that the first sealing airbag 51 and the second sealing airbag 52 are deformed to the set degree only after the staff transfers the pin 12 and the optical fiber 13 to the set position in the sleeve 11, so that the two second sealing airbags 52 are annular and delay the sealing of the pin 12, so that after the pin 12 and the optical fiber 13 are transferred to the set position, the connecting groove 23 between the pin 12 and the sleeve 11 is sealed, so that water and other dirt are not easily transferred to the connecting groove 23 between the pin 12 and the sleeve 11, further making it difficult for dirt to damage the pin 12 and the sleeve 11, further protecting the sleeve 11 and the pin 12, extending the service life of the sleeve 11 and the pin 12, and at the same time, there is no need to frequently disassemble and replace the optical fiber connector, reducing equipment cost and labor cost.
