Description

Technical Field

[0001] This application relates to the field of optical cable connection equipment, and more particularly to an optical cable connector. Background Technology

[0002] Optical cables in ducts are generally laid in urban areas and are typically used as optical cables that enter from outdoors into indoor spaces in access networks or user premises networks, as well as building drop cables in structured cabling, especially for indoor or outdoor overhead cabling.

[0003] During the laying of fiber optic cables in ducts, it is often necessary to connect two cable segments to extend the cable length. In practice, a common connection method involves first using heat fusion to melt and connect the corresponding fiber optic connectors in the two cable segments, and then using heat shrink tubing to secure the two segments. Alternatively, fiber optic connectors can be used to achieve the connection.

[0004] Regarding the aforementioned technologies, using thermal fusion to connect two optical cable segments provides a stable connection; however, the process is complex, requiring specialized equipment and personnel, and is time-consuming. Furthermore, the connection process can lead to prolonged exposure of the optical cable connector to air, increasing the likelihood of dust contamination and affecting signal transmission.

[0005] While existing fiber optic connectors can quickly connect two fiber optic segments, their poor sealing leads to unstable connections and allows dust and moisture to enter the cable ends through gaps, contaminating them and affecting signal transmission. Furthermore, because ducted fiber optic cables are used in underground, humid environments, they are even more susceptible to water vapor contamination. Therefore, it is urgent to solve the problem of developing a fiber optic connector that can achieve both rapid connection and a secure seal.

[0006] invention

[0007] In order to provide a simple and quick connection while ensuring a good seal, thereby reducing the impact of dust, moisture and other factors on the optical cable during operation, this application provides an optical cable connector.

[0008] The optical cable connector provided in this application adopts the following technical solution:

[0009] An optical cable connector includes an optical cable mounting base one, an optical cable mounting base two, and a connecting sleeve; the optical cable mounting base one and the optical cable mounting base two have identical structures and are connected to or detached from both ends of the connecting sleeve; the optical cable mounting base one includes a guide assembly and a ceramic sleeve, the guide assembly including a guide post, a support spring, and a guide sleeve; the guide post slides axially along the guide sleeve, one end of the support spring is fixedly connected to the guide post, and the other end is fixedly connected to the guide sleeve; a sealing ring one and a sealing ring two are fixedly provided on the connecting sleeve; the connecting sleeve includes a connecting plate and a sleeve body, the connecting plate being fixedly disposed within the sleeve body; a snap-fit ​​block is provided on the sleeve body, allowing the optical cable to... The cable mounting base has a slot that matches the snap-fit ​​blocks; a support line is connected between the snap-fit ​​blocks; a clamping ring is provided on the sleeve body, and a drive spring and a support line are connected between the clamping rings; a sliding hole is provided on the connecting sleeve, the sliding hole is arranged radially along the connecting sleeve, and a shearing blade is slidably connected in the sliding hole, the shearing blade is used to cut the support line one and the support line two in sequence; a guide hole is provided on the connecting plate, the axis of the guide hole is arranged perpendicular to the axis of the sliding hole, and the guide hole communicates with the sliding hole, the guide assembly slides along the axial direction of the guide hole; a plurality of mating holes are provided on the connecting plate, the mating holes are used to mate the ends of the ceramic conduit connected to the optical fiber.

[0010] By adopting the above technical solution, when using it, the staff will insert the two ends of the optical cable mounting base one and optical cable mounting base two connecting sleeves.

[0011] During the insertion process, firstly, the end of the guide post abuts against the end of the shearing blade, causing the shearing blade to move along the sliding hole towards the support line one. When the ends of the two guide posts abut against each other, the shearing blade moves exactly to the position of support line one and cuts it. At this time, the slot moves exactly below the locking block. After support line one is cut, the locking block falls into the slot, thereby fixing the relative positions between the locking block and optical cable connector one, and between the locking block and optical cable connector two.

[0012] Then, the guide post slides along the axial direction of the guide sleeve towards the support spring; until the ends of the two guide sleeves abut against each other, causing the shearing blade to be pushed towards the second support line and cut the second support line. After the second support line is cut, the clamping rings move towards each other under the drive spring until they abut against the sides opposite to the snap-fit ​​block. This transmits axial force to the first and second optical cable mounting seats through the snap-fit ​​block, making the first and second optical cable mounting seats more securely connected to the connecting sleeve. At this point, the ends of the ceramic sleeves containing the optical fibers abut against each other.

[0013] When connecting the two ends of the optical cable, the operator simply inserts both optical cable mounting brackets (first and second) into the connecting sleeve simultaneously to connect the two cable sections. This simple and quick operation reduces the likelihood of contaminants entering the connector due to prolonged installation. Furthermore, sealing rings one and two form the first and second lines of defense against dust and moisture entering the connector, ensuring a tight seal and reducing the chance of dust contaminating the fiber end face. This, in turn, minimizes the impact of dust and moisture on the optical cable during operation.

[0014] Optionally, a telescopic head is slidably connected to the end of the guide post, and the telescopic head is configured as a cone shape.

[0015] By adopting the above technical solution, the guide column can drive the shear blade to move, making the movement of the shear blade in the direction of the support line smoother.

[0016] Optionally, the end of the guide sleeve is slidably connected to a telescopic head two, which is configured as a frustum shape.

[0017] By adopting the above technical solution, the guide sleeve can drive the shearing blade to move, making the movement of the shearing blade from support line one to support line two smoother.

[0018] Optionally, a magnet is fixed to the end of the guide sleeve.

[0019] By adopting the above technical solution, the setting of magnets can speed up the connection between optical cable mounting base one and optical cable mounting base two, shorten the connection time, and save the operator's strength.

[0020] Optionally, the diameter of the guide sleeve cross-section is larger than the diameter of the guide post cross-section.

[0021] By adopting the above technical solution, when the guide columns are connected, the shearing blade is pushed to the first support line position; when the guide sleeves are connected, the shearing blade is pushed a certain distance again, so that it moves to the second support line position.

[0022] Optionally, a limiting block is fixed on the outer wall of the guide sleeve, and a limiting groove is opened at the position of the guide hole corresponding to the limiting block, the shape of the limiting groove being adapted to the shape of the limiting block.

[0023] By adopting the above technical solution, the relative positions of optical cable mounting base one and optical cable mounting base two on the connecting sleeve are fixed, so that the optical fibers can correspond to each other and avoid incorrect docking.

[0024] Optionally, the end of the shearing blade is provided with a bevel.

[0025] By adopting the above technical solution, the guide assembly can push the two shear blades in opposite directions.

[0026] Optionally, the end of the snap-fit ​​block is provided with a plug-in portion.

[0027] By adopting the above technical solution, the snap-fit ​​block can be inserted into the slot after the support line is cut.

[0028] Optionally, the optical cable mounting base is provided with a handheld end, and the handheld end has anti-slip texture.

[0029] By adopting the above technical solution, the friction between the operator and the handheld device is increased, saving the operator's effort.

Implementation

[0041] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0042] This application discloses an optical cable connector. (Refer to...) Figure 1 An optical cable connector includes an optical cable mounting base 1, an optical cable mounting base 2, and a connecting sleeve 3. The optical cable mounting base 1 and the optical cable mounting base 2 have identical structures and are used to protect the optical cable end and facilitate connection. In this embodiment, only the internal structure of the optical cable mounting base 1 is described as an example. The connecting sleeve 3 connects the optical cable mounting base 1 and the optical cable mounting base 2 and seals the entire structure.

[0043] Reference Figure 2 The optical cable mounting base 1 includes a handheld end 11 and an anti-bend end 12, which are fixedly connected. The outer wall of the handheld end 11 near the anti-bend end 12 has anti-slip textures to increase friction between the operator and the handheld end 11, saving operator effort. An optical cable body 13 is inserted into the optical cable mounting base 1. During installation, the optical cable body 13 is inserted from the anti-bend end 12 into the handheld end 11.

[0044] Reference Figure 1 , Figure 2 The anti-bend end 12 is made of a flexible material, preferably rubber, to allow the optical cable to bend at the connection point of the handheld end 11. A heat-shrink tubing 14 is fixed to the end of the anti-bend end 12 away from the handheld end 11. After the optical cable body 13 is inserted into the optical cable mounting base 1, the heat-shrink tubing 14 is heated to tightly wrap around the outside of the optical cable body 13. This makes the connection between the optical cable body 13 and the optical cable mounting base 1 more stable and reduces dust from entering the optical cable mounting base 1 from the anti-bend end 12, thus preventing contamination of the optical fiber end face.

[0045] Reference Figure 2 , Figure 3 Several ceramic sleeves 15 are fixed to the end of the handheld end 11 away from the anti-bend end 12. The axis of the ceramic sleeves 15 is set parallel to the axis of the optical cable mounting base 1. Each ceramic sleeve 15 contains one optical fiber from the optical cable body 13.

[0046] Reference Figure 3 , Figure 5 as well as Figure 6 A guide component 4 is provided in the middle of the handheld end 11. The guide component 4 guides the insertion of the optical cable mounting base 1 into the end of the connecting sleeve 3, making the insertion process more stable. The guide component 4 includes a guide post 41, a support spring 42, and a guide sleeve 43. The end of the guide sleeve 43 is fixed to the end of the handheld end 11 away from the anti-bend end 12. The axis of the guide sleeve 43 is parallel to the axial direction of the handheld end 11, and the interior of the guide sleeve 43 is hollow. The support spring 42 is located inside the guide sleeve 43. One end of the support spring 42 is fixed to the inner wall of the guide sleeve 43, and the other end of the support spring 42 is fixed to the end of the guide post 41. The axis of the guide post 41 is parallel to the axis of the guide sleeve 43, and it is inserted into the interior of the guide sleeve 43 along the end of the guide post 41 and slides along the axial direction of the guide sleeve 43. The cross-sectional diameter of the guide sleeve 43 is larger than the cross-sectional diameter of the guide post 41.

[0047] Reference Figure 3 A telescopic head 411, conical in shape, is slidably connected to the end of the guide post 41 furthest from the guide sleeve 43. A second telescopic head 421, frustum-shaped, is slidably connected to the end of the guide sleeve 43 closest to the guide post 41. The guide post 41 and the second telescopic head 421 are slidably connected. A magnet 422 is fixedly mounted on the end of the guide sleeve 43 closest to the guide post 41. A limiting block 423, elongated in shape, is fixedly mounted on the outer wall of the guide sleeve 43, with its length parallel to the axis of the guide sleeve 43.

[0048] Reference Figure 4 The connecting sleeve 3 includes a sleeve body 31 and a connecting plate 32. The sleeve body 31 is hollow inside and is cylindrical. The connecting plate 32 is disc shaped and is fixed in the middle of the sleeve body 31. The side wall of the connecting plate 32 is fixed to the inner wall of the sleeve body 31.

[0049] Reference Figure 4A guide hole 321 is provided in the middle of the connecting plate 32. The axis of the guide hole 321 is parallel to the axis of the connecting plate 32 and penetrates through the connecting plate 32. When the operator applies an axial thrust to the optical cable mounting base 1 and the optical cable mounting base 2, and the optical cable mounting base 1 and the optical cable mounting base 2 are installed into the connecting sleeve 3, the telescopic head 411 at the end of the guide post 41 first enters the guide hole 321 and slides along the axis of the guide hole 321. First, the ends of the two telescopic heads 411 abut against each other. Then, under the action of the thrust, the telescopic head 411 slides along the axis of the guide post 41 towards the guide sleeve 43 until the telescopic head 411 is completely slid into the interior of the guide post 41. Then, the guide posts 41 push against each other, causing the ends of the guide posts 41 to slide along the axis of the guide sleeve 43 until the ends of the guide posts 41 are flush with the ends of the telescopic heads 421. Afterwards, the ends of the telescopic head 421 abut against each other and slide along the axial direction of the guide sleeve 43 under the action of thrust until the two magnets 422 attract each other and abut against each other. The setting of the magnets 422 can speed up the connection between the optical cable mounting base 1 and the optical cable mounting base 2.

[0050] The inner wall of the guide hole 321 is provided with a limiting groove that matches the shape of the limiting block 423, which is not shown in the figure. When the guide sleeve 43 slides along the axial direction of the guide hole 321, the limiting block 423 slides along the length direction of the limiting groove, so that the ceramic sleeves 15 on the optical cable mounting base 1 and the optical cable mounting base 2 can correspond one-to-one, and the corresponding optical fiber ends can be connected to each other.

[0051] Several mating holes are provided on the connecting plate 32, which are not shown in the figure. The mating holes on the connecting plate 32 are positioned corresponding to the positions of the ceramic sleeve 15, and their axes are parallel to the axis of the guide hole 321, passing through the connecting plate 32. The ceramic sleeve 15 slides along the axial direction of the mating hole and completes mating within the mating hole.

[0052] Reference Figure 4 The sleeve body 31 has two annular receiving cavities 311, which are concentric with the sleeve body 31 and are located on both sides of the connecting plate 32, and are symmetrically arranged relative to the connecting plate 32. Four mounting rods 5 are fixed inside the receiving cavities 311. The mounting rods 5 are long strips, and their length direction is parallel to the axial direction of the connecting plate 32. One end of the mounting rod 5 is fixed to both sides of the connecting plate 32, and the other end extends away from the connecting plate 32. The two mounting rods 5 located on the same side of the connecting plate 32 are arranged along the same diameter of the connecting plate 32 and are located at both ends of the same diameter.

[0053] Reference Figure 4 , Figure 7 as well as Figure 8A mounting groove 51 is provided on the opposite side of the mounting rod 5 on the same side of the connecting plate 32. A compression spring 52 is fixedly installed in each mounting groove 51. A snap-fit ​​block 53 is inserted into the mounting groove 51. One end of the compression spring 52 abuts against the inner wall of the mounting groove 51, and the other end abuts against the end of the snap-fit ​​block 53. A support wire 54 is fixedly connected between the two snap-fit ​​blocks 53 on the same axis of the connecting plate 32. One end of the support wire 54 is fixedly connected to the side wall of the snap-fit ​​block 53, and the other end passes through the mounting rod 5, the connecting plate 32, and the mounting rod 5 in sequence, and is fixedly connected to the side wall of the snap-fit ​​block 53. Supported by the support wire 54, the snap-fit ​​block 53 presses the compression spring 52 towards the mounting groove 51, compressing the compression spring 52 and fixing the snap-fit ​​block 53 in a fixed relative position to the mounting rod 5.

[0054] Reference Figure 3 , Figure 7 Each handheld end 11 has a slot 55 at the position corresponding to the snap-fit ​​block 53, and the shape of the slot 55 is adapted to the shape of the snap-fit ​​block 53. The end of the snap-fit ​​block 53 away from the mounting groove 51 is provided with a plug part 531 so that after the support line 54 is cut, the snap-fit ​​block 53 can be inserted into the slot 55.

[0055] Reference Figure 4 , Figure 8 Each receiving cavity 311 is provided with an annular clamping ring 6, which is concentrically arranged with the receiving cavity 311 and the two clamping rings 6 are arranged parallel to each other. Two support rods 61 are fixed to the inner wall of the receiving cavity 311 at the position corresponding to each clamping ring 6, and the two support rods 61 are located in the receiving cavity 311 away from the connecting plate 32. The two support rods 61 are arranged along the same diameter on the clamping ring, and the line connecting the two support rods 61 is parallel to the line connecting the two mounting rods 5 located on the same side of the connecting plate 32, and the two mounting rods 5 are arranged parallel to each other.

[0056] Reference Figure 4 , Figure 8 Two drive springs 62 are fixed between the two clamping rings 6. The two drive springs 62 are arranged along the same diameter of the sleeve body 31 and are respectively located at both ends of the diameter. One end of the drive spring 62 is fixed to the side wall of the clamping ring 6, and the other end of the drive spring 62 passes through the sleeve body 31 along the axis of the sleeve body 31 and is fixed to the side wall of the other clamping ring 6. A support wire 63 is fixed on the clamping ring 6 at the position corresponding to each drive spring 62. One end of the support wire 63 is fixed to the side of the clamping ring 6 away from the drive spring 62, and the other end of the support wire 63 passes around two support rods 61 on the same axis and is fixed on the side of the clamping ring 6 away from the drive spring 62.

[0057] Under the action of the second support line 63, the relative positions between the two clamping rings 6 and the sleeve body 31 are fixed, and the drive spring 62 is in an extended state. When the second support line 63 is cut, the two clamping rings 6 move towards each other along the sleeve body 31 under the drive of the drive spring 62 until they abut against both sides of the locking block 53.

[0058] Reference Figure 7 Each clamping ring 6 has a connecting hole 64 at the position corresponding to the mounting rod 5, so as to prevent the clamping ring 6 from being interfered with by the mounting rod 5 when moving towards the connecting block and thus unable to continue moving.

[0059] Reference Figure 4 , Figure 6 A sliding hole 7 is provided radially along the connecting plate 32, and the sliding hole 7 is perpendicular to and connected to the guide hole 321. A shearing blade 71 is slidably connected in the sliding hole 7. Two shearing blades 71 are provided, one corresponding to each support line 54. The ends of the two shearing blades 71 that are close to each other are provided with bevels 711, so that the guide assembly 4 can push the two shearing blades 71 in opposite directions.

[0060] In the initial state, the two shear blades 71 are inserted into the sliding hole 7 and fixed in relative position to the connecting plate 32. When the end of the telescopic head 411 abuts against the inclined side 711, the shear blades 71 begin to move axially along the sliding hole 7. When the telescopic head 411 is completely slid into the guide post 41, the end of the shear blade 71 opposite to the inclined side 711 moves to the position of the support line 54 and cuts the support line 54 during the movement. At this time, the slot 55 slides to the bottom of the locking block 53. The locking block 53, which has lost the support of the support line 54, moves towards the slot 55 under the action of the compression spring 52 until it is inserted into the slot 55, thus fixing the locking block 53 in the slot 55. When the telescopic head 421 slides axially along the guide sleeve 43, it again pushes the shearing blade 71 to move axially along the sliding hole 7. When the two magnets 422 attract each other and abut, the shearing blade 71 moves to the position of the blade support line 63 and cuts the support line 63 during the movement. After that, the drive spring 62 retracts, and under the drive of the drive spring 62, the two clamping rings 6 move towards each other until they abut against the side of the snap-fit ​​block 53. Through the elastic force of the drive spring 62, the snap-fit ​​blocks 53 at both ends of the connecting plate 32 are clamped in opposite directions, and through the snap-fit ​​blocks 53, the optical cable mounting base 1 and the optical cable mounting base 2 are clamped towards the connecting plate 32, making the connection between the optical cable mounting base 1 and the optical cable mounting base 2 more tight.

[0061] Reference Figure 5A sealing ring 8 is fixed at both ends of the connecting sleeve 3. The sealing ring 8 is annular. A groove 81 is provided at the handheld end 11 corresponding to the position of the sealing ring 8. The shape of the groove 81 is adapted to the shape of the sealing ring 8. After the optical cable mounting base 1 and the optical cable mounting base 2 are inserted into both ends of the connecting sleeve 3, the sealing ring 8 is engaged in the groove 81, which serves as the first line of defense against dust, moisture and other contaminants entering the connector.

[0062] Two sealing rings 82 are fixedly provided on the inner wall of the connecting sleeve 3, and each sealing ring 82 is provided for each receiving cavity 311. After the optical cable mounting base 1 and optical cable mounting base 2 are inserted into the two ends of the connecting sleeve 3, the sealing rings 82 are clamped between the handheld end 11 and the sleeve body 31, thus forming a second line of defense against dust, moisture and other contaminants entering the connector.

[0063] The implementation principle of an optical cable connector in this application embodiment is as follows:

[0064] First, in a cleanroom environment, the optical cable body 13 is connected to either optical cable mounting base 1 or optical cable mounting base 2. Specifically, the end of the optical cable body 13 is inserted from the anti-bend end 12 into the handheld end 11. Using existing technology, the optical fiber in the cable is installed in the ceramic sleeve 15, and the relative position of the optical fiber and the ceramic sleeve 15 is fixed. Then, the heat shrink tubing 14 is heated, causing it to shrink and tightly wrap around the outside of the optical cable body 13. This makes the connection between the optical cable body 13 and the optical cable mounting base 1 more stable and reduces dust from entering the optical cable mounting base 1 from the anti-bend end 12, thus preventing contamination of the optical fiber end face.

[0065] The optical cable body 13, which is equipped with optical cable mounting base 1 or optical cable mounting base 2, is transported to the installation site. In order to avoid contamination during transportation, the optical cable mounting base 1, optical cable mounting base 2 and connecting sleeve 3 can be sealed and preserved in accordance with existing technology.

[0066] When connecting the two ends of the optical cable body 13, the operator only needs to insert the optical cable mounting bracket 1 and the optical cable mounting bracket 2 into both ends of the connecting sleeve 3 simultaneously to achieve the connection of the two sections of the optical cable body 13. The connection is quick, which reduces the chance of contaminants entering the connector due to excessive installation time. Furthermore, the sealing ring 8 and the sealing ring 82 form the first and second lines of defense against contaminants such as dust and moisture entering the connector, thereby reducing the chance of dust entering and contaminating the fiber end face.

[0067] When the operator applies axial thrust to the optical cable mounting base 1 and the optical cable mounting base 2, and the optical cable mounting base 1 and the optical cable mounting base 2 are installed into the connecting sleeve 3, the telescopic head 411 at the end of the guide post 41 first enters the guide hole 321 and slides along the axial direction of the guide hole 321.

[0068] First, the ends of the two telescopic heads 411 abut together. Then, under the action of thrust, the telescopic heads 411 slide along the axial direction of the guide post 41 towards the guide sleeve 43 until they are completely inserted into the guide post 41. During this process, when the end of the telescopic head 411 abuts against the inclined side 711, the shearing blade 71 begins to move along the axial direction of the sliding hole 7. When the telescopic head 411 is completely inserted into the guide post 41, the end of the shearing blade 71 opposite to the inclined side 711 moves to the position of the support line 54 and cuts the support line 54 during the movement. At this time, the slot 55 slides to the bottom of the locking block 53. The locking block 53, which has lost the support of the support line 54, moves towards the slot 55 under the action of the compression spring 52 until it is inserted into the slot 55, thus fixing the locking block 53 in the slot 55.

[0069] Then, the guide posts 41 push against each other, causing the ends of the guide posts 41 to slide axially along the guide sleeve 43 until the ends of the guide posts 41 are flush with the ends of the telescopic head 421. Afterwards, the ends of the telescopic heads 421 abut against each other and slide axially along the guide sleeve 43 under the action of thrust until the two magnets 422 attract and abut against each other. The magnets 422 accelerate the connection between the optical cable mounting base 1 and the optical cable mounting base 2. At this time, the ends of the ceramic sleeve 15 containing the optical fiber abut against each other.

[0070] During this process, when the telescopic head 421 slides axially along the guide sleeve 43, it again pushes the shearing blade 71 to move axially along the sliding hole 7; when the two magnets 422 attract each other and abut, the shearing blade 71 moves to the position of the blade support line 63 and cuts the support line 63 during the movement; then, the drive spring 62 retracts, and under the drive of the drive spring 62, the two clamping rings 6 move towards each other until they abut against the side of the snap-fit ​​block 53. Through the elastic force of the drive spring 62, the snap-fit ​​blocks 53 at both ends of the connecting plate 32 are clamped in opposite directions, and through the snap-fit ​​blocks 53, the optical cable mounting base 1 and the optical cable mounting base 2 are clamped towards the connecting plate 32, making the connection between the optical cable mounting base 1 and the optical cable mounting base 2 more tight.

[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
