Description

Technical Field

[0001] The invention relates to the technical field of optical fiber connectors, and in particular to an optical cable fixing and clamping device for an optical fiber active connector. Background Art

[0002] Leather cable is an optical cable covered with a protective sheath. It is soft, light, and easy to install, so it is widely used in small networks such as homes and offices. The flexibility and bending performance of leather cable make it more flexible in the wiring process and can easily cope with various complex wiring environments. In the field of fiber-optic communications, leather cable is usually installed by connecting with optical fiber using optical fiber connectors. Common optical fiber connectors include SC, FC, LC and other types. They have their own characteristics and are suitable for different scenarios. When choosing a fiber optic connector, you need to consider factors such as interface type, transmission rate, and use environment to ensure the matching of the connector with the leather cable and optical fiber.

[0003] At present, the commonly used structure for leather-line optical cable connectors is the threaded clamping type. This structure can clamp the optical cable. However, due to the small clamping force, when the optical cable is pulled by external force, the connector and the optical cable are easy to separate or even be broken, which cannot play a buffering and protective role for the optical cable, affecting the use of the optical fiber. Since the optical fiber is installed in the ferrule hole of the connector, dust is easy to enter the ferrule hole, affecting the transmission of signals between optical fibers.

DETAILED DESCRIPTION

[0036] Refer to the following Figures 1 to 13 The embodiments of the present invention are described in detail. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0037] An optical cable fixing and clamping device for an optical fiber active connector, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 , Fig. 9As shown, it includes a connector housing 1, which is a rectangular structure and is set to pass through from left to right. A contact plate 2 is fixedly installed inside the right port of the connector housing 1, and a wire hole that passes through from left to right is opened on the contact plate 2. The right end of the optical cable 3 is installed in the wire hole, and the left end is installed inside the left side of the connector housing 1. A driving rack 4 located on the front and rear sides of the optical cable 3 is provided on the inner bottom end of the connector housing 1. The driving rack 4 is slidably installed on the connector housing 1 from left to right. Two of the driving racks 4 are respectively provided with rotation shafts 5 on their mutually adjacent sides. The two rotation shafts 5 are respectively rotatably installed on the connector housing 1. Bottom gears 6 are respectively coaxially fixedly installed on the two rotation shafts 5. Each bottom gear 6 is meshed and connected with the corresponding driving rack 4 on the same side. A top gear 7 is coaxially fixedly installed, and each top gear 7 is arranged above the corresponding bottom gear 6. Two moving rods 8 symmetrically arranged front and back are slidably installed on the inner end of the connector housing 1. The moving rods 8 are slidably installed on the inner end of the connector housing 1 front and back. Each moving rod 8 is arranged close to the top gear 7 on the same side. A moving rack 9 is fixedly installed on the top of the two moving rods 8 respectively. Each moving rack 9 is meshed and connected with the corresponding top gear 7 on the same side. A clamping body 10 is fixedly installed on the mutually close ends of the two moving racks 9 respectively. The clamping body 10 is made of rubber. The two clamping bodies 10 are arranged on the front and rear sides of the optical cable 3, and arc grooves are respectively opened on the mutually close ends of the two clamping bodies 10. A driving component is provided on the left side of the two driving racks 4;

[0038] When in use, a person holds the optical cable 3 and inserts it into the wire hole of the contact plate 2 from the left port of the connector housing 1. The driving component makes the two driving racks 4 mesh with the corresponding bottom gears 6 and slide to the right. Each bottom gear 6 rotates with the top gear 7 through the corresponding rotation shaft 5. The two top gears 7 mesh with the corresponding moving racks 9 and the moving rod 8 and gradually approach the optical cable 3. The two clamping bodies 10 gradually approach each other until the outer insulation layer of the optical cable 3 is clamped. Since the clamping bodies 10 are made of rubber, the two clamping bodies 10 can exert a large friction force on the optical cable 3.

[0039] When the external optical cable 3 is pulled, the two clamping bodies 10 always clamp the optical cable 3, so the optical cable 3 will not be separated from the connector housing 1, and can effectively resist vibration and falling, ensuring the stability and safety of optical fiber transmission.

[0040] like Figure 2 , Figure 6 , Fig.13As shown, a baffle plate 11 located on the left side of the two driving racks 4 is fixedly installed inside the connector shell 1, and a bottom port located on the left side of the baffle plate 11 is opened on the bottom end of the connector shell 1, and a right pressing rod 12 is slidably installed inside the bottom port, and a right limiting groove is opened on the side end surface of the right pressing rod 12, and a right clamping plate 13 is slidably installed inside the right limiting groove, and a right pressing ring 14 is fixedly installed on the top of the right clamping plate 13, and a right semicircular hole is opened on the top of the right pressing ring 14, and a right pressing spring 15 is fixedly installed on the right pressing ring 14, and the other end of the right pressing spring 15 is fixedly installed on the top of the right pressing rod 12, and a right lock assembly is provided at the lower end of the connector shell 1.

[0041] like Figure 2 , Fig.10 , Fig.13 As shown, a top port located on the left side of the bottom port is provided on the top of the connector housing 1, a left pressing rod 16 is slidably installed inside the top port, a left limiting groove is provided on the side end of the left pressing rod 16, a left clamping plate 17 is slidably installed inside the left limiting groove, a left pressing ring 18 is fixedly installed on the bottom end of the left clamping plate 17, a left semicircular hole is provided at the bottom end of the left pressing ring 18, a left pressing spring 19 is fixedly installed on the top end of the left pressing ring 18, the other end of the left pressing spring 19 is fixedly installed on the bottom end of the left pressing rod 16, and a left lock assembly is provided at the upper end of the connector housing 1.

[0042] like Figure 5 , Fig.10 As shown, the right lock assembly includes a right limiting box 20, which is fixedly mounted on the bottom end of the connector housing 1 and arranged at the left side of the bottom port. A right push plate 21 is slidably mounted inside the right limiting box 20, and a right push block 22 is fixedly mounted on the outer end of the right push plate 21. A right return spring 23 is fixedly mounted on the left end of the right push plate 21, and the other end of the right return spring 23 is fixedly mounted on the left end of the right limiting box 20. A right card plate 24 is fixedly mounted on the bottom end of the right pressing rod 12, and the right card plate 24 is arranged on the outer side of the bottom end of the connector housing 1.

[0043] like Figure 1 , Fig.10As shown, the left lock assembly includes a left limiting box 25, which is fixedly mounted on the top of the connector housing 1, and the left limiting box 25 is arranged on the right side of the left limiting groove. A left push plate 26 is slidably mounted inside the left limiting box 25, and a left push block 27 is fixedly mounted on the top of the left push plate 26. A left return spring 28 is fixedly mounted on the right end of the left push plate 26, and the other end of the left return spring 28 is fixedly mounted on the right end of the left limiting box 25. A left card plate 29 is fixedly mounted on the top of the left pressing rod 16, and the left card plate 29 is arranged on the outer side of the top of the connector housing 1.

[0044] When in use, a person holds the optical cable 3 and inserts it into the wire hole of the contact plate 2 from the left port of the connector housing 1. At this time, the optical cable 3 is located between the right semicircular hole and the left semicircular hole. Then, the right push block 22 and the right push plate 21 are manually pushed to slide to the left. The right return spring 23 is continuously compressed until the right push plate 21 is completely slid into the inside of the right limiting box 20. Then, the right card plate 24 and the right pressing rod 12 are pushed to slide upward. The right pressing spring 15 pushes the right pressing ring 14 to move upward. The right semicircular hole pushes the optical cable 3 upward until the right pressing ring 14 contacts the inner surface of the upper end of the connector housing 1. At this time, the optical cable 3 is in an upwardly bent state. When the right card plate 24 contacts the connector housing 1, the right push plate 21 is released. Due to the rebound force of the right return spring 23, the top surface of the right push plate 21 contacts the bottom surface of the right card plate 24, thereby blocking the right card plate 24.

[0045] Manually push the left push block 27 and the left push plate 26 to slide to the right, and the left return spring 28 is continuously compressed until the left push plate 26 is completely slid into the inside of the left limit box 25, and then push the left card plate 29 and the left pressing rod 16 to slide downward, and the left pressing spring 19 pushes the left pressing ring 18 to move downward, and the left semicircular hole pushes the optical cable 3 to move downward until the left pressing ring 18 contacts the inner surface of the lower end of the connector housing 1. At this time, the optical cable 3 is in a downward bending state. When the left card plate 29 contacts the connector housing 1, release the left push block 27. Due to the rebound force of the left pressing spring 19, the bottom surface of the left push plate 26 contacts the top surface of the left card plate 29, thereby blocking the left card plate 29 (the shape of the optical cable 3, such as Fig.13 shown);

[0046] When the external optical cable 3 is pulled quickly, the optical cable 3 will move quickly to the left, thereby driving the left pressing ring 18 and the left clamping plate 17 to slide upward, and the left pressing spring 19 will continue to compress. At the same time, the optical cable 3 will also drive the right pressing ring 14 and the right clamping plate 13 to move downward, and the right pressing spring 15 will continue to compress. At this time, the optical cable 3 will be gradually stretched, thereby playing a buffering role for the optical cable 3 and avoiding the optical cable 3 from breaking. Since the two clamping bodies 10 always clamp the optical cable 3, the optical cable 3 will not be separated from the connector, which can protect the optical cable 3.

[0047] When the external pulling force disappears, due to the rebound force of the left pressing spring 19 and the right pressing spring 15 , the right pressing ring 14 and the left pressing ring 18 drive the optical cable 3 to return to the bent state again.

[0048] like Figure 6 , Figure 7 , Figure 8 As shown, the driving assembly includes a guide shaft 30, a positioning block 31 is fixedly installed on the left port of the connector housing 1, and an insertion hole 32 that passes through the left and right is opened on the positioning block 31. The front and rear ends of the right side of the insertion hole 32 are respectively provided with sliding grooves 33, and driving plates 34 are respectively installed in the two sliding grooves 33 for sliding left and right. The two driving plates 34 extend into the interior of the insertion hole 32, and the guide shaft 30 is fixedly installed on the two driving plates 34. The front and rear ends of the right side of the positioning block 31 are respectively provided with mounting holes that pass through the sliding groove 33. Positioning holes are respectively provided at the front and rear ends, and each guide shaft 30 is slidably installed left and right in the mounting hole and the positioning hole on the same side. The right ends of the two guide shafts 30 are respectively fixedly installed with linkage plates 35, and the linkage plates 35 are arranged on the right side of the baffle plate 11. The left end of each driving rack 4 is fixedly installed on the corresponding linkage plate 35. The two guide shafts 30 are respectively sleeved with pressure springs 36, and the pressure springs 36 are arranged between the positioning block 31 and the baffle plate 11. The left ends of the two pressure springs 36 are respectively fixedly installed on the guide shafts 30, and the right ends are fixedly installed on the baffle plate 11.

[0049] like Figure 3 , Fig.11As shown, a tail sleeve 37 is provided on the left side of the connector housing 1, a sliding cavity is provided at the right end of the tail sleeve 37, a buffer ring 38 is installed in the sliding cavity for sliding left and right, a limiting groove is provided in the tail sleeve 37 in the left and right directions, the limiting groove does not pass through the right end of the tail sleeve 37, a limiting strip is fixedly installed on the outer end of the buffer ring 38, the limiting strip is installed in the limiting groove for sliding left and right, due to the limiting of the limiting strip by the limiting groove, the buffer ring 38 will not be separated from the tail sleeve 37, a buffer spring 39 is fixedly installed on the left end of the buffer ring 38, the left end of the buffer spring 39 is fixedly installed on the left end of the tail sleeve 37, an installation cavity is provided at the right end of the buffer ring 38, a fixing ring 40 is fixedly installed in the installation cavity, three slider holes 41 are evenly provided in the fixing ring 40, each of the slider holes 41 is provided with an oblique groove 42, and the oblique groove 42 The left end is tilted downward, and the right end is tilted upward. A limiting slider 43 is installed inside each slider hole 41 for sliding left and right. A sliding block 44 located inside the inclined groove 42 is fixedly installed on each limiting slider 43. The sliding block 44 can slide freely along the corresponding inclined groove 42. A thrust spring 45 is fixedly installed on the left end of each limiting slider 43. The left end of the thrust spring 45 is fixedly installed on the buffer ring 38. A push rod 46 is fixedly installed on the right end of each limiting slider 43. Under normal circumstances, the limiting slider 43 will not separate from the slider hole 41. A locking ring 47 is threadedly installed on the right end of the buffer ring 38. A driving ring 48 is fixedly installed on the right end of the locking ring 47. The tail sleeve 37, the buffer ring 38, and the locking ring 47 are respectively provided with left and right through guide openings, and the sliding cavity on the tail sleeve 37 is connected to the guide opening.

[0050] like Fig.11 , Fig.12 As shown, a threaded tube 49 is rotatably connected to the outer end of the tail sleeve 37, and a friction wheel 50 is fixedly installed on the left outer end of the threaded tube 49. The friction wheel 50 is arranged to facilitate driving the threaded tube 49 to rotate, and an internal thread is arranged inside the insertion hole 32;

[0051] When in use, a person holds the right end of the optical cable 3 and inserts it into the guide opening from the left end of the tail sleeve 37, and inserts the optical cable 3 into the guide openings of the buffer ring 38 and the locking ring 47 respectively, and finally inserts the optical cable 3 from the left port of the connector housing 1 into the wire hole of the contact plate 2, completing the initial installation of the optical cable 3;

[0052] Manually push the right push block 22 and the right push plate 21 to slide to the left, and the right return spring 23 is continuously compressed until the right push plate 21 is completely slid into the inside of the right limit box 20, and then push the right card plate 24 and the right pressing rod 12 to slide upward, and the right pressing spring 15 pushes the right pressing ring 14 to move upward, and the right semicircular hole pushes the optical cable 3 to move upward until the right pressing ring 14 contacts the inner surface of the upper end of the connector housing 1. At this time, the optical cable 3 is in an upward bending state. When the right card plate 24 contacts the connector housing 1, release the right push plate 21. Due to the rebound force of the right return spring 23, the top surface of the right push plate 21 contacts the bottom surface of the right card plate 24, thereby blocking the right card plate 24.

[0053] Then push the left push block 27 and the left push plate 26 to slide rightward, and the left return spring 28 is continuously compressed until the left push plate 26 is completely slid into the inside of the left limiting box 25, and then push the left card plate 29 and the left pressing rod 16 to slide downward, and the left pressing spring 19 pushes the left pressing ring 18 to move downward, and the left semicircular hole pushes the optical cable 3 to move downward until the left pressing ring 18 contacts the inner surface of the lower end of the connector housing 1. At this time, the optical cable 3 is in a downward bending state. When the left card plate 29 contacts the connector housing 1, release the left push block 27. Due to the rebound force of the left pressing spring 19, the bottom surface of the left push plate 26 contacts the top surface of the left card plate 29, thereby blocking the left card plate 29. At this time, the optical cable 3 is stuck in the left semicircular hole and the right semicircular hole and becomes a bent state.

[0054] Then, the driving ring 48 and the locking ring 47 are rotated to push the right side of each push rod 46 to move to the left side of the buffer ring 38, and the left end of the locking ring 47 and the right end of the push rod 46 rotate and rub. Since each push rod 46 pushes the limiting slider 43 to slide to the left continuously, the sliding block 44 will slide along the inclined groove 42 until the three limiting sliders 43 clamp the optical cable 3.

[0055] Then, the threaded tube 49 is continuously fed into the internal thread of the insertion hole 32. At the same time, the buffer ring 38 and the right end surface of the threaded tube 49 push the two driving plates 34 and the two guide shafts 30 to move to the right. The two pressure springs 36 are continuously compressed. The two guide shafts 30 push the corresponding driving racks 4 through the linkage plate 35 to mesh with the corresponding bottom gears 6 to slide to the right. Each bottom gear 6 rotates with the top gear 7 through the corresponding rotation shaft 5. The two top gears 7 mesh with the corresponding moving racks 9 and the moving rod 8 and gradually move. Approaching the optical cable 3, the two clamping bodies 10 gradually approach each other until the outer insulation layer of the optical cable 3 is clamped. When the threaded tube 49 is completely threadedly installed in the insertion hole 32, the clamping body 10 at this time also clamps the optical cable 3 to a suitable degree, and finally completes the installation of the tail sleeve 37, the connector housing 1, and the optical cable 3. (During the installation process, the optical cable 3 in the cavity between the positioning block 31 and the left pressing ring 18 may be in a loose state, which will not affect the protection and use of the optical cable 3);

[0056] When the external optical cable 3 is slightly pulled, the three limiting sliders 43 always clamp the optical cable 3, and the optical cable 3 will move a small distance to the left with the buffer ring 38 as a whole, and the buffer spring 39 will be compressed, and the loose optical cable 3 between the positioning block 31 and the left pressing ring 18 will move out to the left, thereby protecting the optical cable 3 and preventing the optical cable 3 from being damaged; when the external pulling force disappears, the buffer ring 38 is driven to return to its initial state due to the rebound force of the buffer spring 39;

[0057] When the external optical cable 3 is pulled greatly, the optical cable 3 will move quickly to the left for a long distance with the buffer ring 38 as a whole, the buffer spring 39 will be compressed, and the slack part of the optical cable 3 will move quickly to the left. At this time, the optical cable 3 will gradually be in a straightened state, thereby driving the left pressing ring 18 and the left clamping plate 17 to slide upward, and the left pressing spring 19 will continue to be compressed. At the same time, the optical cable 3 will also drive the right pressing ring 14 and the right clamping plate 13 to move downward, and the right pressing spring 15 will continue to be compressed. The optical cable 3 gradually moves from a bent state to a straightened state. At this time, the optical cable 3 will gradually be stretched, thereby playing a buffering role for the optical cable 3, and the optical cable 3 will not break, which plays a good protective role; when the external pulling force disappears, due to the rebound force of the buffer spring 39, the right pressing spring 15, and the left pressing spring 19, each component returns to normal;

[0058] By multiple clamping of the optical cable 3, the optical cable 3 can be effectively prevented from loosening or breaking due to external environmental factors, ensuring the stability and safety of the optical cable 3. It can also effectively prevent the optical cable 3 from detaching from the connector, thereby improving the stability of the connector.

[0059] like Figure 1 , Figure 6As shown, a guide plate 51 is fixedly installed at the left end of the baffle plate 11, and a guide hole 52 is opened on the guide plate 51, and the guide hole 52 is set through the baffle plate 11, and the optical cable 3 is installed in the guide hole 52, and the exposed optical fiber is installed in the wire hole of the contact plate 2. A dust cap 53 is detachably installed on the right end of the contact plate 2, and the dust cap 53 is sleeved on the exposed optical fiber to protect the optical fiber. Two observation ports are respectively opened at the front and rear ends of the connector housing 1, and an observation door 54 is detachably installed inside each observation port, which can be installed with screws. The installation of the optical cable 3 can be observed through the observation port, and the observation door 54 can prevent dust from entering the inside of the connector housing 1, and the installation of the optical cable 3 can be guided through the observation port;

[0060] When in use, manually push the right push block 22 and the right push plate 21 to slide to the left, and the right return spring 23 is continuously compressed until the right push plate 21 is completely slid into the inside of the right limit box 20, and then push the right card plate 24 and the right pressing rod 12 to slide upward, and the right pressing spring 15 pushes the right pressing ring 14 to move upward, and the right semicircular hole pushes the optical cable 3 to move upward until the right pressing ring 14 contacts the inner surface of the upper end of the connector housing 1. At this time, the optical cable 3 is in an upward bending state. When the right card plate 24 contacts the connector housing 1, release the right push plate 21. Due to the rebound force of the right return spring 23, the top surface of the right push plate 21 contacts the bottom surface of the right card plate 24, thereby blocking the right card plate 24.

[0061] Then push the left push block 27 and the left push plate 26 to slide rightward, and the left return spring 28 is continuously compressed until the left push plate 26 is completely slid into the inside of the left limiting box 25, and then push the left card plate 29 and the left pressing rod 16 to slide downward, and the left pressing spring 19 pushes the left pressing ring 18 to move downward, and the left semicircular hole pushes the optical cable 3 to move downward until the left pressing ring 18 contacts the inner surface of the lower end of the connector housing 1. At this time, the optical cable 3 is in a downward bending state. When the left card plate 29 contacts the connector housing 1, release the left push block 27. Due to the rebound force of the left pressing spring 19, the bottom surface of the left push plate 26 contacts the top surface of the left card plate 29, thereby blocking the left card plate 29. At this time, the optical cable 3 is stuck in the left semicircular hole and the right semicircular hole and becomes a bent state.

[0062] Then, the threaded tube 49 is continuously conveyed to the internal thread of the insertion hole 32. At the same time, the buffer ring 38 and the right end surface of the threaded tube 49 push the two drive plates 34 and the two guide shafts 30 to move to the right. The two pressure springs 36 are continuously compressed. The two guide shafts 30 push the corresponding drive racks 4 through the linkage plate 35 to engage with the corresponding bottom gears 6 to slide to the right. Each bottom gear 6 rotates with the top gear 7 through the corresponding rotation shaft 5. The two top gears 7 engage with the corresponding moving racks 9 and the moving rod 8 and gradually approach the optical cable 3. The two clamping bodies 10 gradually approach each other until the outer insulation layer of the optical cable 3 is clamped to a suitable degree, thereby completing the installation of the tail sleeve 37 and the connector housing 1.

[0063] Next, open one of the observation doors 54 on the left side, insert a tool into the observation port, rotate the drive ring 48, and the drive ring 48 and the locking ring 47 push the right side of each push rod 46 to move toward the left side of the buffer ring 38. At this time, the left end of the locking ring 47 and the right end of the push rod 46 rotate and rub. Since each push rod 46 pushes the limiting slider 43 to continue to slide to the left, the sliding block 44 will slide along the inclined groove 42 until the three limiting sliders 43 clamp the optical cable 3. This can be used for a variety of pulling forces on the optical cable 3. (The detailed steps are not repeated here. When the optical cable 3 is pulled, please refer to the above steps for details).

[0064] like Figure 6 , Figure 7 , Fig. 9 As shown, the right ends of the two driving racks 4 are respectively fixedly installed with left magnet blocks 55, and the left end of the contact plate 2 is provided with two front-to-back symmetrical long strip holes, and the front and back sides of the left end of the contact plate 2 are respectively installed with sealing rings 56, and each sealing ring 56 is fixedly installed with a rectangular block, and the rectangular block is slidably installed inside the corresponding long strip hole, so that the two sealing rings 56 can only slide forward and backward along the contact plate 2, and the ends of the two rectangular blocks away from each other are respectively fixedly installed with tension springs, and the other end of each tension spring is respectively fixedly installed on the inner wall of the long strip hole, and the inner wall of the semicircular mouth of the two sealing rings 56 is respectively and evenly fixed with sealing cotton rings, and the ends of the two sealing rings 56 away from each other are respectively fixedly installed with right magnet blocks 57, and the left magnet block 55 and the right magnet block 57 are at the same height, and the two left magnet blocks 55 and the two right magnet blocks 57 are respectively magnets of the same sex (positive magnets);

[0065] When in use, the two driving racks 4 carry the left magnet block 55 to slide right synchronously, the left magnet block 55 on the rear side magnetically drives the corresponding right magnet block 57 to move forward, and the left magnet block 55 on the front side magnetically drives the corresponding right magnet block 57 to move backward, and the two tension springs are in a stretched state. When the two clamping bodies 10 clamp the optical cable 3, the two sealing rings 56 tightly wrap the sealing cotton ring on the outside of the optical cable 3. The sealing cotton ring can seal the core hole of the optical fiber to prevent external dust from entering the connector, thereby improving the sealing effect and the stability of optical fiber transmission. After the connector is installed, the personnel install the connector to a suitable position for use;

[0066] When the two driving racks 4 bring the left magnet block 55 to slide synchronously to the left and away from the right magnet block 57 , the two sealing rings 56 will gradually move away from the optical cable 3 to a suitable degree due to the rebound force of the two tension springs.
