Description

Technical Field

[0001] Embodiments of this disclosure relate to the field of fiber optic active connector technology, and more specifically, to a waterproof fiber optic active connector. Background Technology

[0002] Fiber optic connectors are passive optical devices used to enable detachable connections between optical fibers and between optical fibers and other optical devices (such as light sources and detectors). Fiber optic movable connectors, a type of fiber optic connector, are connectors that can be repeatedly plugged in and removed, primarily used in scenarios requiring frequent connection or disconnection, such as equipment interconnection in fiber optic communication systems and the connection of fiber optic testing instruments to optical fibers. Fiber optic movable connections are devices that can be easily installed and removed, aiming to minimize external interference at the fiber optic connection point by connecting optical fibers.

[0003] Some existing fiber optic connectors use bolts for fastening, which makes maintenance or replacement difficult. Furthermore, in humid environments, moisture and humid air can enter the fiber optic connection area through the gaps, affecting the connection quality and even damaging the connector, thus reducing the practicality of existing fiber optic connectors. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a waterproof fiber optic active connector to solve the technical problems of poor waterproof performance and low practicality in the prior art.

[0005] According to one aspect, at least one embodiment of this disclosure provides a waterproof fiber optic connector, including a sleeve and a first connector. A second connector is fixedly connected to one end of the sleeve. An optical fiber is fixedly connected to one end of both the first and second connectors. A mating seat is fixedly connected to the other end of the second connector. A pin is fixedly connected to the other end of the first connector. The connector also includes a snap-fit ​​assembly, a sealing sleeve, and a quick-release assembly. The snap-fit ​​assembly is disposed on the first connector to fix the sleeve and the first connector. The sealing sleeve is fitted onto the first connector, and the outer wall of the sealing sleeve slides against the inner wall of the sleeve. The quick-release assembly is disposed on the outer wall of the sleeve for removing the first connector.

[0006] Preferably, to facilitate the insertion and stability of the first connector into the sleeve and to connect the mating seat and the pin, the snap-fit ​​assembly includes two snap-fit ​​connectors, snap-fit ​​holes, a connecting plate, and a connecting spring. The first connector has a slot that mates with the snap-fit ​​connector, and the snap-fit ​​connector slides against the inner wall of the slot. The inner wall of the sleeve has a snap-fit ​​hole that mates with the snap-fit ​​connector. The first connector has a movable groove that mates with the connecting plate. One end of the connecting plate is fixedly connected to one end of the snap-fit ​​connector, and one end of the connecting spring is fixedly connected to the other end of the connecting plate, while the other end is fixedly connected to the inner bottom wall of the movable groove.

[0007] Furthermore, in order to remove the first connector from the sleeve, the quick-release assembly includes a fixed base, a compression plate, a handle, and two compression springs. One end of the fixed base is fixedly connected to the outer wall of the sleeve. The fixed base has a through-hole. The inner walls of the through-hole and the snap-fit ​​hole are slidably engaged with the compression plate. One end of the handle is fixedly connected to one end of the compression plate. The two compression springs are symmetrically arranged at both ends of the top of the fixed base. The two ends of the compression springs are respectively fixedly connected to the other end of the handle and the fixed base.

[0008] Furthermore, in order to increase the sealing between the second connector and the sleeve, a sealing ring is fitted at one end of the second connector, and the outer wall of the sealing ring fits against the inner wall of the sleeve.

[0009] As a further aspect of this application, in order to ensure accurate docking of the mating seat and the pin and maintain airtightness, the first connector and the second connector form a sealed docking cavity within the sleeve, and the mating seat and the pin cooperate with each other.

[0010] As a further aspect of this application, in order to allow the snap-fit ​​connector to move into the movable slot and prevent the spring from moving out of the movable slot, the movable slot is connected to the slot, and the cross-sectional area of ​​the movable slot is larger than the cross-sectional area of ​​the slot.

[0011] Based on the aforementioned scheme, in order to maintain sealing during the movement of the extrusion plate, the through-hole, the snap-fit ​​hole, and the slot are all connected, and sealing rings are provided on the inner walls of the through-hole and the snap-fit ​​hole.

[0012] Furthermore, in order to facilitate the transfer of the snap-fit ​​connector into the moving groove when the first connector moves along the inner wall of the sleeve, two snap-fit ​​connectors are symmetrically arranged at both ends of the outer wall of the first connector. One end of the snap-fit ​​connector is arc-shaped, and one end of the sleeve is provided with an arc-shaped groove that matches the snap-fit ​​connector.

[0013] The beneficial effects of the embodiments disclosed herein are as follows:

[0014] 1. In this disclosure, through the cooperation of the first connector, sleeve, snap-fit ​​assembly and quick-release assembly, the snap-fit ​​connector is aligned with the arc-shaped groove, and the first connector is moved horizontally along the inner wall of the sleeve to insert the snap-fit ​​connector into the snap-fit ​​hole. This fixes the first connector in the sleeve. When the snap-fit ​​connector is inserted into the snap-fit ​​hole, the ferrule and the mating seat are mated, so that the two optical fibers are stably connected. Then, by pushing the handle downward, the snap-fit ​​connector is fully inserted into the slot and moving slot. Subsequently, the first connector is pulled horizontally to move along the inner wall of the sleeve and remove it from the sleeve. This removes the first connector from the sleeve, which is convenient for subsequent replacement, easy to operate, and practical.

[0015] 2. In this disclosure, by providing a sealing sleeve, a sealing ring, and a sealing ring, the sealing performance of the optical fiber connector can be maintained, preventing moisture from entering the sealed mating cavity in a humid environment, thus achieving a waterproof effect.

[0029] like Figures 1-5 The diagram illustrates a waterproof fiber optic connector according to an embodiment of this disclosure, comprising a sleeve 1 and a first connector 2. A second connector 3 is fixedly connected to one end of the sleeve 1. To increase the sealing between the second connector 3 and the sleeve 1, a sealing ring 19 is fitted onto one end of the second connector 3. The outer wall of the sealing ring 19 fits against the inner wall of the sleeve 1. An optical fiber 4 is fixedly connected to one end of both the first connector 2 and the second connector 3. A mating seat 5 is fixedly connected to the other end of the second connector 3. A pin 6 is fixedly connected to the other end of the first connector 2. To ensure accurate mating of the mating seat 5 and the pin 6 and maintain a tight seal, the first connector 2 and the second connector 3 form a sealed mating cavity 20 within the sleeve 1. The mating seat 5 and the pin 6 cooperate with each other. The connector also includes a snap-fit ​​assembly, a sealing sleeve 7, and a quick-release assembly.

[0030] like Figure 3 and Figure 5As shown, a snap-fit ​​assembly is disposed on the first connector 2 to fix the sleeve 1 and the first connector 2. To facilitate the insertion of the first connector 2 into the sleeve 1 and maintain stability, and to connect the mating seat 5 and the pin 6, the snap-fit ​​assembly includes two snap-fit ​​connectors 8, snap-fit ​​holes 10, a connecting plate 11, and a connecting spring 13. The first connector 2 has a slot 9 that mates with the snap-fit ​​connector 8. The snap-fit ​​connector 8 slides against the inner wall of the slot 9. One end of the snap-fit ​​connector 8 is arc-shaped and mates with the first connector 2 (with the same curvature). This facilitates the movement of the first connector 2 along the inner wall of the sleeve 1. The snap-fit ​​connector 8 is compressed and transferred into the moving groove 12. Two snap-fit ​​connectors 8 are symmetrically arranged at both ends of the outer wall of the first connector 2. One end of the snap-fit ​​connector 8 is arc-shaped. One end of the sleeve 1 has an arc-shaped groove 22 that mates with the snap-fit ​​connector 8. The inner side wall of the sleeve 1 has a snap-fit ​​hole 10 that mates with the snap-fit ​​connector 8. The first connector 2 has a moving groove 12 that mates with the connecting plate 11. In order to allow the snap-fit ​​connector 8 to move into the moving groove 12 and to prevent the spring from moving out of the moving groove 12, the moving groove 12 is connected to the slot 9. The cross-sectional area of ​​the moving groove 12 is larger than the cross-sectional area of ​​the slot 9. The area is such that one end of the connecting plate 11 is fixedly connected to one end of the snap-fit ​​connector 8, one end of the connecting spring 13 is fixedly connected to the other end of the connecting plate 11, and the other end is fixedly connected to the inner bottom wall of the moving groove 12. It should be noted that an anti-slip layer is fitted onto the connecting plate 11, and the anti-slip layer adheres to the inner wall of the moving groove 12. By holding the first connecting head 2 and the optical fiber 4, the two snap-fit ​​connectors 8 are aligned with the arc-shaped groove 22, and the first connecting head 2 is moved horizontally along the inner side wall of the sleeve 1. During the movement, the snap-fit ​​connector 8 is squeezed by the inner wall of the arc-shaped groove 22, and the snap-fit ​​connector 8 squeezes the connecting plate 11, connecting... The connecting plate 11 presses down on the connecting spring 13. The connecting spring 13 retracts, causing the connecting plate 11 and the snap connector 8 to move downwards. After the snap connector 8 is transferred into the moving groove 12, the first connector 2 can drive the optical fiber 4 to move "smoothly" in the sleeve 1. When the snap connector 8 moves to the snap hole 10, the connecting spring 13 pushes the connecting plate 11 and the snap connector 8 toward the snap hole 10, so that the snap connector 8 is inserted into the snap hole 10. In this way, the first connector 2 is fixed in the sleeve 1. When the snap connector 8 is inserted into the snap hole 10, the ferrule 6 and the docking seat 5 are docked, so that the two optical fibers 4 are connected.

[0031] like Figure 2 As shown, a sealing sleeve 7 is fitted on the first connector 2. The outer wall of the sealing sleeve 7 slides against the inner wall of the sleeve 1. The sealing sleeve 7 is made of rubber and has good elasticity. By setting the sealing sleeve 7 and the sealing ring 19, the two optical fibers 4 can be connected in the sleeve 1 and the sealing can be maintained, so as to prevent water vapor from entering the sealing docking cavity 20 in a humid environment.

[0032] like Figure 3 and Figure 4As shown, the quick-release assembly is located on the outer wall of the sleeve 1 and is used to remove the first connector 2. To remove the first connector 2 from the sleeve 1, the quick-release assembly includes a fixed base 14, a pressing plate 16, a handle 17, and two pressing springs 18. One end of the fixed base 14 is fixedly connected to the outer wall of the sleeve 1. The fixed base 14 has a through-hole 15. The inner walls of the through-hole 15 and the snap-fit ​​hole 10 are slidably fitted with the pressing plate 16. To maintain a seal during the movement of the pressing plate 16, the through-hole 15, the snap-fit ​​hole 10, and the slot 9 are all connected. A sealing ring 21 is provided on the inner walls of the through-hole 15 and the snap-fit ​​hole 10. The pressing plate 16 and the sealing ring 21 are tightly connected. One end of the handle 17 is fixedly connected to one end of the pressing plate 16. Two pressing springs 18 are symmetrically arranged at both ends of the top of the fixed base 14. The two ends of the pressing springs 18 are respectively fixedly connected to the handle 17 and the other end of the fixed base 14. 18 has strong rigidity. When subjected to the light weight or pressure of the handle 17 itself, the compression spring 18 is difficult to deform and does not easily wobble. When the user holds the handle 17 and pushes or pulls the handle 17, the compression spring 18 will displace and shift. When the snap connector 8 is inserted into the snap hole 10, one end of the snap connector 8 is attached to one end of the compression plate 16. One end of the compression plate 16 is attached to the outer side wall of the first connector 2 and is arc-shaped. By pushing the handle 17 downward, the compression plate 16 is moved downward. The compression plate 16 compresses the two compression springs 18, and the compression springs 18 contract. The compression plate 16 pushes the snap connector 8 completely into the slot 9 and the moving slot 12, and then keeps it stable. The first connector 2 is pulled horizontally to move along the inner wall of the sleeve 1 and finally transferred out of the sleeve 1. In this way, the first connector 2 is removed from the sleeve 1, which is convenient for subsequent replacement and operation.

[0033] Working principle: When using this waterproof fiber optic 4 movable connector to connect two fiber optics 4, by holding the first connector 2 and the fiber optic 4, the two clamping heads 8 are aligned with the arc-shaped groove 22, and the first connector 2 is moved horizontally along the inner wall of the sleeve 1. During the movement, the clamping head 8 is squeezed by the inner wall of the arc-shaped groove 22, the clamping head 8 squeezes the connecting plate 11, the connecting plate 11 squeezes the connecting spring 13 downward, the connecting spring 13 contracts and drives the connecting plate 11 and the clamping head 8 downward. After the clamping head 8 is transferred into the moving groove 12, the first connector 2 can drive the fiber optic 4 to move "smoothly" in the sleeve 1. When the clamping head 8 moves to the clamping hole 10, the connecting spring 13 pushes the connecting plate 11 and the clamping head 8 toward the clamping hole 10, so that the clamping head 8 is inserted into the clamping hole 10. In this way, the first connector 2 is fixed in the sleeve 1, and when the clamping head 8 is inserted into the clamping hole 10, the ferrule 6 and the docking seat 5 are docked, so that the two fiber optics 4 are stably connected.

[0034] Then, by pushing the handle 17 downward, the compression plate 16 moves downward, the compression plate 16 compresses the two compression springs 18, the compression springs 18 contract, and the compression plate 16 pushes the snap connector 8 completely into the slot 9 and the moving slot 12. Then, it remains stable and pulls the first connector 2 horizontally to move it along the inner wall of the sleeve 1, and finally removes it from the sleeve 1. This removes the first connector 2 from the sleeve 1, which is convenient for subsequent replacement and operation. Through the setting of the sealing sleeve 7, sealing ring 21 and sealing ring 19, the sealing performance of the optical fiber 4 movable connector can be maintained, preventing moisture from entering the sealing mating cavity 20 in a humid environment.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
