Description

Technical Field

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

[0002] Fiber optic, short for optical fiber, is a fiber made of glass or plastic that conducts light. Its transmission principle is total internal reflection of light. A fiber optic connector is a removable accessory that connects two optical fibers. It precisely connects the two ends of the optical fibers to maximize the coupling of the light energy output by the transmitting fiber into the receiving fiber, minimizing the impact on the system caused by its involvement in the optical link.

[0003] After connecting two optical fibers, the existing optical fiber connector is not airtight enough, so moisture, dust, etc. often enter. Long-term use will cause the optical fiber signal transmission function after the connection to be weakened, and normal connection between the optical fibers cannot be ensured.

[0035] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Reference Figure 1-Figure 3 An embodiment of the present invention provides an optical fiber connector, comprising an outer cover 2, with optical fibers A1 and B6 respectively installed inside the two sides of the outer cover 2. A connector unit A3 and a connector unit B4 are installed on the outer cover 2 for connecting the optical fibers A1 and B6 to the corresponding outer cover 2. A restraint unit 5 is installed on the outer side of the outer cover 2 for connecting the outer cover 2, the connector unit A3 and the connector unit B4 to each other.

[0037] Reference Figure 3 、 Figure 4 and Figure 6 The optical fiber A1 includes a core A11, the outer surface of the core A11 is wrapped with a skin A12, and the connection of the core A11 is fixedly connected to the connecting tube 13. The optical fiber B6 includes a core B61, the outer surface of the core B61 is wrapped with a skin B62, and the connection of the core B61 is fixedly connected to the connecting wire 63. The connecting wire 63 is tightly embedded in the connecting tube 13. Through the connection between the connecting wire 63 and the connecting tube 13, the core A11 and the core B61 are connected, and then the signals between the optical fiber A1 and the optical fiber B6 can be transmitted to each other.

[0038] Reference Figure 3 、 Figure 4 and Figure 7 The connection unit A3 includes a ferrule A31 which is laterally movably installed in the outer cover 2 and is laterally mirrored. A closed connection unit 32 for performing closed connection on the optical fiber B6 is installed on the side of the ferrule A31 close to the center of the outer cover 2. A plurality of through-holes 33 which are circumferentially evenly spaced are reserved on the ferrule A31. The side of the ferrule A31 which is farther from the center of the outer cover 2 is fixedly connected to the partition part A35. The radial span of the inner surface of the ferrule A31 is consistent with the radial span of the outer surface of the optical fiber A1 and the radial span of the outer surface of the optical fiber B6.

[0039] Reference Figure 3 、 Figure 4 and Figure 7 The connecting unit B4 includes a ferrule B41 which is laterally movably mounted on the outer surface of the ferrule A31. A plurality of silicone platforms A42 which pass through the through-hole 33 and re-tighten the optical fiber B6 are circumferentially and evenly spaced on the inner surface of the ferrule B41 close to the center of the outer cover 2. A barrier portion B44 is mounted on the side of the ferrule B41 which is farther from the center of the outer cover 2.

[0040] Reference Figure 3 and Figures 6-10 The constraint unit 5 includes a rotating cylinder 51 that is screwed to the outer surface of the outer cover 2 and is laterally mirrored. A plurality of right-angle bars 52 for constraining the barrier portion A35 and the barrier portion B44 are circumferentially and evenly spaced on one side of the rotating cylinder 51 that is farther from the center of the outer cover 2. A reset portion 53 is installed in the rotating cylinder 51.

[0041] Reference Figure 3-Figure 5 The outer housing 2 is provided with an insertion port 21, an annular opening A22, and an annular opening B24, which are concentric with the outer housing 2 and arranged along its length. The insertion port 21, annular opening A22, and annular opening B24 are all arranged transversely in the outer housing 2 as mirror images. The insertion port 21 and annular opening A22 are located between a pair of transverse annular openings B24. The connection between the insertion port 21 and the optical fiber B6 matches each other, and the side of the insertion port 21 farther from the center of the outer housing 2 is connected to the annular opening A22. When connecting optical fibers A1 and B6, they are inserted into the corresponding ferrules A31, and the connection between the optical fibers A1 and B6 is inserted into the insertion port 21 until it can no longer be pushed.

[0042] Reference Figure 3-Figure 6 The closed connection unit 32 includes a plurality of plastic strips 321 fixedly connected to one side of the ferrule A31 close to the center of the outer cover 2 and arranged at equal intervals in a circular direction. The plastic strip 321 close to the center of the outer cover 2 is fixedly connected to a protrusion 322. A protrusion is provided on the outer surface of the plastic strip 321 close to the center of the outer cover 2. A silicone tube A323 for sealing the optical fibers A1 and B6 is provided in the annular opening A22. The silicone tube A323 is located on the side of the plastic strip 321 close to the center of the outer cover 2.

[0043] Reference Figure 3-Figure 6 The inner side of the outer cover 2 is fixedly connected to a compression tube 23 located between the annular opening A22 and the annular opening B24. The cross-section of the compression tube 23 is a quadrilateral with one side tilted and is located on the side of the protrusion farther from the center of the outer cover 2. The tilted wall of the compression tube 23 close to the center of the outer cover 2 and the protrusion are in contact with each other, and the tilted wall farther from the center of the outer cover 2 and the hoop tube B41 are in contact with each other.

[0044] When the connection between optical fiber A1 and optical fiber B6 is embedded in the embedding interface 21, the silicone tube A323 is clamped on the outer surface of the corresponding optical fiber A1 and optical fiber B6, and the silicone tube A323 changes its shape. The gap between the outer cover 2 and the optical fiber A1 and optical fiber B6 is sealed by the silicone tube A323 to form a sealing space A, thereby enhancing the sealing function of the optical fiber A1 and optical fiber B6 docking with the connecting seat; when assembling the connecting seat, first assemble the clamp tube B41 and the installation clamp tube A31, and then embed the clamp tube B41 and the installation clamp tube A31 into the outer cover 2. During this period, the plastic strip 321 and the protrusion are completely blocked by the compression tube 23 when they are moved into the compression tube 23 and are tilted and changed in shape toward the center of the circle of the clamp tube A31. State, after successful assembly, the protrusion on the plastic strip 321 is now in close contact with the tilted wall of the compression tube 23. Since the protrusion on the plastic strip 321 does not fit the side wall of the silicone tube A323, under the cooperation of its own deformation force, the amplitude of the overall shape change of the plastic strip 321 and the protrusion at this moment is smaller than before, and it is still tilted toward the center of the hoop tube A31. After the optical fiber A1 and the optical fiber B6 are installed, the protrusion 322 is fastened to the outer surface of the optical fiber A1 and the optical fiber B6 to prevent the optical fiber A1 and the optical fiber B6 from falling off from the outer cover 2, thereby strengthening the stability of the assembly of the outer cover 2 and the optical fibers A1 and B6, forming a sealed space B, and enhancing the sealing function of the optical fiber A1 and the optical fiber B6 docking with the connecting seat.

[0045] Reference Figure 3 、 Figure 4 、 Figure 6 and Figure 7 The side of the silicone platform A42 farther from the corresponding hoop tube B41 is tilted toward the center of the outer cover 2. The inner surface of the through-opening 33 closer to the center of the outer cover 2 is reserved with a slope with the same tilt as the silicone platform A42, and the inner surface farther from the center of the outer cover 2 is fixed with a pressing platform 34 for pressing the silicone platform A42.

[0046] The radial span of the outer surface of optical fiber A1 and the radial span of the outer surface of optical fiber B6 are greater than the radial span of the inner surface of silicone platform A42. When the connection between optical fiber A1 and optical fiber B6 is embedded in the corresponding embedding interface 21, the silicone platform A42 changes its shape due to the outward pressure provided by optical fiber A1 and optical fiber B6. The deformation force of the silicone platform A42 itself allows it to be fastened to the outer surfaces of optical fiber A1 and optical fiber B6, thereby tightening optical fiber A1 and optical fiber B6 again, further strengthening the stability of the connection of silicone platform A42, and also forming a sealed space C, thereby strengthening the sealing function of the connection between optical fiber A1 and optical fiber B6 and the connecting seat.

[0047] When disassembling optical fibers A1 and B6, the compression ferrule A31 is moved toward a position close to the center of the outer housing 2. The ferrule A31 pulls the plastic strip 321 toward a position close to the center of the outer housing 2, allowing the compression cylinder 23 and the protrusion to separate. At this time, the plastic strip 321 releases the fastening of optical fibers A1 and B6 under the cooperation of its own deformation force. During the movement, the ferrule A31 pulls the compression platform 34 to move simultaneously, and the compression platform 34 presses the silicone platform A42 outward, allowing the silicone platform A42 to release the fastening of optical fibers A1 and B6, so as to quickly cancel the fastening of optical fibers A1 and B6. Then, the optical fibers A1 and B6 can be pulled out of the outer housing 2, and the connection between optical fibers A1 and B6 can be cancelled.

[0048] If the optical fibers A1 and B6 are pulled outward, while the plastic strip 321 and the silicone platform A42 are fastening the optical fibers A1 and B6, the ferrule A31 and the plastic strip 321 move along with the optical fibers A1 and B6. At this moment, the plastic strip 321 and the entire protrusion are tilted toward the center of the ferrule A31 again in cooperation with the tilted wall of the compression tube 23, thereby strengthening the fastening of the optical fibers A1 and B6. In addition, the silicone platform A42 is also fastened to the optical fibers A1 and B6 again in cooperation with the inner surface of the through-opening 33. Therefore, when the optical fibers A1 and B6 are pulled outward, the optical fibers A1 and B6 will not disintegrate.

[0049] Reference Figure 3-Figure 7 A plurality of silicone platforms B43 are arranged at equal intervals in a circular direction on the outer surface of the hoop tube B41 close to the center of the outer cover 2. The side of the silicone platform B43 farther from the corresponding hoop tube B41 is tilted toward a direction farther from the center of the outer cover 2. The hoop tube B41 is arranged laterally movably inside the annular opening B24. A silicone tube B45 is arranged in the annular opening B24 on the side of the silicone platform B43 farther from the center of the outer cover 2.

[0050] When assembling the connecting seat, first assemble the connecting unit A3 and the connecting unit B4 to each other, and take the assembly of the connecting unit A3 and the connecting unit B4 on one side of the outer cover 2 as an example to illustrate. The hoop B41 is hooped from left to right on the outer surface of the plastic strip 321. At this time, the plastic strip 321 changes its shape inward under the pressure of the hoop B41. When the plastic strip 321 and the silicone platform A42 are attached to each other, the silicone platform A42 changes its shape outward under the cooperation of the pressure force of the plastic strip 321 until the silicone platform A42 and the through-opening 33 are facing each other. At this time, the silicone platform A42 is restored inward to be embedded in the through-opening 33 under the cooperation of its own deformation force, and is on the left side of the pressure platform 34.

[0051] After the connection unit A3 and the connection unit B4 are assembled, the silicone tube B45 is connected to the hoop tube B41, and then the silicone tube A323 is assembled in the ring-shaped opening A22 inside the outer cover 2. Then, the assembled connection unit A3 and the connection unit B4 are pressed into the inner side of the outer cover 2 at the same time. When pressing, the plastic strip 321 first moves into the outer cover 2, and then changes its shape inward under the cooperation of the pressing tube 23. Then, the silicone stage B43 and the silicone tube B45 are compressed and changed in shape at the mouth of the outer cover 2. After the silicone stage B43 and the silicone tube B45 are all moved into the ring-shaped opening B24, the silicone stage B43 and The silicone tube B45 is restored with the cooperation of its own deformation force. At this moment, the silicone platform B43 and the silicone tube B45 are constrained inside the ring-shaped mouth B24, thereby preventing the hoop tube B41 from disintegrating. The barrier part A35 can no longer move toward the inside of the outer cover 2 under the constraint of the outer cover 2, and the protrusion on the plastic strip 321 is in contact with the tilted wall of the compression tube 23. Since the protrusion on the plastic strip 321 is not in contact with the side wall of the silicone tube A323, with the cooperation of its own deformation force, the amplitude of the overall shape change of the plastic strip 321 and the protrusion at this moment is smaller than before, and it is still tilted toward the center of the hoop tube A31.

[0052] After the ferrule B41 is assembled into the outer housing 2, the silicone platform B43 is constrained between the silicone tube B45 and the inner surface of the ring-shaped opening B24, first preventing the ferrule B41 from moving inside the outer housing 2 and causing the silicone platform A42 to become unstable. The silicone tube B45 also seals the gap between the outer housing 2 and the ferrule B41 to form a sealed space D, further strengthening the sealing function of the optical fiber A1 and the optical fiber B6 docking with the connector.

[0053] Reference Figure 3 、 Figure 6 and Figure 10The baffle part A35 includes a baffle plate A351 fixedly connected to the side farther from the center of the outer cover 2 of the hoop tube A31. The baffle plate A351 is located on the outside of the outer cover 2. A plurality of grooves A352 are reserved at equal intervals in a circumferential direction on one side of the baffle plate A351 close to the center of the outer cover 2. A square opening A353 is also reserved on the baffle plate A351, which is one-to-one paired with the groove A352 and connected to one side of the groove A352. The groove A352 is movably connected to the side of the right-angle bar 52 perpendicular to the axial direction of the outer cover 2.

[0054] Reference Figure 3 、 Figure 6 、 Figure 7 and Figure 10 The barrier portion B44 includes a barrier piece B441 fixedly connected to the side of the hoop B41 farther from the center of the outer cover 2. The barrier piece B441 is located on the outside of the outer cover 2. An arched opening 442 is reserved on the barrier piece B441 and is matched with the groove A352 one to one. After the right-angle bar 52 passes through the arched opening 442, it matches with the groove A352. A square opening B443 is also reserved on the barrier piece B441 and is matched with the arched opening 442 one to one and is connected to one side of the arched opening 442. The arched opening 442 and the corresponding square opening B443 form a right-angled opening. One side of the right-angle bar 52 perpendicular to the axial direction of the outer cover 2 is constrained between the barrier piece B441 and the barrier piece A351, and the square opening B443 is directly opposite to the corresponding square opening A353.

[0055] Reference Figure 2 、 Figure 8 and Figure 9 The reset portion 53 includes a plurality of assembly platforms A531 fixedly connected to the inside of the rotating cylinder 51 and arranged at equal intervals in the circumferential direction. A plurality of assembly platforms B533 are arranged at equal intervals in the circumferential direction on the outer surface of the outer cover 2. The assembly platforms B533 are movably installed in the rotating cylinder 51. A beryllium copper bar 532 is fixedly connected between the assembly platforms A531 and the corresponding assembly platforms B533.

[0056] Initially, the side of the right-angle bar 52 perpendicular to the axial direction of the outer cover 2 is located on the side of the groove A352 farther from the square opening A353. At this time, the beryllium copper bar 532 is in a shortened state. The deformation effect provided by the beryllium copper bar 532 to the reverse rotation of the rotating cylinder 51 causes the right-angle bar 52 to press against the inner surface of the groove A352.

[0057] Reference Figure 2 、 Figure 3 and Figures 6-10When assembling the assembled connecting unit A3, connecting unit B4 and outer cover 2, the user first twists the rotating cylinder 51 in the opposite direction to allow the assembly table A531 to press the beryllium copper bar 532, thereby aligning the right-angle bar 52 with the square opening B443 and the square opening A353 in advance. The user constrains the rotating cylinder 51 so that it cannot be reset temporarily, and then moves the hoop cylinder A31 and the hoop cylinder B41 to a position close to the center of the outer cover 2 and embeds them into the outer cover 2. The spacer pieces B441 and the spacer pieces A351 move toward the right-angle bar 52. After the assembly is completed, the right-angle bar 52 now passes through the square opening B443 and its edge extends into the square opening A353. Since the right-angle bar 52 moves to the edge wall of the square opening A353 and the groove A352 is in On the same plane, the rotating cylinder 51 is then released. Under the cooperation of the deformation force of the beryllium copper bar 532, the rotating cylinder 51 pulls the right-angle bar 52 to rotate in the forward direction, so that the side of the right-angle bar 52 perpendicular to the axial direction of the outer housing 2 moves into the groove A352. Finally, the right-angle bar 52 is located on the side of the arched opening 442 farther from the square opening B443 and is in close contact with the inner surface of this side of the arched opening 442. At this time, the side of the right-angle bar 52 perpendicular to the axial direction of the outer housing 2 is embedded between the spacer B441 and the spacer A351. The spacer A351 is restrained by the right-angle bar 52 to prevent the spacer A351 from being accidentally touched and causing the hoop A31 to move toward the center of the outer housing 2, thereby causing the closed connection unit 32 to release the fastening of the optical fibers A1 and B6.

[0058] When the constraint of the right-angle bar 52 on the spacer A351 is removed, the rotating cylinder 51 is rotated in the opposite direction, so that the side of the right-angle bar 52 perpendicular to the axial direction of the outer cover 2 moves from the groove A352 to the square opening A353 facing the square opening. The right-angle bar 52 removes the barrier created by the spacer A351, and then presses the spacer A351 toward the center of the outer cover 2. The right-angle bar 52 passes through the square opening A353, thereby facilitating the disassembly of the closed connection unit 32 and the silicone platform A42.

[0059] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
