The present invention relates to an optical fiber connector. For example, the optical fiber connector comprises a first optical fiber, a second optical fiber and a connector assembly, wherein a first threaded cylinder is rotatably sleeved on the first optical fiber, a second threaded cylinder is rotatably sleeved on the second optical fiber, and the connector assembly comprises a first insertion shell, a second insertion shell, a shifting frame and two clamping blocks. For example, the first threaded cylinder is rotatably screwed into the first insertion shell, the end of the first optical fiber is inserted into the first insertion shell, the two clamping blocks are both rotatably arranged in the first insertion shell, and the two clamping blocks are respectively clamped at two opposite sides of the first optical fiber. For example, the second plug shell is inserted into the first plug shell, and the second threaded cylinder is screwed into the second plug shell so that the second optical fiber is inserted between the two clamping blocks. For example, the end of the second optical fiber abuts against the end of the first optical fiber, and the toggle frame is inserted into the two clamping blocks to force the two clamping blocks to be clamped and closed, so as to fix the connection position of the first optical fiber and the second optical fiber.
Referring to fig. 1 to 5, an optical fiber connector includes a first optical fiber, a second optical fiber and a connector assembly 30, the first optical fiber is rotatably sleeved with a first threaded barrel 10, the second optical fiber is rotatably sleeved with a second threaded barrel 20, the connector assembly 30 includes a first insertion shell 31, a second insertion shell 32, a toggle frame 33 and two clamping blocks 35, the first threaded barrel 10 is rotatably screwed in the first insertion shell 31, an end portion of the first optical fiber is inserted in the first insertion shell 31, the two clamping blocks 35 are both rotatably arranged in the first insertion shell 31, the two clamping blocks 35 are respectively clamped at two opposite sides of the first optical fiber, the second insertion shell 32 is inserted in the first insertion shell 31, the second threaded barrel 20 is screwed in the second insertion shell 32 so that the second optical fiber is inserted between the two clamping blocks 35, the end of the second optical fiber abuts against the end of the first optical fiber, and the toggle frame 33 is inserted into the two clamping blocks 35 to force the two clamping blocks 35 to be clamped and closed, so as to fixedly hold the connection position of the first optical fiber and the second optical fiber.
For example, when the optical fiber connector is used, since the toggle frame 33 is inserted into the two clamping blocks 35, the two clamping blocks 35 can be forced to be clamped and closed to hold the connection position of the first optical fiber and the second optical fiber, so that the first optical fiber and the second optical fiber are not easy to be dislocated and loosened.
For example, to facilitate shielding and protecting the first plug housing 31 and the second plug housing 32, the first plug housing 31 and the second plug housing 32 each include a conical housing portion 321 and a plug housing portion 323 connected to each other, and the plug housing portion 323 of the first plug housing 31 and the plug housing portion 323 of the second plug housing 32 are plugged into each other. A threaded hole is formed at an end of the cone portion 321, the first threaded cylinder 10 is screwed into the threaded hole of the first plug housing 31, and the second threaded cylinder 20 is screwed into the threaded hole of the second plug housing 32. The connector assembly 30 further includes an outer casing 38, and the outer casing 38 is sleeved on the first plug casing 31 and the second plug casing 32. The first plug housing 31 and the second plug housing 32 are sleeved by the outer housing 38, so that the first plug housing 31 and the second plug housing 32 can be shielded and protected by the outer housing 38.
For example, to facilitate clamping the first and second optical fibers, the two clamping blocks 35 are bar-shaped and are disposed opposite to each other, and each clamping block 35 includes a pivoting end 351 and a clamping end 353 disposed opposite to each other. A pivot 3515 is disposed at the pivot end 351, and the pivot 3515 is mounted at an end of the plug shell portion 323 of the first plug shell 31 away from the second plug shell 32, so that the clamping block 35 is rotatably connected with the first plug shell 31. The opposite sides of the two clamping blocks 35 are formed with inclined clamping surfaces 352, and the distance between the inclined clamping surfaces 352 of the two clamping blocks 35 gradually increases in a direction toward the second optical fiber. Circular clamping grooves 350 are concavely formed on the two inclined clamping surfaces 352, and the circular clamping grooves 350 of the two clamping blocks 35 are used for clamping the optical fiber together. The two clamping blocks 35 are concavely provided with the circular clamping grooves 350, so that the two circular clamping grooves 350 are matched with the first optical fiber and the second optical fiber, and the two optical fibers can be clamped better.
For example, in order to facilitate the insertion of the dial frame 33, two parallel first plugging grooves 3135 are formed in the plugging shell portion 323 of the first plugging shell 31, two parallel second plugging grooves 3235 are formed in the plugging shell portion 323 of the second plugging shell 32, the two first plugging grooves 3135 are respectively communicated with the two second plugging grooves 3235, the dial frame 33 is inserted into the two second plugging grooves 3235, and the dial frame 33 is received in the outer casing 38. The two first plugging grooves 3135 and the two second plugging grooves 3235 are provided to facilitate the insertion of the dial 33, and the outer casing 38 facilitates the covering of the dial 33.
For example, the invention also provides a connecting method of the optical fiber connector. The connecting method of the optical fiber connector comprises the following steps:
step one, the first threaded cylinder 10 is screwed into the first insertion shell 31 in a rotating manner, so that the end part of the first optical fiber is inserted into the first insertion shell 31;
step two, screwing the second threaded cylinder 20 into the second insert shell 32 to enable the second optical fiber to be inserted between the two clamping blocks 35;
step three, inserting the second insertion shell 32 on the first insertion shell 31, so that the end part of the second optical fiber abuts against the end part of the first optical fiber;
inserting the toggle frame 33 on the two clamping blocks 35 to force the two clamping blocks 35 to be clamped and closed so as to fixedly hold the connection position of the first optical fiber and the second optical fiber; and
and step five, sleeving the outer casing 38 on the first insertion casing 31 and the second insertion casing 32.
For example, it is particularly important that, in order to improve the sealing effect, the outer dimension of the cone portion 321 increases in the direction toward the plug housing portion 323, the first threaded cylinder 10 cannot slide axially relative to the first optical fiber, and the second threaded cylinder 20 cannot slide axially relative to the second optical fiber. The first and second splicing grooves 3135 and 3235 are both parallel to the axial direction of the first optical fiber. The outer casing 38 comprises a hard casing 381 and an elastic cylinder 383, which are connected with each other, the elastic cylinder 383 is movably wrapped on the plug casing portion 323 of the first plug casing 31, one end of the elastic cylinder 383 is fixedly connected to the end portion of the plug casing portion 323 of the first plug casing 31, the other end of the elastic cylinder 383 is connected to the end portion of the hard casing 381, and the hard casing 381 is sleeved on the plug casing portion 323 of the second plug casing 32. The opposite sides of the plug-in shell portion 323 are each provided with a U-shaped groove 3231, each U-shaped groove 3231 forming an elastic fin 3232 on the plug-in shell portion 323, one side of the elastic fin 3232 is convexly provided with an elastic clamping block, the other side is provided with a clamping groove 3234, the clamping groove 3234 is exposed outside the plug shell portion 323, two opposite sides of the hard shell 381 are formed with abutting arms 3815, the end portions of the two abutting arms 3815 are provided with abutting blocks, the two abutting arms 3815 abut against the two elastic fins 3232 of the second plug shell 32 respectively, the two abutting blocks are clamped into the two clamping grooves 3234 respectively, thereby abutting against the two elastic fins 3232 and deflecting towards the two clamping blocks 35 respectively, so that the two elastic clamping blocks respectively clamp the clamping ends of the two clamping blocks 35 to move oppositely, and the two clamping ends are utilized to preliminarily position the second optical fiber. Due to the engagement of the two abutting arms 3815 and the two elastic fins 3232, the hard shell 381 will not contract under the action of the elastic cylinder 383 to return to its original position. The two elastic fins 3232 are pressed by the two pressing arms 3815, so that the two clamping blocks 35 can be deflected to preliminarily clamp and position the second optical fiber. For example, the free end of the elastic fin 3232 faces the elastic cylinder 383, and the free end of the holding arm 3815 faces the second threaded cylinder 20.
For example, in order to facilitate clamping and holding the connection between the first optical fiber and the second optical fiber, a receiving transverse groove 324 is concavely disposed on the plug shell portion 323 of the second plug shell 32, opposite ends of the receiving transverse groove 324 are respectively perpendicularly connected to the two second plug grooves 3235, an initial circular groove 354, an expanding straight groove 355 and a clamping straight groove 356 are disposed on each clamping block 35, the initial circular groove 354 is opened on the pivoting end 351 of the clamping block 35 and is aligned with the end of the first plug groove 3135 facing away from the second plug groove 3235, the expanding straight groove 355 and the clamping straight groove 356 are both connected to the initial circular groove 354, the expanding straight groove 355 and the clamping straight groove 356 both extend to the clamping end 353 of the clamping block 35, the distance between the expanding straight groove 355 and the clamping straight groove 356 on each clamping block 35 gradually increases in the direction toward the clamping end 353, the flared straight slots 355 are adjacent to the angled clamping surfaces 352. The expanding straight groove 355 includes an upper wide groove 3551 and a lower narrow groove 3553 which are vertically communicated, the clamping straight groove 356 includes an upper narrow groove 3561 and a lower wide groove 3563 which are vertically communicated, the width of the upper wide groove 3551 is equal to the width of the lower wide groove 3563, and the width of the upper narrow groove 3561 is equal to the width of the lower narrow groove 3553. The diameter of the initial circular groove 354 is greater than the width of the upper wide groove 3551. The bottom of the end of the clamping straight groove 356 away from the initial circular groove 354 is concavely provided with a circular insertion groove 357. The middle of the initial circular groove 354 is provided with a flexible flap 3545, the flexible flap 3545 has the same shape as the cross section of the initial circular groove 354, and the flexible flap 3545 is aligned with the connection of the upper wide groove 3551 and the lower narrow groove 3553 (or the connection of the upper narrow groove 3561 and the lower wide groove 3563). The toggle frame 33 comprises a toggle beam 331 and two toggle columns 332, wherein the two toggle columns 332 are respectively and vertically connected to two opposite ends of the toggle beam 331. The diameter of the toggle post 332 is less than the width of the upper slot 3561/the lower slot 3553. The bottom end of the toggle post 332 is provided with an enlarged cylinder 3325, and the diameter of the enlarged cylinder 3325 is equal to the width of the upper wide groove 3551/the lower wide groove 3563.
For example, when the second plug housing 32 is inserted into the first plug housing 31, the toggle beam 331 is moved by hand, the two toggle columns 332 are respectively inserted into the initial circular grooves 354 of the two clamping blocks 35 and abut against the flexible stop 3545, the toggle beam 331 is used to drive the two toggle columns 332 to move toward the second plug housing 32, the enlarged cylinders 3325 on the two toggle columns 332 respectively enter the upper wide grooves 3551 of the two expanding straight grooves 355, and move toward the second plug housing 32 to force the clamping ends 353 of the two clamping blocks 35 to move away from each other, so that the second optical fiber is inserted between the two clamping blocks 35. When moving from the initial circular groove 354 toward the second insert housing 32, the two toggle posts 332 can only enter the two expanding straight grooves 355 because the upper narrow groove 3561 of the clamping straight groove 356 is of a smaller width and cannot allow the toggle posts 332 to enter. After the second fiber is inserted, the dial holder 33 can be pulled out upward. The two clamping blocks 35 are now initially positioned by means of the two resilient fins 3232. After the first optical fiber and the second optical fiber are butted, the first optical fiber and the second optical fiber need to be clamped, at this time, the toggle beam 331 is further configured to drive the two toggle columns 332 to be respectively inserted into the initial circular grooves 354 of the two clamping blocks 35 under an external force, and abut against the two flexible blocking pieces 3545 to deform so that the two enlarged cylinders 3325 reach the bottom ends of the initial circular grooves 354, the toggle beam 331 is further configured to drive the two toggle columns 332 to move toward the second insert case 32, the enlarged cylinders 3325 on the two toggle columns 332 respectively enter the lower wide grooves 3563 of the two clamping straight grooves 356, and move toward the second insert case 32 so as to force the clamping ends 353 of the two clamping blocks 35 to approach each other, so as to clamp the joint of the first optical fiber and the second optical fiber by using the clamping ends 353 of the two clamping blocks 35. Thereafter, the dial frame 33 is moved downward by an external force, so that the dial beam 331 is snapped into the receiving transverse groove 324 and the two enlarged cylinders 3325 are inserted into the circular slots 357 of the two clamping blocks 35. Thereafter, the outer casing 38 can be slid to make the hard casing 381 be clamped and covered outside the inserting casing portion of the second inserting casing 32 to shield the first inserting slot, the second inserting slot and the dial frame 33. Since the striking plate 33 is inserted into the bottom end of the initial circular groove 354, the two striking posts 332 can only enter the two clamping straight grooves 356 and cannot enter the expanding straight groove 355 of the lower narrow groove 3553 when moving laterally. The expanding straight groove 355 and the clamping straight groove 356 can select whether to allow the dial 33 to enter or not according to the insertion depth of the dial 33.
By arranging the expanding straight groove 355 and the clamping straight groove 356, the two clamping blocks 35 can be shifted away from each other or clamped by the shifting frame 33, so that the two clamping blocks 35 can be operated from the outside without observing the internal structure by naked eyes. The arrangement of the upper wide groove 3551 and the lower wide groove 3563 enables the toggle frame 33 to selectively enter the expanding straight groove or the clamping straight groove between two positions of moving up and down, thereby improving the convenience and accuracy of operation. Namely, when the dial frame 33 is not inserted deeply, the transverse movement can only force the two clamping blocks 35 to open, and after the insertion is completed, the transverse movement can only clamp the two clamping blocks 35, so that the external operation is convenient to realize, and the connection stability is also improved. The outer casing 38 is provided to improve the appearance and prevent the first plug housing 31 from being separated from the second plug housing 32. Since the diameter of the initial circular groove 354 is large enough, the rotation of the clamping block 35 does not make the position of the initial circular groove 354 separate from the end of the second insertion groove 3235, and the dial frame 33 can still be inserted into the initial circular groove 354.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
