[0002] Currently, for fiber optic connector ferrule assemblies, a locking latch is typically installed around the ferrule and the crimping block. In the locked position, pushing the latch to the locked position creates an interference fit between the latch and the crimping block, allowing the crimping block to press firmly against the fiber optic joint. However, due to the interference fit requirement, the user needs to apply considerable force throughout the process to move the latch to the locked position, making the operation difficult and the assembly efficiency low. Summary of the Invention

[0022] The maximum thickness of the tailstock portion is greater than the maximum thickness of the flexible portion.

[0023] In some embodiments of this application:

[0024] The surface of the clamping part facing away from the receiving cavity is also provided with a transition surface, which is disposed between the first mating surface and the tail shank.

The ferrule is inserted into the tailstock, and the pressing block can press the mating area to clamp the optical fiber mating point, thereby realizing the connection of two optical fibers. The pressing block has a first mating surface with an inclined setting. During the process of pushing the locking latch, the pushing force of pushing the locking latch can gradually increase, and the locking latch gradually forms an interference fit with the pressing block. Therefore, it is not necessary to push the locking block with a large pushing force throughout the entire process as in the prior art, which reduces the user's operating difficulty and improves assembly efficiency.

[0034] The fiber optic connector of the present invention, including the above-described ferrule assembly, can reduce the difficulty of operation for users and improve assembly efficiency. Attached Figure Description

[0073] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0074] Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0075] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a ferrule assembly 100, comprising: a tailstock 1, a ferrule 2, a pressing block 3, and a locking buckle 4.

[0076] Tailstock 1 has a receiving cavity 11, and the surface of tailstock 1 is also provided with an opening 12 communicating with the receiving cavity 11. An optical fiber docking platform 5 is provided inside the receiving cavity 11. An optical fiber docking platform 5 is provided with a docking groove 51 exposed by the opening 12. The docking groove 51 is used to dock optical fibers. The docking groove 51 has a docking area where the optical fiber docking position is located. A first channel 13 and a second channel 14 communicating with the receiving cavity 11 are respectively provided at both ends of tailstock 1. The first channel 13 is used for the optical fiber 500 to pass through.

[0077] The fiber optic docking location refers to the docking point of the fiber optic cable in the docking slot 51, which is located in the docking area.

[0078] The ferrule 2 has a third channel 21 inside for another optical fiber 500 to pass through. The ferrule 2 is also connected to the second channel 14. The two ends of the mating slot 51 are respectively set to the third channel 21 and the first channel 13.

[0079] Please refer to Figure 6-8 The pressing block 3 is placed over the opening 12 and can close the receiving cavity 11. The surface of the pressing block 3 facing away from the receiving cavity 11 is provided with a first mating surface 31. The first mating surface 31 is inclined. The pressing block 3 is used to press the mating area.

[0080] Please refer to Figure 9 The latch 4 is movably fitted onto the tailstock 1. When the latch 4 is pushed to the first mating surface 31, the latch 4 gradually forms an interference fit with the pressing block 3, so that the pressing block 3 presses the mating area tightly.

[0081] In this embodiment, by setting up a ferrule assembly 100, the ferrule 2 is inserted into the tailstock 1, and the pressing block 3 can press the mating area, thereby pressing the mating point of the optical fiber 500 and realizing the connection of the two optical fibers 500. The pressing block 3 has a first mating surface 31 set at an angle. During the process of pushing the latch 4, the pushing force of pushing the latch 4 can gradually increase, and the latch 4 gradually forms an interference fit with the pressing block 3. In the prior art, the resistance caused by the interference fit must be overcome before the push block reaches the locking position, so a large pushing force is required throughout the pushing process of the locking block. However, in this embodiment, the setting of the first mating surface 31 of the ferrule assembly 100 has a certain buffering transition effect, and the pushing force can gradually increase. The interference fit is only formed when the locking position is reached. Therefore, it can reduce the user's operating difficulty and improve the assembly efficiency.

[0082] Please refer to Figure 5 In this embodiment, both ends of the tailstock 1 are cylindrical, and a first channel 13 and a second channel 14 are provided inside. The first channel 13 and the second channel 14 are both cylindrical and are coaxial.

[0083] For ferrule 2, please refer to Figures 10-12 Alternatively, the ferrule 2 can be configured as a separate column. In this case, the fiber optic docking platform 5 can be mounted on the tailstock 1, with the platform 5 serving as the bottom surface of the receiving cavity 11. Alternatively, the ferrule 2 can be configured to include a front ferrule 22, a rear ferrule 23, and a connector 24 connecting the front and rear ferrules 22. Please refer to [reference needed]. Figure 5 The front insert core 22 and the connector 24 are cylindrical. The third channel 21 penetrates the front insert core 22, forming an inner hole extending along its own axial direction. In this case, the fiber optic docking platform 5 is mounted on the rear insert core 23. The connector 24 is inserted into the second channel 14, the rear insert core 23 is located in the receiving cavity 11, and the front insert core 22 is located outside the tailstock 1.

[0084] When the optical fibers 500 are connected, one optical fiber 500 passes through the first channel 13 and enters the connection slot 51, and the other optical fiber 500 passes through the third channel 21 and enters the connection slot 51. The two optical fibers 500 are connected in the connection area of ​​the connection slot 51. After the latch 4 is locked, the pressing block 3 can press the connection point of the two optical fibers 500.

[0085] Please refer to Figure 3 as well as Figures 27-29 When unlocked, the latch 4 is not pushed onto the first mating surface 31, there is a gap between the pressing block 3 and the optical fiber docking platform 5, and the optical fiber 500 can move in the docking groove 51.

[0086] Please refer to Figure 4 as well as Figures 30-32 When locked, the latch 4 is pushed onto the first mating surface 31, and the pressing block 3 is pressed against the optical fiber docking platform 5, which can press the docking point of the two optical fibers 500, and the optical fiber 500 cannot move in the docking groove 51, thus realizing the connection of the optical fiber 500.

[0087] In some embodiments, the angle between the first mating surface 31 and the platform of the optical fiber docking platform 5 is θ, satisfying: 0.3°≤θ≤5°.

[0088] Within this range, while ensuring a buffering transition, the tilt angle is not too large, and the locking buckle 4 is not prone to slippage or unlocking in the locked state. If θ > 5°, the tilt angle is too large, and the locking buckle 4 is prone to slippage and unlocking in the locked state; if θ < 0.3°, there will be a problem with insufficient buffering transition, the labor-saving effect will not be obvious, and it will not significantly reduce the user's operating difficulty.

[0089] In some embodiments, the latch 4 has a second mating surface 41 that mates with the first mating surface 31, and the second mating surface 41 is inclined; when the latch 4 is pushed to the first mating surface 31, the first mating surface 31 gradually forms an interference fit with the second mating surface 41.

[0090] Since the latch 4 in this embodiment is sleeved on the outside of the pressing block 3 and the tail seat 1, the second mating surface 41 is located inside the latch 4 and matches the first mating surface 31.

[0091] The second mating surface 41 is provided, which mates with the first mating surface 31 when the latch 4 is pushed, so as to better achieve the buffering transition effect of the locking process and further save the thrust applied to the latch 4.

[0092] In some embodiments, the pressing block 3 includes a pressing portion 33 and a tail shank portion 34.

[0093] The pressing part 33 is covered at the opening 12 and can close the receiving cavity 11. The first mating surface 31 is provided on the surface of the pressing part 33 away from the receiving cavity 11. The pressing part 33 is provided on the surface facing the receiving cavity 11 with a pressing surface 32. The pressing surface 32 is used to press the mating area.

[0094] The pressing surface 32 presses against the optical fiber docking platform 5, thereby pressing the docking area and ensuring that the locking state can press the optical fiber 500 docking point.

[0095] The tail shank 34 is located at one end of the clamping part 33. The tail seat 1 is provided with a receiving groove 15 for receiving the tail shank 34. The receiving groove 15 is connected to the opening 12 and located on one side of the opening 12. When the tail shank 34 is placed in the receiving groove 15, the latch 4 can be pushed to the first mating surface 31 through the tail shank 34.

[0096] The maximum thickness of the clamping part 33 is greater than the maximum thickness of the tail shank part 34.

[0097] Since the pressing part 33 and the latch 4 are interference-fitted, the surface of the pressing part 33 on the side where the first mating surface 31 is located will be higher than the surface of the tail shank part 34, so as to prevent the latch 4 from being stuck by the tail shank part 34 and affecting the mating with the first mating surface 31.

[0098] The accommodating groove 15 is provided so that a stepped groove can be formed here to accommodate the tail shank portion 34.

[0099] When the pressing block 3 and the locking buckle 4 are interference-fitted, the tail shank 34 will undergo a certain deformation so that the pressing part 33 and the optical fiber docking platform 5 are tightly fitted.

[0100] In some embodiments, the pressing block 3 further includes a flexible portion 35, and the pressing portion 33 and the tail shank portion 34 are connected through the flexible portion 35. When the tail shank portion 34 is placed in the receiving groove 15, the latch 4 can be pushed to the first mating surface 31 in sequence through the tail shank portion 34 and the flexible portion 35. The maximum thickness of the tail shank portion 34 is greater than the maximum thickness of the flexible portion 35.

[0101] The flexible part 35 is designed to deform more easily in the locked state. With this design, the deformation of the pressing block 3 mainly occurs in the flexible part 35, making assembly easier.

[0102] In some embodiments, the pressing part 33 is further provided with a transition surface 39 on the surface opposite to the receiving cavity 11, and the transition surface 39 is disposed between the first mating surface 31 and the tail shank part 34.

[0103] The transition surface 39 allows the latch 4 to be smoothly pushed onto the first mating surface 31.

[0104] In other embodiments, please refer to Figure 10 and Figure 11 ,as well as Figure 13-15 Furthermore, a first groove 36 may be provided on the surface of the pressing block 3 facing away from the receiving cavity 11, and the first groove 36 extends along the pushing direction of the latch 4.

[0105] The first groove 36 allows the manufactured pressing block 3 to have a more uniform thickness, preventing abrupt changes in thickness and preventing the bottom surface of the pressing block 3 from shrinking and deforming. In other words, the pressing surface 32 used for pressing will not shrink and deform, affecting the connection of the optical fiber 500.

[0106] A second groove 37 is provided on the surface of the pressing block 3 away from the receiving cavity 11, and the extending direction of the second groove 37 is intersected with the pushing direction of the latch 4.

[0107] The second groove 37 allows the pressing block 3 at the second groove 37 position to be thinner and have better toughness, similar to the flexible part 35 mentioned above. This allows the deformation of the pressing block 3 to mainly occur here, enabling the pressing block 3 and the optical fiber docking platform 5 to fit tightly together, reducing the difficulty of operation for users, and improving the overall fatigue resistance of the pressing block 3. It can be repeatedly locked and unlocked without the mechanical properties of the pressing block 3 decreasing.

[0108] The pressing block 3 has a third groove 38 on its surface facing the receiving cavity 11. The tail seat 1 has a protrusion 52 that cooperates with the third groove 38. The protrusion 52 is located on both sides of the optical fiber docking platform 5. When the pressing block 3 is placed over the opening 12, the third groove 38 cooperates with the protrusion 52.

[0109] The convex strip 52 is part of the tailstock 1, and the convex strip 52 surrounds the receiving cavity 11, as shown in the figure. Figure 12 As shown.

[0110] The third groove 38 allows the pressing block 3 to be stably placed at the opening 12, improving the overall structural stability during the locking process.

[0111] In addition, a protrusion can be provided on the upper edge of the surface of the pressing block 3 facing the receiving cavity 11. The protrusion is located at the end of the pressing block 3 facing the first channel 13. By providing the protrusion, even in the locked state, the end of the pressing block 3 facing the first channel 13 still has a gap with the optical fiber docking platform 5, but it will not affect the pressing of the optical fiber 500 docking point. Please refer to [reference needed]. Figure 19 , Figure 20 , Figure 33 and Figure 34 In the unlocked state, please refer to... Figure 16-18 The gap between the pressing block 3 and the optical fiber docking platform 5 allows the optical fiber 500 to move in the docking groove 51.

[0112] This embodiment also provides a fiber optic 500 connector, including the aforementioned ferrule assembly 100. Please refer to... Figure 21-22 It also includes a connector body 200 and a front sleeve 300 and a rear sleeve 400 disposed on the body. The rear sleeve 400 and the connector body 200 can be configured for detachable connection methods such as snap-fit ​​or threaded connection. Please refer to [reference needed]. Figure 23 and Figure 24 Alternatively, the two can be flipped and connected, or the front sleeve 300 and the connector body 200 can be integrated. The ferrule assembly 100 is disposed within the connector body 200, with the first channel 13 extending towards the tail sleeve and the third channel 21 extending towards the front sleeve 300. Both types of ferrule assemblies 100 described above can be disposed within the connector body 200; please refer to [reference needed]. Figure 25 and Figure 26 .

[0113] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
