[0023] The fiber optic connector 100 is a connector used in dual core single tube tail cover (Uniboot), a product used in optical fiber communications, and has dual optical fiber sockets so that it can simultaneously accommodate multiple optical fiber cable cores (for transmitting and receiving purposes).
[0024] The following description will be given with reference to Figures 2 and 3. Figure 2 is an exploded perspective view of the front of the optical fiber connector 100 according to this embodiment, showing the internal parts of the coupling component 3 in an undisassembled state. Figure 3 is an exploded perspective view of the rear of the optical fiber connector 100 according to this embodiment, showing the coupling component 3 in an undisassembled state.
[0025] The optical fiber connector 100 includes a first metal shell 1, a second metal shell 2, and a plurality of coupling components 3. The first metal shell 1 has an accommodating chamber 10, and one end of the first metal shell 1 includes a plurality of first docking portions 11 located on the coupling component 3 side in FIG. 2 in the longitudinal direction of the accommodating chamber 10, and a first tail cover assembly portion 12 is provided at the other end of the first metal shell 1 in the longitudinal direction.
[0026] The second metal shell 2 covers the first metal shell 1. One end of the second metal shell 2 on the coupling component 3 side includes a plurality of second docking portions 21 corresponding to each of the first docking portions 11, and the other end of the second metal shell 2 in the longitudinal direction includes a second tail cover assembly portion 22 coupled to correspond to the first tail cover assembly portion 12.
[0027] Each coupling component 3 comprises a coupling body 31 and a metal stop portion 35 extending outwardly from a surface of the coupling body 31 .
[0028] The outward direction here means that the end portion extends in a height direction perpendicular to the longitudinal direction described above, from the end portion opposite the first metal shell 1 in FIG. 2, gradually increasing in height as it approaches the first metal shell 1 in the longitudinal direction, and generally extends at an upward angle of about 30 degrees.
[0029] A positioning portion 311 is provided at the side end of each coupling body 31 facing the first metal shell in FIG. 2, and each positioning portion 311 is connected to each first docking portion 11 and each second docking portion 21, respectively.
[0030] After each coupling component 3 is attached to the first metal shell 1, the second metal shell 2 is attached to the first metal shell 1 so as to cover the positioning portion 311 of each coupling component 3. For details, please refer to Figures 8, 9, and 11.
[0031] The first metal shell 1 and the second metal shell 2 are made of metal materials, which provides a robust structure that prevents breakage, and also has high and low temperature resistance, making it suitable for use in low temperature as well as high temperature environments, thereby extending the service life of the optical fiber connector 100.
[0032] 2 and 3, in this embodiment, the first tail cover assembly 12 of the first metal shell 1 includes a first semicircular casing structure 121. The second tail cover assembly 22 of the second metal shell 2 includes a second semicircular casing structure 221.
[0033] When the first metal shell 1 is assembled with the second metal shell 2, the first semicircular casing structure 121 and the second semicircular casing structure 221 are connected, and the first semicircular casing structure 121 and the second semicircular casing structure 221 are combined to form a long tube. For details, please refer to Fig. 25. In addition, a plurality of projections and recesses are formed on the outer surface of the long tube.
[0034] The fiber optic connector 100 further includes a compression ring 5 and a tail cover 6. The compression ring 5 is inserted into the first semicircular casing structure 121 and the second semicircular casing structure 221.
[0035] The compression ring 5 is crimped so that the compression ring 5 comes into contact with each of the projections and recesses and is fixed in place, and the frictional force is increased by the area of the multiple projections and recesses. The tail cover 6 is connected to the compression ring 5 and is the outer sheath of the optical fiber.
[0036] In this embodiment, as shown in Figures 1 to 3, two coupling components 3 are used. However, the scope of the present invention is not limited thereto, and in other embodiments, three or more coupling components 3 may be used.
[0037] Taking two coupling components 3 as an example, the coupling components 3 are arranged side by side. The coupling body 31 of each coupling component 3 has a rectangular parallelepiped structure. A space area (not indicated) exists between each coupling component 3 such that a gap remains between each coupling component 3.
[0038] Next, explanation will be made with reference to Fig. 4 to Fig. 6. Fig. 4 is an exploded perspective view of the coupling component 3 according to this embodiment, and Fig. 5 is a perspective view of the coupling component 3 according to the embodiment of the present invention, in which the positioning portion of the coupling body 31 has a square structure. Fig. 6 is a cross-sectional view of the coupling component 3 according to this embodiment.
[0039] In this embodiment, each coupling component 3 includes a core tube component 32 and a lid 33 , and the coupling body 31 has a through hole 310 .
[0040] The core tube component 32 includes a pin 321 mounted in the through hole 310 and a resilient part 322 sleeved (inserted) over the pin 321 .
[0041] The pin 321 of the core tube component 32 includes a ceramic core tube that covers the optical fiber (core wire) and makes it flush with the core hole of the core tube.
[0042] 4 to 6, in this embodiment, the lid 33 is made of a plastic material or a metal material. The lid 33 also includes two elastic arms 331 and a hook portion 332 disposed on each elastic arm 331. The coupling body 31 includes a plurality of buckle holes 312 located on the inner wall of the through hole 310.
[0043] When the elastic member 322 is placed in the through hole 310 and one end of the elastic member 322 is pressed against the pin 321, the lid 33 is inserted into the opening of the through hole 310. The lid 33 is placed at the opening of the through hole 310 and presses the other end of the elastic member 322.
[0044] When each elastic arm 331 is inserted into the through hole 310, the side end of each elastic arm 331 is pressed against the inner wall of the through hole 310 and swings relatively. Next, the lid 33 is pressed against the through hole 310, and the side ends of each elastic arm 331 and each hook portion 332 are inserted into the through hole 310.
[0045] When each hook portion 332 is aligned with each buckle hole 312, each elastic arm 331 jumps out in the opposite direction due to its own repulsive force. Each hook portion 332 is fixed so as to engage with each buckle hole 312, and the elastic part 322 is positioned within the through hole 310.
[0046] Next, a description will be given with reference to Figs. 7 to 9. Fig. 7 is a view showing the appearance of the first metal shell 1 and the coupling component 3 when assembled based on this embodiment, and shows a state in which the square-structured positioning portion 311 of the coupling body 31 is engaged with the first concave groove 114 of the first docking portion 11. Fig. 8 is a perspective view showing the appearance of the press piece 4 assembled to the first metal shell 1 based on this embodiment. Fig. 9 is a perspective view showing the appearance of the second metal shell 2 based on the embodiment of the present invention, showing a state in which the second metal shell 2 has the second lock portion 24 and the second docking portion 21 is formed in a rectangular shape.
[0047] In this embodiment, the first docking portion 11 includes a first concave groove 114 and first positioning grooves 115 located on both sides of the first concave groove 114. The positioning portion 311 includes an extension block 314 and positioning protruding blocks 315 located on both sides of the extension block 314. Each positioning protruding block 315 is engaged with each first positioning groove 115.
[0048] In this embodiment, the second docking portion 21 of the second metal shell 2 includes a second groove 214 that is coupled to the positioning portion 311 of the coupling component 3 corresponding to the first groove 114 .
[0049] In this embodiment, the first groove 114 has a rectangular structure (as shown in FIGS. 2 and 3) or an arc structure (as shown in FIG. 17).
[0050] In this embodiment, the second groove 214 has a rectangular structure (as shown in FIGS. 2, 3, 9 and 19) or an arc structure (as shown in FIGS. 10 and 18).
[0051] In this embodiment, the second groove 214 has a rectangular structure (as shown in FIGS. 2, 3, 9 and 19) or an arc structure (as shown in FIGS. 10 and 18).
[0052] Taking the rectangular second groove 214 as an example, when the second docking part 21 is coupled with the first docking part 11, the rectangular second groove 214 corresponds to the rectangular first groove 114 and is fixed around the square extension block 314 of each coupling body 31 respectively.
[0053] Taking the second groove 214 having an arc-shaped structure as an example, when the second docking part 21 is coupled with the first docking part 11, the second groove 214 having an arc-shaped structure corresponds to the first groove 114 having an arc-shaped structure and is respectively engaged around the extension block 314 having a circular structure of each coupling body 31.
[0054] Also, in this embodiment, the extension block 314 is a square structure (as shown in Figures 3 and 5) or a circular structure (as shown in Figures 16-17).
[0055] Taking the extension block 314 with a square structure as an example, when the extension block 314 of each coupling body 31 is respectively mounted into the first groove 114 of the first metal shell 1, the extension block 314 with a square structure is locked into the corresponding first groove 114 with a rectangular structure (shown in Figures 7 to 8).
[0056] Taking the extension block 314 having a circular structure as an example, when the extension block 314 of each coupling body 31 is respectively mounted into the first groove 114 of the first metal shell 1, the extension block 314 having a circular structure is engaged (locked) with the first groove 114 having an arc-shaped structure (shown in Figures 16 and 17).
[0057] Description will be made with reference to Figures 8, 9, and 11. Here, Figure 11 is a perspective view showing the front appearance of the optical fiber connector 100 according to this embodiment, showing a state in which the second metal shell 2 is provided with the second locking portion 24 and does not have the press piece 4.
[0058] In this embodiment, the first metal shell 1 and the second metal shell 2 can be combined by locking, but is not limited thereto.
[0059] Taking the locking method as an example, positioning posts 13 are formed on both sides of the first metal shell 1. The first metal shell 1 has a first locking portion 14 located in the accommodation chamber 10, and the second metal shell 2 has positioning holes 23 on both sides, and the second metal shell 2 is provided with a second locking portion 24.
[0060] Taking the locking method as an example, there are positioning posts 13 on both sides of the first metal shell 1. The first metal shell 1 has a first locking portion 14 located in the accommodation chamber 10, and the second metal shell 2 has positioning holes 23 on both sides, and the second metal shell 2 is provided with a second locking portion 24.
[0061] The screw 9 is screwed into the screw hole in the upper surface of the first metal shell 1, and the first locking portion 14 and the second locking portion 24 are locked and fixed.
[0062] 12, 13, and 14, in this embodiment, the second locking portion 24 has a screw hole provided in the lower surface of the second metal shell 2.
[0063] The screw 9 is fixed in a threaded hole on the underside of the second metal shell 2, and the first locking portion 14 and the second locking portion 24 are fixed so as to be engaged with each other. The reason for exposing the screw 9 to the underside of the second metal shell 2 is to improve the appearance by making the screw 9 invisible from a horizontal surface.
[0064] In this embodiment, the first metal shell 1 and the second metal shell 2 are made of a zinc alloy.
[0065] Next, a description will be given with reference to Figs. 12, 13, and 14. Fig. 12 is a perspective view showing the appearance of the optical fiber connector 100 based on this embodiment from the rear, in which the first metal shell 1 has a first locking portion 14 and is fixed by a screw 9. Fig. 13 is an exploded perspective view of the front of the optical fiber connector 100 according to this embodiment, in which the first metal shell 1 includes the first locking portion 14 and is fitted to the multiple division portions 16 in the receiving chamber 10. Fig. 14 is an exploded perspective view of the rear of the optical fiber connector 100 according to this embodiment, in which the first metal shell 1 includes the first locking portion 14 and is fitted to the multiple division portions 16 in the receiving chamber 10.
[0066] In this embodiment, the first metal shell 1 includes a plurality of divided portions 16 located within the accommodation chamber 10. Each divided portion 16 is disposed on either side of the first lock portion 14.
[0067] When the two optical fibers are installed in the accommodating chamber 10, each optical fiber is restricted between each dividing portion 16 and the two side walls 1a of the first metal shell 1, respectively, to prevent each optical fiber from getting too close to the first locking portion 14.
[0068] Furthermore, when the first locking portion 14 and the second locking portion 24 are connected, the second locking portion 24 of the second metal shell 2 prevents breakage of each optical fiber.
[0069] Description will be given with reference to Figures 2, 3, 7 and 8. In this embodiment, the optical fiber connector 100 further includes a press piece 4 (note that, as will be described later, the press piece 4 can be omitted). The second metal shell 2 has an assembly slot 26, and the press piece 4 has a partition 41 and a press portion 42. The press portion 42 is a curved elastic piece, and the partition 41 and the press portion 42 are integrated together.
[0070] A card insertion groove 15 is formed in both side walls 1a of the first metal shell 1. When installing an optical fiber (core wire) in the accommodation chamber 10 of the first metal shell 1, the partition 41 of the press piece 4 is attached in the chamber 10 of the first metal shell 1.
[0071] After both ends of the partition 41 are engaged with the card insertion grooves 15, the second metal shell 2 is then placed over the first metal shell 1. The pressing portion 42 is exposed from the assembly slot 26 of the second metal shell 2 and pressed against the metal stop portion 35.
[0072] In this embodiment, two coupling components 3 cooperate with each other to use the structure of the press piece 4. However, the present invention is not limited thereto, and each coupling component 3 may be combined with one press piece 4, or three or more coupling components 3 may use only one press piece 4 structure.
[0073] Description will be given with reference to Figures 2, 3, 7 and 8. In this embodiment, the partition 41 of the press piece 4 has a plurality of slots 411 corresponding to the first docking portions 11. Each slot 411 is in an inverted U-shape and has an opening.
[0074] When both ends of partition 41 are attached from top to bottom into each card insertion groove 15, the two optical fibers in storage chamber 10 pass through the openings of each slot 411 and are positioned within each slot 411. Each slot 411 has an inverted U-shape and has an opening structure that makes it easy to install the optical fibers.
[0075] Description will be made with reference to Figures 2, 3, 7, and 8. The press piece 4 is formed to have a small thickness, which ensures the elasticity of the press portion 42 and makes it easy to use by pressing.
[0076] When the thickness of the press piece 4 is reduced, the partition 41 has a predetermined wall between each of the slots 411, and the predetermined wall has a predetermined width to ensure structural strength.
[0077] The depth of each of the grooves 411 of the partition 41 of the press piece 4 is increased so that the apex (also called the top portion) of each of the grooves 411 (the inner curved portion shown in Figure 8) is adjacent to the apex (top portion) of both side walls 1a of the first metal shell 1.
[0078] In this way, when the press piece 4 is attached to the optical fiber, the problem of the inner walls of the grooves 411 rubbing against the optical fiber and breaking it is unlikely to occur.
[0079] In addition, since the depth of each of the slots 411 in the partition 41 is increased, shoulder portions 412 located above each of the slots 411 are formed on both ends of the partition 41 .
[0080] When both ends of the partition 41 are inserted into each card insertion groove 15 in the two side walls 1a of the first metal shell 1, each shoulder portion 412 is exposed from each card insertion groove 15 and is located at the top of the two side walls 1a of the first metal shell 1.

Figure 25 is an oblique view showing the appearance of the first metal shell and the second metal shell after assembly based on this embodiment, and shows the state in which the docking protrusion 17 of the first metal shell 1 is connected to the docking recess 27 of the second metal shell 2.
[0087] In addition, in this embodiment, when the second metal shell 2 is installed on the first metal shell 1, each stop block 29 of the second metal shell 2 is hooked onto each shoulder portion 412 of the press piece 4, and each positioning groove 28 is positioned on each shoulder portion 412 of the press piece 4.
[0088] Next, the second metal shell 2 is placed over the first metal shell 1. Next, the second metal shell 2 is moved over the first metal shell 1 to mate with each docking protrusion 17 and each docking recess 27. Each shoulder portion 412 of the press piece 4 is engaged with each positioning groove 28, and the assembly of the first metal shell 1 and the second metal shell 2 is completed.
[0089] Please refer to FIG. 20, which is a perspective view of the second metal shell 2.
[0090] The second metal shell 2 has an assembly groove 26 and has a rectangular parallelepiped structure together with the second docking part 21. The second metal shell 2 has no stop block 29 on its underside;
[0091] In this embodiment, the stop block 29 is not provided on the lower surface of the second metal shell 2 (that is, the stop block 29 in FIG. 19 is omitted).
[0092] When the second metal shell 2 is placed on the first metal shell 1, the second metal shell 2 is also placed on the first metal shell 1 to cover it.
[0093] Next, the second metal shell 2 is slid on the first metal shell 1, and each docking protrusion 17 is docked with each docking recess 27. Also, each shoulder portion 412 of the press piece 4 is engaged with each positioning groove 28, and the assembly work of the first metal shell 1 and the second metal shell 2 is easily completed.
