[0033] The application content is further explained below through description of embodiments in conjunction with the accompanying drawings.
[0034] like Figure 1 The figure shows a schematic diagram of the disassembled structure of an outdoor optical fiber connector according to an embodiment of the present application. The outdoor optical fiber connector according to the present application includes a quick connector 1, a stopper 2, a front base 3, a rear base 4, an optical fiber 5, a foot cover 6, a coupling nut 7, a dust cap 8, an O-ring 9 and a hanging rope 10. The quick connector 1, the stopper 2, the front base 3, the rear base 4, the foot cover 6 and the coupling nut 7 are all hollow structures and are coaxially arranged. The O-ring 9 includes a first O-ring 91 and a second O-ring 92. Figure 2 Figure 2 shows the combined structure of an outdoor fiber optic connector according to one embodiment of the present invention. Externally, only the optical fiber 5, foot cover 6, coupling nut 7, dust cap 8, and lanyard 10 are visible. The quick connector 1, stopper 2, front base 3, and rear base 4 are concealed within the combined structure. This protects the core components of the quick connector 1, stopper 2, front base 3, and rear base 4 from exposure during use, extending their usability.
[0035] like Figure 3 As shown, the quick connector 1 includes a main body 11 and a connector 12 disposed within a hollow structure within the main body 11. The connector 12 is at least partially exposed from the main body 11, and the portion exposed from the main body 11 is connected to an external device (not shown) to achieve transmission of optical fiber between the external connection device. Specifically, the optical fiber 5 includes a first optical fiber head 51, a second optical fiber head 52 parallel to the first optical fiber head 51, and a cable 53 fixedly connected to the first optical fiber head 51 and the second optical fiber head 52. The first optical fiber head 51 is coaxially arranged with the cable, and the quick connector 1 is detachably connected to the optical fiber 5.
[0036] like Figure 3The figure shows a schematic diagram of the combined structure of the optical fiber 5 and the quick connector 1 of an embodiment of the present application. The main body 11 is a hollow structure, and a main body groove 112 is provided at one end close to the optical fiber to accommodate the second optical fiber head 52, and a main body limiting structure 111 is provided in the middle part of the main body to accommodate the connector 12. One end of the connector 12 is inserted into the main body 11, and the other end of the connector 12 is at least partially exposed from the other end of the main body 11 away from the optical fiber 5. Specifically, the connector 12 includes a connector 121, a holding structure 122 and an external connector 123 fixedly connected in sequence along the extension direction. The connector 121, the holding structure 122 and the external connector 123 are coaxially arranged. The connector 121 is provided at one end of the connector 12 close to the optical fiber, and the connector 121 is detachably connected to the optical fiber head 51 of the optical fiber 5. The external connector 123 located at the other end of the connector 12 is away from the optical fiber 5, and the external connector 123 is at least partially exposed from the other end of the main body 11 away from the optical fiber 5. The retaining structure 122 is adapted to the main body retaining structure 111 to enable the connector 12 to be retained and connected to the inner sidewall of the main body 11, providing both mobility and stability. Preferably, at least one through-hole is provided on the inner sidewall of the main body retaining structure 111 at a position corresponding to the retaining structure 122, making the connection between the main body 11 and the connector 12 adjustable and more flexible.
[0037] like Figure 4 Figure 1 shows a schematic diagram of the connection between the optical fiber 5 and the connector 12 according to one embodiment of the present application. The connector 12 can rotate about a common axis, and during rotation, the connector 121 remains connected to the first optical fiber connector 51 to maintain connection stability. The first optical fiber connector 51 is coaxially arranged with the external connector 123.
[0038] like Figure 3 As shown, the main body 11 further includes a main body external thread 113 , and the main body external thread 113 is located between the main body limiting structure 111 and the main body groove 112 .
[0039] Figure 5 Schematic diagram of the combined structure of a quick connector 1, a stopper 2 and an optical fiber 5 according to an embodiment of the present application. Figure 5 The figure shows the position limiter 2 covering at least a portion of the quick connector. The position limiter 2 is a hollow structure that covers the outer layer of the quick connector 1 to protect the quick connector 1 and limit its position. The position limiter 2 is a hollow structure with a cavity formed inside. The inner sidewall of the position limiter 2 is provided with internal threads (not shown) that mate with the external threads 113 of the main body to protect the quick connector 1 and limit its position. In this way, the position limiter protects the quick connector 1 during use, extending its service life and ensuring a stable connection between the quick connector 1 and the optical fiber 5.
[0040] like Figure 6As shown in FIG, it is a structural diagram of the rear base 4 of an embodiment of the present application. The rear base 4 is a hollow structure in the shape of a sleeve, and the inner side wall of the rear base 4 is provided with a base internal thread 41. Figure 8 FIG. 1 is a schematic diagram of the structure of the front base 3 according to one embodiment of the present application. The front base 3 is also hollow and coaxially arranged with the rear base 4. The outer wall of the front base 3 is provided with base external threads 31 that match the base internal threads 41, allowing the front base 3 and rear base 4 to be removably threaded together. The front base 3 and rear base 4 can be mounted on the outer layer of the combined structure consisting of the quick connector 1 and the stopper 2.
[0041] like Figure 7 As shown, an end groove 32 is provided at the end of the front base 3 away from the base external thread 31. The shape of the end groove 32 is adapted to the end of the quick connector 1 away from the optical fiber, so that at least part of the main body 11 and the connector 12 are exposed from the end groove 32, so that the connector can be connected to the external device. A first annular groove 33 is provided at a position connected to the base external thread 31 and close to the end groove, and a first O-ring 91 (as shown in FIG. 1 ) is sleeved on the first annular groove 33. Figure 1 As shown), the base inner thread 41 and the base outer thread 31 are more sealed when screwed together, and the sealing of the front base 3 and the rear base 4 is improved to improve the overall protection performance of the outdoor optical fiber connector, thereby preventing water or other substances from entering the outdoor optical fiber connector from the place where the front base 3 and the rear base 4 are screwed together. Figure 7 As shown, a second annular groove 34 is provided on the other side of the first O-ring 91 away from the base external thread 31 for sleeve installation of the second O-ring 92 (as shown in FIG. Figure 1 The second annular groove 34 has a cross-sectional diameter that is larger than the cross-sectional diameter of the first annular groove 33 and smaller than the cross-sectional diameter of the end of the front base 3 having the end groove 32.
[0042] like Figure 8 The figure shows a schematic diagram of the combined structure of the front substrate 3, rear substrate 4, quick connector 1, and optical fiber 5 according to one embodiment of the present application. In the connected state, the rear substrate 4, on the end closest to the optical fiber, covers the first and second optical fiber tips 51, 52 of the optical fiber 5, providing protection for the first and second optical fiber tips 51, 52. At the end of the quick connector 1, away from the optical fiber 5, the main body 11 and connector 12 at least partially pass through the front substrate 3, emerging from the end of the front substrate 3 away from the optical fiber 5, allowing the connector 12 to connect to an external connection device (not shown).
[0043] like Figure 9 FIG. 1 is a schematic diagram of the structure of a coupling nut according to an embodiment of the present invention. The coupling nut 7 includes a limiting external thread 71. Figure 10FIG. 1 is a schematic diagram of the structure of a dust cap 8 according to an embodiment of the present invention. The coupling nut 7 and the dust cap 8 are coaxially arranged. The inner sidewall of one end of the dust cap 8 is provided with a limiting internal thread 82 that mates with the limiting external thread 71, allowing the coupling nut 7 and the dust cap 8 to be threadedly connected.
[0044] like Figure 2 As shown, the outdoor optical fiber connector also includes a foot cover 6 and a hanging rope 10. The foot cover 6, coupling nut 7, and dust cap 8 form the outer shell of the outdoor optical fiber connector. The foot cover 6 is set on the outer layer of the optical fiber, and one end of the foot cover 6 is inserted into the coupling nut 7, and the other end is covered with the cable of the optical fiber 5 to protect the optical fiber. Figure 1 As shown, the foot cover 6 includes a foot cover groove 61. Figure 10 As shown, the top of the dust cap is provided with a dust cap groove 81 and a dust cap through hole 83 fixedly connected to the dust cap groove 81. Figure 2 As shown, a first hanging loop 101 and a second hanging loop 102 are respectively provided at both ends of the hanging rope 10. The first hanging loop 101 is sleeved outside the foot sleeve groove 61, and the second hanging loop is sleeved outside the dust cap groove 81. This prevents the dust cap of the outdoor optical fiber connector from being lost. During use, the dust cap 8 is opened and the outdoor optical fiber connector is connected to other external devices. The dust cap 8 is connected to the outdoor optical fiber connector via the hanging rope 10, making it difficult to lose the dust cap 8. When the outdoor optical fiber connector of the present application does not need to be connected to an external device, the dust cap 8 is screwed onto the coupling nut to protect the internal quick connector 1, limiter 2 and other structures, thereby extending the service life of the product of the present application.
[0045] Preferably, the O-ring is made of silicone, which provides better sealing performance, but may also be made of other materials with equivalent sealing performance.
[0046] Preferably, the optical fiber 5 is an SC optical fiber.
[0047] In summary, the present application provides an outdoor optical fiber connector, comprising a coaxially arranged optical fiber, a quick connector detachably connected to the optical fiber, and a limiter sleeved outside the quick connector; the quick connector comprises a main body with a hollow structure and a connector arranged inside the main body and detachably connected to the main body, one end of the connector is connected to the optical fiber, and the other end of the connector is at least partially exposed from the main body, and the exposed portion of the main body is connected to an external device to achieve transmission between the optical fiber and the external connection device. The present application provides a quick connector to achieve movable cables and connectors at both ends of the connector, and then protects the quick connector through a limiter to ensure the connection stability between the quick connector and the optical fiber. Therefore, it can be flexibly connected and reused outdoors, and can be terminated and plugged on site.
