Description

Technical Field

[0001] The embodiments of the present application relate to the field of optical communication technology, and in particular to an optical fiber adapter and a fiber splitter box. Background Art

[0002] With the development of the fifth generation mobile communication technology (Fifth Generation Mobile Networks or Technology, 5G) / Fifth Generation Fixed Network (Fifth Generation Fixed Network, F5G) and pre-connection technology, outdoor single-core connectors have become necessary products for fiber-to-the-home and access network distribution segments.

[0003] In the process of building fiber-to-the-home, the current connection methods are as follows:

[0004] (1) Use on-site quick connectors to achieve optical path connection: This type of connector is supported by industry standards, has good interoperability, and has a mature industry chain. However, it has high requirements on the operator's skill level and it is difficult to uniformly control product quality.

[0005] (2) Use optical fiber hot melting to achieve optical path connection: Fiber optic connection is achieved through hot melting or automated no-damage technology (ANT) welding method, which has a mature industrial chain and supporting equipment, avoiding the problem of interface compatibility. However, the welding process requires a dedicated welding machine, which is complicated to operate and inefficient, and cannot meet the needs of large-scale rapid deployment.

[0006] (3) Use pre-terminated products to achieve optical path connection: The pre-terminated fiber adapter is installed on the fiber splitter box in a through-the-wall connection mode and provides an external interface, which can be plugged and played in an outdoor environment without opening the fiber splitter box door. Although the construction is convenient, the optical path connection can be achieved by simply inserting the pre-terminated fiber connector into the pre-terminated fiber adapter. However, there is a lack of unified standards for pre-terminated products of different brands and interface types, resulting in the need to equip a variety of pre-terminated cables with different interfaces during subsequent network construction and user installation, which brings great inconvenience to maintenance personnel and also increases the complexity and cost of spare parts.

[0007] In summary, no effective solution has been proposed in the related art. Summary of the invention

[0022] The embodiments of the present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] At present, the Square Connector (SC) is a fiber optic active connector composed of a single-core plug and a fiber optic adapter. It is an indispensable component in the field of optical communications. It is characterized by a rectangular structure and an elastic clip locking mechanism, including a precision pin key and a pin that is elastic in the direction of the optical axis. It is widely used in fiber to the terminal (Fiber To The x, FTTx) systems.

[0025] With the development of 5G / F5G and pre-connection technology, outdoor single-core connectors have become necessary products for fiber-to-the-home and access network distribution segments. In the process of fiber-to-the-home construction, the following are several common connection methods:

[0026] (1) Use on-site quick connectors to connect the optical path.

[0027] SC field quick connectors are interoperable interfaces supported by industry standards, with a mature industry chain and good interoperability among brands. However, when using field quick connectors, there are high requirements for the operator's skill level, and it is difficult to uniformly control product quality.

[0028] (2) Use the optical fiber hot-melt method to achieve optical path connection.

[0029] Hot-melt / ANT fusion splicing has a mature industry chain and supporting equipment support, avoiding the problem of interface compatibility. However, when hot-melting the optical cable, a fusion splicer is required, which is inconvenient to operate and inefficient.

[0030] (3) Use pre-terminated products to achieve optical path connection.

[0031] The pre-terminated fiber adapter is installed on the fiber splitter box in a through-the-wall connection mode and provides an external interface. The pre-terminated fiber adapter has a protection level of up to IP55 to IP68, which can be plug-and-play without opening the fiber splitter box in outdoor application environments. Especially during construction, you only need to insert the pre-terminated fiber connector into the pre-terminated fiber adapter to achieve the connection of the optical fiber; there is a single / double locking structure between the pre-terminated fiber adapter and the pre-terminated fiber connector, which can ensure that the pre-terminated fiber adapter and the pre-terminated fiber connector have a high tensile strength.

[0032] However, there is no unified standard for the interface of pre-terminated products, and the pre-terminated interface is essentially still an optical physical interface, and its guiding, docking, sealing and locking all require matching structures to achieve. Once the fiber splitter box (including pre-terminated fiber optic adapter) is installed, its interface is a unique structural form. Future network construction and user installation must have matching pre-terminated fiber optic connectors (the fiber optic connectors are prefabricated on pre-terminated cables). In other words, once fiber splitters with different interfaces are used, maintenance personnel will have to equip pre-terminated cables with different interfaces for connection, which brings great inconvenience to maintenance personnel and also increases the complexity and cost of spare parts. Therefore, there is an urgent need for a plug-and-play and flexible pre-terminated fiber optic adapter.

[0033] In view of the above problems, an embodiment of the present application provides an all-in-one pre-terminated fiber optic adapter, wherein the pre-terminated fiber optic adapter is a fiber optic connection component that has completed fiber optic termination and testing before leaving the factory, and is used to quickly and conveniently establish a fiber optic network connection on site to improve installation speed and connection quality. The all-in-one pre-terminated fiber optic adapter is mainly composed of an adapter component and an adapter component arranged inside the adapter component, wherein the adapter component includes an adapter body, and the adapter component includes a replaceable adapter, and the corresponding adapter can be replaced according to different types of pre-terminated fiber optic connectors, thereby achieving a matching connection with different types of pre-terminated fiber optic connectors.

[0034] Furthermore, the all-in-one pre-terminated fiber optic adapter can be installed on a fiber splitter box (also referred to as a pre-terminated fiber splitter box), and one or more pre-terminated fiber optic adapters can be installed on the pre-terminated fiber splitter box, wherein the pre-terminated fiber optic adapter can also be used as an intermediate transfer adapter or an extension adapter.

[0035] Figure 1 is a schematic diagram of the disassembly of the basic components of the all-in-one optical fiber adapter according to an embodiment of the present application, such as Figure 1As shown, the basic components of the all-in-one fiber optic adapter include: an adapter body 1, an adapter adapter sealing ring 2, a ceramic sleeve 3, an adapter body dust cap 4, an adapter adapter fixing nut 5, an adapter adapter locking and unlocking device 6, an adapter mounting nut 7, and a connecting rope 17.

[0036] Exemplarily, the adapter body 1 is mounted on the pre-terminated fiber splitting box and is fixed on the pre-terminated fiber splitting box by means of the adapter mounting nut 7 .

[0037] Specifically, the adapter mounting nut 7 is used to pass the adapter body 1 through the fiber splitting box mounting hole from the outside of the fiber splitting box and then fix it on the fiber splitting box by screwing, and compress the adapter adapter sealing ring 2 by screwing to achieve waterproof and dustproof. Alternatively, it can also be the boss on the right side of the adapter body 1. After passing the adapter body 1 through the fiber splitting box mounting hole from the inside of the fiber splitting box, the adapter mounting nut 7 is used to fix it on the fiber splitting box by screwing, and the adapter adapter sealing ring 2 is compressed by screwing to achieve waterproof and dustproof.

[0038] Exemplarily, the ceramic sleeve 3 is installed inside the adapter body 1, the adapter adapter sealing ring 2 is installed in the groove of the adapter body 1, the adapter body dust cap 4 is aligned with the adapter body 1 and sleeved on the end of the adapter body 1, and then the adapter adapter fixing nut 5 is sleeved on the adapter body dust cap 4, and the adapter adapter lock and unlocker 6 is used to squeeze the adapter body dust cap 4 and the adapter adapter sealing ring 2 through threaded rotation, thereby achieving the effect of sealing and waterproofing, and achieving the effect of fastening the adapter body 1 and the adapter body dust cap 4.

[0039] The adapter body dust cap 4 is connected to the adapter body 1 through a connecting rope 17 to prevent the adapter body dust cap 4 from falling off and being lost during disassembly.

[0040] Figure 2 is a schematic diagram of the assembly of the all-in-one optical fiber adapter basic assembly according to an embodiment of the present application, such as Figure 2 As shown, the embodiment of the present application is a complete schematic diagram after assembling the adapter body 1, the adapter adapter sealing ring 2, the ceramic sleeve 3, the adapter body dust cap 4, the adapter adapter fixing nut 5, the adapter adapter lock and unlocker 6, the adapter mounting nut 7, and the connecting rope 17.

[0041] Figure 3 is a component structure diagram of a fiber optic adapter according to an embodiment of the present application, such as Figure 3 As shown, the optical fiber adapter includes: an adapter component 310 and a switching connector component 320 disposed inside the adapter component;

[0042] The adapter assembly 310 includes an adapter body, which is connected to the fiber splitter box;

[0043] The adapter assembly 320 includes a replaceable adapter, which is detachably connected to the first end of the adapter body via a threaded structure or a snap-on structure.

[0044] In this embodiment, the adapter assembly 310 includes an adapter body 1, which is the basic structure of the fiber optic adapter (also called a pre-terminated fiber optic adapter), responsible for connecting the internal adapter assembly, and is fixedly connected to the pre-terminated fiber distribution box through the adapter mounting nut 7.

[0045] It should be noted that the adapter body 1 can be installed and fixed to the pre-terminated fiber splitter box in two ways. One is to pass through the mounting hole of the pre-terminated fiber splitter box from the outside and then tighten it by threads, and compress the adapter adapter sealing ring 2 to achieve waterproof and dustproof. The other is the boss on the right side of the adapter body 1, which passes through the mounting hole from the inside of the pre-terminated fiber splitter box and then tighten it by threads, and compress the adapter adapter sealing ring 2 to achieve waterproof and dustproof.

[0046] In this embodiment, the adapter assembly is composed of multiple components, and its core component is a replaceable adapter. The adapter usually contains an alignment structure inside for aligning the inserted pre-terminated optical fiber connector to ensure efficient transmission of optical signals. In addition, each adapter is equipped with a corresponding adapter seal ring to establish a waterproof and dustproof sealing barrier between the adapter and the adapter body to protect the optical fiber connection from external environmental factors. And the adapter seal ring usually has good elasticity and can adapt to slight deformation during connection to ensure long-term sealing effect.

[0047] In this embodiment, the adapter is detachably connected to the adapter body 1, and this connection mechanism enables maintenance personnel to flexibly replace the corresponding adapter according to the type of pre-terminated optical fiber connector used on site, thereby achieving compatibility with different types of pre-terminated optical fiber connectors.

[0048] In this embodiment, the adapter is detachably connected to the first end of the adapter body 1 through a threaded structure, the adapter is provided with an external thread, and the corresponding position of the adapter body 1 is provided with an internal thread. By rotating the adapter adapter fixing nut 5, the adapter can be tightly connected to the adapter body 1. The connection mode of the threaded structure provides good tight strength, which can withstand the repeated operation of inserting and removing the pre-terminated optical fiber connector, as well as potential external tension and vibration.

[0049] In this embodiment, the adapter is detachably connected to the first end of the adapter body 1 through a snap-fit ​​structure. In the snap-fit ​​structure setting, the adapter may include one or more snaps, or the adapter body may be provided with a corresponding slot. By pressing or rotating the adapter, it can be quickly snapped into the adapter body 1. Similarly, through the adapter adapter lock and unlock device 6, the connection of the snap-fit ​​structure can be ensured to be stable, which is suitable for the scene where the adapter needs to be frequently replaced.

[0050] The adapter assembly 320 includes a replaceable adapter, which is configured as a flexibly replaceable adapter assembly that can adapt to pre-terminated fiber optic connectors of different specifications, standards and interface types, such as A interface, B interface or C interface, etc., to match a variety of pre-terminated fiber optic connectors.

[0051] Specifically, a replaceable adapter is connected to the first end of the adapter body 1 (such as Figure 1 , that is, one end of the ceramic sleeve 3 is installed) adopts a threaded structure or a clamping structure for detachable connection. Both structures ensure the detachability of the adapter and the stability of the connection. The detachable connection method provides convenience for replacing the adapter.

[0052] In the embodiment of the present application, the adapter and the adapter body 1 are detachably connected through a threaded structure as an example. When the adapter needs to be replaced to adapt to different types of pre-terminated optical fiber connectors, the operator uses the adapter adapter lock and unlock device 6 to unlock the adapter adapter fixing nut 5, removes the current adapter and the adapter body dust cap 4, and installs the new adapter and the corresponding adapter seal ring on the adapter body 1 through threaded rotation. Finally, the adapter adapter fixing nut 5 is re-fixed through the adapter adapter lock and unlock device 6 to tightly connect the new adapter to the adapter body 1. This process is simple and quick, does not require complex tools or professional skills, can quickly complete the replacement of the adapter, and greatly improves the efficiency and flexibility of on-site operations.

[0053] In one embodiment, the adapter assembly further comprises: a ceramic sleeve embedded in the adapter body.

[0054] In this embodiment, the adapter assembly further includes a ceramic sleeve 3 installed inside the adapter body 1. The ceramic sleeve 3 is a component in the optical fiber adapter for accurately centering and guiding the optical fiber. It is usually a finely processed hole to ensure accurate alignment when the optical fiber is inserted and reduce signal loss and reflection loss caused by optical fiber deviation from the center. Due to the high hardness and low thermal expansion coefficient of the ceramic material, it can maintain good dimensional stability in a high temperature environment.

[0055] In one embodiment, the adapter assembly further includes: an adapter adapter fixing nut or an adapter adapter clamping block sleeved at the connection between the adapter and the adapter dust cap.

[0056] In one embodiment, the adapter assembly further comprises: an adapter mounting nut or an adapter clamping block detachably connected to the second end of the adapter body.

[0057] In the embodiment of the present application, the adapter adapter fixing nut 5 and the adapter mounting nut 7 are taken as examples. When the adapter mounting nut 7 is connected, the adapter mounting nut 7 is connected to the second end (such as the adapter body 1) of the adapter body 1 through the threaded structure. Figure 1 , that is, the boss on the right side of the adapter body 1), wherein the adapter mounting nut 7 can also be replaced by an adapter clamping block, both of which can fix the adapter body 1 on the pre-terminated fiber distribution box, while ensuring the sealing of the connection to achieve waterproof and dustproof, and by rotating the adapter adapter fixing nut 5, the adapter can be tightly connected to the adapter body 1.

[0058] In one embodiment, the adapter assembly further comprises: an adapter adapter locker and unlocker detachably connected to the adapter adapter fixing nut or the adapter adapter clamping block.

[0059] In one embodiment, an adapter transition sealing ring is provided at the groove of the adapter body.

[0060] In this embodiment, the adapter assembly also includes an adapter adapter sealing ring 2, an adapter main body dust cap 4, an adapter adapter fixing nut 5, an adapter adapter lock and unlocker 6, etc. The above components together constitute the waterproof and dustproof mechanism of the adapter main body 1 and the locking mechanism of the adapter.

[0061] In one embodiment, the adapter assembly further includes: an adapter dust cap, wherein the adapter dust cap is sleeved on the end of the adapter.

[0062] In one embodiment, an adapter sealing ring is provided between the adapter and the adapter adapter fixing nut or the adapter adapter clamping block.

[0063] In this embodiment, each adapter is equipped with a corresponding adapter sealing ring and adapter dust cap, such as an A-interface adapter sealing ring, a B-interface adapter sealing ring and a C-interface adapter sealing ring, an A-interface adapter dust cap, a B-interface adapter dust cap and a C-interface adapter dust cap. The above-mentioned adapter sealing rings and adapter dust caps cooperate with the adapter adapter sealing ring 2 inside the adapter body, ensuring that even when replacing adapters with different interfaces, good waterproof and dustproof performance can be maintained.

[0065] In this embodiment, during the use of the all-in-one pre-terminated optical fiber adapter, it can be replaced with an A-interface adapter 8 according to user needs. Specifically, the adapter adapter fixing nut 5 is unlocked by the adapter adapter lock and unlocker 6, the adapter body dust cap 4 is removed, and the A-interface adapter 8 is replaced (wherein the A-interface adapter 8 is equipped with an A-interface adapter sealing ring 10), and then the removed adapter adapter fixing nut 5 is installed to fasten the A-interface adapter 8 to the adapter body 1, and then the A-interface adapter dust cap 9 is installed to achieve a dust-proof seal, wherein the A-interface adapter dust cap 9 can be connected to the adapter body 1 using a connecting rope 17 to prevent the components from falling and being lost during disassembly.
