Description

Technical Field

[0001] This disclosure relates to a connector adapter assembly, a connector, and an optical fiber connection assembly. Background Technology

[0002] With the large-scale deployment of Fiber To The Home (FTTH), pre-connected products that reduce construction costs, lower technical requirements, and simplify installation are becoming increasingly popular. Currently, most fiber optic connectors and adapters used are industry-standard types. These connectors and adapters were originally designed for indoor fiber optic connections or connections within protected boxes (enclosures). Service activation typically requires opening the enclosure and performing splicing and cable securing within it. To avoid these steps during service activation, fiber optic connectors and adapters with better waterproofing capabilities, which can be pre-installed outside the enclosure, are usually chosen.

[0003] Currently, most outdoor fiber optic connectors and adapters on the market use a screw-on locking method. Due to its inherent characteristics, the screw-on locking method requires leaving space for finger operation around the connector and adapter. In limited installation space, especially in situations with high density requirements, operation is very difficult. Summary of the Invention

[0004] This disclosure provides a connector adapter assembly, including a connector adapter inner liner and a connector outer liner. The connector adapter inner liner is provided with a locking buckle, and the connector outer liner is configured to be sleeved on the connector adapter inner liner. When the connector adapter assembly is connected to an adapter, the locking buckle falls into a locking groove on the adapter to achieve locking, and the connector outer liner limits the locking buckle.

[0005] In some examples, the connector housing is provided with a limiting boss, and the locking buckle includes a snap-fit ​​boss, the limiting boss being configured to limit the snap-fit ​​boss radially along the connector housing when the connector adapter assembly is locked to the adapter.

[0006] In some examples, the connector adapter liner is also provided with a limiting buckle, the inner wall of the connector outer sleeve is provided with a first limiting rib, the connector adapter assembly also includes an elastic element, and the connector outer sleeve is configured to compress the elastic element by mutual abutment of the first limiting rib and the limiting buckle.

[0007] In some examples, the connector adapter liner is also provided with a first limiting release rib, which is integrally connected with the limiting buckle. The first limiting release rib is configured to buckle inward under the compression of the adapter and drive the limiting buckle to buckle inward.

[0008] In some examples, the connector adapter assembly includes a pair of locking latches and a pair of limiting latches, wherein the pair of locking latches are disposed opposite each other in a first direction and the pair of limiting latches are disposed opposite each other in a second direction, the first direction being different from the second direction.

[0009] In some examples, the locking latch is closer to the insertion end of the connector adapter liner than the limiting latch.

[0010] In some examples, the inner wall of the connector jacket is provided with a second limiting rib, which is configured to limit the locking buckle when the connector adapter assembly is locked with the adapter.

[0011] At least one embodiment of this disclosure also provides a connector, including a connector adapter assembly and a connector body provided in any of the above embodiments, wherein the connector body is configured to be detachably connected to the connector adapter assembly.

[0012] At least one embodiment of this disclosure also provides an optical fiber connection assembly, including a connector and an adapter provided in any of the above embodiments, wherein the connector is configured to be detachably connected to the adapter.

[0013] In some examples, the adapter includes a cavity, the outer surface of which is provided with the locking groove; the inner wall of the cavity of the adapter is provided with a second limiting release rib, the second limiting release rib being configured to press the connector adapter liner to release the limiting of the connector outer sleeve.

[0014] The connector adapter assembly, connector, and fiber optic connection assembly provided in at least one embodiment of this disclosure have a simple structure and do not require screwing the adapter or connector to achieve locking. Locking is achieved simply by inserting the adapter into the connector adapter assembly along the insertion direction, requiring minimal operating space and being easy to operate even in applications with high density requirements. Once locked, the connector outer sleeve limits the locking latch, preventing it from opening and deforming, thus ensuring strong tensile strength and improving the connector's locking force. Furthermore, since the locking latch is located on the connector assembly, compared to it being located on the adapter, it helps improve the adapter's structural strength and resistance to bending and torsion.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] Where there is no conflict, the embodiments of this disclosure and the features in the embodiments can be combined with each other to obtain new embodiments.

[0026] At least one embodiment of this disclosure provides a connector adapter assembly, including a connector adapter inner liner and a connector outer liner. The connector adapter inner liner is provided with a locking buckle, and the connector outer liner is configured to be sleeved on the connector adapter inner liner. When the connector adapter assembly is configured to mate with an adapter, the locking buckle falls into a locking groove on the adapter to achieve locking, and the connector outer liner limits the locking buckle.

[0027] The connector adapter assembly provided in at least one embodiment of this disclosure has a simple structure and does not require screwing the adapter or connector to achieve locking. Locking is achieved simply by inserting the adapter into the connector adapter assembly along the insertion direction. This requires minimal operating space and is easy to operate even in applications with high density requirements. Once locked, the connector outer sleeve limits the locking latch, preventing it from opening and deforming, thus ensuring strong tensile strength and improving the locking force of the connector. Furthermore, since the locking latch is located on the connector assembly, compared to it being located on the adapter, it helps improve the structural strength of the adapter and its resistance to bending and torsion.

[0028] This connector adapter assembly is used for detachable connection to the connector body, thereby enabling the connector body to be adapted to different adapters and the adapters to be adapted to different connector body structures, thus improving application flexibility.

[0029] Figure 1A-1B This is a schematic diagram of the structure of a connector adapter assembly provided in at least one embodiment of the present disclosure, as shown below. Figure 1A-1B As shown, the connector adapter assembly 100 includes a connector adapter inner liner 20 and a connector outer liner 10, the connector outer liner 10 being configured to be fitted onto the connector adapter inner liner 20. The connector outer liner 10 has a hollow cylindrical structure with a cross-sectional shape, for example, a circle.

[0030] The connector adapter liner 20 includes a locking snap 21. For example... Figure 1B As shown, the connector adapter liner 20 includes a main structure and an elastic cantilever fixed to the root of the main structure (the end away from the insertion end). The elastic cantilever includes a locking snap 21, the end of which is enlarged to form a snap protrusion 210. A gap exists between the elastic cantilever and the main structure for the connector adapter assembly to be inserted into the adapter's slot when mating with the adapter. When the connector adapter assembly 100 is mated with the adapter, the locking snap 21 is used to fall into a locking groove on the adapter to achieve locking, and the connector outer sleeve 10 limits the locking snap 21, thereby increasing the locking force of the connection assembly.

[0031] For example, the main body structure of the connector adapter liner 20 is a columnar structure. The main body structure of the connector adapter liner 20 includes a cavity 24 for accommodating the connector body, which can be detachably connected to the connector adapter liner 20. In this way, the connector body can be adapted to different adapters, and the adapters can be adapted to different connectors, improving application flexibility.

[0032] Since the locking buckle is an elastic and movable component, and the adapter is usually a cavity structure, placing the locking buckle on the adapter is not conducive to improving the structural strength and bending and torsion resistance of the adapter; while the connector adapter liner has become a solid structure when the cavity is inserted into the connector body structure during use, so placing the locking buckle on the connector liner has a smaller impact.

[0033] like Figure 1B As shown, the connector adapter assembly 100 may further include an elastic element 30, which is sleeved on the connector adapter inner liner 20 and configured to be in a compressed state and provide a driving force to the connector outer liner 10 when it is engaged with the connector outer liner 20. For example, the elastic element 30 may be implemented as a spring.

[0034] Figure 2A and Figure 2B The structural schematic diagrams of connector jacket 10 and connector adapter inner liner 20 are shown respectively.

[0035] Figure 2AThe diagram shows a planar structural schematic of the connector jacket 10 and a sectional view of the planar structural schematic along section line AA. Figure 2A As shown, the inner wall of the connector outer sleeve 10 is provided with a first limiting rib 11 and a second limiting rib 12, which can be an integral structure, for example. The first limiting rib 11 is closer to the insertion end of the connector outer sleeve 10 than the second limiting rib 12. For example, the inner wall of the connector outer sleeve 10 is provided with a limiting ring of a certain width, and the two edge portions of the limiting ring are respectively implemented as the first limiting rib 11 and the second limiting rib 12.

[0036] A limiting boss 13 may also be provided on the inner wall of the connector outer sleeve 10. This limiting boss 13 is used to limit the locking buckle 21 when the connector adapter assembly and adapter are locked, thereby increasing the locking force of the connection assembly. The limiting boss 13 is located on the side of the first limiting rib 11 away from the second limiting rib 12. For example, the limiting boss 13 is integrated with the first limiting rib 11.

[0037] Figure 2B The diagram shows a planar structural schematic of the connector adapter liner 20 and a sectional view of the planar structural schematic along section line BB. Figure 2B As shown, a limiting buckle 22 can also be provided on the connector adapter inner liner 20. The limiting buckle 22 is used to abut against the first limiting rib 11 to limit the connector outer sleeve 10 and compress the elastic member 30. After the connector outer sleeve is unfastened, the connector outer sleeve moves under the drive of the compression elastic force, causing the limiting boss 13 to move above the locking buckle 21 to limit the locking buckle 21.

[0038] refer to Figure 1B The locking latch 21 and the limiting latch 22 are located at different positions in the circumferential direction of the connector adapter liner 20. For example, in the axial direction of the connector adapter liner, the locking latch 21 is closer to the insertion end of the connector adapter liner 20 than the limiting latch 22.

[0039] For example, such as Figure 2B As shown, the connector adapter liner 20 is provided with a pair of locking buckles 21 and a pair of limiting buckles 22. The pair of locking buckles 21 are arranged opposite each other in the first direction D1, and the pair of limiting buckles 22 are arranged opposite each other in the second direction D2. The first direction D1 and the second direction D2 are different, for example, they are orthogonal.

[0040] For example, such as Figure 1BAs shown, the main body structure of the connector adapter liner 20 has a rectangular cross-sectional shape, that is, the main body structure is a rectangular columnar structure. The pair of locking buckles 21 are disposed on a pair of opposite sides of the rectangular column, and the pair of limiting buckles 22 are disposed on another pair of opposite sides. For example, the first direction D1 and the second direction D2 are parallel to two adjacent sides of the rectangular cross-section, respectively.

[0041] In other examples, the main structure of the connector adapter liner 20 is cylindrical, and the first direction D1 and the second direction D2 are different radial directions of the cylinder.

[0042] like Figure 2B As shown, the inner wall of the connector adapter liner 20 is provided with a thread 25, which is used to mate with the adapter thread on the connector body to fix the connector adapter liner 20 to the connector body. For example, the thread is provided at the root of the main structure of the connector adapter liner 20. For example, along the axial direction of the adapter liner 20, the limiting buckle 22 is closer to the thread 25 than the locking buckle 21.

[0043] For example, such as Figure 2B As shown, the connector adapter liner 20 is also provided with a first limiting release rib 23, which is integrated with the limiting buckle 22. The first limiting release rib 23 is closer to the insertion end of the connector adapter liner 20 than the limiting buckle 22. The limiting buckle 22 and the first limiting release rib 23 are arranged sequentially along the insertion direction. When the adapter is inserted into the connector adapter liner 20, the first limiting release rib 23 is pressed inward by the slot of the adapter (i.e., it converges towards the axis) and drives the limiting buckle 22 to be pressed inward, thereby causing the first limiting rib 11 to disengage.

[0044] In other examples, the first limiting release rib 23 is not necessary, and the adapter slot can also directly press the limiting buckle 22 inward to disengage the first limiting rib 11.

[0045] At least one embodiment of this disclosure also provides a connector, including the connector adapter assembly 100 provided in any of the above embodiments and a connector body, the connector body being configured to be detachably connected to the connector adapter assembly.

[0046] Figure 3A A schematic diagram of the structure of a connector provided in at least one embodiment of the present disclosure is shown. As shown, the connector 200 includes a connector adapter assembly 100 and a connector body 40. At least a portion of the connector body 40 (such as a connector plug) extends into and is fixed within the cavity of the connector adapter liner 20, that is, the connector adapter liner 20 is sleeved on the connector body 40.

[0047] Figure 3B and 3C A schematic diagram and a cross-sectional view of the connector body 40 are shown respectively. Figure 3B-3C As shown, the connector body 40 includes a connector plug 41, an adapter nut 42, a tail sleeve 44, a connector optical cable 43, a heat shrink tubing 45, a top support 46, a seal 47, a rear sleeve 48 (e.g., a rate rear sleeve), a rear sleeve 52 (e.g., a metal rear sleeve), a ferrule 51, and a crimping ring 53.

[0048] The connector plug 41 is used for mating with an adapter. A ferrule 51 and a ferrule spring are installed within the space formed by the top support 46 and the connector plug 41. One end of the ferrule spring abuts against the ferrule 51, and the other end abuts against the end face of the top support 46. For example, the ferrule 40 can be a single-core ferrule, a dual-core ferrule, or a multi-core ferrule; it can be MPO type, SC type, or dual LC type. This embodiment does not limit the specific type.

[0049] The crimping ring 53 crimps the connector optical cable 43 and crimps the reinforcing member inside the connector optical cable 43 to the rear sleeve 52 to secure the connector optical cable 43 to the connector body. The heat shrink tubing 45 heat shrinks the connector optical cable 43 and the connector together to seal the optical cable and the connector, thereby forming a waterproof and dustproof sealing structure at the rear end of the connector.

[0050] The adapter thread on the adapter nut 42 matches the thread 25 of the connector adapter liner, thereby securing the connector body to the connector adapter assembly; the seal 47 is used for sealing with the adapter assembly. A tail sleeve 44 is also provided at the tail of the connector to protect the connector optical cable 43 from bending damage. The top holder 46 has an internal cavity through which the optical fiber can pass.

[0051] In use, at least a portion of the connector body 40 is inserted into the cavity of the connector adapter liner and secured to await connection with a suitable adapter. The connector adapter assembly 100 can be replaced to allow the connector body to match different adapters, and it can also match different connector bodies, thus enabling the adapter to match different types of connectors, improving application flexibility.

[0052] At least one embodiment of this disclosure also provides an optical fiber connection assembly including a connector and an adapter provided in any of the above embodiments, the connector being configured for detachable connection with the adapter. The adapter includes a cavity for receiving a connector plug and has a locking groove that mates with a locking latch.

[0053] Figures 4A-4C This is a schematic diagram of the structure of an adapter provided in at least one embodiment of this disclosure. For example... Figure 4AAs shown, the adapter 50 includes an adapter body 60, a protective cap 51, a connecting rope 52, and a mounting nut 53. The connecting rope 52 is used to connect the protective cap 51 and the adapter body 60 to prevent the protective cap 51 from being lost. The mounting nut 53 is used for installing the adapter.

[0054] Figure 4B A schematic diagram of the adapter body 60 is shown. Figure 4C A cross-sectional view of the adapter 50 is shown.

[0055] Reference Figures 4A-4C The adapter body 60 is provided with a sealing groove 62. The adapter also includes a sealing element 54, which is disposed in the sealing groove 64 to achieve a seal between the adapter body 60 and the protective cap 51, thereby protecting the insertion end of the adapter.

[0056] like Figure 4B As shown, the adapter body 60 includes a slot 63 for inserting the adapter liner of the connector into the body structure of the adapter when the adapter mates with the connector so as to accommodate the insertion end of the connector into the cavity of the adapter.

[0057] The adapter body 60 is provided with a locking groove 61 and a second limiting release rib 64. The locking groove 61 is provided on the outer surface of the slot 63 and is used to cooperate with the locking buckle 21 on the connector adapter liner to achieve locking. The second limiting release rib 64 is provided on the inner wall of the cavity, for example, on the inner wall of the slot 63. The second limiting release rib 64 is used to squeeze the limiting buckle on the connector adapter liner to release the limiting of the connector outer sleeve when the slot 63 is inserted into the connector adapter liner.

[0058] Figures 5A-5F The diagram illustrates several states during the mating process of the connector and adapter in the fiber optic connection assembly 300 provided in at least one embodiment of this disclosure. The following is in conjunction with... Figures 5A-5F The working principle of the optical fiber connection assembly 300 provided in at least one embodiment of the present disclosure is illustrated by way of example, but this is not intended to limit the present disclosure.

[0059] Figure 5A and Figure 5B This diagram shows a cross-sectional view of the connector in its initial docking state with the adapter. Figure 5A The cross-section is shown in the case of the locking buckle 21. Figure 5B The cross-section is shown when the limit latch 22 is in position. Figure 5A The lower part shows Figure 5A An enlarged schematic diagram of region A in the middle. Figure 5B The lower part shows Figure 5B A magnified view of region B in the middle.

[0060] like Figure 5A As shown, adapter 50 is used to connect connector 200 and connector 400 provided in this embodiment of the disclosure. For example, connector 400 is a standard connector, and connector 200 is an outdoor connector. One end of the adapter is connected to connector 400, and the other end is to be connected to connector 200.

[0061] In this initial state, the elastic element is in a compressed state, and... Figure 5C The elastic element 30 shown is in the same state. The connector outer sleeve 10 is secured to the connector adapter inner sleeve 20, and their relative positional relationship is the same as... Figure 5C The same as shown. At this time, as... Figure 5A As shown, the limiting boss 13 on the connector jacket 10 is further away from the insertion end of the connector adapter liner than the snap-fit ​​boss 210.

[0062] like Figure 5A As shown, as the adapter slot is inserted into the gap between the elastic cantilever of the connector adapter liner and the main body structure, the locking buckle 21 on the connector adapter liner contacts the slot 63 of the adapter 50, and the locking buckle 21 is pushed up by the slot 63.

[0063] At this time, as Figure 5B As shown, the first limit release rib 23 on the connector 200 has not yet contacted the second limit release rib 64 on the adapter 60, and the limit buckle 22 on the connector adapter liner is abutting against the first limit rib 11 on the connector outer sleeve, and the connector outer sleeve is still in the limit state.

[0064] like Figure 5C As shown, the elastic element 30 is confined within a cavity formed by the mutual abutment of the first limiting rib 11 and the limiting buckle 22, thus being in a compressed state. One end of the elastic element 30 abuts against the second limiting rib 12, thereby applying a compressive elastic force to the connector outer sleeve. For example, the first limiting rib 11 and the second limiting rib 12 are integral structures, with the second limiting rib 11 and the second limiting rib 12 arranged sequentially along the insertion direction of the connector outer sleeve, that is, the first limiting rib 11 is closer to the insertion end of the connector outer sleeve than the second limiting rib 12. Both the first limiting rib 11 and the limiting buckle 22 are formed as protruding inclined blocks, and the protrusion height of the second limiting rib 12 is less than the protrusion height of the first limiting rib 11, thereby leaving space to facilitate the movement of the connector outer sleeve; Reference Figure 5B The first limiting release rib 23 and the limiting buckle 22 are integrated into one structure. The protrusion height of the first limiting release rib 23 is less than the protrusion height of the limiting buckle 22, thereby leaving space for the slot 63 to enter.

[0065] As the connectors are continuously inserted, reaching... Figure 5CThe state shown is as follows. At this time, the first limit release rib 23 on the connector 200 contacts the second limit release rib on the adapter 60 and is pressed inward by the second limit release rib, thereby causing the limit buckle 22 to snap inward. The buckle between the limit buckle 22 and the first limit rib 11 is released, the connector outer sleeve is released from the limit, and the connector reaches the desired state. Figure 5D The state shown.

[0066] At this time, the connector jacket 11 moves forward (i.e., toward the adapter) under the compressive force of the elastic element 30 until it is stopped by the locking protrusion 210 of the locking buckle 21, thus restricting its forward movement. When the locking buckle 21 is not in the locking groove 61, the height of the locking protrusion 210 allows its end face to abut against the end face of the limiting protrusion 13 on the connector jacket along the insertion direction.

[0067] like Figure 5E As shown, as the connector continues to be inserted, the locking clip 21 on the connector adapter liner falls into the locking groove 61 on the adapter, losing its supporting effect on the connector outer sleeve. Under the compressive force of the elastic element, the connector outer sleeve continues to move forward until the limiting boss 13 moves above the locking clip 21, radially limiting or pressing the locking clip 21, restricting its springback, and completing the locking. For example, the surface of the limiting boss 13 contacts the surface of the clip boss 210, generating a force between them, and the limiting boss 13 presses against the clip boss 210. For example, a stop can be provided at a corresponding position on the adapter to prevent the connector outer sleeve from moving further forward, thus maintaining the limiting position. For example, as... Figure 5E As shown, in the locked state, at least a portion of the limiting ring containing the first limiting rib 11 and the second limiting rib 12 (e.g., the second limiting rib 12) also limits or presses the root of the locking buckle 21, further increasing the locking force of the connector.

[0068] Before the locking buckle 21 falls into the locking groove 61, the buckle protrusion 210 abuts against the limiting protrusion 13 on the connector outer sleeve. Before this, the first limiting rib 11 on the connector outer sleeve 10 abuts against the buckle protrusion 210 of the locking buckle 21 on the connector adapter liner. Therefore, when inserting the connector into the adapter provided in this embodiment, it can be operated by holding the connector body (such as holding the tail sleeve or optical cable) or by holding the connector outer sleeve, thereby avoiding misoperation during insertion. In the latter case, the connector outer sleeve can drive the connector body to move forward together.

[0069] like Figure 5EAs shown, after the locking buckle 21 falls into the locking groove 61, the limiting boss 13 moves to the locking buckle 21 to limit it. This not only increases the locking force of the connector, but also the connector jacket 10 forms a protection above the buckle, which can effectively prevent environmental factors from damaging the locking structure. For example, when the connector 200 is located outdoors, the connector jacket 10 can improve the dustproof and waterproof characteristics of the locking structure.

[0070] When the connector and adapter need to be unlocked, simply pull the connector sleeve 10 backward, causing the limiting boss 13 to move away from the locking buckle 21, as shown. Figure 5F As shown, the locking buckle 21 has room to expand outward, so it can expand outward under the force applied by pulling the connector jacket, disengage from the locking groove 61, and unlock.

[0071] The above description is merely an exemplary embodiment of this disclosure and is not intended to limit the scope of protection of this disclosure, which is determined by the appended claims.
