Description

Technical Field

[0001] This utility model relates to the field of communication equipment, and in particular to a connection structure for fixing optical fiber heads. Background Technology

[0002] The core purpose of fiber optic connectors and collimators is to efficiently convert guided wavelight propagating in an optical fiber into a parallel beam in free space (or vice versa), while providing a stable and reliable physical interface. Existing collimators and fiber optic connectors are generally connected via threads or snap-fit ​​connections. Threaded connections are inefficient during installation and cumbersome to disassemble. Snap-fit ​​connections are more convenient to install than threaded connections, but they are prone to damage during use, especially after repeated disassembly and installation, where they may fail due to aging and embrittlement. Current fiber optic connector and collimator connection structures rarely combine the advantages of ease of installation and durability. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a connection structure for fixing the fiber optic head, which aims to provide a connection structure for the fiber optic head and the fiber optic collimator, while meeting the requirements of convenient installation and durability.

[0004] To achieve the above objectives, this utility model provides a connection structure for fixing an optical fiber head, the connection structure comprising: a first outer shell and a second outer shell;

[0005] One end of the first housing is provided with an optical fiber mounting hole for fixing the optical fiber head, and the other end of the first housing is provided with a receiving cavity for accommodating the optical fiber head and the first elastic body. A pin mounting hole is provided on the top surface of the first housing at a position corresponding to the first elastic body. A first pin is installed in the pin mounting hole and is supported on the first elastic body.

[0006] The second housing is provided with an optical fiber ferrule and a collimating lens. A connector is provided at one end of the second housing opposite to the first housing. A first pin hole corresponding to the first pin is provided above the connector. The connector is used to insert into the receiving cavity of the first housing to compress the first elastic body so that the first pin falls into the first pin hole to lock the first housing and the second housing. An optical fiber ferrule fastener is provided at the other end of the second housing.

[0007] Optionally, the receiving cavity of the first outer shell includes a first sub-cavity and a second sub-cavity. The first sub-cavity is used to receive the first elastomer, and the second sub-cavity is used to receive the optical fiber head. The gap formed between the optical fiber head and the second sub-cavity is used to insert the connector.

[0008] Optionally, the first pin is provided with a first limiting wall, which is located within the receiving cavity to prevent the first pin from disengaging from the receiving cavity. The first pin is also used for lifting to separate the first pin from the first pin hole, thereby unlocking the first outer shell and the second outer shell. After unlocking, the first elastic body returns to its original position and continues to support the first pin.

[0009] Optionally, a second limiting wall is provided at the top of the first pin, the second limiting wall being used to prevent the first pin from falling completely into the receiving cavity, and the second limiting wall is a detachable structure.

[0010] Optionally, a sealing structure is provided at the connection between the first housing and the second housing, the sealing structure being used to seal and protect the fiber optic head and the collimating lens.

[0011] Optionally, the first elastomer includes a spring, natural rubber, and synthetic rubber.

[0012] Optionally, the diameter of the fiber mounting hole used to fix the fiber head is matched with the diameter of the tail of the fiber head. The fiber mounting hole fixes the tail of the fiber head, thereby achieving overall fixation of the fiber head.

[0013] The beneficial effects of this utility model are as follows: 1. This utility model achieves a quick-connect, insert-type locking connection structure by setting a first elastic body, a first pin, and a first pin hole. Compared with threaded connections, this utility model reduces the cumbersome process of multiple rotations, allowing for immediate connection and efficient and rapid installation. Compared with snap-fit ​​connections, this utility model greatly reduces the risk of aging and embrittlement, and even after multiple installations and disassemblies, damage is rare, achieving the advantages of being sturdy and durable. 2. The first pin of this utility model is also provided with limiting walls with different functions, which can solve the problem of the first pin being easily dislodged or lost.

[0014] In summary, this utility model provides a connection structure for an optical fiber head and an optical fiber collimator that can simultaneously meet the requirements of convenient installation and durability. Attached Figure Description

Therefore, they should not be construed as limitations on this patent.

[0021] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0022] The applicant's research revealed that the core purpose of fiber optic connectors and collimators is to efficiently convert guided wavelight propagating in the fiber into a parallel beam in free space (or vice versa), while providing a stable and reliable physical interface. Existing collimators and fiber optic connectors are generally connected via threads or snap-fit ​​connections. Threaded connections are inefficient during installation and cumbersome to disassemble. Snap-fit ​​connections are more convenient to install than threaded connections, but they are prone to damage during use, especially during repeated disassembly and installation, where they may fail due to aging and brittleness. Current fiber optic connector and collimator connection structures rarely combine the advantages of ease of installation with durability.

[0023] Therefore, this utility model embodiment provides a connection structure for fixing fiber optic heads, such as... Figure 1-4 As shown, the connection structure includes: a first outer shell 1 and a second outer shell 2;

[0024] One end of the first outer shell 1 is provided with an optical fiber mounting hole 12 for fixing the optical fiber head 11, and the other end of the first outer shell 1 is provided with a receiving cavity 14 for accommodating the optical fiber head 11 and the first elastic body 13. A pin mounting hole 15 is provided on the top surface of the first outer shell 1 at a position corresponding to the first elastic body 13. A first pin 16 is installed in the pin mounting hole 15 and the first pin 16 is supported on the first elastic body 13.

[0025] The second outer casing 2 is provided with an optical fiber ferrule 21 and a collimating lens 22. A connector 23 is provided at one end of the second outer casing 2 opposite to the first outer casing 1. A first pin hole 24 corresponding to the first pin 16 is provided above the connector 23. The connector 23 is used to insert into the receiving cavity 14 of the first outer casing 1 to compress the first elastic body 13 so that the first pin 16 falls into the first pin hole 24 to lock the first outer casing 1 and the second outer casing 2. An optical fiber ferrule fastener is provided at the other end of the second outer casing 2.

[0026] It should be noted that, during installation, in this embodiment of the invention, the connector 23 for mounting the fiber optic collimator is inserted into the receiving cavity 14, compressing the first elastic body 13. The first elastic body 13 is compressed, thus no longer supporting the first pin 16, and the first pin 16 falls into the first pin hole 24, achieving a tight lock between the first outer shell 1 and the second outer shell 2. During disassembly, the first pin 16 is lifted to disengage from the first pin hole 24, then the connector 23 is pulled out, the first elastic body 13 returns to its original position, and the first pin 16 is lowered, at which point the first elastic body 13 again supports the first pin 16. The structure when the first outer shell 1 and the second outer shell 2 are separated is as follows... Figure 1 and Figure 2 As shown, the structure when the first outer shell 1 and the second outer shell 2 are locked together is as follows: Figure 3 and Figure 4 As shown.

[0027] In this specific embodiment, the receiving cavity 14 of the first outer shell 1 includes a first sub-cavity and a second sub-cavity. The first sub-cavity is used to receive the first elastic body 13, and the second sub-cavity is used to receive the optical fiber head 11. The gap formed between the optical fiber head 11 and the second sub-cavity is used to insert the connector 23.

[0028] It should be noted that the first elastic body 13 is a hollow rectangular ring structure, and its hollow part matches the size of the second sub-cavity. The size of the first elastic body 13 matches the size of the connector 23. In this embodiment of the utility model, they are rectangles of the same size.

[0029] In this specific embodiment, the first pin 16 is provided with a first limiting wall 161. The first limiting wall 161 is used in the receiving cavity 14 to prevent the first pin 16 from disengaging from the receiving cavity 14. The first pin 16 is also used for lifting so that the first pin 16 and the first pin hole 24 are separated to unlock the first outer shell 1 and the second outer shell 2. After unlocking, the first elastic body 13 returns to its original state and continues to support the first pin 16.

[0030] It should be noted that this structure can effectively prevent the first pin 16 from detaching from the first pin hole 24 and being lost.

[0031] In this specific embodiment, a second limiting wall 162 is provided on the top of the first pin 16. The second limiting wall 162 is used to prevent the first pin 16 from falling completely into the receiving cavity 14. The second limiting wall 162 is a detachable structure.

[0032] It should be noted that the second limiting wall 162 not only prevents the first pin 16 from falling completely into the receiving cavity 14, which would cause installation difficulties, but also facilitates the lifting of the first pin 16 during disassembly.

[0033] In this specific embodiment, a sealing structure is provided at the connection between the first outer shell 1 and the second outer shell 2. The sealing structure is used to seal and protect the fiber optic head 11 and the collimating lens 22.

[0034] It should be noted that the sealed structure prevents dust or other interfering substances from entering the fiber optic head 11 and the collimator.

[0035] In this specific embodiment, the first elastomer 13 includes a spring, natural rubber, and synthetic rubber.

[0036] In this specific embodiment, the diameter of the fiber mounting hole 12 used to fix the fiber head 11 is matched with the diameter of the tail of the fiber head 11. The fiber mounting hole 12 fixes the tail of the fiber head 11, thereby achieving overall fixation of the fiber head 11.

[0037] This embodiment of the invention achieves a quick-connect, insert-type locking connection structure by providing a first elastic body 13, a first pin 16, and a first pin hole 24. Compared to threaded connections, this embodiment reduces the cumbersome process of multiple rotations, allowing for immediate connection and efficient, rapid installation. Compared to snap-fit ​​connections, this embodiment significantly reduces the risk of aging and embrittlement, and even after multiple installations and disassemblies, damage is rare, achieving the advantages of robustness and durability.

[0038] The first pin 16 of this utility model embodiment is also provided with limiting walls with different functions, which can solve the problem that the first pin 16 is easy to fall off and be lost.

[0039] In summary, this utility model embodiment provides a connection structure between the fiber optic head 11 and the fiber optic collimator, which can simultaneously meet the requirements of convenient installation and durability.

[0040] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
