Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to a pluggable optical fiber connector. Background Technology

[0002] Fiber optic connectors are key components in optical communication systems, enabling precise fiber optic connections. Their core function is to minimize optical link coupling loss and ensure transmission reliability. Array-type fiber optic connectors and their built-in fiber arrays have become the mainstream solution for multi-channel transmission. Fiber optic arrays use precision V-groove substrates (such as glass, silicon, or ceramic materials) to position and fix multiple fibers, and adhesives are used for pressure curing to ensure fiber spacing and end-face flatness. However, in existing technologies, fiber optic arrays and connector bodies are often integrated into a single package or permanently bonded, making the fiber optic array non-replaceable. This limitation causes significant problems: when a single fiber is damaged, the end face is contaminated, or individual channels in the array fail, repairs require replacing the entire connector assembly, resulting in resource waste and increased costs.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0026] like Figure 1-6 As shown, a pluggable fiber optic connector according to one embodiment of the present invention includes a fiber optic connector 1, a fixing buckle 2, a positioning base plate 3, and a fixing spring 4. Multiple optical fibers 5 are connected to the fiber optic connector 1 to form a fiber optic array. The fixing buckle 2 has an abutment wall 21 and an upper wall 22 and a lower wall 23 extending horizontally from the abutment wall 21. An accommodating space with an opening is formed between the abutment wall 21, the upper wall 22, and the lower wall 23, and the fiber optic connector 1 is partially inserted into the accommodating space. A locking member 24 is provided on the lower wall 23. The positioning base plate 3 has a positioning groove 31 along its width direction, and the locking member 24 is detachably connected to the positioning groove 31. The fixing spring 4 is fixed to the positioning base plate 3 and located above the positioning groove 31, forming an insertion port between the fixing spring 4 and the positioning groove 31, the height of which is less than the thickness of the fiber optic connector 1.

[0027] The pluggable fiber optic connector operates as follows: Adhesive is applied to the surfaces of the abutment wall 21, upper wall 22, and lower wall 23 of the retaining clip 2. Part of the fiber optic connector 1 is first inserted into the open receiving space formed between the abutment wall 21, upper wall 22, and lower wall 23, and then fixedly connected to the retaining clip 2 with adhesive. During insertion of the fiber optic connector 1 and retaining clip 2 into the socket, the locking member 24 below the retaining clip 2 is locked within the positioning groove 31. Since the height of the socket is slightly less than the thickness of the fiber optic connector 1, and the retaining spring 4 is elastic, the retaining spring 4 abuts against the upper surface of the fiber optic connector 1 to fix the fiber optic connector 1 onto the positioning base plate 3. When the fiber optic cable of the fiber optic connector 1 is damaged, the locking member 24 disengages from the positioning groove 31. Because the retaining spring 4 is elastic, after the locking member 24 disengages from the positioning groove 31, the fiber optic connector 1 can be pulled out of the positioning groove 31 with slight force.

[0028] In the above embodiment, the fiber optic connector 1 of the pluggable fiber optic connector is detachably connected to the positioning base plate 3 via the locking member 24 and the fixing spring 4, so that when the fiber optic 5 is damaged, the fiber optic connector 1 can be detached from the positioning base plate 3 for replacement.

[0029] In one implementation, such as Figure 4-6 As shown, the upper surface of the fiber optic connector 1 has a locking groove 12 extending along its width direction. The upper wall 22 of the fixing buckle 2 is provided with a downwardly protruding part 221. When the fiber optic connector 1 is inserted into the receiving space, the upper wall 22, the abutting wall 21, and part of the lower wall 23 of the fixing buckle 2 all abut against the inserted part of the fiber optic connector 1. The protruding part 221 is configured to be locked in the locking groove 12, and with the glue on the upper wall 22, the abutting wall 21, and part of the lower wall 23 of the fixing buckle 2, the fixing buckle 2 and the fiber optic connector 1 are tightly fixed.

[0030] In one embodiment, the locking member 24 has a certain degree of elasticity. For example... Figure 5 As shown, the locking member 24 includes an inclined extension 241, a horizontal extension 242, and a locking portion 243. The inclined extension 241 extends obliquely downward from the lower wall 23. The horizontal extension 242 extends parallel to the lower wall 23 from the inclined extension 241, and a gap exists between the horizontal extension 242 and the lower wall 23. The end of the horizontal extension 242 protrudes downward to form the locking portion 243. Figure 3 As shown, the bottom surface of the positioning groove 31 is recessed downwards to form a groove 312. The snap-fit ​​part 243 is configured to be operatively snapped into the groove 312 to fix the fiber optic connector 1 in the groove 312.

[0031] The operative engagement of the latching part 243 within the groove 312 can be understood as follows: Due to the elasticity of the locking member 24, the gap between the horizontal extension 242 and the lower wall 23 allows the locking member 24 to move closer to the lower wall 23 under pressure, enabling the latching part 243 to exit from the groove 312, thus allowing the fiber optic connector 1 to exit from the positioning slot 31. When the locking member 24 loses pressure, its own elasticity causes the latching part 243 to engage within the groove 312, thereby locking the fiber optic connector 1 within the positioning slot 31.

[0032] Preferably, the shape of the groove 312 is configured to match the shape of the snap-fit ​​part 243, so that the snap-fit ​​part 243 can be tightly snapped into the groove 312, ensuring a tight connection between the fiber optic connector 1 and the positioning groove 31.

[0033] Furthermore, such as Figure 3 As shown, the positioning slot 31 has a slot 311 on the edge of the insertion port. A groove 312 is formed at the bottom of the slot 311, and a portion of the horizontal extension 242 is configured to be inserted into the slot 311. Preferably, the shape of the slot 311 is configured to be the same as the shape of the portion of the horizontal extension 242 inserted into the positioning slot 31, which serves to limit the fiber optic connector 1, ensuring that the positions of different fiber optic connectors 1 in the positioning slot 31 are always consistent, and maintaining stable transmission between the fiber optic array and the optical communication module even after replacement.

[0034] To further improve the tight connection between the fiber optic connector 1 and the positioning slot 31, such as Figure 1 and Figure 2 As shown, the fixing spring 4 includes a support section 41 and a spring segment 42. The support section 41 is disposed above the positioning groove 31. The spring segment 42 extends downward from the portion of the support section 41 above the positioning groove 31 toward the positioning groove 31 and bends along the insertion direction of the optical fiber connector 1. The spring segment 42 is configured to press against the optical fiber connector 1 inserted into the positioning groove 31. The spring segment 42's own elastic locking member 24 locks the optical fiber connector 1 within the positioning groove 31.

[0035] like Figure 3As shown, the positioning groove 31 has multiple positioning posts 313 arranged along the insertion direction of the optical fiber connector 1. A guide groove 11 is formed at the bottom of the optical fiber connector 1 along its length. When the optical fiber connector 1 is inserted into the positioning groove 31, the positioning posts 313 abut against the guide groove 11. Preferably, the diameter of the positioning posts 313 is equal to the width of the guide groove 11, ensuring that the direction of insertion of the optical fiber connector 1 into the positioning groove 31 remains consistent and does not shift. Furthermore, the width of the positioning groove 31 is equal to the width of the optical fiber connector 1, further ensuring the direction of movement of the optical fiber connector 1 when inserted along the positioning groove 31. Therefore, after the optical fiber connector 1 is inserted, the optical fiber 5 and the optical communication module can be precisely aligned, ensuring stable transmission between the optical fiber 5 and the optical communication module. In addition, a guide strip 231 is also provided on the lower wall 23 of the fixing buckle 2, allowing the guide groove 11 on the optical fiber connector 1 to be inserted into the fixing buckle 2 along the guide strip 231. Preferably, the width of the guide strip 231 is equal to the width of the guide groove 11, which can ensure the accurate connection between the fixing buckle 2 and the optical fiber connector 1.

[0036] In summary, this pluggable fiber optic connector achieves locking and unlocking between the fiber optic connector 1 and the positioning groove 311 by engaging the locking part 243 on the locking member 24 with the groove 312 in the positioning slot 31. The locking member 24 also has a certain degree of elasticity, allowing the locking part 243 to exit from the groove 312. This allows for the locking and unlocking of the fiber optic connector 1 and the positioning groove 31. Therefore, when a fiber optic cable 5 is damaged, the fiber optic connector 1 can be removed from the positioning base plate 3 for replacement. The locking member 24, in conjunction with the fixing spring 4, ensures that the fiber optic connector 1 is more stably fixed in the positioning groove 31. Furthermore, a positioning post 313 is provided in the positioning groove 31, and a guide groove 11 is provided at the bottom of the fiber optic connector 1, ensuring that the insertion direction of the fiber optic connector 1 remains consistent. This allows for precise alignment of the fiber optic cable 5 and the optical communication module, guaranteeing optical signal transmission.
