[0035] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of this application, including various details to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] This application provides a bushing structure for an optical fiber connector.

[0038] like Figures 1 to 6 As shown, the bushing structure 10 includes a first bushing lobe 11 and a second bushing lobe 12. The first bushing lobe 11 is provided with a first positioning structure 13, which is used to fix the terminal 20 of the fiber optic connector. The second bushing lobe 12 is also provided with a second positioning structure 14. The second bushing lobe 12 is provided with a third positioning structure 15 that is adapted to the second positioning structure 14.

[0039] In this configuration, one of the second positioning structure 14 and the third positioning structure 15 can slide relative to the other, so that the first bushing flap 11 and the second bushing flap 12 can be connected or separated; when the first bushing flap 11 and the second bushing flap 12 are connected, the first bushing flap 11 and the second bushing flap 12 enclose each other to form a bushing.

[0040] The first bushing petal 11 and the second bushing petal 12 can be approximately semi-cylindrical structures, which together form an approximately cylindrical bushing when connected (or mated).

[0041] In addition to the bushing, the fiber optic connector also includes an outer sleeve 30, terminals 20 (such as LC terminals 20), and a tail crimp sleeve 40 (hereinafter referred to as the tail sleeve). The terminals 20 are equipped with clips 23, and are fixed within and extend out of the bushing. The outer sleeve 30 and the tail crimp sleeve 40 are respectively connected to both ends of the bushing. The fiber optic connector's cable bundle is located inside the bushing. The bushing is used to secure the terminals 20 and protect the cable bundle.

[0042] The bushing structure 10 of this application embodiment is mainly applied to the plug end of the fiber optic connector.

[0043] The sidewall of terminal 20 may be provided with a first sliding groove 21, so that the first positioning structure 13 may include a first slider 131 adapted to the first sliding groove 21. The sidewall of terminal 20 may also be provided with a second slider 22, so that the first positioning structure 13 may include a second sliding groove 132 adapted to the second slider 22.

[0044] One of the second positioning structure 14 and the third positioning structure 15 can slide relative to the other. For example, the second positioning structure 14 can slide relative to the third positioning structure 15, or the third positioning structure 15 can slide relative to the second positioning structure 14.

[0045] In this embodiment, by providing a second positioning structure 14 on the first bushing lobe 11 and a third positioning structure 15 adapted to the second bushing lobe 12, one of the second positioning structure 14 and the third positioning structure 15 can slide relative to the other, enabling the first bushing lobe 11 and the second bushing lobe 12 to be quickly and conveniently connected or separated. Thus, when the terminal 20 fails, the faulty terminal 20 can be quickly and conveniently replaced simply by separating the first bushing lobe 11 and the second bushing lobe 12, without having to replace the fiber optic connector again, which can reduce the cost of using the fiber optic connector.

[0046] In some embodiments, the second positioning structure 14 includes an inclined block 141 disposed on the side of the first bushing flap 11;

[0047] The third positioning structure 15 includes a slanted groove (or slanted opening) 151 provided on the side of the second bushing flap 12;

[0048] The inclined block 141 can slide along the inclined groove (or inclined opening) 151.

[0049] By setting the second positioning structure 14 as a wedge block 141 and the third positioning structure 15 as a groove (or opening) 151, the wedge block 141 can be pushed into the groove (or opening) 151 along the groove. After the wedge block 141 is fully pushed into the groove (or opening) 151, the first bushing lobe 11 and the second bushing lobe 12 are connected. At this time, if it is necessary to separate the first bushing lobe 11 and the second bushing lobe 12, a downward (or obliquely downward) force needs to be applied to the first bushing lobe 11, and / or an upward (or obliquely downward) force needs to be applied to the second bushing lobe 12.

[0050] It should be noted that the second positioning structure 14 may also be a slanted groove (or slanted opening) 151 provided on the side of the first bushing 11, while the third positioning structure 15 may be a slanted block 141 provided on the side of the second bushing 12. This application embodiment does not limit this.

[0051] By adopting the second positioning structure 14 and the third positioning structure 15 described above, the connection and separation of the first bushing 11 and the second bushing 12 can be realized quickly and conveniently, and the easy separation of the first bushing 11 and the second bushing 12 can be avoided, thereby ensuring the connection stability of the first bushing 11 and the second bushing 12.

[0052] It should also be noted that, in the embodiments of this application, the second positioning structure 14 and the third positioning structure 15 can also adopt other positioning structures.

[0053] In some embodiments, the first bushing flap 11 includes a first end and a second end, the first end of the first bushing flap 11 is the end from which the terminal 20 extends, and the second end of the first bushing flap 11 is the end for connecting the tail crimp sleeve 40.

[0054] The second positioning structure 14 is located near the first end of the first bushing flap 11.

[0055] The second positioning structure 14 is located near the first end of the first bushing flap 11, which can be understood as the second positioning structure 14 being near or located in the area of ​​the fixed terminal 20. This makes it easier to operate the first bushing flap 11 and the second bushing flap 12 when the terminal 20 needs to be replaced, and is more in line with the user's operating habits.

[0056] In some embodiments, the second end of the first bushing flap 11 is formed with a closed annular portion 111, which is used to connect with the tail crimp sleeve 40.

[0057] When the inclined block 141 slides into the inclined groove or inclined opening, the second bushing 12 comes into contact with the annular portion 111.

[0058] In this embodiment, the closed annular portion 111 is formed at the second end of the first bushing lobe 11, which can improve the overall structure of the structure and thus improve the structural strength of the entire bushing, making the connection strength between the bushing and the tail pressure sleeve 40 higher.

[0059] When the inclined block 141 slides into the inclined groove or inclined opening, the second bushing lobe 12 comes into contact with the annular portion 111, which indicates that the first bushing lobe 11 and the second bushing lobe 12 are well connected.

[0060] In some embodiments, the area of ​​the first bushing lobe 11 adjacent to the annular portion 111 is further provided with a positioning notch 112;

[0061] The second bushing flap 12 is also provided with a positioning block 121 that is adapted to the positioning notch 112;

[0062] When the inclined block 141 slides into the inclined groove or inclined opening, the positioning block 121 engages with the positioning notch 112.

[0063] In this embodiment, by providing a positioning notch 112 in the region adjacent to the annular portion 111 of the first bushing lobe 11, and providing a positioning block 121 adapted to the positioning notch 112 in the second bushing lobe 12, multiple positioning of the first bushing lobe 11 and the second bushing lobe 12 can be achieved. That is, in addition to positioning by the second positioning structure 14 and the third positioning structure 15, positioning is also achieved by the positioning notch 112 and the positioning hole. In this way, the connection stability between the first bushing lobe 11 and the second bushing lobe 12 can be further improved.

[0064] In some embodiments, the inner wall of the second bushing flap 12 is further provided with a pre-tightening buckle 122;

[0065] When the inclined block 141 slides into the inclined groove or inclined opening, the pre-tightening buckle 122 contacts the inner wall of the annular part 111.

[0066] Specifically, the end of the pre-tightening buckle 122 slightly extends beyond the edge of the second bushing 12, and the end face of the pre-tightening buckle 122 has a certain curvature to form a guide ring 111 that passes over the guide surface of the pre-tightening buckle 122. When the first bushing 11 and the second bushing 12 are connected, the ring 111 of the first bushing 11 passes over the pre-tightening buckle 122, and the pre-tightening buckle 122 contacts the inner wall of the ring 111. In this way, the pre-tightening buckle 122 restricts the first bushing 11 from the inside, which can prevent the second bushing 12 from separating from the first bushing 11.

[0067] In some embodiments, the second bushing 12 is further provided with a slot 123 for the clip 23 of the terminal 20 to extend out.

[0068] In this way, when the first bushing flap 11 is connected to the second bushing flap 12, the clip 23 of the terminal 20 can extend out of the bushing via a snap to provide sufficient space for the clip 23 of the terminal 20 to move.

[0069] In some embodiments, the first bushing flap 11 and / or the second bushing flap 12 are further provided with a protrusion 16, which is used to engage with the slot 31 of the outer shell 30 of the fiber optic connector.

[0070] By providing protrusions 16 on the first bushing flap 11 and / or the second bushing flap 12, it is beneficial to improve the connection stability between the bushing and the outer sleeve 30.

[0071] like Figures 1 to 6 As shown in the figure, this application embodiment also provides an optical fiber connector, including a bushing, wherein the bushing adopts any of the bushing structures 10 in the bushing structure embodiment.

[0072] Any of the embodiments described above in the bushing structure embodiment can be applied to the fiber optic connector embodiment and can achieve the same beneficial effects. To avoid repetition, they will not be described in detail here.

[0073] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
