[0025] In the various embodiments of this application, for ease of description and not limitation, the term "connection" used in the patent application specification and claims is not limited to physical or mechanical connections, whether direct or indirect. Terms such as "upper," "lower," "above," "below," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0026] Please see Figures 1 to 2 This application provides an optical fiber connection assembly 100, which includes an adapter 200 and a connector 300, and the adapter 200 and the connector 300 are interconnected. Figure 1This is a schematic diagram of the structure of the fiber optic connection assembly 100 formed by the mutual insertion and assembly of the adapter 200 and the connector 300. Figure 2 This is a schematic diagram showing the structure where the adapter 200 and connector 300 are separated.

[0027] Please refer to the following: Figure 3 The adapter 200 includes a housing 21 and an elastic element 23, the elastic element 23 being fixed to the housing 21.

[0028] Please refer to the following: Figure 4 The housing 21 includes a first surface 21a and a second surface 21b spaced apart and opposite to each other in a first direction X, and a first receiving groove 211 and a second receiving groove 213 are formed on the housing 21. The first receiving groove 211 extends through the first surface 21a and the second surface 21b along the first direction X, and is used to receive a connector. The second receiving groove 213 is recessed from the first surface 21a towards the second surface 21b along the first direction X, and the second receiving groove 213 is spaced apart from the first receiving groove 211 along a second direction Y, which is perpendicular to the first direction X. In this embodiment, the second receiving groove 213 may further extend through the second surface 21b.

[0029] One end of the elastic member 23 is embedded and fixed in the second receiving groove 213, and the other end is located in the first receiving groove 211, for supporting the connector subsequently inserted into the first receiving groove 211. In this embodiment, the two ends of the elastic member 23 are respectively embedded from the opening of the first receiving groove 211 on the first surface 21a and the opening of the second receiving groove 213 on the first surface 21a, and the connecting portion of the elastic member 23 connecting the two ends can protrude from the first surface 21a in a direction away from the second surface 21b.

[0030] In this embodiment, the elastic element 23 can be a generally U-shaped spring sheet, and the material can be steel. In some embodiments, the shape of the elastic element 23 is not limited to U-shape, and can also be regular or irregular shapes such as V-shape or W-shape; the material of the elastic element 23 is not limited to steel sheet, and can also be other materials such as plastic or alloy. It is only necessary to ensure that after the elastic element 23 is fixed to the outer shell 21, the end of the elastic element 23 located in the first receiving groove 211 can be displaced in the second direction Y under force.

[0031] The length of the portion of the elastic element 23 located in the second receiving groove 213 in the first direction X can be greater than the length of the portion of the elastic element 23 located in the first receiving groove 211 in the first direction X. This improves the stability of the elastic element 23 during use and reduces the risk of loosening or falling off. In this embodiment, the elastic element 23 can be fixed in the second receiving groove 213 by adhesive. In some embodiments, the elastic element 23 can also be fixed in the second receiving groove 213 by interference fit, snap-fit, or other methods.

[0032] The inner wall of the first receiving groove 211 is provided with a guide portion 212 extending along the first direction X. The guide portion 212 extends from the connection between the inner wall of the first receiving groove 211 and the first surface 21a toward the second surface 21b, and is used to position and guide the subsequently inserted connector. In this embodiment, the guide portion 212 may be a protrusion and may be provided on the inner wall of the first receiving groove 211 away from the second receiving groove 213. The cross-section of the protrusion perpendicular to the first direction X may be triangular. In some embodiments, the cross-section of the protrusion perpendicular to the first direction X is not limited to the above shape, and may also be rectangular, trapezoidal, semi-circular, semi-elliptical, or other shapes. In some embodiments, the guide portion 212 may also be a strip groove. Similarly, the cross-section of the strip groove perpendicular to the first direction X may be, but is not limited to, triangular, rectangular, trapezoidal, semi-circular, or semi-elliptical shapes. The guide portion 212 may also be provided on other inner walls of the first receiving groove 211.

[0033] Please refer to the following: Figure 5 The outer casing 21 may also have a connecting hole 214. The connecting hole 214 penetrates the outer casing 21 along the second direction Y and communicates with the first receiving groove 211, and is located on the side of the first receiving groove 211 opposite to the second receiving groove 213 and corresponds to the elastic member 23. The connecting hole 214 is used to pass through an operating member (not shown) to act on the elastic member 23, causing the end of the elastic member 23 located in the first receiving groove 211 to displace in the second direction Y, thereby facilitating the removal of the connector inserted into the first receiving groove 211. In this embodiment, the connecting hole 214 corresponds to the end of the elastic member 23 located in the first receiving groove 211, thereby facilitating the deformation of the elastic member 23 with a smaller force.

[0034] The second surface 21b of the housing 21 may also be provided with a plug-in terminal 25 protruding in the direction away from the first surface 21a, so as to facilitate positioning and plugging when the adapter 200 is connected to other adapters, thereby facilitating high-precision docking.

[0035] Please see Figure 1 and Figure 2 The connector 300 includes a housing 31 and a plurality of optical fibers 33. Each optical fiber 33 is partially housed in the housing 31.

[0036] Please refer to the following: Figure 6 and Figure 7 The outer surface of the housing 31 may be provided with a recess 310, which is used to abut against the end of the elastic member 23 located in the first receiving groove 211 of the adapter 200 when it is inserted into the first receiving groove 211 of the adapter 200, so as to limit and fix the connector 300 and the adapter 200.

[0037] The housing 31 has a plurality of wire holes 32, each wire hole 32 penetrating through a first end face 31a and a second end face 31b opposite to each other on the housing 31, and an optical fiber 33 is inserted into the wire hole 32. The outer surface of the housing 31 also includes a first connecting surface 31c and a second connecting surface 31d located between the first end face 31a and the second end face 31b, with the first connecting surface 31c and the second connecting surface 31d opposite to each other. Each wire hole 32 is located between the first connecting surface 31c and the second connecting surface 31d.

[0038] In this embodiment, the recess 310 is formed by recessing inward from the first connecting surface 31c. In this embodiment, the recess 310 may be wedge-shaped, including an inclined surface 311 and a supporting surface 313. The inclined surface 311 is inclined inward from the first connecting surface 31c toward the first end face 31a, and the supporting surface 313 connects the first connecting surface 31d and the end of the inclined surface 311 near the first end face 31a. In some embodiments, the recess 310 is not limited to the structure described above.

[0039] The outer surface of the housing 31 may be provided with a guide member 35 for cooperating with the guide portion 212. The extension direction of the guide member 35 is parallel to the penetration direction of the wire hole 32. Specifically, in this embodiment, the guide member 35 may be formed on the second connecting surface 31d and extends from the connection point between the second connecting surface 31d and the first end surface 31a in a direction parallel to the penetration direction of the wire hole 32. The guide member 35 may be a strip groove, and the cross-section of the strip groove in the direction perpendicular to the penetration direction of the wire hole 32 may be, but is not limited to, triangular, rectangular, trapezoidal, semi-circular, or semi-elliptical shapes. In some embodiments, the guide member 35 may also be a convex strip, and the cross-section of the convex strip in the direction perpendicular to the penetration direction of the wire hole 32 may be, but is not limited to, triangular, rectangular, trapezoidal, semi-circular, or semi-elliptical shapes. It is understood that when the guide member 35 is a strip groove, the guide portion 212 is a matching convex strip; when the guide member 35 is a convex strip, the guide portion 212 is a matching strip groove.

[0040] Please refer to the following: Figure 8 When the connector 300 is inserted into the adapter 200, the guide 35 and the guide portion 212 are engaged to achieve precise alignment, thereby inserting one end of the housing 31 into the outer shell 21. As the housing 31 further enters the outer shell 21, the housing 31 compresses the elastic member 23 until the end of the elastic member 23 located in the first receiving groove 211 is located in the recess 310. At this time, the end of the elastic member 23 located in the first receiving groove 211 and the recess 310 are mutually engaged, thereby fixing the connector 300 and the adapter 200.

[0041] When it is necessary to disassemble the connector 300 and the adapter 200, by pressing the elastic member 23, the limiting effect of the end of the elastic member 23 located in the first receiving groove 211 on the recess 310 is released, and the housing 31 is taken out from the outer shell 21, thus realizing the separation of the connector 300 and the adapter 200.

[0042] The adapter 200 and connector 300 provided in this application embodiment have a simple overall structure and good connection performance. The adapter 200 and connector 300 are pluggable and detachable by the mutual locking of the elastic member 23 on the adapter 200 and the recess 310 on the connector 300.

[0043] Furthermore, the cooperation between the guide portion 212 and the guide member 35 enables precise positioning of the connector 300 and adapter 200 during insertion, which helps to further improve connection performance. The insertion terminals 25 on the adapter 300 facilitate positioning and insertion when the adapter 200 is connected to other adapters, enabling high-precision connection while avoiding the loss of optical performance caused by traditional glue fixation.

[0044] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
