Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber communication, in particular to an optical fiber connector and an optical fiber connection structure. Background Art

[0002] In optical fiber communications, optical fiber connectors are often used to connect to optical fiber adapters on a distribution frame to achieve optical fiber transmission. Existing optical fiber connectors are generally connected to optical fiber adapters through a press-type structure.

[0003] CN221225081U discloses a fiber optic connector. A cable is connected to one end of the main shell, and a press buckle is provided on the upper pivot of the main shell. When the fiber optic connector needs to be unplugged, it is only necessary to press the upward-curved tail end of the press buckle to release the connection with the fiber optic adapter. The upward-curved tail end is also provided with a protrusion for easy finger gripping.

[0004] However, during the production of fiber optic connectors, due to the large number of connectors, the upward protrusion of the buckle leads to a large gap between the buckle and the main housing. This allows cables to easily slip between the buckle and the main housing, causing different cables to become tangled. Workers need to carefully separate each cable, and rough movements can damage the optical fibers. At the construction site, fiber optic connectors need to be inserted into equipment one by one. The raised protrusion of the buckle can easily snag on other cables, causing them to become tangled and requiring them to be separated one by one. This increases the workload for operators and reduces work efficiency.

[0005] In addition, when the optical fiber connector is connected to the optical fiber adapter, only a small portion of the buckle is exposed, and fingernails are required to press the exposed portion, which is not very convenient to use. Utility Model Content

[0006] The technical problem to be solved by the present invention is to provide an optical fiber connector and an optical fiber connection structure to solve the above-mentioned problems.

[0007] In order to solve the above technical problems, the technical solutions provided by the present invention are as follows:

[0008] A fiber optic connector includes a fiber optic connector head, one end of which is connected to a tail sleeve, and an elastic buckle is provided on the fiber optic connector head. The elastic buckle includes a connecting portion connected to the fiber optic connector head, a buckle portion extending upward and obliquely from the connecting portion to one side of the tail sleeve, and a pressing portion located at the free end of the buckle portion, wherein the pressing portion is inclined downward from the position connected to the buckle portion to one side of the tail sleeve and extends to the top of the tail sleeve.

[0009] In a preferred embodiment, the end of the optical fiber connector connected to the tail sleeve is also connected to a cable, and the cable passes through the tail sleeve.

[0010] In a preferred embodiment, the distance between the pressing portion and the tail sleeve is smaller than the diameter of the cable.

[0011] In a preferred embodiment, the width of the pressing portion is greater than the width of the buckle portion.

[0012] In a preferred embodiment, the thickness of the pressing portion is smaller than the thickness of the buckle portion.

[0013] In a preferred embodiment, buckle protrusions are provided on both sides of the buckle portion.

[0014] A fiber optic connection structure includes the fiber optic connector and the fiber optic adapter. The fiber optic connector head of the fiber optic connector is installed in the fiber optic adapter. The buckle part is engaged with the fiber optic adapter, and the pressing part is exposed outside the fiber optic adapter.

[0015] In a preferred embodiment, a groove is provided on the housing of the optical fiber adapter on one side close to the elastic pressing buckle, and the buckle protrusion is engaged with the inner wall of the groove.

[0016] Compared with the prior art, the optical fiber connector and optical fiber connection structure of this embodiment have the following advantages:

[0017] 1) The pressing portion of the optical fiber connector extends downward from the position where it connects with the buckle portion toward the side of the tail sleeve, preventing the pressing portion of the elastic buckle from tilting upward and catching the cable, making it more convenient to use;

[0018] 2) In the optical fiber connection structure, the pressing part extends to the top of the tail sleeve, which makes it easier to expose the pressing part outside the optical fiber adapter. This increases the usable space of the pressing part and makes the width of the pressing part wider, increasing the contact area when pressing and making the pressing feel more comfortable.

[0019] 3) The distance between the pressing part and the tail sleeve of the optical fiber connector is smaller than the diameter of the cable. When producing optical fiber connectors, it can prevent the cable from squeezing into the space between the pressing part and the tail sleeve, causing different optical fiber connectors to be entangled together, making production more convenient.

[0025] The following further describes the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "inside", "outside", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the mechanism or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0027] In this embodiment, the direction of the optical fiber connector 1 toward the elastic buckle 4 is defined as the upward direction.

[0028] like Figure 1 As shown, the optical fiber connector of this embodiment includes an optical fiber connector 1, one end of which is connected to a tail sleeve 3. The end of the optical fiber connector 1 connected to the tail sleeve 3 is also connected to a cable 2, and the cable 2 passes through the tail sleeve 3. The optical fiber connector 1 is provided with an elastic buckle 4, which includes a connecting portion 41 connected to the optical fiber connector 1, a buckle portion 43 extending upward and obliquely from the connecting portion 41 toward the side of the tail sleeve 3, and a pressing portion 42 located at the free end of the buckle portion 43. The pressing portion 42 is inclined downward toward the side of the tail sleeve 3 from the position where it is connected to the buckle portion 43 and extends above the tail sleeve 3.

[0029] In this embodiment, the distance between the pressing portion 42 and the tail sleeve 3 is smaller than the diameter of the cable 2 , which can prevent the cable 2 from being squeezed between the pressing portion 42 and the tail sleeve 3 , making it safer and more reliable to use.

[0030] like Figure 1 As shown, the width of the pressing portion 42 is greater than the width of the buckle portion 43, which increases the contact area when pressing and makes the pressing feel more comfortable.

[0031] like Figure 1 As shown, the thickness of the pressing portion 42 is smaller than the thickness of the buckle portion 43 , which facilitates the deformation of the pressing portion 43 .

[0032] like Figure 1As shown, buckle protrusions 431 are provided on both sides of the buckle portion 43 for engaging with the optical fiber adapter.

[0033] The optical fiber connection structure of this embodiment is as follows Figure 2 As shown, it includes the above-mentioned optical fiber connector and optical fiber adapter 5.

[0034] like Figure 3 As shown, a groove 51 is provided on the upper shell of the optical fiber adapter 5 close to the elastic pressing buckle 4.

[0035] like Figure 4 As shown, the optical fiber connector 1 of the optical fiber connector is installed in the optical fiber adapter 5. The buckle protrusion 431 is located inside the groove 51, and the buckle part 43 is engaged with the optical fiber adapter 5 to achieve the connection and positioning of the optical fiber connector and the optical fiber adapter.

[0036] The pressing portion 42 is exposed outside the optical fiber adapter 5. When the optical fiber connector needs to be pulled out, the pressing portion 42 is pressed downward to make the buckle protrusion 431 drop out of the groove 51, and the optical fiber connector can be pulled out.

[0037] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments.
