[0002] A fiber optic adapter is a device that can be used to connect fiber optic connectors of different types or different interface standards. A fiber optic adapter connects fiber optic connectors through the ports at both ends to achieve the transmission of optical signals. A fiber optic adapter ensures seamless transmission of optical signals by aligning the optical fibers of two independent optical cables.

[0003] There are many types of fiber optic adapters, such as LC, SC, FC, ST, etc. Fiber optic adapters are generally equipped with detachable plugs at both ends, especially SC-type fiber optic adapters, which can prevent dust from entering the fiber optic adapter.

[0037] See also Figures 1 to 5 The present invention proposes an optical fiber adapter 100, comprising a shell 10, a connecting sleeve 20, a shielding door 30 and a reset member 40, wherein the shell 10 is provided with a first port 13 and a second port 16 on opposite sides; the connecting sleeve 20 is arranged in the shell 10, and the two ends of the connecting sleeve 20 are respectively facing the first port 13 and the second port 16, and the connecting sleeve 20 is used to connect two optical fiber connectors; the shielding door 30 is movably connected to the wall surface of the first port 13, and the shielding door 30 has an open state and a closed state. When the shielding door 30 is in the closed state, the shielding door 30 blocks the first port 13, and when the shielding door 30 is in the closed state, the first port 13 is exposed; one end of the reset member 40 is installed on the shell 10, and the other end is connected to the shielding door 30, so that the shielding door 30 has a tendency to close.

[0038] The technical solution of the present invention uses a shielding door 30 to shield the first port 13. The shielding door 30 has a tendency to close under the action of the reset member 40. Therefore, when there is no external force, the shielding door 30 is always in a closed state. On the one hand, it can effectively prevent the high-intensity infrared light beam from leaking out and causing damage to the human eye. On the other hand, it can effectively prevent dust from entering the inside of the adapter, ensuring the stability of light transmission after the optical fiber is connected. In addition, when docking the optical fiber connector to the first port 13, the optical fiber connector can be directly pushed against the shielding door 30 and inserted into the first port 13. During this process, the first port 13 is always blocked, which can also prevent the infrared light beam from leaking out. In this way, the operator does not need to wear protective gear during the docking process, which greatly improves the convenience of assembly.

[0039] The connecting sleeve 20 plays the role of aligning the optical fiber in the optical fiber adapter 100, and is generally made of ceramic material, which has good thermal stability, high hardness, high melting point and wear resistance. The second port 16 of the optical fiber adapter 100 and its internal structure can be symmetrically arranged with the first port 13, and a plug 60 can also be used.

[0040] There are many ways to specifically install the shielding door 30 on the housing 10. In some embodiments of the present invention, the housing 10 is provided with a sliding hole on one side wall of the first port 13, and the shielding door 30 is slidably installed in the sliding hole. The reset member 40 is a reset spring. Under the action of the reset spring, the shielding door 30 slides to cover the first port 13. When the optical fiber connector is docked to the first port 13, the shielding door 30 can be pulled open and the docking operation can be performed. Furthermore, the outer side surface of the shielding door 30 can be provided with a guiding inclined surface, so that the optical fiber connector can be directly pressed against the guiding inclined surface, and the shielding door 30 is pressed to slide open, which is convenient for assembly.

[0041] In order to improve the light-shielding and dust-proof performance of the shielding door 30, in some embodiments of the present invention, one side of the shielding door 30 is rotatably connected to a side wall of the first port 13, and a stop step 151 is provided on the wall of the first port 13. When the shielding door 30 is in a closed state, the peripheral edge of the outer side surface of the shielding door 30 abuts against the stop step 151. In this way, the shielding door 30 fits against the stop step 151, and multiple gaps are formed between the shielding door 30 and the wall of the first port 13, thereby effectively preventing light from leaking out through the gap between the shielding door 30 and the inner wall of the housing 10, and dust is less likely to enter the housing 10.

[0042] In order to further facilitate the docking of the optical fiber connector, in some embodiments of the present invention, the stop step 151 is extended obliquely, so that the shielding door 30 is inclined in a direction away from its own rotation axis toward the connecting sleeve 20 in a closed state. In this way, when inserting the optical fiber connector into the first port 13, the operator's thrust stroke can be reduced, thereby facilitating docking.

[0043] There are many specific implementations of the above-mentioned limiting step. For example, the limiting step can be a convex rib provided on the inner wall of the housing 10. Preferably, in some embodiments of the present invention, the housing 10 is provided with a receiving groove 15 on both side walls in the direction of the rotation axis of the shielding door 30, and the stop step 151 is a side groove wall of the receiving groove 15 close to the first port 13, and the two side edges of the shielding door 30 are rotatably received in the two receiving grooves 15. In this way, the overall structure of the optical fiber adapter 100 is more compact, and the shielding door 30 can be effectively limited in the receiving groove 15, and the structural stability is higher.

[0044] Furthermore, in some embodiments of the present invention, the receiving groove 15 is configured to be fan-shaped, so that the receiving groove 15 is more compatible with the shielding door 30 .

[0045] The housing 10 of the optical fiber adapter 100 is generally configured as a split structure, specifically, it can be divided into two, three or more detachable parts, so that it is convenient to assemble and fix the shielding door 30. Preferably, in some embodiments of the present invention, the housing 10 includes a housing body 11 and a base 12, the housing body 11 is formed with the first port 13, and the connecting sleeve 20 is installed in the housing body 11; the housing body 11 is provided with an installation opening 111 on a wall between the connecting sleeve 20 and the first port 13, and the walls on the opposite sides of the installation opening 111 are respectively provided with assembly notches 141, and the opposite sides of the shielding door 30 are provided with convex shafts 31, and the convex shafts 31 are rotatably assembled in the corresponding assembly notches 141, and the base 12 is installed in the installation opening 111 and limits the convex shaft 31 in the assembly notches 141. According to this solution, when the shielding door 30 is assembled to the housing 10, the convex shaft 31 of the shielding door 30 can be pre-assembled in the assembly notch 141, and finally the base 12 can be covered in the installation opening 111, which is convenient for assembly and has good overall structural stability after assembly.

[0046] In addition to being a compression spring, the reset member 40 may also be a torsion spring, a metal spring, etc. Preferably, in some embodiments of the present invention, the reset member 40 is a reset spring, and the reset spring includes a connection end 411 and a top end 412 that are arranged opposite to each other, the connection end 411 is clamped between the base 12 and the wall surface of the installation opening 111, and the top end 412 abuts against an end of the shielding door 30 away from the convex shaft 31. In this way, when the shielding door 30 is in an open state, the reset spring is squeezed between the shielding door 30 and the base 12, which occupies less space in the housing 10, which is conducive to the overall miniaturization of the optical fiber adapter 100. Moreover, after the optical fiber connector is pulled out from the first port 13, the reset spring can respond quickly to reset the shielding door 30 to prevent light leakage.

[0047] In the above-mentioned shell 10 structure, the shell body 11 and the base 12 can be made of the same material or different materials. Generally, the shell body 11 and the base 12 are made of plastic material, such as PBT plastic, which is durable and has a long service life. PP plastic, ABS plastic, etc. can also be used, which is not limited here.

[0048] There are many ways to install the base 12 on the shell body 11. In some embodiments of the present invention, the base 12 is provided with clamping arms 124 on both sides perpendicular to the axial direction of the connecting sleeve 20, and the clamping arms 124 on both sides are clamped and connected to the opposite sides of the shell body 11 respectively.

[0049] Furthermore, an escape recess 123 is formed on the inner wall surface of the base 12, and when the shielding door 30 is in an open state, the shielding door 30 is stored in the escape recess 123. With such a configuration, the fiber optic adapter 100 is more compact as a whole.

[0050] See also Figure 6 In some embodiments of the present invention, a side wall of the installation opening 111 close to the first port 13 is set as an assembly step 112, and the assembly step 112 includes an angled plug-in surface 1122 and a cover pressure surface 1121, and the plug-in surface 1122 is provided with a plug-in groove 1123, and the groove of the plug-in groove 1123 is arranged in the opposite direction to the opening direction of the first port 13; a first plug-in flange 4111 is provided on the edge of the connecting end 411, and a second plug-in flange 121 is provided on one side of the base 12. During assembly, the first plug-in flange 4111 and the second plug-in flange 121 are both inserted into the plug-in groove 1123, so that the connecting end 411 is clamped between the base 12 and the cover pressure surface 1121, and the assembly is convenient and the structural stability is good.

[0051] In some embodiments of the present invention, the cover pressing surface 1121 is provided with a limiting protrusion 1124, the connecting end 411 is provided with a first limiting hole 4112, the base 12 is provided with a second limiting hole 122 aligned with the first limiting hole 4112, and the limiting protrusion 1124 is clamped in the first limiting hole 4112 and the second limiting hole 122. In this way, the stability of the reset spring and the base 12 connected to the shell body 11 can be further improved.

[0052] The above reset spring is generally made of metal, which has high strength, long service life and wear resistance; of course, it can also be made of plastic material, which can be set according to specific circumstances and is not limited here.

[0053] In some embodiments of the present invention, the optical fiber adapter 100 further includes a buckle structure 50, which is connected to the housing 10 and is used to buckle the optical fiber connector docked to the connecting sleeve 20. The main function of the buckle structure 50 is to buckle the optical fiber connector docked to the connecting sleeve 20, ensure that the optical fiber connector is fixed in the adapter, and ensure the stability of optical signal transmission.

[0054] There are many specific implementations of the snap-fit ​​structure 50. In some embodiments of the present invention, the snap-fit ​​structure 50 includes a protective sleeve, which is arranged outside the connecting sleeve 20. The end face of the protective sleeve facing the first port 13 is provided with an annular groove for the external optical fiber connector to be snapped in.

[0055] Preferably, in some embodiments of the present invention, the snap-fit ​​structure 50 includes a base plate 51, a protective sleeve 52 and at least two snap-fit ​​arms 53, the base plate 51 is connected to the housing 10, the base plate 51 is provided with an avoidance hole for the connecting sleeve 20 to pass through, one end of the protective sleeve 52 is connected to a side of the base plate 51 facing the first port 13, and is nested outside the connecting sleeve 20; one end of at least two of the snap-fit ​​arms 53 is connected to a side of the base plate 51 facing the first port 13, and is spaced around the outer circumference of the protective sleeve 52. The above scheme can protect the connecting sleeve 20 through the protective sleeve 52 to prevent the connecting sleeve 20 from being worn and damaged, and can be fixed to the housing 10 by means of threaded connection, clamping, etc. through the base plate 51. In some embodiments of the present invention, the base plate 51 and the housing 10 are integrally formed, and the overall structure is relatively stable, which is conducive to simplifying the assembly process and can effectively prevent assembly errors from affecting the stability of the connecting sleeve 20. At least two clamping arms 53 can be clamped on the peripheral side of the optical fiber connector, and the optical fiber connector is balanced in force, and the overall structure is stable after docking. The number of the clamping arms 53 can be set to two, or it can be set to three, four or more. The clamping arms 53 with arc-shaped cross-sections can be used to match the shape of the end of the optical fiber connector.

[0056] In some embodiments of the present invention, the optical fiber adapter 100 further includes a leaf spring 70 , which is mounted on the outer wall of the housing 10 for being snap-fitted and fixed to an external device.

[0057] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
