[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] In the description of the present invention, it is necessary to understand that the orientations or positional relationships indicated by various orientation terms are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] Some embodiments of the present invention provide a universal interface for an optical power meter, such as Figures 1 to 4As shown, the universal interface 100 of the optical power meter includes an optical power meter interface plate 1 , a pigtail interface dial 2 and a handle 3 .

[0031] like Figure 1 , Figure 2A , Figure 2B and Figure 4 As shown, the optical power meter interface plate 1 has an optical power meter docking screw 11 on its lower surface and a circular shaft 12 on its upper surface. Specifically, the circular shaft 12 protrudes from the upper surface of the optical power meter interface plate 1 and is vertically arranged thereto.

[0032] It can be understood that the optical power meter docking screw 11 is arranged on the lower surface of the optical power meter interface plate 1 and can be docked with the connector on the optical power meter, so that the optical power meter interface plate 1 can be fixed on the optical power meter more firmly. Exemplarily, the optical power meter docking screw 11 can be rotatably docked with the connector on the optical power meter (for example, the connector on the optical power meter is a threaded port, and the optical power meter docking screw 11 is also a threaded port), and can also be docked with the connector buckle on the optical power meter. The utility model does not limit the specific shape of the optical power meter docking screw 11.

[0033] like Figure 3A , Figure 3B and Figure 4 As shown, the pigtail interface dial 2 is arranged above the optical power meter interface disk 1 and is provided with a through hole 21 matching the circular axis 12. Specifically, the through hole 21 is perpendicular to the lower surface of the pigtail interface dial 2, so that the circular axis 12 of the optical power meter interface disk 1 is inserted into the through hole 21 of the pigtail interface dial 2. A plurality of different types of pigtail interfaces 22 are arranged on the upper surface of the pigtail interface dial 2, and each of the plurality of different types of pigtail interfaces 22 is successively connected and docked with the optical power meter docking screw 11 as the pigtail interface dial 2 rotates around the circular axis 12.

[0034] It can be understood that the pigtail interface dial 2 is arranged above the optical power meter interface disk 1, then the lower surface of the pigtail interface dial 2 contacts the upper surface of the optical power meter interface disk 1, the through hole 21 is perpendicular to the lower surface of the pigtail interface dial 2, and the circular shaft 12 is perpendicular to the upper surface of the optical power meter interface disk 1, and the through hole 21 matches the circular shaft 12, so that the circular shaft 12 can be inserted into the through hole 21, and the pigtail interface dial 2 and the optical power meter interface disk 1 can maintain good contact, which is convenient for the interfaces on the two disks to be connected and docked.

[0035] In some embodiments, Figure 3A and Figure 3B As shown, a plurality of different types of pigtail interfaces 22 include an FC pigtail interface 221 , an SC pigtail interface 222 , and an LC pigtail interface 223 .

[0036] It is understandable that 2, 3, 4 or even more types of pigtail interfaces can be set on the pigtail interface dial 2. Other types of pigtail interfaces can also be set on the pigtail interface dial 2. The utility model takes the common FC pigtail interface 221, SC pigtail interface 222 and LC pigtail interface 223 as examples, but is not limited thereto.

[0037] Exemplarily, when the pigtail interface dial 2 is rotated to the point where the FC pigtail interface 221 thereon is connected to the optical power meter docking screw 11, the connector on the optical power meter is inserted from the bottom of the optical power meter interface disk 1 into the optical power meter docking screw 11, and the FC pigtail is inserted from the upper surface of the pigtail interface dial 2 into the FC pigtail interface 221, and the FC pigtail is connected to the connector on the optical power meter through the universal interface 100. The use of the SC pigtail interface 222 and the LC pigtail interface 223 is the same as that of the FC pigtail interface 221, and will not be repeated here.

[0038] In some embodiments, the outer diameter of the circular shaft 12 is the same as the inner diameter of the through hole 21 .

[0039] It can be understood that the outer diameter of the circular shaft 12 is the same as the inner diameter of the through hole 21 , the connection between the circular shaft 12 and the through hole 21 is tighter, and the rotation of the pigtail interface dial 2 is more stable.

[0040] In some embodiments, Figure 2A and Figure 3A As shown, the optical power meter interface disk 1 and the pigtail interface disk 2 are both circular disks.

[0041] It can be understood that the optical power meter interface disk 1 and the fiber pigtail interface dial 2 are both circular disks, which means that the upper surface or lower surface of the optical power meter interface disk 1 and the fiber pigtail interface dial 2 is circular, and the optical power meter interface disk 1 and the fiber pigtail interface dial 2 are cylindrical in appearance.

[0042] In some embodiments, Figure 2B and Figure 3B As shown, the optical power meter interface plate 1 and the pigtail interface dial 2 are both square plates.

[0043] It can be understood that, through the cooperation of the through hole 21 and the circular shaft 12, the shape of the optical power meter interface disk 1 and the pigtail interface dial 2 may not be limited to a cylindrical shape, but may also be a disk with a square surface. As long as the positions of the pigtail interfaces on the pigtail interface dial 2 are reasonably set, they can be connected with the optical power meter docking screw 11 on the optical power meter interface disk 1.

[0044] Understandably, for a workpiece that needs to rotate, a circular appearance is more convenient and saves more space. In the following, the embodiment provided by the utility model is described by taking the optical power meter interface disk 1 and the pigtail interface dial 2 as circular disks as an example.

[0045] like Figure 4 As shown, the handle 3 is connected to the pigtail interface dial 2 to drive the pigtail interface dial 2 to rotate around the circular axis 12.

[0046] Exemplarily, the handle 3 may be fixedly connected to the side of the pigtail interface dial 2 , and the user can directly rotate the handle 3 to drive the pigtail interface dial 2 to rotate.

[0047] It is understandable that the handle 3 can also be connected to the pigtail interface dial 2 in other ways, and drive the pigtail interface dial 2 to rotate around the circular axis 12.

[0048] In some embodiments, Figure 5 As shown, the pigtail interface dial 2 is cylindrical and a wavy groove 23 is provided on the outer side of the cylindrical surface along the circumferential direction. The handle 3 is arranged on the side of the pigtail interface dial 2, and a protrusion 31 is provided on the side of the handle 3 close to the pigtail interface dial 2, and the end of the protrusion 31 is embedded in the wavy groove 23. The side of the optical power meter interface disk 1 is provided with a first ear 13 including a through hole, and the lower part of the handle 3 extends downward into the through hole of the first ear 13 on the side of the optical power meter interface disk 1, and moves up and down in the through hole of the first ear 13, so that the protrusion 31 moves along the wavy groove 23, driving the pigtail interface dial 2 to rotate around the circular axis 12.

[0049] It can be understood that since a wavy groove 23 is provided on the outer side of the cylindrical surface of the pigtail interface dial 2, when the handle 3 moves up and down in the through hole of the first ear 13, the protrusion 31 of the handle 3 will move along the wavy groove 23, thereby driving the pigtail interface dial 2 to rotate around the circular axis 12.

[0050] For example, Figure 6 As shown, the outer surface of the first ear 13 is fixedly connected to the side of the optical power meter interface disk 1 (for example, welded), and the first ear 13 is hollow to facilitate the insertion of the handle 3. In this way, the handle 3 can move up and down perpendicular to the pigtail interface dial 2, thereby driving the protrusion 31 to move up and down. Since the protrusion 31 is embedded in the wavy groove 23, under the action of the protrusion 31, the pigtail interface dial 2 will rotate around the circular axis 12, so that each of the multiple different types of pigtail interfaces 22 is connected and docked with the optical power meter docking screw 11 in succession as the pigtail interface dial 2 rotates.

[0051] In some embodiments, Figure 7 As shown, the side of the optical power meter interface plate 1 is also provided with a second ear portion 14, and the second ear portion 14 is arranged directly below the first ear portion 13. The top of the handle 3 is provided with a pressing portion 32, the bottom of the handle 3 is connected to one end of a spring 33, and the other end of the spring 33 is connected to the second ear portion 14 on the side of the optical power meter interface plate 1.

[0052] It can be understood that the area of ​​the upper surface of the pressing portion 32 is larger than the area of ​​the top surface of the handle 3. The upper surface of the pressing portion 32 can increase the contact area between the user and the handle 3. When the user presses the pressing portion 32, the handle 3 moves downward perpendicular to the pigtail interface dial 2, the protrusion 31 also moves downward, and the spring 33 is compressed. When the protrusion 31 reaches the lowest point of the wavy groove 23, the spring 33 can provide the handle 3 with an upward force perpendicular to the pigtail interface dial 2, and push the handle 3 upward, and drive the protrusion 31 to move upward. In this way, the user does not need to provide an additional upward force perpendicular to the pigtail interface dial 2, and the handle 3 can rebound with the help of the elastic force of the spring 33. Therefore, the pressing portion 32 and the spring 33 can increase the convenience of use.

[0053] It can be understood that the height of the handle 3, the thickness of the pigtail interface dial 2 and the length of the spring 33 can be reasonably set according to actual conditions, so that the protrusion 31 can reach any position along the wavy groove 23, for example, the lowest point of the wavy groove 23 and the highest point of the wavy groove 23.

[0054] For example, Figure 8 As shown, the outer surface of the second ear portion 14 is fixedly connected (for example, welded) to the side of the optical power meter interface plate 1. The second ear portion 14 is arranged directly below the first ear portion 13, and the bottom of the second ear portion 14 is solid, that is, the spring 33 cannot penetrate the bottom of the second ear portion 14, so that the spring 33 can provide a rebound force for the handle 3.

[0055] It can be understood that the bottom of the handle 3 can be fixedly connected to one end of the spring 33, and the other end of the spring 33 can also be fixedly connected to the second ear 14 of the optical power meter interface plate 1, thereby increasing the stability of the up and down movement of the handle 3.

[0056] In some embodiments, Fig. 9 As shown, the pressing portion 32 is higher than the upper surface of the pigtail interface dial 2 .

[0057] It can be understood that when the length of the handle 3 (i.e., the dimension of the handle 3 along the direction perpendicular to the pigtail interface dial 2) is greater than the thickness of the pigtail interface dial 2 (the dimension along the direction perpendicular to the pigtail interface dial 2, or called the height), the pressing portion 32 can be higher than the upper surface of the pigtail interface dial 2. In this way, the user is more convenient when using it.

[0058] In some embodiments, Fig.10As shown, a spring slot 34 is provided between the first ear portion 13 and the second ear portion 14, so that the spring 33 can be expanded and contracted in the spring slot 34. Specifically, the outer side surface of the first ear portion 13 extends downward, and the outer side surface of the second ear portion 14 extends upward, until the outer side surface of the first ear portion 13 is connected to the outer side surface of the second ear portion 14 to form the spring slot 34.

[0059] It can be understood that the spring slot 34 can limit the spring 33 so that the spring 33 can only be compressed up and down and does not protrude outward from between the first ear 13 and the second ear 14, which can make the movement of the handle more stable.

[0060] Some embodiments of the present invention provide an optical power meter, comprising the universal interface 100 of the optical power meter described in any one of the above embodiments.

[0061] It can be understood that the embodiment of the present invention provides that the connector on the optical power meter is inserted into the optical power meter docking screw port 11 on the universal interface 100 of the optical power meter.

[0062] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
