Description

Technical Field

[0001] This invention relates to the field of fiber optic connector end-face inspection equipment, and more specifically to a detection trigger structure for fiber optic connector end-face inspection. Background Technology

[0002] Currently, fiber optic connector end-face testing equipment uses mechanical switches to trigger the equipment. However, mechanical switches have a high failure rate and low reliability, resulting in a short equipment lifespan. Summary of the Invention

[0003] The features and advantages of the present invention are set forth in part in the description which follows, or may be apparent from the description, or may be learned by practicing the invention.

[0004] The purpose of this invention is to provide a detection triggering structure for an optical fiber connector end face inspection device, which adopts a non-contact triggering method to extend the device's lifespan.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a detection trigger structure for fiber optic connector end face detection, including a photoelectric sensor installed on a fiber optic connector end face detection device and a movable part installed on a clamping device. The movable part is provided with a reflective surface. The movable part has a first position on the clamping device. When the movable part is in the first position, the light emitted by the photoelectric sensor is reflected by the reflective surface and received by the photoelectric sensor.

[0006] The movable part is a rotatable part.

[0007] The rotatable component is mounted on the clamping device via a rotating shaft.

[0008] The rotatable component includes a base plate, a first clamping plate disposed on one side of the base plate, and a second clamping plate disposed on the other side of the base plate. A mounting hole is formed between the base plate, the first clamping plate, and the second clamping plate, and the rotating shaft is installed in the mounting hole.

[0009] The reflective surface includes a first reflective surface and a second reflective surface, which are arranged at an angle to each other.

[0010] The first reflective surface and the second reflective surface are arranged perpendicularly.

[0011] When the movable part is in the first position, the light emitted by the photoelectric sensor is received by the photoelectric sensor after being reflected by the first reflective surface.

[0012] The movable part has a second position on the clamping device. When the movable part is in the second position, the light emitted by the photoelectric sensor will not be received by the photoelectric sensor after being reflected by the reflective surface.

[0013] The reflective surface includes a first reflective surface and a second reflective surface, which are arranged at an angle to each other.

[0014] When the movable part is in the second position, the light emitted by the photoelectric sensor will not be received by the photoelectric sensor after being reflected by the first reflective surface and the second reflective surface.

[0015] The device starts working after the photoelectric sensor receives the signal, thus achieving non-contact silent triggering of the device to start working through the photoelectric sensor and reflective surface, improving reliability, reducing failure rate, extending device life, and eliminating the need to consider accuracy issues. Attached Figure Description

[0016] The present invention will be described in detail below with reference to the accompanying drawings and examples. The advantages and implementation methods of the present invention will become more apparent from this description. The accompanying drawings are for illustrative purposes only and do not constitute any limitation on the present invention. In the accompanying drawings:

[0021] Figure 5 This is a cross-sectional view of the detection trigger structure in the second position in an embodiment of the present invention. Detailed Implementation

[0022] like Figure 1As shown, the detection triggering structure for fiber optic connector end-face inspection includes a photoelectric sensor 1 mounted on a fiber optic connector end-face inspection device and a movable component mounted on a clamping device 2. After the fiber optic connector is mounted on the fixture, it is inspected by the fiber optic connector end-face inspection device. The fiber optic connector end-face inspection device and clamping device 2 are existing technologies. The movable component has a reflective surface and has a first position and a second position on the clamping device. The first position and the second position do not coincide. When the movable component is in the first position, the light emitted by the photoelectric sensor is reflected by the reflective surface and received by the photoelectric sensor. After the photoelectric sensor receives the light, the device starts working. Thus, non-contact, silent triggering of the device is achieved through the photoelectric sensor and the reflective surface, improving reliability, reducing the failure rate, extending the device lifespan, and eliminating the need to consider accuracy issues.

[0023] When the movable part is in the second position, the light emitted by the photoelectric sensor will not be received by the photoelectric sensor after being reflected by the reflective surface, thus the device is in the off state.

[0024] In this embodiment, the movable part is a rotatable part 3, which is mounted on the clamping device 2 via a rotating shaft 4. The rotating shaft 4 is threaded.

[0025] like Figure 1 and Figure 3 As shown, the rotatable component includes a base plate 31, a first clamping plate 32, and a second clamping plate 33. The first clamping plate 32 is vertically disposed on one side of the base plate 31, and the second clamping plate 33 is vertically disposed on the other side of the base plate 31. A mounting hole is formed between the base plate 31, the first clamping plate 32, and the second clamping plate 33. The upper part of the rotating shaft 4 is installed in the mounting hole. The clamping device has a through hole 23 for the rotating shaft to pass through. The other part of the rotating shaft 4 is located in the through hole 23, and the rotating shaft 4 can rotate in the through hole 23. The first clamping plate 32 and the second clamping plate 33 are fastened together by screws 6, thereby clamping the rotating shaft 4 and fixing the rotating shaft 4 in the mounting hole. The length of the second clamping plate 33 is greater than the length of the first clamping plate 32. Moving the second clamping plate 33 causes the rotatable component to rotate. In other embodiments, the rotatable component may rotate around the upper part of the rotating shaft, and the other part of the rotating shaft may be fixed in the through hole.

[0026] The reflective surface includes a first reflective surface 5 and a second reflective surface 7, which are arranged at an angle and adjacent to each other. When the rotatable part is in the first position, the light emitted by the photoelectric sensor 1 is reflected by the first reflective surface 5 and then received by the photoelectric sensor 1. When the rotatable part is in the second position, the light emitted by the photoelectric sensor 1 is reflected by the first reflective surface 5 and then not received by the photoelectric sensor 1.

[0027] In this embodiment, the first reflective surface 5 and the second reflective surface 7 are arranged perpendicularly. The first reflective surface 5 is located on the outer surface of the base plate 31, and the second reflective surface 7 is located on the outer surface of the first clamping plate 32. Both the first and second reflective surfaces are planar. The light emitted by the photoelectric sensor 1 is perpendicular to an outer surface 21 of the clamping device 2. When the rotatable part is in the first position, the first reflective surface 5 is parallel to the outer surface 21. (Reference) Figure 5 When the rotatable part is in the second position, the first reflective surface 5 and the outer surface 21 form a certain angle, preferably 45 degrees, and the second reflective surface 7 and the outer surface 21 also form a certain angle, preferably 45 degrees.

[0028] like Figure 2 and Figure 3 As shown, when the rotatable part is in the first position on the clamping device 2, the light emitted by the photoelectric sensor 1 is vertically reflected by the first reflective surface 5 and received by the photoelectric sensor 1. The photoelectric sensor 1 responds, and the fiber optic connector end face detection device is in the triggered state and starts to work.

[0029] like Figure 4 and Figure 5 As shown, when the rotatable part is in the second position on the clamping device 2, the light emitted by the photoelectric sensor 1 is reflected to both sides into the surrounding environment by the first reflective surface 5 and the second reflective surface 7, and cannot be received by the photoelectric sensor 1. The photoelectric sensor 1 has no response, and the fiber optic connector end face detection device is in a non-triggered state.

[0030] like Figure 1 As shown, the clamping device 2 is provided with a notch 24, the rotatable part 3 is installed in the notch 24, and a clearance area 22 communicating with the notch 24 is provided on one side of the notch 24. The clearance area 22 facilitates the rotation of the rotatable part 3.

[0031] The preferred embodiments of the present invention have been described above with reference to the accompanying drawings. Those skilled in the art can implement the present invention in various modifications without departing from its scope and spirit. For example, a feature shown or described in one embodiment can be used in another embodiment to obtain yet another embodiment. The above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
