[0040] Figure 8 1 is a structural block diagram of an embodiment of the fiber alignment instrument of the utility model. In the embodiment of the utility model, the fiber alignment instrument for optical fiber jumper inspection includes a base 100, a cover 200, an optical sensor 300 and a control board 400.

[0041] The base 100 has a fiber clamping groove 110 for forming a fiber clamping channel SC, and the fiber clamping groove 110 includes a bending portion, and the optical fiber forms a bending section at the bending portion. The cover 200 is movably connected to the base 100, and the cover 200 has a protrusion 210 matching the shape of the fiber clamping groove 110 and guide grooves 220 located on both sides of the protrusion 210.

[0042] The fiber analyzer has an open state and a clamping state. In the open state, the protrusion 210 is away from the fiber clamping slot 110, so that the notch of the fiber clamping slot 110 is exposed. In the clamping state, the cover 200 covers the notch of the fiber clamping slot 110 and forms a fiber clamping channel SC.

[0043] The optical sensor 300 is installed in the base 100, and the detection end of the optical sensor 300 faces the fiber clamping slot 110 and can detect the light leakage signal of the optical fiber in the fiber clamping channel SC. The control board 400 is arranged in the base 100 and is electrically connected to the optical sensor 300. The control board 400 is configured to generate optical fiber detection information according to the light leakage signal.

[0044] In the embodiment of the utility model, in the clamping state, the cover 200 covers the base 100, and the protrusion 210 and the guide groove 220 of the cover 200 and the fiber clamping groove 110 of the base 100 form a fiber clamping channel SC. The cover 200 rotates or slides relative to the base 100.

[0045] Specifically, the cover 200 can be slidably connected to the base 100, or the cover 200 can be rotatably connected to the base 100 via a rotating shaft. When the cover 200 is slidably connected to the base 100, the cover 200 switches between the open state and the clamped state through sliding motion. When the cover 200 slides to cover the fiber clamping groove 110 of the base 100, it enters the clamped state, and when the cover 200 slides to expose the fiber clamping groove 110 of the base 100, it enters the open state.

[0046] When the cover 200 is rotatably connected to the base 100, the cover 200 rotates relative to the base 100 to switch between the clamping state and the open state. When the clamping state is switched to the open state, the notch of the fiber clamping groove 110 is exposed to the outside, and the optical fiber can be taken out of the fiber clamping groove 110 or placed in the fiber clamping groove 110.

[0047] When the cover body 200 and the base 100 clamp the optical fiber in the fiber clamping channel SC, the guide groove 220 allows the optical fiber to extend relatively smoothly at the openings at both ends of the fiber clamping channel SC and on both sides of the protrusion, preventing the optical fiber from generating additional bends at the openings of the fiber clamping channel SC and on both sides of the protrusion, resulting in additional loss of the optical signal of the optical fiber and affecting the detection results of the fiber analyzer.

[0048] The fiber aligning instrument of the embodiment of the utility model is provided with guide grooves 220 on both sides of the raised portion 210 of the cover body 200, so that when the cover body 200 is covered on the base 100, the guide grooves 220 of the cover body 200, the raised portion 210 and the fiber clamping groove 110 of the base 100 form a fiber clamping channel SC. When the optical fiber is clamped in the fiber clamping channel SC by the cover body 200 and the base 100, the guide grooves 220 can reduce the pressure of the cover body 200 on the optical fiber located at the entrance and exit of the fiber clamping channel SC, thereby reducing the bending degree of the optical fiber located at the entrance and exit of the fiber clamping channel SC, reducing the loss of optical signals, and improving the detection accuracy of the optical fiber detection device.

[0049] In some embodiments, the inner wall surface of the guide groove 220 is in an arc shape with a concave arrangement, and in the clamping state, the opening of the fiber clamping channel SC extends toward the direction of the protruding portion 210 .

[0050] In this embodiment, when the optical fiber is clamped by the fiber aligning instrument, the guide groove 220 can prevent the optical fiber at the opening of the fiber clamping channel SC from being pressed by the cover 200, resulting in additional bending of the optical fiber at the opening of the fiber clamping channel SC. Since the inner wall surface of the guide groove 220 is in a concave arc shape, the optical fiber at the opening of the fiber clamping channel SC can be offset toward the direction close to the protrusion 210, so that the optical fiber in the fiber clamping channel SC only forms a bending section at the bending part of the fiber clamping groove 110, and the optical fiber at the opening of the fiber clamping channel SC can extend smoothly to avoid additional bending.

[0051] In some embodiments, the fiber analyzer further includes a shading baffle 500, which is movably disposed at the openings on both sides of the fiber clamping channel SC. In the clamping state, the shading baffle 500 at least partially isolates the interior of the fiber clamping channel SC from the exterior.

[0052] In this embodiment, when the optical fiber is clamped in the fiber clamping channel SC, the shading baffle 500 can rise, and while the optical fiber is abutted against the inner wall surface of the guide groove 220, it can also isolate the fiber clamping channel SC from the outside, thereby shielding the external ambient light to the greatest extent and preventing the external ambient light from entering the fiber clamping channel SC and interfering with the light sensor 300.

[0053] In some embodiments, one end of the light shielding baffle 500 is telescopically connected to the base 100, and the other end has an arc-shaped slot 510, the slot opening of the slot 510 faces the guide slot 220, and the shape of the slot 510 matches the shape of the optical fiber.

[0054] In the clamping state, the light shielding baffle 500 extends toward the guide groove 220 , and the optical fiber is abutted against the inner wall surface of the guide groove 220 by the slot 510 .

[0055] In this embodiment, when the optical fiber is clamped in the fiber clamping channel SC, the light shielding baffle 500 rises from the base 100, abuts the optical fiber against the inner wall surface of the guide groove 220, and limits the optical fiber through the slot 510, so that the opening of the fiber clamping channel SC is closed to the greatest extent, preventing external ambient light from entering the fiber clamping channel SC. At the same time, the slot 510 of the light shielding baffle 500 can prevent the optical fiber from being damaged or bent while abutting the optical fiber against the inner wall surface of the guide groove 220.

[0056] In some embodiments, the base 100 further includes a mounting groove 120 , which is disposed at an edge of the base 100 and located in the fiber clamping groove 110 , and the shading baffle 500 is telescopically disposed in the mounting groove 120 and is slidably connected to the inner wall surface of the mounting groove 120 .

[0057] In this embodiment, the light shielding baffle 500 is telescopically arranged in the installation groove 120. In the open state, when the optical fiber needs to be placed in the fiber clamping groove 110, the light shielding baffle 500 can be retracted into the installation groove 120 to facilitate the placement of the optical fiber into the fiber clamping groove 110. When the fiber aligner is in the clamping state and the optical fiber is clamped in the fiber clamping channel SC, the light shielding baffle 500 can extend from the installation groove 120 and abut the optical fiber against the inner wall surface of the guide groove 220.

[0058] In some embodiments, one of the surface of the light-shielding baffle 500 and the inner wall surface of the mounting groove 120 is provided with a protruding sliding rail portion, and the other is provided with a recessed sliding groove portion. The surface of the light-shielding baffle 500 is limited in the mounting groove 120 through the cooperation between the sliding rail portion and the sliding groove portion and is slidably connected to the inner wall surface of the mounting groove 120.

[0059] In this embodiment, the rail portion can be arranged on the surface of the light shielding baffle 500, and the groove portion can be arranged on the inner wall surface of the mounting groove 120, or the rail portion can be arranged on the inner wall surface of the mounting groove 120, and the groove portion can be arranged on the surface of the light shielding baffle 500. The cooperation between the rail portion and the groove portion can make the light shielding baffle 500 slidably arranged in the mounting groove 120, reduce the friction between the light shielding baffle 500 and the mounting groove 120, and prevent the light shielding baffle 500 from shaking in the mounting groove 120.

[0060] In some embodiments, the fiber analyzer further includes an elastic member 600 , which is disposed in the mounting groove 120 , with one end of the elastic member 600 connected to the mounting groove 120 , and the other end of the elastic member 600 connected to the light shielding plate 500 .

[0061] In this embodiment, in the clamped state, when the optical fiber is clamped in the fiber clamping channel SC, the elastic member 600 applies elastic force to the light shielding baffle 500, so that the light shielding baffle 500 can abut the optical fiber against the inner wall surface of the guide groove 220. In the open state, when the optical fiber needs to be placed in the fiber clamping groove 110, the light shielding baffle 500 retracts into the installation groove 120 and compresses the elastic member 600, so that the elastic member 600 stores elastic force. After the optical fiber is clamped in the fiber clamping channel SC, the elastic member 600 applies the stored elastic force to the light shielding baffle 500, and the light shielding baffle 500 abuts the optical fiber against the inner wall surface of the guide groove 220.

[0062] In some embodiments, the width of the light shielding plate 500 is the same as the width of the fiber clamping channel SC.

[0063] In this embodiment, by setting the light shielding baffle 500 to have the same width as the fiber clamping channel SC, the light shielding baffle 500 can close the opening of the fiber clamping channel SC to the greatest extent, thereby reducing the interference of external ambient light on the optical sensor 300.

[0064] In some embodiments, the fiber analyzer further includes a display panel 700, which is disposed on a surface of the base 100 or a surface of the cover 200. The display panel 700 is electrically connected to the control board 400, and the control board 400 is configured to control the display panel 700 to display optical fiber detection information.

[0065] In this embodiment, in this embodiment, the display panel 700 can be set on the surface of the cover body 200 or the surface of the base 100, and the control board 400 can control the display panel 700 to display the optical fiber detection information, so that the display panel 700 displays the optical power, optical direction, optical wavelength and other information of the optical fiber clamped by the fiber analyzer, and the user can confirm the corresponding optical fiber clamped by the fiber analyzer according to the information displayed on the display.

[0066] In some embodiments, the fiber analyzer further includes: a communication module 800 , the communication module 800 is electrically connected to the control board 400 , and the control board 400 is configured to control the communication module 800 to send the optical fiber detection information outward.

[0067] In this embodiment, the fiber aligner sends the fiber detection information to the outside through the communication module 800, and the external device can obtain the corresponding fiber aligner's fiber detection information and display the fiber detection information, so that the operator can easily check and identify the optical power, optical direction, optical wavelength and other information of each optical fiber clamped by the fiber aligner. Exemplarily, the communication module 800 can be a Bluetooth module, a mobile communication module 800, etc., which is not specifically limited here.

[0068] In some embodiments, the fiber analyzer further includes a charging port, a switch assembly, and a power storage element. The charging port and the switch assembly are disposed on the surface of the base 100 and are electrically connected to the control board 400. The power storage element is disposed in the base 100 and is electrically connected to the control board 400. An external power source can supply power to the power storage element through the charging port. The power storage element is used to supply power to the control board 400. The switch assembly is used to control the on-off between the power storage element and the control board 400.
