The embodiment of the utility model provides an optical fiber surveying device 100 for optical signal detection, and the optical fiber surveying device 100 includes a housing component 110, at least two optical sensors 120 and a control board 130.

[0040] The housing assembly 110 has a fiber clamping channel SC for the optical fiber to pass through, and the fiber clamping channel SC includes a bending portion, and the optical fiber forms a bending section at the bending portion. At least two optical sensors 120 are installed in the housing assembly 110, and the detection ends of the optical sensors 120 are oriented toward the bending portion of the fiber clamping channel SC, and the detection ends of each optical sensor 120 are oriented parallel to each other. The optical sensors 120 can detect the bending section of the optical fiber to generate an optical power signal. The control board 130 is disposed in the housing assembly 110, and the control board 130 is electrically connected to the optical sensor 120. The control board 130 is configured to obtain optical fiber detection information based on the optical power signal. Among them, the optical fiber detection information includes the optical transmission direction, optical power information and optical wavelength information of the optical fiber.

[0041] In the embodiment of the utility model, the detection end of the optical sensor 120 is oriented toward the bending portion of the fiber clamping channel SC. During the assembly process of the optical fiber detection device 100, when the optical sensor 120 is installed on the control board 130, since the detection ends of each optical sensor 120 are oriented parallel to each other, the angles between each optical sensor 120 and the control board 130 are the same. Compared with the tilted arrangement of each optical sensor 120 and the different orientations of each optical sensor 120, the embodiment of the utility model can more conveniently connect the optical sensor 120 to the control board 130, thereby improving assembly efficiency.

[0042] The at least two optical sensors 120 of the optical fiber inspection device 100 of the embodiment of the utility model are used to detect the bending section of the optical fiber to generate an optical power signal. Since the orientations of the optical sensors 120 are parallel to each other, the optical sensors 120 can be easily installed on the control board 130, thereby solving the problem that the inclined optical sensors 120 are inconvenient to install on the control board 130.

[0043] In some embodiments, the bent portion of the fiber clamp channel SC has a long strip-shaped detection hole N1, the opening of the detection hole N1 extends along the surface of the bent portion of the fiber clamp channel SC, and at least two optical sensors 120 are arranged in the detection hole N1 at intervals, so that the detection end of the optical sensor 120 faces the bent portion of the fiber clamp channel SC.

[0044] In this embodiment, since the detection hole N1 is in the shape of an elongated strip, the two or more optical sensors 120 located in the detection hole N1 can be spaced apart from each other, and the detection end of each optical sensor 120 can be directed toward different parts of the bending section of the optical fiber located in the fiber clamping channel SC to obtain optical fiber detection information.

[0045] like Figure 3 As shown, further, the housing assembly 110 further includes an isolating member 113, which is disposed in the middle of the detection hole N1, so that the detection hole N1 is divided into at least two parts, and each optical sensor 120 is disposed in one of the divided parts of the detection hole N1.

[0046] In this embodiment, the isolating member 113 can separate the detection hole N1 into two parts, three parts or more parts, and the two optical sensors 120 extend into the corresponding parts of the detection hole N1 respectively, so that the detection ends of the two optical sensors 120 can face different positions of the bending part of the fiber clamping channel SC. When the optical fiber is clamped in the fiber clamping channel SC, the bending part of the fiber clamping channel SC can form a bending section of the optical fiber, so that the optical sensor 120 can detect the bending section of the optical fiber and generate an optical power signal.

[0047] In some embodiments, the bending portion of the fiber clamping channel SC has at least two detection holes N1, and the detection holes N1 are arranged at intervals. At least one detection hole N1 is located on one side of the middle of the fiber clamping channel SC, and at least one detection hole N1 is located on the other side of the middle of the fiber clamping channel SC, so that the extension directions of the bending sections of the optical fibers detected by different optical sensors 120 are different.

[0048] In this embodiment, the fiber clamping channel SC is provided with two or more detection holes N1, and at least one detection hole N1 is provided on both sides of the bending part of the fiber clamping channel SC, so that the two optical sensors 120 respectively detect different positions of the bending section of the optical fiber, and the controller can obtain the optical fiber detection information according to the difference in the optical power signals detected by the two optical sensors 120.

[0049] In some embodiments, the light sensor 120 is vertically disposed on the control board 130 .

[0050] like Figure 4 As shown, in the prior art, the two optical sensors 120 are arranged obliquely relative to the control board 130. Since the detection end of the optical sensor 120 is arranged obliquely, the pins of the optical sensor 120 are also inclined relative to the control board 130, which is very inconvenient when electrically connecting the pins of the optical sensor 120 to the control board 130. This arrangement also makes the process of installing the optical sensor 120 into the detection hole N1 complicated and time-consuming.

[0051] In this embodiment, the control board 130 includes a control module 131 and a detection module 132. The detection module 132 is detachably connected to the control module 131 and is disposed on a side of the control module 131 away from the fiber clamping channel SC. The optical sensor 120 is disposed on a side of the detection module 132 facing the control module 131. Compared with the tilted arrangement of the optical sensor 120 relative to the control board 130, the optical sensor 120 cooperates with the detection hole N1. The vertical arrangement relative to the control board 130 can conveniently place the optical sensor 120 in the detection hole N1 and also makes the electrical connection between the pins of the optical sensor 120 and the control board 130 very convenient, making it easier to weld the optical sensor 120 to the control board 130.

[0052] In some embodiments, the extension direction of the electrical connection end of the optical sensor 120 is perpendicular to the control board 130 , and the electrical connection end of the optical sensor 120 is electrically connected to the control board 130 .

[0053] In this embodiment, since the extension direction of the electrical connection end of the optical sensor 120 is perpendicular to the control board 130 and the two optical sensors 120 are oriented in the same direction and the optical sensors 120 are vertically arranged on the control board 130, the two optical sensors 120 are vertically arranged on the control board 130. By vertically arranging the two optical sensors 120 relative to the control board 130, the assembly method of the optical fiber scanning device 100 is simplified and the production efficiency is improved.

[0054] In some embodiments, the shell assembly 110 includes a cover body 111 and a base 112, the side of the cover body 111 facing the base 112 has a protrusion M1 and a first guide groove A1 located on both sides of the protrusion M1, the side of the base 112 facing the cover body 111 has a recessed portion M2 matching the protrusion M1 and a second guide groove A2 located on both sides of the recessed portion M2; when the cover body 111 is covered on the base 112, the protrusion M1 and the recessed portion M2 form a bending portion of the fiber clamping channel SC, and the first guide groove A1 and the second guide groove A2 form a partial fiber clamping channel SC.

[0055] In this embodiment, when the cover 111 is covered on the base 112, the protruding portion M1 of the cover 111 and the first guide grooves A1 located on both sides of the protruding portion M1 and the recessed portion M2 of the base 112 and the second guide grooves A2 located on both sides of the recessed portion M2 together form a fiber clamping channel SC. The cover 111 can rotate relative to the base 112, so that the recessed portion M2 and the second guide groove A2 of the base 112 are exposed or covered by the cover 111. When the recessed portion M2 and the second guide groove A2 of the base 112 are exposed, the optical fiber can be taken out or placed in the recessed portion M2 and the second guide groove A2 of the base 112. When the cover 111 is covered on the base 112, the optical fiber can be clamped in the fiber clamping channel SC, so that the optical sensor 120 can detect the bending section of the optical fiber.

[0056] Furthermore, the inner wall surface of the first guide groove A1 is in a concave arc shape.

[0057] If the first guide groove A1 and the second guide groove A2 extend parallel to the horizontal plane, a larger bending angle will be generated at the connection between the fiber clamping channel SC formed by the first guide groove A1 and the second guide groove A2 and the bent portion of the fiber clamping channel SC formed by the protrusion M1 and the recessed portion M2, causing additional loss of the optical fiber.

[0058] In the present embodiment, the recessed setting of the inner wall surface of the first guide groove A1 can greatly reduce the bending degree between part of the optical fibers in the fiber clamping channel SC formed by the first guide groove A1 and the second guide groove A2 and part of the optical fibers in the bent portion of the fiber clamping channel SC formed by the protrusion M1 and the recessed portion M2, so as to avoid the loss of optical power due to additional bending of the optical fiber and reduce the influence of the optical fiber detection device 100 on the optical fiber transmission performance when clamping the optical fiber.

[0059] In some embodiments, the cover body 111 is rotatably connected to the base 112, and the optical fiber inspection device 100 further includes an elastic member 140, which elastically connects the cover body 111 to the base 112. The elastic member 140 can apply elastic force to the cover body 111 or the base 112 to reset the cover body 111 to a state where it is covered on the base 112.

[0060] In this embodiment, the optical fiber inspection device 100 has an open state and a clamped state. In the open state, the protrusion M1 of the cover body 111 is away from the recessed portion M2 of the base 112, and the recessed portion M2 and the second guide groove A2 of the base 112 are exposed; in the clamped state, the cover body 111 is covered on the base 112 to form a clamping channel. In this embodiment, the elastic member 140 is a torsion spring, which is sleeved on the rotating shaft.

[0061] The cover 111 and the base 112 are rotatably connected via a rotating shaft, and the elastic member 140 is sleeved on the rotating shaft to elastically connect the cover 111 and the base 112. The elastic member 140 is configured to reset the optical fiber inspection device 100 to a clamped state. When it is necessary to remove or replace the optical fiber clamped by the optical fiber inspection device 100, the optical fiber inspection device 100 can be switched to an open state by rotating the cover 111. The elastic force of the elastic member 140 can keep the cover 111 in a clamped state to prevent the optical fiber from falling off from the optical fiber inspection device 100.

[0062] In other embodiments, the optical fiber surveying device 100 includes a buckle and a matching piece that cooperates with the buckle. One of the buckle and the matching piece is disposed on the base 112, and the other is disposed on the cover 111. For example, in this embodiment, the buckle may be disposed on the base 112, and the matching piece may be disposed on the cover 111. In the clamping state, the buckle is connected with the matching piece by a buckle, so that the cover 111 is covered on the base 112, and the optical fiber surveying device 100 is limited to the clamping state.

[0063] Alternatively, the cover 111 may be slidably connected to the base 112. Specifically, one of the cover 111 and the base 112 is provided with a slide rail, and the other is provided with a slide block that slides along the slide rail, and the cover 111 can slide along the slide rail on the base 112, so that the optical fiber inspection device 100 can switch between an open state and a clamped state.

[0064] In some embodiments, the optical fiber inspection device 100 further includes a switch assembly 150 and a power supply element 160. The switch assembly 150 is disposed in the housing assembly 110 and partially exposed to the outside. The power supply element 160 is disposed in the housing assembly 110. The switch assembly 150 is electrically connected to the control board 130 and the power supply element 160. The switch assembly 150 is configured to control the on and off of the control board 130 and the power supply element 160.

[0065] In this embodiment, the power supply element 160 is used to supply power to the control board 130, and the switch assembly 150 electrically connects the power supply element 160 with the control board 130. The switch of the switch assembly 150 is arranged on the surface of the shell assembly 110. By controlling the closing and opening of the switch assembly 150, the on and off control of the control board 130 and the power supply element 160 is achieved.

[0066] In some embodiments, the optical fiber surveying device 100 further includes a display screen 180, which is disposed on the housing assembly 110 and is electrically connected to the control board 130. The control board 130 can control the display screen 180 to display optical fiber detection information. The optical fiber detection information includes optical power information, optical transmission direction, and optical wavelength information of the optical fiber clamped by the optical fiber surveying device 100.

[0067] In this embodiment, the control panel 130 can control the display screen 180 to display optical fiber detection information, so that the display screen 180 displays the optical power information, optical transmission direction, and optical wavelength information of the optical fiber clamped by the optical fiber inspection device 100. The user can identify which optical fiber is clamped by the optical fiber inspection device 100 based on the information displayed on the display.

[0068] In some embodiments, the optical fiber inspection device 100 further includes a communication module 170, which is electrically connected to the control board 130, and the control board 130 is configured to control the communication module 170 to send optical fiber inspection information to the outside.

[0069] In this embodiment, the communication module 170 can transmit the optical fiber detection information to the outside, so that the external device receives the optical fiber detection information. The external device can obtain the optical power information, optical transmission direction, and optical wavelength information of the optical fiber based on the received optical fiber detection information and identify which optical fiber is clamped by the optical fiber detection device 100 based on the optical fiber detection information.
