In the embodiment of the utility model, the optical fiber detection assembly 100 includes a detection board 110 and a control board 120 .

[0047] The detection board 110 includes at least two sensors 111, and the sensors 111 can detect optical fibers and generate optical fiber detection signals. The control board 120 is detachably electrically connected to the detection board 110, and the surface of the detection board 110 is arranged opposite to the surface of the control board 120, and one side of the control board 120 has a groove 121, and the sensor 111 is arranged on the surface of the detection board 110 facing the control board 120 and extending toward the groove 121.

[0048] In the embodiment of the utility model, if the angle of the propagation path of the optical signal in the optical fiber is less than the critical angle required for total reflection, the optical signal will leak out of the optical fiber when the optical fiber is bent to a certain curvature, generating a light leakage signal. The sensor 111 can be a light sensor, a photoelectric sensor, etc., which generates a fiber detection signal when sensing the light leakage signal of the optical fiber; the control board 120 can obtain the optical direction information and / or optical power information and / or optical wavelength information of the optical fiber according to the obtained optical fiber detection signal.

[0049] In the prior art, the sensor 111 of the optical fiber detection device is generally directly arranged on the surface of the circuit board and electrically connected to the circuit board. When the circuit board is installed in the shell of the optical fiber detection device, the detection end of the sensor 111 extends to the optical fiber clamped by the shell, and the battery of the optical fiber detection device is generally arranged on the side of the circuit board away from the sensor. The thickness of the sensor, circuit board and battery are superimposed to form a three-layer structure. Sufficient space needs to be reserved inside the shell of the optical fiber detection device in the prior art to place the sensor 111, circuit board and battery into the shell.

[0050] In this embodiment, the detection board 110 and the control board 120 are detachably arranged to facilitate the assembly of the optical fiber detection assembly 100. Since the surface of the detection board 110 and the surface of the control board 120 are arranged opposite to each other, the sensor 111 on the detection board 110 is located in the gap formed between the detection board 110 and the control board 120, and the optical fiber detection assembly 100 further includes a power supply element 130, which is arranged on the surface of the control board 120 facing the detection board 110, so that the power supply element 120 and the detection board 110 are located on the same surface of the control board 120.

[0051] When the optical fiber detection component 100 is placed in the shell, the sensor 111 can extend to the optical fiber to be detected through the slot 121 of the control board 120. Compared with the prior art, the sensor 111 and the power supply element 120 of the optical fiber detection component 100 are arranged on the same side of the control board 120. The sensor 111, the power supply element 120 and the control board 120 form a two-layer structure. Compared with the prior art, the thickness is reduced, the structure is more compact, and the space occupied by the optical fiber detection component 100 is reduced.

[0052] The circuit board of the optical fiber detection assembly 100 of the embodiment of the utility model is separated into a detection board 110 and a control board 120, and the sensor 111 is arranged on the surface of the detection board 110. Since the control board 120 has a slot 121 and the detection board 110 and the control board 120 are arranged opposite to each other, when the detection board 110 and the control board 120 are connected, the sensor 111 is located between the control board 120 and the detection board 110, and the sensor 111 can extend to the slot 121 of the control board 120 to avoid the control board 120 blocking the sensor 111. The embodiment of the utility model reduces the thickness of the optical fiber detection assembly 100 by stacking the detection board 110 and the control board 120, so that the structure of the optical fiber detection assembly 100 is more compact.

[0053] In some embodiments, the detection board 110 also includes at least one first electrical connector 112, and the control board 120 also includes at least one electrical connection portion 122.

[0054] In this embodiment, the detection board 110 and the control board 120 are detachably electrically connected via the first electrical connector 112 and the electrical connecting portion 122. During the production process of the optical fiber detection assembly 100, the detection board 110 and the control board 120 can be easily assembled through the design of the detachable connection between the first electrical connector 112 and the electrical connecting portion 122, thereby improving the production efficiency.

[0056] In this embodiment, two first electrical connectors 112 are disposed on both sides of the detection board 110, two sensors 111 are located between the two first electrical connectors 112, and both sides of the slot 121 of the control board 120 are provided with an electrical connection portion 122. The first electrical connector 112 is disposed opposite to the electrical connection portion 122, and the first electrical connector 112 can be detachably electrically connected to the electrical connection portion 122, which is convenient for assembly, so that the detection board 110 and the control board 120 can be detachably electrically connected, and the detection ends of the two sensors 111 can face the notch formed by the slot 121 of the control board 120, so as to detect the optical fiber.

[0057] In some embodiments, the first electrical connector 112 has a plurality of pins 1121 extending toward the control board 110 , and the electrical connection portion 122 has a plurality of slots 1221 matching the pins 1121 , and the pins 1121 are detachably disposed in the slots 1221 .

[0058] In this embodiment, the pin of the first electrical connector 112 extends into the slot of the electrical connection portion 122 , so that the first electrical connector 112 and the electrical connection portion 122 are detachably electrically connected, thereby achieving detachable electrical connection between the detection board 110 and the control board 120 .

[0059] In some embodiments, the control board 120 further includes an amplifying module 123 . The amplifying module 123 is electrically connected to the sensor 111 . The amplifying module 123 is configured to amplify the optical fiber detection signal.

[0060] In this embodiment, the amplification module 123 is used to obtain the optical fiber detection signal generated by the sensor 111 detecting the optical fiber and perform gain amplification on the optical fiber detection signal for subsequent signal processing.

[0061] In some embodiments, the control board 120 further includes a conversion module 124 , which is electrically connected to the amplification module 123 , and the conversion module 124 is configured to convert the analog signal of the amplified optical fiber detection signal into a digital signal.

[0062] In this embodiment, the conversion module 124 is used to obtain the amplified optical fiber detection signal and convert the analog signal of the amplified optical fiber detection signal into a digital signal for subsequent signal processing.

[0063] In some embodiments, the control board 120 further includes a processing module 125, which is electrically connected to the conversion module 124 and configured to obtain optical direction information and / or optical power information and / or optical wavelength information of the optical fiber according to the optical fiber detection signal.

[0064] In this embodiment, the processing module 125 is used to obtain the optical fiber detection signal converted into a digital signal, and the processing module 125 obtains the optical direction information and / or optical power information and / or optical wavelength information of the optical fiber clamped by the optical fiber detection device according to the obtained optical fiber detection signal. Among them, the optical direction information is the light transmission direction in the optical fiber, the optical power information is the optical power size in the optical fiber, and the optical wavelength information is the wavelength of the light in the optical fiber.

[0065] In some embodiments, the optical fiber detection assembly 100 further includes a power supply element 130 and a second electrical connector 140 , wherein the second electrical connector 140 electrically connects the control board 120 to the power supply element 130 , and the power supply element 130 is disposed on a surface of the control board 120 facing the detection board 110 .

[0066] In this embodiment, the second electrical connector 140 electrically connects the power supply element 130 to the control board 120. When the control board 120 and the detection board 110 are electrically connected, the power supply element 130 is used to supply power to the control board 120 and the detection board 110. By arranging the power supply element 130 and the detection board 110 on the same side of the control board 120, the thickness of the optical fiber detection assembly 100 can be reduced.

[0075] Figure 5 This is a schematic structural diagram of an embodiment of the micro optical fiber monitoring terminal 200 of the utility model; Figure 6 This is a structural block diagram of an embodiment of the micro optical fiber monitoring terminal 200 of the utility model; Figure 7 This is a structural schematic diagram of a cover body of an embodiment of the micro optical fiber monitoring terminal of the utility model; Figure 8 A schematic diagram of the structure of a base of an embodiment of the micro optical fiber monitoring terminal of the utility model; Fig. 9 It is a cross-sectional schematic diagram of an embodiment of the miniature optical fiber monitoring terminal of the utility model; Fig.10 The present invention also provides a micro optical fiber monitoring terminal 200, which includes the optical fiber detection assembly 100 and a housing assembly 210 of any of the above embodiments of the present invention.

[0076] The optical fiber detection assembly 100 is disposed in a shell assembly 210. The shell assembly 210 has a fiber clamping channel SC for the optical fiber to pass through. The fiber clamping channel SC includes a bending portion, and the optical fiber forms a bending section at the bending portion. The detection end of the sensor 111 faces the fiber clamping channel SC. The sensor 111 is configured to detect the optical fiber located in the fiber clamping channel SC and generate an optical fiber detection signal.

[0077] The optical fiber detection assembly 100 includes a detection board 110 and a control board 120. The detection board 110 includes at least two sensors 111, which can detect optical fibers and generate optical fiber detection signals. The control board 120 is detachably electrically connected to the detection board 110, and the surface of the detection board 110 is arranged opposite to the surface of the control board 120, and a groove 121 is provided on one side of the control board 120. The sensor 111 is arranged on the surface of the detection board 110 facing the control board 120 and extending toward the groove 121.

[0078] In this embodiment, the fiber clamping channel SC has a bending portion, so that the optical fiber forms a bending section, and the bending portion of the fiber clamping channel SC extends into the groove 121 of the control board 120, so that the detection end of the sensor 111 located on the detection board 110 can face the fiber clamping channel SC, so that the sensor 111 can detect the bending section of the optical fiber located in the fiber clamping channel SC.

[0079] It is conceivable that if the sensor 111 is directly set on the control board 120, then the sensor 111 will be located on the side of the control board 120 facing the fiber clamping channel SC, and the power supply element 130 will be located on the side of the control board 120 away from the fiber clamping channel SC. Since the sensor 111 needs to detect the bending section of the optical fiber located in the fiber clamping channel SC, the shell assembly 210 needs to increase its volume to accommodate the portion of the sensor 111 that extends relative to the control board 120, which will make the micro fiber optic monitoring terminal 200 bloated.

[0080] And if Fig.10 As shown, the sensor 111 of the conventional optical fiber detection device is tilted relative to the control board, and the pins of the sensor 111 need to be twisted and bent to be electrically connected to the control board 120. Therefore, sufficient space needs to be reserved in the housing of the optical fiber detection device for the pins of the sensor 111 to be bent, so that the pins of the sensor 111 can be smoothly electrically connected to the control board 120. This tilted setting makes the sensor 111 occupy too much space, further exacerbating the problem of the optical fiber detection device being too bulky.

[0081] Through the detachable design of the control board 120 and the detection board 110 of this embodiment, the sensor 111 is arranged on the detection board 110, so that the sensor 111 and the power supply element 130 are located on the same surface of the control board 120 and between the control board 120 and the detection board 110. Through the groove 121 of the control board 120, the bent part of the fiber clamping channel SC can extend into the groove 121, and the sensor 111 can detect the detection section of the optical fiber. In addition, the sensor 111 is vertically arranged on the detection board 110, so that the pin of the sensor 111 can be directly electrically connected to the detection board 110 very conveniently without bending, thereby greatly reducing the space occupied by the optical fiber detection component 100 and making the size of the micro optical fiber monitoring terminal 200 more compact.

[0082] The micro optical fiber monitoring terminal 200 of the embodiment of the utility model includes an optical fiber detection component 100, the circuit board of the optical fiber detection component 100 is separated into a detection board 110 and a control board 120, and the sensor 111 is arranged on the surface of the detection board 110. Since the control board 120 has a slot 121 and the detection board 110 and the control board 120 are arranged opposite to each other, when the detection board 110 and the control board 120 are connected, the sensor 111 is located between the control board 120 and the detection board 110, and the sensor 111 can extend to the slot 121 of the control board 120 to avoid the control board 120 blocking the sensor 111. The embodiment of the utility model reduces the thickness of the optical fiber detection component 100 by stacking the detection board 110 and the control board 120, and the structure of the optical fiber detection component 100 is more compact, which reduces the internal space of the micro optical fiber monitoring terminal 200 occupied by the optical fiber detection component 100, making the micro optical fiber monitoring terminal 200 smaller in size.

[0083] In some embodiments, the shell assembly 210 includes a cover body 211 and a base 212, and the surface of the base 212 facing the cover body 211 has a fiber clamping groove 2121, and the cover body 211 is rotatably connected to the base 212, so that the micro fiber optic monitoring terminal 200 has an open state and a clamping state; in the open state, the cover body 211 is away from the fiber clamping groove 2121, and the notch of the fiber clamping groove 2121 is exposed; in the clamping state, the cover body 211 covers the notch of the fiber clamping groove 2121, and the gap between the cover body 211 and the fiber clamping groove 2121 forms a fiber clamping channel SC.

[0084] In this embodiment, the bending portion of the fiber clamping groove 2121 is located in the middle of the fiber clamping groove 2121. When the cover body 211 is covered on the base 212, the gap between the cover body 211 and the fiber clamping groove 2121 forms a fiber clamping channel SC. Since the fiber clamping groove 2121 is a part of the fiber clamping channel SC, the bending portion of the fiber clamping groove 2121 forms the bending portion of the fiber clamping channel SC and the bending portion makes the fiber clamping channel SC arc-shaped as a whole. The optical fiber located in the fiber clamping channel SC can form a bending section at the bending portion.

[0085] The fiber clamping groove 2121 can be formed by a partially concave setting or a partially convex setting to form a bending portion, and the curvature of the bending portion can be set according to the size of the optical fiber, so that the fiber clamping channel SC formed by the cover body 211 and the base 212 can be compatible with optical fibers of corresponding sizes.

[0086] In some embodiments, the micro fiber optic monitoring terminal 200 further includes a rotating shaft 230 and an elastic member 240. The rotating shaft 230 rotatably connects the cover 211 and the base 212. The elastic member 240 is sleeved on the rotating shaft 230 and is configured to reset the micro fiber optic monitoring terminal 200 to a clamped state.

[0087] In this embodiment, the elastic member 240 elastically connects the cover 211 to the rotating shaft 230. When the cover 211 rotates relative to the base 212, the elastic member 240 can apply elastic force to the cover 211, so that the micro optical fiber monitoring terminal 200 is reset to the clamped state. When the optical fiber clamped by the micro optical fiber monitoring terminal 200 needs to be replaced or the optical fiber needs to be placed in the fiber clamping channel SC of the micro optical fiber monitoring terminal 200, the cover 211 is rotated to expose the fiber clamping groove 2121, at which time the optical fiber can be replaced or placed in the fiber clamping groove 2121. The cover 211 is loosened, and the elastic member 240 can reset the cover 211, so that the cover 211 is covered on the base 212.

[0088] In some embodiments, the cover 211 has a protruding clamping portion M1, and the base 212 has a recessed portion M2. The shapes of the clamping portion M1 and the recessed portion M2 match, and the clamping portion M1 can clamp the optical fiber in the recessed portion M2, so that the optical fiber is confined in the fiber clamping channel SC.

[0089] In this embodiment, the recessed portion M2 is located in the middle of the fiber clamping groove 2121. When the micro fiber optic monitoring terminal 200 is in a clamping state, the gap between the clamping portion M1 and the recessed portion M2 forms a bending portion of the fiber clamping channel SC, so that the optical fiber located in the fiber clamping channel SC forms a bending section, so that the sensor can detect the optical fiber.

[0090] In some embodiments, the micro fiber optic monitoring terminal 200 further includes a display screen 220 , which is disposed on the surface of the housing assembly 210 , and is electrically connected to the control board 120 , which is configured to control the display screen 220 to display the fiber optic detection signal.

[0091] In this embodiment, the display screen 220 is electrically connected to the connection socket 150 provided on the control board 120, and the processing module 125 of the control board 120 can send the processed optical fiber detection signal to the display screen 220, so that the display screen 220 displays the optical direction information and / or optical power information and / or optical wavelength information of the optical fiber.

[0092] The above description is only a preferred 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 inventive 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.
