[0038] Figure 1 A schematic diagram of the structure of an embodiment of the optical signal monitoring terminal of the utility model; Figure 2 This is a structural schematic diagram of a cover body of an embodiment of the optical signal monitoring terminal of the utility model; Figure 3 A schematic diagram of the structure of a base of an embodiment of the optical signal monitoring terminal of the utility model; Figure 4 A schematic diagram of the structure of a fiber clamping slot of an embodiment of the optical signal monitoring terminal of the utility model; Figure 5 The present invention provides an optical signal monitoring terminal 100 for clamping an optical fiber, and the optical signal monitoring terminal 100 includes a base 120 , a cover 110 , a rotating shaft 140 , an elastic member 160 , a detector 130 and a control board 150 .

[0039] The base 120 has a fiber clamping groove 122 for forming a fiber clamping channel, and the fiber clamping groove 122 includes a bending portion, and the optical fiber forms a bending section at the bending portion. The rotating shaft 140 rotatably connects the cover body 110 and the base 120, so that the optical signal monitoring terminal 100 has an open state and a clamping state. In the open state, the cover body 110 is away from the fiber clamping groove 122, so that the notch of the fiber clamping groove 122 is exposed; in the clamping state, the cover body 110 covers the notch of the fiber clamping groove 122.

[0040] The elastic member 160 elastically connects the cover 110 to the rotating shaft 140, and the elastic member 160 is configured to reset the optical signal monitoring terminal 100 to the clamping state. The detector 130 is disposed in the cover 110 or the base 120, and the detection end of the detector 130 faces the fiber clamping groove 122 and can detect the light leakage signal of the optical fiber located in the fiber clamping channel. The control board 150 is disposed in the base 120 and electrically connected to the detector 130, and the control board 150 is configured to generate optical fiber detection information according to the light leakage signal.

[0041] In this embodiment, the bending portion of the fiber clamping groove 122 is located in the middle of the fiber clamping groove 122. When the cover body 110 is covered on the base 120, the gap between the cover body 110 and the fiber clamping groove 122 forms a fiber clamping channel. Since the fiber clamping groove 122 is a part of the fiber clamping channel, the fiber clamping channel also has a bending portion and the bending portion makes the fiber clamping channel as a whole arc-shaped. The optical fiber located in the fiber clamping channel forms a bending section at the bending portion. The fiber clamping groove 122 can be formed by a concave setting of a part or a convex setting of a part to form a bending portion. The curvature of the bending portion can be set according to the size of the optical fiber, so that the fiber clamping channel formed by the cover body 110 and the base 120 can be compatible with optical fibers of corresponding sizes.

[0042] If the angle of the propagation path of the optical signal in the optical fiber is smaller 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 the leakage signal as described above, and the detector 130 generates optical fiber detection information based on the leakage signal.

[0043] In the embodiment of the utility model, when the cover plate is covered on the base 120, the gap between the cover plate and the fiber clamping groove 122 of the base 120 forms a fiber clamping channel, the detector 130 can detect the optical fiber in the fiber clamping channel and generate a light leakage signal, and the control board 150 generates optical fiber detection information according to the light leakage signal. The detector 130 can be a light sensor, a photoelectric sensor, etc., and the optical fiber detection information includes information such as the optical power and light direction of the optical fiber.

[0044] The cover body 110 and the base 120 of the optical signal monitoring terminal 100 of the utility model embodiment are connected by rotation, so that the cover body 110 can rotate relative to the base 120 to cover or expose the fiber clamping groove 122. In the open state, the fiber clamping groove 122 is exposed, and the optical fiber can be taken out of or put into the fiber clamping groove 122. In the clamping state, the cover body 110 covers the base 120, and the gap between the fiber clamping groove 122 of the base 120 and the cover body 110 forms a fiber clamping channel, and the cover body 110 clamps the optical fiber in the fiber clamping channel. When the fiber clamping groove 122 is exposed, the elastic member 160 can apply an elastic force to the cover body 110, so that the optical signal monitoring terminal 100 is reset to the clamping state, and the user can easily open the cover body 110 and clamp the optical fiber.

[0045] In some embodiments, one of the cover body 110 and the base 120 includes a protruding first limiting portion M1, and the other includes a recessed first limiting groove M2, and the shape of the first limiting portion M1 matches the shape of the first limiting groove M2; when the optical signal monitoring terminal 100 is in a clamped state, the first limiting portion M1 extends into the first limiting groove M2, so that the cover body 110 is limited to the base 120.

[0046] In this embodiment, the first limiting portion M1 is disposed on the cover body 110, and the first limiting groove M2 is disposed on the base 120, or the first limiting portion M1 may be disposed on the base 120, and the first limiting groove M2 may be disposed on the cover body 110, which is not limited in the present invention.

[0047] When the optical signal monitoring terminal 100 is in a clamping state, the cover body 110 is covered on the base 120 and covers the fiber clamping groove 122, and the optical fiber is clamped between the cover body 110 and the base 120. At this time, the first limiting portion M1 extends into the first limiting groove M2, and the cover body 110 is limited to the base 120 and can accurately clamp the optical fiber, thereby avoiding the problem of inaccurate optical fiber detection results or damage to the optical fiber due to the cover body 110 deviating from the base 120.

[0048] Furthermore, the first limiting groove M2 is disposed on the outer peripheral surface of the base 120 adjacent to the fiber clamping groove 122 , and the notch of the first limiting groove M2 faces the cover 110 , and the first limiting portion M1 is located on the outer peripheral surface of the cover 110 and extends toward the base 120 .

[0049] In this embodiment, when the optical signal monitoring terminal 100 is in the clamping state, the first limiting portion M1 extends into the first limiting groove M2, that is, the side of the base 120 where the first limiting groove M2 is located is adjacent to the side of the cover 110 where the first limiting portion M1 is located. When the elastic member 160 applies elastic force to the cover 110 so that the cover 110 covers the fiber clamping groove 122, the cooperation between the first limiting portion M1 and the first limiting groove M2 can prevent the cover 110 from deviating in the process of covering the base 120, so that the cover 110 is accurately covered on the base 120, and the optical fiber is accurately clamped in the fiber clamping channel by the cover 110.

[0050] In some embodiments, the elastic member 160 has a protruding torsion rod 161, and the cover body 110 also includes a torsion groove 111, which is located on the side of the cover body 110 facing the base 120, and the torsion rod 161 extends into the torsion groove 111; the elastic member 160 can apply elastic force to the cover body 110 through the torsion rod 161, so that the cover body 110 is covered on the base 120.

[0051] In this embodiment, the torsion bar 161 of the elastic member 160 is located in the torsion groove 111 of the cover body 110. The elastic force generated by the elastic member 160 can be applied to the cover body 110 through the torsion bar 161, so that when the optical signal monitoring terminal 100 is in the open state, the cover body 110 can automatically reset to a state covering the fiber clamping groove 122 of the base 120, and automatically switch the optical signal monitoring terminal 100 from the open state to the clamping state.

[0052] In some embodiments, the cover body 110 also includes a pressing portion 112, and the base 120 also includes an adjusting portion 121. The pressing portion 112 is located on one side of the cover body 110 and is opposite to the adjusting portion 121. The pressing portion 112 and the adjusting portion 121 extend obliquely away from each other, so that there is an angle between the pressing portion 112 and the adjusting portion 121.

[0053] In this embodiment, when the optical signal monitoring terminal 100 is in a clamping state, a force is applied to the pressing portion 112 toward the base 120. When the force is greater than the elastic force generated by the elastic member 160, the cover body 110 can rotate relative to the base 120, so that the pressing portion 112 is close to the adjusting portion 121, and the fiber clamping groove 122 is exposed to the outside. At this time, the optical fiber located in the fiber clamping groove 122 can be taken out or the optical fiber can be placed in the fiber clamping groove 122.

[0054] When the force applied to the pressing portion 112 is reduced or eliminated, the elastic force generated by the elastic member 160 can restore the cover 110 to a state covering the fiber clamping groove 122 , so that the optical signal monitoring terminal 100 automatically switches from the open state to the clamping state.

[0055] In some embodiments, the torsion groove 111 is located in the pressing portion 112, and the pressing portion 112 can abut against the adjusting portion 121 when subjected to a force acting toward the base 120, so that the optical signal monitoring terminal 100 is in an open state; in the open state, the elastic member 160 can apply an elastic force to the pressing portion 112, so that the pressing portion 112 is separated from the adjusting portion 121, and the optical signal monitoring terminal 100 switches from the open state to the clamped state.

[0056] In this embodiment, when a force is applied to the pressing portion 112 toward the base 120, since the torsion groove 111 is located in the pressing portion 112, when the pressing portion 112 is close to the adjusting portion 121, the elastic member 160 will be compressed together, thereby generating an elastic force. When the force applied to the pressing portion 112 is reduced or eliminated, the elastic force generated by the elastic member 160 is applied to the pressing portion 112 through the torsion rod 161, causing the pressing portion 112 to move in the opposite direction, and the cover body 110 rotates relative to the base 120, so that the cover body 110 finally covers the fiber clamping groove 122.

[0057] In some embodiments, the optical signal monitoring terminal 100 further includes an identification module 170, which is disposed in the base 120, and is electrically connected to the control board 150. The identification module 170 stores identification information corresponding to the optical fiber and can send the identification information to the outside. The identification module 170 can be a passive electronic tag, an active electronic tag, or other types of electronic tags, such as an RFID tag.

[0058] In this embodiment, the identification module 170 stores optical fiber identification information, which is identification information of the optical fiber held by the optical signal monitoring terminal 100. The identification module 170 can send the optical fiber identification information to the outside. According to the optical fiber identification information stored in the identification module 170, the optical fiber held by the optical signal monitoring terminal 100 can be determined and identified. When it is necessary to distinguish and identify the optical fiber to be detected from multiple optical fibers, the optical fiber identification information stored in the identification module 170 can avoid the problem of misjudgment and misdetection.

[0059] In some embodiments, the cover 110 has a protruding clamping portion 113 and the base 120 has a recessed portion 123 . The shapes of the clamping portion 113 and the recessed portion 123 match each other. The clamping portion 113 can clamp the optical fiber in the recessed portion 123 so that the optical fiber is confined in the fiber clamping channel.

[0060] In this embodiment, when the optical signal monitoring terminal 100 is in a clamping state, the gap between the clamping portion 113 and the recessed portion 123 forms a bending portion of the fiber clamping channel, so that the optical fiber in the fiber clamping channel forms a bending section, so that the detector 130 can detect the optical fiber.

[0061] In this embodiment, the detector 130 and the control board 150 are located in the base 120. The detector 130 and the control board 150 are not limited to being located in the base 120. In some embodiments, the detector 130 and the control board 150 may also be located in the cover 110. The detector 130 and the control board 150 may both be located in the cover 110 or both be located in the base 120, or one may be located in the cover 110 and the other may be located in the base 120.

[0062] In some embodiments, the cover body 110 also includes a second limiting groove 114, and the base 120 also includes a protruding second limiting portion 124. The second limiting portion 124 is arranged at the groove of the fiber clamping groove 122 on the side close to the elastic member 160. The second limiting portion 124 extends in the same direction as the extension direction of the fiber clamping groove 122. The second limiting groove 114 is located on a side of the cover body 110 facing the base 120 and is arranged opposite to the second limiting portion 124.

[0063] In this embodiment, when the optical signal monitoring terminal 100 is in a clamping state, the second limiting portion 124 can extend into the second limiting groove 114, so that the second limiting portion 124 can prevent the optical fiber in the fiber clamping channel from deviating toward the rotating shaft 140, thereby ensuring that the optical fiber can be correctly clamped in the fiber clamping channel.

[0064] In some embodiments, the optical signal monitoring terminal 100 further includes a display screen 180 , which is disposed on the cover 110 or the base 120 . The display screen 180 is electrically connected to the control board 150 , and the control board 150 is configured to control the display screen 180 to display optical fiber detection information.

[0065] In this embodiment, the display screen 180 can be set on the surface of the cover body 110 or the surface of the base 120. The control board 150 can control the display screen 180 to display optical fiber detection information, so that the display screen 180 displays the optical power, optical direction, optical wavelength and other information of the optical fiber clamped by the optical signal monitoring terminal 100. The user can determine which optical fiber is clamped by the optical signal monitoring terminal 100 based on the information displayed on the display.

[0066] In some embodiments, the optical signal monitoring terminal 100 further includes a communication module 180 , which is electrically connected to the control board 150 , and the control board 150 is configured to control the communication module 180 to send optical fiber detection information externally.

[0067] In this embodiment, the optical signal monitoring terminal 100 sends the optical fiber detection information to the outside through the communication module 180, and the external device can obtain the optical fiber detection information of the corresponding optical signal monitoring terminal 100 and display the optical fiber detection information, so that the operator can easily check and identify the optical power, optical direction, optical wavelength and other information of the optical fiber clamped by each optical signal monitoring terminal 100. Exemplarily, the communication module 180 can be a Bluetooth module, a mobile communication module, etc., which is not specifically limited here.

[0068] In some embodiments, the optical signal monitoring terminal 100 further includes a charging port, a switch module 190, and a power storage element. The charging port and the switch module 190 are disposed on the base 120 and are electrically connected to the control board 150. The power storage element is disposed in the base 120 and is electrically connected to the control board 150.
