[0002] In the field of optical communication, the widespread application of fiber optic network makes the maintenance of optical communication system become crucial. As the key medium of optical signal transmission, the reliability of its connection and the accuracy of detection process directly affect the communication quality.

[0003] Among numerous optical communication maintenance instruments, red light pen has the advantages of simple operation, convenient carrying, etc., and is widely used in the installation, maintenance and troubleshooting of fiber optic network.

[0004] Red light pen can conveniently inject into optical fiber by emitting red light of a specific wavelength, thereby helping technicians to intuitively detect the continuity of optical fiber link. Its working principle is to use internal light-emitting elements, such as light-emitting diodes or laser diodes, to generate red light and couple the optical signal into the optical fiber through the optical fiber interface. If red light can be observed at the other end of the optical fiber, it indicates that the optical fiber link is connected; otherwise, there may be problems such as optical fiber breakage, excessive bending or poor connection.

[0005] Among numerous optical communication maintenance instruments, red light pen has the advantages of simple operation, convenient carrying, etc., and is widely used in the installation, maintenance and troubleshooting of fiber optic network.

When it contacts the light outlet, it is easy to transfer these pollutants to the surface of the light outlet, which will interfere with the normal transmission of red light signal, reduce the accuracy of detection, for example, may cause abnormal changes of red light intensity, increase scattering, etc., and further affect the accurate judgment of the state of optical fiber line.

DETAILED DESCRIPTION

[0026] In order to make the purpose and the advantage of the utility model more clearly and clearly, the utility model is specifically explained below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the protection range of the utility model specifically requested.

[0027] As Figures 1-7 Indicated, a kind of optical communication maintenance instrument, including red light pen main body 1, the one end of red light pen main body 1 is fixedly connected with light outlet 2, when the red light of the light emitting diode in red light pen main body 1 is emitted, it is radiated to outside by light outlet 2, when red light passes through optical fiber interface 5 and enters optical fiber line 3 inside, observation is carried out at the other end of optical fiber line 3, check whether there is red light to be seen;If obvious red light can be seen, it indicates that fiber is connected in this section;If red light cannot be seen, it can exist optical fiber break, the optical signal cannot pass due to too small bending radius, or the connection point has problem and so on fault.

[0028] In prior art, in order to make red light can be concentrated into optical fiber line 3 inside, optical fiber interface 5 is usually inserted into the inside of light outlet 2, but it is necessary to clean optical fiber interface 5 before inserting each time, to reduce the pollution of optical fiber interface 5 to light outlet 2, and the present technical scheme as Figure 1 And Figures 3-4As shown, the front end of the red light pen body 1 is fixedly connected with a circular tube sleeve 6 located outside the light outlet 2, the inner side of the circular tube sleeve 6 is fixedly connected with an annular positioning air bag 7, the annular positioning air bag 7 is communicated with a gas pressure adjusting mechanism for adjusting the gas pressure inside the annular positioning air bag 7, and the gas pressure adjusting mechanism can be fixedly connected outside the red light pen body 1 or the circular tube sleeve 6.

[0029] As shown in Figures 3-4 and Figure 7 , when the optical fiber line 3 is detected, the optical fiber connector 4 connected to one end of the optical fiber line 3 is inserted into the annular positioning air bag 7, and then the gas pressure adjusting mechanism is started to inflate the annular positioning air bag 7, so that the annular positioning air bag 7 inflates towards the optical fiber connector 4, until the annular positioning air bag 7 extrudes the inner wall of the optical fiber connector 4, and the positioning of the optical fiber connector 4 and the optical fiber interface 5 is completed. At this time, the optical fiber connector 4 and the annular positioning air bag 7 form a sealing structure, so that a sealed space is formed inside the circular tube sleeve 6, reducing the leakage of red light, and under the extrusion of the annular positioning air bag 7, the optical fiber connector 4 is uniformly stressed on the side, so that the optical fiber interface 5 at one end of the optical fiber connector 4 and the light outlet 2 are opposite, so that the red light emitted at the light outlet 2 is directly and directly irradiated into the optical fiber interface 5, and as shown in Figure 7 , after the positioning of the optical fiber connector 4 and the optical fiber interface 5 is completed, there is a certain interval distance L between the optical fiber interface 5 and the light outlet 2, so that the light outlet 2 and the optical fiber connector 4 are not in direct contact, so that during the detection of the optical fiber line 3, the optical fiber interface 5 and the light outlet 2 maintain a certain distance, reducing the pollution of the optical fiber interface 5 to the light outlet 2 during the detection.

[0030] The gas pressure adjusting mechanism can be a gas pump, or as shown in Figure 1 , Figure 3 and Figure 5 , that is, the gas pressure adjusting mechanism includes a gas storage container 8 fixedly connected outside the red light pen body 1, one end of the gas storage container 8 is communicated with the annular positioning air bag 7 through a gas guide pipe 10, and the gas storage container 8 is slidably connected with a gas pushing plate 9.

When the gas pushing plate 9 moves away from the gas guide pipe 10, the gas inside the annular positioning air bag 7 can be sucked into the gas storage container 8, so that the annular positioning air bag 7 shrinks, so that the volume of the annular positioning air bag 7 can be adjusted more simply.

[0032] Further, one end of the U-shaped rod 11 located outside the air storage container 8 is fixedly connected with a positioning magnet 12, and the material of the air storage container 8 is iron, so that the position of the air pushing plate 9 can be positioned by adsorbing the positioning magnet 12 outside the air storage container 8.

[0033] The positioning magnet 12 can also be replaced by other locking members, such as a locking screw threaded on the U-shaped rod 11, which can also position the air pushing plate 9 when the locking screw abuts against the air storage container 8.

[0034] As shown in Figure 4 and Figures 6-7 The inside of the circular pipe sleeve 6 and between the light outlet 2 and the annular positioning air bag 7 is also provided with an annular limiting plate 14, and the inner diameter of the annular limiting plate 14 is greater than the maximum outer diameter of the fiber connector 4, so that the fiber connector 4 and the light outlet 2 can be limited.

[0035] The front end of the red light pen body 1 is rotatably connected with a threaded pipe 17, the inside of the threaded pipe 17 is threadedly connected with a threaded rod 18, one end of the threaded rod 18 is fixedly connected with the annular limiting plate 14, and when the threaded pipe 17 rotates, the threaded rod 18 and the annular limiting plate 14 can be moved to adjust the position of the annular limiting plate 14 limiting the fiber connector 4.

[0036] The outside of the threaded pipe 17 is fixedly connected with a second bevel gear 21, the circular pipe sleeve 6 is rotatably connected with a knob 19, one end of the knob 19 located inside the circular pipe sleeve 6 is fixedly connected with a first bevel gear 20, and the first bevel gear 20 and the second bevel gear 21 are meshingly connected, so that the rotary kinetic energy can be transmitted to the threaded pipe 17 through the first bevel gear 20 and the second bevel gear 21 by rotating the knob 19, and the threaded pipe 17 can be rotated more simply.
