[0002] The optical fiber fusion splicers on the market only have the function of optical fiber fusion splicing and do not have the function of preventing laser damage. Sometimes, when the optical fiber is not taken out and a certain power laser is accidentally connected to the optical fiber, it will burn out the fixtures, optical fiber fixture seats, discharge needle seats, etc. of the fusion splicer, resulting in the fusion splicer being unable to be repaired and only being scrapped, causing relatively large losses.

[0011] A further solution is that the mounting bracket is provided with two adjustment chutes, and the two adjustment chutes are distributed on both sides of the detection slot in the horizontal direction.

[0018] The present utility model will be further described below in conjunction with the drawings and embodiments. Specific Embodiments
[0019] Referring to Figures 1 to 4 , the fiber optic fusion splicer 1 includes a base 11, a cover 12, a display screen 10 and two fiber optic detection devices 2. The base 11 is provided with two fiber clamps 111 along the optical path direction. The cover 12 is hinged to the base 11 and covers the two fiber clamps 111. The cover 12 is provided with through holes 121 at both ends in the optical path direction. The display screen 10 is connected to the base 11 and can be used to display the presence or absence of the optical fiber.
[0020] Two mounting brackets 21 are respectively installed on the side walls 112 of the base 11 on both sides in the optical path direction. The fiber optic detection device 2 includes a mounting bracket 21 and a detection sensor 24. The mounting bracket 21 is provided with a detection slot 22 penetrating along the optical path direction. The detection slot 22 has a loading port above in the vertical direction. The detection slot 22 is located outside the through hole 121 in the optical path direction. The detection slot 22 is used to place the optical fiber 3. The detection sensor 24 is installed in the mounting bracket 21 and is used to detect the optical fiber 3 located in the detection slot 22.
[0021] The mounting bracket 21 is provided with two adjustment sliding grooves 23. The two adjustment sliding grooves 23 are distributed on both sides of the detection groove 22 in the horizontal direction. The adjustment sliding grooves 23 extend in the vertical direction. Screws pass through the adjustment sliding grooves 23 and are connected to the side wall 112. The screw heads of the screws are adjacent to the groove walls of the adjustment sliding grooves 23 for adjusting the height position of the mounting bracket 21.
[0022] In this embodiment, the detection sensor 24 is an infrared sensor. The infrared sensor is arranged at the bottom of the detection groove 22 and detects the optical fiber 3 in the detection groove 22. The detection signal line of the infrared sensor is connected to the main control circuit board of the optical fiber fusion splicer. Of course, the detection sensor can be a trigger type travel switch or a pressure sensor, etc., which can also detect the presence or absence of the optical fiber.
[0023] An aviation connector 13 is arranged on the base 11 of the optical fiber fusion splicer. The signal output cable is connected by using the aviation connector 13, and then the signal output cable is connected to the laser 14.
[0024] The optical fiber fusion splicer includes two optical fibers 3. One optical fiber 3 is used to connect to the laser 14 and is placed in one of the optical fiber clamps 111, while the other optical fiber 3 is placed on the other optical fiber clamp 111 and is used to output a laser signal. The rear end of the other optical fiber 3 can be connected to an optical device 15. The optical device 15 can be a collimator, a filter, a fiber grating, etc. After the optical fibers 3 are fused, the laser 14 can be used to pass light through the optical fibers 3, and the optical path will pass through the optical device 15 on the high-power laser test optical path. If the optical fiber is not taken out of the optical fiber fusion splicer, the fusion splicer will be burned out. Therefore, through the optical fiber detection device 2 in this case, the presence or absence of the optical fiber can be detected. When there is an optical fiber, the optical fiber fusion splicer is driven into the protection mode, and then a signal is fed back to the laser, causing the laser to stop outputting laser, thereby protecting the fusion splicer.
[0025] As can be seen from the above, by arranging the optical fiber detection device on both sides in the optical path direction, and the two optical fibers 3 are respectively arranged along the optical path direction, the detection sensor is used to detect whether the optical fiber is in the detection groove, and the detection signal line can be introduced into the main control circuit board of the fusion splicer. When there is no optical fiber in the detection groove, the fusion splicer is in the protection state. Furthermore, the presence or absence of the optical fiber can be conveniently detected by the infrared sensor, and the position of the mounting bracket and the detection sensor can be adjusted in cooperation with the adjustment sliding groove.
