Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber cleaning, in particular to an optical fiber connector interface cleaning device. Background Art

[0002] Optical fiber has the advantages of strong long-distance transmission capability, good confidentiality, and strong anti-interference ability, and is widely used in transmission lines of wired networks. As a connecting device between two optical fibers, the optical fiber connector allows the optical signal to be continuous and form an optical path. It is an indispensable and most widely used passive device in the current optical communication system. A sleeve structure is set inside the optical fiber connector. When the two optical fibers are inserted into the sleeve, the end faces of the two optical fibers are precisely docked, so that the light energy output by the transmitting optical fiber is coupled to the receiving optical fiber to the maximum extent to complete the transmission of the optical signal. However, at the site of industrial enterprises, due to the harsh environment, dust and other pollutants are easily accumulated on the end faces of the optical fiber. These pollutants will directly weaken the transmission of the optical signal, and in severe cases, it will cause the signal transmission to be interrupted. Therefore, cleaning the end faces of the optical fiber is a necessary part of daily maintenance work.

[0003] At present, most of the cleaning of the optical fiber connection interface only focuses on the cleaning of the end face. For example, Chinese patent number CN109061809A discloses an optical fiber connector interface end face cleaner, including a housing, a cleaning needle connected to the housing, a first spindle and a second spindle arranged in the housing, and a driving assembly for driving the first spindle, the second spindle, and the cleaning needle to move, the second spindle is located between the first spindle and the cleaning needle, and the axis direction of the first spindle is perpendicular to the axis direction of the second spindle. The optical fiber connector interface end face cleaner of the present invention avoids the mutual contact between the used yarn and the unused yarn during the cleaning process, and prevents the used yarn from contaminating the unused yarn. Most of the common optical fiber cleaning pens on the market are of this type, but this type of cleaning tool can only clean the optical fiber end face, but cannot effectively clean the side wall of the sleeve. The contaminants left on the side wall of the cleaning sleeve can easily cause secondary contamination of the optical fiber end face.

[0004] Therefore, how to achieve simultaneous cleaning of the fiber optic interface end face and the sleeve side wall has become a breakthrough in improving fiber optic transmission signals. Utility Model Content

DETAILED DESCRIPTION

[0020] The utility model will be further described below in conjunction with the accompanying drawings.

[0021] An optical fiber connector interface cleaning device, such as Figure 1 As shown, it includes an inner tube 1, a sliding sleeve 2, a probe 3, a top wire head 4, a wire storage wheel 5, a wire take-up wheel 6, a wire storage box 8, a wire take-up box 9, a reset spring 7, a cleaning belt 13, and a silicone cap 14.

[0022] The inner tube 1 is a cylindrical structure with two ends open, and its front end is connected to the probe 3 by a thread, and its rear end is connected to the wire storage box 8 by a thread. The wire storage box 8 is equipped with a wire storage wheel 5 for winding the cleaning belt 13; the probe 3 is a hollow structure, and after the connection, the wire storage box 8, the inner tube 1 and the probe 3 form a connected cavity structure, and the cleaning belt 13 passes through the cavity. The probe 3 is a stepped shape including a small diameter end and a large diameter end. The outer diameter of the small diameter end is the same as the outer diameter of the inner tube 1, and the large diameter end is provided with an internal thread that matches the external thread at the front end of the inner tube 1.

[0023] The inner tube 1 is provided with a sliding sleeve 2 on the outside, and the sliding sleeve 2 and the large diameter end of the probe 3 are in clearance fit, so that they can slide forward and backward; a stopper is provided in the middle of the outer wall of the inner tube 1 to limit the backward position of the sliding sleeve 2. Since the outer diameter of the large diameter end is larger than the outer diameter of the inner tube 1, an annular cavity is formed between the inner wall of the sliding sleeve 2 and the outer wall of the inner tube 1, and a reset spring 7 is installed in the annular cavity; specifically, the front end of the reset spring 7 is fixed to the large diameter end of the probe 3, and the rear end of the reset spring 7 is fixed to the tail of the sliding sleeve 2, and the reset power is provided to the sliding sleeve 2 through the deformation of the spring.

[0024] A wire platform 12 protruding outward is arranged at the rear of the sliding sleeve 2, and a threading hole is arranged inside the wire; a wire take-up box 9 is arranged at the rear side of the wire platform 12, and the wire take-up box 9 is fixed on the outer wall of the inner tube 1, and the side of the wire take-up box 9 close to the wire platform 12 is open; a wire take-up wheel 6 is installed in the wire take-up box 9, and the cleaning belt 13 passes through the probe 3 and is wound onto the wire take-up wheel 6 through the wire platform 12 and the wire take-up box 9.

[0025] The wire take-up box 9 is also provided with a ratchet mechanism for driving the cleaning belt 13 to intermittently wind. Figure 2 , Figure 3 As shown, the ratchet mechanism is an external meshing ratchet mechanism, including a toothed disc 18 with external teeth, a spindle 17, a pawl 16, and a spring 15. The toothed disc 18, the spindle 17, the turntable 19, and the take-up wheel 6 are coaxially arranged, and the toothed disc 18 is connected to the spindle 17 in a transmission manner, and the turntable 19 is connected to the take-up wheel 6 in a transmission manner (the take-up wheel 6 is detachable) through the spring 15. The pawl 16 is fixed on the housing of the take-up box 9 and meshes with the toothed disc 18 for transmission. The pawl 16 always remains in a pop-up state under the action of the torque spring provided therewith. One end of the spring 15 is fixed on the turntable 19, and the other end is fixed on the spindle 17. A keyhole 20 is set at a section of the spindle 17 away from the spring 15. The spring key 11 passes through the take-up box 9 and is inserted into the keyhole 20 to realize the transmission connection. Specifically, use the spring key 11 to insert the keyhole 20 to twist the core shaft to drive the toothed disk 18 to rotate, the spring 15 is tightened to pull the turntable 19, and then the take-up wheel 6 is driven to rotate. After the cleaning belt 13 is tightened, the core shaft 17 is continued to be twisted to make the spring 15 continue to be tightened. After the twisting stops, the pawl 16 falls and blocks the toothed disk 18 so that it cannot rotate reversely. The spring 15 pulls the take-up wheel 6 to keep the cleaning belt 13 in a tightened state. When the sliding sleeve 2 is pushed forward, the clean cleaning belt is pulled out, and the cleaning belt is relaxed after resetting. The take-up wheel 6 rotates under the action of the spring tension to wind and tighten the cleaning belt 13.

[0026] The detachable transmission connection between the rotating disk 19 and the take-up wheel 6 is not limited in detail here. Various existing connection methods can be used as long as the detachable installation and transmission functions can be achieved, including but not limited to the matching connection between the card block and the card slot.

[0027] The front end of the sliding sleeve 2 is fixedly connected to the thread-pushing head 4, which is sleeved on the outside of the small-diameter end of the probe 3 and slides with the small-diameter end of the probe 3. The thread-pushing head 4 is a hollow conical cylinder, and its outer conical surface forms a transition conical surface between the sliding sleeve 2 and the small-diameter end of the probe 3; when the sliding sleeve 2 is pushed forward, the thread-pushing head 4 props up the cleaning belt 13 and pushes it out, and provides guidance for the cleaning belt 13 through its shape, so that the conveying process from the probe 3 to the conductor table 12 is smoother.

[0028] The cleaning tape 13 is usually a cotton cleaning tape 13 with good water absorption, such as cotton thread. The cleaning tape 13 is soaked in 75% ethanol and placed in the wire storage box 8 for standby use. In order to prevent the ethanol in the cleaning tape 13 from volatilizing, a silicone cap 14 is also provided on the outside of the probe 3; the elasticity of the silicone cap 14 allows it to fully fit the probe 3, so that the cavity between the wire storage wheel 5 and the probe 3 is sealed, effectively maintaining the wettability of the cleaning tape 13 inside the probe 3. When the size of the optical fiber port is large, multiple strands of cotton thread can be twisted together and used as the cleaning tape 13 to fully clean the optical fiber end face.

[0029] Furthermore, in order to enable the cleaning tape 13 to more fully contact the end face and side wall of the optical fiber interface, especially the junction between the end face and the side wall, the front end of the probe 3 is connected to a silicone convex edge 22, and a plurality of incisions are circumferentially arranged on the silicone convex edge 22; when the probe 3 contacts the end face of the optical fiber interface, a little force can be applied to disperse the silicone convex edge 22 circumferentially, so that the cleaning tape 13 also expands outward synchronously, fully contacts the junction between the end face and the side wall, and fully cleans the blind corner of the junction.

[0030] Furthermore, in order to ensure the wettability of the cleaning tape 13 at the probe 3, a wetting box 23 is also provided between the wire storage box 8 and the inner tube 1. The wetting box 23 includes an annular sealed cavity 25, in which 75% ethanol or other detergent is contained. A wetting sponge 24 is provided at the center of the sealing ring 21, and the outer edge of the wetting sponge 24 extends into the sealed cavity 25, so that ethanol can diffuse and wet the sponge 24 without leakage; a small hole for the cleaning tape 13 to pass through is provided in the middle of the wetting sponge 24, and the inner diameter of the small hole is not larger than the outer diameter of the cleaning tape 13, so that the cleaning tape 13 will fully contact and soak with the wetting sponge 24 when passing through. When the cleaning tape 13 passes out of the wire storage box 8, it is first soaked by the wetting sponge 24 to ensure that the cleaning tape 13 has sufficient humidity to prevent it from being too dry and scratching the surface of the optical fiber port.

[0031] The front end and rear end of the inner tube 1 are both provided with external threads, and the probe 3 and the wire storage box 8 matched therewith are both provided with internal threads to achieve thread matching. The front end of the moistening box 23 is provided with internal threads matched with the rear end of the inner tube 1, and the rear end is provided with external threads matched with the wire storage box 8, so as to realize the sequential connection of the inner tube 1, the moistening box 23 and the wire storage box 8.

[0032] It should be emphasized that in order to reduce the volatilization of ethanol in the cleaning tape 13 in the wire storage box 8, all the joints where the cleaning tape 13 passes through the cavity are sealed; the wire take-up box 9 does not need to be sealed, and the cleaning tape 13 is no longer recycled after being rolled up.

[0033] The storage wheel 5 and the take-up wheel 6 are both provided with a snap ring for fixing the end of the cleaning belt 13 to achieve stable winding of the cleaning belt 13. The storage wheel 5 and the take-up wheel 6 are both detachable, which is convenient for removing the old cleaning belt 13 and replacing the new cleaning belt 13.

[0034] It should be emphasized that the wire storage wheel 5 is a movable wheel with damping, and its rotation range is limited by the rotation range of the wire take-up wheel 6, and free rotation does not occur.

[0035] In addition, during actual use, multiple sets of probes 3 and top wire heads 4 with different diameters can be manufactured according to the specifications and dimensions of the optical fiber interface, and can be selected according to actual needs.

[0036] The working process of the utility model is:

[0037] The wire storage wheel wound with the cleaning tape is soaked in 75% ethanol and then installed in the wire storage box. The front end of the cleaning tape is inserted into the cavity of the inner cylinder and passed through the probe. After being wound outside, it enters the wire take-up box through the conductor table. The front end of the cleaning tape is fixed on the wire take-up wheel, and the spring key is turned to tighten the spring to make the cleaning tape tensioned.

[0038] During the cleaning operation, open the silicone cap, insert the probe into the sleeve of the fiber optic connector, press down moderately to make the cleaning tape fully contact the port of the fiber optic connector and the side wall of the connector sleeve, and rotate it manually so that the cleaning tape can wipe the fiber optic port and the connector sleeve at the same time.

[0039] After wiping one circle, push the sliding sleeve to replace and feed the cleaning belt; push the sliding sleeve and use the top thread head to tighten the cleaning belt. Because the take-up wheel is constrained by the ratchet and cannot reverse, only the cotton thread on the storage wheel is pulled out; after loosening, the sliding sleeve is reset by the action of the reset spring, and the take-up wheel rotates by the action of the spring, the used cleaning belt is retracted and tightened, and the cleaning belt is replaced.

[0040] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
