In order to facilitate the fixing of the optical cable after connection by a user, the embodiment of the invention can be used, firstly, the user needs to strip a part of the outer skin of the optical cable according to the requirement of optical cable connection, and weld the optical fibers in the optical cable, then fix the welded optical fibers in the fixing component, then the user plugs the optical cable into the lower slot 6 and preliminarily fixes the optical fibers through the fastener, then the user rotates the rotating plate 2, so that the upper box cover 3 is buckled on the lower box cover 4, the upper slot 5 of the upper box cover 3 is aligned with the lower slot 6 of the lower box cover 4, the optical cable is buckled, further fixing of the optical cable is realized, then the upper box cover 3 and the lower box cover 4 are fixed through bolts and nuts, and then the fixing operation of the optical cable connection ends is finished, and meanwhile, two pairs of through holes formed by the upper slot 5 and the lower slot 6 are formed, so that the embodiment of the invention can accommodate two pairs of optical cables.
When the user rotates the upper box cover 3, the connecting block 7 at the upper box cover 3 can be buckled to the rotating plate 2 at the lower box cover 4, the limiting groove 8 on the surface of the connecting block 7 is buckled to the rotating plate 2, when the rotating plate 2 contacts with the elastic bulge 9 at the notch of the limiting groove 8, the elastic bulge 9 is extruded and deformed, so that the rotating plate 2 can be clamped into the limiting groove 8, and then the elastic bulge 9 is restored, so that the rotating plate 2 is limited in the limiting groove 8, the preliminary fixing of the upper box cover 3 is realized, the upper box cover 3 is prevented from being buckled on the lower box cover 4 without one hand when the user overhauls, and the user can vacate two hands to overhaul, so that the overhauling efficiency of the user is improved.
After the limiting groove 8 is blocked into the rotating plate 2, the rotating plate 2 is adsorbed with the magnet sheet 10, so that the rotating plate 2 and the upper box cover 3 fixedly connected with the rotating plate 2 are fixed, and the phenomenon that the user overhauls is influenced because the upper box cover 3 shakes when the user overhauls, the upper box cover 3 continuously drives the rotating plate 2 to strike the bottom of the limiting groove 8, and the lower box cover 4 connected with the connecting block 7 is vibrated.
When the user welds the optical fibers, the heat shrinkage tube is sleeved on the welding section of the optical fibers, the welding section of the optical fibers is protected by the heat shrinkage tube, then the user clamps the two ends of the heat shrinkage tube into the clamping grooves 15 on the top surface of the one-side clamping seat 14 respectively, then the user clamps the optical fibers by the eight-shaped fiber coiling method, then plugs the coiled optical fibers into one of the arrangement grooves 17 on the top surface of the limiting seat 16, if the user connects two groups of optical cables, the user can clamp the two ends of the heat shrinkage tube at the connecting end into the clamping grooves 15 on the top surface of the other-side clamping seat 14 respectively, and the rest of the group of optical fibers are coiled by the eight-shaped fiber coiling method and plugged into the other arrangement groove 17 on the top surface of the limiting seat 16, so that the two groups of connected optical fibers are separated, and the user can detect or pick out the optical fibers with problems in the future conveniently.
After the user has coiled the optical fiber, the user needs to insert the coiled optical fiber into the arranging groove 17 through the gap between the baffle 20 and the limiting seat 16 and block the optical fiber through the baffle 20, so that the optical fiber is prevented from falling out of the arranging groove 17 due to scratch of the user.
When the optical fibers contained in the optical cable are more, a user can fix the optical fibers and the heat shrinkage tubes on the optical fibers through the optical fiber boxes 12 according to the requirement, then rotate the limiting plate 22 to enable the limiting plate 22 to be attached to the surface of the side wall of the limiting post 21, compress the torsion spring, then sleeve the optical fiber boxes 12 with the optical fibers on the limiting post 21, loosen the limiting plate 22, recover the torsion spring, drive the limiting plate 22 to deflect towards the optical fiber boxes 12 and finally be perpendicular to the side wall of the limiting post 21, so that the effect of preventing the optical fiber boxes 12 from being separated from the surface of the limiting post 21 is achieved, and the compatibility of the embodiment of the invention to the multi-core optical cable is improved.
When the user buckles the upper box cover 3 to the lower box cover 4, the spring 23 on the surface of the upper box cover 3 can press the pressing plate 24 to the limiting column 21, and the sliding hole 25 on the surface of the pressing plate 24 can penetrate through the limiting column 21, so that the pressing plate 24 can press the optical fiber boxes 12, a plurality of optical fiber boxes 12 can be stacked together, and the optical fibers are prevented from being damaged due to shaking of the optical fiber boxes 12 between the upper box cover 3 and the lower box cover 4.
When a user fixes the end part of the optical cable through the fastening component, the user needs to pass the fixing reinforcing core in the optical cable through the fixing hole 27, then the user needs to screw the handle 29, thereby driving the pressing rod 28 to rotate, further enabling the bottom surface of the pressing rod 28 to press the fixing reinforcing core of the optical cable on the surface of the fixing hole 27, and then winding the rest part of the fixing reinforcing core on the surface of the fixing seat 26, so that when the optical cable is prevented from being pulled by external force, the optical cable is pulled out of the lower box cover 4, and meanwhile, the elastic belt 30 on the handle 29 can be used for fixing the small flashlight, so that the user can check the optical fiber box 12 in the lower box cover 4 and the optical fiber condition inside the optical fiber box under the condition of darkness conveniently.
When a user only connects a pair of optical cables, two pairs of upper slots 5 and lower slots 6 are idle, in order to prevent rainwater from flowing into the upper box cover 3 and the lower box cover 4 from between the idle upper slots 5 and lower slots 6, the user can screw the rubber plugs 32 at the ends of the connecting ropes 31 into the through holes formed by the upper slots 5 and the lower slots 6, so that the idle upper slots 5 and lower slots 6 are blocked, and rainwater is prevented from entering the upper box cover 3 and the lower box cover 4.
Before the optical cable is put into the lower slot 6, a user needs to pass the optical cable through the rubber ring 34, and then the upper box cover 3 is buckled on the lower box cover 4, so that gaps between the optical cable and the inner walls of the upper slot 5 and the lower slot 6 are filled through the rubber ring 34, the probability of rainwater infiltration is further reduced, and the optical fibers inside the upper box cover 3 and the lower box cover 4 are protected.
