Description

Technical Field

[0001] The invention relates to the technical field of optical fiber modules, and in particular to an optical fiber communication module with a dustproof structure. Background Art

[0002] The fiber optic module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic devices include transmitting and receiving parts.

[0003] For example, an optical fiber module with a dustproof structure with announcement number CN217820978U includes an optical fiber module, a dustproof box is slidably arranged on one side of the optical fiber module, an inflatable airbag is fixed to the inner wall of the dustproof box, a slide plate is slidably arranged on the inner wall of the dustproof box and extends to the inner wall of the optical fiber module, a magnetic plate is slidably arranged inside the dustproof box, a rotating rod is rotatably connected to the inner wall of the dustproof box, a fixed block in contact with the slide plate is fixed to one end of the rotating rod, a magnetic rod in contact with the magnetic plate is fixed to the other end of the rotating rod, and a magnetic rod in contact with the magnetic plate is connected to the inner wall of the optical fiber module through a convex block, a dustproof box, an inflatable airbag, a slide plate, a rotating rod, a fixed block, a magnetic rod, a magnetic plate, a piston rod, and the like. The setting of the piston cavity solves the problem of poor dust resistance of the existing optical fiber module. When the optical fiber is inserted into the dustproof box, the slide plate is driven to slide, so that the piston rod pressurizes the inside of the piston cavity, and then the airbag expands and fits tightly against the outer wall of the optical fiber to achieve the effect of dust and moisture prevention. However, the device only uses a single airbag to protect the optical fiber from dust, which is not convenient for assisting the positioning and preventing the optical fiber from falling off. When the optical fiber is pulled, a gap appears between the optical fiber and the wiring part, or even it becomes loose. At this time, dust invades the inside of the optical fiber communication module, which reduces the protection effect and wiring stability of the device and has certain defects.

[0058] An auxiliary component 8 is arranged between the connecting part 4 and the plug-in part 5. The auxiliary component 8 includes a fixed disk 81 and an outer groove 82. A pressure plate 83 is slidably connected inside the outer groove 82. The outer sides of the pressure plate 83 are inclined to facilitate the compression and contraction of the pressure plate 83.

The screw rod 71 rotates to drive the outer sleeve 72 to move toward the optical fiber line part 1, and the outer sleeve 72 slides on the slide rod 73 and stretches the spring 1 74. The outer sleeve 72 simultaneously drives the slide plate 76 to slide inside the slide groove 75, and the slide groove 75 compresses the spring 2 78 and drives the inner rod 710 to move. The inner rod 710 drives the piston 711 to slide inside the sleeve 79, and the piston 711 compresses the gas inside the sleeve 79.

[0064] The movement of the outer shell 72 drives the push rod 719 to move, and the push rod 719 drives the annular member 720 to squeeze the upper inclined surface of the adjusting rod 716, so that the adjusting rod 716 moves toward the inside of the outer cylinder 3, and the adjusting rod 716 drives the arc block 717 to move and stretch the spring three 718, so that the arc blocks 717 around clamp the connecting part 4, and the arc blocks 717 around are in a completely closed state, and the arc blocks 717 will block the fixing plate 81, thereby reducing the loosening of the optical fiber line part 1.

[0065] When the plug-in part 5 is inserted into the optical fiber module 2, the pressure plate 83 is squeezed by one end of the outer cylinder 3. The pressure plate 83 is a symmetrically arranged arc segment. The pressure plate 83 will compress the spring four 84 and shrink into the outer groove 82, so that the fixed plate 81 can slide smoothly into the interior of the outer cylinder 3 to complete the plug-in connection between the plug-in part 5 and the optical fiber module 2. After the pressure plate 83 is separated from one end of the outer cylinder 3, the elastic force of the spring four 84 drives the pressure plate 83 to rebound and reset, so that the pressure plate 83 is stuck on the inner wall of the outer cylinder 3, and one end of the outer cylinder 3 will assist in blocking the pressure plate 83, which also reduces the loosening or disengagement of the plug-in part 5.

[0066] When the push rod 719 moves, the push rod 719 drives the card plate 86 to move on the block 85. The card plate 86 is an elastic block. After passing each block 85, the card plate 86 will be stuck in the interval position of the block 85, thereby playing an auxiliary limiting role, improving the clamping stability of the arc block 717, and when resetting later, the block 85 can be separated from the card plate 86 by rotating.
