Description

Technical Field

[0001] This utility model relates to the field of optical communication module technology, specifically to an optical communication module optical cable fixing device. Background Technology

[0002] An optical module contains an optical transmitter and an optical receiver. Data is converted from electrical signals by the transmitting device into optical signals and transmitted through optical fiber. The optical module at the receiving end converts the received optical signals into electrical signals for processing by the receiving device. With the continuous improvement of network speed, it has become the mainstream transmission method. Optical communication modules need to be connected to other components through optical cables, and some centrally placed optical communication modules may require multiple optical cables.

[0003] A search of the China Patent Network (CN213750445U) reveals an optical communication module optical cable fixing device, comprising a mounting plate and multiple optical cable fixing assemblies mounted on the mounting plate. Each optical cable fixing assembly includes an outer ring and several first fixing members and second fixing members that can be mutually connected, mounted on the surface of the outer ring. A lower arc-shaped plate is fixed to the inner wall of the outer ring, and a movable arc plate is provided on the inner wall of the outer ring opposite to the lower arc plate. An outer shell is fixed to the movable arc plate, and a disc is fitted inside the outer shell. One end of a threaded rod is fixed to the top of the disc, and the other end of the threaded rod penetrates the side wall of the outer ring. A threaded sleeve is fitted onto the surface of the threaded rod and is fixed to the inner wall of the outer ring. This application has a reasonable structure; by adjusting the position of the first fixing members and second fixing members that can be interconnected, two or more optical cable fixing assemblies can be connected at any angle, accommodating optical cables distributed in any manner.

[0004] However, the above technical solutions have certain shortcomings. When the optical cable fixing device limits the optical cable, it uses a threaded rod to rotate in the inner cavity of the threaded sleeve, which drives the moving arc plate to move. The moving arc plate presses the optical cable onto the surface of the lower arc plate to fix the optical cable. However, the above technical solution only limits the optical cable in two opposite directions. When fixing multiple sets of optical cables, the optical cable often slips out from both sides of the limiting direction. Moreover, the optical cable is limited by hand-tightening two sets of threaded rods, which is laborious. Without professional tools, it is difficult to tighten the threaded rods to the designated position. Therefore, an optical communication module optical cable fixing device is proposed.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] An optical communication module optical cable fixing device, such as Figures 1 to 7 As shown, it includes an upper cover 700, a limiting ring 600 is assembled at the bottom end of the upper cover 700, a limiting member 400 is provided at the bottom end of the limiting ring 600, a drive gear ring 500 is installed at the top of the limiting member 400 around the limiting ring 600, a bottom shell 100 is assembled at the bottom end of the limiting member 400, a locking member 200 extending to the top is assembled inside the bottom shell 100, and a rotating ring 300 is connected to the outer wall of the locking member 200.

[0032] The number of limiting members 400 is six sets. The six sets of limiting members 400 are distributed in an equidistant array along the circumferential direction of the bottom shell 100. Each limiting member 400 includes a rack 410 that is slidably connected to the top of the bottom shell 100. An arc-shaped limiting plate 430 is fitted at the end of the rack 410. A limiting strip 420 is fixedly fitted on one side of the rack 410.

[0033] The bottom shell 100 includes a gear post 170 that meshes with the rack 410;

[0034] The inner wall of the drive gear ring 500 meshes with the outer wall of the gear column 170 via snap teeth;

[0035] During use, the operator passes the optical cable to be fixed through the main body of the device. Then, the operator rotates the limiting ring 600. The limiting ring 600 drives the locking component 200 to rotate through friction. After the locking component 200 rotates, it releases the locking of the drive gear ring 500. Then, the operator rotates the drive gear ring 500. The rotation of the drive gear ring 500 drives the gear column 170 to rotate, thereby driving the rack 410 to move. The movement of the rack 410 drives the arc-shaped limiting plate 430 to move. Since there are six sets of limiting components 400, the six sets of arc-shaped limiting plates 430 complete the limiting of the optical cable from different directions. Therefore, when fixing and limiting multiple sets of optical cables, the operation can be performed once to fix and limit the optical cable from multiple angles.

[0036] Please refer to this carefully. Figures 3 to 5 The bottom shell 100 also includes a base plate 110 mounted on the bottom end of the gear column 170. There are six sets of gear columns 170, which are equidistantly arranged along the circumference of the base plate 110. The gear columns 170 and the base plate 110 are rotatably connected by a rotating shaft. A second arc-shaped bracket 150 is mounted on the top of the base plate 110 near the center. A second limiting groove 160 is opened on the top of the second arc-shaped bracket 150. There are six sets of second arc-shaped brackets 150, which are equidistantly arranged along the circumference of the base plate 110.

[0037] A first arc-shaped retainer 130 is fitted at the top edge of the base plate 110. A first limiting groove 140 is provided at the top of the first arc-shaped retainer 130. There are six sets of first arc-shaped retainers 130. The six sets of first arc-shaped retainers 130 are distributed in an equidistant array along the circumference of the base plate 110. An annular groove 120 is provided on the top of the base plate 110 on the side of the first arc-shaped retainer 130 away from the first limiting groove 140. The gear column 170 is distributed in the middle area between the first arc-shaped retainer 130 and the second arc-shaped retainer 150. The internal space of the annular groove 120 matches the locking member 200.

[0038] Please refer to this carefully. Figure 3 , Figure 5 and Figure 7There are six sets of locking components 200, which are equidistantly arranged in an array along the circumference of the bottom shell 100. Each locking component 200 includes a sliding plate 210 that matches the annular groove 120. The top of the sliding plate 210 is fitted with a first threaded rod 220, which extends from the inside of the annular groove 120 to the top of the bottom plate 110. The outer wall of the first threaded rod 220 is provided with a first threaded sleeve 230, and the bottom ends of the first threaded sleeve 230 and the first threaded rod 220 are connected by threads. The inside of the first threaded sleeve 230 is fitted with a second threaded rod 240, and the top ends of the first threaded sleeve 230 and the second threaded rod 240 are connected by threads. The top end of the second threaded rod 240 is fitted with an abutment plate 250. The outer wall of the first threaded sleeve 230 is fitted with a frosted layer, the top end of the abutment plate 250 is fitted with a frosted layer, and the outer wall of the rotating ring 300 is provided with a frosted layer.

[0039] When the rotating ring 300 rotates, it drives the first threaded sleeve 230 to rotate through friction. The rotation of the first threaded sleeve 230 causes the first threaded rod 220 and the second threaded rod 240 to move longitudinally, thereby driving the abutment plate 250 to move longitudinally. When the abutment plate 250 is tightly fitted with the drive gear ring 500, the rotation of the drive gear ring 500 can be restricted.

[0040] Please refer to this carefully. Figures 1 to 5 The second limiting groove 160 and the first limiting groove 140 are located on the same plane. Both the second limiting groove 160 and the first limiting groove 140 limit the limiting member 400. The bottom end of the limiting ring 600 is provided with a third limiting groove that matches the top of the limiting member 400. The top end of the bottom shell 100 is provided with a fourth limiting groove that matches the bottom of the limiting member 400.

[0041] The axial position of the limiting member 400 is fixed by the first limiting groove 140, the second limiting groove 160, the third limiting groove and the fourth limiting groove, so that the limiting member 400 can only be displaced along the extension direction.

[0042] The parts of the device not covered herein are the same as or can be implemented using existing technologies.
