[0002] Optical fiber and fiber optic patch cables are both important components used in optical communications technology. Optical fiber is the transmission medium for light signals, while fiber optic patch cables are essential tools for connecting different fiber-optic devices. They play a vital role in modern communications and network systems and are widely used in data centers, telecommunications networks, local area networks, and other applications.

[0003] In modern communication networks, high-quality connection structures must not only ensure reliable connections between optical fibers and fiber optic patch cords to achieve efficient network signal transmission, but also have good stability and durability.

[0004] However, the existing optical fiber and optical fiber jumper connection structure has some shortcomings: on the one hand, many connection structures lack effective protection measures for the hot melt connection, and when subjected to a certain degree of external force, the hot melt connection is easily broken, increasing the incidence of network failures. On the other hand, some integrated fixed connection structures cannot be disassembled after being installed on the outside of the optical fiber and jumper. When the optical fiber is damaged, its connection structure will also be discarded, causing waste. Therefore, a connection structure between optical fiber and optical fiber jumper is proposed to solve the above problems. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a connection structure of an optical fiber and an optical fiber jumper, comprising a lower connecting seat 1, the top of the lower connecting seat 1 is rotatably connected to the upper connecting seat 3 through a limit assembly 2, and the upper connecting seat 3 is rotatable to open with the lower connecting seat 1 by providing modularity, so that after the optical fiber is damaged, the entirety can be disassembled for secondary use, and a positioning mechanism 4 is provided on the inner wall of the top of the upper connecting seat 3. The left inner wall of the lower connecting seat 1 is detachably mounted with an optical fiber 5, and the right inner wall of the lower connecting seat 1 is detachably mounted with an optical fiber jumper 6. The optical fiber 5 and the optical fiber jumper 6 are fixedly connected by hot melting. The optical fiber 5 and the optical fiber jumper 6 are both existing technologies. The optical fiber 5 and the optical fiber jumper 6 are hot-melt connected by a hot-melt machine, so that network signals can be transmitted.

[0035] Reference Figure 3 - Figure 5 The positioning mechanism 4 includes a slider 41, and a slide groove is provided at the top of the upper connecting seat 3. The slider 41 is slidably connected to the inner wall of the slide groove at the top of the upper connecting seat 3. A connecting block is provided on the outer side of the slider 41, so that when not in use, the slide groove at the top of the upper connecting seat 3 can be covered to prevent dust and water from entering the interior of the upper connecting seat 3, thereby causing corrosion to the optical fiber 5. The outer walls of both sides of the slider 41 are hinged with hinge rods 43, and the hinge rod 43 is hinged with a positioning seat 44 at one end away from the slider 41. When the slider 41 moves, the two sets of hinge rods 43 will pull the corresponding positioning seats 44 closer to each other, so that the two sides of the connection between the optical fiber 5 and the optical fiber jumper 6 after the hot melt connection can be pressed tightly to prevent the hot melt connection from being weak. When it is pulled by external force, the hot melt will break. The material used by the positioning seat 44 is rubber material, which contacts the outer walls of the optical fiber 5 and the optical fiber jumper 6, thereby increasing friction and preventing the hot melt connection from breaking due to pulling.

[0036] Reference Figure 4 and Figure 5The top of the inner side of the upper connecting seat 3 is provided with a slide groove, and the top of the outer wall of the positioning seat 44 is slidably connected to the inner wall of the slide groove. By providing a slide groove at the top of the inner side of the upper connecting seat 3, the position of the positioning seat 44 can be guided so that it can only move longitudinally, so that optical fibers 5 of different thicknesses can be adjusted and pressed. The inner wall of the top of the slider 41 is elastically connected to the plug 42 through a limit spring 45, and the hinged rod 43 is slidably connected to the inner wall of the top of the upper connecting seat 3. One end of the limit spring 45 is fixedly connected to the outer wall of the bottom end of the plug 42, and the other end of the limit spring 45 is fixedly connected to the outer wall of the bottom end of the plug 42. The end is fixedly connected to the inner wall of the slider 41, and the function of the limit spring 45 is to automatically reset the position of the plug block 42 after it is pulled outward. The limit spring 45 passes through and is slidably connected to the inner wall of the top of the slider 41. The outer wall of the positioning seat 44 contacts the outer wall of the optical fiber 5. The side wall of the top slide of the upper connecting seat 3 is provided with multiple groups of through holes, and the bottom end of the outer wall of the plug block 42 is plugged into the inner wall of the through hole. The plugging between the two can drive the slider 41 to drive the hinged rod 43 to pull the corresponding positioning seat 44 to adjust and tighten the optical fibers 5 of different thicknesses for fixing.

[0037] Reference Figure 2 and Figure 4 - Figure 6 The limit assembly 2 includes an insertion rod 21, and the outer wall of the top of the insertion rod 21 is fixedly connected to a guide block 22. The guide block 22 is elastically connected to the outer side wall of the upper connecting seat 3 through a return spring 23. One end of the return spring 23 is fixedly connected to the outer wall of the guide block 22, and the other end of the return spring 23 is fixedly connected to the outer side wall of the upper connecting seat 3. The function of the return spring 23 is to automatically reset the position of the guide block 22 after following the insertion rod 21 to be pulled outward. The guide block 22 is slidably connected to the outer side wall of the upper connecting seat 3, and the inner side wall of the upper connecting seat 3 A guide groove that fits the guide block 22 is provided on the side, so that the insertion rod 21 drives the guide block 22 to be pulled outward in a straight line. A through hole is provided on the top surface of the lower connecting seat 1, and the bottom end of the outer wall of the insertion rod 21 is plugged into the inner wall of the through hole. The plugging between the two can rotate the upper connecting seat 3 to fit the position of the lower connecting seat 1 and close it, thereby avoiding the upper connecting seat 3 from rotating during daily use. At the same time, through modular design, the optical fiber 5 can be disassembled as a whole for secondary use when it is damaged.

[0038] When the upper connecting seat 3 is in the closed position, the guide block 22 is released, and the guide block 22 is reset under the elastic action of the reset spring 23, and the rod 21 is reinserted into the through hole at the top of the lower connecting seat 1, fixing the upper connecting seat 3 in the closed position. This can prevent the upper connecting seat 3 from rotating during daily use. At the same time, this modular design makes it convenient to disassemble and reuse the overall structure when the optical fiber 5 is damaged.

[0039] At this time, the plug block 42 can be toggled and the limit spring 45 can be elastically compressed. At the same time, the bottom end of the plug block 42 will also be out of the through hole at the current position of the upper connecting seat 3. At this time, by moving the slider 41, the slider 41 is moving. Since the hinged rods 43 are hinged on both sides, the hinged rods 43 will pull the corresponding positioning seat 44 to move. Because the top of the outer wall of the positioning seat 44 slides in the slide groove at the top inner side of the upper connecting seat 3, the slide groove guides the moving direction of the positioning seat 44, so that the positioning seat 44 can only move longitudinally. When the slider 41 moves, the two groups of positioning seats 44 move closer to each other, After connection, the optical fiber 5 and the optical fiber jumper 6 are tightened on both sides of the connection. The positioning seat 44 is made of rubber material. When it contacts the outer wall of the optical fiber 5 and the optical fiber jumper 6, it can increase the friction force, further enhance the fixing effect of the connection, and effectively prevent the hot melt from breaking due to excessive force when pulled by external force. When the slider 41 is released, the limit spring 45 automatically resets, and the plug 42 is inserted into the through hole to fix the position of the slider 41 and the positioning seat 44 driven by the hinged rod 43, so that the positioning seat 44 can be adjusted and tightened according to the different thicknesses of the optical fiber 5 and maintain a fixed state.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
