Description
Technical Field
[0001] This utility model relates to the field of end protection technology for optical fiber cables, and more specifically, it relates to an end protection component for optical fiber cables. Background Technology
[0002] The definition of optical fiber and optical cable can be divided into two parts: optical fiber and optical cable. The combination of the two constitutes the core transmission medium of modern communication. Optical fiber is a fibrous material made of glass or plastic that transmits light signals (light pulses) through the principle of total internal reflection. Optical cable is a composite cable composed of multiple optical fibers (usually containing multiple fiber bundles) plus a protective layer (such as a metal or plastic sheath), reinforcement (such as steel wire or fiber) and filler.
[0003] Fiber optic cable end protection components refer to devices or structures used to protect the ends of optical fibers or cables (such as fiber optic connectors, cable outlets, etc.) from physical damage, environmental erosion, or signal interference. They are usually installed at the exposed ends of optical fibers or cables to ensure the reliability and long-term stability of fiber optic connections.
[0004] Existing fiber optic cable end protection components typically use metal sleeves (such as stainless steel or aluminum alloy) to encase the fiber optic cable, thereby achieving a protective effect. However, when using metal sleeves, these existing end protection components usually only provide physical wrapping and generally lack internal stabilizing mechanisms such as clamps, adhesives, or slots. The fiber optic cable may experience slight displacement due to vibration, bending, or temperature changes, resulting in signal fluctuations.
[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes an end protection component for optical fiber cables. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an end protection component for optical fiber cables.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an end protection component for an optical fiber cable, comprising a lower protective shell and an upper protective shell;
[0008] The lower protective shell is provided with a first clamping mechanism for holding optical fiber cables.
[0009] The upper protective shell is provided with a second clamping mechanism, which is used to cooperate with the first clamping mechanism to clamp and fix the optical fiber cable.
[0010] The first clamping mechanism is provided with multiple limiting mechanisms for fixing the second clamping mechanism.
[0011] Preferably, the upper protective shell is slidably connected to the upper end of the lower protective shell, and the lower protective shell has multiple screw holes at its lower end. Multiple bolts are connected through the upper protective shell to facilitate the protection of the optical fiber cable.
[0012] Preferably, the first clamping mechanism includes a first support plate, a first clamping plate, a first protective pad, and a sliding groove. The first support plate is connected inside the lower protective shell, and multiple first clamping plates are equidistantly connected on the support plate. Each first clamping plate is connected to a first protective pad, and each first clamping plate has a sliding groove symmetrically opened at its upper end to facilitate the support of the optical fiber cable.
[0013] Preferably, each of the limiting mechanisms includes a limiting plate, a connecting plate, a spring, an inclined surface, a slide rail, and a connecting rod. Each of the first clamping plates is slidably connected to the limiting plate within the slide groove. One end of each limiting plate located outside the slide groove is connected to the connecting plate. Each connecting plate is connected to the first clamping plate via a spring. One end of each limiting plate located within the slide groove has a smooth inclined surface. The lower protective shell is symmetrically provided with multiple slide rails. The end of each connecting plate away from the spring extends into the corresponding slide rail. Each connecting plate located on the same side is connected via a connecting rod, which facilitates fixing the slider within the slide groove.
[0014] Preferably, the second clamping mechanism includes a second support plate, a second clamping plate, a slider, a second protective pad, and a limiting groove. The upper protective shell is connected to the second support plate, and multiple second clamping plates are equidistantly connected to the second support plate. Each second clamping plate has a slider symmetrically connected to its end away from the second support plate. Each second clamping plate has a second protective pad connected to it, and each slider has a limiting groove. Each slider can be slidably inserted into a corresponding groove, and each limiting plate can be slidably inserted into a corresponding limiting groove, so that each first clamping plate can cooperate with each second clamping plate to clamp and fix the optical fiber cable.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. In this utility model, by using a first clamping mechanism in the lower protective shell and a second clamping mechanism in the upper protective shell, when the upper protective shell is fixed on the lower protective shell, the slider on each second clamping plate will be inserted into the corresponding groove in the first clamping plate until each second clamping plate contacts each corresponding first clamping plate. At this time, each slider will be fully inserted into the corresponding groove, and each first clamping plate will close with each second clamping plate to clamp and fix the optical fiber cable. This solves the problem in the prior art where the end protection components of optical fiber cables use metal sleeves, which usually only provide physical wrapping and generally do not have internal clamps, adhesives, or slots for stabilization. The optical fiber cable will undergo slight displacement due to vibration, bending, or temperature changes, resulting in signal fluctuations.
[0017] 2. In this utility model, by setting a limiting mechanism on each first clamping plate, when each slider enters the corresponding slide groove, each downward-moving slider will contact the corresponding limiting plate. At the same time, each slider will press down on the smooth inclined surface of each limiting plate and move downward. When each slider moves downward, it will press the limiting plate to move outward and stretch the connected spring until the limiting plate is flush with the limiting groove on the slider. At this time, each stretched spring will push each limiting plate into the corresponding limiting groove through its elasticity, thereby fixing the slider in the corresponding slide groove. It can effectively form a mechanical lock by inserting the limiting plate into the limiting groove, thereby preventing the slider from falling out of the slide groove due to external force.

[0027] like Figure 1-7 As shown, this utility model provides an end protection component for optical fiber cables, including a lower protective shell 1 and an upper protective shell 2. The upper protective shell 2 works in conjunction with the lower protective shell 1 to protect the optical fiber cable. The upper protective shell 2 is slidably connected to the upper end of the lower protective shell 1, and multiple screw holes 7 are provided at the lower end of the lower protective shell 1. Multiple bolts 6 are connected through the upper protective shell 2, which are used to close and open the upper protective shell 2 and the lower protective shell 1 through the bolts 6.
[0028] The lower protective shell 1 is provided with a first clamping mechanism 3 for placing the optical fiber cable, and the upper protective shell 2 is provided with a second clamping mechanism 5 for clamping and fixing the optical fiber cable in conjunction with the first clamping mechanism 3. The second clamping mechanism 5 is used to fix the upper protective shell 2 on the lower protective shell 1. At this time, the slider 503 on each second clamping plate 502 will be inserted into the corresponding groove 304 in the first clamping plate 302 until each second clamping plate 502 contacts each corresponding first clamping plate 302. At this time, each slider 503 will be fully inserted into the corresponding groove 304. Then, each first clamping plate 302 and each second clamping plate 502 will close together to clamp and fix the optical fiber cable. This can effectively prevent the optical fiber cable from shaking in the closed space formed by the upper protective shell 2 and the lower protective shell 1, thereby improving the stability of the optical fiber cable.
[0029] The first clamping mechanism 3 includes a first support plate 301, a first clamping plate 302, a first protective pad 303, and a sliding groove 304. The first support plate 301 is connected inside the lower protective shell 1. Multiple first clamping plates 302 are equidistantly connected on the support plate, which are used to place optical fiber cables. Each first clamping plate 302 is connected to a first protective pad 303, which is used to increase the friction between the optical fiber cable and the first clamping plate 302, and can also protect the optical fiber cable. Each first clamping plate 302 has a sliding groove 304 symmetrically opened at the upper end.
[0030] The second clamping mechanism 5 includes a second support plate 501, a second clamping plate 502, a slider 503, a second protective pad 504, and a limiting groove 505. The second support plate 501 is connected inside the upper protective shell 2. Multiple second clamping plates 502 are equidistantly connected to the second support plate 501, which are used to achieve clamping and fixing of the optical fiber cable by contacting the first clamping plate 302 through each second clamping plate 502. A slider 503 is symmetrically connected to the end of each second clamping plate 502 away from the second support plate 501, which is used to realize insertion... The first clamping plate 302 and the second clamping plate 502 are connected to the corresponding sliding groove 304 to improve the stability of the contact between them. Each second clamping plate 502 is connected to a second protective pad 504, which is used to increase the friction between the optical fiber cable and each second clamping plate 502 and to protect the optical fiber cable. Each slider 503 is provided with a limiting groove 505, and each slider 503 can be slidably inserted into the corresponding sliding groove 304. Each limiting plate 401 can be slidably inserted into the corresponding limiting groove 505.
[0031] The first clamping mechanism 3 is provided with multiple limiting mechanisms 4 for fixing the second clamping mechanism 5. When each slider 503 enters the corresponding groove 304, each downward-moving slider 503 will contact the corresponding limiting plate 401. At the same time, each slider 503 will press down on the smooth inclined surface 404 of each limiting plate 401 and move downward. When each slider 503 moves downward, it will press the limiting plate 401 to move outward and stretch the connected spring 403 until the limiting plate 401 is flush with the limiting groove 505 opened on the slider 503. At this time, each stretched spring 403 will push each limiting plate 401 into the corresponding limiting groove 505 through its elasticity, thereby fixing the slider 503 in the corresponding groove 304. It can effectively form a mechanical lock by inserting the limiting plate 401 into the limiting groove 505, thereby preventing the slider 503 from falling out of the groove 304 due to external force.
[0032] Each limiting mechanism 4 includes a limiting plate 401, a connecting plate 402, a spring 403, an inclined surface 404, a slide rail 405, and a connecting rod 406. Each first clamping plate 302 is located within a slide groove 304 and is slidably connected to the limiting plate 401. This allows each limiting plate 401 to be inserted into a corresponding limiting groove 505, thereby fixing each slider 503 within the corresponding slide groove 304. One end of each limiting plate 401 located outside the slide groove 304 is connected to a connecting plate 402, which facilitates the operator's grip. Each connecting plate 402 is connected to the first clamping plate 302 via a spring 403, which enables each limiting plate 401 to... It has a vibration reset function and can also fix the limiting plate 401 in the limiting groove 505. One end of each limiting plate 401 located in the slide groove 304 is a smooth inclined surface 404, which is used to reduce friction when the slider 503 is pressed down, so as to move the limiting plate 401 outward. The lower protective shell 1 is symmetrically provided with multiple slide rails 405, which are used to facilitate the sliding of each connecting plate 402. The end of each connecting plate 402 away from the spring 403 extends into the corresponding slide rail 405, and each connecting plate 402 located on the same side is connected by a connecting rod 406, which is used to facilitate the synchronous movement of each connecting plate 402 on the same side.
[0033] Working principle: When it is necessary to protect and stabilize the optical fiber cable, the optical fiber cable is first placed on each first clamp plate 302. Then, the upper protective shell 2 is brought into contact with the lower protective shell 1. At this time, each bolt 6 on the upper protective shell 2 will be inserted into the corresponding screw hole 7. Then, by rotating the bolt 6, the upper protective shell 2 is fixed on the lower protective shell 1.
[0034] When the upper protective shell 2 is fixed on the lower protective shell 1, the slider 503 on each second clamping plate 502 will be inserted into the groove 304 in the corresponding first clamping plate 302 until each second clamping plate 502 contacts each corresponding first clamping plate 302. At this time, each slider 503 will be fully inserted into the corresponding groove 304, and each first clamping plate 302 will close with each second clamping plate 502 to clamp and fix the optical fiber cable.
[0035] When each slider 503 enters the corresponding groove 304, each downward-moving slider 503 will contact the corresponding limiting plate 401. At the same time, each slider 503 will press down on the smooth inclined surface 404 of each limiting plate 401 and move downward. When each slider 503 moves downward, it will press the limiting plate 401 to move outward and stretch the connected spring 403 until the limiting plate 401 is flush with the limiting groove 505 opened on the slider 503. At this time, each stretched spring 403 will use its elasticity to insert each limiting plate 401 into the corresponding limiting groove 505, thereby fixing the slider 503 in the corresponding groove 304.
[0036] When it is necessary to remove the optical fiber cable, first loosen each bolt 6, then grasp the connecting rods 406 on both sides and move them misaligned. When the two connecting rods 406 move, each connecting plate 402 will move within the corresponding slide rail 405. When each connecting plate 402 moves, the connected limiting plate 401 will slowly disengage from the limiting groove 505, and at the same time, each connected spring 403 will be stretched until each limiting plate 401 disengages from the corresponding limiting groove 505. Then, remove the upper protective shell 2, and then remove the optical fiber cable from each first clamp 302.

Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
