Description

Technical Field

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

[0002] Optical fiber cable is a cable made of single-core or multi-core optical fiber that meets optical, mechanical and environmental characteristics. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as the transmission medium and can be used alone or in groups. The basic structure generally consists of cable core, reinforcing steel wire, filler and sheath, etc., and may also include waterproof layer, buffer layer, etc. as needed. Optical fiber cable often needs to be spliced ​​by two optical fiber cable joints during use.

[0003] To address this, China Patent Network published an application with application number 202320126326.3 for a fiber optic cable splice. The splice features a cutting edge formed on the tangential surfaces of the fiber optic convex and concave connectors. This cutting edge allows for the cutting of the protruding fiber optic cable while the mortise and tenon structure is interlocked, improving connection convenience. The splice includes a male connector installed at one end of one fiber optic cable and a female connector installed at the other. The male connector comprises a fiber optic convex connector and a cable clamping and fixing device A connected together. The female connector comprises a fiber optic concave connector and a cable clamping and fixing device B connected together. The fiber optic convex and concave connectors form a mortise and tenon structure that interlocks with each other. The two fiber optic cables are clamped and fixed by the cable clamping and fixing devices A and B respectively, and then aligned and wedge-connected using the mortise and tenon structure of the fiber optic convex and concave connectors. No connector head or fiber stripping is required, making the connection relatively convenient.

[0004] Although the above-mentioned applications meet the user's needs to a certain extent, there are still some defects in the use process. The specific problems are as follows: Since the optical cable body is composed of multiple branches tightly combined to ensure the efficient and stable operation of the optical cable, if the optical cable joints are messy, it will affect the connection effect of the optical cable body and may also cause problems such as signal attenuation and unstable transmission at the connection point. Based on this, this utility model designs an optical cable joint splicing device to solve the above problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 The present invention provides a technical solution: an optical cable connector splicing device, comprising two optical cable bodies 1, and a connection sealing component 2 installed on the outer side of the optical cable body 1. The connection sealing component 2 includes an installation cylinder 201, a fixing rod 202, a sleeve 203, a limiting block 204 and an abutment plate 206.

[0030] An installation cylinder 201 is movably sleeved on the outside of an optical cable body 1. Several wiring grooves are opened inside the installation cylinder 201 and the abutment plate 206 to facilitate the arrangement of the branches inside the optical cable body 1 and to facilitate the docking of the corresponding branches, so as to ensure the smooth progress of the docking work and the stable operation of the optical cable transmission system. A fixing rod 202 is fixedly connected inside the installation cylinder 201. Several limiting blocks 204 are fixedly connected at equal intervals on the outside of the fixing rod 202. A sleeve 203 is fixedly connected inside the installation cylinder 201. The abutment plate 206 is slidably connected inside the installation cylinder 201.

[0031] The protective and anti-seismic component 3 is installed on the outside of the mounting cylinder 201. The protective and anti-seismic component 3 includes a damper 301, a slider 302, a movable frame 303, and a mounting groove 307.

[0032] The mounting cylinder 201 has symmetrically opened mounting grooves 307 inside. Two dampers 301 are fixedly connected inside the mounting groove 307, and a slider 302 and a moving frame 303 are slidably connected inside the mounting groove 307.

[0033] The connecting sealing assembly 2 also includes a limiting spring 205, a connecting cylinder 207, a first arc plate 208, a second arc plate 209, a mounting block 210, and a fixing bracket 211;

[0034] Limiting springs 205 are fixedly connected to one side of both sleeve 203 and fixing rod 202. A connecting cylinder 207 is movably sleeved on the outer side of another optical cable body 1. Anti-slip rubber rings are fixedly connected to one side of both connecting cylinder 207 and mounting cylinder 201 to facilitate fixing to the outer side of optical cable body 1. A second arc plate 209 is fixedly connected to one side of connecting cylinder 207. A first arc plate 208 is rotatably connected to one side of the second arc plate 209. Mounting blocks 210 are fixedly connected to one side of both the first arc plate 208 and the second arc plate 209. The two mounting blocks 210 are fixedly connected by bolts to facilitate fixing the first arc plate 208 and the second arc plate 209, ensuring the sealing of the connection and preventing rainwater erosion. At the same time, it can also play a role in dust prevention. A fixing bracket 211 is fixedly connected to the bottom end of connecting cylinder 207. A fixing bolt is connected to the internal thread of fixing bracket 211.

[0035] The mounting cylinder 201 and connecting cylinder 207 are respectively fitted onto the outside of the two optical cable bodies 1. The branches inside the optical cable body 1 are passed through the wiring groove. The branches are guided by the limiting block 204 to keep them pushed in the same horizontal direction. Pressing the abutment plate 206, the abutment plate 206 compresses the limiting spring 205, making it easier for the branches to pass through the wiring groove inside the abutment plate 206. Similarly, the optical cable body 1 inside the connecting cylinder 207 is branched and arranged, and the connecting cylinder 207 is connected to the abutment plate 206. At this time, the connecting cylinder 207 is fitted onto the outside of the mounting cylinder 201. The abutment plate 206, which has lost pressure, is reset by the limiting spring 205 and the connecting cylinder 201 is closed. The internal optical cable body 1 is connected to ensure the connection effect of the two optical cable bodies 1. The first arc plate 208 is rotated to make the first arc plate 208 fit with the second arc plate 209. The two mounting blocks 210 are fixed by bolts. The fixed connection is made on the outside of the mounting cylinder 201 rather than at the connection between the mounting cylinder 201 and the connecting cylinder 207. This ensures the sealing of the connection between the mounting cylinder 201 and the connecting cylinder 207, avoids the corrosion of rainwater and dust, and extends the service life of the optical cable body 1. The cooperation between the fixing bracket 211 and the fixing bolt allows the spliced ​​optical cable body 1 to be installed on the wall or other planes, improving its performance.

[0036] The protective and seismic component 3 also includes a connecting frame 304, a protective plate 305, and a mounting frame 306;

[0037] The movable frame 303 is rotatably connected to a connecting frame 304. One end of the connecting frame 304 is rotatably connected to a mounting frame 306. The top of the mounting frame 306 is fixedly connected to a protective plate 305. The protective plate 305 is annular, which facilitates the protection of the mounting cylinder 201 and avoids damage to the mounting cylinder 201 by external impact forces, thus affecting the use effect of the mounting cylinder 201.

[0038] When subjected to external impact, the connecting cylinder 207 can protect the mounting cylinder 201. At the same time, the protective plate 305 is subjected to force, and the protective plate 305 transmits the impact force to the mounting frame 306. The mounting frame 306 causes the connecting frame 304 to rotate, and drives the moving frame 303 to move inside the mounting groove 307. When the moving frame 303 moves, it pushes the slider 302 to slide closer to the damper 301, so that the impact force is transmitted to the damper 301. The damper 301 can cancel out the impact force, thereby playing a shock absorption role, ensuring the performance of the mounting cylinder 201, and further extending the service life of the optical cable body 1.
