They are communication cable assemblies that use one or more optical fibers encased in a sheath as the transmission medium and can be used individually or in groups. An optical fiber cable is a communication line that uses a certain number of optical fibers arranged in a specific way to form a cable core, encased in a sheath, and sometimes covered with an outer protective layer, to enable the transmission of optical signals.
[0003] The utility model patent CN218886246U relates to the field of optical cable connection technology and discloses a quick-connect optical cable connector, including a U-shaped plate with a separator block fixedly connected to the inner wall of the U-shaped plate. In this utility model, after the optical fiber filament is fixed to the connector, two sections of the optical cable body are connected together through the optical fiber sheet, thus allowing the user to quickly connect the two sections of the optical cable body together.
[0004] When laying optical fibers, multiple optical cable segments need to be connected together. Although the connector in the aforementioned patent is convenient for connecting the two ends of the optical fiber, the two ends of the optical fiber need to be connected through a connecting piece. However, the connecting piece will cause optical signal reduction, increase the loss at the optical fiber connection, and reduce the optical fiber transmission effect. To solve the above problems, we provide a quick connection device for emergency optical cables for communication. Utility Model Content

This emergency optical cable quick connection device for communication uses limiting blocks and limiting grooves to position the connection plate, preventing misalignment of the optical cable connection and improving the stability and accuracy of the connection. A limiting ring positions the positioning sleeve, improving its rotational stability.

[0026] This utility model provides a quick connection device for emergency optical cables used in communication.
[0027] Please see Figure 1 and Figure 2 It includes an optical cable 1, which has a fixed steel cable 11 and an optical fiber 12 inside. The fixed steel cable 11 is used to reinforce the optical cable 1 and improve its tensile strength. The optical signal is transmitted through the optical fiber 12.
[0028] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 Two optical cables 1 are each equipped with a docking mechanism 2 at one end close to each other. The docking mechanism 2 includes a fixed housing 201 and a connecting plate 202. A fixed tube 203 and a connector 204 are fixedly connected to the surface of the connecting plate 202. The two connectors 204 are fixedly connected to the two optical fibers 12. By bringing the two connectors 204 close to each other, the two optical fibers 12 are connected together at their closest points, thereby connecting the two optical cables 1 together. The docking of the two optical fibers 12 reduces the attenuation of the optical signal and improves the stability of optical fiber transmission. The fixed tube 203 is fixedly connected to the fixed steel cable 11, connecting the optical cable 1 to the docking mechanism 2, reinforcing the connection and improving the stability of the optical cable connection.
[0029] The fixing tube 203 is fixedly connected to the surface of the fixing steel cable 11, and the connector 204 is fixedly connected to the surface of the optical fiber 12. The two connectors 204 are connected by mutual contact. One connector 204 is a conical protrusion and the other is a conical groove. The two optical fibers 12 are physically connected by inserting the conical protrusion into the conical groove, which improves the stability of the connection of the optical fiber 12. When the cable leaves the factory, the connection and encapsulation of the optical cable 1 and the connecting plate 202 are completed. On site, only the two fixing shells 201 need to be connected. It can adapt to the field environment without electricity and improve the efficiency of optical cable connection.
[0030] The fixing tube 203 and the connector 204 are both slidably connected to the fixing housing 201. The fixing housing 201 is fixedly connected to the outer surface of the optical cable 1. The fixing housing 201 is used to fix the fixing tube 203 and the connector 204. The fixing housing 201 is used to seal and fix the terminal of the optical cable 1, thereby improving the stability of the cable connection. After the cable connection is completed, it can be fixed by epoxy resin potting, which improves the stability and sealing of the connection between the fixing housing 201 and the optical cable 1.
[0031] A limiting groove 205 is provided at the top of the connecting plate 202, and a limiting block 206 is fixedly connected inside the fixed housing 201. The limiting block 206 is slidably connected to the limiting groove 205. The position of the connecting plate 202 is positioned by the limiting block 206 and the limiting groove 205 to avoid misalignment of the optical cable connection and improve the stability and accuracy of the optical cable connection.
[0032] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 A fixing mechanism 3 is provided at the connection of the two fixed housings 201. The fixing mechanism 3 includes a positioning sleeve 301, a positioning rod 303 and a sealing ring 306. The positioning sleeve 301 and the positioning rod 303 reinforce the connection of the two fixed housings 201 and improve the stability of the optical cable 1 connection.
[0033] The two sides of the sealing ring 306 abut against the two fixed housings 201. The sealing ring 306 seals the connection between the two fixed housings 201, preventing external moisture and impurities from entering the device and causing corrosion of the optical cable, thereby improving the stability of the optical cable connection and extending the service life of the optical cable.
[0034] A limiting ring 302 is slidably connected to the middle of the positioning sleeve 301, and the inner ring of the limiting ring 302 is fixedly connected to a fixed outer shell 201. The positioning rod 303 is fixedly connected to another fixed outer shell 201. The positioning sleeve 301 is positioned by the limiting ring 302, thereby improving the stability of the rotation of the positioning sleeve 301.
[0035] The positioning sleeve 301 has a sliding groove 304 inside. The positioning rod 303 is slidably connected to the sliding groove 304. The sliding groove 304 has a limiting pad 305 that limits the positioning rod 303. The sliding groove 304 is wide at one end and narrow at the other. By rotating the positioning sleeve 301, the positioning rod 303 slides in the sliding groove 304, bringing the two fixed shells 201 closer to each other and completing the connection of the two optical cables 1.
[0036] A circular insertion rod 307 and a square insertion rod 308 are fixedly connected to the surface of the fixed housing 201, and both the circular insertion rod 307 and the square insertion rod 308 are inserted into another fixed housing 201. The circular insertion rod 307 and the square insertion rod 308 are used to position the connection position of the two fixed housings 201, thereby improving the accuracy of the fiber optic cable 12 splicing.
[0037] Working principle: First, the fixed steel cable 11 is threaded into the fixed tube 203. According to the length value of the connector 204, the optical fiber 12 is cut to the corresponding length and threaded into the connector 204. The fixed steel cable 11 and the fixed tube 203 are fixed together by the hydraulic device. Then, the connecting plate 202 is connected to the fixed housing 201 by the limiting block 206 and the limiting groove 205. The fixed housing 201 is then placed on the outside of the optical cable 1. Epoxy resin is then injected into the fixed housing 201 to fix the fixed housing 201 to the optical cable 1. The optical fiber 12 is connected to the connector 204. The sealing ring 306 is placed on the surface of one fixed housing 201. The round insert 307 and the square insert 308 are inserted into the corresponding groove of the other fixed housing 201 to complete the connection of the two fixed housings 201.
[0038] The connection between the two fixed housings 201 is sealed by the sealing ring 306. At the same time, the positioning rod 303 enters the sliding groove 304. The positioning sleeve 301 is rotated to make the positioning rod 303 slide in the sliding groove 304, bringing the two fixed housings 201 closer together and completing the connection of the two optical cables 1. The position of the positioning rod 303 is fixed by the limiting pad 305. After the connection is completed, epoxy resin is injected into the sliding groove 304 to encapsulate the device and improve the sealing of the docking device. After encapsulation, an EVA foam buffer layer is wrapped around the fixed housings 201 and the positioning sleeve 301 to increase the impact resistance of the optical cable connection. Through the above devices, the attenuation of the optical signal is reduced and the stability of optical fiber transmission is improved.
