Description

Technical Field

[0001] The present invention relates to the technical field of outdoor optical cables, and in particular to an outdoor optical cable that is easy to connect quickly. Background Art

[0002] Outdoor optical cable, simply put, is an optical cable used outdoors. It is a type of optical cable. It is called outdoor optical cable because it is most suitable for use outdoors. It is durable, can withstand wind, sun, cold weather, has a thick outer packaging, and has some mechanical and environmental properties such as pressure resistance, corrosion resistance, and tensile resistance. Optical cables are widely used in the fields of communications, radio and television, enterprise networks, finance, and transportation, bringing great convenience to people's daily life and work.

[0003] After searching, the Chinese patent authorization number CN209821452U discloses an optical cable that can be quickly installed at the connection point, and discloses that the second joint is connected to the cable at one end away from the first joint, and the cable is electrically connected to the second joint. A hard plastic ring is arranged on the outer side of the front end of the second joint, and the hard plastic ring is welded to the front end of the second joint. A baffle is arranged on the rear end of the second joint, and the baffle is welded to the end of the second joint. A fixing sleeve is arranged on the outer side of the second joint, and a thread is arranged on the inner side of the fixing sleeve. The fixing sleeve is rotatably connected to the thread ring through the thread. A conductive column is arranged on the front end of the second joint, and the conductive column is electrically connected to the cable. The conductive column is inserted into the conductive slot, and a cavity is arranged inside the second joint, and the cavity is filled with heat-absorbing filler. The above patent has the following deficiencies: the existing outdoor optical cables generally achieve the effect of extending the optical cable by connecting two sections of optical cables. However, the existing optical cables are usually connected by threads when connected. This connection method has great disadvantages. Since most outdoor optical cables are usually installed outdoors, especially in some areas with frequent windy and rainy weather or dusty areas, there are also some optical cables used for field communications. Although traditional threaded connections and snap-on connections can be connected, they do not have the effect of sealing the inside of the cable. It is inevitable that some rainwater, dirt and other impurities will enter the connection, resulting in unstable internal optical cable connection signals, resulting in unstable communication transmission. Moreover, the threaded surface will rust due to long-term erosion by rainwater and cannot be quickly disassembled. In the process of transporting the optical cable, some dust may stick to the surface of the optical cable connector, which generally needs to be cleaned manually, and cannot be quickly connected, affecting the connection speed of the optical cable.
