Problems solved by technology
[0004] 1. The use of some materials of structural parts in harsh environments (high temperature, high humidity or low temperature) is controversial, and there have been water ingress and corrosion of cable joints caused by unstable material properties in harsh environments, which have caused signal failures ;
[0005] 2. The complex structure of the joint sheath is not conducive to long-term repeated opening and closing, and the production process is complicated and the cost is too high

Embodiment 1
[0024] Such as figure 1 As shown, a cable joint sealing waterproof sheath includes a fixed end silicone rubber plug 1 and a sliding end silicone rubber sleeve 5,
[0025] The fixed-end silicone rubber plug 1 is in the shape of a hollow step, which is sleeved on the fixed end of the cable joint, including a base and a raised boss on the base. The outer wall of the boss is provided with a groove structure to form a groove structure for damping surface 3, the base plane connected with the damping surface 6 of the groove structure is the flange sealing surface a2.
[0026] One end of the sliding end silicone rubber sleeve 5 is flaring, and the other end is shrinking, and one end of the shrinking shape is provided with a high resilience silicone rubber ring 6, and the inner diameter of the high resilience silicone rubber ring 6 is the same as the The outer diameter of the cable at the fixed end matches, and the flared end is set on the silicone rubber plug at the fixed end, and th...

The invention relates to a sealing and waterproof sheath for a cable joint, comprising a fixed-end silicone rubber plug and a sliding-end silicone rubber sleeve. The fixed-end silicone rubber plug is provided with a flange sealing surface a and a groove structure damping surface. The sliding end silicone rubber sleeve is provided with a flange sealing surface b and a high resilience silicone rubber ring, the fixed end silicone rubber plug is assembled on the fixed end of the cable joint, and the sliding end silicone rubber sleeve is assembled on the non- When the fixed end is connected, the flange sealing surface a and flange sealing surface b are sealed and connected, and the groove structure damping surface is inserted into the sliding end silicone rubber sleeve for connection and fixation, and forms a second layer of sealed waterproof surface. The high-resilience silicone rubber ring is closely attached to the cable at the non-fixed end. Compared with the prior art, the invention has the advantages of good sealing and waterproof performance, good weather resistance, convenient loading and unloading, and the like.
Description
technical field [0001] The invention relates to a cable joint, in particular to a cable joint sealing and waterproof sheath. Background technique [0002] With the development of the communication industry, the requirements for sealing and waterproof performance of cable joints in various environments are getting higher and higher. The sealing and waterproofing of cable joints directly affect the stability of cable signal transmission. Therefore, The sealing and waterproof reliability of the cable joint sheath used will effectively guarantee the long-term and stable use of the cable joint under various complex outdoor environmental conditions. At the same time, in order to facilitate the installation and maintenance of the engineering site, the convenience of loading and unloading and reusability of the sealed waterproof sheath will facilitate the operation and maintenance of the site. [0003] At present, the cable joint sheath commonly used in the market has the following...
