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 hollow and step-shaped, and 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, and 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 in the shape of a flaring mouth, and the other end is in a shrinking shape, and one end in the shape of a lock 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 that of the The outer diameter of the cable at the fixed end matches, and the flared end is set on the silicon...

The invention relates to a sealing and water-proofing sheath for a cable connector. The sealing and water-proofing sheath comprises 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 arranged at the fixed end of the cable connector, and the sliding-end silicone rubber sleeve is arranged at the non-fixed end of the cable connector. During connection, the flange sealing surface a is connected with the flange sealing surface b in a sealing mode, the groove structure damping surface is inserted in the sliding-end silicone rubber sleeve in a fixedly connected mode, a second sealing and water-proofing surface layer is formed, and the high-resilience silicone rubber ring is tightly attached to a cable at the non-fixed end. Compared with the prior art, the sealing and water-proofing sheath for the cable connector has the advantages of being good in sealing and water-proofing performance, good in weather resistance, convenient to mount and demount 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...
