The invention belongs to the technical field of cable joints, and particularly relates to a disc cabinet cable sealing joint, a main body structure comprises an inner sealing ring and an outer sealing ring connected with the inner sealing ring through a
threaded pipe, and the disc cabinet cable sealing joint comprises the inner sealing ring, the
threaded pipe, the outer sealing ring, an interface and a through hole, an interface is arranged in the center of the inner sealing ring, a through hole is formed in the center of the outer sealing ring, a novel and reasonable double-film sealing structure is adopted, after a cable penetrates in from the interface and penetrates out from the through hole, the interface and the through hole are tightly attached to the cable based on the specific self-tightening characteristic of TPU (
thermoplastic polyurethane elastomer) materials, and the cable sealing device has double protection levels and is convenient to use. The sealing performance and the waterproof and dustproof performance are guaranteed, the
threaded pipe of a multi-ring structure is suitable for plate cabinet box bodies of various thicknesses, and the protection level of the connecting position of the threaded
pipe and the box body can be guaranteed; the structure is simple, the installation is convenient, the threading is convenient, the wiring cost is reduced, and the waterproof and dustproof effects of the plate cabinet are improved.
