Cabinet cable sealing joint

Abstract

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.

Description

Technical field: [0001] The invention belongs to the technical field of cable joints, and in particular relates to a cable sealing joint of a panel cabinet, which can quickly connect cables and has a double waterproof sealing structure. Background technique: [0002] The cable joint, also known as the cable head, is used to lock and fix the incoming and outgoing wires, play the role of waterproof, dustproof and anti-vibration, make the line unobstructed, keep the cable sealed, and ensure the insulation level at the cable joint to make it safe and reliable. run. Most of the commonly used panel cable glands use the lock nut to match the tapered thread. After the connector is fixed on the panel, loosen the lock nut, put on the cable, tighten the nut to squeeze the inner sealing ring, and wrap the cable sheath tightly. sealing effect. For example, Chinese Patent 201280048793.3 discloses a panel cable gland with a frame element composed of at least two frame parts, the frame el...

AI Technical Summary

Problems solved by technology

The fixing of pipe joints in the prior art requires additional sealing treatment, the structure is complex, the effect is not satisfactory, and it is troublesome to use; the way of connecting the threading pipe for sealing also has the above problems; the sealing effect of the flange rubber is good, but it is troublesome to use. The cost of the cabinet will increase by several thousand, which discourages many enterprises
