Embodiment 1

[0014] The main structure of a cable sealing joint of a panel cabinet involved in this embodiment is as follows: figure 1 As shown, it includes an inner sealing ring 1, a threaded pipe 2, an outer sealing ring 3, an interface 4 and a through hole 5; the inner sealing ring 1 is connected with the outer sealing ring 3 through the threaded pipe 2, and the center of the inner sealing ring 1 is provided with an interface 4 , the center of the outer sealing ring 3 is provided with a through hole 5 .

[0015] When the cable sealing joint of the panel cabinet involved in this embodiment is used, the outer sealing ring 3 is pressed into the installation hole of the panel cabinet or the distribution box. After the sealing ring 3 is passed through the through hole 5, it enters the panel cabinet or distribution box. The interface and through hole are based on the self-shrinking properties of the TPU (thermoplastic polyurethane elastomer) material, and are tightly attached to the cable. T...

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...
