Example Embodiment

[0015] Example 1 figure 1 As shown, this embodiment provides a cable outlet hole sealing structure of an electrical device. The cable outlet hole sealing structure includes an insulating gasket with a plurality of small holes 1, a cable lug rubber bollard with a plurality of small holes 2, Several special-shaped metal pressing rings with a round hole in the middle 4, several special-shaped rubber sealing rings with a round hole in the middle 5, several spring washers with a round hole in the middle 6 and a hollow pressing ring with a round hole in the middle Plug 7, the order in which the above components are installed in the outlet hole of the electrical device 12 is to first pass the inner wire 11 of the electrical device 12 through the small hole in the insulating washer 1 through the insulating washer 1, and then pass through the cable lug rubber bollard 2 The small hole passes through the rubber bollard 2 of the cable terminal, and then the hollow compression plug 7, the sp...

Example Embodiment

[0016] Example 2 such as figure 2 As shown, in order to meet the need of sealing the cable hole with shielding layer, the cable outlet hole sealing structure also includes a cable shielding metal pressing plate 3 with a round hole in the middle, the insulating gasket 1 and the cable lug rubber protection There are multiple threading holes in the middle of the column 2. The cable shielding metal pressing plate 3, the special-shaped metal pressing ring 4, the special-shaped rubber sealing ring 5, the spring gasket 6 and the hollow pressing plug 7 are all ring-shaped. Cables can be used. The sequence of installing the above components in the outlet holes of the electrical device is to first pass the internal wires 11 of the electrical device 12 through the small holes in the insulating washer 1 through the insulating washer 1, and then pass through the cable lug rubber bollard 2 in the The small hole passes through the rubber bollard 2 of the cable lug, and then the hollow compre...

Abstract

The invention provides a sealing structure for a cable outgoing hole of an electric device. The sealing structure comprises an insulating gasket, a cable lug rubber protecting column, special-shaped metal pressing rings, special-shaped rubber sealing rings, spring washers and a hollow pressing screwed plug. According to the sequence that the parts are installed in the cable outgoing hole, firstly, wires in the electric device sequentially penetrate the insulating gasket and the cable lug rubber protecting column; next, the hollow pressing screwed plug, the spring washers, the special-shaped metal pressing rings and the special-shaped rubber sealing rings are arranged on the cable in a sleeving mode one by one; then, core wires of the cable are connected with the wires in the electric device to form a string-shaped connected body; and finally, the string-shaped connected body is pushed into the cable outgoing hole of the electric device, the string-shaped connected body and the cable outgoing hole of the electric device are connected and screwed down through the hollow pressing screwed plug with threads and hole opening threads of the electric device, and therefore all the parts can be compressed, the special-shaped rubber sealing rings can generate elastic squeezing, gaps in the hole are squeezed due to inner retraction and outer expansion, and sealing is achieved. The sealing structure is practical, reliable and excellent in waterproof effect.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a sealing structure for a cable outlet hole of an electrical device. Background technique [0002] For electrical devices installed outdoors, the electrical signals generated by its internal circuits and components must be output through cables with shielding layers, and the cables are drawn out through the outlet holes on the housing of the electrical device. Due to the harsh environmental conditions of the electrical device, the rain and the sun, the cable outlet is easy to enter water and be impregnated by accumulated water, which will damage the internal circuit electrical components, cause the electrical device to lose its function or reduce its use accuracy, and affect its performance. In terms of service life and service life, the existing sealing methods cannot achieve the sealing effect of the sealing structure, and cannot meet the needs of some electrical devices with high sealing...
