Embodiment 1

[0015] Example 1 as figure 1 As shown, this embodiment provides a sealing structure for the cable outlet hole of an electrical device. The cable outlet hole sealing structure includes an insulating gasket 1 with several small holes, a cable lug rubber bollard 2 with several small holes, Several special-shaped metal pressure rings 4 with round holes in the middle, several special-shaped rubber sealing rings 5 ​​with round holes in the middle, several spring washers 6 with round holes in the middle, and hollow compression rings with round holes in the middle Screw plug 7, the above-mentioned components are installed in the outlet hole of electrical device 12 in the following order: firstly, the internal wire 11 of electrical device 12 passes through the small hole in insulating washer 1 through insulating washer 1, and then passes through the hole in the rubber bollard 2 of the cable lug. The small hole passes through the rubber bollard 2 of the cable lug, and then the hollow co...

Embodiment 2

[0016] Example 2 as figure 2 As shown, in order to meet the sealing requirements of the cable hole with shielding layer, the cable outlet hole sealing structure also includes a cable shielding layer metal pressure plate 3 with a round hole in the middle, the insulating gasket 1 and the cable lug rubber cover There are multiple threading holes in the middle of the column 2. The metal pressure plate 3 of the cable shielding layer, the special-shaped metal pressure ring 4, the special-shaped rubber sealing ring 5, the spring washer 6 and the hollow compression plug 7 are all ring-shaped. The order of installing the above components in the outlet hole of the electrical device is as follows: firstly, the internal wire 11 of the electrical device 12 passes through the insulating washer 1 through the small hole in the insulating washer 1, and then passes through the hole in the rubber bollard 2 of the cable lug. The small hole passes through the rubber bollard 2 of the cable lug, an...

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...
