Cable watertight stuffing box and using method thereof

Abstract

The invention discloses a cable watertight stuffing box and a using method thereof. The cable watertight stuffing box comprises a box base and a box body fixedly connected onto the box base, wherein through cable holes are arranged in the box base and the box body, and a plurality of stuffing cavities are arranged in the cable holes. The using method includes: A, enabling cables to penetrate through the box body and the cable holes in the box base; B, rotating a fastening nut and compressing a sealing pad and a plane sealing ring on the lower side of the fastening nut; C, removing an outer layer protective sleeve in a second stuffing cavity, and filling sealing agents into the second stuffing cavity after a cable core is exposed; D, cutting the cable cores according to the wiring length and removing surface layer protective sleeves of wiring ends of the cable cores, and installing wire lugs after the metal cable cores are exposed; and E, dripping fast-dry glue on the connection portion of the metal cable cores and the surface layer protective sleeves and the surfaces of the wire lugs and the metal cable cores, and removing the fast-dry glue on the conducting position of the wire lugs after the fast-dry glue is cured. The multilayer sealing protection of the cables is finished by the plurality of stuff boxes, and the watertightness of the cable watertight stuffing box is effectively improved. The cable watertight stuffing box and the using method are used in the field of cable connection and sealing.

Description

technical field [0001] The invention is used in the field of connection and sealing of electric cables, and in particular relates to a watertight stuffing box and a using method thereof. Background technique [0002] The watertight stuffing box is mostly assembled on the junction box or the sensor, as a structure for the junction box or the internal cable of the sensor to output to the outside. Among them, the junction box is a type of industrial connector. The junction box is a device that can output multiple current or data signals after a power supply or data is shunted and converted. [0003] In order to ensure the normal operation of the electrical components inside the junction box or sensor, the junction box or sensor is required to have good watertightness. If the watertight performance of the junction box or sensor is unstable, moisture will penetrate. In particular, once the cable in the watertight stuffing box is damaged, the water will spread to the sensor, the ...

AI Technical Summary

Problems solved by technology

Especially once the cable in the watertight stuffing box is damaged, the water will spread to the sensor, the junction box, etc. along the cable core bundle under pressure, and electrolytic corrosion will occur between the cable core and the water, thereby damaging the sensor connector. This directly affects the normal operation of the equipment
