Cable gland and electrical device

Abstract

The invention discloses a cable fixing head, which comprises a cable fixing head and a nut at one end of the cable fixing head, the other end of the nut is screwed to a threaded sleeve body through a first O-shaped waterproof ring, and the other end of the threaded sleeve body is threaded through a second O The threaded connection of the type waterproof ring has a breakout head, and the nut, the first O-type waterproof ring, the main body of the threaded sleeve, the second O-type waterproof ring and the breakout head are connected in sequence from left to right, between the main body of the threaded sleeve and the breakout head The inner cavity is provided with an inner clamp, the inner clamp includes a lower sleeve, and a port of the lower sleeve is connected to the middle sleeve, and the upper end of the clamping claw is provided with a bevel chuck. The beneficial effects achieved by the present invention are: cable fastening Higher resistance, stronger tensile strength; improved waterproof, dustproof, acid and alkali resistance and other performances of the cable fixing head, and improved anti-magnetic and insulation effects at the cable connection; the cable fixing head is connected to the electrical equipment box at one port , It can also be threaded into the electrical equipment of the internal thread of the import and export text.

Description

technical field [0001] The invention relates to a cable fixing head, in particular to a cable fixing head and electrical equipment, and belongs to the technical field of cable fixing tools. Background technique [0002] Cable glands (also known as cable waterproof joints, cable joints) are widely used in the fixing and protection of wires and cables for mechanical equipment electrical, marine electrical, and anti-corrosion equipment. The main function is to keep the cable outlet hole sealed and waterproof and dustproof, so that the machine can run safely and reliably. However, the existing cable fixing head has poor fastening performance. Due to external dragging, it is easy to loosen horizontally, resulting in loosening of the cable joint, which is not conducive to use, and the performance of waterproof, dustproof, acid and alkali resistance is poor, and long-term use causes the cable The later maintenance and replacement of the fixing head is very frequent. Therefore, in ...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a cable fixing head, which is designed by interlocking the clamping claw and the clamping ring in the main body of the threaded sleeve, and the other end is assembled and fastened by the breaking head and the locking piece on the breaking head, the surface of the cable fixing head Both are made of high-quality nickel-plated brass, the waterproof ring and the clamping ring are made of top nitrile rubber, and the cable passes through the inner protection part, which effectively solves the problem of poor cable fastening of the existing cable glands, waterproof and dustproof , acid and alkali resistance, etc. are poor, which is not conducive to long-term use
