AI Technical Summary

Technical Problem

When assembling the magnetic circuit components of existing contactors, the fixed iron core needs to be riveted and fixed with the yoke core, resulting in complex structure, high processing cost and low assembly efficiency and accuracy.

Method used

The magnetic circuit pressure plate is riveted and fixed, and is pressed between the yoke and the magnetic circuit pressure plate through a coil frame. The upper and lower ends of the fixed iron core are pressed against the limit step instead of the riveting and fixing, simplifying the structure, reducing processing costs, and improving Assembly efficiency and accuracy.

Benefits of technology

The simplification of the fixed iron core structure is achieved, processing costs are reduced, assembly efficiency and accuracy are improved, and stability between various components is enhanced.

Abstract

The utility model discloses a quickly assembled contactor, which comprises a yoke, a magnetic circuit pressing plate, a fixed iron core and a coil rack, the magnetic circuit pressing plate is riveted and fixed with the yoke, the coil rack is tightly pressed between the yoke and the magnetic circuit pressing plate, a coil is wound outside the coil rack, a through hole is arranged in the coil rack, the lower side of the through hole is recessed inwards to form a first annular groove, and the fixed iron core is arranged in the first annular groove. A first annular groove is formed in the yoke, a first limiting step is arranged at the top of the first annular groove, the fixed iron core is of a hollow pipe body structure and installed in the first annular groove, the upper end and the lower end of the fixed iron core abut against the portion between the first limiting step and the yoke respectively, the magnetic circuit pressing plate and the yoke are fixed in a riveted mode, and the coil frame is pressed between the yoke and the magnetic circuit pressing plate. The upper end and the lower end of the fixed iron core abut against the position between the first limiting step and the yoke respectively, the fixed iron core and the yoke do not need to be riveted and fixed, the fixed iron core is simple in structural design, low in machining cost and high in assembly efficiency and precision, and therefore the assembly stability of all parts is improved.
