Description

Technical Field

[0001] The present application relates to the field of anti-electrical sway devices, and in particular to an anti-electrical sway device suitable for electronic coil contactors. Background Art

[0002] An anti-sway contactor is a device used to prevent voltage drops, surges, short-term power outages, and voltage flickers caused by electric sway. For example, an anti-sway device with Chinese patent application number CN202322645623.1 includes an anti-sway contactor, two snap-fit ​​fixing components, multiple guide components, multiple limit components, multiple heat dissipation components, multiple lower conductive plates, and multiple upper conductive plates. Multiple wiring slots are provided on both sides of the anti-sway contactor. Multiple lower conductive plates are respectively fixedly mounted on the bottom inner wall of the corresponding wiring slots. Multiple upper conductive plates are respectively arranged above the corresponding lower conductive plates. Multiple springs are fixedly mounted between the top side of the upper conductive plate and the top inner wall of the wiring slot. Multiple heat dissipation components are respectively arranged on the corresponding upper conductive plates. The utility model has a reasonable design and is simple and convenient to operate. It greatly improves the efficiency of disassembly and wiring of the anti-sway contactor, and also facilitates subsequent maintenance. It can avoid heat accumulation in the wiring slot while ensuring the stability of the connection between the wires and the upper and lower conductive plates.

[0003] However, the above solution still has certain defects: first, the heat dissipation component adopts a natural heat dissipation structure, which results in a long heat dissipation time and poor heat dissipation effect; second, the conductive plate only uses the elastic force of the spring to press and fix the wire, and the fixing effect is poor. The long-term use of the spring will cause the pressing force to become smaller and smaller, causing the wire to fall off easily, thereby reducing practicality. Utility Model Content
