Description

TECHNICAL FIELD

[0001] The utility model belongs to the electrical field, concretely relates to a novel shockproof device of small current electromagnetic contactor. BACKGROUND

[0002] At present, small current electromagnetic contactors (rated working current is not more than 38A) are indispensable in the low-voltage electrical industry in the domestic and foreign electrical field, but they cannot work normally in some special electrical environment with strong impact vibration or in some intermittent strong impact vibration environment with high motion state frequency. In addition, in some fields prone to sudden strong impact vibration (such as earthquake, hurricane, sudden strong explosion, etc.), small current electromagnetic contactors also face the risk of unhooking, breaking and cracking, and cannot work normally.

[0003] Generally, in the electrical environment with strong impact vibration, small current electromagnetic contactors are basically replaced by large current electromagnetic contactors, and the large current electromagnetic contactors are basically fixed and connected with each other by metal parts as the base. At the same time, the large current electromagnetic contactors are usually very large in size, require a large space for installation, and consume a large amount of power. Although the large current electromagnetic contactors can replace the small current electromagnetic contactors, the economic cost and resource consumption are not worth the price. Moreover, the large current electromagnetic contactors are fixed and installed with each other by metal parts as the base, and there are certain safety hazards in leakage performance and dielectric performance in the contactor industry test index after being subjected to external strong impact vibration.
