Abstract

The present invention provides a low-noise electromagnetic switch applied to an electric car, whereby noise generated by vibration from an inner switch is prevented from being transmitted to the outside box by filling up a filler-up material between the inner switch and the outside box.

Description

technical field [0001] The invention relates to an electromagnetic switch for breaking direct current, in particular to a low-noise electromagnetic switch and a manufacturing method thereof. Background technique [0002] In electric vehicles such as hybrid (HYBRID) vehicles, fuel cell vehicles, golf carts (GOLF CART) and electric forklifts, the electromagnetic switch for breaking the DC current is set between the battery and the DC current conversion device. The function of supplying or cutting off the DC current in the battery to the DC current conversion device. [0003] Moreover, for environmentally friendly power generation systems such as solar power generation systems and wind power generation systems, the electromagnetic switch for breaking the DC current is installed between the DC generator and the inverter that converts the DC generated current into an AC current with a common frequency and voltage. (Inverter) performs the function of supplying or cutting off the ...
