TH80450B - Electromagnetic relay - Google Patents

Abstract

The invention provides an electromagnetic relay that does not require a braided wire to maintain capacity. In the power transmission of the main contact unit The electromagnetic relay consists of a set of 2A primary contacts that are inserted into the transmission path to the load. And a set of 3A arc contacts connected as In parallel with the main contact set 2A, the auxiliary contact 4 separates the electrical part from the set. Primary contact 2A and arc contact 3A set of contacts 2A consists of contacts. The stationary core 27 that is fixed to the frame 1 and the main contact spring 23 comprising the leaf spring and which attaches to the moving main contact 25 that is articulated and separated. From the 27 fixed main contact, the 3A arc contact unit and the auxiliary contact 4 are aligned together. Main contact spring 23 extends in the direction in which the unit is positioned. Arc contact 3A and auxiliary contact set 4, so the main contact spring 23 is made for Extended length is possible in frame 1 and the cross-sectional area can be expanded without increasing the spring constant and no braids required.
