Exciting coil terminal block fixing device of magnetic contactor

摘要

The present invention relates to the excitation coil terminal block fixing device of the magnetic contactor to reduce the failure rate by the wire disconnection, etc. by fixing the terminal block of the excitation coil to the bobbin.;The present invention for this purpose is provided with a bobbin, a bobbin coil wound on the bobbin to generate a magnetic force according to the application of power, and a bobbin coil terminal installed on one side of the bobbin to deliver external power to the coil section. In one magnetic contactor; The bobbin coil terminal block 42 is a flat plate without a separate bent portion, the portion of the bobbin coil terminal block 42 of the bobbin 40 is to be installed, the space portion 40c so that a portion of the bobbin coil terminal block can be inserted. And a plurality of protrusions to press the upper and lower surfaces of the bobbin coil terminal block 42 inserted into the space part and restrain the bobbin coil terminal block from escaping to the outside of the bobbin. 40d) and a protrusion piece 40e protruding upward from a portion where the terminal connecting portion tip of the bobbin coil terminal block is located, so that the bobbin coil terminal block does not flow in the longitudinal direction as well as in the transverse direction from the bobbin. It is to strengthen the bond to avoid.
