つた。(Prior art and its problems) Conventionally, in order to control an AC motor using an inverter, a magnetic contactor, a reactor, a control transformer, a diode module constituting a diode bridge, a smoothing capacitor, a discharge transistor, and a transistor are required to control an AC motor using an inverter. A control panel is provided that is made up of various parts such as transistor modules that make up the inverter. The control panels are increasingly required to be simple and compact, and there is a tendency to automate the assembly of various parts, especially the electrical connections of the various parts. However, the dimensions of the various parts incorporated into the control panel vary, and the positions of the terminals on the parts are not standardized.
The reality is that electrical connections between various components have to be made one by one using, for example, lead wires. In particular, in electromagnetic contactors that control large currents, it is necessary to prevent edge discharge between the power supply terminals of the excitation coil provided on the top surface of the contactor, so a protrusion is provided on the top surface of the casing to increase the distance between the edge surfaces between the terminals. Since the wiring is made large, wiring using a short bar or the like in which a conductive path is formed on an insulating substrate is obstructed. For this reason, there were problems in that wiring work required a long time and was troublesome, and the reliability of the connection was low.

接触器を提供することができる。(Effects of the invention) According to the invention, the power supply terminal to the excitation coil and the external terminals on the input side and output side are led out to the top surface of the casing, and connected to the printed board placed on the top surface of the casing. In the electromagnetic contactor, the top surface of the casing is formed into a flat surface, and the surfaces of the top surface that connect to the printed board of the respective terminals are formed in the same plane, and the excitation coil has a flat surface. Since a spark killer connected to each terminal is built into the housing, each terminal surface can be placed at the same height as other electronic components without the need for protrusions on the top surface of the housing. Wiring can be done using short bars formed on an insulating substrate under the board. In addition, when this electromagnetic contactor is incorporated into a control panel of an electric motor, etc., the top surface can be made compact to reduce space, and since it is incorporated as an electrical component without external connection terminals, it can be installed in the control panel. Automatic assembly becomes easier. Furthermore, the built-in spark killer eliminates the need to connect electrical components to the outside of the electromagnetic contactor, making it possible to provide a compact and highly reliable electromagnetic contactor.
