Abstract

The invention provides a coil unit of electromagnetic contactor and assembling method thereof. In a coil unit of an electromagnetic contactor in which a coil having a coil strand as a conductor wire wound around a flanged bobbin is mounted on a leg of a stationary core of an operating electromagnet, into one flange of the bobbin are press fitted a pair of terminal metal pieces respectively corresponding to an initial side lead wire as an initial side conductor wire and a final side lead wire as a final side conductor wire of the coil, and each of the terminal metal pieces is formed with a press fitting base for making the terminal metal piece press fitted into the one flange, a coil connecting arm around which the lead wire as the conductor wire of corresponding side of the coil is wound and a tab terminal made to have a plug-in connection with a corresponding connector of an extension lead. The initial side conductor wire is wound on a coil connection arm 19b of a terminal metal piece19 and the coil strand is wound on the coil on the bobbin to form the coil. The final side connector wire is wound on the coil connection arm 19b of another terminal metal piece 19. Subsequently thelead wound on each coil connection arm is welded. In addition, the tab terminal is in plug-in connection with connector of the extension lead for external connection and serial connection, therefore the coil unit is assembled into double-coil unit.

Description

technical field [0001] The present invention relates to a coil unit of a working electromagnet mounted on an electromagnetic contactor, and in detail, to a terminal structure of a coil in which coil strands are wound on a bobbin, and to an assembly method of the coil unit using the terminal structure. Background technique [0002] For the coil unit of the working electromagnet that opens and closes the main circuit contacts of the electromagnetic contactor, a single coil unit is generally known in which the assembly with the coil of the coil strand wound on the bobbin is mounted on an E-shaped fixed core on the central stem. In addition, a double-coil unit (DC excitation system) is known, wherein the coil unit is divided into two groups of single-coil units mounted on the left and right legs of the U-shaped fixed magnetic core, respectively, and the coils of each coil unit are connected in series so that Connect with the working circuit (see "the structure of the electromag...
