Abstract
The present invention discloses an electromagnetic coil means, comprising a terminal part and pins passing through the terminal part, wherein the pins are divided into a first group of pins connected with an upper coil stator and a second group of pins connected with a lower coil stator which are spaced apart from each other; the first group of pins comprises first outer sections with first head portions and first inner sections with first root portions; the second group of pins comprising second outer sections with second head portion and second inner sections with second root portions; the first and second head portions extend out from a pin leading-out surface of the terminal part, characterized in that, at least one group of the first and second groups of pins are bent, and a distance between adjacent said first and second head portions is larger than that between adjacent said first and second root portions. By this electromagnetic coil means, the distance of solder joints between adjacent head portions of pins is increased, thus the insulation performance between the solder joints is improved.
