Abstract

An electric solenoid having a bobbin structure on which a coil may be wound by machine and providing a plug-in connector with leaf-like contact terminals to which at least one end of the coil wire may be electrically connected by machine wrapping of the wire end about the terminals. The bobbin has a spool portion and a terminal block portion having a projecting formation to be positioned adjacent to the terminals, so that wire extending from the coil under tension may be wrapped first about the formation and then about the terminal to be wrapped to secure the terminal to the formation prior to subsequent wraps of the wire around the terminal.
