PURPOSE:To enhance the strength of the connection part of a wire and a wire pin part, a wire speed and durability, by integrally molding the wire pin part and the wire, and setting the wt. of the wire pin part to the specific percentage by wt. of the wire and forming the wire pin part into an almost plate shape. CONSTITUTION:A frame 1 and a core 1a are integrally formed and a coil 2 is engaged with the core 1a. A coil press plate 8 is mounted on the frame 1 and an armature 3 having a plunger 4 connected thereto is pressed to the coil press plate 8 through the fulcrum thereof by a fulcrum press spring 7. A wire pin part 5a integrally molded along with a wire 5 is contacted with the leading end part of the armature 3 by the return spring 9 existing between a nose 10 and the wire pin part 5a. The wire 5 is guided by the nose 10 and wire guides 6a, 6b. When the diameter of the wire 5 is set to (d) and the thickness of the wire in part 5a is set to (t) by header processing, the relation of d>t is formed. The wt. of the wire pin part 5a is 10% or less by wt. of the whole of the wire and the wt. of the wire is reduced by 30% as compared with a conventional one. |
