Abstract
A guide hole 16b is formed in the insulation cap 16 of a starter motor electromagnetic switch, and a coil terminal 30 inserted through the guide hole has one or more projections 30b formed at a location corresponding to the guide hole so that the projections are wedged against an inner surface of the hole, thus preventing any resonant vibrations of the terminal and the attendant severing of its attached lead wire 1a.
Claims7
A starter motor electromagnetic switch, comprising:
- a) an excitation coil (1) wound around a bobbin (2), and having a lead wire (1a) extending axially outwardly from one end thereof,
- b) a yoke (4) surrounding the coil,
- c) an insulation cap (16) fixed to one end of the yoke, defining an outwardly extending sleeve member (16a) adapted to receive an inserted coupler (22), and having a guide hole (16b) formed therein,
- d) an elongate coil terminal (30) having an inner end attached to the lead wire, and a mid-portion extending through the guide hole such that an outer end is disposed within the sleeve for engagement by the coupler, and
- e) means for preventing resonant vibrations of the coil terminal and attendant severing or detachment of the lead wire, said preventing means comprising projection means (30b;
- 30c) upstanding from said mid-portion of the coil terminal a sufficient distance to engage an inner surface of the guide hole and to firmly wedge said coil terminal therein.
