Internal combustion engine ignition coil apparatus
An internal combustion engine ignition coil apparatus includes: a case; a center core disposed in the case; a primary coil and a secondary coil disposed outside the center core inside the case; a high-voltage cord having: a first end portion electrically connected to the secondary coil; and a second end portion electrically connected to a spark plug; and a protective tube covering an outer peripheral surface of the high-voltage cord, a rim portion projecting away from a high-voltage terminal being formed so as to surround an insertion aperture in a bottom portion of the case, and a leading end portion of the protective tube covering and elastically engaging with the rim portion, wherein: a receiving portion having a radially-outwardly-projecting V-shaped cross-sectional shape when sectioned axially is formed on an end portion of the rim portion.
1. An internal combustion engine ignition coil apparatus comprising:
a cup-shaped case;
a center core disposed in said case;
a primary coil and a secondary coil disposed outside said center core inside said case;
a high-voltage cord having:
a first end portion electrically connected to said secondary coil by means of a high voltage terminal; and
a second end portion electrically connected to a spark plug; and
a protective tube covering an outer peripheral surface of said high-voltage cord,
an insertion aperture into which said high-voltage cord is inserted being formed in a bottom portion of said case,
a rim portion projecting externally being formed so as to surround said insertion aperture, and
a leading end portion of said protective tube covering and elastically engaging with said rim portion,
wherein:
a receiving portion having a radially-outwardly-projecting V-shaped cross-sectional shape when sectioned axially is formed on an end portion of said rim portion.
2. The internal combustion engine ignition coil apparatus according to claim 1 , wherein:
a stepped portion contacted by a leading end surface of said protective tube is formed on said receiving portion near said high-voltage terminal.
3. The internal combustion engine ignition coil apparatus according to claim 1 , wherein:
an adhesive is interposed between an inside diameter surface of said rim portion and an outer peripheral surface of said high-voltage cord.
