Abstract:
An electrical connection for a spark plug, comprising:a case having a high voltage terminal adapted to be connected to a high voltage source for exciting said spark plug; a connector portion extending from said case, said connector portion defining a cavity sized to receive a head of said spark plug therein; an insulating boot secured to said case and adapted to be connected to said spark plug; and a leaf spring member secured to said high voltage terminal and resiliently acting on an inner peripheral surface of said connector portion, said leaf spring member adapted to bear against said head of said spark plug thereby establishing an electrical connection between said leaf spring member and said head, wherein said high voltage terminal comprises a post member, said leaf spring member being fitted onto said post member to thereby provide a positive connection therebetween, and wherein said leaf spring member comprises: a first end having a central aperture configured to frictionally fit onto said post, said first end being generally disk-shaped; and a plurality of resilient legs extending along a longitudinal direction of said connector, said first end and said legs comprising electrically conductive material.
