Abstract
An ignition coil cassette having bushings retained by an irregularity of the bushings being encased by epoxy. As a result, the process by which the bushings are installed into the ignition coil cassette avoids the cost associated with the overmolding installation process, and further avoids the potential for damage associated with the ultrasonic insertion process. The irregularity is located generally adjacent one end of each of the bushings and may be, for example, in the form of an undercut or a protrusion.
Claims10
An ignition coil cassette, comprising:
- a casing having a bushing seat;
- a bushing snuggly received into said bushing seat, wherein said bushing has an irregularity substantially adjacent one end thereof, said irregularity being exposed with respect to said bushing seat, said bushing having a bushing length;
- and
- an epoxy potted into a selected portion of said casing, said epoxy interfacing with said irregularity such as to anchor said bushing with respect to said casing.
A method for providing an ignition coil cassette, comprising the steps of:
- forming a plastic casing having at least one bushing seat formed therein;
- forming at least one bushing having an irregularity adjacent one end thereof;
- pressing said a said bushing into a respective said bushing seat, wherein said irregularity is exposed with respect to said bushing seat;
- placing a liquid state epoxy into a selected portion of said casing, wherein the epoxy interfaces with said irregularity;
- and
- solidifying the epoxy to thereby adhere the epoxy to the casing and interferingly interface the epoxy with respect to the irregularity, whereupon the bushing is anchored by the epoxy to the casing.
