An ignition distributor where the rotor of the distributor is driven by the camshaft of an internal combustion engine. The end of the camshaft has an axially extending bore. The ignition distributor has a coupling. The coupling has an axially extending shaft portion that is located in the bore of the camshaft. The coupling has a laterally extending portion that has a radially extending slot. The camshaft carries a drive pin. One end of the drive pin is located in the slot with the pin engaging internal side wall surfaces of the slot. The pin forms a drive means for driving the coupling from the camshaft. The coupling drives the rotor of the distributor.

Ignition distributor drive

An ignition distributor rotor that is formed of electrical insulating material. The rotor has a retainer portion that is adapted to be pressed onto the end of a distributor drive shaft. This retainer portion has an axially extending wall that has an undulated shape defined by circumferentially spaced undulated portions. The inner surfaces between the undulated portions tightly engage outer surface portions of the shaft. One of the undulated portions is located in a slot in the shaft to form a driving connection between the shaft and the rotor. The retainer portion has a plurality of flexible circumferentially spaced latch arms. The ends of the latch arms are shaped to enter an annular groove on the distributor shaft to thereby lock the rotor from a axial movement relative to the distributor shaft.

Rotor for an ignition distributor

A distributor cap for an ignition distributor. The cap is formed of electrical insulating material. A plurality of electrical connector and terminal assemblies are molded into the cap. Each assembly is comprised of a length of plastic moldable material that supports a metallic insert and a metallic terminal. The ends of the length of plastic material are molded respectively to the insert and the terminal. The length of plastic material is plated or coated with a metallic material such as aluminum and this material also coats portions of the terminal and insert. The metallic coating on the length of plastic material electrically connects the terminal to the insert.

Distributor cap

A distributor cap for an internal combustion engine ignition distributor. The distributor cap is comprised of a cap member formed of insulating material that has terminals located at the outer periphery of the cap member that are adapted to be connected to ignition cables. The cap member has a laterally extending wall. A plurality of electrodes are carried by the wall and extend through the wall. End portions of the electrodes are located inside the wall and are adapted to cooperate with a distributor rotor. A respective terminal is electrically connected to a respective electrode by a conductive ink trace that is bonded to an outer surface of the wall.
