An ignition distributor having a radio wave noise suppressing function has a rotor electrode and counter electrodes. At least the cathodic one of the rotor electrode and the counter electrodes is provided at its end with a coating layer of a material which is a mixture of a metal oxide having a high electric resistance and a metal oxide which constitutes a dielectric body stable in a high-temperature atmosphere. The metal oxide having high electric resistance consists essentially of 10 to 50 wt % of Cu.sub.2 O and 90 to 50 wt % of CuO, while the metal oxide constituting the dielectric body essentially consists of 70 to 90 wt % of alumina with respect to the weight of the metal oxide having high electric resistance.

Ignition distributor with noise suppression electrode oxide coating

A distributor cap for use in an internal combustion engine includes the ignition cable 5 having at one end thereof a terminal member 9. A bonding member 10 is molded from a hot-melt adhesive resin such as to bury both the terminal member and a portion of the ignition cable in the vicinity of the one end. A connecting member 11 is integrally secured to the bonding member, the connecting member being molded from a resin having the same quality as that of the resin employed to form the distributor cap. The connecting member is adapted to receive a longitudinally intermediate portion of the terminal member such that a distal end portion 9' of the terminal member is exposed to the outside. A tower portion 4 of the distributor cap is formed with a recess 15 which receives the connecting member. Further, the connecting member is fitted into the recess and is integrally welded to the tower portion.

Distributor cap with ignition cable

A terminal of a high tension voltage generated by an ignition device is embedded in a connector structure having a housing which is open at one end thereof to permit the terminal of a conductor to make an electrical connection with the embedded terminal. A sealing member of an elastic material is seated in the space between the conductor and the interior walls of the housing. A cup-shaped cover member is mounted about the conductor to enclose the housing and held in position so that it provides a pressure contact with the sealing member to fluid-tightly seal the terminals from the outside.

Connector for automotive ignition devices

An ignition cable for supplying voltage to the spark plugs of an internal combustion engine, the cable having a low electrostatic capacity such that it does not produce noise in an FM radio frequency band. A central reinforcing string made of aramido-type fibers is covered by a ferrite core. A resistance wire having 8,000-14,000 turns/meter is wound onto the core. The assembly is then coated with a polyolefin insulation layer, a crossed-fiber reinforcement layer, and a silicon sheath, respectively.

Low electrostatic capacity wire-wound type ignition cable

A high voltage ignition cable is described comprising a resistive-conductor core, an insulator layer, and a jacket, wherein the resistive-conductor core comprises a tension member, a semiconductive internal layer, a semiconductive external layer, and a stripping layer interposed between the semiconductive internal layer and the semiconductive external layer.

Ignition cables

A high voltage ignition cable is described comprising a resistive-conductor core, an insulator layer provided thereon, and a jacket, wherein said insulator layer comprises a cross-linked product of a polymer composition consisting of crystalline polyethylene and a non-crystalline olefin polymer.

A high voltage ignition cable having low capacitance comprising a resistive-conductor core, an insulator layer, and a jacket, wherein the resistive-conductor core comprises a tension member prepared by intertwining a plurality of polyaramide fiber bundles around a central polyaramide fiber bundle, is described.

A process for preparing a high voltage-ignition cable having a low electrostatic capacity comprising a resistive-conductor core, an insulator layer and a jacket layer, which comprises preparing a resistive-conductor core comprising a fiber bundle and a semiconductive material provided on at least on the circumferential surface thereof, extrusion coating a polyolefin resin on the circumferential surface of the resistive-conductor core to form an insulator layer, irradiating the insulator layer with electron beam to effect cross-linking of the resin, extrusion coating a polyolefin resin, without providing a reinforcing layer or after providing a reinforcing layer, on the cross-linked insulator to form a jacket and irradiating the jacket with electron beam.

Ignition high voltage cord cover

An improved ignition coil cover is generally shaped like a cup and divided into two parts or first and second cover segments. The segments are assembled and fitted on an ignition coil so that salt water, water or the like is prevented from entering the cover.
