  • Patent number: 6932627
    Abstract: A connecting means for ignition systems in internal combustion engines is designed such that the connecting means is functionally reliable even under unfavorable operating conditions. The connecting means has, among other things, a first connection for an ignition coil, a second connection for a spark plug, and a covering cap encasing these connections. The covering cap is made of two layers, having an inner casing made of electrically insulating material and an outer casing lying directly on the inner casing, the outer casing being made of an electrically conductive material, which is electrically connected to ground potential. The casings are each made up of a resilient material. The connecting means is for use in the automotive industry.

  • Patent number: 4968858
    Abstract: The distributor has a distributor rotor with a radially extending rotor electrode attached nonrotably to a drive shaft, a distributor cap provided with a number of connectors on top each having a through-going opening in an interior wall of the cap, a center electrode insertable through the center connector in the cap and distributor electrodes insertable through peripherally disposed connectors so that they are positionable spaced from the rotor electrode during rotation of the distributor rotor past them, connecting cables each of which are connected to an electrode for conveying ignition energy to a spark plug and retaining members each releasably holding one of the distributor electrodes in place in the cap. The free end of one of the electrodes may be serrated or knurled while its other end together with the connected end of the connecting cable is enclosed by a lip member made of an elastic insulating material, in which one of the connectors is insertable and tightly held.

  • Patent number: 4351309
    Abstract: To protect the ignition system against high over voltages upon removal of a load in the high voltage circuit, represented by the spark gap of a spark plug, and a distribution gap of a distributor, an electrically conductive terminal element, such as a flag, a spring biased tab, or a push spring which is connectible to ground or chassis is so located that, when the spark plug cable terminals are connected, the insulator of the spark plug cable terminal will be interposed between the flag and the high voltage terminal which is to be protected.
