Definitions
- the invention is based on a rod coil for ignition systems, especially as an ignition coil in internal combustion engines from Motor vehicles according to the preamble of claim 1.
- a rod coil is known from DE 41 32 851 A1 has a cylindrical housing in the basic form. To the A primary connection with contact elements is attached to the housing, the electrical with winding ends one in the housing arranged coil set of the ignition coil are connected.
- a rod-shaped core of an open Magnetic circuit arranged in the housing and inside the coil set.
- the coil set from a longitudinally slotted return plate surrounded concentrically.
- the return plate is from the spark plug shaft through the Ignition coil housing insulated.
- the interference energy depends on the electric field strength between the back plate and Spark plug shaft from. Due to the installation location in Spark plug well, the interference energy is higher than at conventional ignition coils with one over the core material closed magnetic circuit.
- the rod coil for ignition systems with the characteristic features of claim 1 has the opposite the advantage that the aforementioned inadequacy is avoided.
- the rod coil is designed so that the return plate is connected to ground potential and the occurring here, contributing to a partial discharge Charge carriers can be derived against mass. This will the risk of malfunctions in electrical units of the motor vehicle reduced.
- a rod coil 11 for ignition systems according to Figures 1, 2, especially as an ignition coil in internal combustion engines from Motor vehicles, is for direct contact with a Spark plug provided in the usual and no more shown way in a shaft in the cylinder head Internal combustion engine is used.
- the rod coil 11 contains a coaxial arrangement Longitudinal axis 12 in a plastic housing 13 elongated, cylindrical core 14, also called an I-core referred to as.
- the core 14 consists of layered magnetic material and is part of an open Magnetic circuit. Concentric around the core 14 is inside a low voltage primary winding 16 and external a secondary winding 17 carrying high voltage arranged.
- the windings 16, 17 are for guiding the Magnetic field surrounded by a yoke plate 15, the is mounted on the inside of the housing 13.
- the back plate 15 is slotted parallel to the longitudinal axis 12 by one To prevent short circuit of the magnetic field.
- the primary connection 18 has in addition another a first contact element 19, which is electrically on Ground potential is.
- This first contact element 19 is Part of a busbar 21 designed as a sheet metal strip, which in the first embodiment of Figure 1 with a free end 22 with a resistance element 23 electrically connected is.
- the resistance element 23 is again electrically connected to the return plate 15.
- the resistance element 23 or the sheet metal strip 24 cause an equalization of the charge carriers, so that none Interference energy due to a high-energy partial discharge occurs.
