Definitions
- the invention is based on a rod coil for ignition systems, in particular as an ignition coil in internal combustion engines of motor vehicles according to the preamble of claim 1.
- a rod coil which has a cylindrical housing in the basic form.
- a rod-shaped core of an open magnetic circuit is arranged in a central position in the housing and within a winding set.
- the winding set is surrounded concentrically with the interposition of an insulator by a sleeve-shaped longitudinally slotted return tube, which is arranged on an inside, alternatively on an outside of the housing.
- the function of the return tube is to close the magnetic field of the bar coil.
- the rod coil for ignition systems according to the invention with the characterizing features of claim 1 has the advantage that the aforementioned inadequacy is avoided.
- the rod coil is designed so that a packing is arranged between the return tube and the housing. By means of this packing, the housing fits snugly against the return tube, so that no partial electrical discharges take place during operation of the rod coil and the rod coil is protected from failure due to the deterioration of its insulation.
- the single figure shows the rod coil in a longitudinal section, in which a filler body between a return tube and a housing of the rod coil is shown oversized for better visibility.
- a rod coil 11 for ignition systems according to the figure, in particular as an ignition coil in internal combustion engines of motor vehicles, is provided for direct contacting with a spark plug, which is inserted in a shaft in the cylinder head of an internal combustion engine in the usual and not shown manner.
- the rod coil 11 contains an elongated, cylindrical core 14, which is also referred to as an I-core.
- the core 14 consists of layered magnetizable material and is part of an open magnetic circuit.
- a low-voltage primary winding 16 and a high-voltage secondary winding 17 are arranged concentrically around the core 14 on the inside.
- the windings 16, 17 are surrounded by a return tube 18 made of a magnetizable material for guiding the magnetic field of the rod coil 11, which is mounted on an inside 19 of the housing 13.
- a return tube 18 made of a magnetizable material for guiding the magnetic field of the rod coil 11, which is mounted on an inside 19 of the housing 13.
- Yoke tube 18 can also be attached to an outer side 21 of the housing 13.
- the yoke tube 18 is slotted parallel to the longitudinal axis 12 to prevent a short circuit of the magnetic field.
- a filler 22 is arranged between the return tube 18 and the housing 13, in the exemplary embodiment shown here between the return tube 18 and the inside 19 of the housing 13.
- This filler 22 can be designed as a hot melt adhesive and for example made of
- Polyolefin, polyamide or made of a silicone-based fabric are examples of polyolefin, polyamide or made of a silicone-based fabric.
- the filler 22 can consist of an epoxy resin coating, which can be both electrically conductive and electrically insulating and is attached to the housing 13 or the return tube 18.
- the filler body 22 could surround the housing 13 with a return tube 18 on the outside 21 of the Housing 13 are applied, but especially when the filler 22 consists of a shrink tube.
- the packing 22 can produce an intimate, gapless bond between the return tube 18 and the housing 13.
- electrical partial discharges are avoided when the rod coil 11 is operated on it. This prevents failure of the rod coil 11 due to the deterioration of its insulation.
