A laser spark plug configured to be installed into a plug shaft of an internal combustion engine, and to focus laser ignition energy into the combustion chamber via combustion chamber-side, and thus proximal end, of the laser spark plug has, at a distal end of the laser spark plug opposite to the proximal end, a connecting unit for detachable mechanical and thermal connection to a cooler, the connecting unit being designed to permit the connecting and the disconnecting of the cooler when the laser spark plug is installed in the plug shaft.

An ignition laser, includes a laser-active solid-state body, a housing and a combustion chamber window, the housing having an inner sleeve and an outer sleeve. An insert is provided between the inner sleeve and the outer sleeve, the insert and the combustion chamber window being joined sealingly and integrally.

The apparatus simplifies release of the locking connections. The second housing section of the electrical device is designed rotationally asymmetrically in such a way that when rotated about the longitudinal axis, the electrical device at one particular side wall of the second housing section causes the at least one locking connection to open.

Apparatus for attaching an electrical device to a housing

A device for energy storage and energy transformation is described, in particular an ignition coil of an ignition system of a motor vehicle, having a magnetically active I core, which is surrounded by a first coil former having a winding connected to a supply voltage, and a second coil former having a winding connected to a high-voltage terminal, and having a peripheral core forming a magnetic circuit with the I core and enclosing the system made up of the first and second coil formers. In its circumferential extension, the peripheral core has a recess to accommodate an end area of the I core.

An ignition device for an internal combustion engine occupies a small amount of space and is suited for efficient manufacturing. For this purpose, the ignition device has an ignition coil which is designed as a bar ignition coil having a coil former arranged concentrically to a longitudinal axis of the ignition coil, an insulation carrier being coaxially attached to the coil former. The coil former is provided with a winding set, the winding wire of which is continued to the insulation carrier. At this point, an interference suppression element in the form of an inductor is implemented in a continued winding. The ignition device is preferably utilized in motor vehicles.

An ignition coil for an internal combustion engine has a housing composed of an insulating material and having an insertion opening, at least one ring-shaped core composed of a soft magnetic material and having a portion insertable in the housing, a primary coil body and a secondary coil body, a primary coil and a secondary coil wound on the primary coil body and the secondary coil body and arranged coaxially to one another on the portion of the core, the housing being provided with a high voltage dome extending substantially perpendicularly to a central axis of the coil bodies, a connecting pin insertable along a longitudinal axis of the high voltage dome and connected via a diode with a high voltage winding end of the secondary coil. The connecting pin, the diode and the coil bodies with the coils together form an operationally premounted assembly insertable through the insertion opening in the housing. A spacer connected with one of the coil bodies. The housing completely surrounds the core. The connecting pin and the diode is received in the spacer, the diode is arranged coaxially to the longitudinal axis of the high voltage dome.
