Abstract:
A spark plug connector for connecting to a ceramic shaft spark plug for use in a spark plug well of an engine cylinder in an internal combustion engine, comprising:a plug-in contact for the electrode connection of a spark plug;a single-piece, rigid, supporting connector sleeve surrounding the plug-in contact and made of an insulating material;a connection for an ignition cable;a first elastic means attached to the connector sleeve which seals a gap between the connector sleeve and the spark plug well, with the spark plug connector being guided in the spark plug well by the elastic means,a second elastic means attached to the connector sleeve which seals a gap between the connector sleeve and the ceramic shaft of the spark plug;a ceramic inlet provided in the connector sleeve which encloses the plug-in contact and the ignition cable connection, whereby the plug-in contact and the ignition cable connection are embedded in the ceramic inlet such that the ceramic inlet axially protrudes beyond the plug-in contact and the ignition cable connection,further characterized by:a) the connector sleeve in the area enclosing the ceramic inlet comprises shoulders for providing a positive fit between the ceramic inlet and the sleeve material of the connector sleeve; andb) the material of the connector sleeve has a high melting point and a high electric strength.
