Abstract

A glow plug connector for a glow plug with built-in sensor, especially built-in pressure sensor, comprising a casing made of an electrically insulating material, which can be placed onto the glow plug. Provided centrally in the casing is a high-current connection which is connected to the high-current contact of the heating devices of the glow plug when the connector is placed thereon. Sensor contacts are provided on the casing insulated with respect to the high-current connection for contacting the sensor connections of the built-in sensor when the connector is placed thereon. For sealing an O-ring is provided on the outside of the casing whereas a locking mechanism serves to deliver the withdrawal force which must be overcome so that a coupling placed thereon can be removed from the glow plug connector. The connector is part of a system with a glow plug connector and glow plug.
