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.

Abstract: A plug-in connector for a diesel-engine glow plug has a housing centered on an axis and fittable with the glow plug and a plurality of contacts in the housing. A first latch on the housing is displaceable when the housing is fitted to the glow plug between an unlocked position permitting the housing to be installed on and removed from the glow plug and a locked position for fixing the housing to the glow plug. A second latch on the housing is displaceable between an unlocked position permitting the first latch to move between its locked and unlocked positions and a locked positions holding the first latch in its locked position.
