Connector for glow plug for diesel engines has housing, power contact and signal contacts both of bushing type and designed as open cylindrical fring ; glow plug to function with such connector

摘要

Connector with pre-warming device and integrated pressure transducer comprises housing (10) made of electrical insulating material, with power contact (20) arranged at the center to be assembled on plug and to be connected to the power contact of the pre-warming device, when the connector is pushed onto glow plug. It has signal contacts (18) which are arranged on the housing and designed to come into contact with the integrated transducer of glow plug, when the connector is pushed onto the glow plug. Both power contact and signal contacts of the " bushing" type are embodied as open cylindrical rings. Ring which forms the connector bushing of the connector is formed from form punching and bending metal sheet elements.
