Abstract: The present invention relates to an electrical plug connector for a safety restraint system, preferably for an airbag ignition system. The plug connector includes at least two contact terminals assigned to the plug connector and a shorting clip that is configured to short-circuit the at least two contact terminals in an uncoupled or incorrectly coupled condition of the plug connector. The shorting clip includes at least two contact blades. Each contact blade is electrically connected with one of the at least two contact terminals. Each of the contact blades includes at least one cutting edge. The cutting edges contact each other such that one edge cuts the other when the plug connector is in an uncoupled or incorrectly coupled condition.

Abstract: A fluid injector comprising a coil arranged to drive a pump from a first state to a second state when energized, so as to pump a dosing fluid; a PN junction electrically arranged across the coil to discharge energy stored in the coil when the voltage across the coil is above a threshold. In one particular embodiment, the fluid injector is a selective catalytic reduction dosing fluid injector.
