Igniter with a multifunctional plug

Igniter for seismic prospection, for mining applications, or for use in the crude oil or natural gas industry, having a detonator in which an explosive material, an igniting element, and an internal wire for initializing the igniting element are situated, the internal wires leading into a plug situated at one end of the detonator, comprising:

• a multifunctional plug comprising:
• a plug base body and a plug cover which is displaceable in the plug base body, the plug cover being displaceable from a first actuating stage into a second actuating stage;
• a receiving channel situated in and extending into the plug base body for introducing an external wire to a slot-shaped blade contact situated in the plug base body;
• and
• a pressure plunger situated on the plug cover, which in the first actuating stage does not protrude into the receiving channel, but which in the second actuating stage protrudes into the receiving channels and displaces the external wire, introduced at that location, perpendicularly with respect to the receiving channel,
• wherein the blade contacts being connected to the internal wire, and in the second actuating stage the pressure plunger pushing the external wires into the blade contact in such a way that the blade contact strips the insulation from the external wire and establishes an electrical connection of the external wire with the internal wires.
