Electrically activated detonator with pyrotechnic device receiving terminals and method of making

摘要

A first terminal extends from the central region of a circular cylindrical contact body. A thermoplastic tube is heat shrunk over the cylindrical surface of the body with a leader protruding from an end of the body. The assembly is press fitted into the bore of a circular cylindrical metal sleeve. The interference fit between the parts causes the plastic tube to stretch and compress holding the parts in clamped relation. The leader prevents the plastic tube from slipping out of the joint during the sliding assembly action. A second terminal extends from the sleeve which is in ohmic contact with a metal casing of a pyrotechnic device. An electrically activated match has its electrodes welded to and between the terminals.
