Electrical detonator plug - has housing contacts pressing against joint with centre pin having split ball head and radial spring loading

摘要

The electrical plug is used for contacting a detonator, where the shape remains constant during the flanging process. It ensures a secure detonator joint after the flanging process. The contacts are contained in a housing which can press against the plug joint. There is a centre pin (34) with spring loading in the radial direction and a prong (13-15) which is spring-loaded in the plug-in direction and extends beyond the housing (1). The centre pin is slit along the axis and has a ball head.
