Abstract
An explosive-containing casing is provided with a cap to which a nipple is secured. The nipple supports a rigid rod which extends the length of the casing and which in turn supports a detonation train for the explosives within the casing. An electrical connector arrangement is joined to the nipple to permit a conductive path to be established to a detonator which forms part of the detonation train. The nipple is secured to the cap in a manner which prevents the entry of water or other undesirable substances into the casing.
