A shock tube surface connector for initiating one or more shock tubes including a housing which forms an elongate cylindrical void, an ignition source extending from a position outside the housing to a position within the elongate cylinder, a static isolation cup disposed within the elongate cylinder adjacent to the ignition source, a sealer element disposed in the housing and on the opposite side of the static isolation cup as the ignition source, a metallic sleeve disposed within the elongate cylinder and parallel thereto, the sleeve encompassing a delay train charge at an end adjacent to the sealer element, an output charge adjacent the delay train charge and an airspace at an end opposite the sealer element. The length of the airspace, the curvature of the output charge, and the interior diameter of the metallic sleeve are selectable to vary the radial output and/or focal point of an explosive force created by ignition of the output charge.

A shock tube surface connector for transferring an ignition signal to one or more shock tubes comprising: (a) a housing forming an elongate cylindrical void containing open first and second ends, (b) initiation means for igniting a charge, the ignition means being at least partly disposed within the elongate cylindrical void, (c) means for isolating static charges disposed within the cylindrical void and adjacent to the ignition means, (d) sealer means disposed in the cylindrical void on a side of the static isolation means opposite the ignition means, the sealer means comprising a combustible charge for transferring an ignition signal from the initiation means to a delay means, (e) delay means for transferring an initiation signal from the sealer means to an output charge, the delay means being within the cylindrical void and adjacent to the sealer element, (f) an output charge positioned within the cylindrical void adjacent to the delay means and opposite the sealer means, the output charge comprising a heat sensitive explosive composition, (g) sleeve means for circumscribing the delay means and the output charge, the sleeve means being disposed within the cylindrical void adjacent to the sealer means, and (h) an airspace disposed within the sleeve means adjacent to the output charge on a side opposite the delay means and near the second end of the housing cylinder such that the sleeve means confines radial expansion of an explosive force created by ignition of the output charge while the explosive force is within the airspace.
