A method and apparatus for transferring non-electric blasting initiation signals from detonating cord signal donor lines to signal transmission tube acceptor lines involves disposing the acceptor line in enhanced signal transfer configuration with the donor line. The acceptor line (30) may constitute the input lead (29a) of a detonator (10a). Enhanced signal transfer configuration between the input lead (29a) and the detonating cord (60) can be established by disposing input line (30) in at least partial wrap-around contact with the detonating cord (60) or in multiple abutting contact with the detonating cord (60). Enhanced signal transfer configuration can also be achieved for a detonator having at least two input lines in abutting contact with the detonating cord. A slider (44) is designed to extend contact between a detonator input lead and a detonating cord. The slider (44) provides a detonator retainer (48) for holding a detonator (10a) and a base fixture (74') that includes a pass-through aperture (58a) for a detonating cord (62). Input lead-retaining means (52) on the base fixture (74') disposes the input lead (29a) in position for enhanced signal transfer configuration with a detonating cord that may extend through the pass-through aperture (58a).
A slider device for positioning in a booster a detonator having an input lead and for disposing the detonator in signal transfer relation with a downline detonating cord, the slider device comprising:
A slider device for positioning in a booster a detonator having an input lead and for disposing the detonator in signal transfer relation with a downline detonating cord, the slider device comprising:
A method for disposing a detonator having an input lead comprising at least two input lines in signal transfer relation to a detonating cord, the method comprising disposing each of the at least two input lines in abutting contact with the detonating cord, wherein the input lead comprises an eyelet lead.
A method for configuring the input lead of a detonator in signal transfer relation to a detonating cord for transferring an initiation signal to the detonator, the detonator being retained within a slider unit comprising a base fixture having a pass-through aperture for receiving a detonating cord therein, the method comprising engaging the input lead on the base fixture in position to provide at least partial wrap-around contact between the input lead and such detonating cord.
A method for configuring the input lead of a detonator in signal transfer relation to a detonating cord for transferring an initiation signal to the detonator, the detonator being retained within a slider unit comprising a base fixture having a pass-through aperture for receiving a detonating cord therein, the method comprising engaging the input lead on the base fixture in position to provide at least two points of abutting contact between the input lead and such detonating cord.
A method for configuring the input lead of a detonator in signal transfer relation to a detonating cord for transferring an initiation signal to the detonator, the detonator being retained within a slider unit comprising a base fixture having a pass-through aperture for receiving a detonating cord therein, wherein the base fixture comprises a base plate, a cover and hinge means for hingedly joining the cover to the base plate, the cover being movable between an open position and a closed position relative to the base plate, wherein the input lead-retaining means comprises a first component on the base plate and a second component on the cover, the base plate and the cover each defining respective apertures that cooperate when the cover is in the closed position to define a pass-through aperture for the base fixture;
