Abstract
A slider (36) has a base fixture (40) and a shielding tube (42). The slider (36) is used to operably couple a detonator (44) to a detonating cord (62) that passes through a booster device (10), i.e., to prevent the detonating cord (62) from directly initiating or fracturing the booster (10). The base fixture (40) includes input lead-retaining means for disposing the input lead (47) of a detonator (44) in signal transfer relation to the detonating cord (62). Optionally, the slider (36) has a detonator retainer (38) for carrying the detonator (44) on the slider (36). Preferably, the detonator retainer (38) is able to hold detonators of various lengths in proper position to initiate the booster device (10). By disposing the shielding tube (42) on the slider (36) a booster device (10) can be used with various detonating cords (62) and a slider (36) having a shielding tube (42) suitable for the chosen detonating cord (62) can be inserted into the booster device (10).
