Abstract
A connector device (10, 214) for transferring a nonelectric blast initiation signal from a donor line (26, 224) to an acceptor line, e.g., an input stub (24, 217) has donor line retaining means (20a, 20b, 229) for disposing a donor line (26, 224) in signal transfer relation to the input stub (24, 217). An anvil member (27, 130, 226) is provided to support input stub (24, 217) at the point where it is in signal transfer relation with the donor line (26), preferably in conforming contact with the donor line (26). In a particular embodiment, the connector device has a body portion (10a) on which is retained a detonator cap (22). Cap (22) detonates upon receipt of a detonation signal from an input stub (24), optionally after a delay period if delay elements are incorporated into the cap 22. The connector device (10) has retainer spring clips (20a, 20b) for retaining the donor line (26) in signal transfer relation to the input stub (24). An output line retaining member (16) holds the output line (28) in signal transfer relation to the detonator cap (22).
