CONNECTOR BLOCK FOR BLAST INITIATION SYSTEMS

摘要

A connector block (10) includes a clip member (30) which cooperates with the signal transmission end (12a) of body member (12) to define therebetween an arcuate line-retaining slot (32) within which one or more signal transmission lines (40) are received in explosive signal communication with the output end (16a) of a detonator (16). Clip member (30) is of decreasing thickness as sensed moving from the proximal end (30b) thereof towards at least its mid-point and is preferably of undiminished width from the proximal end (30b) thereof to the open end (32b) of the line-retaining slot (32). These features and the configuration of the entryway (34) cooperate to facilitate lateral insertion of signal transmission lines (40) into the line-retaining slot (32) and their retention therein over a broad temperature range of use, and provide excellent shrapnel shielding.
