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.

In a connector block for retaining one or more signal transmission lines in signal transfer relationship with a detonator, the connector block comprising: a body member having a signal transmission end and a detonator channel having a longitudinal axis and terminating in a discharge end, the channel

In a connector block for retaining one or more signal transmission lines in signal transfer relationship with a detonator, the connector block comprising: a body member having a signal transmission end and a detonator channel having a longitudinal axis and terminating in a discharge end, the channel extending within the body member for receiving and retaining therein a detonator having an output end, with the output end disposed at the discharge end of the channel when the detonator is seated therein, the projection of the periphery of the output end of such seated detonator on a plane passed through the discharge end of the channel perpendicularly to the longitudinal axis thereof serving as the origin of a hypothetical blast cone emanating from the discharge end of the channel and having a given apex angle; a line-retaining, curved clip member disposed at the signal transmission end of the body member and cooperating therewith to define therebetween a line-retaining slot extending transversely of the longitudinal axis of the channel for receiving and retaining therein at least one signal transmission line in signal communication relationship with such output end of a detonator retained within the receiving channel, the clip member having a proximal end carried on the body member and an opposite, distal end and the line-retaining slot having a closed end adjacent the proximal end of the clip member and an open end adjacent the distal end of the clip member; an entryway formed between the distal end of the clip member and the body member, the entryway being dimensioned and configured to admit sideways insertion of such transmission line therethrough and into the line-retaining slot by displacement of the clip member, thereby imposing a reaction load on the clip member: the improvement comprising that the clip member is dimensioned and configured to be of continuously decreasing thickness as sensed moving longitudinally along the clip member from the proximal end thereof to at least about the first-encountered intersection of the clip member with a blast cone having a ninety degree apex angle.
