The present invention provides for a connector block for retaining at least one shock tube in signal transmission relationship with the percussion-actuation end of a detonator. The connector blocks of the present invention comprise a slot (7, 26, 46, 64, 87) for the retention of shock tubes therein, wherein the slot is configured to induce a bend (8a, 27a, 47a, 91a) in the shock tube(s). In this way, the position of the shock tube(s) relative to the detonator is significantly improved. Air gaps between the shock tubes and the detonator, resulting from manufacturing tolerances, can be substantially eliminated. Moreover, the connector blocks of the present invention provide an increased security of shock tube retention, thereby reducing the risk of accidental shock tube removal or displacement.

The invention claimed is: 1. A connector block for retaining at least one shock tube in signal transfer relationship with a detonator having a percussion-actuation end, the connector block comprising: a housing with a bore extending longitudinally through the housing for receiving the detonator, and a shock tube retention means cooperating with an end of the housing proximal to the shock tube retention means to form, between the proximal end of the housing and the shock tube retention means, a slot extending transversely with respect to the longitudinally extending bore in the housing, the bore having an end proximal to the slot from which the percussion-actuation end of the detonator protrudes into the slot, when the detonator is positioned within the connector block, the shock tube retention means being wider than the housing at the end of the housing proximal to the shock tube retention means and including first and second protrusions that are proximal to first and second open ends, respectively, of the slot, the first and second protrusions causing the slot to be narrower at its first and second open ends than at a portion of the slot intermediate the first and second protrusions, the first and second protrusions overhanging the housing at the first and second open ends of the slot, wherein the first and second protrusions engage the at least one shock tube, when the at least one shock tube is extending through the slot and the first and second open ends of the slot, so as to cause the at least one shock tube to bend, without kinking, in a curvilinear and concave manner towards, and transverse to, the detonator, to thereby contact the percussion-actuation end of the detonator and be in signal transfer relationship with the detonator, when the detonator is positioned within the bore. 2. The connector block of claim 1, further comprising a positioning membrane for positioning the percussion-actuation end of said detonator in said housing, said at least one shock tube contacting said positioning membrane when in said slot. 3. The connector block of claim 1, wherein the opposing portions of the housing extend outwardly relative to the sides of the shock tube retention means so that the at least one shock tube retained in the slot is caused to bend away from a percussion-actuation end of a detonator retained in the bore. 4. A detonator assembly comprising a connector block of claim 1, a detonator positioned within the bore of the housing of the connector block, and at least one shock tube retained by and extending through the slot of the connector block. 5. The connector block of claim 1, wherein the first and second protrusions engage the at least one shock tube when it is extending through the slot so that a zenith of the curvilinearly bent at least one shock tube is located between the intermediate portion of the shock tube retention means and the proximal end of the housing. 6. The connector block of claim 5, wherein the at least one shock tube is bent towards the detonator so as to have a concave shape with respect to the detonator. 7. The connector block of claim 1, wherein the shock tube retention means is comprised of a flexible, resilient material. 8. The connector block of claim 1, wherein the shock tube retention means is comprised of a rigid material. 9. The connector block of claim 1, wherein the shock tube retention means is sufficiently rigid to bend the at least one shock tube without itself deforming. 10. The connector block of claim 1, wherein the shock tube retention means and the proximal end of the housing are parallel to one another at the intermediate portion of the shock tube retention means between the two protrusions into the slot. 11. The connector block of claim 1, wherein the shock tube retention means' two protrusions into the slot are each inclined towards the proximal end of the housing. 12. A connector block for retaining at least one shock tube in signal transfer relationship with a detonator having a percussion-actuation end, the connector block comprising: a housing with a bore extending longitudinally through the housing for receiving the detonator; and a shock tube retention means cooperating with an end of the housing proximal to the shock tube retention means to form, between the proximal end of the housing and the shock tube retention means, a slot extending transversely with respect to the longitudinally extending bore in the housing, the bore having an end proximal to the slot from which the percussion-actuation end of the detonator protrudes into the slot, when the detonator is positioned within the bore, the shock tube retention means being wider than the housing at the end of the housing proximal to the shock tube retention means and including at least one protrusion into the slot that is proximal to a first or second open end of the slot, the at least one protrusion causing the slot to be narrower at the first or second open end corresponding to the protrusion than at a portion of the slot located other than where the at least one protrusion is located, the at least one protrusion overhanging the housing at the first or second open ends of the slot, wherein the at least one protrusion engages the at least one shock tube, when the at least one shock tube is extending through the slot and the first and second open ends of the slot, so as to cause the at least one shock tube to bend, without kinking, in a curvilinear and concave manner towards, and transverse to, the detonator, to thereby contact the percussion-actuation end of the detonator and be in signal transfer relationship with the detonator, when the detonator is positioned within the bore. 13. The connector block of claim 12, wherein the protrusion into the slot of the shock tube retention mean is inclined towards the proximal end of the housing.
