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 for the retention of shock tubes therein, wherein the slot is configured to induce a bend 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.

La présente invention concerne un bloc de connexion servant à maintenir au moins un tube à choc dans une relation de transmission de signaux avec l'extrémité de percussion-déclenchement d'un détonateur. Le bloc de connexion de l'invention comprend une fente (7, 26, 46, 64, 87) destinée à retenir des tubes à choc dans le bloc, la fente étant configurée pour produire une courbure (8a, 27a, 47a, 91a) dans le(s) tube(s) à choc, ce qui améliore sensiblement la position de ce(s) dernier(s) relativement au détonateur. Les bulles d'air présentes entre le(s) tube(s) à choc et le détonateur et résultant de tolérances de fabrication peuvent être sensiblement éliminées. De plus, les blocs de connexion de l'invention présentent une sécurité accrue en termes de rétention du (des) tube(s) à choc, ce qui réduit le risque de décrochage ou de déplacement accidentel du (des) tube(s) à choc.
