Patent

CA 2233088

A connector block (10) for connecting signal transmission lines in a blast initiation system includes a body member (12) having a channel (18) formed therein for receiving and retaining a detonator (20). A locking member (28) is mounted on the body member (12) in a first position aligned with, but displaced from, its locking position. The detonator (20) is inserted into the channel (18) of the connector block (10) and, if axially misaligned, is properly seated therein by moving the locking member (28) through a passageway (36) to both axially shift the detonator (20) to its seated position and engage to the locking member (28) and the detonator with each other to secure both within the channel (18). A method of assembling a detonator (20) within the connector block (10) to provide a combination of detonator (20) and connector block (10) is also provided.

L'invention porte sur un bloc de connexion (10) destiné à relier une ligne de transmission de signaux à un système de détonation et comportant un corps (12) percé d'un canal (18) destiné à loger un détonateur (20) et un élément de verrouillage (28) monté sur le corps (12) dans une première position, alignée avec sa position de verrouillage, mais déplacé par rapport à celle-ci. Le détonateur (20) ayant été inséré dans le canal (18) du bloc de connexion (10), même non aligné axialement, se met correctement en place lors qu'on meut l'élément de verrouillage dans le passage (36) ce qui a pour effet de positionner correctement le détonateur axialement et de mettre en contact l'élément de verrouillage (28) et le détonateur (20) qui se trouvent ainsi tous deux bloqués dans le canal (28). L'invention porte également sur un procédé d'assemblage du détonateur (20) avec le bloc de connexion (10) pour obtenir un ensemble détonateur (20) bloc de connexion (10).
