Patent ID: 7891296

Claim:
A method of producing an assembly of a connector block and a detonator suitable for retaining at least one shock tube adjacent to a percussion-actuation end of the detonator, the method comprising inserting a detonator into a connector block, said detonator having a percussion-actuation end and an outer wall provided with an inwardly directed recess at a position remote from said percussion-actuation end, and said connector block having a housing provided with a bore for receiving said detonator, as well as a shock tube retention means provided on the housing at an end of the bore adjacent to the percussion-actuation end of the detonator, said shock tube retention means defining with said housing a slot for receiving at least one shock tube and holding said at least one shock tube adjacent to the percussion-actuation end of the detonator; positioning the detonator in the bore of said housing so that the percussion-actuation end is positioned adjacent to said slot; and fixing the detonator in the housing; wherein the detonator is fixed in the housing by causing a body of material to flow plastically into said recess in the detonator and to harden therein to form a locking element fixed to said housing, thereby preventing accidental movement of said detonator within said connector block.
