US 5,204,492 A · Low noise, low shrapnel detonator assembly for initiating signal transmission lines

Abstract

A detonator assembly is provided which increases versatility, reliability and safety by initiating any amount of signal transmission lines up to about 8 without emitting excessive noise or shrapnel which can cause cut off or safety hazards. The detonator assembly comprises a low strength detonator with a single charge of preferably lead azide. A high confinement connection block houses the low strength detonator and comprises a retention block in which the low strength detonator is inserted and a confining wall which surrounds the closed end of the low strength detonator. One to about eight signal transmission lines can be inserted through a gap in the confining wall and operatively confined adjacent the closed end of the low strength detonator.

Dependent claims

A low noise, low shrapnel detonator assembly for initiating signal transmission lines, comprising:

(a) a low strength detonator with a closed end and between about 75 to about 150 mg of explosives contained in said closed end;
(b) a high confinement connection block with a first and a second end which houses said low strength detonator;
(i) said first end comprising a retention block which holds said low strength detonator with said closed end exposed;
(ii) said second end comprising a confining wall extended from said retention block that surrounds said closed end of said low strength detonator, said confining wall having a gap through which one to a plurality of signal transmission lines can be inserted and operatively confined adjacent said closed end between said confining wall and said closed end.
