RU95105321A - Unit for laying-out of low-energy detonating cords - Google Patents

Abstract

FIELD: members of surface laying-out of low-pulse initiating cords-waveguides of the NONEL type or percussion case primers applicable for laying out of firing circuits in mining and construction, particular, in confined and power available conditions. SUBSTANCE: laying-out unit is designed for combined location and attachment in common body of primer detonator with primary length of cord-waveguide and several secondary lengths of cord-waveguide to obtain their connection with standard quality not affected by the external conditions and proficiency of the operator. Laying-out unit has cylindrical body in form of sleeve with perforated bottom, whose upper part is made in form of blades separated by grooves having radial projections-catchers and retaining ring. Body has flange located at a distance of blade length from its upper part. Blades are made with section reducing in height. Retaining ring is made in form of sleeve with through recess of varying width in bottom and has flange on the side opposite to bottom with hole whose diameter is smaller than the diameter of sleeve hollow. EFFECT: higher efficiency.

Claims (1)

The invention relates to surface wiring elements of weak-pulse initiating cords-waveguides of the type "Nonel" or shock tubes and can be used for mounting blasting networks during blasting in the mining industry and construction, especially in cramped and energy-saturated conditions. The wiring block is designed for joint placement and fixing in the common case of the detonator capsule with the primary segment and several secondary segments of the waveguide cord and to obtain a standard quality connection that does not change from external conditions and does not depend on the qualification of the detonator. The wiring block contains a cylindrical body in the form of a glass with a perforated bottom, the upper part of which is made in the form of grooves separated by grooves, equipped with radial protrusions-grips, and a retaining ring. The housing is equipped with a flange located at a distance of the length of the petal from its upper part, the petals are made with a section decreasing in height, and the retaining ring is made in the form of a cup with a through groove of variable width in the bottom and from the side opposite to the bottom, is equipped with a flange whose opening diameter is smaller the diameter of the cavity of the glass.
