Abstract
The utility model discloses a safety device for a detonator. The utility model is formed by the superposition of two metal sheets. When the safety device is used, two detonator wires are gripped, so that the detonator wires are always in a short circuit state. Accordingly, the safety of detonator use is enhanced.
Description
The utility model relates to a kind of safety device, specifically belongs to the detonator safety device.
At present, the market detonator all is in short-circuit condition when selling, and can prevent because electrostatic interaction makes its ignition.But its lead-in wire must be linked to each other with the big gun line in use.At this moment, when soon detonator is put explosive into, there is an open circuit time difference.As meet static or high-voltage line discharge, and it is ignited, will bring massive losses.
The purpose of this utility model is to design a kind of safety device, makes detonator be in short-circuit condition all the time.
This detonator device safe in utilization is made up of two metal sheets, connects overlapping by intermediate connection point.Sheet metal has the ripple bar of clamping two detonator lines in the tie point both sides.Because this safety device is when detonator docks with the big gun line and puts into explosive, two lead-in wires are in short-circuit condition all the time, thereby, improved the security when detonator uses greatly.
Accompanying drawing, detonator use peace one apparatus structure diagrammatic sketch
Embodiment: as shown in drawings, this safety device is formed by tie point (2) is tightly overlapping by two electric conductivity, elasticity rectangle copper sheet (1) preferably, and ripple bar (3) is located at tie point (2) both sides.During use, two detonator lines (4) are clipped in ripple bar (3) locate, both can keep detonator (5) to be in short-circuit condition in use all the time.
Claims (1)
1, a kind of detonator device safe in utilization is made up of two metal sheets, it is characterized in that two metal sheets is overlapping, is connected by intermediate connection point, and the sheet metal of tie point both sides is provided with the ripple bar, ripple bar place's clamping two detonator lines.
