| Abstract: A device for rendering safe a detonator firing circuit by short
circuiting multiple conductors in the circuit includes a base portion and
cable piercing members. The base portion has a cylindrical block and
apertures for retentively receiving the cable piercing members. The cable
piercing member has a first end to impinge on and penetrate a cable
insulation when forcibly attached to an external surface of the cable.
The cable piercing member has a low electrical resistance and impedance
to generate a short circuit between conductors of the cable. Also, a
method for rendering safe a detonator firing circuit of by short
circuiting multiple conductor cables or a pigtail connector of a
detonator system. |
