COUPLING DEVICE FOR BLAST INITIATION SYSTEM (VERSIONS) Russian patent published in 2000 - IPC

FIELD: means for blasting. SUBSTANCE: coupling device for transmission of blast initiation non-electric signal from donor line to acceptor line, for example, input stub has a means of confinement of the donor line for bringing the donor line to signal transmitting coupling to the input stub. For confinement of the input stub in the point, where it is in contact with the donor line, use is made of a stop element. The coupling device has a part of the body, which accommodates and holds the primer detonator actuated after reception of a detonation signal from the input stub, - may be after a certain time delay, provided time-delay elements are located in the primer detonator. The coupling device has holding spring clamps for confinement of the donor line in signal transmitting coupling to the input stub, as well as a holding element of the output line, which confines the output line in signal transmitting coupling to the primer detonator. EFFECT: enhanced reliability of coupling of the donor line and acceptor line, providing for stable operation of blasting devices. 26 cl, 28 dwg
