CONNECTING UNIT FOR BLASTING INITIATION DEVICES Russian patent published in 2018 - IPC F42B3/10 

FIELD: blasting operations.

SUBSTANCE: invention relates to blasting operations and can be used in the initiation and transmission lines of a detonation signal. Connecting unit comprises a cylindrical sleeve with a closed end with the possibility of locating and fixing the detonator, clamping elements for the initiation signal transmission lines surrounding the detonator working end. Clamping elements are made in the form of half-lines counter-shifted in the transverse plane with respect to each other and connected to cylindrical half-channels to locate the initiation signal transmission lines arranged symmetrically on the outer side of the sleeve and parallel to the detonator axis. Each semi-channel is provided with a pressure roller mounted on a ring rigidly fixed to the cylindrical sleeve. Rounded ends of the half-channels end outside the end of the detonator.

EFFECT: simplifies the design, reduces the size, increases the reliability of the initiation system.
