CONNECTOR FOR ELECTRIC INITIATION DEVICES Russian patent published in 2016 - IPC F42B3/26 C06C5/04 

FIELD: blasting.

SUBSTANCE: invention relates to blasting works, specifically to surface of wiring layout for arrangement and reliable fastening in common housing detonating cap assembly with detonating cords with simultaneous contact of detonating cords with detonating and suitable to it shock-wave tube in detonation layout for performing of blasting operations. Connector for electric initiation devices comprises a body with a longitudinal central seat for detonating cap, which has four fixing protrusions and four longitudinal through holes, their diameter 10-20% larger than that of detonating cord. Holes are arranged uniformly around longitudinal central seat and are connected with central seat lengthwise slots. On body there is a flange with a recess of square section with four fixing protrusions on lateral sides of recesses and central cylindrical hole with diameter larger than that of shock-wave tube and which is connected with central seat. Depth of square of recess is equal to diameter of detonating cord, and size of side of square recesses equals three diameters of detonating cord. Connector protects initiating device well against unauthorised mechanical effects and high transmission of detonation of detonating cap to detonating cords or from detonating cord to shock-wave tube connected to detonating cap.

EFFECT: technical result consists in placing and reliable fixation in common housing detonating cap assembly with two detonating cords, as well as ensuring simultaneous contact of detonating cords with detonating and suitable shock-wave tube.
