Abstract: The present invention concerns a coupling and power transmission system for an electric igniter, in particular for single-shot type fireworks (10), the system comprising a casing (11), in which the pyrotechnic components are housed, said casing having a first side that is open and a second side with a shaped connector (12), said shaped connector (12) comprising a channel (15) for connecting to said pyrotechnic components and adapted to removably receive an electric igniter (16), said electric igniter (16) being rigidly coupled to a printed circuit (18) on a PCB support (17), the printed circuit comprising two concentric tracks which are short-circuited via a connection track on a break-away tab (19) of the PCB support (17), whereby removal of the tab (19) eliminates the short-circuit, said shaped connector (12) being couplable, in a removable manner and with freedom of rotation with respect to an axis, to a docking base (13), said docking base (13) comprising the electronic components for transmission of an e

Abstract: A timed pyric chain apparatus, particularly for the ignition of pyrotechnical fireworks includes a main conduit (2) for a retard fuse (16) the main conduit (2) having lateral branch conduits (5). The apparatus consists of coupled modular elements, each modular element having a fuse holder (1) including a main conduit (2) in which a retard fuse (16) is to be placed. The main conduit is divided into a first portion (4), the cross section of the first portion (3) being smaller than the cross section of the second portion (4), the fuse holder further including a lateral branch conduit (5) for receiving a wick (17) retainer (11) for a part of its length. The wick is provided with a fire passing sheath (18), the coupling of a first fuse holder (1) to a second fuse holder (1?) resulting from the introduction of the first portion (3) of the first fuse holder (1) in a second portion (4?) of the second fuse holder (1?).
