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 electrical signal to said electric igniter (16) and in particular three contacts (20), aligned with each other and dimensioned in relation to said printed circuit (18), ensuring connection between the tracks of said printed circuit (18) and the contacts (20) independently of the angular position of said shaped connector (12) with respect to said docking base.
A pyrotechnic installation comprising at least one firework (10), of the single-shot type, an electric igniter (16) and a docking base (13), a removable coupling system between said firework (10) and the electric igniter (16), a removable coupling system between the firework (10) and the docking base (13) and a removable coupling and electricity transmission system between the docking base (13) and the electric igniter (16), the firework (10) including a casing (11), in which the pyrotechnic components are housed, the casing (11) having an open first side and a second side with a shaped connector (12), the shaped connector (12) comprising a channel (15) connecting to the pyrotechnic components and housing the electric igniter (16), the electric igniter (16) comprising a pyrotechnic head covered by a protective cap equipped with a sealing area (29) and provided with contacts, the sealing area (29) constituting a hydraulic seal on the walls of the channel, the contacts being rigidly coupled to a printed circuit (18) of a PCB support (17), the printed circuit (18) comprising two concentric tracks, each connected with a contact of the pyrotechnic head of the electric igniter (16) and the printed circuit (18) being short-circuited, through a connection track between the two concentric tracks, the connection track being formed on a removable portion (19) of the PCB support (17), and being configured to remove short-circuiting by removing the removable portion (19), the shaped connector (12) being removably coupled, with freedom of rotation with respect to an axis passing through the center of the concentric tracks, to a docking base (13), the docking base (13) comprising the electronic components for transmission of an electrical signal to the electric igniter (16), namely three contacts (20), aligned with each other and dimensioned in relation to the printed circuit (18) ensuring connection between the tracks of the printed circuit (18) and the contacts (20) independently of the angular position of the shaped connector (12) with respect to the docking base.
