Embodiment Construction
[0066]With reference to the drawings, a single firework is shown, which is indicated by reference numeral 10. The single-shot firework includes a housing 11 for containing a fireshot. The housing includes a plastic tube. The housing 11 is completely open on one side and is coupled to the formed plastic connector 12 on the other side. The connector 12 can be inserted into the housing of the docking base 13 and can be anchored in the housing by means of an elastic guillotine locking mechanism with elastic fins 14. As will be explained in detail below, by inserting the shaped connector 12 of the single hair 10 into the housing of the docking base 13 from above, the flaps 14 of the elastic blade are first opened and then independently closed to secure the single hair 10 Ground is blocked to the docking base 13. The shaped connector 12 of the single hair 10 provides an axial passage 15 in its initial part. The axial passage 15 directly leads to the inside of the casing 11, and the pyrote...

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, saidshaped 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 componentsfor 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), ensuringconnection 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.
Description
Technical field[0001]The invention relates to a connection and power transmission system for electric igniters, especially for single-fire fireworks.[0002]The present invention relates to the field of electrical connections, especially those used in the fireworks industry.Background technique[0003]In the fireworks industry, two types of fireworks can be identified: aerial fireworks (especially fireworks commonly called "cannonballs") and ground fireworks (usually divided into "candles", "fountains", "torches", "mines", and "fireworks". comet").[0004]The purpose of the present invention is ground fireworks, especially those ground fireworks called "single shot" type internationally, which include comets, explosions, fountains and dramatic effects.[0005]As we all know, single-shot ground fireworks (also more simply described in terms of single shot below) consist of a tube that is open on one side and closed on the other side to accommodate launching fillers and colored explosive effe...
