Description

 A drug-free 引 electric ignition head

Technical field

 The utility model relates to an electric ignition head, in particular to a fast electric ignition head with high safety factor, stable performance, high use efficiency and no gunpowder.

Background technique

 In the fireworks industry, most large fireworks and some consumer fireworks use fast lead as the ignition lead, that is, several black medicine leads are wrapped in parallel in kraft paper. After the lead is ignited, the fireworks can be quickly ignited by dozens of times the burning speed of the safety lead, so that the quick-fired fireworks are often used for electric ignition.

 At present, the electric ignition head used for the electric ignition of the fireworks is a structure containing a gunpowder, that is, a small amount of gunpowder is wrapped on the resistance wire short-circuited at one end of the wire, and the gunpowder and the wire are passed through the adhesive and the moisture-proof agent. Fixed as one. When in use, the current is directed to a resistance wire that is shorted between the wires. The resistance wire heats up rapidly, which in turn ignites the surrounding gunpowder. The gunpowder burns to produce a flame and high temperature, further igniting the fireworks leads fixed around it.

 The electricity is occupied, and the fire part of the fire head is in the shape of a match head. In order to achieve the guilty contact with the quick lead, the user must cut the kraft paper of the quick lead to cut the electricity/occupation, insert the fire part of the fire head into the kraft paper, and the black lead. Direct contact, then tape the quick lead to the electric ignition head. The process is cumbersome and inefficient

 In order to improve the ignition rate of the electric ignition head, the gunpowder used is often a highly sensitive gunpowder, which causes the electric ignition head itself to be sensitive to friction or impact. It may trigger a dangerous number in the preliminary assembly process with the fireworks. Ten serious deaths and injuries caused by false triggering of the electric ignition head

 The oxidant component in the gunpowder has strong oxidizing power. Although the electric resistance wire used in the electric ignition head is an inert alloy wire, the electric resistance wire is gradually oxidized as the storage time increases or the storage ring is inferior. The heat generation performance drops sharply, and when the trigger temperature is not reached, it is melted from the oxidation link, and a misfiring phenomenon occurs.

 The electric ignition head contains gunpowder, which must be treated specially during transportation. Most countries do not allow air transportation of similar items, which greatly increases transportation costs and difficulty.

Utility model content The technical problem to be solved by the utility model is to provide a safety factor with the same safety factor, stable performance, high use efficiency and no ignition charge ignition head.

 In order to solve the above technical problem, the present invention provides a safe and efficient drug-free quick-ignition ignition head, comprising a circuit board, a wire pair, a resistance wire and a mounting clip, the resistance wire and the wire For the soldering on the circuit board, the front end of the mounting clip has a tongue-shaped plug for facilitating insertion into the quick-release, and the front upper block of the mounting clip is provided with a positioning pin corresponding to the inserted quick-input. The circuit board is fixed on the tongue-shaped plug, the resistance wire is upwardly facing and perpendicular to the direction of the fast-injection direction, and the pair of wires are led out along the rear end of the mounting clip and fixed. The front end of the upper and lower blocks of the front end of the mounting clip is provided with a closing card position, and the front end of the mounting clip is closed to each other by an external force and is fixedly connected along the closed card position.

 The mounting clip is composed of an upper cover and a lower cover, the tongue plug is disposed at the front end of the lower cover, and the tongue plug and the rear end of the lower cover are formed with a bend a notch, the tongue-shaped plug is provided with a circuit board slot, and a circuit board fixed card is disposed on both sides of the circuit board slot, and the circuit board fixing card is aligned and fixed on both sides of the lower cover The position of the position is provided with a latching position under the ignition, the rear end of the lower cover is provided with a wire positioning groove, and the rear end of the lower cover is provided with a wire clamping lower card position, and the circuit board passes through the The circuit board fixing card is fixed in the circuit board slot, the wire pair is fixed by the wire positioning slot; the rear end of the upper cover is provided with a wire closing upper card position, and the front end is provided with an ignition close The card cover, the upper cover and the lower cover are fixed by the wire to the lower card position and the wire is closed to form an integral mounting clip.

 The electric resistance wire is electrically coiled, and the electric resistance wire having good conversion capability is wound into a fine spiral shape. For the resistance wire with poor soldering performance, the plating layer can be soldered without affecting the heat generation performance.

 A hole is formed in a region of the circuit board corresponding to the heat generating portion of the electric resistance wire.

The most commonly used five-core quick-lead on the market is a lead made of five wool-impregnated cotton threads wrapped in kraft paper. The space occupied by kraft paper is larger than the five equal black leads because of the need to maintain a certain burning space. When used, Insert the tongue-shaped plug of the fixed circuit board in the clip into the gap, and keep the side of the circuit board with the resistance wire facing up and the resistance wire part The circuit board is inserted into the gap together, and the mounting clip portion inserted into the quick lead is fastened to the main body portion of the mounting clip, and is fastened to the main body portion, and the positioning pin of the main body portion of the clip is inserted into the quick lead. The fixed simultaneous crimping block presses the parallel black lead on the resistance wire of the circuit board. After the zero wire is energized to the resistance wire, the resistance wire heats up and directly ignites the inner lead wire in contact with it, thereby igniting the fireworks lead.

 -tic Because the whole electric power is occupied, the fire head does not contain gunpowder components, and it will not cause false triggering due to friction and impact, which ensures the safety in the production, storage, transportation and use of the utility model because there is no strong oxidation around the resistance wire. Sexual gunpowder, the long-term storage of the utility model does not affect the heating performance of the electric resistance wire, thereby ensuring the ignition performance of the utility model; since the reliable women's clothing of the quick-induction only needs to be inserted and pressed on the mounting clip No additional auxiliary materials are needed to ensure the efficiency of the utility model.

 In summary, the utility model is a fast electric ignition head with a safety factor of ί3⁄4, stable performance, simple structure, convenient manufacture, high efficiency and no gunpowder.
