Embodiment Construction

[0032] The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention. Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that product manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as the way to distinguish components, but use the difference in function of the components as the criterion for distinguishing. The subsequent description of the specification is a preferred implementation mode for implementing the present invention, but the description is for the purpose of illustrating the general principles of the present invention, and is not intended to limit the scope of the present invention. The scope of protection of the present invention should be defined by the appended claims.

Abstract

The invention relates to a PCB (printed circuit board) type low-voltage semiconductor-bridge ignition assembly which comprises a semiconductor-bridge transducer chip, an ignition charge, a main circuit board and a PCB. The main circuit board and the PCB form a T-shaped circuit board connection structure. The semiconductor-bridge transducer chip is fixed to the PCB through conducting resin or bonding wires. The ignition charge is packaged through a plastic sleeve. A pair of horse-head-shaped copper discharge plate structures with saw teeth covers the back of the PCB; each of the discharge plates is provided with at least two saw teeth facing the circumference; the saw teeth are of angle of 50-80 degrees. The ignition assembly can meet requirements of low ignition voltage, high electromagnetism safety, short ignition time, small size, firm structure and the like.

Description

technical field [0001] The invention relates to a semiconductor bridge pyrotechnic product, in particular to a semiconductor bridge ignition component with miniaturized volume, which can reliably ignite under the input condition of low ignition voltage. Background technique [0002] With the rapid development of electric detonators in the field of engineering blasting applications, the electromagnetic environment used by electric detonators is getting worse and worse. The radiation and interference of static electricity, electromagnetic waves, stray currents, etc. generated by the electromagnetic environment are getting stronger and stronger, and the electromagnetic environment is getting worse. The more complex it is, the higher the requirements for the anti-static, anti-electromagnetic radiation, and anti-stray current capabilities of industrial electric detonators during production, transportation, storage, and use. However, the thermal bridge wire ignition element used i...
