Abstract

The invention relates to a secondary insensitive type electric igniter(an electric igniter for short) adopting direct current ignition. The electric igniter consists of six parts, namely an electric ignition head, an ignition medicament, a sealing plate, an insulating sleeve, a tube and an insulating bushing, wherein the electric ignition head consists of a lead wire, an electrode plug, an igniter wire and a head medicament; the electric ignition head, the insulating sleeve, the sealing plate and the ignition medicament are arranged in the tube; anti-static discharging holes are formed in the lead wire of the electric ignition head; the insulating bushing sleeves the lead wire and a cylinder on the end face of the tube. According to the electric igniter, by the adoption of the new ignition medicament, the new head medicament and the improved medicament accommodating space, the optimization of the igniter wire structure and the improvement on the technology, the technical requirements on the resistance, the insulating resistance, the safety current, the ignition current, the burst degree and the static electricity prevention of the electric igniter and the requirement on energy output are met.

Description

technical field [0001] The invention relates to a sub-insensitive electric igniter (hereinafter referred to as the electric igniter) for direct current ignition, which is suitable for ignition devices for military and civilian pyrotechnics, and belongs to the field of electric pyrotechnics. Background technique [0002] In our country, with the rapid development of military technology, the demand for electric igniters is increasing, and the performance requirements for electric igniters are also developing rapidly. From the original civilian electric igniters to the current sea and land , aviation and other military fields. The existing electric igniters are divided into two types: sensitive type and insensitive type. The characteristic of sensitive type electric igniter is that the safety current is low, and the product is easy to catch fire during production, assembly or testing, and it is easy to cause losses to personnel and property. The insensitive electric igniter so...
