Used in Explosive Trains

STAINLESS STEEL RING. 125 INCH INSIDE OIA LOADED WITH. 057 GRAM LEAO AZIDE PRESSED AT 10,000 P S I 

When there is more than one lead as in Fig 6-1, each successive lead should be of a larger diameter so that the intensity or 

Fig 1-65 LOCATION OF LEAD-IN AND LEAD-OUT IN THE FIRING TRAIN. ARMED POSITION 

In some cases there is only one lead and it is located in a place of its own. Such an item is known as lead without a suffix in or out (See Fig 6-2 of Ref 23) (Our Fig 1-66) 

Accdg to Ref 23, pp 6-5 to 6-8), the leads can be either cup-type or non-cup-type The cup may be pre-flanged as shown in Fig 1-67 and then loaded with HE chge before being inserted in the fuze bulkhead where it is crimped in place, as shown in Fig 1-68.

Primers are used for the ignition of propellants and pyrotechnics. They are categorized as percussion primers, used mainly for the ignition of propellants, and stab primers, used in explosive trains of fuses and electric primers. 

Detonators are used to detonate high explosives. Stab detonators are initiated by sharp firing pins and are used in explosive trains of different types of fuses. Flash detonators are initiated by flames produced by safety fuses, primers, or delay elements. A special type of flash detonator ignited by the flame of a safety fuse is called a blasting cap. Detonators are primarily composed of three types of explosives including sinoxid mixtures, lead azide-based mixtures, and mercury fulminate-based mixtures.
