Detonator assembly

Lower cap. The brass lower cap houses the major portion of the movement assembly and contains the setting pin and hammer spring. It is threaded internally at the forward end to receive the point detonator assembly... 

This bar keeps the detonator assembly from moving toward the firing pin... 

A BkPdr booster (AA) is housed below the detonator assembly...

Slide outer casing and detonator assemblies over the rod and into position against the rear piston.

Once initiating devices are connected to a cord or fuse they become assemblies, hence blasting cap assembly and detonator assembly. Detonating relays are assemblies of detonators connected in such a way that multiple charges are fired in parallel or sequentially as one explosive initiates another. 

Detonator Assemblies, Non-Electric for blasting Non-electric detonators assembled with and activated by such means as safety fuse, shock tube, flash tube or detonating cord. The[y] may be of instantaneous design or incorporate delay elements. Detonating relays incorporating... 

A real advance in the construction of delay detonators was made by Eschbach, who introduced delay compositions which evolved so little gas that there was no longer need to vent the detonator. This eliminated risk of pre-ignition of high explosive and also made it possible to provide fully waterproofed assemblies which gave delay times much more regular because of the removal of variable venting effects. Delay detonators of this type have now virtually superseded all others. 

Assembly commences with a plain detonator containing its base charge and initiating explosive. These detonators are held in plates and the processes are insertion of suitable delay elements, followed by pressing in the normal way. They are then checked by X-ray examination to ensure... 

Flash past. In assemblies such as delay detonators and military fuzes the possibility of an igniting flash by-passing a delay element. 

With a sharp knife cut around the detonator just below the lowest or second crimp mark where it is attached to the fuse assembly. This is most easily done by holding the knife firmly on the metal and slowly rolling the detonator-fuse assembly on a flat surface. See Figure 22. The soft metal of the detonator case cuts easily, allowing the detonator to be pulled off the nipple of the fuse assembly. 

Spread the points of the cotter pin safety to prevent accidental dislodging and then unscrew the fuse assembly of the frag grenade with pliers. The fuse may be saved for use as an improvised firing device or the blasting cap may be removed for other uses (see section on improvised detonators). ... 

The committee expects that energetics from fuzes and burster assemblies will be present in the feed to the TRBP under normal operating conditions. EDS II testing showed that decomposition of these energetics will occur in a controlled manner and that explosive or detonation events are very unlikely (Eco Logic, 2001f). 

Finding (Blue Grass) EFKE-2. Energetics from fuzes and burster assemblies will probably not be destroyed in COINS, and downstream equipment must be able to handle this situation. Explosivity tests conducted by the technology provider showed that these materials decompose in the TRBP environment rather than explode or detonate and that the TRBPs will accommodate the decomposition of these explosive materials.
