Electrodes for electronic weaponry and methods of manufacture
A deployment unit for an electronic control device (ECD) used as a weapon provides a current from a signal generator of the ECD through tissue of a human or animal target. The deployment unit includes a housing, an interface, a filament, and an electrode. The interface couples the housing to the signal generator. The filament includes a first end coupled to the interface for receiving the current and comprises a second end. The filament conducts the current for inhibiting voluntary movement by the target. The electrode, stored in the housing prior to deployment, mechanically couples the filament to the target when deployed. The electrode includes an assembly of a first part and a second part that after assembly cooperate to bind the second end of the filament to the electrode.
1. An electrode for launching from a provided deployment unit toward a human or animal target to deliver a current through tissue of the target to impede locomotion of the target, a provided filament electrically couples the electrode to a provided signal generator to provide the current, the electrode comprising:
an aft part; and
a fore part; wherein
prior to assembly, the aft part is separate from the fore part;
the aft part mechanically couples to the fore part to form the electrode;
the aft part and the fore part remain mechanically coupled after launch of the electrode from the deployment unit toward the target to deliver the current;
while the aft part is coupled to the fore part, the aft part cooperates with the fore part to bind an end portion to the filament to the electrode, the electrode receives the current via the filament for delivery through the target to impede locomotion of the target.
2. The electrode of claim 1 wherein a surface of the aft part abuts a surface of the fore part to cooperate to bind the filament.
