US12624936 - Separating primer cup of a propulsion module for a conducted electrical weapon

A conducted electrical weapon (“CEW”) deploys wire-tethered electrodes after generation of an ignition signal. The ignition signal is provided to a deployment unit. The deployment unit includes a primer material adjacent a conductor. The conductor conducts the ignition signal outside the primer material. A temperature of the conductor increases in response to receiving the ignition signal. The primer material ignites in response to the increase in temperature of the conductor.

conductedelectricalweaponprimercup

The patent describes a propulsion module for a conducted electrical weapon that features a primer cup designed to separate from an ignition cap upon ignition of the primer material. This separation allows for the movement of the primer cup away from the ignition cap, enhancing the deployment of wire-tethered electrodes.

Claim 1

1 . A propulsion module, comprising: an ignition cap, wherein the ignition cap comprises a base portion opposite an inner receptacle portion, and wherein the base portion comprises a larger radius than the inner receptacle portion; a primer cup coupled to the inner receptacle portion of the ignition cap; an ignition pin comprising a first end opposite a second end, wherein the first end is positioned within the primer cup, and wherein the second end extends through the base portion of the ignition cap; and a primer material positioned within the primer cup, wherein in response to an ignition of the primer material the primer cup is configured to separate from the inner receptacle portion of the ignition cap to permit a motion of the primer cup in a direction away from the ignition cap. an ignition cap, wherein the ignition cap comprises a base portion opposite an inner receptacle portion, and wherein the base portion comprises a larger radius than the inner receptacle portion; a primer cup coupled to the inner receptacle portion of the ignition cap; an ignition pin comprising a first end opposite a second end, wherein the first end is positioned within the primer cup, and wherein the second end extends through the base portion of the ignition cap; and a primer material positioned within the primer cup, wherein in response to an ignition of the primer material the primer cup is configured to separate from the inner receptacle portion of the ignition cap to permit a motion of the primer cup in a direction away from the ignition cap.
