Abstract
A unitary adapter for attaching a cutting nozzle to a laser cutting head includes an inner cylinder made of ceramic, a conductive shield sintered to the outer sidewall of the ceramic cylinder, a threaded conductive holder (for accepting the cutting nozzle) mounted in an opening at one end of the ceramic cylinder, and a coaxial connector (for connection to external measuring equipment) attached to an opposite end of the ceramic cylinder. A pair of wires is formed to be embedded within the ceramic material and provide separate electrical connections between the coaxial connector and: (1) the threaded holder, and (2) the conductive shield. The various components are sintered to the ceramic body to form permanent attachments, creating a unitary structure less susceptible to the high levels of acceleration and elevated temperatures associated with the laser cutting process.
