ABSTRACT:
A conductor tube for a battery operated flashlight is disclosed. The conductor tube comprises an inner non-conductive sleeve positioned within an outer conductive sleeve. The flashlight bulb-receiving end of the conductor tube includes a plurality of inwardly disposed lances which extend from the outer conductive sleeve through the inner non-conductive sleeve to electrically engage the base terminal of the light bulb. The lances may extend longitudinally with respect to the conductor tube to securely receive the base of the light bulb of the flashlight. Alternatively, the lances may extend substantially circumventially about the end of the conductor tube to threadably receive the base of the light bulb and establish electrical continuity therewith. A method is disclosed for producing the conductor tube of the invention in a progressive die from a ribbon of laminated conductive and non-conductive materials which will, when formed, constitute the outer conductive sleeve and the inner non-conductive sleeve, respectively.
