ABSTRACT:
A photoflash unit comprising a horizontal linear array of photoflash lamp enclosed within a one-piece housing member having a light-transmitting front portion folded-over a back portion containing a plurality of lamp-receiving cavities in which respective lamps are disposed. The housing is a formed sheet of plastic film having a linear fold disposed horizontally along the top of the array of cavities. A pair of lead-in wires from each of the lamps are connected to conductive circuit patterns on one side of a printed circuit board sandwiched between a set of tabs which run along the bottom of the front and back portions of the housing. The housing tabs are secured together and to the circuit board by a plurality of staples symmetrically disposed along the tabs. Each of the staples has a pair of legs extending through both the housing tabs and the circuit board, with the center region of each staple bearing against an external surface of one of the tabs and the staple legs being clinched onto an external surface of the other of the tabs.
