Photo-flash unit with horizontal lamp array - has multiple connector terminals adjacent one another on flat tab projecting from circuit board edge

摘要

The photoflash unit comprises a horizontal linear array of flashlamps enclosed within a one-piece housing having a light-transmitting front portion folded over a back portion containing lamp-receiving cavities. A printed circuit board is joined to the housing and a pair of lead-in wires from each of the lamps are connected to conductive circuit patterns disposed solely on one side of the circuit board. The circuit patterns include multiple connector terminals located adjacent one another on a flat tab which projects from one edge of the circuit board for insertion into the receiving socket of a firing pulse source. The tab contains symmetrical apertures or recesses, which render the tab releasably engageable by sockets independent of firing pulse contacts for securely retaining the unit in the socket.
