ABSTRACT:
A miniature bulb assembly adapted to be mounted on a base board includes a socketless miniature bulb, a base portion molded of synthetic resin and a pair of terminal members. The miniature bulb is received in a bulb receiving hole at the central part of the base portion while a pair of lead wires extending from the miniature bulb are inserted through lead wire holes on the bottom wall of the base portion. Each terminal member comprises an elongated plate-shaped terminal and a base fitting portion, both of which are integrated with the base portion during a molding operation. The lead wires are connected to tongue-shaped pieces projecting from lead wire connection tabs in a clamped state. The base portion may be formed with T-shaped terminal insert holes on the opposite sides thereof such that terminal members each having a disengagement preventive tapered portion are tightly inserted thereinto from the above. Alternatively, the base portion may be formed with rectangular terminal insert holes on the opposite sides such that terminal members each having a fixed pawl are inserted thereinto from the bottom side of the base portion.
