A single-conductor positioning device on each or either lateral side of a bulb holder, wherein, a receiving seat is integrally formed on the side of the bulb holder and is comprised of two hook-like sidewalls opposite to each other and forming an inner slot and a central slit. The wall portions of the sidewalls on both sides of the central slit are further folded to form respectively hooks. A recessed surface is formed centrally on an inner wall of the inner slot. A plug with a base can be fitted in the receiving seat, and has vertical grooves for connecting with the hooks on the receiving seat. The plug has a clamping recess provided in opposition to the recessed surface to form together with the latter a conductor clamping-slot. Inserting of the plug into the receiving seat can firmly position the conductor at a central position on the lateral side of the bulb holder; engagement of the plug with the vertical grooves can prevent the central slit from pulling outwardly.

1. A bulb holder having a single-conductor positioning device extending from at least one lateral side thereof including a receiving seat comprising two spaced apart hook-like sidewalls bounding therebetween an inner slot and a central slit, said two hook-like sidewalls having end portions forming hooks; a first recessed conical surface formed on a wall of the bulb holder and located in said inner slot; a plug having a cross-sectional shape matching with cross-sectional shapes of said inner slot and said central slit, the plug having a base fitting in said receiving seat, the plug having grooves engaged with said hooks on said wall portions of said receiving seat, said plug has a second conical recessed surface facing said first recessed conical surface thereby forming a conductor clamping-slot for clamping a conductor wire therebetween.
