ABSTRACT:
A bulb socket with a fastening structure for electrical contacts, which comprises a body portion and a secondary body portion to be welded together by means of a supersonic welding; inside the socket, there are screw threads for fastening a bulb. The bottom surface and one side of the body portion are furnished with two electrical contacts respectively; the electrical contacts on the side has two flat surfaces to be positioned in place with two rib plates respectively; the upper end of the electrical contact is held in place by means of a stop shoulder of the secondary body portion to prevent from pulling upwards; a resilient piece is furnished between two flat surfaces of the secondary body portion, and the resilient piece has a free end. Another electrical contact is inserted into a groove through the cover-fitting channel, and is bent into a bent plate above the bottom surface; the outer end of the bent plate is held in place by means of a positioning lug, which is horizontally positioned between the two electrical contacts to prevent the two from contact un-intentionally ( i.e., short circuited ).
