Abstract

The invention discloses a welding-free screw lamp holder, which comprises an insulating base, a wire, a conduction cap, a metal thread shell and an insulating bush, wherein the insulating base comprises an external thread section and a cap fixing base which is provided with a through hole, the external thread section and the cap fixing base are relatively fixed and the cap fixing base is arranged on the external thread section, the upper end of the wire passes through the through hole is overlapped on the cap fixing base, the conduction cap is provided with an externally-protruding part, the upper peripheral edge of the metal thread shell extends to form a necking hole, the insulating bush is fixedly connected to the necking hole, the metal thread shell is threaded outside the external thread section, the insulating bush is sleeved on the conduction cap and presses against the externally-protruding part so that the conduction cap is tightly pressed against on the insulating bush, and the conduction cap is ensured to be in contact with the upper end of the first wire. The welding-free screw lamp holder has the advantages of realizing the welding-free purpose, and avoiding loosening because the conduction cap is in tight contact with the first wire due to threading without releasing.

Description

technical field [0001] The invention relates to a welding-free screw lamp cap. Background technique [0002] Conventional screw base, see figure 1 , which includes an insulating base, a metal threaded shell screwed on the outside of the insulating base, a conductive cap A mounted on the insulating base and a first wire B, the insulating base is provided with a through hole, and the first wire B The upper end is welded to the center of the bottom surface of the conductive cap A, and the first wire B passes through the through hole from top to bottom and enters the insulating seat. The traditional screw lamp cap has the disadvantages of high cost and environmental pollution due to the need to adopt a welding process. [0003] Aiming at the above-mentioned deficiencies, someone proposes a solution, such as CN200820046833.1, CN201020253812.4, CN201020288693.6, CN201020524412.2, CN201020554055.4 of the Chinese patent database. The through hole is set on the top of the insulati...
