Plug-In Lamp Holder and Lamp

A plug-in lamp holder, comprising:

• a lamp cap, an insulation base, a top cover, an L-pole conductive cap, an L-pole conductive spring, at least two N-pole conductive caps and at least two N-pole conductive springs,
• wherein the top cover is fixedly connected to the insulation base, the L-pole conductive cap extends from the bottom of the center of the insulation base for tight contact with an L-pole contact in a threaded lamp socket to realize electric conduction, the two ends of the L-pole conductive spring are compressed against the insulation base and the L-pole conductive cap respectively so that the L-pole conductive cap can be elastically stretched,
• wherein the lamp cap is sleeved and fixed on the outer wall of the insulation base, the lamp cap is isolated from the L-pole conductive cap by the insulation base, each N-pole conductive spring is electrically connected,
• wherein the side wall of the lamp cap is provided with at least two conductive cap holes, the side wall of the insulation base is provided with at least two accommodating grooves, the position of the conductive cap holes is adapted to the position of the accommodating grooves, the N-pole conductive springs are placed in the accommodating grooves, the heads of the N-pole conductive caps protrude outward from the conductive cap holes, the tails of the N-pole conductive caps are placed in the accommodating grooves and resist the N-pole conductive springs to compress them so that the N-pole conductive caps can be elastically stretched for tight contact with an N-pole threaded portion in a threaded lamp socket to realize electric conduction, and
• wherein when the plug-in lamp holder is connected to the threaded lamp socket (100), axial plugging and unplugging can be performed.
