Abstract

A string lamp structure is provided, which includes a light bulb component, a lamp holder, a wire, and a lamp cover. The lamp holder is provided with a positive electrode elastic sheet and a negative electrode elastic sheet, the light bulb component is moveably connected to the lamp holder and electrically connected to the positive electrode and negative electrode elastic sheets. The wire horizontally passes through the lamp holder and abuts against the positive electrode and negative electrode elastic sheets, the lamp cover is movably connected to the lamp holder; when the lamp cover presses against the lamp holder, the lamp cover squeezes the wire, the positive electrode and negative electrode elastic sheets are caused to puncture the wire, thereby forming a conductive state. This way achieves a welding free process, significantly simplifies a production process, improves an overall production efficiency, reduces a production cost, and has strong practicality.

Claims (13)

1. A string lamp structure, comprising a light bulb component, a lamp holder, a wire, and a lamp cover;

the lamp holder is provided with a positive electrode elastic sheet and a negative electrode elastic sheet; the light bulb component is movably connected to the lamp holder and electrically connected to the positive electrode elastic sheet and the negative electrode elastic sheet; the wire horizontally passes through the lamp holder and abuts against the positive electrode elastic sheet and the negative electrode elastic sheet; the lamp cover is movably connected to the lamp holder;

when the lamp cover presses against the lamp holder, the lamp cover squeezes the wire, the positive electrode elastic sheet and the negative electrode elastic sheet are caused to puncture the wire, thereby forming a conductive state;

the positive elastic sheet is configured for connecting a live wire, and negative elastic sheet is configured for connecting a neutral wire;

the lamp holder is provided with a first placement chamber and a second placement chamber, wherein the first placement chamber is configured for installing the positive electrode elastic sheet, and the second placement chamber is configured for installing the negative electrode elastic sheet.

2. The string lamp structure according to claim 1 , wherein tops of both the positive electrode elastic sheet and the negative electrode elastic sheet are provided with sharp protrusions configured for puncturing the wire.

3. The string lamp structure according to claim 1 , wherein the first placement chamber is provided with a first clamping groove configured for fixing the positive electrode elastic sheet, and the second placement chamber is provided with a second clamping groove configured for fixing the negative electrode elastic sheet.

4. The string lamp structure according to claim 1 , wherein the lamp holder is further provided with a limit protrusion, and the limit protrusion is matched with the wire.

5. The string lamp structure according to claim 1 , wherein connection blocks are provided on two sides of a bottom of the lamp cover, and the lamp holder is provided with a protrusion portion corresponding to the connection blocks.

6. The string lamp structure according to claim 5 , wherein lower ends of the connection blocks are provided with a clamping protrusion, and the clamping protrusion is matched with the protrusion portion.

7. The string lamp structure according to claim 1 , wherein the lamp cover is further provided with a limit groove corresponding to the wire.

8. The string lamp structure according to claim 1 , wherein the lamp cover is further provided with a hanging hook portion.

9. The string lamp structure according to claim 1 , wherein an inner wall of the lamp holder is provided with a threaded portion, which is matched with the light bulb component.
