All-metal lamp cap electric connection structure, positive/negative terminals and LED (light-emitting diode) bulb using structure

Abstract

The invention discloses an all-metal lamp cap electric connection structure. A positive electrode on a PCB (printed circuit board) driving plate corresponding to the lamp cap is provided with an intermediate groove, and a negative electrode adjacent to the lamp cap is provided with a side groove. A positive terminal is provided with a base, the side edge of the base is bent to form left and right positive soldering lugs, the base is inserted into the intermediate groove and is soldered and fixed by the aid of the left and right positive soldering lugs, the top edge of the base forms an introduction port, the base extends and is bent to form an elastic sheet into which the lamp cap positive electrode is inserted to form electric connection, and the elastic sheet is also inserted into the intermediate groove. A negative terminal is provided with an insertion sheet, the side edge of the insertion sheet is bent to form negative soldering lugs, the insertion sheet is inserted into a side groove and is soldered and fixed by the aid of the negative soldering lugs, the top of the insertion sheet forms an elastic part, the end of the elastic part extends to form force arm which abuts against the supporting surface of the PCB driving plate, and the front end of the force arm is bent to form a contact head on which the lamp cap negative electrode performs extrusion contact, thereby forming electric connection. The invention also discloses an LED bulb using the structure. The structure is simple, is convenient for assembly, and has the advantages of fewer components and low cost.

Description

technical field [0001] The invention relates to LED light bulbs, in particular to the electrical connection structure of the all-metal lamp cap in the LED light bulb, the positive and negative terminals in the electric connection structure of the all-metal lamp cap, and the LED bulb using the electric connection structure of the all-metal lamp cap. Background technique [0002] In the traditional technology, the lamp base of the LED light bulb and the driving board are connected by wires, and the two ends of the wires are respectively soldered to the lamp base and the driving board to realize electrical connection. This connection method makes the assembly operation troublesome, the connection is unreliable, the cost is high, and it is not suitable for automatic production. [0003] Although some electrical connection structures have been developed by the industry to facilitate the assembly and connection of the lamp holder and the driver board, the structure is quite compli...
