DESCRIPTION OF THE EMBODIMENTS

[0022] In conjunction with drawings, further illustration on the present invention will be given in the following.

Embodiment 1

[0023] As shown in FIG. 1, an LED lighting includes an LED lamp 3, a connecting wire 1, and a connecting copper sheet 2 used to connect the LED lamp 3 and the connecting wire 1.

[0024] As shown in FIG. 1, the LED lamp 3 can be an LED light bar, an LED bulb or a simple light-emitting diode. The LED lamp 3 has two leading-out pins: positive and negative. The pins are electrically connected through the connecting wire 1 and the external power supply charges LED lamp 3 through the connecting wire 1.

[0025] As shown in FIGS. 2 to 4, the connecting copper sheet 2 includes a first fixing sheet 21 used to connect with the pin 31 of the LED lamp, the second fixing sheet 23 used to connect with the wire core 12 of the connecting wire 1, the third fixing sheet 24 used to connect with the sheath 11 of the connecting wire 1 and the copper strip 22 for connecting the first fixing sheet 21 and the second fixing sheet 23. The connecting copper sheet 2 is formed by integrated stamping and bending. After forming, the first fixing sheet 21 is C-shaped, and the second fixing sheet 23 and the third fixing sheet 24 are V-shaped. The length of the third fixing sheet 24 is longer than that of the second fixing sheet 23. The width of the third fixing sheet 24 is shorter than that of the second fixing sheet 23. The third fixing sheet 24 and the second fixing sheet 23 are concatenated, and the connection between the two is arc. As shown in FIG. 5, in order to realize large-scale automated production, the connecting copper sheet 2 is continuously produced by a long copper strip to form a continuous connecting copper sheet, that is, the adjacent connecting copper sheets are parallelly concatenated by the copper strip.

[0026] In the assembling process, the continuous copper strip 22 is cut and the corresponding fixing sheet is bent. Besides, the continuous connecting copper sheet connects a plurality of LED lamps 3 in series to form lighting decorations such as Christmas lights. Based on the structure of the connecting copper sheet of the present invention, the automatic production of LED lighting decorations can be realized. The connecting copper sheet 2 is sheathed with an insulating sleeve 4, and the insulating sleeve 4 is heat-shrinkable. The heat-shrinkable sleeve can not only protect the connecting copper sheet 2 from the electrical short circuit but also enhance the mechanical connection strength among the connecting copper sheet 2, the pin 31 and the connecting wire 1.

[0027] The first fixing sheet 21 of the present invention is formed into the C shape, and the shape is similar to that of the pin 31, which facilitates the insertion and positioning of the pin 31, and realizes a reliable electrical connection with the pin 31 and the connecting wire 1 after riveting. The second fixing sheet 23 is formed into the V shape, and the wire core 12 of the leading-out wire can be clamped to ensure the electrical connection between the connecting copper sheet 2 and the leading-out wire. The third fixing sheet 24 is formed into the V shape. After riveting, the sheath 11 of the connecting wire can be clamped to ensure the mechanical connection between the connecting copper sheet 2 and the connecting wire 1, and to prevent the wire core 12 from being separated from the connecting copper sheet 2.

Embodiment 2

[0028] As shown in FIGS. 6 and 7, what is different from Embodiment 1 is that the connecting copper sheet includes the first fixing sheet 21, the second fixing sheet 23 and the third fixing sheet 24. The first fixing sheet 21, the second fixing sheet 23 and the third fixing sheet 24 are concatenated in series. The length of the third fixing sheet 24 is longer than that of the second fixing sheet 23. The length of the second fixing sheet 23 is longer than that of the first fixing sheet 21. The width of the third fixing sheet 24 is shorter than that of the second fixing sheet 23. The width of the second fixing sheet 23 is shorter than that of the first fixing sheet 21. The first fixing sheet 21, the second fixing sheet 23 and the third fixing sheet 24 are all V-shaped or U-shaped. In order to realize large-scale automated production, the connecting copper sheet 2 is continuously produced by a long copper strip to form a continuous connecting copper sheet, that is, the adjacent connecting copper sheets are serially concatenated by the copper strip. In the assembling process, the continuous copper strip is cut and the corresponding fixing sheet is bent.
