Abstract

A welding column combination includes at least two metal welding columns and at least one insulator block. Each metal welding column has a first end and a second end opposite to the first end, wherein at least one of the metal welding columns has welding surfaces at the first end and the second end respectively. The at least one insulator block assembles the at least two metal welding columns as a unitary physical combination.

Claims

1. A welding column combination comprising:

at least two metal welding columns, each metal welding column having a first end and a second end opposite to the first end, wherein at least one of the metal welding columns has welding surfaces at the first end and the second end respectively; and

at least one insulator block assembling the at least two metal welding columns as a unitary physical combination, wherein the insulator block comprises at least one insulation gap portion and at least two protrusion engaging portions, the insulation gap portion is configured to space adjacent-two of the at least two metal welding columns from each other.

2. The welding column combination of claim 1, wherein a height/width ratio of at least one of the at least two metal welding columns is greater than or equal to one.

3. The welding column combination of claim 1, wherein a height/width ratio of at least one of the at least two metal welding columns is less than one.

4. The welding column combination of claim 1, wherein a material of each metal welding column comprises copper, copper alloys, silver or silver alloys.

5. The welding column combination of claim 1, wherein a material of the insulator block comprises plastic.

6. The welding column combination of claim 1, wherein a height/width ratio of the welding column combination is less than two.

7. The welding column combination of claim 1, wherein each protrusion engaging portion has a width near the insulation gap portion less than a width away from the insulation gap portion.

8. The welding column combination of claim 1, wherein the at least two metal welding columns are of the same shapes or different shapes.

9. The welding column combination of claim 1, wherein each metal welding column has at least one through hole or concave slot configured to be inserted by a corresponding one of the at least two protrusion engaging portions.

10. The welding column combination of claim 1, wherein each protrusion engaging portion has a rectangular, semicircular or triangular cross section.

11. A power supply module comprising:

at least one circuit board; and

the welding column combination of claim 1 installed on the at least one circuit board and the welding surfaces of the at least two metal welding columns are welded to the at least one circuit board.

12. The power supply module of claim 11, wherein the at least one circuit board comprises a first circuit board and a second circuit board, wherein at least one of the at least two metal welding columns has the welding surface at the first end and the welding surface at the second end welded to the first circuit board and the second circuit board respectively;

or wherein the at least two metal welding columns have the welding surfaces at the first end and the second end.

13. The power supply module of claim 11, wherein the at least one circuit board is a printed circuit board or aluminum based circuit board.

14. The power supply module of claim 11, wherein a surface of the at least one circuit board is in contact with the welding surfaces of the at least two metal welding columns, and the surface of the at least one circuit board has at least one convex portion.
