Main purpose of the present utility model is to provide a kind of and reduces with the assembled height of circuit board and increase the power connector of splicing stability.

The utility model purpose is achieved through the following technical solutions: power connector is provided with insulation shell, terminal insertion slot and terminal, wherein insulation shell has solder side, and the terminal insertion slot runs through solder side from different positions, and terminal has a compensation height mutually and plants from different directions, make these terminals protrude out the weld part on composition surface all on same horizontal line, by this structure, the power supply source connector electrically connects with circuit board with the surface adhesive type welding.In addition, this insulation shell is provided with two composition surfaces adjacent to the both sides of solder side, and on the top of insulation shell and run through two composition surfaces and be provided with a positioning seat, the bottom surface of this positioning seat has a location projection at least, can be plugged in the default hole of circuit board.And one "  " shape covering is set on this insulation shell, and its relative both sides are fastened on two composition surfaces of insulation shell, and severs a plate-like piece in this relative appropriate position, both sides, outwards is folded into a fixed part, can be welded on the circuit board.

According to above-mentioned principal character, the terminal insertion slot is arranged with particular geometric shapes, and so that the insertion slot of at least three diverse locations to be provided, and these terminal insertion slots three vertex positions of being isosceles triangle are arranged corresponding plant of terminal for equal number.And when terminal is inserted in the terminal insertion slot with specific direction, be positioned at the terminal of the insertion slot of this isoceles triangle shape peak, be mutual inverted direction with the terminal in the insertion slot of these isoceles triangle shape both sides, make these terminals protrude out the weld part on composition surface all on same horizontal plane.

Compared with prior art, the utlity model has following advantage: can save the assembled height between terminal mould development cost and time, reduction power connector and the circuit board and improve the stability of winding between power connector and the circuit board.

Below in conjunction with drawings and Examples the utility model is further described.
