The object of the present invention is achieved like this: a kind of power connector, comprise power insert, signal plug-in unit, insulator and termination housing, be characterized in that described power insert is by connecting contact and being connected the tail end electrical connector forming of pegging graft, described connection tail end is " L " shape, and its one end is provided with plane of orientation and fixing cylindrical hole; Described connection contact one end is provided with and imports inclined-plane and the fixing face of cylinder; Described signal plug-in unit is " L " shape electrical connector; Described insulator is the connector seat that is provided with signal framing cavity volume, power supply location hole, brace cavity volume and picks and places plane; Described brace cavity volume is provided with " L " shape brace; Described power supply location hole and signal framing cavity volume connect and fix respectively power insert and signal plug-in unit; Described insulator and termination housing suit; Described brace one end is turned over to be riveting and is connect by riveting claw and insulator, and its other end is turned over to be riveting by rivet coating nut and insulator and termination housing and connects; In described termination housing, the termination height of power insert is lower than the termination height of signal plug-in unit.
Described fixing cylindrical hole port is provided with importing groove.
Described connection tail end is copper alloy plating tin.
Described connection contact is copper alloy plated with gold.
The present invention compared with prior art has the function of " make-before-break " and hot plug, from frame to the dead ground of PCB plate, guarantee the power supply circuit safety of electronic equipment, simple in structure, package dimension is little, low cost, realization is welded to plate and Through-hole reflow picks and places, and is especially applicable to pcb board hot plug and uses.
