The technical solution of the utility model is: a kind of socket contact terminal of power connector, it comprises body part, bossing, butted part, described body part is a planar structure, and body part is provided with and is used to realize the bossing that docks with plug contact terminal.
Below technique scheme is further explained:
Described bossing comprises contact area front end, contact area, contact area rear end, and contact area front end and contact area rear end are respectively the inclined-plane of upward slope formula, descending formula.
Described body part is provided with and is used for the fixed structure that is maintained fixed with socket base.
Described fixed structure is a draw-in groove, and described draw-in groove is arranged on the body part side.
Be connected by the coupling part between described body part and the butted part.
Described butted part is and the cable butted part.
Described butted part is weldering printed wiring board tail end structure.
Described butted part is a crimping tail end structure.
The utility model has the advantages that: the socket contact terminal of power connector of the present utility model, compare with traditional supply socket terminal, contact position is at boss, can reduce gold-plated zone like this, save cost, can form the cross-ventilation space between bossing and the pedestal plastic cement wall simultaneously, help heat radiation, be particularly suitable for the application scenario of big electric current.
