Metal support whole structure

A metal support whole structure comprises an injection molding support and multiple metal contact pieces fixed to the support in parallel, wherein the surface where the metal contact pieces are installed, of the support, is a plane, and is higher than the surface of the injection molding support, and grooves are formed among the adjacent metal contact pieces. The grooves are formed among the adjacent metal contact pieces, so that the metal support whole structure enables volatile matter and residues produced by scaling powder and other substance to be smoothly discharged out and not to be attached to the metal contact pieces and the support, and the phenomenon that the functionality (such as contact and welding of metal contact pieces and external conductors) of the metal support whole structure is poor in follow-up usage is not caused. In addition, the surface where the metal contact pieces are installed, of the support, is the plane, burrs are not produced during forming, the phenomenon that the appearance is non-attractive does not easily occur, and the quality of the entire metal support whole structure is improved.
