[0002] The connector is an essential part for two electronic components or two electrical devices to achieve electrical connection. The connector generally includes plastic parts and metal terminals. The plastic parts and metal terminals are often integrated into a structure by injection molding, and the general connector uses double-row terminals to achieve multi-signal terminal high-current signal transmission. During injection molding, the metal terminal is generally cut into independent single pieces in the form of a continuous strip through a cutting structure, and then inserted into the injection mold for injection molding to obtain the plastic terminal body.
