Abstract

An improved structure of an electrical connector generally includes a shielding enclosure, at least one insulation body, an upper transmission conductor assembly, and a lower transmission conductor assembly. The upper and lower transmission conductor assemblies include an upper grounding terminal assembly, an upper power terminal assembly, a lower grounding terminal assembly, and a lower power terminal assembly, of which each terminal assembly defines a soldering section, an extension section, and a contact section. The soldering section has a width from 0.35 mm to 0.45 mm and a thickness from 0.15 mm to 0.25 mm. The extension section has a width from 0.35 mm to 0.45 mm and a thickness from 0.15 mm to 0.25 mm. The contact section has a width from 0.195 mm to 0.295 mm and a thickness from 0.15 mm to 0.25 mm. With such an arrangement, electrical current loading of the terminals can be effectively increased to meet the need for a large current without increasing noise interference.
