ELECTRICAL CONNECTOR WITH IMPROVED TERMINAL GROUPS AND CONNECTOR ASSEMBLY HAVING THE SAME

An electrical connector includes an insulating body and a number of terminal groups. The insulating body includes a mating slot, a first notch and a second notch. The first notch and the second notch are symmetrically arranged on opposite sides of the mating slot. The terminal groups include a first conductive terminal, a second conductive terminal, a third conductive terminal and a fourth conductive terminal. Each conductive terminals includes a mating portion extending into the mating slot. With this arrangement, relatively more terminal groups can be provided, which is beneficial to improve the speed of data transmission. A connector assembly having the electrical connector is also disclosed.
