Abstract

A cable connector assembly includes an insulating body and a cable. The insulating body includes a first terminal group and a second terminal group received in the insulating body. The first terminal group has a first terminal. The first terminal has a first soldering surface at one end thereof. The second terminal group has a second terminal. The second terminal has a second soldering surface disposed opposite to the first soldering surface. The cable has a first core wire disposed between the first soldering surface and the second soldering surface and soldered to the first soldering surface and the second soldering surface. The first terminal and the second terminal have same functions share the first core wire and are directly soldered to the first core wire.
