The present application relates to the technical field of connector, especially to an electric connector assembly. The electric connector assembly comprises a shell, a PCB adapter plate is arranged in the shell, two or more rows of non-ground cables are electrically and fixedly connected to the PCB adapter plate, two or more rows of connecting pads are arranged on the front and back surfaces of the PCB adapter plate respectively, each row of connecting pads comprises a row of signal pads and ground pads, the core wire of the non-ground cable is electrically and fixedly connected to the signal pad on the front surface, the conductive outer sheath is electrically connected to the ground pad on the front surface, the signal pad and the ground pad on the back surface are used for being electrically connected to the corresponding terminals of a PCB female plate or being electrically connected to the corresponding terminals of an adapter socket and then being electrically connected to the PCB female plate, the PCB adapter plate is internally arranged with a conductive circuit to correspondingly connect the connecting pads on the front and back surfaces of the PCB adapter plate, and the electric connector assembly further comprises a load bottom support which is locked and connected to the shell. The electric connector assembly can realize multi-row high-density wiring and greatly improve the performance of the connector.

The utility model relates to the technical field of mobile power supply, concretely relates to a mobile power supply. Mobile power supply includes casing, data line, charging interface and main control circuit board, charging interface and data line are installed in casing one end, and main control circuit board is installed in casing and is located in the one end close to charging interface and data line. Main control circuit board includes AC component region and DC component region, and AC component region is installed with AC component, and DC component region is installed with DC component, is provided with the isolation board on main control circuit board, and the isolation board isolates AC component region and DC component region. The isolation board can play the shielding effect, and the magnetic field produced by AC component and its circuit is blocked to the influence of DC component and its circuit, thereby guaranteeing that the direct current output by DC component and its circuit is more stable, reduces the bad influence to other components using direct current in mobile power supply, such as avoiding electronic equipment signal transmission error, performance instability and so on.
