Electrical connector assembly

Abstract

This invention relates to an electrical connector assembly, wherein an adapter connector is electrically connected to the circuit board of an adapter device, and a mating connector is provided for the adapter connector of the adapter device to be electrically plugged in. The insulating base of the mating connector extends outward from one side of the base with a tongue plate, through which multiple terminals of the transmission terminal group pass. On one side of the multiple terminals, multiple mating sides are provided exposed outside the base for longitudinal insertion and removal with the adapter connector, and on the other side, multiple connecting sides are provided exposed on the tongue plate surface. A shielding shell is then covered outside the insulating base and the transmission terminal group. The two outer sides of the shielding shell are respectively provided with fixing parts, which can be movably assembled with the circuit board to facilitate longitudinal up and down insertion and removal of the mating connector and the adapter connector, and to facilitate assembly and disassembly.
