Electrical connection device

An electrical connection device, comprising:

• a base;
• a terminal set disposed on the base, wherein the terminal set includes a plurality of terminals;
• a circuit board, wherein one end of each of the plurality of terminals is electrically connected to the circuit board;
• a switch unit electrically connected to the circuit board;
• a housing covering and enclosing the base and the circuit board;
• and
• a grip member, wherein the grip member is a hollow shell, the grip member has an actuating portion, the actuating portion is configured to actuate the switch unit, the grip member is disposed around the housing, the grip member is configured to be moved on the housing along an insertion direction and a withdrawal direction, and the insertion direction and the withdrawal direction are two opposite directions;
• wherein, when the grip member moves along the insertion direction and the withdrawal direction, the grip member is configured to control the switch unit to be turned on and off;
• and
• wherein, when the electrical connection device is plugged into or unplugged from a mating electronic device, conduction occurs only after complete plugging of the electrical connection device, and power is cut off before complete unplugging of the electrical connection device.
