Wire connecting device and method thereof

A wire connection method using a wire connecting device, wherein the wire connecting device is configured for connecting and electrically communicating a first electrical wire and a second electrical wire, the wire connecting device comprising:

• an electrical connector having a first end, a second end, and a concave portion between the first end and the second end, wherein the concave portion is configured for accommodating a second core wire of the second electrical wire;
• and
• a connecting member cooperating with the electrical connector and configured for guiding the first end and the second end of the electrical connector connected with the first electrical wire,
• the connecting member is provided with a lancet configured for piercing the first insulating housing of the first electrical wire to contact with a first core wire of the first electrical wire, a first guiding surface extending respectively from both sides of the lancet is configured for guiding the first end and the second end of the electrical connector,
• the method, comprising:
• providing the electrical connector and the connecting member;
• placing the second core wire of the second electrical wire on the concave portion of the electrical connector, and placing the first electrical wire on an opening of the concave portion of the electrical connector;
• and
• engaging the electrical connector and the connecting member to make the first end and the second end of the electrical connector inserting into a first insulating housing of the first electrical wire, resulting in the first electrical wire and the second electrical wire electrically communicated by the electrical connector.
