发明名称 CORD CONNECTOR FOR WINDOW BLIND
摘要 A cord connector for a window blind includes a cord hole having a large hole portion and two small hole portions each communicated with the large hole portion through a neck portion defined by two opposite engaging walls. The diameter of the large hole portion is larger than that of a cord used in the window blind, the small hole portions each have a diameter equal to the cord diameter, and the width of the opposite engaging walls is smaller than the cord diameter. When the cord connector is in use, the cords are respectively inserted into the small hole portions of the cord hole. If an external force exerting on the cords overcomes the resistances of the engaging walls, the cords will move from the small hole portions to the large hole portion and then escape from the cord connector.
