In childhood education, physics circuits and robotics teaching experiments, different electronic components and sensors are often used to connect into circuits. In the related art, the simple circuit is mostly connected by a welding panel plate, a dupont line and other connecting structures, which has certain requirements on the operation technology of operators. However, as the teaching objects are continuously aged, the welding mode brings great inconvenience and potential safety hazards to teaching experiments, and the DuPont wires with needles are not safe to connect and are not suitable for teaching objects of smaller ages. In addition, the welding method has low connection efficiency.
