Description

A circuit breaker for preventing accidental electric shock to children

technical field

The utility model relates to the field of circuit safety, in particular to a circuit device for preventing accidental electric shock of children.

Background technique

Since electricity has been used by civilians, it has brought great changes to people's lives. While it is convenient, electricity is also very harmful to the human body. Once an electric shock is likely to cause casualties, especially children do not have sufficient awareness of electricity. If the live wire and the neutral wire in the circuit are touched at the same time, the current flows from the live wire through the human body to the neutral wire to form a circuit loop. If the live wire is touched only, the current flows through the human body and then flows into the ground to form a circuit loop. A circuit loop, that is, a closed loop, each loop must be closed to be effective. Simply put, a loop is a connected circuit. The current in a circuit must start from the positive pole and pass through the entire circuit. Of course, there must be resistance in the circuit, otherwise A short circuit will be formed, which will form a closed loop through all the electrical appliances and return to the negative pole. The AC loop starts from one phase and returns to another phase (industrial power) or back to the neutral line or ground (civilian power) through the circuit. The current socket is very easy to cause children to get an electric shock. Children are curious and will hold something inside a thin metal rod and insert it into the socket. The risk of electric shock is extremely prone to occur. Although electrical devices are equipped with circuit breakers, instantaneous electric shock cannot be avoided.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1, the utility model provides a technical solution: a circuit breaker for preventing children from accidental electric shock, including an insulating shell 1, a live wire circuit jack 2 is arranged on one side of the insulating shell 1, and the live wire circuit jack 2 is on the same side A neutral line circuit jack 3 is matched and installed, a circuit breaker 4 is arranged on the left side of the insulating case 1, a conductive metal block 5 at the far end is fixed inside the insulating case 1, and a conductive metal block 6 at the proximal end is fixed inside the insulating case 1, and One side of the conductive metal block 6 at the proximal end is connected to the zero line of the circuit, the left side of the conductive metal block 6 at the proximal end is connected to one end of the horizontal connecting rod, and the left end of the horizontal connecting rod is movably connected to one end of the vertical connecting rod through the pin shaft 8, and the vertical connection The upper end of the rod is connected to the surface of the outer ring of the rotating shaft 7, and the outer ring surface of the rotating shaft 7 is connected to the electric contact 11 through the connecting rod.
