[0006] The above-mentioned present application is a switch structure for improving the heat dissipation effect, wherein the upper terminal A phase connection row and the upper terminal C phase connection row of the circuit breaker are led upward, and the upper terminal B phase connection row is led out to the front and rear sides, so that the three phases are staggered, thereby reducing the electric force between the three phases; and the upper terminal B phase connection row is led out to the front and rear sides so that the connection row of each phase terminal can be immediately separated while ensuring the phase-to-phase and relative safety distance, thereby increasing the heat dissipation circulation space between the connection rows; making the heat dissipation airflow rise more smoothly.
[0007] In some embodiments, the upper pile head A-phase connection row includes an A-phase connection row 1 and an A-phase connection row 2; the end of the A-phase connection row 1 is provided with an A-phase elbow 1 bent to the left in a spoon shape, and the end of the A-phase connection row 2 is provided with an A-phase elbow 2 bent to the right in a spoon shape, and the A-phase elbow 1 and the A-phase elbow 2 are arranged face to face;
