Abstract
The utility model provides a circuit board with an overvoltage protector, which comprises a main circuit board, an auxiliary circuit board, and the overvoltage protector. Electronic elements and components used for normal working are arranged on the main circuit board. First auxiliary contacts which are used for working normally and separately from the main circuit board are disposed on the auxiliary circuit board. The first auxiliary contacts are in electrical connection with the electronic elements and components. The auxiliary circuit board and the main circuit board can be fixedly connected with each other in a detachable mode. According to the circuit board with the overvoltage protector, the first auxiliary contacts used for burning and detecting information are disposed on the auxiliary circuit board so that when the production is finished, the auxiliary circuit board is eliminated, the usable area on the main circuit board is made to be increased, and the sizes of the first auxiliary contacts can be relatively increased as well; and thus the circuit board with the overvoltage protector overcomes the defects existing in circuit boards in the prior art that the size of each contact is small and the alignment to external equipment is difficult, and the production efficiency is improved.
