The utility model relates to a circuit protection technical field discloses a circuit board protection architecture. Circuit board protection architecture includes the U type groove that has the accommodation space and supports and end the part, U type groove includes relative first folded plate in position and second folded plate, and connects the third folded plate of first folded plate and second folded plate, first folded plate has the mounting hole, only supporting, the part passes through the mounting hole with first folded plate is connected. Adopt the utility model discloses technical scheme, circuit board can set up in U type inslot to supporting under the effect that ends the part and the inner wall butt in U type groove. Adopt such design, the position of circuit board can obtain firmly fixed, therefore the phenomenon that the electronic components of circuit board on transportation or the great in -process of atress cause the circuit board drop or harm that can significantly reduce to compare prior art, the embodiment of the utility model provides a need not to punch on the circuit board, therefore be favorable to the intensity of improved circuit board.
