All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, an anti-falling circuit board comprises a circuit board main body 1, clamping blocks 2 are connected to four corners of the circuit board main body 1, anti-collision blocks 3 are connected to four corners of the circuit board main body 1, backing plates 6 are connected to the top and the bottom of the anti-collision blocks 3, limit sliding grooves 4 matched with the clamping blocks 2 are formed in the inner sides of the anti-collision blocks 3, buffer springs 5 fixedly connected with the backing plates 6 are arranged at two ends of the limit sliding grooves 4, the clamping blocks 2 are located between the two buffer springs 5, and one ends, away from the backing plates 6, of the buffer springs 5 are propped against the clamping blocks 2.

According to the anti-falling circuit board disclosed by the utility model, the four corners of the circuit board main body 1 are protected through the anti-collision blocks 3, and as the anti-collision blocks 3 have a certain height, the anti-collision blocks 3 are firstly contacted with the ground when the circuit board main body 1 falls and pad the circuit board main body 1, so that the four corners of the circuit board main body 1 are prevented from being damaged due to collision at the four corners when the circuit board main body 1 falls to the ground, the middle position of the circuit board main body 1 is not easily damaged due to contact with the ground, and meanwhile, the buffer spring 5 also plays a role of buffering, so that the circuit board main body 1 is not easy to damage.
