Stable electric connection structure of vehicle-mounted electronic equipment

The utility model relates to the technical field of connecting devices, in particular to a stable electric connection structure of vehicle-mounted electronic equipment, which comprises a shell, a circuit board and a connecting end, and further comprises special-shaped metal strips which are symmetrically mounted on two sides of the circuit board and are 'C'-shaped, a cathode block and a reinforcing block are fixedly mounted at two ends of each special-shaped metal strip respectively, and the cathode block and the reinforcing block are connected with the shell. A metal elastic plate is connected between the two special-shaped metal strips, and when the negative electrode block is pressed, the two reinforcing blocks are far away from each other; the auxiliary reinforcing assembly comprises a sealing air cushion fixedly installed on the side wall of the shell and a piston pipe fixedly installed at the bottom end of the circuit board, and the piston pipe is communicated with the sealing air cushion.
