Abstract

The present disclosure provides an electrical connection structure, a charging socket and an automobile, in which the electrical connection structure is applied to a circuit board, and the circuit board is provided with a plug-in hole. The electrical connection structure comprises a metal dome and a plug-in terminal, in which the metal dome includes a base band and a plurality of elastic sheets respectively connected to the base band, the base band is wrapped around at least a portion of an outer periphery of the plug-in terminal, the elastic sheets have a protrusion portion which protrudes outwards, and the protrusion portion abuts against a surface of the circuit board, and the plug-in terminal is electrically connected to the circuit board by means of the metal dome. Based on the electrical connection structure of the present disclosure, the plug-in terminal has good contact with the metal dome, the metal dome has a protrusion portion which protrudes outwards and is stably connected to the circuit board, and the plurality of elastic sheets provide a plurality of signal detection points, thereby ensuring stability of signal transmission. In addition, the metal dome itself has good performance, can be used for multiple times of insertion and removal of the plug-in terminal, and has a long service life.
