In order to solve the problem of complex connection structure between the shell fragment 2 and the housing 1 in the prior art, as shown in fig. 1 and fig. 2, this embodiment provides a socket structure, including:

Because the elastic sheet 2 has elasticity, the elastic sheet 2 can be used for keeping the natural fitting plug 9 by means of the elasticity of the elastic sheet 2, the fitting area of the elastic sheet 2 and the plug 9 is increased, and the problem that the fitting of the elastic sheet 2 and the plug 9 after riveting or welding is uncontrollable is solved.

Meanwhile, the end surface and the side surface of the elastic portion 21 are both provided with the spacing groove 213, so that the elastic portion 21 is divided into at least two sheet-shaped bodies capable of being elastically deformed independently, and the deformation space of the elastic portion 21 can be further increased and the resilience of the elastic portion 21 can be reduced. Even if one of the sheet-like bodies fails elastically, the remaining sheet-like bodies can be kept elastically abutted against the plug 9, and the connection stability between the plug 9 and the socket structure can be improved.

Meanwhile, the detachable connection of the elastic sheet 2 and the shell 1 can also avoid thermal deformation of the elastic sheet 2 caused by a welding process, so that the forming size error and processing error of the elastic sheet 2 are reduced, and the rejection rate of the socket structure is reduced. In addition, the plurality of independently elastically deformed pieces can reduce the contact resistance of the elastic portion 21 and the plug 9, and also improve the electrical performance and the current-carrying capacity.
