[0024] The utility model provides a socket for an electric vehicle charging socket.

[0025] like Figures 1 to 4 As shown, in one embodiment of the utility model, the plug socket for the electric vehicle charging socket includes a plug pin 100 and a reed 200 made by a machining process. The reed 200 is rolled from a strip and made by a stamping process, so as to realize batch production of corresponding components and effectively reduce production costs. A thin waist-shaped elastic conductive sheet 210 is riveted on one end of the reed 200. The waist of the elastic conductive sheet 210 shrinks inward, which can not only enhance the contact force when the plug socket is plugged in, but also increase the contact area. When the placement plug socket contacts the adapter plug socket, the situation that the two are only partially in contact due to reasons such as the plug-in direction occurs, thereby ensuring contact strength and elasticity. The inner wall of the conductive sheet 210 is provided with a plurality of limiting protrusions 211. The elastic conductive sheet 210 is elastically sleeved on the lower end of the plug pin 100. The limiting protrusion 211 and the outer wall of the lower end of the plug pin 100 are limitedly abutted and locked, and the elastic conductive sheet is limited and fixed to the lower end of the plug pin, which effectively increases the contact area, thereby ensuring the contact effect, and tightly connects the spring sheet 200 and the plug pin 100 to avoid falling off during use and affecting charging. The frame of the spring sheet 200 at one end away from the elastic conductive sheet extends axially and is divided into a plurality of petals by the slot 240 extending axially. Each petal is folded outward to form an outward-expanding trumpet-mouth structure 220 along the circumferential direction.

[0026] Specifically, it also includes a steel sleeve 300 sleeved outside the reed, the steel sleeve 300 is a cylindrical structure formed by rolling a strip, a barb structure 310 is provided at one end of the steel sleeve 300, and the bell-mouth structure 220 can be rotatably connected in the barb structure 310 to achieve fixation and shaping. In particular, the barb structure 310 includes a wedge-shaped barb and a matching barb groove, and the bell-mouth structure 220 is rotated to interlock / bite with the wedge-shaped barb and the barb groove to achieve fixation. A positioning fin 320 is provided on the steel sleeve 300, and a positioning groove 230 is provided on the reed 200. The positioning fin 320 is inserted into the positioning groove 230 for fixation, and both ends of the steel sleeve are fixed and locked at the same time. By simplifying the structure and achieving a cylindrical shape, effective mass production can be achieved.

[0027] Specifically, it also includes a waterproof ring 400, which is sleeved on the plug pin 100. The waterproof ring 400 is made by using a traditional injection molding process, with low production cost and high yield.

[0028] Specifically, it also includes a drum spring 500, which is rolled from a strip. The drum spring 500 is sleeved on the upper end of the pin 100, and the drum spring 500 is manufactured by a stamping process to achieve mass production, thereby effectively reducing production costs.

[0029] Specifically, the working principle and process of the utility model are as follows: a spring is made by a stamping process, that is, a thin waist-shaped elastic conductive sheet is riveted on one end of a spring made by rolling a strip, and the elastic conductive sheet is sleeved on the lower end of a pin made by a machining process, and a limiting protrusion on the inner wall of the elastic conductive sheet locks the outer wall of the pin, and a steel sleeve is sleeved on the other end of the spring, and the steel sleeve is fixed by inserting a positioning fin into the positioning groove of the spring, and the trumpet structure of the spring is buckled / bite-engaged with the inverted hook structure of the steel sleeve, a waterproof ring is sleeved on the pin, and a drum spring made by a stamping process is sleeved on the upper end of the pin.
