[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0021] See also Figure 1-3 In the utility model: an integrated large current splitting slot terminal structure, including a rear end body 1 and a front end body 2, the top of the rear end body 1 is connected to the front end body 2; the front end body 2 includes a plurality of spring strips 3, and the plurality of spring strips 3 are evenly distributed on the circumference and fixed on the top of the rear end body 1, and the plurality of spring strips 3 constitute a circular jack cavity, and the overall size of the jack cavity gradually increases from the middle to the upper and lower sides, and the jack cavity is sequentially provided with a guide portion 4, a docking portion 5 and a connecting portion 6 from top to bottom.

[0022] In the utility model, when in use, the terminal is composed of a front end body 2 and a rear end body 1, the rear end body 1 is a welding area, and the front end body 2 of the terminal is an elastic contact part. When connecting the terminal, the connected pin can be inserted into the circular socket cavity composed of a plurality of spring strips 3 in the front end body 2 to complete the connection. During the process, the docking part 5 is relatively protruding and can be stably fitted with the pin, and the spring strip 3 has a certain elasticity, which can allow the docking part 5 to fit with the pin more stably, thereby improving the connection stability. When producing the terminal, a tubular blank of a specific size can be customized, and then the blank is placed in a mold, and the inside of the tube is well positioned and supported. The tube is formed by the pressure of the mold, and the split grooves and slots are cut out by a customized machine, and the closing and fastener 8 assembly are automatically completed, thereby solving the problems of high processing cost and complex production process; and the conductive performance cannot meet the requirements under high-frequency vibration and plugging and unplugging conditions.
