[0002] With the rapid growth of national promotion of new energy electric vehicles and market demand, the compatibility and reliability of charging facilities have become key challenges. Currently, charging sockets both domestically and internationally are mainly divided into AC and DC systems. However, the assembly process of existing AC / DC cables is complex and cumbersome, and after-sales maintenance is difficult and operation is not straightforward, increasing equipment complexity and cost, making it difficult to meet the integration requirements of compact charging piles. Therefore, this design addresses this issue. Currently, DC terminals are generally produced using a stamping method to reduce processes, improve production efficiency, and facilitate subsequent maintenance and after-sales service, as well as easy replacement. However, traditional stamped DC terminals still have disadvantages: poor strength and unsatisfactory stability after assembly. Utility Model Content

The front end of the cable welding surface has an upper positioning foot and a lower positioning foot. The sheath is fitted over the terminal body, with a front fixing foot that wraps around the contact at the front end and a rear fixing foot that wraps around the first fixing groove at the rear end; The clamping component consists of a left clamping sleeve and a right clamping sleeve. The side walls of the left and right clamping sleeves are provided with a second positioning groove for positioning the cable welding surface and a third positioning groove for positioning the upper positioning foot. The inner cavity is provided with a fourth positioning groove for positioning the lower positioning foot.

Detailed Implementation
[0013] Reference Figure 1-8As shown, the present invention discloses a terminal stamping type DC charging socket, comprising a housing 1, a DC terminal assembly 2 disposed within the housing 1, a bushing 3 disposed within the housing 1 for fixing the DC terminal assembly 2, and a rear cover 4 covering the rear end of the housing 1. The DC terminal assembly 2 includes an integrally stamped terminal body 5, a sheath 6, and a clamping member 7. The terminal body 5 has a set of circumferentially arranged contacts 8 at its front end, a cable welding surface 9 at its rear end, and a set of first fixing grooves 10 on its side wall. The cable welding surface 9 has an upper positioning foot 11 and a lower positioning foot 12 at its front end. The sheath 6 is fitted over the terminal body 5, with a front fixing foot 13 at its front end that wraps around the contacts 8, and a rear fixing foot 14 at its rear end that wraps around the first fixing grooves 10. Ideally, the sheath 6 is made of stainless steel to improve the tension and strength of the terminal body 5. The clamping component 7 consists of a left clamping sleeve 15 and a right clamping sleeve 16. The side walls of the left and right clamping sleeves 15 and 16 are provided with a second positioning groove 17 for positioning the cable welding surface 9 and a third positioning groove 18 for positioning the upper positioning foot 11. The inner cavity is provided with a fourth positioning groove 19 for positioning the lower positioning foot 12. During assembly, the fixing feet are inserted into the corresponding positioning grooves, thereby very stably fixing the terminal body 5 onto the clamping component 7 to form an assembly. Finally, the assembly is installed into the housing 1.
[0014] Preferably, the sheath 6 has a set of circumferentially arranged front latches 20 on its sidewall, and the left half clamping sleeve 15 and the right half clamping sleeve 16 have a set of circumferentially arranged rear latches 21 on their sidewalls. The housing 1 has a front locking platform 22 connected to the front latches 20 and a rear locking platform 23 connected to the rear latches 21 inside the housing. This structure enables a quick connection between the DC terminal assembly 2 and the housing 1.
[0015] Preferably, the housing 1 is provided with a heat-conducting sleeve 24 that fits against the upper positioning foot 11, and a thermal sensor 25 is provided inside the heat-conducting sleeve 24. The above cleverly utilizes the upper positioning foot 11 as a temperature rise detection point to achieve effective detection of the temperature rise of the DC terminal assembly 2.
[0016] Preferably, the left half of the clamping sleeve 15 is provided with a connecting groove 31, and the right half of the clamping sleeve 16 is provided with a hook 32 that connects to the connecting groove 31.
