[0002] With the steady growth of the global economy and the continuous increase in residents' income, consumption power has significantly increased, providing a solid economic foundation for the game controller market. During periods of economic prosperity, consumers are more willing to invest in entertainment and purchase peripheral products such as game controllers. A good power supply module and a stable power supply system greatly enhance the gaming experience. Power connectors are electronic components used to connect power sources to electronic devices or circuits. To facilitate connector connection, the male and female ends of the connector are respectively U-shaped and plate-shaped. The plate-shaped end is inserted into the U-shaped end. When the U-shaped terminal is placed in the terminal slot, the chamfer of the terminal is exposed. The plate-shaped terminal is relatively large and is prone to crossing the pin during insertion, which can easily lead to terminal deformation or loosening. Therefore, this utility model proposes a power connector. Utility Model Content

[0004] This utility model achieves the above-mentioned objective through the following technical solution: A power connector includes a housing, a plurality of terminal slots distributed on the housing, and terminals connected to the terminal slots. The slot opening extends from the front of the housing to the upper end face of the housing. The lower end face of the housing is provided with a clearance opening communicating with the terminal slots. The lower end face of the housing is provided with two fixing slots communicating with the terminal slots. The terminal includes a U-shaped fixing part. A welding part is provided on one side of the horizontal part of the fixing part. A contact part perpendicular to it is connected to one side of the two vertical parts of the fixing part. A contact protrusion is provided on a pair of opposite surfaces of the two contact parts. A downward-opening limiting groove is provided on both side walls of the terminal slot. A limiting spring piece extending into the limiting groove is provided at the top end of the contact part.

[0005] Preferably, the inner wall of the terminal groove is recessed near the contact protrusion.

[0006] Preferably, the front and upper surfaces of the housing are provided with guide slopes at the opening of the terminal slot.

[0007] Preferably, the ends of both vertical portions of the fixing part are tapered.

[0008] Preferably, the top of the limiting spring is provided with an outwardly bent S-shaped bend.

[0009] The beneficial effects of this utility model are: the top end of the contact portion extends into the limiting groove, and the guide slope can guide the connected sheet terminal, so that the sheet terminal is accurately inserted between the two contact portions to prevent cross-pin; the top end of the contact portion is limited by the limiting groove, which can ensure the terminal position accuracy and improve the production yield.
