Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a connector for high-power PCB power supply connection, comprising: a riveted copper column 100. A flower tooth 101 is provided at one end of the riveted copper column 100, and the flower tooth 101 runs through the outer surface of the riveted copper column 100. The flower tooth 101 is fixedly connected to the riveted copper column 100, and a backing groove 102 is provided at one end of the riveted copper column 100 close to the flower tooth 101, and a top surface 103 is provided at one end of the riveted copper column 100 away from the flower tooth 101.

[0022] In this embodiment, a back-off groove 102 is provided at one end of the riveted copper column 100 close to the flower tooth 101. By utilizing the special shape of the back-off groove 102, when the riveted copper column 100 and the stamping terminal 200 are riveted together, the excess material at the edge of the circular hole 201 provided on the stamping terminal 200 will enter the back-off groove 102 provided on the riveted copper column 100 under strong impact and extrusion, thereby forming a strong extrusion force, thereby axially fixing the flower tooth 101 and the riveted copper column 100, and the riveted copper column 100 will form a radially fixed connection with the stamping terminal 200. At this time, the flower tooth 101 remains stable on the riveted copper column 100, and the riveted copper column 100 and the stamping terminal 200 form a power supply connector for connecting the PCB board and the power supply cable to supply power to the PCB board.

[0023] Example 2

[0024] like Figure 1-Figure 4 As shown, a threaded hole 104 is provided on the riveted copper column 100, and a stamping terminal 200 is provided at one end of the riveted copper column 100 close to the flower tooth 101. A winding column 202 is fixedly connected to one end of the stamping terminal 200. A circular hole 201 is provided on the stamping terminal 200, and a smooth surface 203 is provided at one end of the winding column 202. Semicircular grooves 204 are provided on both sides of the stamping terminal 200.

[0025] In this embodiment, by opening semicircular grooves 204 on both sides of the stamping terminal 200, and using the semicircular grooves 204 to fix with corresponding connector guards, multiple power supply connectors can be fixed, so that the power supply connectors can be closely arranged.

At this time, one end of the pressure-riveted copper column 100 will enter the circular hole 201 opened on the stamping terminal 200, and the material at the edge of the circular hole 201 will be squeezed into the backing groove 102 opened on the pressure-riveted copper column 100, so as to radially fix the pressure-riveted copper column 100 and the stamping terminal 200, and fix the flower teeth 101 and the pressure-riveted copper column 100 axially. At this time, the pressure-riveted copper column 100 and the stamping terminal 2 00 connection is completed to form a complete power supply connector, and then the semicircular grooves 204 opened on both sides of the stamping terminal 200 are used to connect with the connector guard plate, and according to the power supply requirements of the PCB board, multiple power supply connectors are connected side by side on the power supply guard plate, and then the power supply cable is inserted from the inside of the box coil column 202 at the smooth surface 203, and finally, the bolts and the threaded holes 104 opened on the riveted copper column 100 are tightly connected to ensure that the PCB board and the power supply connector are stably connected, and finally the power supply of the PCB board is realized.
