The angle range of the second bending is between 87 and 89 degrees. The distance between the tails of the two groups of connection ends after bending is the same as the distance between the upper and lower groups of PCB holes. By bending the connection ends at the tail of the terminal for the second time and keeping the angle between 87 and 89 degrees after the second bending, the connection ends at the tail of the terminal are inserted into the two groups of PCB holes, and the connection between the connection ends and the PCB holes is an interference fit, so as to ensure the conductivity between the PCB board and the terminal. At the same time, this bending angle can ensure that there is a guiding effect when initially pressing into the PCB hole, ensuring that the harpoon terminal is correctly pressed in, facilitating the operator to install, eliminating the need for soldering connection, reducing the assembly cost, and improving the assembly efficiency and practicability.

[0008] Preferably, it further includes that an annular guiding groove is arranged on the outer side edge of the PCB hole; the insertion process of the connection end is guided by the annular guiding groove, reducing the insertion difficulty caused by the difference in the second bending angle of the connection end itself during the insertion process, and improving the practicability of the device.
