[0021] In one embodiment of the present invention, reference Figure 1-2 As shown, a female plug for stabilizing current is provided, comprising a connector 10, a limiting ring 20 and a plurality of spring pieces 30. Each spring piece 30 is arranged in a circular array with the center line of the limiting ring 20 as the center, and the two ends of each spring piece 30 are respectively connected to the connector 10 and the limiting ring 20. The connector 10 comprises a connecting ring 11 and a connecting piece 12, one end of the connecting piece 12 is connected to the connecting ring 11, and the other end is connected to the wire. In this embodiment, the connector 10 is used to connect the wire. When the pin corresponding to the female plug for stabilizing the current provided by the utility model is connected to a female plug for stabilizing the current, the pin passes through the limit ring 20 and extends into each spring piece 30. Each spring piece 30 produces elastic deformation, exerts abutting force on the pin to prevent the pin from falling off. At the same time, the pin abuts against each spring piece 30 to transmit current. When the pin is inserted into each spring piece 30, the pin and each spring piece 30 are in contact at the same time to increase the contact area, reduce the resistance between the pin and a female plug for stabilizing the current, improve the transmission speed, and avoid heating when a large current passes through the connection end, which affects the service life and the current transmission speed and efficiency, and even causes burning.

[0022] Specifically, refer to Figure 1-2 As shown, the connecting piece 12 is provided with a wire hole 13 and a contact piece 14, one end of the contact piece 14 is connected to one side of the wire hole 13, and a gap for the wire to pass through is provided between the other end of the contact piece 14 and the wire hole 13. In this embodiment, the front end of the wire is peeled, then passed through the wire hole 13 and placed in the gap, the contact piece 14 is rotated to make the contact piece 14 contact the wire, and then the wire and the connecting piece 12 are welded to make the connection between the wire and the connecting piece 12 more firm.

[0023] Specifically, refer to Figure 1-2 As shown, a deformation gap is provided between two adjacent spring pieces 30. In this embodiment, a deformation gap is provided between two adjacent spring pieces 30, so that when the pin is inserted into each spring piece 30, the spring piece 30 has a deformation space to avoid mutual influence between the spring pieces 30, thereby causing the pin to be stuck.

[0024] Specifically, refer to Figure 1-2 As shown, the spring piece 30 is provided with an arched portion 31 and two connecting portions 32. Both ends of the arched portion 31 are connected to the two connecting portions 32, and the two connecting portions 32 are respectively connected to the connector 10 and the limiting ring 20. The two connecting portions 32 on both sides of the arched portion 31 are symmetrical to each other, and the arched portion 31 is arched toward the center line direction of the limiting ring 20. In this embodiment, when the plug pin is inserted into the middle of each spring piece 30, the arched portion 31 deforms to apply abutment force to the plug pin to fix the plug pin. At the same time, when the arched portion 31 is deformed, the plug pin contacts the connecting portion 32 at the same time, thereby increasing the contact area and reducing the resistance of the connection end, avoiding heating of the connection end when a large current passes through the connection end, affecting the service life and the current transmission speed and efficiency, and even causing burning.

[0025] Specifically, refer to Figure 1-2 As shown, a guide groove 33 is further provided on the upper surface of the spring sheet 30, and the guide groove 33 extends along both sides of the spring sheet 30 toward the center of the spring sheet 30 toward the lower surface of the spring sheet 30. In this embodiment, the guide groove 33 is used to guide the plug pin so that the plug pin can abut against the center of each spring sheet 30, thereby preventing the plug pin from rotating and scratching the surface of each spring sheet 30 to increase the resistance.

[0026] Specifically, refer to Figure 1-2 As shown, it includes four spring sheets 30, and the four spring sheets 30 are arranged in a circular array on the side of the center line of the limiting ring 20, and two adjacent spring sheets 30 are turned 90 degrees. In this embodiment, when the pin is inserted into the spring sheet 30, each spring sheet 30 is located in the upper, lower, left and right directions of the pin, so that the contact force on the pin is balanced.

[0027] Specifically, refer to Figure 1-2As shown, the connecting piece 12 is in an arc shape, and the radius of the connecting piece 12 is equal to the radius of the connecting ring 11. In this embodiment, the outer surface of the female plug for stabilizing current provided by the utility model is in an arc shape, and the connection end of the wire and the connecting piece 12 can be better protected.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
