As shown in fig. 1 and fig. 2, the plug terminal 100 may include a tongue plate 1, a limiting member 2, and pins 3, the plug terminal 100 may include four pins as shown in fig. 2, in other embodiments, the plug terminal 100 may also include five or more pins, or less than four pins, and the number of the pins is not limited in the present disclosure. The tongue plate 1 may include a first tongue plate 11 and a second tongue plate 12, the second tongue plate 12 is connected to the first tongue plate 11, and the second tongue plate 12 is bent relative to the first tongue plate 11, so that the size of the entire plug terminal 100 in the length direction of the first tongue plate 11 may be reduced, which is beneficial to utilizing the space in the thickness direction of the female terminal device configured with the plug terminal 100. The pin 3 may include a conductive portion 31 and a transition portion 32 connected to the conductive portion 31, the transition portion 32 may be bent with respect to the conductive portion 31, the conductive portion 31 may be disposed on the first tongue plate 11, and the transition portion 32 may be disposed on a side of the second tongue plate 12 away from the first tongue plate 11 after being bent with respect to the conductive portion 31. The limiting member 2 may be connected to the second tongue plate 12, and the limiting member 2 may abut against each pin, so that the pin 3 may be limited between the limiting member 2 and the surface of the corresponding side of the second tongue plate 12. Therefore, when the opposite terminal is plugged with the plugging terminal 100, poor contact caused by the movement of the pin 3 towards the direction far away from the opposite terminal due to the friction force between the pins can be avoided through the limiting action of the limiting part 2, the stability in the plugging process is improved, and the probability of poor plugging is reduced.

The pin 3 may further include a soldering portion 33 connected to the transition portion 32, and the soldering portion 33 may protrude from an edge of the second tongue plate 12 to be soldered and conducted with a chip in the female socket device configured with the plug terminal 100.

In this embodiment, as shown in fig. 2, the second tongue plate 12 may include a first groove 121, and the limiting member 2 may be embedded in the first groove 121, so that the transition portion 32 may be abutted between the limiting member 2 and a bottom surface of the first groove 121, which may be beneficial to further reducing the size of the plug terminal 100 in the length direction of the first tongue plate 11. The first groove 121 may be formed by inward depression of a surface of the second tongue plate 12 on a side away from the first tongue plate, and the limiting member 2 may be in interference connection or clamped connection with the first groove 121.

Particularly, as shown in fig. 4, when the limiting element 2 is embedded in the first groove 121, that is, when the limiting element 2 is connected to the first groove 121, the surface of the limiting element 2 away from the pin 3 is flush with the surface of the second tongue plate 12 away from the first tongue plate 11, which is beneficial to the installation of the subsequent structural element.
