[0026] The conductive terminal 100 of the electrical connector provided by the embodiment of the utility model is provided with the plug-in terminal 1 and the wiring terminal 2 at the front and rear ends of the conductive terminal, respectively.

The connection between the plug-in connector and the conductive terminal 100 of the electrical connector can be completed by inserting the plug-in connector pin into the U-shaped spring piece 11, and the connection effect is stable, reliable, simple and convenient. When connecting the external wire to the conductive terminal 100 of the electrical connector, it is only necessary to peel the end of the wire, and then place the exposed metal wire on the U-shaped clamping piece 21, apply external force to bend the two sides of the U-shaped clamping piece 21 inward to compress the metal wire, and bend the two sides of the U-shaped connecting piece 22 inward to compress the wire insulation, and the connection between the external wire and the conductive terminal 100 of the electrical connector can be completed, and the connection effect is stable, reliable, simple and convenient.
[0027] like Figure 2 As shown, in some embodiments, the inner sides of the upper contact arm 111 and the lower contact arm 112 of the U-shaped spring piece 11 are stamped with an inwardly protruding contact point a. The inwardly protruding contact point a makes the contact between the U-shaped spring piece 11 and the plug pin of the plug connector tighter and more reliable, and can increase the clamping force of the upper contact arm 111 and the lower contact arm 112 of the U-shaped spring piece 11 on the plug pin.

After the conductive terminal 100 of the electrical connector is inserted from the rear port of the terminal hole in the connector housing, the retaining spring 15 abuts against the step in the terminal hole to prevent backward movement.
[0033] In actual operation, a stopper (not shown in the figure) can be formed by punching inward at the rear end of the plug-in end 1, and the stopper can abut against the rear end of the U-shaped spring piece 11 to stop and limit the U-shaped spring piece 11 to prevent it from sliding backward in the plug-in cavity A.

After the conductive terminal 100 of the electric connector is inserted into the terminal hole (the terminal hole is provided in the connector housing for installing the conductive terminal 100 of the electric connector), the positioning card plate 16 is used to cooperate with the slot provided in the front-to-back direction of the terminal hole for positioning, so as to prevent the conductive terminal from moving freely in the terminal hole and affecting the position of the plug-in end.
[0035] like Figure 1 and Figure 2 As shown, in some embodiments, a limiting plate 17 is provided at the front port of the plug end 1, and the limiting plate 17 is used to limit the pins of the plug connector.
[0036] like Figure 4 As shown, in some embodiments, the connector end 1 is bent into a square tubular structure, and corresponding protruding plates 18 and notches are provided on the edges of both sides of the seam. The cooperation between the protruding plates 18 and the notches can play a limiting role to enhance the stability of the connector end 1.
