Description

TECHNICAL FIELD

[0001] The utility model relates to electrical component technical field, especially a female terminal. BACKGROUND

[0002] The male-female plug-in terminal is a common element in electrical connection, and the plug-in connection of the male-female plug-in terminal achieves the effect of power supply or signal transmission. At present, the female terminal of the male-female plug-in terminal is usually a cylindrical structure, and the male terminal is usually a pipe column structure. The engagement effect is not good when the male terminal is plugged into the female terminal, thereby leading to poor contact effect. There is a risk of the male terminal slipping off the female terminal in the plugging process, and the instantaneous interruption phenomenon may occur, that is, the short-term interruption of current or signal transmission. SUMMARY

The inner wall of the front end of the plugging part is provided with an inverted bevel. The top of the plugging part is provided with a slit along the length direction. The top and bottom of the front end of the plugging part are provided with a strip-shaped opening along the length direction. The crimping part is integrally connected between the rear end of the plugging part and the material belt, and the crimping part is coaxially arranged with the plugging part.

[0006] Further, the plugging part is provided with a clamping groove on both sides, which is matched with the clamping convex on both sides of the male terminal. It is used for limiting the male terminal by cooperating with the clamping convex when the male terminal is inserted.

[0007] Further, the crimping part comprises a bottom sheet, a first riveting wing sheet and a second riveting wing sheet. The bottom sheet is semicircular and coaxially connected with the rear end of the plugging part. The first riveting wing sheet and the second riveting wing sheet are arranged on both sides of the bottom sheet in sequence, and the first riveting wing sheet and the second riveting wing sheet are curved towards the axis of the bottom sheet.
