[0025] The outside plug-in male end inserted into plug-in cavity 13, through the elastic clamping on the outside plug-in male end by the first and second elastic parts, forms the plug-in cooperation between the outside plug-in male end, and through the elastic back pressure of the second elastic part 14 by the elastic back pressure part 4, the piercing part 3 is formed on the crimping part 2, and the piercing part 3 on the crimping part 2 is inserted into the wiring harness through the piercing part 3.

[0026] The utility model discloses a plug -in terminal, as the plug -in female end that is used with the plug -in male end, wherein the plug -in terminal also relates to the crimping part 2, the plug -in part 1 of general plug -in terminal, and the plug -in cavity 13 of the corresponding plug -in mouth 12 is also provided in the plug -in end b, and the first elastic part and the second elastic part that can be used for clamping the plug -in male end when the plug -in male end is plugged in are involved on the plug -in end b, and the elastic return pressure part 4 is designed on the position close to the second elastic part 14 to ensure the reliability of plugging, when the plug -in terminal is matched with the plug -in male end, the plug -in male end is directly inserted into the first elastic part and the second elastic part, that is, the first elastic part and the second elastic part are clamped, and the elastic return pressure part 4 provides a maximum elastic limit for the second elastic part 14, thereby ensuring the reliability of electrical connection during plugging. In addition, the utility model also relates to the piercing part 3 for the position of the crimping part 2, when the wire harness is pressed by the plug -in terminal, the piercing part 3 is inserted into the wire harness, that is, the piercing part 3 is inserted into the wire harness, which can further improve the electrical connection reliability between the wire harness and the plug -in terminal, greatly reduce the reliability of the virtual connection between the plug -in terminal and the wire harness, and the piercing part 3 is inserted into the wire harness, which can further ensure that the plug -in terminal and the wire harness are not easy to separate after being pressed.

[0027] As Figures 1-6 The crimping part 2 includes a riveting core area 21 for inserting the wire core of the wire harness and a riveting foot area 22 for inserting the wire harness without stripping, and the piercing part 3 is distributed in the riveting foot area 22, and the number of the piercing part 3 is multiple. The crimping part 2 is used for the wire pressing stage of the wire harness, and the multiple piercing parts 3 pierce the outer skin of the wire harness and are inserted into the wire core respectively, which can realize auxiliary pressing of the wire core part of the wire harness by the piercing part 3 during the pressing process of the crimping part 2 on the wire harness, that is, when pressing, the piercing terminal on the riveting foot area 22 can pierce the plastic shell skin of the wire harness, and realize firm holding on the wire harness without stripping the outer skin.

[0028] As Figure 1 、 3As shown in Figure 7, both ends of the first elastic part 11 of the plug-in end b are connected to the plug-in end b. The middle section of the first elastic part extends into the plug-in cavity 13 in a curved and extended manner. One end of the second elastic part 14 is connected to the plug-in end b, and the other end is a free end 141 structure. The part of the second elastic part 14 that bends and extends into the plug-in cavity 13 is distributed near the free end 141 structure on the second elastic part 14. During the insertion stage of the external plug-in male end into the plug-in cavity 13, the elastic back pressure part 4 forms a design to prevent external spring overtravel at the free end 141 position on the second elastic part 14. This design can further ensure the reliability of the plug-in end b and the plug-in male end when they are plugged in, and also further ensure the convenience of implementation of this utility model.

[0029] like Figure 1 , 3 As shown in Figures 7 and 8, in a more common or easier-to-implement approach for the elastic back pressure part 4, 1. the elastic back pressure part 4 can be an outer baffle formed on the insertion end b, the outer baffle having a flat surface structure; 2. a design scheme in which an abutment block is formed on the back side of the flat surface outer baffle relative to the bent extension portion of the adjacent second elastic part 14 toward the insertion cavity 13.

[0030] like Figure 1 , 2 As shown in Figures 4-6, the crimping foot area 22 includes first and second crimping walls distributed on both sides of the crimping foot area 22 for bending and crimping. The first crimping wall 222 has an angle c relative to the direction towards the crimping core area 21, and the second crimping wall 221 has an angle c relative to the direction away from the crimping core area 21. During the wire harness crimping stage, the bending and crimping of the first and second crimping walls towards the wire harness placement direction forms a limit on the wire harness on the plug terminal. The first and second crimping walls bending and crimping in the wire harness placement direction have two angles c arranged adjacent to each other. The crimping part 2, after crimping, can directly act on the wire harness, firmly pressing it against the wire harness to ensure that it will not come apart. That is, it will not appear to be pressed tightly when one side of the crimping wall presses against the other side of the crimping wall, but there will actually be a certain gap between the other side of the crimping wall and the wire harness. This may result in the crimping part 2 and the wire harness not being pressed very firmly, and thus they may come apart. At the same time, after crimping, the crimping part 2 is divided into two structures with beveled angles c for pressing against each other, making the crimped plug terminal more aesthetically pleasing.

The implementations described herein are not intended to limit the scope of the disclosure, which is defined by the appended claims. For instance, features often described in the context of one or more implementations can be interchanged among the implementations, and / or used in other implementations. Unless otherwise stated, the functions or tasks described can be performed in either the order described, or can be performed concurrently or in a different order. Certain implementations can omit one or more features described without departing from the spirit and scope of the disclosure.
