It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0022] like Figures 1 to 7 As shown, Embodiment 1 of this utility model provides a high-voltage connector, including a housing 1, a power terminal 17, a power terminal 31, a first core 10, a second core 11, a first limiting component, and a second limiting component. The housing 1 includes a first mounting part 2, a second mounting part 3, and a third mounting part 4. The first core 10 is mounted on the first mounting part 2, the power terminal 17 is mounted on the first core 10, the second core 11 is mounted on the second mounting part 3, and the power terminal 31 is mounted on the second core 11.
[0023] The power terminal 17 has a first connecting portion 18 exposed in the first core 10, and the power terminal 31 has a second connecting portion 44 exposed in the second core 11. The first connecting portion 18 and the second connecting portion 44 are electrically connected inside the third mounting portion 4.
[0024] The power terminal 17 extends along a first direction, and the power terminal 31 extends along a second direction. The first direction and the second direction intersect. The first limiting component is used to limit the displacement of the power terminal 17 along the first direction, and the second limiting component is used to limit the displacement of the power terminal 31 along the second direction.
[0025] In this embodiment, the first limiting component can limit the displacement of the power terminal 17 along the first direction to prevent the power terminal 17 from wobbling along the first direction, and the second limiting component can limit the displacement of the power terminal 31 along the second direction to prevent the power terminal 31 from wobbling along the second direction. This prevents the distance between the power terminal 31 and the power terminal 17 from changing, prevents the power terminal 17 from being disconnected from the power terminal 31, and improves the stability between the power terminal 31 and the power terminal 17.
[0026] In this embodiment, the first direction is the extension direction of the power terminal 17, and the second direction is the extension direction of the power terminal 31.

When the second locking hole 32 of the power terminal 31 moves above the second locking block 35, the second elastic arm 34 swings upward, causing the second locking block 35 to be locked into the second locking hole 32.
[0044] In this embodiment, the second elastic arm 34 is provided to facilitate the second locking block 35 entering the second locking hole 32.
