The invention discloses a sealing ring, a sealing assembly, an electric connector and an electric automobile, the end face of one end of the sealing ring is provided with a first abutting part and a second abutting part, the first abutting part is arranged around the second abutting part, a first groove is formed between the first abutting part and the second abutting part, and the thickness of the first abutting part is larger than that of the second abutting part; the end portion of the first abutting portion protrudes out of the end portion of the second abutting portion in the axis direction of the sealing ring. According to the invention, the thickness of the first abutting part is greater than that of the second abutting part, and the end part of the first abutting part protrudes out of the end part of the second abutting part, so that the sealing compression size can be increased, and the guidance quality of the compression lip is improved, thereby avoiding sealing failure caused by outward turning; in addition, the overall sealing face of the first abutting part and the second abutting part is beneficial to compression, deformation redundancy of the sealing ring can be avoided, and safety is improved.
本发明公开了一种密封圈、密封组件、电连接器及电动汽车,密封圈一端的端面设有第一抵靠部和第二抵靠部,第一抵靠部环绕第二抵靠部设置,第一抵靠部和第二抵靠部之间具有第一凹槽,且第一抵靠部的厚度大于第二抵靠部的厚度;沿着密封圈的轴线方向,第一抵靠部的端部凸出于第二抵靠部的端部。通过采用本发明,第一抵靠部的厚度大于第二抵靠部的厚度并且端部凸出于第二抵靠部的端部,能够增大密封压缩尺寸,提升压缩唇口导向性,从而避免外翻导致密封失效;另外,第一抵靠部和第二抵靠部的整体密封面有利于压缩,能够避免密封圈变形冗余,提高安全性。
