[0003] Currently, the most widely used connector on the market is the 16-pin Type-C connector, mainly used in mobile devices such as mobile phones, computers, and chargers. As users' demand for fast charging increases, the charging current has gradually increased from the traditional 5A to 8A, 10A, or even higher.
[0004] To improve the overcurrent capability of conductive terminals in connectors, the existing technology mainly involves changing the power terminals to cross-sectional contacts to increase the overcurrent capability.

[0040] The first intermediate conductive component main body 211 and the second intermediate conductive component main body 221 are disposed between the upper row terminal assembly 11 and the lower row terminal assembly 12.
[0041] The first intermediate conductive part 212 is located between the contact portion 1111 of the first upper power terminal 111 and the contact portion 1211 of the first lower power terminal 121, and the second intermediate conductive part 222 is located between the contact portion 1121 of the second upper power terminal 112 and the contact portion 1221 of the second lower power terminal 122. Specifically, the first intermediate conductive part 212 is applied between the contact portion 1111 of the first upper power terminal 111 and the contact portion 1211 of the first lower power terminal 121, and the first intermediate conductive part 212 is in contact with the contact portion 1111 of the first upper power terminal 111 and the contact portion 1211 of the first lower power terminal 121, respectively.

Current is transmitted through six terminals: a first upper power terminal, a first lower power terminal, a second upper power terminal, a second lower power terminal, the first intermediate conductive element, and the second intermediate conductive element.
