[0002] In the prior art, the power supply unit and the metal bar of the cabinet of the data center are electrically connected through a connector. In order to improve the current transmission capacity of the connector, in the prior art, the terminals of the connector usually adopt multi-layer staggered overlapping terminals, that is, the terminals include a plurality of terminal stacks stacked up and down. Each terminal stack is not only used to transmit current, but also has an elastic structure for providing elastic contact force, which leads to a complex structure of the terminal stack and difficulty in manufacturing, and also leads to excessive insertion force when inserting the mating terminal. Generally, the insertion force of the mating terminal is proportional to the cube of the thickness of the connector terminal.

[0003] In the prior art, there are some cases where the matching conditions between the mating terminals and the terminals of the connector are offset or tilted. However, the floating contact performance of the terminals of the existing connectors is poor. When the terminals are offset or tilted, the following problems will occur: "One side of the terminal is subject to large force, while the other side is subject to small force, or even no contact". This problem is more serious when the terminals are extremely offset or tilted, which seriously affects the product performance, resulting in large and unstable contact impedance of the connector products, and reducing the current carrying capacity of the connector products.
