Flat-belt type connecting mechanism, electric energy transmission device and motor vehicle

Abstract

The invention provides a flat-belt type connecting mechanism, and the connecting mechanism comprises a male end connecting mechanism and a female end connecting mechanism; the male end connecting mechanism comprises a flat belt, a flat terminal and a male end shell connected with the flat belt and the flat terminal; the female end connecting mechanism comprises double flat belts, a wire clamping terminal and a female end shell connected with the double flat belts and the wire clamping terminal. The male end connecting mechanism and the female end connecting mechanism are electrically connected with the wire clamping terminal through the flat terminal, and the male end shell and the female end shell are assembled and connected to form a flat-belt type connecting mechanism. According to the high-voltage charging wire harness, the flat belt is arranged in a laminated manner, and proper spacing is set, so that electromagnetic interference on other parts after the flat belt is electrified can be effectively reduced, and the purposes of eliminating a shielding layer structure of the high-voltage charging wire harness and reducing cost and weight are achieved.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a flat belt connection mechanism, an electric energy transmission device and a motor vehicle. Background technique [0002] The new energy battery of the new energy vehicle uses a charging system to supplement energy. In addition to the charging stand, the charging system also has a high-voltage flat belt connection mechanism connected to the battery system. The charging harness is the most important unit in the high-voltage system of an electric vehicle. The traditional charging harness uses copper wires as charging cables, and the ends of the copper wires are connected to Insert the terminal, and electrically connect with the battery system. The current high-voltage flat belt connection mechanism is an assembly structure connector, which has problems such as complex structure, difficult assembly, and high cost of the connector. In addition, the amount of copper used in cables...

AI Technical Summary

Problems solved by technology

The current high-voltage flat belt connection mechanism is an assembly structure connector, which has problems such as complex structure, difficult assembly, and high connector cost. In addition, the copper consumption of cables and terminals is high, and the connection processing is more complicated. It is also a high-voltage flat belt type. Reasons for the high cost of connection mechanism

[0003] When a large current passes through the high-voltage charging harness, it will cause electromagnetic interference to other components. In order to avoid this electromagnetic interference, it is necessary to add a shielding layer outside the high-voltage charging harness. This shielding of the high-voltage charging harness significantly increases the cost and weight
