Problems solved by technology

[0008] However, in the prior art, almost all new energy vehicles face the problem of charging safety, that is, because the charging devices include cables for transmitting large currents, and the cables are generally combined with a number of metal wires. After the wire is welded to the metal connector part, a large amount of heat is likely to accumulate in the welding part due to welding technology problems, which poses a huge safety hazard, which also severely limits the amount of current transmission, which in turn affects the performance of new energy vehicles. development trend

Abstract

The invention discloses an ultrasonic welding electrical connector. The electrical connector comprises a metal connecting member and a cable. The cable is provided with a number of independent metal wires. The metal connecting member is provided with a welding surface for welding a number of wires. The method comprises the steps that concentration limiting is carried out on a number of metal wires, and the metal wires under concentration limiting are positioned on the welding surface; and the metal wires under concentration limiting and the welding surface are fused together through ultrasonicwelding. According to the invention, uncontrolled situations such as separation between the large number of wires are effectively avoided during the ultrasonic welding process; and all metal wires and the welding surface are completely hot-molten together to prevent reduced power supply transmission security of the electrical connector due to uncontrolled irregular shape.

Description

technical field [0001] The invention relates to an ultrasonic welding electrical connector, in particular to an ultrasonic welding electrical connector for transmitting power. Background technique [0002] New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles. [0003] A pure electric vehicle (Blade Electric Vehicles, BEV) is a vehicle that uses a single battery as an energy storage power source. [0004] Hybrid Electric Vehicle (HEV) refers to a vehicle whose drive system is composed of two or more single drive trains that can run simultaneously. The drive train is provided jointly. Due to the different components, layout and control strategies, there are many forms of hybrid electric vehicles. [0005] A fuel cell electric vehicle (Fuel Cell Electric Vehicle, FCEV) is a vehicle that uses hydrogen and oxygen in the air under the action of ...
