Description

technical field [0001] The invention belongs to the technical field of storage devices, and specifically relates to an output end structure of a three-in-one device of a DCDC, an oil pump frequency converter, and an air pump frequency converter. Background technique [0002] With the increasing shortage of energy, energy conservation and emission reduction has gradually become the new focus of people after dinner. As a major energy consumer, automobiles are closely related to people's livelihood, environment and development. The emergence of hybrid vehicles has provided a new development direction for energy saving of vehicles, and has gradually become the object of attention. [0003] Hybrid cars are different from ordinary cars. They need a DCDC converter that changes from a high-voltage battery to a low-voltage battery. This DCDC converter is characterized by a wide input range, large output current, and high power. The general output current is 100A~ Between 150A, this...

Problems solved by technology

[0004] At present, the output terminals of the three-in-one device of DCDC, oil pump inverter and air pump inverter of some hybrid vehicles are connected by bolts, and the output terminals are directly extended to the output of the three-in-one device of DCDC, oil pump inverter and air pump inverter. Terminal structure external wiring, this form has no effective protection for the terminal, no strict seal, the output terminal is susceptible to electromagnetic and slag interference from the external environment, affecting the use effect and service life

Moreover, the external wiring of the output structure of the three-in-one device of DCDC, oil pump inverter and air pump inverter takes up a lot of space, which is not conducive to saving the limited space of the car

[0005] Generally, when connecting cables, a skilled electrician removes the insulation on the surface of the cable and performs the connection. The cable is too short to connect, on the other hand, the operation speed is slow, and the exposed area of ​​the wire core is large, which increases the danger
