Problems solved by technology

[0005] When the charging plate moves up and down repeatedly, the high-current cable connected to the charging plate also needs to move repeatedly at the same time and bend continuously. Therefore, the cable is constantly bent, which is easy to wear and has a low service life.
In addition, in order to make

Abstract

The invention provides a rotary conductive joint device and a using method thereof. The rotary conductive joint device comprises a first rotary conductive unit, a second rotary conductive unit, an insulating sheath and a connecting limiting unit. The first rotary conductive unit comprises a first insulating protective cover, an insulating shaft, a first conductive connecting bar and a conductive mandrel; and the second rotary conductive unit comprises a second insulating protective cover, a second conductive connecting bar, a conductive loop and a conductive spring. According to the rotary conductive joint device and the using method thereof, the functions of rotation and electric conduction are achieved, the firmness and the electric conductivity of the structure can be guaranteed, and the insulativity and the safety during work can also be guaranteed. The rotary conductive joint device can be applied to the field of large-current motion transmission in the free lifting or moving process of an electric vehicle charging device, the safety of electric conduction and the appearance attractiveness of an electric conduction device are achieved, the current-carrying limitation of cableelectric conduction is avoided, and the bending service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of charging devices for electric vehicles, and in particular relates to a rotating conductive joint device and a using method thereof. Background technique [0002] At present, large vehicles such as electric buses mainly use charging bows for fast charging. Compared with traditional charging piles, the charging time of charging bows can be shortened from the original 3 hours to 15 minutes, which greatly shortens the charging time and makes electric vehicles It takes only 5 minutes for the bus to quickly replenish its power at the first and last stations. Therefore, the charging method of the charging bow is convenient for dispatching urban bus lines, reducing charging time and reducing the investment of public transport vehicles, and its application is becoming more and more extensive. [0003] Charging bow charging breaks through the limit of the maximum output current of a single gun of 250A stipulated b...
