Greater than the terminal portion and wire interconnecting piece point.
In order to be further improved technical solution, the outer wall of wire interconnecting piece of the present invention point starts tooth structure.
In order to be further improved technical solution, the end that wire interconnecting piece of the present invention is divided into is hollow open configuration,
It is connect with conducting wire, the end of terminal portion is hollow closed structure, and outer wall is plug construction；The liquid cooling terminal inner
Hollow space is divided into major diameter and two sections of minor diameter, is greater than the hollow straight of the other end with the hollow diameters of software wire connecting ends
Diameter passes through ring-shaped step between two sections and connects.
Connecting terminal is designed as hollow knot by the way that connecting terminal is internally provided with liquid cooling channel by the utility model
Structure is connected as one connecting terminal and software conducting wire, and the liquid cooling channel in the liquid cooling channel and software conducting wire that make connecting terminal is total
With such cooling medium enters the center of connecting terminal by the cooling inner tube of software conducting wire, then in the cooling for passing through software line
Out of connecting terminal is taken the high-temperature that connecting terminal generates in the return flow line formed between pipe outer wall and connecting terminal inner wall, then leads to
The cooling system that the cooling outer tunnel on software conducting wire is sent into outside cable is crossed, cooling outer tunnel is sent into the cooling system outside cable,
In such cyclic process, cooling medium can go out in the torrid zone sent out in cable and charging terminal work outside cable, not increase body
In the case where product, 600 amperes of electric current can be safely carried.Guarantee high-power charging pile special wiring terminal in the temperature of permission
Safe and reliable work in range.
