Embodiment 1

[0034] like Figure 1-5 As shown, a new energy vehicle charging gun includes a gun body 1, the front end of the gun body 1 is fixedly connected with a plug 2, and the gun body 1 is provided with a cavity 3 and a cooling cavity 4, and the cavity 3 and the cooling cavity 4 are filled with There is an insulating liquid, and the insulating liquid can be transformer oil, which can not only play an insulating role, but also cool down the inside of the charging gun. The cavity 3 and the cooling cavity 4 are connected through the connecting channel 51, and the cavity 3 is provided with :

[0035] The conductive plate 31 is fixedly connected to the side wall of the cavity 3, and the conductive plate 31 is electrically connected to the plug 2;

[0036] Movable plate 32, the movable plate 32 is arranged side by side with the conductive plate 31, and the movable plate 32 can move freely along the direction perpendicular to the side wall of the conductive plate 31;

[0037] Memory spring...

Embodiment 2

[0044] like Figure 6-7 As shown, the difference between this embodiment and Embodiment 1 is that the side wall of the movable plate 32 is in sliding and sealed connection with the side wall of the cavity 3, and the two ends of the movable plate 32 are respectively penetrated with a one-way liquid inlet pipe 61 and a The one-way liquid discharge pipe 62, it is worth mentioning that the one-way liquid inlet pipe 61 and the one-way liquid discharge pipe 62 can be realized by a one-way valve, and a circulation channel 52 is provided between the cavity 3 and the cooling chamber 4, and the circulation The passage 52 is in sealing communication with the one-way liquid inlet pipe 61 through the first elastic bellows 611, and the connecting passage 51 is in sealing communication with the one-way liquid discharge pipe 62 through the second elastic bellows 621. It should be noted that the connecting passage 51 is in communication with the cooling cavity The lower part of 4 is connected....

Embodiment 3

[0047] like Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that the handle of the gun body 1 is evenly provided with cooling fins 8 .

[0048] In this embodiment, by providing the heat dissipation fins 8, not only the heat dissipation effect on the insulating liquid can be further improved, but also the anti-skid performance of the charging gun can be improved, and the situation of the charging gun slipping can be reduced.

Abstract

The invention belongs to the field of new energy automobiles, and particularly relates to a new energy vehicle charging gun. The new energy vehicle charging gun comprises a gun body, wherein the frontend of the gun body is fixedly connected with a plug, the gun body is internally provided with a cavity and a cooling cavity which are filled with insulation liquid, and the cavity communicates withthe cooling cavity through a connection channel. The cavity is internally provided with: a conductive plate fixedly connected at the side wall of the cavity, wherein the conductive plate is electrically connected with the plug; a movable plate arranged with the conductive plate side by side; a memory spring, wherein two ends of the memory spring are respectively fixedly connected with insulation blocks, and the two insulation blocks are respectively fixedly connected with the movable plate and the side wall of the conductive plate; and a first conductive barrel fixedly connected with the sidewall of the conductive plate, wherein the first conductive barrel is formed by a conductive ring and an insulation ring. When the charging gun is high in temperature, the automatic outage protection can be achieved to cool the internal portion of the charging gun so as to greatly reduce the accidents due to too high temperature in the charging process.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, in particular to a charging gun for new energy vehicles. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as a power source, which can reduce the consumption of petroleum resources and reduce pollutant emissions. Among them, pure electric vehicles are the most widely promoted. [0003] When charging a new energy vehicle, it is usually necessary to use a charging gun for charging. The existing charging gun does not have a good heat dissipation effect. Due to the large current transmission power, especially in high temperature weather, it is easy to cause the temperature inside the charging gun to be too high, resulting in charging problems. If it cannot be used normally, or even burns out, once an electric fire occurs, the consequences will be disastrous. [0004] Memory alloy, that is, an alloy with shape memory effect, it has a shape at low te...
