Problems solved by technology
The existing charging piles are all connected to the charging gun through cables. During the charging process, the cables are inaccessible and heat will be generated, which will reduce the service life of the cables and the charging efficiency. Therefore, the application of liquid-cooled cables is born. A layer of liquid cooling layer is added between the wire core and the shielding layer of the liquid cooling cable, and the liquid flow in the liquid cooling layer cools the cable, which solves the cooling temperature; however, how to solve the safety hazard of liquid leakage inside the charging gun cable has become a work There is a difficult problem, the liquid inside the charging gun line leaks during work, which will cause potential safety hazards

Embodiment Construction
[0014] Such as figure 1 As shown, this embodiment provides a device for preventing the liquid from overflowing the charging gun liquid-cooled cable. A layer of liquid-cooled layer 30 is arranged between the shielding layer 20 and the core layer 10 of the liquid-cooled cable. The layer 30 is filled with cooling liquid. When the cable is processed, a plurality of "I"-shaped supports 31 are processed on the outer surface of the core layer 10, and then the shielding layer 20 is processed on the supports 31, and finally poured into Coolant.
[0015] In this embodiment, at least one sensor 40 for detecting liquid leakage is arranged in the liquid cooling layer 30, and a waterproof layer is arranged on the outside of the sensor 40, and the number of sensors 40 depends on the number of liquid cooling cables. Determined by the length and wire diameter, the longer the cable, the more the number of sensors 40, the sensors 40 are installed on the support 31 of the liquid cooling layer 30...

The invention discloses a device for preventing liquid of a liquid cooling cable of a charging gun from overflowing, a liquid cooling layer is arranged between a shielding layer and a wire core layer of the liquid cooling cable, and at least one sensor for detecting whether the liquid overflows or not is arranged in the liquid cooling layer; and waterproof layers are arranged on the outer sides of the sensors, and the multiple sensors are connected in series. The sensor with the waterproof layer is installed on the liquid cooling layer, the pressure, the pressure intensity or the flow speed of the liquid cooling layer is detected through the sensor, whether the liquid cooling layer leaks or not is detected, the structure is simple, implementation is easy, and popularization is convenient.
Description
technical field [0001] The invention relates to the field of cables for charging guns, in particular to a device for preventing liquid from overflowing the liquid-cooled cables of charging guns. Background technique [0002] With the popularity of new energy vehicles, related configurations also need to be improved, such as charging piles. The existing charging piles are all connected to the charging gun through cables. During the charging process, the cables are inaccessible and heat will be generated, which will reduce the service life of the cables and the charging efficiency. Therefore, the application of liquid-cooled cables is born. A layer of liquid cooling layer is added between the wire core and the shielding layer of the liquid cooling cable, and the liquid flow in the liquid cooling layer cools the cable, which solves the cooling temperature; however, how to solve the safety hazard of liquid leakage inside the charging gun cable has become a work There is a probl...
