Description

Technical Field

[0001] This utility model belongs to the field of new energy vehicle technology, specifically relating to a non-detachable plug for power supply in new energy vehicles. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source and integrate advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles and new technologies and structures. Among existing technologies, pure electric vehicles are the most technologically advanced. Pure electric vehicles use a single battery as their energy storage power source and do not emit pollutants. However, charging requires a power plug. Current plugs are not one-piece injection molded, making them non-detachable and unable to prevent leakage; they lack a structure for detecting the temperature of the power converter, making it impossible to prevent overheating; they cannot detect the internal temperature of the plug to prevent overload; and the safety of powering the vehicle is not yet high enough.

[0023] like Figure 1As shown, this utility model discloses a non-detachable plug for powering new energy vehicles. The plug connects to a socket via a power converter and includes a bracket 10 and a frame 2 connected to the bracket. The bracket 10 is connected to a live wire 8, a neutral wire 9, and a ground wire 4. The upper part of the frame 2 is provided with a temperature detection contact piece 1 for contacting the power converter to conduct the temperature of the power converter. A temperature control signal connection line 3 is connected to the temperature detection contact piece 1. The lower part of the frame 2 is provided with a thermistor 6 for detecting the internal temperature of the plug. A thermistor connection line 7 is connected to the thermistor 6 for transmitting the detected signal.

[0024] In this embodiment, the thermistor 6 is connected to the grounding wire 4 through the thermistor grounding wire 5 to ensure electrical safety.

[0025] In this embodiment, the bracket 10 is a 16A national standard bracket, which is a standard part.

[0026] In this embodiment, the frame 2 is a PP frame. The PP frame is resistant to high temperature and flame retardant, and is used to fix internal parts, thereby improving the safety of charging new energy vehicles.

[0027] In this embodiment, the temperature sensing contact piece 1 is made of brass and embedded in the upper part of the frame 2. The temperature sensing contact piece 1 serves as the temperature sensing contact point for the power converter. The temperature is transmitted to the temperature control sensor via the temperature control signal connection line 3 to prevent the power converter from overheating and ensure its normal operation. The brass construction of the temperature sensing contact piece 1, embedded in the upper part of the frame 2, provides a large contact area with the power converter, making it convenient and reliable.

[0028] In this embodiment, a thermistor mounting slot is provided at the lower part of the frame 2, and the thermistor 6 is disposed in the thermistor mounting slot. The thermistor 6 is used to detect the internal temperature of the plug, preventing overheating of the plug due to overload or other reasons, thus ensuring electrical safety.

[0030] This utility model is used in conjunction with a power converter when powering new energy vehicles. After plugging the power converter into the socket, the plug is then plugged into the power converter. The temperature of the power converter is fed back through the connection of the temperature sensing contact 1 to prevent the power converter from overheating and ensure its normal operation. The internal temperature of the plug is detected by the thermistor 6 to prevent overheating caused by overload, thus ensuring electrical safety.
