Description

Technical Field

[0001] This utility model belongs to the technical field of electrical connection connectors, specifically relating to an electric heating antifreeze connector. Background Technology

[0002] Traditionally, electricity is drawn from the car's cigarette lighter socket. However, since the power cord of the traditional cigarette lighter socket has no heating function, the transmission function of the connecting wire is affected when the temperature is extremely low. Therefore, it is very important to obtain a connector that can achieve electric heating. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, this utility model provides an electric heating antifreeze connector, comprising: The connector body, the connector body and the electrical connection wire threadedly connected to the connector body; The connector body includes an insulating substrate, a ceramic substrate is fixed to the first end of the insulating substrate, and a first conductive spring and a second conductive spring are respectively provided on both sides of the ceramic substrate. The first conductive spring and the second conductive spring at least partially protrude from one side of the ceramic substrate and partially retract after being pressed. The second end of the insulating substrate is provided with a threaded groove. One end of the first conductive spring extends from the circular side of the threaded groove to form a first elastic contact portion, and one end of the second conductive spring extends from the center of the threaded groove to form a second elastic contact portion. The electrical connection wire includes a central conductive wire and a sheathing layer that wraps around the central conductive wire. A heating wire is threaded into the sheathing layer. A conductive ring that is electrically fixed to one end of the heating wire is fixed on the annular surface of one end of the sheathing layer. When the electrical connection wire is threadedly installed, the first elastic contact part abuts against the conductive ring to stably supply power to the heating wire; the second elastic contact part abuts against the central conductive wire.

[0004] The other end of the electrically conductive connection is electrically connected to a USB connector or a Type-C connector, adapting to multiple functions.

[0005] The outer ring is formed on the outer periphery of the second end of the insulating substrate, and the outer ring is located on the outer periphery of the ceramic substrate and is spaced apart from the ceramic substrate.

[0006] The outer ring is made of insulating material, and several ring-shaped protrusions are fixed on the inner wall of the outer ring to insulating silicone to facilitate positioning.

[0007] The inner wall of the outer end of the outer ring is provided with a guide slope, and the solution is installed into the insertion hole of the cigarette lighter in the car.

[0008] This invention can also be augmented with an existing temperature control device, including a temperature sensor that can be installed in the wrapping layer on one side of the heating wire. The wrapping layer is made of insulating material. A housing can be fixed outside the wrapping layer, and a circuit board can be installed inside the housing. A switch tube can be electrically connected between the heating wire and the conductive ring. A controller is electrically connected to the circuit board. The input of the controller is electrically connected to the temperature sensor, and the output is connected to the switch tube. The switching tube can be adjusted to turn on and off based on the information from the temperature sensor.

[0009] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure, conducts electricity through the cigarette lighter part of the car, and can heat the electrical connection wires, making it suitable for low-temperature environments such as Northeast China, Antarctica, and the Arctic and Antarctic. It can draw power from inside the car and does not require carrying a separate diesel generator.

[0010] Electrical connectors can be replaced and disassembled. Compared to traditional integrated electrical connectors, if they break at a bend, they can be replaced. This is cheaper than replacing the whole thing, and they can be disassembled when not in use. Furthermore, different electrical connectors with different conductivity can be used to meet different needs. Attached Figure Description
