The internal structure of the winter thermal socks oem mainly includes the following parts:

1. Layered clothing and pants: winter thermal socks oem usually adopts a layered design. This design allows heating elements to be placed inside the clothing and pants while maintaining external comfort and aesthetics.

2. Wires: Wires are an important part inside the winter thermal socks oem. They are responsible for transmitting electrical energy to the heating elements. Wires are usually placed in the interlayer of clothing or trousers. Two wires run across the upper and lower ends of the interlayer of the clothing or trousers respectively. One end is connected to the input and output of the external rechargeable battery, and the other end is sealed with insulating rubber.

3. Heating wire: The heating wire is the heating element inside the winter thermal socks oem, and they are connected in parallel between two wires. Electric heating wires are usually made of low-voltage resistance wires to ensure safety and heating speed.

4. Rechargeable battery: The rechargeable battery is the energy supply part of the winter thermal socks oem. They provide electrical energy for the heating wire. The voltage range of rechargeable batteries is usually between 3.6V and 24V, and they come with chargers so that users can recycle them.

5. Regulators and switches: Regulators and switches are used to control the heating temperature and working time of the winter thermal socks oem. The regulator can be set to different temperature levels to meet the needs of users in different environments. The switch is used to control the on and off of the winter thermal socks oem.

6. Other components: Depending on different designs, the winter thermal socks oem may also include other components, such as carbon fiber heating films (such as the back heating film in some styles), protective covers, wiring pressure plates, etc. The existence of these components is all for better realizing the functionality and comfort of the winter thermal socks oem.

To sum up, the internal structure of the winter thermal socks oem mainly consists of laminated clothing and pants, wires, heating wires, rechargeable batteries, regulators and switches, etc. These parts work together to achieve the functions of heating, insulation and comfort of winter thermal socks oem. Meanwhile, the design of these parts also takes into account factors such as safety and durability.
