Here are some application cases of DC sockets with wire harnesses:
In the Consumer Electronics Field:
- Laptops: For example, in the Dell Inspiron 17 series laptops, the DC socket with wire harness connects the external power adapter to the internal circuit of the laptop, providing a stable DC power supply to ensure the normal operation of the laptop.
- Tablets: Tablets such as Apple iPad and Huawei MatePad connect to the charger through the DC socket with wire harness to achieve fast charging, meeting the daily usage needs of users.
- Portable Speakers: Take the Sony SRS-XB13 portable speaker as an example. The DC socket with wire harness is used to connect to the power source, enabling the speaker to continuously play music in outdoor and other scenarios.

In the Automotive Electronics Field:
- In-vehicle Navigation Systems: Taking the in-vehicle navigation of the Tesla Model 3 as an example, the DC socket with wire harness supplies power to it, ensuring that the navigation system works stably during the vehicle's driving and providing accurate navigation information for the driver.
- Driving Recorders: Products like the 360 driving recorder connect to the vehicle's power source through the DC socket with wire harness and automatically start recording when the vehicle starts, documenting various situations during the driving process.
- In-vehicle Refrigerators: Some high-end vehicles are equipped with in-vehicle refrigerators, such as the in-vehicle refrigerator of the Mercedes-Benz S-Class. It connects to the vehicle's power source through the DC socket with wire harness to maintain a low-temperature environment inside the refrigerator, facilitating passengers to store food and beverages.

In the Industrial Equipment Field:
- Automated Production Line Equipment: In the automated production lines of automobile manufacturing factories, various devices such as robots and robotic arms connect to the power source through the DC socket with wire harness to achieve precise motion control and long-term stable operation.
- Industrial Control Computers: Industrial control computers of brands like Siemens and Advantech usually use the DC socket with wire harness for power supply to adapt to the complex electromagnetic interference and power fluctuations in the industrial environment.
- Instruments and Meters: For example, Fluke's electronic testing instruments connect to the power source through the DC socket with wire harness to ensure that the instruments can provide stable power during the measurement process and guarantee the accuracy of the measurement results.
In the Smart Home Field:
- Smart Cameras: Smart cameras such as Xiaomi Smart Camera and Dahua LeChange Smart Camera connect to the power source through the DC socket with wire harness to achieve 24-hour uninterrupted monitoring, and users can remotely view the situation at home through their mobile phones.
- Smart Door Locks: Smart door locks of brands like Loock and Kaadas are powered by the DC socket with wire harness, ensuring the normal operation of functions such as fingerprint recognition and password unlocking of the door lock and ensuring home security.
- Smart Lighting Fixtures: Products like the Philips Hue smart bulb connect to the power source through the DC socket with wire harness. Users can control parameters such as the on/off, brightness, and color of the lighting fixture through a mobile phone APP to achieve intelligent lighting.
