DC044B-2.0

This is a DC power socket, also known as a DC power jack. It is typically used in electronic devices as an interface for external DC power input.

Structurally, it generally consists of a metal shell and internal contact springs. The metal shell serves the functions of fixing and shielding, ensuring the socket is securely installed on the device while reducing the impact of electromagnetic interference on the device. The internal contact springs are responsible for making electrical connections with the external DC power plug, introducing power into the device to provide stable DC power to it. 

This type of socket is widely used in various portable electronic devices such as laptops, tablets, routers, set-top boxes, etc., facilitating power supply to the devices through external power adapters. Different devices may adopt DC power sockets of different specifications, such as differences in interface size, shape, pin definition, etc., based on their own design and power requirements.

    Different electronic devices have different design and power requirements, so DC power sockets come in various specifications. The size and shape of the interface are important factors. For example, some small electronic devices may use smaller-sized DC power sockets to match their compact body design, while larger devices may require larger sockets to meet higher power transmission needs. The pin definition of the socket is also a key specification. Different pin arrangements and functions can adapt to different power supply and signal transmission requirements of devices, ensuring the correct and safe operation of the device.

    Core Functions

    EMI/RFI Shielding: Equipped with a 360° fully enclosed shielding layer made of copper alloy or stainless steel, it can effectively absorb radiation interference and ensure the stable operation of the device in complex electromagnetic environments.

    High Current Transmission: It can support a current range of 5A to 30A (depending on the model). The copper alloy contacts are gold-plated or silver-plated to reduce impedance, ensuring efficient power transmission and minimizing energy loss.

    Mechanical Protection: The shell has an IP67/IP68 protection rating, which can effectively resist vibration, dust, and water, ensuring the normal operation of the socket in harsh environments.

    Anti-Misinsertion Design: Adopting a keyway or polarization structure, it can prevent reverse insertion, avoid damage to the device due to incorrect insertion, and improve the safety and reliability of the product.
