5.5 x 2.1 mm male and female dc power jack socket
May 20, 2023
DC power jack socket is a crucial component that is utilized in a wide array of electronic devices and equipment, in which the power is supplied by DC (direct current) supply. It is a type of electrical connector that enables DC equipment to interconnect with external power sources. These jacks are predominantly used in applications such as tablets, laptops, mobile phones, power banks, etc. They have a cylindrical shape and are known by various names, such as barrel jack, power jack, DC socket, etc.
One of the most popular sizes of DC power jack sockets is the 55x21mm male and female jack. It is a standard size of DC jack that is widely used in various electrical applications. This jack is circular and has a diameter of 5.5 mm and length of 21 mm. The male part of the jack has a center pin that is used for a positive power connection. The female part has a center hole that receives the pin and is used mainly for mounting the jack to the device.
The 55x21mm male and female DC power jack socket is made of high-quality materials such as copper, brass, and plastic. The jack is durable, reliable and easy to install. The plastic material is used for the external insulation of the jack socket. The copper and brass are used for the inner components. Copper is used as it is an excellent conductor of electricity and can provide a stable and reliable connection even with a high voltage power supply. Brass is used for the mechanism of the jack.
The male and female parts of the DC power jack socket are designed to interlock securely, creating a solid and reliable electrical connection. To ensure the jack will not come loose easily, a locking mechanism is built into the female part of the jack. This mechanism holds the male plug firmly in place, ensuring a safe and secure connection.
The 55x21mm male and female DC power jack sockets have an input voltage range of 5V to 36V, meaning that they are compatible with a wide range of electrical appliancations. The maximum current rating of the jack is around 5A, which is sufficient for most devices.
One of the most significant advantages of using a DC power jack socket is that it prevents reverse polarity. This means that the DC power jack socket can only be connected one way, which reduces the risk of damage to the device or equipment that is being powered.
In summary, the 55x21mm male and female DC power jack socket is a standard size of DC jack that is widely utilized in electronic equipment and devices. It is made of high-quality materials, which make it reliable and durable. The jack is easy to install and can handle a voltage range of 5V to 36V and a current of up to 5A. Its locking mechanism ensures a safe and secure connection, while its prevention of reverse polarity is an added advantage. Overall, the 55x21mm male and female DC power jack socket is an essential component for any electronics project.
