What is DC Jack?

DC Jack is a component used in many electronic devices that allows you to connect a stable energy source. Although electronics require direct current (DC), AC current (AC) is a type of electricity supplied and available in wall boards, mainly due to its ability to be supplied at long distances without losing force. Therefore, with most electronics, the AC adapter is connected to the DC connector necessary to supply energy in a usable way. Unlike the AC plugs, which are uniform and regulated on the grounds of Earth countries, DC connectors and plugs that are technically referred to as coaxial power connectors are not generally standardized. Many electronics manufacturers have their own proprietary alternate adapters, also known as Power Bricks , which use unique DC connectors. Currently, Germany and Japan are the only countries that have tried to issue standards for the size of DC Jack. Different alternate adapters and DC connectors can oftenAnd respects, from voltage to physical diameter. DC Jack is designed to accept only one size of the connector. While different sizes can really look similar, it may be potentially dangerous to try and pair inappropriate power supply with the device.

While the most common DC jack connectors are 0.5 mm (5.5 mm) and 0.37 inches (9.5 mm), it is not unusual to meet some that are much longer and wider. Although this is not an absolute rule, larger connectors usually indicate a higher voltage. Sony® is remarkable for the introduction of a system for its device that denotes voltage in this way.

Especially with laptop computers, the DC connector is prone to wear of wear over time. With frequent connections and disconnecting the jack itself, it can begin to release and wear its housing, allowing the connector to slip and disrupt strength. While repairing do-it-youourself can restore tightNot adapting without expensive workforce costs, soldering is required, and for amateurs the risk of greater damage to the device may be considerable.

Less common than DC connectors that pair with AC adapters are styles known as Snap and Lock Connectors . These connectors are standardized, with an outer diameter of 0.394 inches (10 mm) and connecting pins with a diameter of 0.06 inches (1.5 mm). The outer jacket of the Snap and Lock connector is grooved in a way that corresponds to the grooves inside the paired DC connector and offers a durable physical connection. Examples of this design include PS/2 connection used by some computer keyboards and mice.
