A deans connector is a type of electrical connector used in a variety of applications, including radio-controlled model aircraft. It is popular among hobbyists as it is relatively easy to use and provides a secure connection with minimal resistance. The deans connector is also known as the T-connector or Ultra Plug due to its unique shape that resembles the letter 'T'. This connector features two male pins and one female contact which are held together by a plastic shell. The pins are soldered to the wires, and the shell is then placed over the pins for extra protection. The main advantage of this type of connector is its low resistance, which helps to decrease the amount of power lost in the connection. Additionally, its secure design prevents accidental contact with other components and helps maintain a reliable connection. Deans connectors can be used with a variety of different types of wire, including silicone wire, flexible wire, and stranded wire. With the right tools and supplies, anyone can easily install and use this type of connector.
