Two-piece wire-to-wire terminals, commonly known as 2PWTP terminals, are a type of terminal block with a two-piece design. These terminal blocks are constructed of two parts: the body, usually made of plastic, and the connection element, which is usually made of metal. The body of the 2PWTP terminal has two wings and a pocket in the center for the connection element. The connection element is inserted through a hole on one side of the body and then crimped into the pocket. This type of terminal connection is particularly useful for wiring harnesses and in applications where a robust and compact electrical connection is needed.

2PWTP terminal blocks can be found in a variety of applications. They are commonly used in industrial and commercial electronics, such as medical, automotive, consumer electronics, and telecommunications. 2PWTP terminals are also used in robotics, automation, mechatronics and instrumentation applications. In addition, they are often used in aviation, aerospace and military markets.

The two-piece wire-to-wire terminal block design has several primary advantages. First, it allows for a convenient, fast and robust connection with a single device and without cutting and soldering wires manually. Second, the pocket in the body for the connection element provides structural rigidity for the connection element. Third, the snap-fit design of the pocket ensures easy assembly of the connection modules. Fourth, it allows for the creation of a minimal contact area in order to reduce electrical resistance and ensure efficient transfer of electrical current between wires. Fifth, the two-piece design provides protection against accidental contact of two adjacent connection elements.

The working principle of 2PWTP terminals is based on the principle of contact resistance. A small electrical current is passed through the contact area, creating an electrostatic field. This field causes the two pieces to become magnetically attracted, increasing the contact area and creating a resistive connection. This connection can then be used to transmit electricity between two wires. Since the connection is made through the contact resistance, it is important to ensure the contact area is clean and free of contaminants in order to reduce the contact resistance.

Overall, the two-piece wire-to-wire terminal block is a reliable and economical way to connect wires in any application. It offers a robust connection that is both compact and easy to assemble. The two-piece design also provides protection against accidental contact and allows for a minimal contact area with reduced contact resistance. This type of terminal block is particularly useful for wiring harnesses in industrial, commercial, robotics, mechatronics and instrumentation applications.
