62040-2 Connectors, Interconnects

The 62040-2 Standard specifies safety requirements for magnetic wire connectors used in terminals that are used to terminate conductors in electronic equipment, including motor-control and propulsion systems. The scope of Standard 62040-2 specifically spells out what kind of equipment is covered and the scope of the standard limits its application to the use of terminals to terminate conductors in electronic equipment used for specific applications. The Standard applies to three categories of magnetic wire connectors: terminal block connectors, ring terminals, and butt splices.

Terminal blocks are used in a wide range of applications where solid or stranded wires need to connect. As the name suggests, this type of terminal block is designed to provide a reliable, secure connection between two conductors. The main feature of a terminal block is that it is an electrical connection device which contains insulation to help protect the wires from the elements. The terminal block is typically composed of two pieces of material; a ground plate and a hot plate. The two conductors are inserted into either side of the terminal block securely and connected via the combined plates. The terminal block is designed to ensure the two conductors are electrically insulated and do not short out.

Ring terminals are used to create strong electrical connections between two wires. This type of terminal block consists of a metal plate with a U-shaped slot in the middle, which holds two wires. The terminal block has two terminals that allow the wires to pass through the U-shaped slot. The metal plate then presses down onto the two wires to provide a secure and reliable electrical connection. Some ring terminals also feature additional soldering points to ensure a better connection. Ring terminals come in different sizes and materials, and are suitable for connecting both solid and stranded wires.

Butt splices are used to create permanent connections between two wires. This type of terminal block consists of two pieces of metal that are firmly held together in a U-shape. The two pieces of metal are compressed together over the two conductors, providing a secure and reliable electrical connection. Some butt splice connectors come with additional soldering points to provide a secure connection.

The general working principle of these three types of magnetic wire connectors is the same. The metal plates create a physical and electrical connection between the two conductors, while the insulation material around the plates helps to protect the conductors from the elements. These connectors provide reliable, secure connections that can handle high power transmission and ensure the safety of the electrical system.

Standard 62040-2 is essential for the safe usage of magnetic wire connectors in terminals. It outlines safety requirements for the terminals used to terminate conductors in electronic equipment, as well as for the use of the connectors used to make these connections. The Standard ensures that these connectors are fit for purpose, have a high level of safety, are durable and are able to perform in the most demanding of applications.
