Terminal blocks, also known as wire to board connectors, are electrical devices which provide a secure, low contact resistance connection between wires, cables, or other conductors to the PCB. They have a variety of application fields, depending on the specific type. The 1727036 is a mating part which comes with a female terminal, main body and cover.

1727036 Application Field

1727036 terminal blocks are mainly used in electrical and electronic applications. They are also commonly used as grounding terminals, as they are able to resist vibratory loads when properly mounted. This type of terminal block is especially suitable for installations with increased environmental stress, like vibration, shock, or cold temperatures.

It is commonly employed in industrial equipment such as transformers, electrical equipment like power supplies, motors, and in control electronics applications wherever device connection is required. It can be used to build enclosures in all kinds of fields, like automotive, robotics, and telecommunications.

1727036 Working Principle

The 1727036 terminal block assembly consists of a male terminal and a female terminal. The male terminal is inserted into the contact part of the terminal, making an electrical connection. The female terminal is then inserted into the contact part of the male terminal, forming a secure connection. The main body is then snapped into the cover, which prevents the male and female terminals from coming apart.

The electrical connection between the terminals is realized by the electrical forces that exist between the contact surfaces. The electrical forces depend on the contact pressure, contact surface area, and contact material properties. It is important to ensure that both the contact surface area and the contact force are large enough to create a secure electrical connection.

The contact pressure on the terminal is created by screws and nuts, which exert a certain force. This type of terminal block is usually designed with thread pitches that can provide maximum contact pressure, ensuring a secure electrical connection between the terminals.

In order to maintain contact resistance and improve the lifetime of the terminal, it is important to use quality material for the contact points. Quality materials have low magnetic permeability, good thermal conductivity, and excellent corrosion resistance.

Conclusion

The 1727036 terminal block is a useful and versatile part for electrical wiring applications. It is commonly used in industrial equipment, like transformers, motors, and control electronics. It is designed with thread pitches that can provide maximum contact pressure for a secure electrical connection. The correct choice of mate contact materials is essential to ensure good contact resistance and long lifetime.
