Terminal Blocks - Barrier Blocks

YK4140203000G is a terminal block that falls under the category of barrier blocks. Barrier blocks, as their name implies, provide physical barriers between electrical contacts in order to protect electrical conductors and circuits from damage due to accidental short circuits. YK4140203000G has a number of features that make it an especially useful and reliable terminal block in various applications.

Application Field

YK4140203000G barrier blocks are mainly used in power electronics, power distribution networks, and industrial applications. It can be used in applications that require high rates of current transfer without having to worry about short circuits due to contact bouncing or bulging. Moreover, YK4140203000G has excellent thermal properties, making it suitable for high current applications in almost any environment.

YK4140203000G is also ideal for applications where high mechanical stability and electrical protection is a must. It is a suitable solution for applications with high frequency switching rates, such as in locomotives, off-road vehicles, and wind turbines.

Working Principle

YK4140203000G is designed with features that help it provide reliable, stable, and secure connection between electrical contacts. The hood of the terminal block is designed as a barrier to protect against dust, dirt, and liquids. The hood helps minimize contact bouncing and potential short circuits.

Under the hood, there is a plastic finger which acts as the electrical contact. The finger is insulated from the hood with an insulation liner. The finger has a conductive part which consists of a metal core surrounded by a contact chamber. The contact chamber forms an arc-like feature that increases the current carrying capacity and reduces the electrical resistance.

The contacts of YK4140203000G are held in place by pressure springs. The pressure springs keep the contacts tightly together, so that there is minimal electrical resistance. This ensures a stable electrical connection.

YK4140203000G is designed with an insulation sleeve, which further increases the safety of the terminal block in high voltage applications. The insulation sleeve helps prevent short circuits due to contact bouncing, vibration, and moisture.

YK4140203000G is also designed with a thermal silicone pad, which helps dissipate heat generated by the electrical current. This helps maintain the stability of the contact point, even when transferring high levels of current.

In summary, YK4140203000G is a versatile terminal block that can be used in many different applications. Its features of providing reliable electrical connections, insulation, and thermal stability make it an ideal choice for a wide range of industrial, automotive, and power applications.
