Appearance factors considered in selection of power terminal board

Although the name "power terminal board" doesn't sound beautiful, many companies think it plays an important role in product appearance and user affinity. Power terminal board professional with switching power supply and dual power supply above!

Power supply terminal boards need to be easy to install on site, because they are often installed on the front of the product panel which is easy to see. In this way, marketers often want to have a certain say in the appearance of power supply terminal board products. But it is often encountered that the products designed by engineers meet all the requirements of mechanical and electrical parameters, but have to be changed because they do not meet the sales requirements. If this happens later in the design cycle, then a heated debate is inevitable, which may lead to increased costs and delivery delays.

In many industrial control systems, power terminal board is often one of the few components that technicians need to pay special attention to. Although its user interface is relatively simple (mainly screw), it is very important for the normal operation of the device.

In general, as the current increases, the wires become thicker, and the torque required to fasten these thick wires to the power terminal board also needs to increase. As a result, the power terminals require larger screws and a stronger insulating enclosure. Sometimes small screws are used to save space. This is often the case in very compact power terminal board products. Some wires are more than 1 / 4 inch in diameter, so these small screws are hard to handle. When technicians and maintainers need to install multiple lines, it can save a lot of time to use large enough screws to simplify the connection work. This is also the reason why it is so important for engineers to listen to the opinions of the marketing department as early as possible in the design process. If the power terminal board needs to be polished or colored properly, it is much easier to propose these parameters as original product requirements than to adjust them at the end of the development cycle.

When the power terminal board is used in consumer products (such as high-end stereo products), the appearance becomes more and more important. In fact, some designers often specify gold-plated power terminal board devices for audio equipment, which increases the cost and does not significantly improve the performance, but gold-plated products do improve the appearance.
