All companies involved in the production of components for the energy sector are faced with ever-increasing demands on their products. Nowadays, it is not enough just to make a terminal or switch, now the final product must meet many requirements and combine the following properties: be energy efficient, be maximum compact and energy intensive, and also include the universality property, i.e. operate not only with strong currents, but also with control signals and information.
Thanks to the ongoing changes in the technological process for the production of electrical components, we have achieved a marked improvement in the properties and characteristics of the terminals for printed circuit boards. Using the new development of our engineers – terminal LXXX 15.00 for printed circuit boards you will eliminate the need to use various complex technical solutions based on the use of buses for switching currents up to 150 A. The terminal LXXX 15.00 is easy to install, use and provides reliable and safe signal switching.
The higher the current, the stronger the influence of various factors
In the technology of electrical connections on printed circuit boards, there are 2 most important parameters that determine the terminal’s resistance to load: these are surface quality and soldering quality. The experience of Weidmueller in the field of electrical connections gives us the right to conclude that the higher the load (electric current), the greater the influence of various factors on the temperature increase in the device. In addition to the active components of the electrical circuit, on which heat is generated, other components that influence the temperature increase in the device can be distinguished: these are the board size, the presence of jumpers and the length of the conductors, the design of the pins and the material and the quality of the solder and terminal.
Temperature charts
Using temperature charts it is very convenient to analyze the influence of various factors on the temperature distribution in the device. Using them you can determine the quality and material of the solder and other parameters. For example, in the figure on the left, we can notice a rather low temperature on the surface – below and above. This indicates a high-quality soldering.
The key factors for the success of the new LXXX 15.00 terminal model are the reduced size and increased permitted load and current flow. Also in this model all our latest developments in the field of creating electrical connections are combined.
