Terminals play an important role in the appearance of the product and the affinity of the user, and the power terminals must be easily installed on site, as they are often installed at the front of the easy-to-see product panel. In this way, marketers often want to have a certain voice on the appearance of the power supply terminal products. But often encounter the situation: engineers designed products meet all the mechanical and electrical parameters, but did not meet the sales requirements and had to change. If this happens at the end of the design cycle (often the first time the marketing department sees the prototype), then a heated debate is difficult to avoid and can lead to increased costs and delays in delivery. In many industrial control systems, the terminals are often one of the few components that the technician needs to pay special attention to. Although its user interface is relatively simple (mainly screws), but for the normal operation of the equipment is very important.
As the current increases, the wires become thicker and the torque required to fasten these thick wires to the high current terminals also needs to be increased. As a result, the power terminals require larger screws and a stronger insulation housing. Sometimes with small screws to save space. This is often the case in very compact terminal products. Some wires have a diameter of more than 1/4 inch, so these small screws are difficult to deal with. When technicians and maintenance personnel need to install multiple lines, the use of large enough screws to simplify the connection work can save a lot of time.
When the terminal is used for consumption (such as high-end stereo products) products, the appearance becomes increasingly important. In fact, some designers often specify that the terminal devices used for audio devices are gold-plated, which increases the cost and does not significantly improve performance, but gold plating does improve the appearance of the product.
Understanding the measurement method of the power terminal parameters is a key part of the system design. Make sure that the selected power supply terminals meet the temperature range of the power supply. Current and voltage requirements help ensure the long term reliability of the system. In addition, if the choice of power supply terminal devices to meet the market requirements of the wiring technology, and in the design to ensure the convenience of user operation, it will greatly improve the success rate of the final product probability.
With the use of terminal blocks in the field of wiring more and more frequently more and more users to put forward more requirements for this terminal structure and wiring methods have undergone great changes. From the initial single structural changes extend a variety of wiring structure, categorized, suitable for a variety of wiring environment, greatly facilitate our use. At the same time, the structure of the terminal is more and more humane, the wiring speed is also greatly improved, reducing the labor intensity of the workers. At the same time, the reliability of the terminal is also getting higher and higher, the new production technology and technical equipment put into use, the scientific production process and quality control methods greatly improve the quality of the terminal and life. With the increasing voice of environmental protection, the environmental requirements of the terminal is very necessary. Halogen-free addition of flame retardant, non-toxic conductor insulator, lead-free coating, etc. are in response to this requirement and make a positive response.
At present, although our terminal has experienced more than 20 years, has made considerable development, but still did not go out of the big and not strong vicious circle, and world-class enterprises are still a big gap. There are many problems such as low concentration of industry, large number of enterprises and small scale, scale economy is not enough, lack of independent innovation capacity and product structure contradiction and so on. Although there are these problems, but China's cable industry is facing a new take-off opportunity, that is, in the development of rapid improvement of their core competitiveness of the opportunity.
