Several factors that distinguish the quality of terminal block
At present, the continuous improvement of the circuit board technology so that the terminal can be installed on the terminal can carry a lot of current, has exceeded the limits of 110A, far more than the level of the previous product, the quality of the terminal block is directly related to the fundamental interests of connector manufacturers. As far as we know, the impact of terminal quality factors are the main factors of the terminal design, terminal selection and terminal processing technology three aspects, the terminal customers in the choice must pay attention to carefully distinguish.
Wiring terminal products, like a piece of art work looks for the cool feeling; many terminal companies consider it in the appearance of the product and the user's affinity plays an important role. Terminal blocks must be convenient for installation, as they are often installed on the front end of the easy to see product panel, so that marketers often wish to have a say in the appearance of terminal products.
Secondly, the selection of large current terminal is better than the material of the material of the insulation is used for the engineering plastics, the material of the conductive material must not be used for the iron; the plastic insulation material and the conductive parts of the terminal block are directly related to the terminal's quality. Any failure of a terminal block will result in the failure of the whole system.
The hub of the terminal is the processing of the terminal, the thread is not good, the torque is not up to standard, then lost the role of the connecting wire. The thread is said to be the wiring terminal of the meter, so as to connect with the site, such as the industrial field of some two wire system of the transmitter, the common use of wire cable fixed connector.
Modern terminal design, material and processing technology are three key factors affecting the quality of the terminal, and accurate processing of good terminal design, material choice and processing is the wiring terminal production manufacturers of the decisive prerequisite.
In electronic equipment, the application of high current terminal has become a trend, and the power supply terminal device itself is gradually increasing, and can carry more power. With the size of the terminal block, they are more important in the function of the equipment, and also play an increasingly important role in ensuring the product characteristics. Engineers must also consider another factor that is often overlooked, that is, market marketing considerations. In general, the terminal is visible to the user, so the marketing department often want to be able to match the color and style of the whole system.
The continuous improvement of the circuit board technology so that the plug connection terminal can be installed on the board to enhance the load of a lot, the current has exceeded the limits of 110A, far more than the level of the previous product, which makes the design process in the end to use what kind of power supply terminal can meet the requirements of this problem becomes more complicated. In addition, the method of measuring performance parameters in different regions is also different, and even the same kind of product has a considerable difference in the nominal parameters. Therefore, it is important to understand these differences in order to obtain long-term reliability and guarantee the low cost.
