The importance of terminal appearance

The terminal blocks play an important role in the appearance of the product and the user's affinity. The power terminal blocks must be convenient for field installation, because they are often installed on the front end of the product panel that is easy to see. In this way, marketers often hope to have a certain say in the appearance of power terminal products. But often encounter this situation: the product designed by the engineer meets all the mechanical and electrical parameter requirements, but has to be changed because it does not meet the sales requirements. If this happens at the end of the design cycle (often when the marketing department sees the prototype for the first time), then a fierce debate is unavoidable and may lead to increased costs and delays in delivery. In many industrial control systems, wiring terminals are often one of the few components that technicians need to pay special attention to. Although its user interface is relatively simple (mainly screws), it is very important for the normal operation of the device.

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 increase. Therefore, the power terminal requires larger screws and a stronger insulating shell. Sometimes small screws are used to save space. This is often the case in very compact terminal products. Some wires are more than 1/4 inch in diameter, so these small screws are difficult to deal with. When technicians and maintenance personnel need to install multiple wires, using large enough screws to simplify the wiring work can greatly save time.

When terminal blocks are used in consumer products (such as high-end stereo products), appearance becomes more and more important. In fact, some designers often specify gold-plating for the terminal devices used in audio equipment. Although this increases the cost and does not significantly improve the performance, the gold-plating does improve the appearance of the product.

Understanding the measurement method of power terminal parameters is a key part of system design. Confirming that the selected power supply terminal meets the temperature range, current and voltage requirements of the power supply device will help ensure the long-term reliability of the system. In addition, if the selected power supply terminal device adopts the wiring technology that can meet the market requirements, and the convenience of user operation is ensured in the design, then the success probability of the final product will be greatly improved.

With the increasing frequency of terminal block products in the field of wiring, more and more users have put forward more requirements on it. For this reason, the structure and wiring method of the terminal have undergone great changes. From the original single structure change, a variety of wiring structures are extended, which are divided into categories, suitable for various wiring environments, and greatly facilitate our use. At the same time, the structure of the connection terminal is becoming more and more humanized, and the connection speed is also greatly improved, which reduces the labor intensity of the workers. At the same time, the reliability of the terminal blocks is getting higher and higher. The use of new production processes and technical equipment, scientific production processes and quality control methods have greatly improved the quality and life of the terminal blocks. With the increasing demand for environmental protection, the environmental protection requirements of the terminal are very necessary. The halogen-free addition of flame retardants, the detoxification of conductor insulators, and the lead-free plating of coatings are all positive responses to this request.
