Is It Better To Use Terminal Or Traditional Wiring?

Good terminal, high efficiency, low resistance, contact surface will not become smaller. The advantage of the terminal is that it makes the connection convenient and simple, safe and stable. However, due to the fierce market competition, the quality of many terminals is not up to the standard, and it is not safe to use them. Therefore, it is recommended to purchase the national standard terminal, and the price difference is not much. It is relatively better to use the terminal. 1. The advantage of the terminal is that the connection is convenient and simple, safe and stable. 2. Terminal is used to achieve electrical connection of a kind of accessories products, industry is divided into the category of connectors. 3. With the increasing degree of industrial automation and industrial control requirements more and more strict and accurate, the use of terminal blocks is gradually increasing. 4. With the development of electronic industry, more and more types of terminals are used. At present, the most widely used in addition to PCB terminals, there are hardware terminals, nut terminals, spring terminals and so on. 5. The terminal is used to facilitate the connection of wires. It is actually a piece of metal enclosed in insulating plastic. There are holes at both ends to insert the wire, and screws are used for fastening or loosening. For example, two wires need to be connected sometimes, and they need to be disconnected again. At this time, the terminals can be used to connect them, and can be disconnected at any time without having to connect them They are welded or twisted together, which is very convenient and fast. And suitable for a large number of wire interconnection, in the power industry has a special terminal block, terminal box, above all are terminal blocks, single-layer, double-layer, current, voltage, common, broken and so on. A certain crimping area is to ensure reliable contact and to ensure enough current. 6. The terminal blocks can be divided into wuk terminal block, European type terminal block series Plug in terminal series, transformer terminal, building wiring terminal, fence type terminal block, spring type terminal block, track type terminal block series, through wall terminal series, photoelectric coupling type terminal block series, 110 terminal, 205 terminal, 250 terminal, 187 terminal, od2.2 ring terminal, 2.5 ring terminal, 3.2 ring terminal, 4.2 ring terminal Terminal, 2 ring terminal, 6.4 ring terminal, 8.4 ring terminal, 11 ring terminal, 13 ring terminal, flag series terminal and sheath series, various ring terminals, tubular terminal, terminal, copper strip and iron strip (2-03, 4-03, 4-04, 6-03, 6-04), etc. 7. It uses the existing rail terminal wuk connection technology, and adds the circuit composed of electronic components to realize the transmission coupling of photoelectric process. 8. The core of automatic control is that the control unit must be reliably separated from each sensor and actuator to avoid interference. The wukg2 optical isolation terminal of Sanmenwan can complete this function well and ensure that the field signal matches the low voltage required by the electronic control device. It can also be used as the interface element between the peripheral equipment of process control and the control, signal and regulator devices, and Suitable for different voltage and power ranges. 9. Optical isolation terminal has the advantages of control signal loss, high switching frequency, no mechanical contact jitter, no wear switching, high insulation voltage, not afraid of vibration, not affected by position and long service life, so it is widely used in the field of automatic control.
