The position of terminal screw connection in the electronics industry
Screw-connected terminals have always occupied an important position in the electronics industry, and now they have become an important part of printed circuit boards. Its structure takes into account the characteristics of wiring, such as convenient and reliable screw connection. There are two types of printed circuit board terminals with spring connection: return spring connection and butterfly spring connection. The pull-back spring terminal and screw terminal are compatible with each other, which greatly increases flexibility. Reliable connection, front connection, obvious connection, low maintenance cost, no need to tighten.
The terminal block utilizes the existing RTB connection technology of the terminal rail to add a circuit composed of electronic components to realize the transmission coupling of the photoelectric process. The core of automatic control is that the control unit must be reliably isolated from each sensor and actuator to avoid interference. Optically isolated terminals can perform 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 an interface component between process control peripherals and control, signal and regulator devices, and is suitable for different voltage and power ranges.
The terminal has a large contact area and high contact pressure, allowing horizontal communication at will. It has self-locking, anti-vibration and locking functions. The test jack can be installed without maintenance. The contact points are absolutely airtight and corrosion resistant. Multi-strand wires can be connected directly without crimping the ends. Easy to use, widely used all over the world, with high contact pressure. Optically isolated terminals have the advantages of low signal loss at the control end, high switching frequency, no mechanical contact jitter, no wear switching, high isolation voltage, no fear of vibration, no positional influence, and long service life. Therefore, they are widely used in the field of automatic control.
