Screw connection terminals have always occupied an important position in the electronic industry, and now have become an important part of the printed circuit board. Convenience of wiring and solid threaded connection are considered in structure. Spring connection terminals and printed circuit board terminals with spring connection mode are divided into full spring connection and butterfly spring connection. The spring terminals and screw terminals are compatible with each other, and the flexibility is greatly improved. Reliable connection, comprehensive connection, display connection, low maintenance, no need to advance.

The existing rail type terminal RTB connection technology is used for the connection terminal, and the circuit composed of electronic components is added to realize the transmission coupling of the photoelectric process. The core of automatic control is that the control device must be reliably isolated from each sensor and actuator to prevent interference. The air-jet RPC optical bulkhead terminal performs this function well and ensures that the field signal matches the low voltage required by the electronic control unit. In addition, peripheral equipment and control of process control can also be carried out.
The terminal has large contact surface and large contact pressure, and can be connected horizontally at will. It has the functions of automatic locking, earthquake resistance and broadcasting. The test jack can be installed without maintenance. The contact points are absolutely sealed and corrosion resistant. Multiple strands can be connected directly without pressing the end. It is easy to use, and the contact pressure widely used all over the world is very high. Optical isolation terminal has the advantages of signal loss at control terminal, high switching frequency, no mechanical contact jitter, no wear switching, high insulation voltage, vibration prevention, no location impact, and extended life, and has been widely used in the field of automatic control
