From the perspective of the development history of modern electrical technology, the original terminal is a metal sheet, wrapped in insulating plastic, used to connect the accessories of the wire.
After continuous technological innovation, terminal blocks are widely used in all aspects of industry, and even industry application standards are also stipulated in accordance with the technical system.
In the past, when there was no terminal, people could only twist the wires repeatedly. When they needed to connect or disconnect, they had to patiently connect and disconnect the wires. This is really a very complicated thing. What's more, people also need to solder the wires, which is also a technical activity.
Although the connection terminals are used in our daily life, but to choose suitable terminals to meet our daily needs. There are many brands of terminal blocks. Under normal circumstances, our most common ones are PHOENIX, WAGO, SUPU, etc.
Under different classifications, the total number of wiring terminals has even reached tens of thousands: plug-in type, MCS, spring type, screw wiring, etc.
Encountered crimping and thread self-locking design, that is the rail-type terminal, it can be used with a variety of accessories, such as shorting plates, baffles and so on.
On the construction site, the most commonly used are through-wall terminal blocks, which have better insulation performance. After the connection, they can be directly worked outdoors, so some wiring steps can be reduced or directly omitted, in a constantly changing work environment , It is more important to choose the appropriate terminal.
The indoor wiring terminal is used for convenient and quick wiring. This terminal is also widely used in home and office lighting, electrical connection of low-power household appliances and interior decoration.
Of course, any product has a service life problem, and the terminal is no exception. There will be some obvious failures, such as contact, poor fixation, and loss of insulation.
Therefore, it is also necessary to learn to solve these problems in time. We can adopt short-break detection, single-hole separation detection, continuity detection, etc. At the same time, we also need to perform other technical tests to prevent other potential problems.
