do you know different terminal block how to connect wire ?

14 kinds of terminal blocks that you will definitely encounter in automation. 

The first kind of rail-type terminal block that you definitely haven't seen before is pressed and loosened by screws. 

This is a perfect match with an electric screwdriver. In addition, let me tell you a trick.

 If you connect this kind of terminal shape, you have to insert this into the left side of the screw, and the more you screw it, the tighter it will be. 

The second type is the rail-type shrapnel terminal, which needs to be inserted into this slot with a flat screwdriver, 

and the internal mechanism is pryed by the screwdriver, so that the shrapnel of this wiring port bounces up. 

Then the wire is inserted and loosened, and the wire is tightly fixed. It should be noted that this flat screwdriver should not be too wide, otherwise it won't be inserted in.

 You should have many broken ones. This kind of terminal is really convenient to screw. The third type is the rail-type plug-in terminal.

 The principle of this is similar to the shrapnel terminal, but it is more convenient for wiring. 

Just press this button with a tool and you can plug in the wire. I really like this.

 The fourth type is the guide rail screw terminal. By twisting the screw, the lower patch is squeezed upward and the wire is suddenly pressed.

 It feels that it is not very different from the traditional wiring method. Just made a cosmetic upgrade.

 The fifth is the breakout terminal. When it's time to break the line. This kind of terminal is very useful, 

the sixth kind is the skin-free terminal, this kind of terminal does not need to cut the wire with wire pliers, as long as the terminal is stuck on the patch inside the wire, 

it will cut the wire skin in the process of you pressing, contact the cable of the inner core, 

at this time, press the wire well and insert it into the end of the terminal, if you just don't have tools in your hand in the process of wiring, it is the most convenient to use this kind of terminal.
