Terminal blocks labeling method

 Same element group, before the number preceded by the letter, if not necessary to distinguish phase, available digital-5N, -2.5, -16 mark.
 Same set of components. With a specific electrical wire terminals connected to a sign. The pressing means is the terminal blocks between the conductor and the conductive body of the pressure generated only generate sufficient pressure to ensure a low contact resistance, a good connection is formed, the reliability of the pressing machine is connected directly to the wire impact good or bad. Speaking of screw-type plug in terminal block screws, studs and are important components platen clamping mechanism; screwless terminals for speaking, spring or spring card is an integral part of the compactor. No screw-type spring terminal block ,clamping mechanism is mainly spring, so crucial to the selection of the spring, it is necessary to ensure that there is sufficient contact pressure to ensure that not too much damage to the wire,PCB Spring Terminal Block is more reliable screwless terminals. When the line, you can block or suppress the spring by pushing a screwdriver, into the line, release the spring, the spring tension back pressed firmly to the wire, resulting in sufficient contact pressure, and then strangled with a spring wire cutting edge, so it does not pull out loose or man-made.
 Each terminal in the middle of said single element in a natural number incremented sequence number.
