The world's first modular terminal block, invented by Phoenix Contact in 1928, was the prototype of modern terminals. As the degree of industrial automation becomes higher and the requirements for industrial control become stricter and more precise, the amount of wiring terminals is gradually increasing. Due to the continuous development of the electronics industry, terminal blocks are being used more and more widely in more industries and more and more types.
Here is the content list:
●What are the characteristics of through-wall terminal blocks?
●What are the characteristics of fuse terminal blocks?
●What are the characteristics of the test terminal blocks?
The wall-through type adopts screw connection wire technology, the insulating material is PA66 (flame retardant grade: UL94, V-0), and the connector uses high-quality and highly conductive metal materials. H-type through-wall terminal blocks can be installed side by side on panels with a thickness of 1mm to 10mm, and can automatically compensate and adjust the distance of the panel thickness to form terminals with any number of poles. If you want to increase the air gap and creepage distance, you can use partitions to complete. The through-wall wiring terminal can be firmly installed in the rectangular reserved hole on the panel, without any tools, and the installation is extremely convenient. H-type through-wall terminal blocks are widely used in some occasions that require through-wall solutions: power supplies, filters, electrical control cabinets, and other electronic equipment. This type of terminal has good insulation performance, high protection level, and is very convenient to use. It can save users many unnecessary wiring steps, and they can work directly after external wiring. The insulating material of the UK series terminal blocks is modified nylon (PA66), which can be connected to electrical connection products with a 4mm2 conductor voltage of 800V and a current of 41A.
The safety terminal block adopts insulating material-modified nylon (PA66), which has good electrical and mechanical properties. The screws of the terminal block are made of high-strength copper alloy, the conductor part is made of electrolytic copper, and the wireframe is made of alloy copper that resists stress crack corrosion. The surface of these metals is also tinned or nickel-plated for protection. The all-copper terminal block can avoid the battery effect of steel metal parts and copper wires in a humid environment. There is a connection hole in the middle of the terminal block, which can not only be connected in the middle but also can be connected with a side plug connector; the terminal block can be connected to electrical products with a conductor voltage of 800V and a current of 41A.
The sliding metal part of the test terminal block functioning as a switch can withstand the maximum working current through the terminal block crimping frame. When switching, use a screwdriver to loosen the screw and move the slider. The switch position is clear at a glance; there are test sockets at both ends, which are equipped with the corresponding test terminal blocks that can be connected and tested without interrupting the operation when measuring the current. It can be connected to a circuit with a voltage of 660V and a current of 57A.
