The terminal block is a kind of accessory product used to realize electrical connection, which is divided into the category of connector in industry. ATO offers high current terminal block, pluggable screw terminal block, barrier terminal block and DIN rail terminal block four types for selection, wide range rated current from 8A to 400A are available. Terminal block connectors have factory price, good performance and fast response. Electrical terminal blocks are widely used used for electric power industry.
The terminal is a bridge of communication between the blocked or isolated circuits in the circuit, so that the current flows and the circuit achieves the predetermined function. Looking down the path of current flow, you will always find one or more terminals. The form and structure of this kind of product are ever-changing, with different application objects, frequency, power, application environment, etc., there are various forms of connectors. But no matter what kind of terminal block, it is necessary to ensure that the current flows smoothly, continuously and reliably.
Terminals can be divided into:
It consists of two parts plug-in connection, one part presses the wire, and then plugs into the other part, which is soldered to the PCB board. The mechanical principle of the bottom connection and the anti-vibration design ensure the long-term airtight connection of the product and the reliability of the finished product. Mounting ears can be added at both ends of the socket. The mounting ears can protect the tabs to a large extent and prevent the tabs from being poorly arranged. At the same time, this socket design can ensure that the socket can be inserted into the mother correctly. Receptacles can also have assembly snaps and locking snaps. The assembly buckle can be used to more firmly fix to the PCB board, and the locking buckle can lock the mother body and the socket after the installation is completed. A variety of socket designs can be matched with different mother insertion methods, such as: horizontal, vertical or inclined to the printed circuit board, etc., and different methods can be selected according to customer requirements. Available in both metric and standard wire gauges, it is the best-selling terminal type on the market today.
It can realize safe, reliable and effective connection, especially in the environment of high current and high voltage.
Spring terminal is a new type of terminal using spring device, which has been widely used in the world's electrical and electronic engineering industries: lighting, elevator control, instrumentation, power, chemistry and automotive power.
The use of crimping wire and unique thread self-locking design makes the wiring connection reliable and safe. The design of this series of terminal blocks is beautiful and elegant, and can be equipped with a variety of accessories, such as short-circuit strips, identification strips, baffles, etc.
Using screw connection wire technology, the insulating material is PA66 (flame retardant grade: UL94, V-0), and the connector is made of high-quality high-conductive metal material. 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 for the distance between the panel thickness adjustment to form a terminal block with any number of poles, and isolation plates can be used to increase air gaps and creepage distance. The through-wall terminal block can be firmly installed in the rectangular reserved hole on the panel without any tools, and the installation is extremely convenient. equipment, electrical control cabinets, etc. With good insulation performance and high protection level, users only need to directly connect the external wiring to work, eliminating many unnecessary wiring steps.
