What Types Of Terminal Blocks Are There?
Cable Lugs can be divided into WUK terminal blocks, European terminal blocks series, plug-in terminal blocks series, transformer terminal blocks, building wiring terminals, fence terminal blocks series, spring terminal blocks series, track terminal blocks series, through-wall terminal blocks series, photoelectric coupling terminal blocks series, 110 terminals, 205 terminals, 250 terminals, 187 terminals, OD2.2 round ring terminals, 2.5 round ring terminals, 3.2 round ring terminals, 4.2 round ring terminals, 2 round ring terminals, 6.4 round ring terminals, 8.4 round ring terminals, 11 round ring terminals, 13 round ring terminals, flag-type series terminals and sheath series, various types of ring terminals, tubular terminals, terminal blocks, copper strips and iron strips (2-03, 4-03, 4-04, 6-03, 6-04), etc.
The plug-in type is connected by two parts, one part presses the wire tightly, and then plugs it 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 to both ends of the socket. The mounting ears can protect the tabs to a large extent and prevent the tabs from being arranged in a poor position. At the same time, this socket design can ensure that the socket can be correctly inserted into the mother body. The socket can also have assembly buckles and locking buckles. The assembly buckle can be more firmly fixed to the PCB board, and the locking buckle can lock the mother body and the socket after installation. Various socket designs can be matched with different mother body insertion methods, such as: horizontal, vertical or inclined to the printed circuit board, etc., and different methods can be selected according to customer requirements. Both metric wire gauge and standard wire gauge can be selected, which is the most popular terminal type on the market.
The fence type can achieve safe, reliable and effective connection, especially in high current and high voltage use environments. It is widely used.
The spring type is a new type of terminal block using a spring device, which has been widely used in the world's electrical and electronic engineering industries: lighting, elevator lifting control, instrumentation, power supply, chemistry and automotive power, etc.
Track installation uses reliable thread connection technology, electronic breaking technology and the latest electrical connection technology, and is widely used in power electronics, communications, electrical control and power supply.
Track type uses crimping and unique thread self-locking design to make wiring connection reliable and safe. This series of terminal blocks has beautiful appearance design and can be equipped with a variety of accessories, such as short-circuit pieces, identification strips, baffles, etc.
Through-the-wall type uses screw connection technology, the insulation material is PA66 (flame retardant grade: UL94, V-0), and the connector uses high-quality high-conductivity metal materials.
H-type through-the-wall terminal blocks can be installed side by side on panels with thicknesses of 1mm to 10mm, and can automatically compensate for the distance of the panel thickness to form terminal blocks with any number of poles, and isolation plates can be used to increase air gaps and creepage distances. The through-the-wall terminal blocks can be firmly installed in the rectangular reserved holes on the panel without any tools, and the installation is extremely convenient.
H-type through-the-wall terminal blocks are widely used in some occasions that require through-the-wall solutions: power supplies, filters, electrical control cabinets and other electronic equipment. With good insulation performance and high protection level, users only need to connect external wiring to work, eliminating many unnecessary wiring steps. The insulation material of WUK series terminal blocks is modified nylon (PA66), which can connect 4mm2 wires with voltage of 800V and current of 41A.
