Analysis of the classification of wiring terminals

Update:2022-04-25 00:00:00 Visits:177

Terminals can be divided into WUK terminal, European terminal series, plug-in terminal series, transformer terminal, building wiring terminal, fence type terminal series, spring type terminal series, rail type terminal series, through the wall Type terminal series, photoelectric coupling terminal series, 110 terminal, 205 terminal, 250 terminal, 187 terminal, OD2.2 ring terminal, 2.5 ring terminal, 3.2 ring terminal, 4.2 ring terminal, 2 ring terminal , 6.4 Ring Terminals, 8.4 Ring Terminals, 11 Ring Terminals, 13 Ring Terminals Flag Series Terminals and Sheath Series, Various Ring Terminals, Tube Terminals, Terminal Blocks, Copper Tape and Iron Tape (2-03, 4-03, 4-04, 6-03, 6-04) etc. The brands and series of terminal blocks have reached tens of thousands. The brands currently used in the market include: German PHOENIX; Weidmuller; WAGO; JITE (Jet); Taiwan Dingyang; Nanjing Sanmenwan NJSMW; Qianwei Hardware, Changfeng Hardware Link Terminals and other products. Products include PCB plug-in type, solder pin type, spring clamp type, screw press frame type, rail type, traditional through-type terminal block; electronic modules; module boxes, racks, and guide rails.


    Plug-in series terminal block


    It is made up 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 arranged in a bad position. At the same time, this socket design can ensure that the socket can be correctly inserted into the mother body. 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. Various socket designs can be matched with different parent 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.


    European series terminal block


    Represented by German PHOENIX; Weidmuller and other terminals, it is the most cost-effective form of existing wiring technology. The plug-in series terminals are more complete in the JITE (Jite) model. The terminals are made of two parts (male socket and female socket) plug-in connection. PCB board. This wiring design adopts the principle of lifting cylinder or the mechanism of raising the bottom. This anti-vibration design ensures the long-term air tightness of the product and the reliability of the finished product.


    Barrier series terminal block


    It is able to achieve safe, reliable and effective connection, especially in the environment of high current and high voltage.


    spring terminal


    It is a new type of terminal using a spring device and has been widely used in the world's electrical and electronic engineering industries: lighting, elevator control, instrumentation, power, chemistry and automotive power.


    Rail Mount Terminal Blocks


    Adopting reliable screw connection technology, electronic breaking technology and the latest electrical connection technology, it is widely used in the fields of power electronics, communication, electrical control and power supply.


    Rail type terminal block


    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.


    H-type through-wall terminal block


    Using screw connection wire technology, the insulation material is PA66 (flame retardant grade: UL94, V-0), and the connector is made of high-quality high-conductivity metal material. H-type through-wall terminal blocks can be installed side by side on panels with thicknesses ranging from 1mm to 10mm, which can automatically compensate for the distance between the panel thickness and form a terminal block with any number of poles, and can use isolation plates to increase air gaps and creepage distance. The through-wall 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-the-wall solutions: power supplies, filters, electrical control cabinets and other electronic equipment. With good insulation performance and high protection level, the user only needs to directly connect the external wiring to work, eliminating many unnecessary wiring steps. Modified nylon (PA66) is used as the insulating material of WUK series terminals, which has good electrical and mechanical properties. The screw is made of high-strength copper alloy, the conductor is made of electrolytic copper, and the wire frame is made of alloy copper that is resistant to stress crack corrosion. These metal surfaces are also protected by tin or nickel plating. All-copper terminal blocks avoid the battery effect of steel metal parts and copper conductors in wet environments. There is a connection hole in the middle of the terminal, which can be connected in the center or by the side plug connector; it can be connected to electrical connection products with a 4mm2 wire voltage of 800V and a current of 41A


    WMSTB series


    The insulating material of the PCB terminal is made of modified imported nylon (PA66), which has good electrical and mechanical properties, the conductor is made of electrolytic copper, and the crimping frame is made of alloy copper that is resistant to stress crack corrosion. Also tin or nickel plated for protection. Whether you need hardwire to hardwire, hardwire to stranded, or stranded to stranded


    fuse terminal


    Modified nylon (PA66) for insulating materials, with good electrical and mechanical properties. The screw is made of high-strength copper alloy, the conductor is made of electrolytic copper, and the wire frame is made of alloy copper that is resistant to stress crack corrosion. These metal surfaces are also protected by tin or nickel plating. All-copper terminal blocks avoid the battery effect of steel metal parts and copper conductors in wet environments. There is a connecting hole in the middle of the terminal, which can be connected by the center or by the side plug connector; it can be connected to electrical products with a 4mm2 wire voltage of 800V and a current of 41A


    Test terminal


    The sliding metal piece that acts as a switch can withstand the maximum working current through the terminal crimping frame. When switching, use a screwdriver to loosen the screw, move the slider, and the switch position is clear at a glance; there are test sockets at both ends, which are equipped with corresponding The connection test can be carried out at the test tip, and the current measurement can be performed without interruption of operation. It can be connected to a control loop with a voltage of 660V and a current of 57A.


    WUK universal double-layer terminal block


    The color is gray Terminal thickness: 6.2 Conductor cross section: 0.2-4: 32A: 500V It can be installed on U-shaped or G-shaped rails. The design of the two layers is staggered by 2.5mm space, which is not only visually organized, but also in the case of wiring on the upper layer, the screwdriver can be easily connected in the lower layer area, and the marking is clear.
