Classification and application of terminal blocks
- PRODUCT DETAIL
Classification of terminal
Terminals can be divided into: European terminal series, Plug-in terminal series, Transformer terminal, Building wiring terminals, Barrier terminal series, Spring terminal series, Track type terminal block series, Through the wall type terminal block 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 terminal, 8.4 ring terminal, 11 ring terminal, 13 ring terminal flag series terminal and sheath series. Various types of ring terminals, tube-shaped terminals, wiring terminals, copper strips (2-03, 4-03, 4-04, 6-03, 6-04), etc.
Plug-in terminal
It is made up of two parts plug-in connection, one part presses the line tightly, and then plugged into the other part, this part is soldered to the PCB board. The mechanical principle of the connection bottom 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, and the mounting ears can protect the tabs to a large extent and prevent the tabs from being arranged poorly. 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 buckle and lock buckle. 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 the installation is completed. A variety of socket designs can be matched with different mother body insertion methods. For example: horizontal, vertical or inclined to the printed circuit board, etc., you can choose different methods according to customer requirements. You can choose either metric wire gauge or standard wire gauge. It is the most popular terminal type on the market.
Barrier terminal
It can realize safe, reliable and effective connection, especially in the high current, high voltage environment.
Spring type terminal
It is a new type of terminal using spring-loaded devices. Has been widely used in the world's electrical and electronic engineering industries: Lighting, elevator lift control, instrumentation, power supply, chemistry and automobile power, etc.
Reliable screw connection technology, electronic fuse technology and the latest electrical connection technology are adopted. It is widely used in power electronics, communications, electrical control and power supplies.
Rail terminal
The use of crimping and unique thread self-locking design makes the wiring connection reliable and safe. The appearance design of this series of terminal blocks is beautiful and generous, and can be equipped with a variety of accessories, such as short-circuit strips, identification strips, baffles, etc.
Through-wall terminal
The screw connection technology is adopted, the insulating material is PA66 (flame retardant grade: UL94, V-0), and the connector is made of 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. It can automatically compensate and adjust the distance of the panel thickness to form a terminal block with any number of poles, and an isolation plate can be used to increase the air gap and creepage distance. The wall-through 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. The insulation performance is good, the protection level is high, the user only needs to work directly after the external wiring, eliminating many unnecessary wiring steps. The insulation 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.
WMSTB
The insulation material of the PCB terminal is modified imported nylon (PA66), which has good electrical and mechanical properties. Whether you need to hard wire and hard wire connection, or hard-wire and multi-strand wire connection, or multi-strand wire is connected to the multi-strand wire.
Fuse terminal blocks
The insulating material uses modified nylon (PA66), 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 resists stress crack corrosion. These metal surfaces are also tinned or nickel plated for protection.
All copper terminals can avoid the battery effect of steel metal parts and copper wires in humid environments. There is a connection hole in the middle of the terminal, which can be connected in the center or with side plug-in connectors;
It can be connected to electrical products with a 4mm2 conductor voltage of 800V and a current of 41A.
Experimental terminal
The sliding metal parts that act as switches 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, and the corresponding test terminals can be used for connection testing, and the operation can not be interrupted when measuring current. It can be connected to a control loop with a voltage of 660V and a current of 57A.
Universal terminal block
Color is gray; terminal thickness: 6.2; Conductor section: 0.2-4: 32A: 500V can be installed on U-shaped or G-shaped rails. The double-layer terminal has twice the wiring capacity of the universal terminal in the same position. The upper and lower floors are staggered by 2.5mm in design, which is not only visually organized, but also in the case of upper layer wiring, the screwdriver can be easily connected in the lower area, and the identification is clear.
