Classification and application of terminal blocks
- PRODUCT DETAIL
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.
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.
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.
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.
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.
