UK Series Din Rails Spring Clamp Terminal Blocks
Nylon
Insulated parts is made of modified Nylon PA66 and have good electric and physical performances.
- Resistivity (0×mm): >1015
Dielectric strength (KV×mm): 30 - Comparative tracking index (CTI,V): 450
- Long time working temperature (°C): 100
- Lowest static working temperature (°C ): -50
According to UL 94, the flame retardant grade of the modified PA66 is between HB and V0.
Adopted PA66 material free of halogen, during burning it will not produce corrosive acid rain gas, more over PA66 is of good weather proof, does not provide oxygen or other biological element for microbe, namely some insulating parts made of this material will not do harm to its performances even if white ant, anaerobic bacteria, or fungi exist.
PA66 can well withstand most oil and grease, alcohol, and common detergent such as carbon tetrachloride.
Manufacturing equipment: Provided complete automatic plastic injecting equipment and punching machine, these good equipment guarantee the product with high quality
Electric Current Bar
The flat and straight wire compressing frame can keep good connection with cable even if the cable is very small.
The thread in current bar sweep off the oxidation layer on the cable surface to make connection enough to withstand pulling force.
The clamp structure is firm, has low tolerance during production, high contacting pressure, all of these ensure solid connection, even in the corrosive surroundings.
Metal Parts of Terminal Blocks
Each metal part of screw type terminals requires different mechanical strength, the alloy material for these metal parts is different as well, the screw made of high strength copper alloy, conductor is electrolyzed copper, wire compressing frame made of stress resistant, crack proof, anti-corrosive copper alloy, the surface of these metal parts will be coated with tin or nickel layer.
The terminal block of complete copper material can prevent the battery effect that produce between steel part and copper conductor when they become damp, finally it can avoid electric corrosion and its bad influence unsecure electrical connection and screw being rusted.
Screw Self-Locking
UK full copper terminal blocks adopted the theory of «Reakdyn» to prevent screws being loose automatically, for optimized terminals with rated cross sectional area up to 10mm2, their wire compressing frame constructed of lifting cylinder structure, while tightening the screw, the screw push the conductor and make wire compressing frame moving upward, finally the cable clamped solidly with the conductor in the frame. And due to high piercing force from the terminal, the cable can contact deeply into the tinned layer of conductor, in such case the transitional resistance in 4mm terminal has only 0.30, smaller than the required data of IEC947-7-1/EN609477-1 standard, the upper «Reakdyn-gap» can realize screw selflacking via such structure, increase the torque to tighten screw, lifting cylinder engenders elastic distortion, which will make friction increase gradually in the screw.
DIN Rail
The rail can be used to fix electric and electronic connectors quickly and reliably.
Central Connector
The rail can be used to fix electric and electronic connectors quickly and reliably.
Clapboard
Isolated plate TS can used to perform electric and visible isolation between directly adjacent bridged parts in the central of terminal block. If electric clearance and creepage distance can’t be reduced, the two sides of central bridged joints shall be added with isolated plates, these plates can be inserted later and clamped solidly, not occupying the space of rail.
Grouping Clapboard
Grouped isolating plate ATP projecting out terminal configuration, easy to be sorted.
Fixed Bridge
Channel bar of fixed bridge joint FaRI has screws, which put on small sleeve to avoid losing, the fixing number of this bridge Joints is 2-10 bits.
Side Plug-In Connector
Side inserted bridge joint EB together with conductor can be pressed to connect with terminal, after side inserted bridge joint, the permissible section area of conductor has to be smaller. 10-bit bridge joint can be sheared as any number bit less than 10-bit. Moreover it can cut off the single metal tooth of the bridge joint and jumped to connect the terminals. There has insulated layer on the tooth back of bridge joint to prevent electric touch.
End Stop
Termination fixing part is suitable for G and Th type mounting rail, for positioning two sides of terminal block.
Mark Tag
All combination terminals in the mounting channel with markings can be quickly and well marked with 28 marking system.
