Wiring System

 

Task Terminal system is the mechanical and electrical wires reliable connection. Terminal uses press frame can effectively implement this feature. The Clamp is hardened and passivated galvanized steel, can withstand the tremendous torque of the screws can be firmly pressed steel wire . Copper plated flexible conductive sheet tin - lead alloy , to ensure air-tight , low resistance , permanent connection with the wire . The following advantages of the wiring system loved by the users , and are widely used :

 

Contact surface , and the contact pressure, and can be any lateral contact .

 

With self-locking , seismic, locking feature

 

Testing jack can be installed , no maintenance

 

Absolutely airtight contact points , corrosion

 

Strands are not allowed to crimp the ends can be directly connected

 

Small voltage drop

 

Voltage drop size is also the identification of the contact point scale BLOCK quality. Even a small torque imposed on the screw , the value of the voltage drop is still well below the required limits VDE0611 . Meanwhile , the torque applied in a wide range, the voltage drop is almost unchanged. Thus , although different moments of different sizes are used the operator , but will not affect the quality of the connection . This is yet another proof of the use of terminals Clamp reliability .

 

Self-locking feature

 

Large contact force only meaningful lasting effect on the wire . Terminal uses press frame in this regard with the greatest reliability. In the process of tightening the screws threaded clamping yoke above the tongue upward bounce , thereby producing a reaction to the screw . Due to changes in temperature caused by the diameter of the wire frame itself, the elasticity of the pressure to offset , so no need to re- tighten the screws . Pressure to the pressure on the wire frame 168 hours aging test at 130oC for environment behind , then Youyi 20 times the acceleration of gravity for 168 hours of vibration tests. Upon completion of these tests are more stringent than VDE0611, leads from the pressure of the extraction force wireframe still higher than a predetermined value VDE0611 six times , and the voltage drop remains unchanged . This unequivocally shows the terminal voltage wireframe using maintenance-free .

 

Tightness

 

A variety of environmental factors such as temperature, air humidity, long role in the terminals , so the terminal must have the ability to withstand the test of adverse environmental factors, tests and practical experience in accordance with the provisions of Chapter 76 of DIN41640 made ​​to prove that even in under no circumstances connected crimp ends soft wire , Clamp can maintain its airtight performance .
