Electric Conduction Material:
As electronic conduction material . Cooper has outstanding electronic and mechanical effects .copper with different natures can meet SUPU terminal block requirments for electric conduction materials with different forming and without rupture danger with stress according to the requirment of electric application . Copper conductor is plated with tutania on its surfaces ,and is makes it a better electric contactor with minor electric resistance.Tutania-plating has good electric conducting and anticorrosive effects.Tutania surface processing can protect the antiwear ability between terminal blocks on printed circuit boards (PCB) and welding needles on connectors . In order to increase their antiwear ability ,connectors are also plated with tutania to keep the same lasting welding effect.
Electrical Insulating Material :
In order to meet different products' practical need ,We choose different materials according to specific application .As the housing of the terminal blocks and connectors . Nylon 6.6 is the first option for excellent electrical insulating material. It is also accepted by almost all the international testing organizations. Nylon has been used as the basic materials for SUPU terminal blocks because of its outstanding antipuncturing ability against leaking current, which has been up to CTI 600 according to IEC 112 and thus would reduce the moving distance of air and leaking current . Nylon 6.6 has springiness ,rigidity and is resistant to most chemical corrosion and has been ranked as catalogue extinguishing V-O or (V-2). Character-changing nylon 6.6 adopted by SUPU terminal blocks do not contain halogen ,fluorocarbon, chlorine-carbohydrate ,silicon,asbestos .cadmium ,formaldehyde, so all electrical insulating materials applied in SUPU terminal block do not contain poisonous elements.
Spring clipping Material :
All clipping spring used by SUPU terminal blocks is of high-quality and careful-elected nickel-chrome spring steel .CrNi.It has good tensile strength and corrosion resistant property proved by many years of practical experience. It can resisit salty fog form ocean, exhaust gas in cities and industrial gas ,such as: sulfer dioxide and hydrogen sulfide. When it is common 22.C. It can resist 30% brine solution aand 30% phosphatic acid .
Comparison Between Spring Clipping and Screw Clamping :
SUPU's practical research for terminal blocks in wide range of clients has approved , taking manual wire-connecting for example ,that it costs spring cliping 50% less time than of screw clamping . And spring cliping still holds the advantages when it comes to electric screwing .(In many cases in the preparation for conducting wire for example .one can save more time if one can omit some preparation steps such as pressing the end of the wire tightly ,connecting cold joints or tin applying ,ect.)
Screw clamping connection "wholly depends on manual operator" , that means its tightness is decided by operator's judgment. This will be more or less managed by operators or by certain values from special torsion screw driver manufacturers . When connecting wires on-site ,it is even more difficult to assure proper tightness of screw clamping .Spring 's characteristic of clipping automatically may allow unskilled operators to finish connecting with perfect joint . Whoever operates will make the same exact joint and the tool is just a standard screwdriver,SUPU spring terminal block has different connecting modes form front ,side and 45.angle.
Connecting steps : insert a tool --insert conducting wire without insulating coat--extract the tool and the conducting wire is clipped automactically .
SUPU spirng terminal block--adjust clipping power automatically according to different diameters of conducting wire ,reach the same high-quality connection no matter operators are skillful or not .
SUPU spring terminal block--airtight connection ,minor contact resistance ,anticorrosive ,anti-vibration ,shock resistance .
Advantages of spring clipping terminal block :
Unlike screwing terminal block , spring terminal block does not need to be checked ofen or rescrewed because of the loose connection for virbration , temperature circulation ,or broken screw thread . With its fixed reliability ,spring terminal block will decrease machine halting time and maintance frequency. According to statistics that 35%--50% equipemnt maintance is because of bad connection .Considering the high maintance cost and the loss of manufacturing time , saving in such a project is very necessary .
For security ,reliability and convenience of obstacle avoidance,many industrial standards and and national standards regulate that "every clamping point can only be with one onne conducting wire" .SUPU spring terminal block can provide clinets with terminal blocks that are with two-wire connector,. Three- or four-wire connectors . In both cases,every wire has its own tight connection joint and it does not take much time space than two-wire terminal block.
Spring clipping is designed to have proportional clipping power with differebr types of wore . More think the wire is , more powerful clipping is . Combining specail curved surface of guide tube with flat and smooth spring surface. It can give tight connection without damaging wires . At the same time, the angle of spring is created to be with special property, and the clipping will be more powerful when it is pulled or drawn .
There is a complete entrance for conducting wire in SUPU spring terminal block and connectors , which can hold wires tightly , combining special spring properties , outer covering of SUPY can avoid twisted lines by fixing conducting wire in contact are automatically . |
