端子金属部分Metal partsofTerminal blocks

由于对螺钉型端子各个金属部分的机械强度要求各异，构成他们的合金亦各不相同，螺钉用高强度铜合金制成，导电体由电解铜制成，压线框由抗应力裂缝腐蚀的铜合金制成，这些金属部件的表面还镀锡或镀镍加以保护。全铜接线端子排可避免钢制金属件和铜导线在潮湿情况下的电池效应。由此可避免电腐蚀及其后果一一不可靠的电连接及螺钉锈死现象的出现。

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 ofstressresistant， crack proof,anti-corrosive copper alloy,the surface of these metal parts wil 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.

螺钉自锁 Screw self-locking

UK全铜接线端子利用“Reakdyn原理”防止端子螺钉自松脱。在额定截面至 1 0 \mathsf {mm } 2 的优选端子系列中，压线框均采用升降筒式结构。他们的作用原理是以所谓“升降筒原理”为基础的。拧紧螺钉时，螺钉顶在导电体上而使压线框向上运动，由此使压线框中的导线帖紧导电体并最终被夹紧。由于端子具有很高的接触力可使导线嵌入导电体柔软的锡镀层中。这样在 4 \mathsf {mm } ^ { 2 } 端子上得到的过渡电阻仅为 0 . 3 \Omega ，明显低于IEC947-7-1/EN60947-7-1标准要求的最低值，在这种压线框结构中通过升降筒上部的“Reakdyn-缝隙”实现螺钉自锁。增大扭矩拧紧螺钉，升降筒发生弹性形变，由此实现的自动步进自锁使得螺纹摩擦力逐步增大。

VK full copper terminal blocks adopted the theory of "Reakdyn" to prevent screws being loose automatically， for optimized terminalswith 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 4mm2 terminal has only O.3Ω,smaller than the required dataof IEC947-7-1/EN60947-7-1 standard，the upper "Reakdyn-gap"can realize screw self-locking viasuch structure,increase the torque to tighten screw, liftingcylinderengenders elastic distortion, whichwill make friction increase gradually in the screw.

ST系列回拉式弹簧接线端子SERIESDIN RAILS SPRING CLAMPTERMINALBLOCKS

技术创新

我们致力于连接器行业创新，着力于产品的技术革新，而VST系列回拉式弹簧接线端子则满足了人机操作的和谐。它以弹簧压力代替螺丝式的导线连接技术为用户带来许多突出的好处。接线端子和连接器可以自行适应插入导线的尺寸，为每一种尺寸的导线提供最佳的紧固力。从而不管配线工的技术如何，都能保证每一次的的连接是安全和可靠的。同时，接线端子即使在最恶劣的工作条件下，都具有高超的耐腐蚀，抗振动和耐热的性能。

Technology innovation

Weare devoting ourselves to technical innovation for electric connectors，VST series cage type spring terminal can serve with human-machine operating demand，its spring pressure instead of terminal screw for connecting conductor，which will give so much out-standing benefit to users.The terminals and connectors made by CMSMS company，can accommodate the length of the conductor to be inserted by itself, to provide best tightening strength for conductors with different sizes,no matter how much the wiring worker knew, it can guarantee safe and reliable connection every time.Meanwhile,even if in severe working conditions,our products can still with stand corrosiveness,vibration,and temperature well.

回拉式弹簧夹持与螺钉夹持在操作上的差异性

螺钉连接“依赖于操作人员”换句话说，关于螺钉的紧度，需要操作人员的判断。这可能多少有点受控于培训人员或特定转矩螺丝刀的工厂设定值。当在现场接线时，则更难保证适当的螺钉紧度。

回拉式弹簧的自动夹紧特点允许不太熟练的操作者完成优质的连接。无论谁操作都可以完成精确而一致的接线。而其工具只是一支标准的螺丝刀，回拉式弹簧的接线端子具有正面接线和侧面接线二种形式。

The difference of installation between cage type spring terminal blocks and screw terminal blocks

Screw connection tightness depends on the operator,influenced by the operator and default of screwdriver.When on assembly site its tightness can't be guaranteed further.

Automatic clamping of cage type spring terminal make learner able to perform good connection, everyone can do exquisite wiring connections,but onlystandard screwdriverneeded, this terminal can be connected on front or side face.

回拉式弹簧的性价比

Cost and performance ratio of cage type spring terminals.

不像大多数螺钉式接线端子那样，对于回拉式弹簧连接器不需要检查或重新拧紧，因扰动、温度循环，绞线断股等造成的而变松的接点。回拉式弹簧的固有可靠性会减少停机时间和用户的维修请求次数。大多数维修部门估计 3 5 - 5 0 % 的维修请求是接点不良的结果。考虑维修的高费用和生产时间的损失。故此项节约是很有意义的。

Not like screw terminal,after being connected the cage type spring terminals does not need inspect its looseness and tighten up screw due to vibration, temperature circulation,broke strand and etc.solid reliability of cage spring terminal will reduce the offduty time and repairs. Statistically approximate 35- 5 0 % repairs resulted from bad connection，in consideration of high repair cost and losing working time,consequently this advantage is very useful.

回拉式弹簧的保持力与检测机构的显著特征

Holding force and of cage spring and out standing feature of test lab

大多数检测机构对螺钉和无螺钉接线端子，有要求其对导线持有最低的保持力要求。如图1所示，对回拉式弹簧夹持的测量的拉拔值符合并在大多数情况下远远超过这些值。

Most of test labswill require the lowest holding force for screw type and screw less terminals,as per Pic 1, the pulling force on connection with cage type terminal can completely meet with requirements,and further more than specified value.

回拉式弹簧接线的优点

最优化的接线方式，使回拉式弹簧端子正面接线节省了两个行线槽之间所需的连接空间，双桥接井可实现链式桥接，配合相应附件进行测试与标识。

Advantages of cage spring terminal

Spring distortion will be restricted from upper surface of cage and a plate of insulating parts in enclosure,to prevent spring being distorted too much, consequently even if operator without any experiences, can't damage the spring.
