In the Terminal, the contact force is one of the essential elements. If you do not have sufficient contact pressure, no matter how good the conductive material it is useless. Because, if the contact force is too low, between conductors and conductive film will result in displacement, resulting in oxidative pollution, make the contact resistance increases and cause overheating. A case study of pressure box components, simply put 0.8Nm of torque on the screws, they can produce up to 750N actual contact force, and had no relation to the size of the force and the conductor cross section. So, the Elinker press box without any environmental impact, large contact area, contact force permanent joint.

Point of contact voltage drop size identification terminal block one measure of quality. Even screws subjected to very little torque, voltage drop remains significantly lower than the value of VDE0611 requires boundaries. At the same time, torque is applied on a large scale changes, the voltage drop is almost unchanged. Thus, while using torque by different operators in different sizes, but will not affect the quality of connection. It is the reliability of the Elinker press box and a certificate.

Contact force only makes sense on the lasting effect on the wire. Elinker Groove boxes with maximum reliability in this respect. Groove box in the process of tightening the screws with thread above the tabs upward bounce, the resulting reaction of a screw. Wire diameter change due to temperature offset by crimping elastic box itself, there is no need to tighten the screws again. Crimping of wire box on 130oC environment unsafe for 168 hours aging test, and then at 20 times the acceleration due to vibrations in the 168-hour test. Upon completion of the rigorous than the VDE0611 test, the uplift of the wire from the wire box rating is six times higher than VDE0611 times as much, and voltage drop remained unchanged. This unequivocally shows the Elinker Groove box, maintenance-free.

Elinker observed a variety of environmental factors such as temperature, air humidity for many years acting on the terminal block, terminal blocks must have the ability to withstand adverse environmental factors tests made under the provisions of chapter DIN41640 of the experiments, as well as practical experience has shown that, even in the connection was not soft wire crimping head cases, pressure box can maintain its air-tightness.
