Analysis of Elinker pressure contact devices
2017-10-27

A pressure contact device, each contact including contact pressure, bending and to contact pressure part of the wires. Electrical contact line Ministry, bent alternately in the direction perpendicular to the line of the Department before and after bending, alternating layout pressure contact to move in different directions. Each pressure contact terminals have the same shape. In another arrangement, contact pressure, including short and long bends, respectively. Line Department of electrical contact. Bent and bent perpendicular to the line in one direction, while alternating arrangement of the bending section. In another arrangement, adjacent pressure contact pressure contact pressures along with the stated routing lines perpendicular to the direction of the contact overlay each other.


In the Terminal, contact force is one of the essential elements. If you do not have sufficient contact pressure, no matter how good the conductive material is useless. Because if contact force is too low and will produce between the conductors and conductive film, and to produce the oxide pollution, the contact resistance increases and cause overheating. A case study of DRTB2.5 pressure box components, only screw exert 0.8Nm of torque, it can produce up to 750N actual contact force, and the size of the force without relationship with conductor cross section. Therefore, the use of Terminal crimping box without any environmental impact, large contact area, permanent joining of the contact force. Voltage drop voltage of the contact point identification of size reduction is one measure of the quality of terminal block. Even for the small screws subjected to torque, voltage drop remains significantly lower than the value of VDE0611 requires boundaries. Meanwhile, exert torque is to vary within a range, voltage drop is almost unchanged. Therefore, although by different operators using a different moment magnitude, without affecting the quality of connection. This is the terminal of line box and the reliability of evidence. Self-locking function of contact force only makes sense on a lasting role in the wire.


Terminal crimping box in this area, with the greatest reliability. Pressure box in the process of tightening the screws with thread up the tabs up above, 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. Pressure wire crimping box 130oC environment made 168 hours aging test, then the vibration test of 20 times the acceleration due to gravity for 168 hours. Completed after these stringent test than the VDE0611, wires disconnected output still VDE0611 from the press box provides as much as six times times the value, while the voltage remains unchanged. This unequivocally shows the Terminal crimping of the maintenance-free box.


Elinker electrical terminals dedicated to the research and development and production, to PCB terminal blocks most known for, hope the majority of users come to consult the discussion!
