Information

In the new energy circular contact, the contact force is one of the basic premise. If there is not sufficient contact stress, the use of the best conductive material will not help. Because, if the contact force is too low, there will be a deviation between the wire and the conductive sheet, which will cause the air to oxidize the environment and cause the loop resistance to expand and cause over-temperature.

new energy circular contact cost

Taking the DRTB2.5 crimping frame part as an example, it is only necessary to increase the torque of 0.8Nm to the screw, which can cause a specific contact force of 750N, and the magnitude of the force is independent of the cross section of the wire. Therefore, the use of cold-pressed terminal crimping frame has a permanent connection that will not suffer from all environmental hazards, large total contact area, and large contact force. The voltage drop size of the point contact with small voltage drop is also one of the limits to distinguish the quality of the wiring seat.
Even if a small torque is applied to the screw, the value of the voltage drop is still much smaller than the limit specified in VDE0611. At the same time, the increased torque is shifted over a very wide range, and the voltage drop is essentially unchanged.
Therefore, although the torque size applied by different actual operators is different, it is not easy to compromise the quality of the connection. This is another confirmation of the stability of the crimping frame adopted by the new energy circular contact.
