With the development of new energy vehicles in recent years, the new energy vehicles spare parts, charging devices, electrical components of the requirements are getting higher and higher. Electric car drive motor anti-over-temperature protection device, by the protection of the circuit board, protector shell, terminal block three parts, the core part of the protector circuit board. Therefore, the resistance to the terminal test is also an inevitable requirement.

Calculation of Cross - sectional Area and Current Carrying Capacity of Terminal Block Connector

First, the general copper terminal connector carrying capacity Terminals The safety load of the connector is based on the maximum allowable core temperature, cooling conditions, laying conditions to determine the general copper terminal connector of the safe carrying capacity of 5 ~ 8A / Mm2 aluminum terminal block connector with a safe carrying capacity of 3 ~ 5A / mm2 general copper terminal connector with a safe carrying capacity of 5 ~ 8A / mm2 aluminum terminal block connector with a safe load of 3 ~ 5A / mm2 such as: 2.5 mm2 BVV Copper Terminals Recommended values for safe carrying capacity 2.5 8A / mm2 = 20A 4 mm2 BVV Recommended for copper terminal block safety carrying capacity 4 8A / mm2 = 32A

Second, the calculation of copper terminal connector cross-sectional area of the use of copper terminal connector for the safe load of the recommended value
5 ~ 8A / mm2 Calculate the cross-sectional area of the selected copper terminal connector S Upper and lower range: S = <I / 5 ~ 8> = 0.125 I ~ 0.2 I mm2 S ----- Copper terminal connector cross-section mm2 I Load current

Calculation of cross - sectional area and current carrying capacity of general terminal connector
Estimated formula:
Two hundred and fifty times multiplied by nine, go up by a straight to go.
Thirty-five by 3.5, both groups of five points.
Conditions have changed, high temperature Jiujiang copper upgrade.
Piercing the number of two hundred thirty-four, eight seven six fold full load.
Description:
The formula for a variety of insulated wire (rubber and plastic insulated wire) carrying capacity (safe current) is not directly pointed out, but the cross-section multiplied by a certain number that the multiple increases with the cross-section decreases.
