828920-1 Cable Single Wire Seal For Amp Tyco Circular Connector

According to the VW60330-2013 standard, the calculation of the compression ratio only contains that the conductor does not include the compression of the terminal, and it can more intuitively reflect the existence of the conductor. When the compression ratio is ≤100%, there should be no gap. We can call it a wire compression ratio.

According to the SAE/USCAR21-2014 standard, the calculation of the compression rate contains the compression of the conductor and the terminal. To facilitate data comparison, this article defines the terminal compression ratio = 100t/(AT+AC).

The two calculation methods have their own advantages. 01. According to Table 1, when the compression ratio of the 3#product conductivity reaches 104%, the tension has reached 50mm² specified in QC/T29106-2014, and the wire tension is ≥2 700N. There are large hidden safety hazards, so high -pressure terminals cannot use tensile for force as the standard for judging quality.

02. The resistance number in the table does not completely correspond to the temperature rise trend. It should be a fluctuation caused by inconsistency caused by inconsistency caused by the end of the terminal individual contact and the oxidation of the terminal plating. However, from the perspective of the general trend, the corresponding relationship of the lower the resistance, the lower the temperature, the lower the temperature.

03.7#The terminal compression ratio is 73%. The conductor and the surface of the terminal will be aerobic. The oxide layer will gradually be destroyed with the decrease in the compression ratio. , Make the fusion of copper wire closer, and the temperature rise also reduces a slightly reduced, indicating that the terminal compression at this time is more suitable.

04. From the perspective of temperature rise value fluctuations, the impact of pressure connection on temperature rise can reach between 10 ° C. This has a greater impact on high -pressure terminals.

05.10#In the case of 60%of the product terminal compression ratio, the cross-sectional area of the conductor theory at the terminal pressure connection is only 30mm². According to the compression ratio of the SAE/USCAR21-2014 terminal, It should also be included. In fact, the cross -sectional area and terminal of the conductor and terminal of the conductor and terminal are 66.97mm², which is greater than 50mm² nominal conductor sectional area. Calculation method of terminal compression ratio.
