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.

06. Excessive compression ratio will cause too much temperature rising at the pressure connection. According to the actual measured terminal compression ratio to less than 40%, the terminal pressure connection resistance will gradually increase. The end of the terminal began to rise slightly.

07. Analysis of terminal compression ratio of hexagonal pressure connectors. First of all, the cross -sectional area of the pressing area should not be less than the cross -sectional area of the nominal conductor;

Secondly, due to the selection of the material thickness of each high -voltage terminal, there will be differences in the selection of the material thickness of each type. According to the terminal compression ratio = 100t/(AT+AC), the AT section area of some terminals is low. The cross -sectional area is less than the cross -sectional area of the nominal conductor. Therefore, the cross -sectional area needs to be as large as possible after pressing. In addition, the analyzing low compression ratio from tensile data will cause the mechanical tensile value of the terminal to decrease, affecting the reliability of the terminal pressure. Summarize the above analysis, consider the reliability of the terminal pressure and terminal resistance. The actual terminal compression ratio is controlled at 65%-75%, and the conductor compression ratio is 65%to 80%.

From the perspective of experimental data, the fluctuations of some resistors and temperature -rising data are related to the terminal plating of the terminal and the terminal contact structure of the terminal. Therefore, it is not enough to reduce the temperature ascending quality alone. It is necessary to pay attention to the daily shelter preservation of the terminal, the quality of the end of the terminal, the end of the terminal plugging, the intersection strength, and the contact area. For products with large temperature rise, high -frequency welding is still recommended. High -frequency welding makes copper melt and adheres to copper at ultra -high frequency. This method has lower resistors.
