The performance of automotive connectors is reflected in three dimensions, namely, mechanical performance, electrical performance and environmental performance.
In terms of mechanical properties, it mainly includes pulling force, machine city life, sending resistance, machine reduction and so on. Inserting and pulling force is divided into inserting force and pulling force, the maximum value of the insertion force and the minimum drawdown life of the pulling force are generally referred to as the transmission life, which is a durability index, and the transmission force and the reduction life of the automotive connector are usually related to the quality of the contact part and the dimensional accuracy of the arrangement: Because the vehicle is in a dynamic environment for a long time during the process, the vibration resistance and the mechanical impact can effectively reduce the surface wear caused by the friction of the Westopol parts, improve the reliability of the product, and then improve the safety of the vehicle system.
In terms of electrical performance, it mainly includes contact electricity, insulation electricity, voltage, anti-electromagnetic EMC, signal high reduction, current carrying capacity, and other requirements. The electric positive refers to the electric light generated between the contact surface of the male and female terminals of the car connector, which will directly affect the signal transmission and electrical transmission of the electrical equipment in the car. If the electric return is too large, it will lead to higher temperature rise. Affect the service life and reliability of the connector insulation resistance refers to the application of voltage in the insulating part of the car connector, so that the surface or internal source electrical method and present the electrical value, if the edge of the electric light is low, can be solved to form a reverse circuit, increase the rate of loss caused by labor interference, excess leakage current may destroy insulation, endanger the safety of anti-electromagnetic labor interference, that is, electrical compatibility, It means that no electrical spoilage is caused by other elements. It is particularly important in automotive electronic systems to maintain the original performance when subjected to electromagnetic interference from other devices.
In terms of environmental performance, automobile connection dew is required to have temperature, moisture resistance, salt dew resistance, corrosion resistance and other properties. Temperature resistance to the car connection suspected working temperature requirements, because the car connector work, the current at the contact point of heat, resulting in temperature rise, if the temperature rise is too high than the normal working temperature, easy to lead to short circuit, fire and other serious accidents, moisture resistance, salt dew resistance, corrosion resistance gas can avoid the metal structural parts of the car connector, connectors occur oxidation, corrosion. It affects the contact resistance.
