Common environmental properties of Motorcycle wire harness made in China include temperature resistance, moisture resistance, salt spray resistance, vibration resistance and impact resistance.

1 temperature resistance

Current electronic connectors are rated for operation from -65oC to 200oC. Since the current generates heat at the contact point when the connector is in operation, resulting in a temperature rise, it is generally considered that the operating temperature should be equal to the sum of the ambient temperature and the junction temperature. In some specifications, the maximum temperature rise allowed by the connector at rated operating current is specified.

2 moisture resistant

Intrusion of moisture can affect the electrical properties of the electrical connector and rust metal parts. The constant damp heat test conditions are relative humidity of 90%~95% (up to 98% according to product specifications), temperature of +40±20oC, and test time of at least 96h according to product specifications. The alternating heat and humidity test is more stringent.

3 salt spray resistance

When the electronic connector is operated in an environment containing moisture and salt, the metal structural member and the surface treatment layer of the contact member may cause galvanic corrosion and affect the physical and electrical properties of the connector. In order to evaluate the ability of electrical connectors to withstand this environment, a salt spray test is specified. It suspends the connector in a temperature-controlled test chamber and sprays it with compressed air at a specified concentration of sodium chloride solution to form a salt spray atmosphere. The exposure time is specified by the product specification for at least 48 hours.

4 resistance to vibration and shock

Vibration and shock resistance are important properties of electrical connectors. They are especially important in special applications such as aerospace and aerospace, railway and road transportation. They are important indicators for verifying the robustness and electrical contact reliability of electrical connectors. . There are clear regulations in the relevant test methods. The peak acceleration, duration and shock pulse waveform and the time of electrical continuity interruption should be specified in the impact test.
