The functional characteristics of Anderson connectors

1. In terms of connection function, insertion and extraction force is an important mechanical performance

Insertion and extraction forces are divided into insertion force and extraction force, and their requirements are different. In relevant standards, there are provisions for maximum insertion force and minimum separation force, indicating that the insertion force should be small, and if the separation force is too small, it will affect the reliability of the contact.

The insertion and extraction force and mechanical life of Anderson plug connectors are related to the quality of the coating on the contact parts of the contact structure and the accuracy of the contact arrangement dimensions

2. The main electrical performance of electrical connectors includes contact resistance, insulation resistance, and electrical strength. ① High quality electrical connectors should have low and stable contact resistance. The contact resistance of connectors varies from a few milliohms to tens of milliohms.

② The insulation resistance is an indicator that measures the insulation performance between the contact parts of an electrical connector and between the contact parts and the housing. Its magnitude ranges from several hundred megaohms to several hundred gigaohms.

③ Electrical strength, also known as withstand voltage or dielectric withstand voltage, is the ability to withstand the rated test voltage between connector contacts or between contacts and the housing.

3. Common environmental performance includes temperature resistance, moisture resistance, vibration and impact resistance, etc

① The current maximum working temperature for temperature resistant connectors is 200 ℃, and the minimum temperature is -20 ℃. Due to the heat generated by the current at the contact point during the operation of the connector, resulting in temperature rise, it is generally believed that the operating temperature should be equal to the sum of the ambient temperature and the contact temperature rise. In some specifications, the maximum temperature rise allowed for connectors at rated operating current is clearly specified.

② The intrusion of moisture can affect the insulation performance of the connection and corrode metal parts.

③ When salt spray resistant connectors work in environments containing moisture and salt, their metal structural components and contact surface treatment layers may undergo electrochemical corrosion, affecting the physical and electrical performance of the connector.

④ Vibration and impact resistance is an important performance of electrical connectors, which is an important indicator for testing the robustness of the mechanical structure and electrical contact reliability of electrical connectors. There are clear regulations in the relevant experimental methods. The peak acceleration and duration of electrical continuity interruption should be specified in the impact test.

⑤ Other environmental properties of electrical connectors include sealing, low air pressure, etc., depending on the usage requirements.
