How to choose muti-pole connectors?
Power connectors currently on the market are divided into three types: unipolar connectors, bipolar connectors and three-pole connectors.
Uni-polar connectors are single-terminal plugs that can be combined in any combination of positive and negative poles. Common sizes include 45A, 75A, 120A, and 180A (amps).
Three types of material for terminal:
• Pure copper has good conductivity, strong ductility, is not easy to break when crimping, and is more expensive.
• Brass, on the other hand, has poor conductivity, high hardness, and is more likely to break when crimped, but it is cheap.
• Silver has excellent conductivity but is expensive, while nickel is less conductive and less expensive.
Bipolar connectors are positive and negative pins, which can be inserted in any color, regardless of gender. Common sizes include 50A, 120A, 175A, and 350A (amperes). As far as the connection methods of Anderson connector power connectors are concerned, the following three types are commonly used:
1.[Strongly recommended] Pressure connection: The pressure connection should be able to produce metal inter diffusion and symmetrical deformation between the wire and the contact material, similar to a cold welding connection. This connection method can obtain good mechanical strength and electrical continuity, while also being able to withstand harsher environmental conditions. Currently, it is generally accepted that the correct pressure connection should be welded to the arm, especially in high current applications.
2.[General recommendation] Soldering: The most common connection method is soldering. The most important aspect of a solder connection is that there should be a continuous metallic connection between the solder and the surface being soldered. The most common coatings for connector solder ends are tin alloys, silver and gold.
3.[Not recommended] Winding: Straighten the wire and wind it directly on the joint with the diamond-shaped winding post. When winding, the wire is wound and fixed in the diamond-shaped corner of the contact winding post under controlled tension to form an airtight contact.
