High-quality electronic wires and wire harnesses use high-quality electronic wires
1. Sufficiently thick copper wire, strictly in accordance with international standards! Made with high-quality oxygen-free copper, it has low resistivity and good conductivity. Using a traditional canned process to eliminate internal stress, it avoids the problem of uneven wire core density and hardness during production.
2. High-strength insulation, not easy to peel off or break. Using high-standard insulation materials, compared with other ordinary wires, it has good flexibility and is easy to bend, ensuring that the wire is not easily broken under external force impact or frequent bending, making it safer and more reliable.
3. Made of 100% pure copper, the surface of the copper wire is bright, the resistivity is low, the conductivity is high, it is not easy to generate heat, and it is environmentally friendly and safe!
II. Terminals used in wire harness products are all self-produced and processed!
1. Made of high-quality copper alloy (phosphor bronze). Phosphor bronze has a bright luster and is a copper alloy with good conductivity, is not easy to generate heat, ensures safety, and has strong fatigue resistance. The material of phosphor bronze can compensate for the poor ductility of brass. Phosphor bronze has better elasticity, high temperature resistance, and corrosion resistance, making the product safer and more durable. Therefore, good terminals are mostly made of the best phosphor bronze.
2. Terminal plating, gold-plated or tin-plated. Gold plating has a very strong anti-oxidation function, but it is slightly more expensive. Considering the cost, if the customer has no special requirements, gold plating is generally not used. Good plating has a particularly bright surface and is not easily oxidized, thus extending the service life of the product! Poorly plated terminals are prone to oxidation after a long time, and the surface will rust, directly affecting the service life of the product.
III. Connector shells used in wire harness products are all self-produced and processed.
1. The insulation material used in the production of shells is PBT/Nylon 66. PBT or Nylon 66 material has good fluidity and smoothness, good electrochemical resistance, good thermal performance, and good fluidity and impact resistance. Poor insulation materials are prone to heat generation under load, have poor temperature resistance and poor hygroscopicity, and are easily deformed, short-circuited, and burned.
2. The connector shell has a smooth and bright surface. Poor-quality shells will have more burrs, making it difficult to insert and pull out, resulting in insufficient contact and easy contact failure.
3. The connector shell has good flame retardancy. Even if the flame is large, it will not cause direct combustion, which is absolutely environmentally friendly and safe.
