What Are The Differences Between Metal And Plastic Materials In Heavy-duty Connectors?

The structure of wire connector heavy duty generally consists of a metal contact conductor and a metal outer shell.

Differences between metal and plastic (nylon) TA66 housings:

1. Mechanical life

The mechanical life of heavy duty electric cable connectors refers to the insertion/removal frequency life, which is generally specified by industry standards as 500~1000 times. The circuit resistance of heavy duty automotive electrical connectors and the insulation resistance of heavy duty 12v connectors must not exceed the specified standard values. There is not much difference between metal and plastic casings.

2. Electrical Performance

It has the same rated voltage, contact impedance, and insulation resistance as the plastic outer shell of a heavy duty 12 volt connectors connector.

3. Environmental Parameters

Environmental parameters mainly include ambient temperature, humidity, rapid temperature changes, high atmospheric pressure, and environmental corrosion. The use and storage of 12v heavy duty connector have a significant impact on its performance, so the appropriate metal casing must be selected according to the actual natural conditions, which is better than plastic.

4. Termination Method

The termination method refers to the connection method between the metal contacts of the heavy duty crimp connectors male and female connector and the wires and cables. The same applies to metal and plastic outer shells.

Comprehensive analysis shows that not only is a shielded connector required, but the performance differences between the metal and nylon TA66 plastic housings are also minimal. Compared to metal housings, plastic housings are lower in cost and have a more reasonable structure.
