What's the difference between metal and plastic connectors?

Waterproof connector is a new type of waterproof connector, which can operate well in high temperature, high humidity, high vibration and high impact environment, while plastic connector does not have these characteristics. Next, let Xiaobian show you the difference between metal and plastic connectors for waterproof connectors.

1. Mechanical life: The mechanical life of waterproofing lines refers to the number of insertion and removal life, which is usually specified by industry standards as 500 to 1000 times. The contact resistance, insulation resistance and withstand voltage of the waterproof wire should not exceed the specified standard value when it reaches the specified mechanical life, which is not much different from the plastic case.

2. Electrical performance: rated voltage, rated current, contact resistance, insulation resistance, etc. according to the specified standard values, this metal and plastic shell is the same.

3. Environmental parameters: Environmental parameters mainly include environmental temperature, humidity, temperature changes, atmospheric pressure and corrosive environment. The environment in which waterproofing lines are used during storage and transportation has a significant impact on their performance. Therefore, it is better to choose the appropriate metal shell according to the actual environmental conditions.

4. End-connection method: End-connection method refers to the connection method between the male and female waterproof connector and the hardware contact part of the wire and cable. Metals are the same as plastic shells. In addition to shielding joints, the performance of metal and nylon TA66 plastic shell has little difference. Plastics are cheaper than metal shells and have a more reasonable structure.
