Connector Moulding materials will encounter what kind of test?

The automobile relay fuse box, the waterproof connector, because of its design processing difficulty, is called in the connector domain “The king”.

So today we will take about the use of automotive relays in the process as a Connector Moulding materials will face what test?

In the high temperature environment:
The automobile relay uses in the automobile, the anti-impact, the anti-vibration request is higher, in the harsh environment, the automobile relay normal work produces the energy consumption, will cause the temperature to rise, in the high temperature environment, Connector Moulding materials will soften, or even melt. If the automobile relay is in the low temperature environment for a long time, the plastic insulating material is easy to crack and the resistance to electricity is invalid, so it is very necessary to choose the engineering plastic insulating material of high quality and good quality.

In the hot and humid environment:
In the subtropical, tropical areas, plastic insulation materials also need to consider the hot and humid environment, the relay coil itself is prone to mildew in the hot and humid environment, oxidation corrosion, working performance, and ultimately insulation failure, with serious consequences. Therefore, in the initial product design, material selection needs to fully consider the issue of heat and humidity.

Under mechanical impact:
Automotive Relays are often subjected to mechanical impact during transportation, handling and use, and the Connector Moulding materials can cause structural loosening, damage or even fracture, therefore, the impact resistance of plastic insulating materials should be considered in the material selection process.
