Why choose liquid silicone encapsulation for new energy vehicle connectors?

When exploring the underlying reasons for choosing liquid silicone encapsulation for new energy vehicle connectors, we must first delve into the rapid development background of the new energy vehicle industry and the key role that connectors play as core components in this field. As an important trend in the future automotive industry, the technological innovation of new energy vehicles is not only reflected in battery technology, motor drive and control systems, but also in the optimization and upgrading of every detail component. Among them, the performance and reliability of connectors, as the bridge between electrical energy and signal transmission, directly affect the safety, efficiency and service life of the entire vehicle.

Special requirements for connectors for new energy vehicles

Compared to traditional fuel vehicles, new energy vehicles have more complex and stringent requirements in terms of electrical systems. On the one hand, the high voltage and high current characteristics of battery packs require connectors to have excellent electrical performance, such as low resistance, high withstand voltage, and strong current carrying capacity; On the other hand, the working environment of new energy vehicles is diverse, including extreme conditions such as high temperature, low temperature, humidity, and vibration, which pose extremely high challenges to the weather resistance, sealing, and durability of connectors. In addition, with the advancement of automotive intelligence, connectors need to carry more data transmission tasks, and the stability and anti-interference ability of their signal

transmission are also crucial.

Analysis of the advantages of liquid silicone encapsulationIt is in this context that liquid silicone encapsulation technology, with its unique performance advantages, has gradually become the preferred solution in the field of new energy vehicle connectors. Below, we will analyze in detail the reasons for its selection from several aspects:

1. Excellent electrical insulation performance

Liquid silicone has good electrical insulation properties, which can effectively isolate current and prevent short circuits and leakage. In the high voltage environment of new energy vehicles, this characteristic is particularly important as it ensures the safety and stability of the connector under long-term high load operation.

2. Excellent weather resistance and durability
Liquid silicone materials have excellent resistance

to high and low temperatures, and can maintain stable physical and chemical properties over a wide temperature range of -60 ℃ to+200 ℃, unaffected by changes in environmental temperature. At the same time, its excellent aging resistance, UV resistance, chemical corrosion resistance and other characteristics enable connectors coated with liquid silicone to operate stably in various harsh environments for a long time, greatly extending the service life of the product.

3. Good sealing and waterproof/dustproof ability

New energy vehicle connectors need to face complex and ever-changing external environments, such as rain, dust, etc. The liquid silicone encapsulation technology precisely controls the flow and solidification of liquid silicone, forming a dense coating layer that effectively isolates harmful substances such as moisture and dust from the outside, ensuring the sealing and waterproof and dustproof capabilities of the connector, thereby maintaining the normal operation of the electrical system.

4. Excellent seismic and impact resistance performance

During the operation of new energy vehicles, especially electric vehicles, due to the large weight of the battery pack and fast acceleration of the vehicle, there will be significant vibration and impact on the connectors. Liquid silicone encapsulation has good elasticity and toughness, which can effectively absorb and disperse vibration and impact energy, protect the internal structure of the connector from damage, and ensure stable and reliable connection.

5. Environmental Protection and Sustainability

With the global emphasis on environmental protection and sustainable development, the new energy vehicle industry is also paying more attention to environmental friendliness in material selection. Liquid silicone, as a non-toxic, odorless, and recyclable environmentally friendly material, meets international environmental standards. Connectors coated with liquid silicone are not only safe and reliable during use, but also reduce environmental pollution during disposal.
