What is connecting wire?

The connecting wire is an important carrier for data and power exchange, and its waterproof performance directly affects the function and service life of the product. With the rapid development of modern society and the continuous advancement of technology, people are paying more and more attention to the safety of various electronic products. The quality and functional requirements of electronic products are also getting higher and higher, and the importance of connecting wires as the carrier of data and power exchange between equipment and equipment, equipment and machinery, and machinery and machinery is self-evident. The waterproof requirement of electronic products has become one of the basic elements of the quality of more and more electronic products, especially the connecting devices that carry wired data and power. The waterproof quality directly affects the function and life of the product.

Brief introduction of connecting wire waterproof
At present, most of the connecting wires on the market do not have the waterproof function, so ordinary connecting wires cannot meet all special environmental requirements. Such as security, aerospace, military and automotive fields. Improving the waterproof technology of connecting wires has become an indispensable part of the upgrade of electronic products, so we must fully understand the waterproof technology of connecting wires.
With the diversification and complexity of the application environment of various electronic products, connecting wires with powerful waterproof functions will be applied to various fields around the world. For example, security, communications, industry, aerospace and navigation, military industry. The improvement of waterproof technology will bring more reliable guarantee to equipment and machinery, and people will use electronic equipment and machinery more safely.

Waterproof rating of connecting wire
According to IEC 60529 and QB/T 1898 standards, the waterproof of connecting wires can be divided into the following levels:
IPX-0: There is no waterproof protection requirement for the product.
IPX-1: Under normal operating conditions, the connecting wire can provide waterproof protection equivalent to 3-5 mm/min of rainfall, and no water leakage for 10 minutes.
IPX-2: The level is basically the same as IPX-1, but it can pass the waterproof test of 15 degrees of upturn in all directions without leaking.
IPX-3: The 60-degree splash water-proof protection provides water-proof protection with a flow rate of 10 liters/sec for 2-5 minutes and a pressure of 80-100 n/m.
IPX-4: The level is basically the same as IPX-3, but it can provide all-round and angular splash and water-proof protection against water leakage.
IPX-5: All-round and angular waterproof protection, providing 12.5 liters/second flow rate for 2-3 minutes and 30n/m pressure waterproof protection against water leakage.

IPX-6: Waterproof protection against big waves can last 2-3 minutes against a depth of 3 meters underwater, with a flow rate of 100 liters/minute, and a pressure of 100 n/m.
IPX-7: It can be soaked for 30 minutes under 1 meter of water without leaking.
IPX-8: Thoroughly waterproof and can be used continuously in water for a long time without leaking.
IP69K: It can withstand the hot steam washout test defined in EN60529 and DIN40050-9.

This can provide protection at a water pressure of 100 bar (1450psi) and a temperature of 80ºC. The pressure is directly applied to the sensor, progressively at 30 degrees (0, 30, 60 and 90 degrees), at each angle for 30 seconds, a total of 120 seconds (2 minutes), to prevent water from entering.
For different waterproof grades, international and domestic standards have corresponding waterproof test methods and specifications, such as GB 4208-2008/IEC 60529-2001 "Enclosure Protection Grade (IP Code)" standard requirements. Nowadays, most connecting wire manufacturers are still at the stage of preliminary understanding of connecting wire waterproof, but a few professional manufacturers of waterproof connecting wire have made corresponding standards and applications for the waterproof level of connecting wire.

Waterproof technology application of connecting wire
The waterproof technology of the cable meets the international waterproof requirements of electronic products. Of course, different waterproof grades must be designed from different materials and structures, so the waterproof design of the connecting line mainly considers the following issues:
1) Design of wire structure:
Wires mainly include conductors, insulation layers, fillers, isolation layers (shielding layers), and wire covers (sheaths). The components must be completely close to each other and have no gaps to ensure that they are leak-proof.

2) The structural design of the connector, the connectors on both sides of the connection line must be sealed when mating with the on-board interface, and the waterproof gasket or spacer is used to make the connector butt completely leak-proof.

3) The combination of wire and connector. The assembly and combination of the wire and the connector mostly use a combination of injection molding and bonding, so that there is no gap between the connector and the wire and no water leakage.
The special materials and structure selected for the third-level waterproofing can achieve the waterproof function without failure within three years, which effectively guarantees the operation and safety of long-term exposure to humid air and deep water equipment. Its applications include:

1) The security camera POE waterproof cable can ensure the reliability and stability of the camera data and power supply placed in the outdoor humid air for a long time.
2) The car 360 rotating lens waterproof cable can ensure the normal operation of the car lens in different environments.
3) The special-shaped waterproof cable can ensure the normal operation of aerospace and deepwater equipment in the supernatural environment.
