The widespread use of waterproof connectors in modern electronic devices reflects their important role in the trend of miniaturized and refined products.

The improvement of waterproof performance is crucial to attract consumers and increase the attractiveness of the product and the degree of purchase.

Next, we will analyze in detail the international common waterproof grade of the waterproof connectors andtheirs needs in different products.

International waterproof rating of waterproof connectors:

The international waterproof rating is usually defined by the IP (Ingress Protection) standard, followed by two numbers, which indicate the dust protection rating and waterproof rating respectively. Here, we mainly focus on the waterproof rating.

IPX0 (0 rating, unprotected): Without any special protective measures, the connector is not protected against water and moisture and is susceptible to liquids.

1. IPX1 (1 rating, anti-vertical drip): The connector can resist dripping water in the vertical direction, but it cannot prevent liquid intrusion in other ways.
2. IPX2 (2 rating, anti-slanting drip): The connector is also protective against dripping water when it is tilted at 15 degrees, but it does not apply to water flow in the horizontal direction.
3. IPX3 (Class 3, splash-proof): The connector is protected against splashing water when tilted at 60 degrees.
4. IPX4 (4 rating, splashproof): The connector can withstand splashing water at any angle and is suitable for mild waterproofing needs.
5. IPX5 (5 rating, waterproof spray): the connector can resist water sprayed from any direction, suitable for some outdoor environments.
6. IPX6 (6 rating, strong spray): the connector can withstand strong water jets, suitable for more stringent waterproof needs.
7. IPX7 (7 ratings, anti-submergence): The connector can be immersed in 1 meter of water for 30 minutes without being affected, suitable for underwater equipment.
8. IPX8 (8 rating, submersible): The connector is capable of being fully submerged in 1.5 metres of water for half an hour without repercussions and is suitable for deep water equipment.
9. IPX9 (9 ratings, anti-temperature,,e and high-pressure spray): The connector can be subjected to 10kPa high-pressure water spray under high-temperature conditions below 80 degrees without being affected, applicable to extreme environments.

Different levels of waterproofing for product requirements

Different types of electronic products require different levels of waterproofing, depending on the environment and purpose of the product. For example:

1.  Waterproof phone watches usually require a waterproof rating of at least IPX7 or higher to keep them safe from rain or sweat during outdoor activities.
2.  Waterproof headphones may need IPX5 or IPX6 to ensure that they still work well in wet conditions, such as sweat protection during sports.
3.  Waterproof bracelets usually require IPX7 or IPX8 as they may be used in water activities such as swimming.
4.  Mobile phones usually have relatively high waterproofing requirements and need at least IPX7 to cope with accidental water activation.

In conclusion, the different waterproof ratings of waterproof connectors cater to different products and ensure that electronic devices operate reliably in a variety of environments. These standards and tests ensure that consumers can trust the performance of their devices in wet environments and reflect the electronics industry's concern for product quality and safety.
