How to make the connector waterproof? How are waterproof ratings classified?

Connectors are one of the most important components in electronic equipment, but they are often used in harsh environments such as humidity, water and corrosion. Therefore, waterproof is one of the important factors to ensure the normal operation and prolong the service life of the connector. This article will introduce how to make the connector waterproof and the classification of waterproof grade. How do I make the connector waterproof? In order to make the connector waterproof, the following methods are usually used: 1. Sealing: The contact surface between the electrical connector, plug and socket in the connector and the outside world needs to be sealed. Materials such as O-rings or silicone are usually used to ensure sealing performance. 2. Moisture-proof: Adding moisture-proof agent inside the connector can effectively prevent water accumulation and moisture intrusion inside the connector. This effectively prevents damage to internal electrical connectors, plugs, and receptacles. 3. Anticorrosion: In order to prevent the internal components and shell of the connector from corroding in harsh environment, special treatment is often carried out on the surface of the connector, such as electroplating, painting, etc., to achieve the function of anticorrosion. 4. Reinforcement: In the shell structure design of the connector, strengthening the joint part between the connector and the wire can make the connector more durable and increase the waterproof ability. How is the waterproof grade divided? Waterproof grade refers to the highest level that the connector can achieve in terms of waterproof, that is, its waterproof performance. According to the standards of the International Electrotechnical Commission (IEC), the waterproof grade is divided into different grades, which are usually expressed by IP plus two digits. Wherein, the first digit represents the dustproof grade, and the second digit represents the waterproof grade, such as IP68, which represents the ability of dustproof and waterproof, and the waterproof performance is the highest. The following are some common waterproof grades: 1. IP65: can prevent the invasion of jet water, but can not prevent immersion. 2. IP67: can prevent the intrusion of immersion in water, but can not prevent prolonged immersion. 3. IP68: able to maintain waterproof performance in the case of long-term immersion. It should be noted that the waterproof rating only indicates that the connector has some waterproof performance, but it does not guarantee that it will be completely waterproof in all cases. Therefore, when using the connector, it is necessary to select and use it according to the actual situation.
