As an important connecting component between electronic devices, the sealing and waterproof levels of rectangular connectors are particularly important when used outdoors or in harsh conditions. In order to ensure the stable operation of connectors in various extreme environments, designers need to carefully create their sealing and waterproof performance from multiple aspects such as material selection, structural design, and manufacturing process.
In terms of material selection, rectangular connectors usually use corrosion-resistant, wear-resistant and elastic materials such as stainless steel, aluminum alloy, and special synthetic rubber. These materials can not only effectively resist the erosion of dust, moisture, etc. in the external environment, but also maintain stable sealing performance during the connector plugging and unplugging process. In particular, the material selection and manufacturing process of rubber sealing rings have a crucial impact on waterproof performance.
In terms of structural design, rectangular connectors use a variety of sealing technologies. For example, a tight rubber sealing ring is designed at the connector interface, and the waterproof function is achieved by compressing the sealing ring. In addition, some high-end connectors also use a multi-layer sealing structure, that is, an additional sealing layer is added inside the connector shell to further improve the waterproof level. At the same time, the shell design of the connector is also very important. Usually, a waterproof shell is used. Through special processing, a dense waterproof layer is formed on the surface of the shell to effectively prevent water penetration.
The manufacturing process also has an important impact on the sealing and waterproof level of the rectangular connector. During the production process, the dimensional accuracy and assembly tolerance of each component need to be strictly controlled to ensure the perfect fit between the sealing ring and the connector interface. In addition, the connector needs to be strictly tested for sealing performance, such as immersion test and pressure test, to ensure that its waterproof level meets the design requirements.
The waterproof level of the rectangular connector is usually divided according to the IP (Ingress Protection) protection level standard. For example, a connector with an IP67 rating means that its dustproof level has reached level 6, that is, it completely prevents foreign objects and dust from intruding; at the same time, its waterproof level has reached level 7, that is, it can be immersed in water of a certain depth for a period of time without water ingress. Such a waterproof level can already meet the use requirements of most outdoor or harsh conditions.
In summary, the design of the sealing and waterproof level of the rectangular connector is a complex and delicate process, which requires comprehensive consideration from multiple aspects such as material selection, structural design and manufacturing process. Only in this way can we ensure the stable operation of the connector in various extreme environments and provide strong guarantee for the reliable connection of electronic equipment.
