Waterproofing of mobile phones has become an indispensable feature in people's lives. The rapid development of waterproofing technology makes underwater photography in swimming pools no longer a dream. S8 和 note8 、 LG G6 、 iPhone8&iPhone8P 也达到 IP68 防水。 Last year, Samsung S8 and note8 , LG G6 , iPhone8 & iPhone8P also reached IP68 waterproof. Under the leadership of the giants, waterproof technology will not only be widely used in mobile phones, but also have a huge market in the watch industry, especially the smart watch industry. With the rise of smart watches and children's smart watches, waterproof technology has become a standard feature of many smart watches. Like mobile phones, it has become a difficult problem that must be broken on the development of the industry. 3C 产品及汽车、医疗领域等也将迎来巨大的市场规模。 Waterproof technology will also usher in a huge market scale in 3C products and in the automotive and medical fields.
So how does the phone achieve waterproof effect? There are two principles: one is waterproof structure. By reducing the splicing of the fuselage, the pressure on sealing the exposed gap of the fuselage is reduced, and the waterproof rubber strip and sealing ring are used as backup protection means, so that the fuselage The overall waterproof ability is enhanced. For the multiple joints of the mobile phone, the connection is also maintained with a similar waterproof rubber strip material, so that the all-round sealing structure can block the intrusion of dust and liquid. However, the method of structural sealing also has a very big disadvantage, that is, the earphone holes, charging holes and other components that cannot be exposed can only be waterproofed by rubber plugs, and cannot be sealed. Another problem is that if the mobile phone is dropped or bumped when using it, the structural parts of the mobile phone may be deformed, the sealing structure will be damaged, and the waterproof performance may be invalidated. Therefore, mobile phone manufacturers generally add a second waterproof method. The second waterproof method is nano-waterproof.
iphone 7 & iPhone 7 Plus 取消了耳机孔，采用 lighting 转换器，少了耳机孔，从防水角度上来说，也是少了一个易进水的部位。 Let's talk about the first waterproof technology structure today. Many people know that the iPhone 7 & iPhone 7 Plus has eliminated the headphone jack, adopted a lighting converter, and reduced the headphone jack. From the perspective of waterproofing, it is also a little easier. Ingress of water.

The easy-to-water parts are all sealed with silicone rings and also sealed in the following positions:

From this we can see the importance of the sealing ring in the field of waterproof and dustproof of mobile phones, so why do many mobile phone manufacturers choose a silicone material sealing ring to waterproof it? 硅橡胶 O 型圈 具有温度适应广、密封性、绝缘性、介电性、环保性等良好的特性，同时耐高低温，受外界环境干扰少，因此是最为理想的防水，密封材料，防水圈，硅胶防水圈的邵氏硬度有 20 至 90 度。 Because silicone rubber O -rings have the characteristics of wide temperature adaptation, tightness, insulation, dielectricity, environmental protection, etc., meanwhile, they are resistant to high and low temperatures, and are less affected by the external environment. Therefore, they are the most ideal waterproof, sealing materials, waterproof The silicone rubber waterproof ring has a Shore hardness of 20 to 90 degrees. Silicone seals are used on the seal of smart phones. Someone said a long time ago that the biggest challenge in waterproofing is that it can't make the crystal permanently fixed on the frame. However, the silicone material has achieved this effect. At present, the trend of mobile phone frames is mainly used High softness silicone rubber is processed and manufactured with high precision. No gap phenomenon can occur after assembly, and a certain effect can be achieved by adhesive bonding. Therefore, the silicone seal ring plays an important role in the field of mobile phone waterproof!
