Waterproof telephone introduction

From the essence of the definition, waterproof telephones belong to the category of special telephones in fixed telephones.

According to the use environment and strength, it can be divided into two categories: consumer-grade waterproof telephones and industrial-grade waterproof telephones. Military users' field-operated waterproof telephones are not included in this introduction because of their use and confidentiality.

Before specifically analyzing the two major categories of telephones, you first need to understand the level, basis, and description of the waterproof class.

The waterproof performance of the telephone is defined according to the IP protection class. The basis is the "GB4208-2008 enclosure protection grade" specific description table attached

Consumer Consumer Phones

In daily life, the most common application scenario is bathroom and bathroom

Use units are mostly for families and hotels

In general, we can only think that the phone has a waterproof function.

Most domestic manufacturers do not label the corresponding IP waterproof code. From the sales of the top 100 products on the two major e-commerce websites, we did not understand the waterproof rating of the relevant products. Keywords used: bathroom telephones, bathroom telephones, household waterproof telephones. According to our understanding, from the shell waterproof performance, this type of product is strictly speaking, not waterproof. At the same time, we cannot determine whether we have done moisture treatment.

There is also an application scenario that can be classified as a consumer product. In general, public telephones include outdoor telephones on campus, special telephones for prison systems, and telephones for help in scenic spots. This product does not require a high level of protection, generally IP54.

Industrial waterproof phone

We can analyze the waterproof performance of a waterproof telephone from three aspects of design, material and process.

First of all, the design, in the field of waterproofing, is generally divided into two kinds of waterproof, one is structural waterproof, the other is technical waterproof.

Structural waterproofing, as the name implies, means that the ID engineer team designed a waterproof telephone with a certain waterproof performance during the design phase by virtue of its understanding of the waterproof structure. How to isolate liquids and moisture outside the telephone is crucial. In China, there are already quite outstanding designs, including brands such as Sanzhou, Kunlun and Laowo.

Materials and processes, materials, please refer to our previous article "Industrial Telephone Science Popularization"

The process can only be simple, using waterproof coating. With the corresponding materials, the telephone can be well protected. At home, mainstream manufacturers have gradually evolved from IP54 to IP65 or even IP66-68 protection levels.

Note: The corresponding degree of protection for any waterproof phone is only for the unopened case. The degree of protection is invalidated after any disassembly occurs. Therefore, we strongly recommend that the integrator and the weak engineering company inform the use environment and the required external interfaces (RJ11/RJ45/SC) during the subscription phase.

Protection level dummy

Due to market reasons, various channels compete fiercely. Especially in the field of tendering and bidding, we have found that some integrators use IP54 waterproof telephones to act as IP65 to bid, and some small brands use their own products with IP65 or higher protection levels. For such national conditions including 100-yuan products, we deeply understand that life is not easy. However, we sincerely recommend that such products should be used at most in the industrial basic protection field and must not be used in such situations as defense communications, tunnels, and tube corridors.

price

In China's energy industry, especially in the three major industries of petroleum, petrochemical, power, and coal, the demand for this product is relatively high. As early as in the early 1980s, foreign brands of waterproof telephones were introduced, but the prices were staggeringly high. For example, in the US G-brand waterproof telephones purchased by Ningbo Energy Group-Ningbo Beilun Power Plant, in 1994, the procurement unit price was 650 US dollars/set (compared with the then exchange rate, more than 6,000 yuan/set). The price of this model product in 2017 is still up to 550 US dollars (US Wal-Mart price) and does not include domestic taxes and shipping costs.

So you can imagine, today, you can buy in 1688 or Taobao platform hundred-level product reliability? You can responsibly tell you that the hundred-dollar products in the materials, processes, PCB, SOC and other aspects of cutting corners are outrageous, according to the random purchase of counterfeit HAT86 model telephones, waterproof and dustproof grades are not up to standard.
