Plug, its waterproof performance can even reach a depth of thousands of meters.

But the current waterproof plug mainly uses the above disadvantages:

1. Ordinary waterproof plugs have a relatively simple structure and low cost, but the waterproof performance cannot be used underwater;

2. For waterproof plugs that can be used underwater, the internal sealing structure is generally complex and there are many sealing parts, which makes the assembly of this sealing plug more cumbersome and takes a long time to install;

3. Due to the large number of spare parts used for underwater plugs, and the processing accuracy of the spare parts is very good, the cost of the current waterproof plugs is very high, making the cost of underwater consumer electronics products high and difficult to popularize.

4. Compared with current waterproof sealing joints in terms of tensile strength, the cable will fall off from the joint under the action of 10kg force, which is very limited for some environments that require tensile resistance.
