Development background of waterproof connector

With the development of science and technology, the application of electrical plug is more and more extensive. With the emergence of underwater consumer electronic products, we urgently need electronic plug to have waterproof function, and waterproof depth can reach at least 100 meters, but at the same time the structure is simple, easy to assemble, and the cost is also comparable. Low.

After years of development, there are many kinds of 2 Pin Waterproof Cable Connector, such as ordinary 2 Pin Waterproof Cable Connector, and their structure is relatively simple, waterproof performance can only reach IP65; of course, waterproof joints with excellent waterproof performance can reach IP67 or more, which can be used in deep-sea waterproof joints, and their waterproof performance can even reach the depth of thousands of meters. .

But the current PG Cable Gland mainly use the above disadvantages.

1. Ordinary waterproof PG Cable Gland has simple structure and low cost, but its waterproof performance can not be used underwater.
2. For waterproof PG Cable Gland that can be used underwater, the general internal sealing structure is complex and there are many sealing parts, which makes assembling this sealing plug more complicated and takes longer installation time.
3. Because there are many spare parts in the underwater plug, and the precision of the spare parts is very good, the cost of the waterproof joint is very good, which makes the cost of the underwater consumer electronic products remain high and difficult to popularize.
4. Comparing the tensile strength of the waterproof sealing joint at present, the cable will fall off the joint under the action of 10 kg force, which is very limited for some places where tensile force is needed.

Product structure

In order to solve the problems of complicated structure and high cost of underwater plug in the prior art, the invention provides a waterproof PG Cable Gland.

A novel waterproof connector device comprises a socket, a plug and an external cable. The plug comprises a plug cavity and a plug rubber core. The plug rubber core is located in the plug cavity and fills the inner part of the plug cavity with plug filling glue to achieve sealing and waterproof. The outer cable is connected with the plug rubber core and the plug rubber core is connected with the plug rubber core. The external cable extends from the plug cavity; the socket includes the socket cavity and the socket rubber core, which is located in the socket cavity and is filled with glue through the socket filling to achieve sealing and waterproof; when the socket is installed with the plug, the socket rubber core is located in the socket cavity; and when the socket is installed with the plug, the socket rubber core is sealed and waterproof. The butt joint position of the plug is waterproof and sealed.

The 2 Pin Waterproof Cable Connector has higher cost performance. In fact, waterproof joints and ordinary connectors, the price is not much higher, so that is to say, we used the same price as ordinary joints, but bought a product with higher safety performance, so the cost-effectiveness has been greatly improved. In the pursuit of cost-effective, we should consider that this product is much better than the ordinary connector.
