Waterproof connector is a connector that can be applied to the environment with water and can ensure the normal use of the internal mechanical and electrical properties of the connector under certain water pressure

1.        The demand for their own products, many manufacturers in the choice of connectors, regardless of three seven twenty-one to choose waterproof connectors, after all, the performance of waterproof connectors is superior than the performance of ordinary connectors, the scope of application is more extensive, but some products do not need to use waterproof products, so the choice of waterproof connectors will cause a great increase in cost, which is not worth it.

2.        It is necessary to consider the shape of the choice of the connector, waterproof connectors have their own various shapes, manufacturers need to consider the size, weight, color, material requirements, shape and so on of the connector when choosing.

3.        Working temperature is also an important factor affecting the choice of connectors, general connectors use insulation materials and metal materials, once used in a high temperature environment, will destroy the insulation material on the surface of the connector, will also have an impact on the metal, so this factor must be considered when choosing.

4.        The use of environmental pressure, some high-altitude air thin environment when using waterproof connectors need to pay attention to its impact. Special attention should be paid to the fact that when using unsealed connectors at height, they must be used in derating.
