Waterproof connectors, as the name suggests, are connectors that can be applied to environments with water and can ensure the normal use of internal mechanical and electrical properties of the connector under certain water pressure.

Today, we will briefly analyze the usage characteristics and performance of waterproof connectors. By focusing on the waterproof testing requirements of IP68 waterproof connectors, we believe that understanding this issue will be helpful for better understanding the selection of waterproof connectors.

Firstly, we need to recognize that IP68 waterproof connectors are widely used in our daily lives, such as LED street lights, water level recorders, remote water meters, water quality monitoring, navigation, lighthouses, cruise ships, industrial equipment, sprinkler trucks, etc. In addition, they can even provide safe and reliable connections in harsh environments.

The IP68 waterproof test we usually propose refers to ensuring that it works for 2 weeks at a water depth of 10 meters without water ingress; After being placed in a water depth of 100 meters and subjected to 12 hours of destructive testing, the product's good performance can still be maintained. This is the waterproof testing requirement for the so-called IP68 waterproof connector.

1、 Waterproof plug contact resistance. Contact resistance can be seen everywhere in the electrical performance applications of waterproof plugs, and a high-quality and durable waterproof plug meets the characteristics of low and stable contact resistance applications. The contact resistance range of waterproof plugs fluctuates greatly, ranging from a few milliohms to several tens of milliohms. The parameters depend on the actual performance and characteristics of the waterproof plug.

2、 Insulation resistance of waterproof plug: insulation resistance is also an important indicator of electrical performance of waterproof plug. Insulation resistance and contact resistance are two vaults of electrical performance of waterproof plug, and they Co-determination determine the resistance performance of waterproof plug. The specific function of insulation resistance is an important indicator to measure the insulation performance between the various contacts of waterproof plugs and between the contacts and the shell. Its value must comply with industry regulations, otherwise it will cause the waterproof plug to not function properly or not function perfectly. The insulation resistance range of waterproof plugs can range from hundreds of megaohms to thousands of megaohms, depending on the actual situation.

The main products of waterproof connectors include M2, M3, M4, M5, M6, M7, M8, M9, M10, M11, M12, T-type three-way wire, Y-type one drag 2-N medium card wire series waterproof wire, as well as other lighting accessories such as DC wire, terminal wire, plug, etc.

Waterproof connectors are widely used in LED lighting (such as light strips, panel lights, street lights, display screens, lighting, floodlights, plant lights, mining lights, tunnel lights, etc.), as well as in communication, automation, new energy, marine electronics, unmanned aerial vehicles, and automotive applications.
