Waterproof Plug and Socket Connector

Waterproof plug and socket connector is an important component of wiring harness. Its mechanical life, contact resistance and insulation resistance are important. It can be divided into different types by the assembly method, material and electrical properties.

Metal series are high quality at competitive price at signal plugs, aviation series are for power/Signal plug and PVC series is for general purpose.


Waterproof plug and socket connectors are used in a car wiring harness to protect wires from being exposed to the wet environment. Various environmental parameters can affect the waterproof level of these connectors, so it is important to select the right ones for your application. This article will discuss some of the main factors to consider when selecting a waterproof plug and socket connector.

The most important factor to consider when choosing a waterproof plug and socket connector is the material. There are a few different options to choose from, including metal and plastic. Both have their own advantages and disadvantages. Metal is more durable and has a better performance than plastic, but it can be more expensive. Plastic, on the other hand, is more economical and has a good sealing function.

In addition to the material of the waterproof plug and socket connector, it is also important to consider the design. For example, the insertion depth of the waterproof connector should be carefully considered to ensure that it does not damage the wires inside. In addition, the insertion speed should be appropriate for the application. The waterproof connector should also be easy to dismantle and reassemble. Finally, it should be resistant to vibration and shock. For these reasons, you should choose a waterproof plug and socket connector with a solid mounting plate.


Waterproof connectors must be designed with a variety of factors in mind. Some of these include the assembly method, materials, electrical properties, and the environment in which they will be used. There are different waterproof plug and socket connectors that can be selected depending on these considerations. For example, there are Nylon over mold series, aviation series, and metal series of waterproof plug and socket connectors.

The design of a waterproof connector may also be considered in terms of its mating style, gender, and internal parts. For example, some waterproof plug and socket connectors are male polarized while others are female polarized. This can help prevent wrong insertion of a power wire waterproof plug and socket connector into the connector which could lead to a short circuit or electric shock.

There are also hybrid waterproof plug and socket connectors that can carry both power and signal circuits. These types of waterproof connectors can be useful in situations where space is limited or to mitigate potential wiring issues.

The internal parts of a waterproof plug and socket connector can be made from a number of materials including brass, copper, and nickel. The contacts inside a waterproof plug and socket connector can also be gold plated which can improve the transmission of extra-low voltage signals. The shell of a waterproof plug and socket connector can also have a variety of coatings such as black oxide or zinc yellow plating to provide a more durable and corrosion-resistant finish.

Waterproof Level

Waterproof plug and socket connectors can withstand a wide range of working environments. They waterproof connector manufacturer are also rated according to their level of protection against dust and water. This is represented by the IP code. The higher the number, the more water and dust the connector can withstand.

A waterproof connector must have a seal that prevents water from entering the internal circuit. It must also be resistant to corrosion. In addition, it should be able to withstand high temperatures. This is why it is important to choose the right type of waterproof connector for your application.

To ensure that a waterproof connector meets these requirements, the gap between the multi-strand copper wires in the core and the outer shell of the cable must be large enough. In addition, the inner diameter of the connecting hole, the outer diameter of the wire insulation and the inner diameter of the sealing plug or blind plug should be closely matched.

Positronic offers a variety of waterproof and hermetic connectors that meet these requirements. These include the Cliffcon 68 Series, which is ideal for rugged and waterproof applications. It has a panel mount and is compatible with a range of mounting sizes. It also has gold-plated contacts and is suitable for use in high-current applications. It is also easy to assemble.


Waterproof plug and socket connectors are used in electrical applications where water or dust may enter the cable-to-connector interface. They are often specified in environments that will experience exposure to moisture or water for a prolonged period of time – including submersion – or where the connections will be subjected to impact forces from vibrations and external shocks.

These connectors are typically constructed from durable materials and feature a seal that provides waterproof protection. They are also designed to withstand challenging environmental conditions that may include temperature variations, mechanical stress, and vibrations. These features contribute to the overall strength and reliability of the design, which is often indicated by an IP rating that indicates the level of dust or water resistance.

Plug and socket connectors with this rating can be used in a variety of applications, including industrial cable-to-cable connections, outdoor power tools and equipment, marine electronics, medical instruments, and outdoor lighting projects. These connectors are also frequently found in military vehicles like tanks and aircrafts, as well as in marine applications such as submarine-launched missiles.

In addition to providing waterproof sealing, these connectors typically offer a robust locking mechanism that prevents accidental uncoupling from vibrations or pulling forces. They are generally available in a wide range of styles, lengths, assemblies and packing options to meet the needs of specific applications.
