Waterproof Submersible Electrical Connectors
Electrical wiring can easily be damaged by water if not properly protected. That’s why waterproof connectors are so important in many different types of applications, especially for outdoor lighting and marine equipment.
Waterproof connectors come in all shapes and sizes. Some are meant to connect individual wires while others are designed for entire electrical harnesses. They can also be rated for dust, temperature resistance and corrosion protection.
Sealing
Whether used in robotics, deep-submarine applications, or marine oil and gas operations, electrical connectors must function efficiently under the sea. Wet-mate connectors like the ELITE series from AMETEK are designed and fabricated to maintain electrical integrity while submerged in liquids for extended periods of time. They use a combination of hermetic seals and high-strength mechanical designs to guarantee power transfer while keeping water out of the electrical contacts.
However, there’s one element that’s even more critical to the success of underwater electrical connectors: pressure. As equipment gets deeper under the surface, it can encounter massive pressures – sometimes upward of 10,000 pounds per square inch. This amount of force can easily compromise the boundaries of a connector and cause service interruptions or system failure, jeopardizing operation and potentially putting human lives at risk.
To protect against this, waterproof electrical connectors have an ingenious sealing mechanism that uses a locking sleeve molded into a rubber body to create a water-resistant seal around the glass-reinforced male and female connector ends. This prevents water from leaking into the connector while still allowing it to be locked and unlocked. These waterproof connectors also feature a tactile click and audible “click” when properly mated, reducing installation and maintenance time and effort. They are available in various sizes, pin configurations, and contact materials to accommodate the needs of a wide range of applications and equipment.
Boxes
Electrical connectors are used in a wide variety of applications and must be safe to use underwater. They must also be able to withstand a specified amount of pressure. Using the wrong type of connector could lead to corrosion and potentially dangerous situations. Waterproof connectors are often characterized by their IP rating. This is determined by the two digit code that shows how well they resist both solid dust particles and immersion in liquids.
The mating mechanisms of waterproof connectors must be easy to use in a wet environment, especially if they are mated and disconnected while submerged. Secure locking mechanisms can prevent unintended disconnections. In addition, the voltage and current ratings of a connector must match those of the equipment and cables that it is designed to connect.
Typically, wet-mate waterproof connectors are made from materials such as polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), and polyethylene. They are moisture-resistant and can withstand high amounts of pressure. iCONN’s wet-mate connectors feature a patented design that uses niobium waterproof submersible electrical connectors contacts to create an insulating film when mated. This prevents electrical connectivity when the contacts are exposed to water and eliminates the risk of corrosion.
iCONN’s wet-mate waterproof connectors are ideal for underwater LED lighting projects, marine equipment, and other projects that require a reliable connection in wet environments. Our patented designs also reduce the cost and lead time compared to traditional underwater cable connectors.
Tape
Electrical connections are vulnerable to moisture and water ingress. If the connections are not properly sealed, it can disrupt important signals or corrode the contacts. To prevent this, it is important to use the proper tools and materials for waterproofing. This includes using waterproof electrical tape, silicone sealant and epoxy resin to ensure the proper protection of the connectors in wet environments. These products are available at hardware stores and automotive or electronic suppliers. It is also important to follow safety regulations when working with electricity and always seek the assistance of a professional electrician.
Often used in outdoor systems and marine technology, waterproof connectors form a tight seal to resist high humidity and submersion. They are also commonly found in industrial applications, including data communication installations, transportation equipment and military equipment.
There are several types of waterproof electrical connectors on the market, from crimp-style to solderable. Each has its own advantages. For example, crimp-style waterproof wire connectors are ideal for confined spaces and can be pressed to create an electrically-insulated connection. Solderable waterproof wire connectors, on the other hand, do not require crimping and can be secured by applying heat with a heat gun. Another benefit of these connectors is that they can be repositioned after installation, which is helpful for installers working in a confined space.
Sealant
Electrical connectors play a critical role in many electronic and electrical systems, allowing for the connection and disconnection of wires and cables. In environments where the equipment is exposed to water or moisture, it’s crucial that these connectors are adequately protected to avoid damage and failure. Fortunately, there are a few easy ways to make electrical connectors waterproof, including using hermetic connectors, connection boxes and suitable waterproof tape or sealant.
The most reliable way to make a connector waterproof is to use hermetic waterproof 3 way wire connector connectors, which are designed to withstand the elements. These waterproof electrical connectors feature an outer shell that creates a tight seal around the inner parts of the connector, preventing moisture from entering. This is particularly useful for applications where the connectors will be used in high-moisture environments like marine settings and outdoor lighting.
Another great option is to use waterproof wire nut connectors, which have two hot melt waterproof adhesive rings in each butt connector. These rings prevent moisture from entering the connectors, and they can be used in a variety of applications including marine navigation, outdoor lighting and security systems.
Finally, there are waterproof molded connectors that are injection-molded in a flexible material such as neoprene or polyurethane. These waterproof electrical connectors can be mated and unmated underwater without risk of damage or corrosion. They can also be used in harsh environments like marine electronics, traffic control systems and off-road vehicles.
