What is a Waterproof Junction Box?

The waterproof junction box is one of the electrical accessories. It can be used both inside and outside the house to keep rain and dust out of the house, as well as successfully keeping the circuit inside the box and electronic equipment out of the water.

The decorating wire is used as a transition because it passes through the wire tube and is utilized in the wire joint section (such as when the line is longer or where the wire tube meets the corner). It is attached to the wire tube. To protect and link the wires inside the conduit, the wires are joined at the junction box.

To install the terminal block and as a connecting device, thermocouple and thermal resistance junction boxes are employed. It protects the temperature sensing element from the external atmosphere’s corrosion while also connecting the external conductor to the termination well.

It is dependent on the temperature object that has been measured, as well as the site’s environmental circumstances and requirements. There are splash-proof, waterproof, and plug-in junction boxes in addition to standard junction boxes.

How to install the waterproof junction box?

The waterproof junction box comes with a bottom plate that may be used to mount customer monitoring equipment and is secured with screws.

When it comes to the wire connection to the junction box, it’s critical to ensure waterproof performance by using waterproof connections and making sure the position of the entrance is waterproof. If you require waterproof connector accessories, please contact us and we will give the appropriate size.

How to choose a waterproof junction box that meets the IP63-IP68 waterproof rating?

There are two types of waterproof junction boxes: plastic and aluminum. The application and performance of each is different. Let’s take a closer look at the differences.

• IP63 – From the 60 degree corner to the shell, rain or water has no effect.
• IP64 – Splashes of liquid from any direction have no effect on the shell.
• IP65 – Nothing terrible will happen when washing with water.
• IP66 – It can be used in a cabin setting.
• IP67 – Intense water resistance in a short period of time (1m).
• IP68 – Immersion in water over an extended period of time under a specific pressure, such as deep water cable wiring.

The dust-proof, waterproof, anti-corrosion, insulation, and impact-resistant plastic waterproof junction box is constructed of ABS, PC, or another plastic material with the following properties: dust-proof, waterproof, anti-corrosion, insulation, and impact resistance.

Multiple internal installation points provide optimum convenience for the installation of rails, circuit boards, power modules, and expansion boards, and the upper cover fastening screws are designed to prevent coming off and avoid loosing screws.

Some manufacturers choose for a PC upper cover that is transparent. Petrochemical facilities, ports, sewage treatment plants, electroplating plants, gardens, residential illumination, rail transit, and other applications can all benefit from various sizes and specifications.

Die-casting silicon aluminum alloy is used to create the cast aluminum waterproof junction box. The cast aluminum waterproof box has a high level of environmental adaptability thanks to the application of spraying surface treatment technology. Cast aluminum junction boxes, when compared to identical plastic junction boxes, feature heat dissipation, anti-static, and flame retardant properties due to the metal’s properties. The working temperature range of -40° to 120° can better adjust to the high and low temperatures in which the equipment is installed.

The The majority of goods come with metal hanging feet to make mounting the equipment on the wall easier. Threads for component installation are built into the mounting boss at the bottom. The electrical equipment shell can also be grounded using the interior mounting points.

The customization process

1.We recommend the right size based on the client’s electrical equipment; if the customer wants to use the waterproof junction box outside and monitor the situation from the outside, the transparent cover is an option.

2.If you want to keep the box outside for a long period without it fading, use a PC material that meets flame retardant, high temperature resistant, and waterproof IP67 criteria. We are happy to accept special requests.

3.After you’ve confirmed the box size and appearance, we’ll open the waterproof junction box, make sure the size and location of the hole is clear, and prepare drawings according to the customer’s specifications for their approval, before sending samples to the customers for confirmation. We use a CNC opening machine, which has a lower mistake rate since the opening is more exact thanks to the inspection of the opening sample.

4.We will gladly mail to clients for each process step. For example, we might provide a sample to the customer and discuss the details of internal installation with them. We are concerned about what elements can affect the signal of the junction box, and we will replace it after a successful discussion.

5.We provide a separate inner case to reduce collision and protect the waterproof junction box and accessories during shipment. The shipping mark is labeled on each box to show the customer’s quantity and accessories in each box, making it easy to check. Our never-ending objective is to provide high-quality products on time to your hands.

6.We will promptly follow up on logistics information and maintain close touch with the customer, and we can also supply installation connectors and accessories for the customer. To save time, you will find it beneficial to use the junction box right away.
