cautions for use

Waterproof junction box is a device used to protect wire joints and avoid damage to electrical equipment caused by water, dust and other external factors. It is usually made of special materials, such as ABS, PC and other high-strength, fireproof, waterproof, anti-corrosion, anti-corrosion plastic or metal. Used in outdoor, humid and rainy environments, it can effectively protect electrical equipment and prevent peace of mind accidents. This article will introduce the role of waterproof junction box, types and precautions for use.

Function

The main role of the waterproof junction box is to protect the wire joints and connectors from the external environment. In the outdoor, humid, rainy environment when using wires, will encounter water, dust and other external factors on the wires caused by damage to the situation. In this case, without the protection of waterproof junction box, the wire will be easy to short-circuit, power failure, etc., causing damage to the equipment, and even cause fire and other dangers.

Another function of the waterproof junction box is to enhance the firmness of the wire connector. Wire connectors usually have two or more wires connected, if not protected, the connection is easy to loose because the direction of the force is not consistent, resulting in poor contact and other failures. The use of waterproof junction boxes can enhance the degree of fixation of wire connectors, ensuring a firm and reassuring connection.

Types

According to the use and structure, waterproof junction box can be divided into various types:

Vertical waterproof junction box: the structure of the form of cubic or rectangular, mainly used for a single or a small number of wire connections. Usually fixed to the wall or column.

Horizontal waterproof junction box: the structure of the form of a long strip or rectangular, mainly for the connection of multiple wires, can be installed on the wall or the top and other locations.

Round waterproof junction box: the structure form is round or oval, mainly used for wires in the round or curve surface connection. For example, it is installed on street lights or surveillance cameras.

Primary molding waterproof junction box: the structure is molded as a whole, the wires are connected to each other inside the connector, which is suitable for the more severe environmental conditions.

Explosion-proof waterproof junction box: suitable for use in coal mines and other explosive hazardous places, with isolation, explosion-proof, waterproof and other characteristics.

Solar waterproof junction box: with UV resistance, high temperature resistance, waterproof and other characteristics, suitable for solar photovoltaic system connection.

Other types: according to different needs, there are some special waterproof junction box, such as: lightning waterproof junction box, anti-mosquito waterproof junction box.

Precautions for use

1. Select the appropriate waterproof junction box: when choosing a waterproof junction box, you need to consider the use of the environment and the number of wire connections and other factors, select the appropriate type of waterproof junction box and specifications.

2. Installation location: the location of the waterproof junction box needs to avoid rainstorms, flooding and other situations to ensure that the connector is not flooded.

3. Installation: When installing the waterproof junction box, according to the type of junction box and the use of the environment, choose the appropriate installation method to ensure that the installation is firm and stable.

4. Wiring method: correct wiring is an important factor to ensure that the connector works well. Should follow the standard wiring diagram inside the junction box wire connection diagram to ensure that the wiring is correct.

5. Maintenance: Regularly check the sealing of the waterproof junction box to ensure waterproof performance and peace of mind connector.

In short, the waterproof junction box is an important electrical connection device, in the outdoor, humid and other environments when using the wire, can protect the wire from external factors, enhance the firmness of the wire connection and peace of mind. When purchasing and using waterproof junction box, you need to pay attention to choosing the right type and specification, the correct installation method and wiring, and you need to check and maintain it regularly. This can effectively protect electrical equipment and improve the peace of mind and reliability of wire connections.
