Wire connection operation

1. Strip the cable

Use wire strippers to strip the insulation skin of the wires that need to be connected to an appropriate length, generally about 1-1.5 cm. When stripping the wire, be careful not to damage the internal metal wire to ensure the integrity and conductivity of the wire.

2. Insert the connector

Insert the stripped wires into the corresponding interfaces of the waterproof three-way wire connectors. Typically, there are markers on the connector indicating different line connection locations, such as live wire (L), neutral wire (N) and ground wire (E). Insert the wire exactly as marked, ensuring that the wire is inserted at a moderate depth and is in close contact with the metal contacts inside the connector.

3. Secure the connection

After the cable is inserted into the connector, use a screwdriver to tighten the screws on the connector to secure the cable in the connector. The tightening strength of the screw should be moderate, too loose may lead to poor wire contact, resulting in heating or sparks and other problems; Too tight may damage the metal parts of the wires or connectors.

Ensure water resistance

Step 1 Apply waterproof glue

After the wire is connected to the connector, apply an appropriate amount of waterproof adhesive to the connector interface. The waterproof glue should be evenly covered around the interface to form a sealing layer to prevent water from penetrating into the interface. Be careful not to apply waterproof glue to the metal part of the wire, so as not to affect the electrical conductivity.

2. Install a waterproof cover

Part of the waterproof three-way wire connector is equipped with a special waterproof housing. Install the waterproof housing properly on the connector, ensuring that the housing fits the connector tightly without gaps. The installation method of the shell may vary according to the model. Generally, the shell is fixed by fasteners or screws, and the operation is carried out according to the requirements of the product manual.

Post-installation inspection

1. Check appearance

After the installation is complete, carefully check the connector appearance to ensure that the waterproof adhesive is evenly applied, there are no bubbles or cracks, and the waterproof shell is securely installed. At the same time, check whether there are exposed metal wires at the connecting parts of the wires. If there are any, re-insulate them.

2. Electrical performance test

Before power is restored, test the connected circuit using an electrical test tool such as a multimeter. Check whether the resistance between the live wire and the neutral wire, between the live wire and the ground wire, and between the neutral wire and the ground wire is normal, and ensure that no short circuit or open circuit occurs. You can also test whether the voltage is stable and meets the requirements of irrigation equipment.

Waterproof three-way wire connector long-term maintenance need to pay attention to what?

Periodic inspection

1. Check the frequency

It is recommended to regularly check the waterproof three-way wire connector every 1-2 months. In the case of frequent use or harsh environmental conditions during the irrigation season, the number of inspections can be appropriately increased.

2. Check the appearance

Check whether the appearance of the connector is damaged, deformed, and faded. Check whether the waterproof glue has fallen off or cracked, and whether the waterproof shell is broken or loose. If the problem is found, it should be repaired or replaced in time. At the same time, check whether there are weeds and debris accumulation around the connector, if so, it should be cleaned up in time to keep the surrounding environment clean.

Clean surface dirt and impurities

1. Harm of dirt impurities

In the agricultural irrigation environment, the connector surface is easy to accumulate dirt, dirt, pesticide residues and other dirt impurities. These dirt may affect the heat dissipation performance of the connector, resulting in an increase in its internal temperature and accelerated component aging. In addition, conductive substances in dirt can also cause electrical failures such as leakage or short circuit.

2. Cleaning methods

Use a clean, damp cloth to gently wipe the connector surface to remove dirt and impurities. For difficult to remove stains, you can use a small amount of neutral cleaning agent to clean, but to avoid cleaning agents into the interior of the connector. After cleaning, dry with a dry cloth or air dry to ensure that the connector surface is dry.

Check the waterproof seal

1. Tightness test method

Regularly test the waterproof sealing of the waterproof three-way wire connector. A simple water spray test can be used to put the connector in normal working condition and spray it with a sprayer to simulate the splash situation of rain or irrigation water. After spraying water, observe whether there is water inside the connector. If water beads or water stains are found, it indicates that there is a problem with the waterproof seal.

2. Handle sealing problems

If you find that there is a problem with the waterproof seal, you should first check whether the waterproof glue is damaged or fallen off, if so, reapply the waterproof glue. If the waterproof shell is not tightly sealed, check whether the buckle or screw of the shell is loose and tighten it in time. If the shell or sealing part is seriously damaged, replace the waterproof shell or sealing part in time.

Check electrical connections

1. Check the connection reliability

Periodically check whether the wire is firmly connected to the connector. Gently pull the wire to see if it is loose. If the cable is loose, tighten the screws on the connector in time to ensure that the cable is in close contact with the metal contact of the connector.

2. Electrical performance monitoring
