How To Connect Metal Cable Waterproof Connector?

Many places use Nylon Cable Gland to connect. When connecting, how to connect better? This is a question that many friends are very concerned about. After all, if the connection is wrong, it may cause the entire line to be unable to be used normally.

1. Connector connection method

At present, the more common cable connectors can be mainly divided into "cross" connection method, "one" connection method and "D" connection method when connecting.

When connecting, you should ensure that the connector is tightly wrapped and the surface is smooth and thorn-free. Before disconnecting the wire head, you can use wire cutters to press it gently, then wrap it to the exit, and gently swing it left and right, and the wire head can be disconnected at the connector very well.

The connector should be dry. In order to ensure the insulation effect, you can use two layers of insulating black cloth to wrap it, and then use two layers of plastic tape to wrap it, and then use two or three layers of insulating self-adhesive tape to wrap it outside, and finally wrap it with two layers of plastic tape.

How to connect the waterproof connector of metal cable?

There may be many safety hazards when using plastic glue directly. After a long time of use, the plastic tape is prone to raw glue dislocation and glue opening. Especially when the load of the electrical appliance is heavy, the temperature of the joint connection part rises, and the plastic tape is easily heated and melted and shrunk.

When the joints are pressed against each other in the junction box, if there are burrs on the surface of the joint, it is easy to puncture the plastic tape, which may cause the circuit to burn out. The consequences of these hidden dangers are very serious.

If insulating black tape is used when connecting, the above situation can be well prevented. This is because the circuit has strong strength and high flexibility. It can wrap the joint position for a long time. It will not be affected by time and temperature, and it also has good flame retardancy.

After wrapping with insulating black tape, wrapping tape on the outside can also play a moisture-proof and rust-proof function. Of course, the insulating self-adhesive tape also has its own shortcomings. Although it has good waterproof function, it is easy to break. Therefore, in order to avoid its damage, two layers of plastic tape can be wrapped around the outside as a protective layer, so that the head and the cable can be well protected, so that the cable can be connected smoothly for a long time.

2. How to waterproof the connector?

The connector itself has a waterproof function, but the waterproof level of different types of connectors is different. The waterproof level ranges from 0 to 8. The larger the number, the better the waterproof effect.

When connecting, you can also use high-pressure waterproof tape to improve the waterproof effect of the connector. The use of this high-pressure waterproof tape is the same as that of ordinary plastic insulating tape. You just need to wrap it up.

The advantages of this tape are similar to rubber. The color is generally black, and the texture is relatively soft and thick. After wrapping it with the connector, it becomes a whole, which can completely seal the connector, thereby achieving the purpose of waterproofing the house.

3. Use of cable joint sleeves

Generally, high-hardness, high-quality sleeves are needed on the outside of the cable. The sleeves themselves have good waterproof and fireproof properties, so they can protect the joints from water and fire.

When laying cables underground, sleeves are mostly needed. Sleeves can be mainly divided into rigid sleeves, flexible waterproof sleeves, steel pipe sleeves, and iron sleeves, which can be selected according to the conditions of the construction site.

When connecting metal cable waterproof joints, the correct connection method should be mastered, and irregular connections are strictly prohibited. Once the connection is irregular, the consequences are very serious.
