The power cord connector is divided into "ten" word connection, "-" word connection, "D" word connection and so on. The joint should be tightly wound, smooth and without thorns.

1. Wire connector connection method

The power cord connector is divided into "ten" word connection, "-" word connection, "D" word connection and so on. The joint should be tightly wound, smooth and without thorns. Before the thread is disconnected, the thread should be gently pressed with the wire pliers, then wound to the mouth, and then swing left and right, the thread will be disconnected at the joint very obediently. If the joint is in a dry place, first wrap two layers of insulating black cloth, then two layers of plastic tape (also called PVC adhesive tape), and then use J-10 insulating self-adhesive tape to stretch about 200% and wrap two or three layers. Finally wrap two layers of plastic tape. Because the direct use of plastic tape has many shortcomings: the plastic tape tends to be misplaced and opened after a long time; when the electrical load is heavy, the connector heats up, and the plastic tape is easy to melt and shrink; the power connector is pressed against each other in the junction box and the connector has burrs. It is easy to puncture plastic tape, etc. These hidden dangers directly endanger personal safety, cause moderate wiring and cause fire. The above situation will not occur if the insulating black tape is used. It has a certain strength and flexibility, can tightly wrap the joints for a long time, and is a dry fixed type under the influence of time and temperature, will not fall off, and is flame retardant. Furthermore, it can prevent moisture and rust by wrapping it with insulating black tape and then wrapping it with tape. Of course, the insulating self-adhesive tape also has its defects. Although it has good waterproof performance, it is easy to break. Therefore, two layers of plastic tape should be used as a protective layer at the end. The insulating self-adhesive tape of the joint and the joint are non-sticky, and the performance is better.
2.how to waterproof the wire connector

High-pressure waterproof tape, the same usage as ordinary plastic insulating tape, just wrap it up. This kind of tape looks like rubber, like the black, soft, and thicker of a car tire. After wrapping it, it becomes a whole by pinching it. It is completely sealed and not afraid of water. You can buy them everywhere you go to sell electrical materials.

3. Introduction of wire joint casing

For general power cords, high-quality and harder casings should be used. The casings have better fireproof and waterproof performance.

Casing, usually used in the basement of a building, is used to protect pipes or iron rings to facilitate pipe installation.

The classification of casing: rigid casing, flexible waterproof casing, steel pipe casing and iron casing, etc.
