1. Cable connection method
Power cord connectors are divided into “+ word connection method”, “- word connection method”, “T-word connection method” and so on. Seams should be tangled, smooth and unnecessary. Before the wire ends are disconnected, the clamp wire should be lightly pressed, then wrapped around the mouth, then wiggled from side to side, and then connected to the connector to disconnect. If the joint is in a dry place, it should be wrapped with two layers of insulating black cloth, then two layers of plastic tape (also known as PVC adhesive tape), and then wrapped with J-10 insulating self-adhesive tape stretched about 200% Two or three layers, and finally two layers of plastic tape.
Because the direct use of plastic has many disadvantages: plastic tape is prone to glue dislocation and glue opening; when the electrical load is heavy and the connector is hot, the plastic tape is easy to melt and shrink; the power connectors are pressed against each other in the junction box, and the connectors have burrs. Poke plastic tape, etc. These hidden dangers directly endanger personal safety, make the line moderate, and cause fire. However, it does not happen with insulating black tape, it has a certain strength, flexibility, can be wrapped in seams for a long time, is affected by time and temperature and dry fixed type, does not fall off, and is flame retardant.
In addition, after the tape is wrapped with insulating black tape, it can prevent moisture and rust. Of course, the insulating self-adhesive tape also has defects. Although it has good waterproof performance, it is easy to break, so in the end, it is wrapped with two layers of plastic tape as a protective layer. The insulating self-adhesive tape of the joint does not stick to the joint, and the performance is also better it is good.
2.How to waterproof the cable connector
High pressure waterproof tape, like ordinary plastic insulating tape, can be packaged. This tape looks like rubber, black like a car tire, soft, and thicker, wraps, and clips into a complete, completely sealed seal that’s not afraid of water. You can buy it anywhere that sells electrical materials
