How to waterproof the wire connector
High-pressure waterproof tape, the same as the general plastic insulation tape, can be wrapped up. This kind of tape looks like rubber. It is like the black, soft, and thick car tires. When it is wrapped, it will be put into a whole, completely sealed, not afraid of water. You can buy it where you can sell electrical materials.
Wire connector connection
The power cord connector is divided into "ten" word connection method, "-" word connection method, "Ding" word connection method and so on. The joint should be tightly wrapped and lubricated without thorns. Before disconnecting the wire head, first press it with a wire cutter wire, then wrap it around the mouth, then swing it to the left and right, and the wire end will be disconnected at the joint very conformally. If the joint is in a dry place, first wrap two layers with insulating black cloth, then wrap two layers of plastic tape (also called PVC adhesive tape), and then use J-10 insulation self-adhesive tape to stretch about 200% and wrap two or three layers. Finally wrapped in two layers of plastic tape. Due to the shortcomings of direct use of plastic tape: plastic tape is easy to dislocate and glue open at a time; when the electrical load is heavy, the joint heats up, the plastic tape is easy to melt and shorten; the power connector is pressed in the junction box, and the connector has burrs, very Simply poke empty plastic tape, etc. These hidden dangers directly endanger personal safety, causing moderate lines and causing fires. The use of insulating black tape will not present the above situation. It has a certain strength and flexibility. It can be wrapped tightly at the joint for a long time. It is dry-fixed due to the influence of time and temperature, does not fall, and is flame retardant. In addition, it can be protected from moisture and rust by wrapping it with insulating black rubber tape. Of course, the insulating self-adhesive tape also has disadvantages. Although it has good waterproof function and is easy to break, it is necessary to wrap two layers of plastic tape as a protective layer. The insulating self-adhesive tape of the joint and the joint is not sticky to each other, and the function is better.
