Wire connector connection method and waterproof method

Wire joints are one thing we often do in our lives. When we install wires in our homes, the connectors of the wires are inevitable. Many people don’t know about the wire connector connection. In fact, the handling of the wire connectors is good or bad. Fully closely related, although they seem to be no different from the layman's point of view, but in fact according to the differences in use and detailed application scenarios and their own post-operational habits, the selection of wire joints is still relatively speaking. More important. There are many ways to connect the wire connectors. What are the connection methods for the wire connectors? How are the wire connectors waterproof? The wire connectors are generally used to tighten the two wires in parallel. In fact, this connection is not acceptable for pulling. The correct connection method is to first screw 1-2 turns in parallel, then separate the wire ends, do not twist and twist 1-2 turns, and then screw them in parallel. The wrapped wire must have good quality high-pressure waterproof tape, the same as the general plastic insulating tape. You can pack it 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.

When there is an external power supply in the wire connector line, the general wire connector is such a connection method, so as to ensure that the wire connector does not cause ignition, short circuit, and poor contact, the branch line is the connection method, the power line The joints are divided into "ten" word connection, "-" word connection method, "Ding" word connection method and so on. The joint should be tight, smooth and thornless. 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), then use insulation self-adhesive tape to stretch about 200% and wrap two or three layers, and finally wrap two Layer of plastic tape. Plastic tape cannot be used directly. Because plastic tape is easy to dislocate and glue at a time; when the electrical load is heavy, the joint heats up, and the plastic tape is easy to melt and shrink; the power connector is pressed in the junction box, and the connector has burrs, which is very simple. Poke empty plastic tape, etc. These dangers directly endanger personal safety, causing moderate lines and forming a fire. The use of insulating black tape will not appear the above situation, it has a certain strength, flexibility, can be wrapped tightly at the joint for a long time, dry and fixed type due to the influence of time and temperature, will not fall, and flame retardant. In addition, it can be protected from moisture and rust by wrapping it with insulating black 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. Wire connector General wire connector is such a connection, to ensure that the wire connector does not accident, in fact, the decorative dark line is not allowed to have a connector, use a little wire to make the connector in the switch junction box, must have a connector Also use the junction box, especially in the online tube, there must be no joints. If there is a joint, it should be in the electric box. This is more secure and not easy to oxidize.
