Welding tutorial for wires, terminals and terminals

The terminal is a part used to facilitate the welding of the weldment and the wire. It is essentially a piece of metal sheet in the sealed insulating material. There are jacks at both ends to insert the wire for welding, and some terminals have screws. For tightening or loosening, it is suitable for interconnecting a large number of wires. There are many types of binding posts: flakes, columns, tubes, etc., among which the flakes with holes are called openings and the cuts are also called openings. The column-shaped binding posts are grooved for hooking the wires to facilitate welding, and the tubular binding posts are also slotted on both sides and slotted on one side.


The welding methods of wires, terminals and terminals are also divided into lap welding, hook welding and winding welding, as shown in Figure 1.

Wrap the end of the wire passing through the tin on the terminal, and then use pliers to tighten the wound wire, and then perform the welding operation. When winding, the wire should be vertically wound around the terminal relative to the terminal. The winding must be neat and firm. Otherwise, if the winding is loose during welding, the welding will be loose and dull due to the loose wire, and it will also cause virtual welding. . After winding, excess wire should be cut off with diagonal pliers.


The hook group bends the end of the tinned wire into a hook shape and hooks it on the terminal, and then clamps it with needle nose pliers before welding. Note that the joint between the wire and the terminal cannot be loose. The welding strength of hook welding is lower than that of winding welding, but the welding is simple and easy to operate, so it is more convenient to use the method of hook welding in cases where no particularly high strength is required.


Lap welding laps the end of the tinned wire to the wire terminal for welding. Lap welding is the simplest welding method, but it has the weakest strength and reliability. It is suitable for maintenance and temporary welding and is inconvenient to wind. The place.
