Splices and joints are two names for essentially the same thing, that is, methods of connecting two pieces of wire so as to carry either a signal or an electrical current. Usually, these types of connections are achieved using a soldering iron. However, it is highly important that the splice or joint be strong regardless of whether solder has been applied or not. Several ways exist in which to accomplish this sort of a connection. Knotted tap joint A tap splice connects a loose wire to a conductor in a perpendicular shape. This joint resembles a “T” shape, with the connecting wire intersecting the running one.
Tap splices allow loose wires to tap the electrical flow of an active wire. Double cross joint The double connection joint (cross joint) is a cross joining piece of carrying profiles type CD (CD50 / CD60), made by cold lamination from zinced steel sheet, 0. 8 mm thick, Used intersection nodes of carrying profiles type CD under normal loading conditions. Rat tail joint A rattail joint is used with wiring that is placed into a junction box or conduit. Once again, about 5 inches of insulation is removed from both sides of the joint.
The two sections of wire are simply crossed into an “X” and twisted together so that they form one section of twisted wire pointing straight up from the endpoints of the wires’ insulation. Square knot joint A common double knot in which the loose ends are parallel to the standing parts, most often used to join the ends of two cords or lines. The Western Union splice is the most common type of wire splice. The technician then wraps the end of each piece of wire around the other side of the joint five or six times, cuts off the excess from both the ends and pinches the end down with pliers.
This type of connection is used to splice small, solid conductors together. The Western Union splice works best to splice together small, solid conductors. It is the most common type of wire splice. To make the Western Union splice, first remove about five inches of insulation from both wires and cross the exposed wires. Wrap one wire around the other five or six times, and then do the same with the other.
