The connection between the wire and the wire, the connection between the end of the wire and the terminal post, is a small matter and a big responsibility. This article is accompanied by pictures and texts, so that you can understand clearly! ! The connection of the wire is as follows: Straight line connection and T-shaped connection of single copper core wire; Butt connection of double-stranded wires; Straight line connection and T-shaped connection of multiple copper core wires; Butt connection of unequal diameter copper wires; The single-strand line is connected with the T-branch of the multi-strand line; Connection of flexible wire and single-strand hard wire; The aluminum core wire is crimped with crimping tube; The aluminum core wire is crimped with a crimping tube. 1 Straight-line connection of single-strand copper conductor First intersect the core wires of the two wires in an X shape. Straighten the two thread ends after twisting each other for 2 to 3 turns. Put each end of the thread close to the other core wire and wind it around 6 times, cut off the remaining core wire with wire cutters, and clamp the end of the core wire flat. 2 T-shaped connection of single-strand copper conductor Intersect the end of the branch core wire with the main core wire cross, leave 5mm at the root of the branch core wire, then wind it clockwise for 6 to 8 times, cut the remaining core wire with wire cutters, and clamp the core wire flat End. The core wire of small cross-section need not be knotted. 3 Butt of double stranded wire Cut the ends of the two twin wires into the form shown in the figure. When connecting, connect the core wires of the same color in the two thread ends to be connected in a straight line connection with a small cross section. Use the same method to connect the core wires of another color together. 4 Straight connection of multi-strand copper conductors Take 7-strand copper core wire as an example to illustrate the straight-line connection method of multi-strand copper core wire First spread and straighten the core wire ends of the stripped insulation layer, then twist the core wire close to the 1/3 line segment of the insulation layer tightly, and then disperse the remaining 2/3 core wire ends into an umbrella shape as shown in the figure. The core wire is straightened. Align the ends of the two rib-shaped wires with each other and insert them to the end. Pinch all the core wires on both sides of the fork, and straighten each core wire and make the interval between each core wire even; at the same time, use wire pliers to tighten the fork to eliminate the gap. First, at one end, fold the adjacent two strands of core wire at the diameter width of about 3 single strands from the center line of the fork, and form a 90°. Then twist the two strands of core wire in a clockwise direction for 2 turns, then fold it back 90° and lie flat on the axis position before folding. Next, fold the two adjacent core wires immediately before lying down to 90°, and process them according to step ⑤. When winding the remaining 3 core wires to the second turn according to step ⑤, cut the first 4 core wires at the roots and clamp them flat; then wrap the 3 core wires with feet 3 times, then cut off the remaining ends, and clamp Flat cut without burrs The other side is processed according to steps ④～⑦. 5 T-shaped connection of multi-strand copper conductors Take 7-strand copper core wire as an example to illustrate the T-shaped connection method of multi-strand copper core wire Distribute and straighten the branch core wires, then twist the core wires close to the 1/8 line segment of the insulation layer tightly, divide the remaining 7/8 core wires into two groups, one group of 4, the other group of 3, row Qi. Use a screw chisel to pry the core wires of the main wire into two groups, then insert a set of 4 core wires in the branch line into the middle of the main wire core wire, and put a group of 3 core wires in front of the main wire core wire. Tightly wind a set of 3 core wires clockwise on the right side of the trunk line for 3~4 turns, and clamp the flat end; wind a set of 4 core wires on the left side of the trunk line in a counterclockwise direction for 4~5 turns . Clamp the flat wire end. 6 Butt connection of unequal diameter copper wires Wrap the end of the thin wire tightly around the end of the thick wire for 5-6 times, bend the end of the thick end to press it on the winding layer, then wind the end of the thin wire 3 to 4 times, cut off the remaining end, and flatten the cut. 7 T-branch connection of single-stranded and multi-stranded lines On the core wire 3~5mm away from the left end of the insulating layer opening of the multi-stranded wire, use a screwdriver to divide the multi-stranded core wire into two evenly divided groups (such as 3 or 4 points for the 7-strand core wire). Insert the single-strand core wire into the middle of the two sets of core wires of the multi-strand core wire, but the single-strand core wire cannot be inserted to the end, and the insulation layer should be about 3mm away from the multi-strand core wire. Then use wire cutters to clamp the multi-strand core wire inserting pliers flat. Wrap the single-strand core wire tightly on the multi-strand core wire in a clockwise direction. The loops should be tightly packed and wrap around 10 times; then cut off the remaining end and clamp the cut burr. 8 Connection of flexible wire and single-strand hard wire First twist the flexible wire into a single-strand wire, then wind the single-strand hard wire 7 to 8 times, and finally bend the single-strand hard wire backwards to prevent the binding from falling off. 9 Crimping of aluminum core wire with crimping tube Before wiring, first select a suitable crimping tube, remove the oxide layer and dirt on the surface of the wire end and the inner opening of the crimping tube, and apply neutral petroleum jelly. Insert the two thread ends into the crimping tube and pass them out of the crimping tube, so that the two wire ends extend out of the crimping tube by 25~30mm. Crimping with crimping pliers. If the steel core aluminum stranded wire is crimped, a layer of aluminum gasket should be placed between the two core wires. The number of crimping pits of the crimping pliers on the crimping pipe is usually 4 indoor thread ends and 6 outdoors. 10 Crimping of aluminum core wire with crimping tube Before connection, use a wire brush to remove the oxide layer and dirt on the inner wall of the wire head and the groove clamp wire slot, apply petroleum jelly powder (or neutral petroleum jelly), and then clamp the wire into the wire slot and tighten the bolts , So that the groove line is clamped tightly and clamped to complete the connection. To prevent the bolts from loosening, the compression bolts should be covered with spring washers.
