The second metal conductive sheet 14 is installed in the second through groove 21. Strip the outer skin from one end of the first wire 9 to expose the inner core of the first wire 9. Bend the inner core into a ring so that the first fixing bolt 7 can pass through the ring. Use the first fixing bolt 7 to fix the first wire 9 on the first metal conductive sheet 4. At this time, the inner core of the first wire 9 is in close contact with the first metal conductive sheet 4 under the action of the first fixing bolt 7.

The first wire 9 and the second wire 19 are conducted through the contact of the first metal conductive sheet 4 on the first wiring terminal 2 and the second metal conductive sheet 14 on the second wiring terminal 12, achieving the effect of conducting two lines. When it needs to be disconnected, just pull out the second docking hole 20 from the first docking hole 10.
