[0025] The main wiring segment 2 includes a first wire 21, a second wire 22, a third wire 23, and a fourth wire 24, which are housed within the first fireproof layer 6 and respectively connected to the plug 1. One end of each of the first wire 21, second wire 22, third wire 23, and fourth wire 24 is inserted into a wire hole in the plug 1. (See also...) Figure 1 In this embodiment, the first conductor 21 and the second conductor 22 are spirally wound together, and the third conductor 23 and the fourth conductor 24 are spirally wound together. They are all fixed together by one or more loop-shaped stranded wires to prevent the conductors from unraveling.

[0026] One end of the first wire 21 passes through the first sleeve 3 relative to the plug 1 and is connected to the first terminal 7. One end of the second wire 22 passes through the first sleeve 3 relative to the plug 1 and is connected to the second terminal 8. The first wire 21 and the second wire 22 passing through the first sleeve 3 form the first branch segment 4.
