One-core multi-lead anti-cross wiring bus

The utility model discloses a one-core multi-lead anti-cross wiring bus. The cable comprises an expansion wire core, a lead wire part, an insulating outer sheath and a lead connection part opening, the lead wire part is arranged on the expansion wire core, the lead wire part and the expansion wire core are integrally connected, the expansion wire core is wrapped by the insulating outer sheath, theinsulating outer sheath is provided with a lead connection opening, and the position of the lead connection opening corresponds to the lead connection part on the expansion wire core. The corresponding lead openings are torn at the positions where wiring is needed; therefore, the leads can be led out in parallel at a preset position. If two groups of lead wire parts are arranged on the expansionwire core along the circumferential direction, multi-path lead wires can be respectively carried out in the horizontal direction and the vertical direction. In this way, the requirement for multi-channel parallel wiring of the
