Abstract
A wiring device includes a plurality of trenches and a plurality of channel sets. The trenches at least include a first trench, a second trench and a third trench, bottoms of which are respectively located at different height positions. Each of the channel sets at least includes a first channel, a second channel and a third channel. The first channels penetrate the wiring device from an outer sidewall thereof to the first trenches, respectively, the second channels penetrate the wiring device from the outer sidewall thereof to the second trenches, respectively, and the third channels penetrate the wiring device from the outer sidewall thereof to the third trenches, respectively. The wiring device has the advantages of a simple structure and a low cost for molding and manufacturing, and is suitable to perform winding by a manual or automatic machine and thus can prevent first output wires of the coil windings with in phase or out of phase from entangling or knotting with each other.
