(2) This switching device's binding post, there are four characteristics relevant with the wiring in the wiring shell fragment: firstly, when a small-specification wire is connected, the characteristic that a wiring elastic sheet abuts against the long edge of a current conducting plate needs to be kept away by a distance corresponding to the size of the connected wire, so that the wire can be pressed and connected by the long edge of the elastic sheet, at the moment, the force generated by deformation after the elastic sheet is pressed and connected with the wire is the wiring force of the wire, the main force application characteristic is that the wire is ensured to be stably and reliably contacted with the current conducting plate, and the tail end of the long edge of the wire is provided with a tip for increasing the force for pulling out the wire, so that the; secondly, the long edge characteristic of the elastic sheet is forced to deform by utilizing the convex characteristic on the elastic sheet, and the long edge of the elastic sheet is far away from the current conducting plate by utilizing the downward force of the pressing piece, so that a lead with enough size can be placed; the pressing component can be a sliding block or a screw; the left side of the elastic sheet leans against the wire holder to limit the wire holder; and fourthly, when the large-size lead is connected, the lead is firstly pressed against the lower pressing piece to enable the distance between the tip of the lead and the conductive plate to reach the distance for placing the large-size lead, so that the deformation of the two sections of elastic sheets is required to be exerted, and the final connecting force for pressing and connecting the large-size lead is formed.
