Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
The pedestal of single-phase leakage switch all can there be three leading-out terminals, respectively: zero line leading-out terminal, ground wire leading-out terminal and live wire leading-out terminal.As shown in Figure 1, three leading-out terminals of existing single-phase leakage switch are linear arrangement structure, and the such arrangement architecture of leading-out terminal exists following defect:
(1) as shown in Fig. 2 wiring schematic diagram, inlet wire main push-towing rope 6 is three cores, connects the zero line leading-out terminal 3 of single-phase leakage switch, ground wire leading-out terminal 4 and live wire leading-out terminal 5 respectively.Because three leading-out terminals are linear arrangement structure, therefore the connection conductor length of both sides leading-out terminal (figure being zero line leading-out terminal 3 and live wire leading-out terminal 5) can be greater than the connection conductor length of middle leading-out terminal (ground wire leading-out terminal 4), so in the process of wiring, need the connection wire of middle leading-out terminal to cut off a part, cause the waste of material;
(2) same as shown in Fig. 2 wiring schematic diagram, turn again behind the connection wire palpus sharp turn of both sides leading-out terminal (figure being zero line leading-out terminal 3 and live wire leading-out terminal 5) and reach leading-out terminal, bring great inconvenience to wiring work, add the difficulty of wiring work.
As shown in Figures 3 and 4; a kind of single-phase earth leakage protection switch; comprise pedestal 1, upper cover 2, zero line leading-out terminal 3, ground wire leading-out terminal 4 and live wire leading-out terminal 5; described upper cover 2 covers on described pedestal 1; described zero line leading-out terminal 3, ground wire leading-out terminal 4 and live wire leading-out terminal 5 are on described pedestal 1, and the center of described zero line leading-out terminal 3, ground wire leading-out terminal 4 and live wire leading-out terminal 5 is not on the same line.
When the center of the outlet port of described zero line leading-out terminal 3, ground wire leading-out terminal 4 and live wire leading-out terminal 5 is in the same plane, and three described outlet ports intersect at a point towards the extended line of described inlet wire main push-towing rope 6.
When the center of the outlet port of described zero line leading-out terminal 3, ground wire leading-out terminal 4 and live wire leading-out terminal 5 is not in the same plane, and three described outlet ports intersect at a point towards the projection line of the extended line in the vertical direction of described inlet wire main push-towing rope 6.
Preferably, the center of described zero line leading-out terminal 3, ground wire leading-out terminal 4 and live wire leading-out terminal 5 is on same circular arc line 7, the point that the projection line that the leading-out terminal being in both sides is respectively point that zero line leading-out terminal 3 and live wire leading-out terminal 5, three described outlet ports intersect towards the extended line of described inlet wire main push-towing rope or in the vertical direction intersects is positioned at described inlet wire main push-towing rope 6.As shown in Figure 5, center due to zero line leading-out terminal 3, ground wire leading-out terminal 4 and live wire leading-out terminal 5 is on same circular arc line, and the outlet port of zero line leading-out terminal 3 and live wire leading-out terminal 5 intersects at a point towards the extended line I 8 of described inlet wire main push-towing rope 6 and extended line II 9, thus inlet wire main push-towing rope 6 points three strands connects three leading-out terminals and zero line leading-out terminal 3, ground wire leading-out terminal 4 is consistent with the connection conductor length of live wire leading-out terminal 5, above-mentioned situation of cutting section wire would not be there is, save material.On the other hand, the center of zero line leading-out terminal 3, ground wire leading-out terminal 4 and live wire leading-out terminal 5 is on same circular arc line, inlet wire direction after the outlet port position of leading-out terminal and inlet wire main push-towing rope 6 points three strands is adapted, wiring work is more prone to, thus greatly reduce the difficulty of wiring work, improve operating efficiency, wiring is simultaneously more attractive in appearance.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
