1. the automatized assembly method of an earth leakage protective device, it is characterised in that:

  • described earth leakage protective device includes;

    by bottomAnd the housing (1) that forms of upper cover (102) and be respectively positioned on the internal waterproof pin base (19) of housing (1), zero line pin (101)(3), live prong (4), earth pin (5) and wiring board (6), press-key structure, pin press strip (7), crosspiece (8), zero line shell fragment(9), live wire shell fragment (10) and ground wire shell fragment (11);

    Described crosspiece (8) be provided with three respectively with zero line shell fragment (9), live wire bulletSheet (10) and the compression end (81) of ground wire shell fragment (11) correspondence;

    Described automatized assembly method includes;

    Step S1, after zero line pin (3), live prong (4), earth pin (5) are nested on waterproof pin base (19),By zero line pin (3), live prong (4), earth pin (5) and the zero line jack on bottom (101), firewire jack, ground wireThis waterproof pin base (19) is installed on bottom (101) by the matching relationship of jack;

    Step S2, is nested in zero line shell fragment (9), live wire shell fragment (10), ground wire shell fragment (11) on waterproof pin base (19), andGuarantee that zero line pin (3) is the most corresponding with the position of zero line shell fragment (9), the position phase of live prong (4) and live wire shell fragment (10)Correspondence and earth pin (5) are the most corresponding with the position of ground wire shell fragment (11) mutually;

    Step S3, is installed on crosspiece (8) on waterproof pin base (19), and when guaranteeing instantly to press crosspiece (8), described crosspiece(8) can by its compress end (81) drive zero line shell fragment (9), live wire shell fragment (10) move down and respectively with zero line pin (3), live wirePin (4) separates and power-off;

    When moving on crosspiece (8) resets, described crosspiece (8) can compress end (81) by it and drive zero line bulletSheet (9), live wire shell fragment (10) are upper to be moved and contacts with zero line pin (3), live prong (4) and be energized respectively;

    Step S4, installs pin press strip (7), relay (103) and transformer (2);

    Wherein pin press strip (7) is installed on waterproofThe top of pin base (19), and guarantee that three exits of pin press strip (7) withstand zero line pin (3), live wire separately downPin (4) and earth pin (5);

    Step S5, is installed to wiring board (6) top of waterproof pin base (19), loads press-key structure on wiring board (6),And guarantee that press-key structure is connected with crosspiece (8), and controllable this crosspiece (8), upper cover (102) is installed afterwards.
