The assembly relation of the trip gear of the present embodiment offer is be provided below in conjunction with Fig. 2-Figure 14.

Magnet converter 1 is at the first chamber 31 of bracket shell 3, and the lead of coil 13 is from the second of bracket shell 3 Stretched at breach 37.Slide unit 211 passes through the guide groove 71 of bracket shell 3, dropout push rod 213 in the push rod 21 of STATEMENT OF FEDERALLY SPONSORED 2 Through the second breach 37 of bracket shell 3.Two rollers 22 of STATEMENT OF FEDERALLY SPONSORED 2, the shade of the top cap 16 of alignment magnet converter 1 161.Button 5 is inserted in bracket shell 3 from open slot, and 2 inclined-planes 51 are respectively aligned to two rollers 22 of STATEMENT OF FEDERALLY SPONSORED 2.Button 5 The positioning boss 73 of locating channel 54 and bracket shell 3 coordinates.The torsion circle 62 of torsion spring 6 is enclosed on the cylinder 38 of bracket shell 3, The position limit arm 61 of torsion spring 6 is inserted in the crotch 39 of bracket shell 3, prevents torsion spring 6 from rotating.2 torque arm 63 of torsion spring 6 be inserted in respectively by In 2 spacing barbs 53 of button 5, prevent torsion spring stress from departing from.

Finally by its mating connection of cover plate 4 and bracket shell 3：The lower positioning boss 45 of cover plate 4 is inserted under bracket shell 3 Square hole 32 (F points in Figure 14), cover plate 4 are rotated around lower positioning boss 45, and guide groove 71 is aligned to the slip of the push rod 21 of STATEMENT OF FEDERALLY SPONSORED 2 Part 211, sliding part is set to see that 211 pass through guide groove 71.The upper positioning boss 41 for finally carrying cambered surface by two of cover plate 4, press-in In two upper apertures 35 of bracket shell 3 (E points in Figure 14), now cover plate 4 is lockable, and can not be separated.So far, the electric leakage is threaded off Device is completed.

The wherein deep gouge 72 of bracket shell 3 and cover plate 4, coordinated with the die of STATEMENT OF FEDERALLY SPONSORED 2 215.Its effect is to prevent Die is long, influences STATEMENT OF FEDERALLY SPONSORED 2 and is slided in the guide groove of bracket shell 3 and cover plate 4.

The operation principle for the trip gear that Fig. 2-14 is provided is further illustrated below：First, leakage tripping device, which is in, threads off State, as shown in fig. 6, in this condition, being downwardly applied to a pressure F to button 5, as shown in Figure 4.Button 5 overcomes reset to turn round Spring 6 moves downward, and the roller disc 221 on its left and right 2 inclined-planes 51 and 2 rollers 22 of STATEMENT OF FEDERALLY SPONSORED 2 is tangent.Due to roller 22 with The riveting of push rod 21 together, pressure F of the roller 22 by button 5, it is impossible to move up and down, horizontal movement can only be carried out.As shown in figure 4, In the presence of horizontal component F1, shade 161 in the top cap 16 of the promotion magnetic flow convertor 1 of roller disc 221 of roller 22, make magnetic The dropout elastomer 15 of logical converter 1 compresses, while drives dynamic magnetic core 14 to move (as shown in figure 12) toward the direction of permanent magnet 12, Until magnetic core 14 and permanent magnet 12 are separated by certain distance, at this moment magnetic core 14 is firmly held (as shown in figure 13) by permanent magnet 12. Dropout elastomer 15 is reduced to maximum, and leakage tripping device completes hand-reset, as shown in Figure 4.When leakage tripping device resets, linkage The locking bar 212 of part 2 just runs to the top of protruding plate 52 (as shown in Figure 4) of button 5, now removes pressure F, and the meeting of button 5 exists Up moved under the reaction force of reduction torsion spring 6, until the protruding plate 52 of button 5 contacts with the locking bar 212 of STATEMENT OF FEDERALLY SPONSORED 2.Linkage The locking bar 212 of part 2 has caught on button 5 (the C points in Fig. 5), realizes the effect for pinning button 5, as shown in Figure 5.

When product has electric leakage, detection of electrons part can give the coil 13 1 of magnetic flow convertor 1 appropriate voltage letter Number.Electromagnetic force F lines caused by coil 13, direction meet F line+F bullets on the contrary, working as forever with the suction F with permanent magnet 12>F forever when, Magnetic core 14 and top cap 16 together, can move out (Figure 13) under the reaction force of dropout elastomer 15.In magnetic flow convertor 1 Top cap 16 is released elastomer 15 when pushing open, can promote STATEMENT OF FEDERALLY SPONSORED 2 roller 22 and push rod 21 toward front slide, and STATEMENT OF FEDERALLY SPONSORED 2 Dropout push rod 213 promote breaker in switch maintaining body, disconnect breaker, as shown in Figure 6.

Meanwhile the locking bar 212 of STATEMENT OF FEDERALLY SPONSORED 2 leaves the surface of the protruding plate 52 of button 5, reaction force of the button 5 in torsion spring 6 Lower motion, the surface of protruding plate 52 upwards touch the D points position (as shown in Figure 6) of bracket shell 3, and button 5 is reset to initially Position.The height that button 5 is run up, it is exactly the height of the dropout instruction of button 5.Fig. 4, Fig. 5 and Fig. 6 are that electrical apparatus release is answered respectively Position, electrical apparatus release normal work and electrical apparatus release dropout instruction state.Electrical apparatus release will switch between this 3 states.In figure, H be by The upper surface of button 5 and the difference in height of bracket shell 3.Wherein, H1 is height when electrical apparatus release resets, and H2 is to remove button after external force F Highly, when H3 is electric leakage dropout instruction, the height of button.H3-H1 difference in height be exactly button down press until reset when row Journey.H3-H2 difference in height is exactly the height of button ejection instruction after electrical apparatus release is threaded off.
