The assembly relation of the trip gear that the present embodiment provides is further illustrated below in conjunction with Fig. 2-Figure 14.
Magnet converter 1 is contained in the first chamber 31 place of bracket shell 3, and the lead-in wire of coil 13 is stretched from the second breach 37 of bracket shell 3.In the push rod 21 of STATEMENT OF FEDERALLY SPONSORED 2, slide unit 211 is through the guide groove 71 of bracket shell 3, and dropout push rod 213 is through the second breach 37 of bracket shell 3.Two rollers 22 of STATEMENT OF FEDERALLY SPONSORED 2, aim at the shade 161 of the top cap 16 of magnet converter 1.Button 5 is inserted in bracket shell 3 from open slot, and two rollers 22 of STATEMENT OF FEDERALLY SPONSORED 2 are aimed on 2 inclined-planes 51 respectively.The locating channel 54 of button 5 coordinates with the positioning boss 73 of bracket shell 3.The circle 62 of turning round of torsion spring 6 is enclosed within bracket shell 3 body 38, and 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 are inserted in 2 spacing barbs 53 of button 5 respectively, prevent the stressed disengaging of torsion spring.
Finally by cover plate 4 and bracket shell 3, it is connected: the lower positioning boss 45 of cover plate 4 inserts the lower square hole 32 (in Figure 14 F point) of bracket shell 3, cover plate 4 rotates around lower positioning boss 45, guide groove 71 is aimed at the slide unit 211 of the push rod 21 of STATEMENT OF FEDERALLY SPONSORED 2, sliding part is shown in, and 211 through guide groove 71.Finally by two of cover plate 4 upper positioning boss 41 with cambered surface, in two upper aperture 35 of press-in bracket shell 3 (in Figure 14 E point), now cover plate 3 is lockable, and cannot separate.So far, this leakage tripping device has been assembled.
The wherein deep gouge 72 of bracket shell 3 and cover plate 4 coordinates with the die 215 of STATEMENT OF FEDERALLY SPONSORED 2.Its effect prevents die long, affects STATEMENT OF FEDERALLY SPONSORED 2 and slide in the guide groove of bracket shell 3 and cover plate 4.
Further illustrate the operation principle of the trip gear that Fig. 2-14 provides below: first, leakage tripping device is in trip status, as shown in Figure 6, in this condition, applies a pressure F downwards, as shown in Figure 4 to button 5.Button 5 overcomes reduction torsion spring 6 and moves downward, and about it, 2 inclined-planes 51 are tangent with the roller disc 221 of 2 rollers 22 of STATEMENT OF FEDERALLY SPONSORED 2.Because roller 22 is together with push rod 21 riveting, roller 22, by the pressure F of button 5, can not move up and down, can only carry out horizontal movement.As shown in Figure 4, under the effect of horizontal component F1, the roller disc 221 of roller 22 promotes shade 161 in the top cap 16 of magnetic flow convertor 1, the dropout elastomer 15 of magnetic flow convertor 1 is compressed, drive dynamic magnetic core 14 to move (as shown in figure 12) toward the direction of permanent magnet 12 simultaneously, 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, above the protruding plate 52 that the locking bar 212 of STATEMENT OF FEDERALLY SPONSORED 2 just in time runs to button 5 (as shown in Figure 4), now remove pressure F, button 5 can up move, until the protruding plate 52 of button 5 contacts with the locking bar 212 of STATEMENT OF FEDERALLY SPONSORED 2 under the reaction force of reduction torsion spring 6.The locking bar 212 of STATEMENT OF FEDERALLY SPONSORED 2 has caught on button 5 (the C point in Fig. 5), achieves the effect of pinning button 5, as shown in Figure 5.
When product has electric leakage to occur, the voltage signal that detection of electrons part can give the coil 13 1 of magnetic flow convertor 1 suitable.The electromagnetic force F that coil 13 produces
line, direction with forever contrary with the suction F of permanent magnet 12, when meeting F
line+ F
bullet>F
forevertime, magnetic core 14, together with the cap 16 of top, outwards can move (Figure 13) under the reaction force of dropout elastomer 15.When the top cap 16 of magnetic flow convertor 1 is pushed open by dropout elastomer 15, the roller 22 of STATEMENT OF FEDERALLY SPONSORED 2 and push rod 21 can be promoted toward front slide, and STATEMENT OF FEDERALLY SPONSORED 2 dropout push rod 213 promote in circuit breaker switch maintaining body, circuit breaker is disconnected, as shown in Figure 6.
Simultaneously, the locking bar 212 of STATEMENT OF FEDERALLY SPONSORED 2 leaves the surface of the protruding plate 52 of button 5, button 5 moves upward under the reaction force of torsion spring 6, and the surface contact of protruding plate 52 is to D point position (as shown in Figure 6) of bracket shell 3, and button 5 resets to initial position.The height that button 5 upwards runs is exactly the height of button 5 dropout instruction.Fig. 4, Fig. 5 and Fig. 6 are that release resets, release normally works and release dropout indicating status respectively.Release will switch between these 3 states.In figure, H is the difference in height of button 5 upper surface and bracket shell 3.Wherein, H1 is the height of release when resetting, and H2 removes button height after external force F, H3 be electric leakage thread off instruction time, the height of button.The difference in height of H3-H1 is exactly that button is down pressed until stroke when resetting.The difference in height of H3-H2 is exactly the height that after release is threaded off, button ejects instruction.
