The utility model content
Technical problem to be solved in the utility model is that the operating mechanism and the magnetictrip assembling back upper level that solve in the electromagnetic-type leakage circuit breaker are inconsistent, causes the inharmonic problem of loam cake outward appearance.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of electromagnetic-type leakage circuit breaker operating mechanism, comprise the latching device and the tripping mechanism that are arranged between the left side plate, magnetictrip and magnetictrip mounting bracket, the longitudinal cross-section of described magnetictrip mounting bracket takes the shape of the letter U, the U-shaped bottom surface of this mounting bracket is provided with and the suitable installing hole of magnetictrip erection support, the right side of magnetictrip mounting bracket and the outer surface of left plate is fixed and the U-shaped opening forward, the magnetictrip installing hole upper surface interior and magnetictrip that the erection support of magnetictrip is inserted on the magnetictrip mounting bracket is concordant with the upper surface of left plate, vertical the offseting of dropout plate upper surface in magnetictrip push rod external part and the tripping mechanism, and the magnetictrip push rod promotes the dropout plate when stretching out and moves downward and make the latching device release.
Also comprise test bracket in the such scheme, its rear surface is provided with the slot of the U-shaped opening that is used to connect the magnetictrip mounting bracket, and described test bracket is inserted on the magnetictrip mounting bracket.
The utility model is compared with traditional residual current circuit breaker operating mechanism, the upper surface of magnetictrip mounting bracket is concordant with the upper surface of left plate fixing, therefore after magnetictrip is installed, its upper surface is concordant with the upper surface of left plate, so electro-magnetic circuit breaker assembling back loam cake is concordant, and the product total height is no more than the installation dimension of distribution lighting case, is installed in the distribution box to coordinate with other terminal appliance outward appearance.

Embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As shown in Figure 1, the utility model comprises latching device and the tripping mechanism that is arranged between the left and right side plate 21,22, magnetictrip 23 and magnetictrip mounting bracket 24, and wherein latching device is all identical with existing product with tripping mechanism.
In conjunction with Fig. 2, Fig. 3 and shown in Figure 4, the longitudinal cross-section of described magnetictrip mounting bracket 24 takes the shape of the letter U, the U-shaped bottom surface of this mounting bracket is provided with the installing hole 26 suitable with the magnetictrip erection support, the outer surface of the right side of magnetictrip mounting bracket 24 and left plate 21 fix and U-shaped opening 25 forward, magnetictrip installing hole 26 upper surfaces interior and magnetictrip 23 that the anterior erection support 28 of magnetictrip 23 is inserted on the magnetictrip mounting bracket 24 are concordant with the upper surface of left plate 21, and the rear portion erection support 29 of magnetictrip 23 is fixed on the left plate 21 by set bolt and regulating spring 31.Vertical the offseting of upper surface of the dropout plate 27 in the push rod external part of magnetictrip 23 and the tripping mechanism, and the push rod of magnetictrip 23 promotes dropout plate 27 when stretching out and moves downward and make the latching device release.
The rear surface of test bracket 30 is provided with the slot of the U-shaped opening that is used to connect the magnetictrip mounting bracket, and described test bracket 30 is inserted on the magnetictrip mounting bracket 24.
Fig. 5 is the utility model latching device and tripping mechanism structural representation, as shown in Figure 5, during use, handle 3 under external force, rotate around connecting axle 15, drive lower link 13, middle connecting rod 12, last connecting rod 11 and cam 14 actions, lower link 13 is moved downward, so the moving contact of residual current circuit breaker and fixed contact closure, snap close 7 pins tripping under the effect of latch spring 8, this moment, handle 3 was pushed down dropout sheet reset spring 10, dropout plate 27 be not subjected to the threading off effect of sheet reset spring 10 elastic force, when magnetictrip 23 obtains trip signal, push rod can move, and on dropout plate 27, can apply power vertically downward, drive snap close 7 actions, tripping obtains release at this moment, handle 3 is got back to original position under the effect of handle spring 4 power, and drive lower link 13, middle connecting rod 12, last connecting rod 11, cam 14 actions, lower link 13 is got back to initial position, makes the moving contact of residual current circuit breaker get back to original position. at this moment, handle 3 does not withstand dropout sheet reset spring 10, dropout sheet reset spring 10 drives dropout sheet reset 27 magnetictrip 23 push rods and resets together, thereby the realization operating mechanism is detained again.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection range of the present utility model.
