Embodiment
Fig. 1 and Fig. 2 schematically illustrates the auxiliary switch 1 according to the first execution mode of the present invention, and wherein auxiliary switch 1 is in the close position in FIG, and is in open position in fig. 2.Auxiliary switch 1 comprises housing 11, fork 12, transducer 13 and the cam 15 as actuator.Housing 11 is made through injection moulding usually.One end and the housing 11 of fork 12 are pivotally connected to axle 17, and can rotate around axle 17 thus its other end 18 can be moved within the specific limits.Such as the transducer 13 of sensitive switch is positioned at the side of fork 12, and cam 15 is positioned at the opposite side of fork 12.The contact pin 131 of sensitive switch is pressed against the part of the other end 18 close to fork 12.Cam 15 comprises two flanges, and rotates by the driving mechanism (not shown) driving of driving stage 3 (see Fig. 8).When cam 15 rotates on housing 11, described flange can be resisted against on the side of fork 12, and drive fork 12 pivotally to rotate certain angle around axle 17, thus the contact chip 131 making fork 12 trigger sensitive switch sends the signal of telecommunication through contact pin 132 (Fig. 7 only marked one in 3 contact pin).The contact 131 of preferred cam 15 and sensitive switch is positioned at the other end 18 near fork 12, the contact 131 (as shown in Figure 1) that enough angles carry out trigger sensor 13 so that cam 15 can drive fork 12 to rotate.When isolating switch closes, cam 15 rotates clockwise from the position Fig. 2, thus fork 12 is pivotally rotated, and triggers sensitive switch, and the position entering Fig. 1 closes auxiliary switch.When isolating switch disconnects, cam 15 turns to the position of Fig. 2 from the inverse position hour hands of Fig. 1, thus finishes to be disconnected by isolating switch the triggering of sensitive switch, and the contact 131 of sensitive switch gets back to its original position by impelling fork 12 in the process.According to one embodiment of the present invention, housing 11 can have a guide groove 16, and the other end 18 of fork 12 can slide in guide groove 16.It will be appreciated by those skilled in the art that, although the auxiliary switch 1 that Fig. 1 and Fig. 2 shows has two forks 12 and transducer 13, its cam 15 is positioned at the inner side of two forks 12, and transducer 13 is positioned at the outside of two forks 12, but also can only use a fork 12 according to actual needs, and a transducer 13 and cam 15 lay respectively at the both sides of fork 12.Now, fork 12 only can have a flange.
Fig. 3 and Fig. 4 schematically illustrates the auxiliary switch 2 according to the second execution mode of the present invention, and wherein auxiliary switch 2 is in open position in figure 3, and is in trigger position in the diagram.Auxiliary switch 2 has the housing 11 same with auxiliary switch 1, fork 12, transducer 13.One end 17 of fork 12 is same and housing 11 is fixing, and its other end 18 can move within the specific limits.Be different from auxiliary switch 1, auxiliary switch 2 at the position of sound production of groove 14 (see Fig. 1 and Fig. 2) as the projection 24 of actuator.Fork 12 is between transducer 13 and projection 24.Wheel 25 can rotate with the driving mechanism of driving stage 3, but does not have the flange that cam 15 has, and fork 12 therefore can not be made to rotate.Transducer 13 is still positioned at the side of fork 12, and projection 24 is positioned at the opposite side of fork 12.Cutaway view Z-Z schematically illustrates projection 24 and is arranged on state in auxiliary switch 2, is wherein provided with spring 29 between projection 24 and housing 11.When projection 24 is subject to external force (as shown in Figure 4), spring 29 will be compressed.
Fig. 5 illustrates the stereogram of projection 24, and wherein projection 24 comprises two the second flanges 243 (illustrate only one of them in figure), small boss 244, small boss 245, first push rod 241 and the second push rod 242 that are arranged symmetrically with.Two flanges 243 coordinate the first flange 121 (see Fig. 1 and Fig. 2) on fork 12 respectively, and small boss 244 and small boss 245 are positioned in spring 29.First push rod 241 and the second push rod 242 are perpendicular to the primary flat of housing 11, and the first push rod 241 coordinates the projection 31 and protruding 32 of drive rod 30, and the second push rod 242 coordinates the projection 33 of drive rod 30.When implementing test function, driving the second push rod 242 to press down projection 24 by protruding 31 or protruding 32, and when implementing first to divide function, driving the first push rod 241 to press down projection 24 by protruding 33.Subsequently, the second flange 243 of projection 24 will correspondingly press down the first flange 121 of fork 12, thus drive fork 12 to rotate, and the other end 18 of fork 12 is separated laterally, and then trigger sensor 13.It will be appreciated by those skilled in the art that, although the auxiliary switch 2 that Fig. 3 and Fig. 4 shows has two forks 12 and transducer 13, projection 24 is positioned at the inner side of two forks 12, and transducer 13 is positioned at the outside of two forks 12, but also only can use a fork 12 and a transducer 13 according to actual needs, projection 24 only has second flange 243.
Fig. 6 illustrate the drive rod 30 that coordinates with the projection 24 of the second execution mode of the present invention and on projection 31, protruding 32 and protruding 33.The projection 24 that Fig. 7 illustrates the second execution mode of the present invention with the coordinating of drive rod 30, wherein eliminate the housing of driving stage 3, and illustrate contact 131 and the contact pin 132 of transducer 13 in Fig. 1 to 4.The auxiliary switch 2 that Fig. 8 shows the second execution mode of the present invention joins individual assembly drawing with driving stage 3.
Fig. 9 illustrates coordinating of projection 24 and drive rod 30 when implementing test function by drive rod 30.When drive rod 30 transforms to state B (namely pointer forwards Test to by Off) by state A, the first push rod 241 is subject to the power transmitted by protruding 33, thus promotion fork 12 triggers sensitive switch, and closed auxiliary switch.
Figure 10 illustrates coordinating of projection 24 and drive rod 30 when implementing first point function by drive rod 30.Being transformed to by state C at drive rod 30 can through a centre position (namely shape reads D) in the process of state E (namely pointer forwards Off to by On), second push rod 242 is subject to the power transmitted by protruding 32 at state C, thus promotion fork 12 triggers sensitive switch, and closed auxiliary switch; When drive rod 30 rotate counterclockwise about 60 degree transform to state D time, the driving mechanism of driving stage 3 arrives dead point.Now, projection 24 lifts, and auxiliary switch disconnects, and isolating switch not yet disconnects.When drive rod 30 arrives state E, the actual disconnection of isolating switch; When isolating switch closes (pointer forwards On to by Off), drive rod 30 transforms to state C by state E.Now, the driving mechanism of driving stage 3 is actual behind arrival dead point disconnects.By first point function can judge the contact of auxiliary switch disconnect and the contact of contact pole disconnect between time difference whether in 20ms, and the contact of auxiliary switch whether with the contact of contact pole simultaneously or be later than the contact closure of contact.
Although more than illustrate embodiments of the present invention, described execution mode is not intended to show all possible form of the present invention.In addition, the content in this specification is descriptive, and nonrestrictive.Those skilled in the art can make variations and modifications to the content of this specification, and do not depart from the scope of purport of the present invention and claim.
