Embodiment
Fig. 1 and Fig. 2 have showed that schematically wherein auxiliary switch 1 is in the close position, and in Fig. 2, is in open position according to the auxiliary switch 1 of first kind of execution mode of the present invention in Fig. 1.Auxiliary switch 1 comprises housing 11, fork 12, transducer 13 and as the cam 15 of actuator.Housing 11 is processed through injection moulding usually.One end of fork 12 and housing 11 pivotally are connected in axle 17, thereby and can its other end 18 can be moved within the specific limits around axle 17 rotations.For example be positioned at a side of fork 12, and cam 15 is positioned at the opposite side of fork 12 for the transducer 13 of sensitive switch.The contact pin 131 of sensitive switch is pressed against the part near the other end 18 of fork 12.Cam 15 comprises two flanges, and receives the driving mechanism (not shown) of driving stage 3 (see figure 8)s to drive and rotate.When cam 15 rotates on housing 11; Said flange can be resisted against on the side of fork 12; And driving pendulum rod 12 is around axle 17 rotating certain angle pivotally, thereby the contact chip 131 that makes fork 12 trigger sensitive switches to send the signal of telecommunication through contact pin 132 (Fig. 7 only mark 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, so that cam 15 can driving pendulum rod 12 rotate the contact 131 (as shown in Figure 1) that enough angles trigger transducer 13.When isolating switch was closed, the position of cam 15 from Fig. 2 clockwise rotated, thereby fork 12 is pivotally rotated, and triggered sensitive switch, got into the closed auxiliary switch in position of Fig. 1.When isolating switch broke off, cam 15 turned to the position of Fig. 2 from the inverse position hour hands of Fig. 1, thereby be through with isolating switch was broken off in the triggering of sensitive switch, and the contact 131 of sensitive switch will impel fork 12 to get back to its original position in this 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 show has two forks 12 and transducer 13; Its cam 15 is positioned at the inboard 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 transducer 13 and cam 15 lay respectively at the both sides of fork 12.At this moment, fork 12 can only have a flange.
Fig. 3 and Fig. 4 have showed that schematically wherein auxiliary switch 2 is in open position in Fig. 3, and in Fig. 4, is in trigger position according to the auxiliary switch 2 of second kind of execution mode of the present invention.Auxiliary switch 2 has housing 11, fork 12, the transducer 13 same with auxiliary switch 1.One end 17 of fork 12 is same to be fixed with housing 11, 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 (seeing 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 is had, and therefore fork 12 is rotated.Transducer 13 still is positioned at a side of fork 12, and projection 24 is positioned at the opposite side of fork 12.Cutaway view Z-Z has showed that schematically projection 24 is installed in the state in the auxiliary switch 2, wherein is equipped with spring 29 between projection 24 and the housing 11.When projection 24 receives external force (as shown in Figure 4), spring 29 will be compressed.
Fig. 5 has showed the stereogram of projection 24, and wherein projection 24 comprises two second flanges 243 (only showing one of them among the figure), small boss 244, small boss 245, first push rod 241 and second push rod 242 of symmetric arrangement.Two flanges 243 cooperate first flange 121 (seeing Fig. 1 and Fig. 2) on the fork 12 respectively, and small boss 244 is positioned in the spring 29 with small boss 245.First push rod 241 and second push rod 242 are perpendicular to the primary flat of housing 11, and the convexity 31 and convexity 32 of first push rod, 241 cooperation drive rods 30, and second push rod 242 cooperates the convexity 33 of drive rods 30.When implementing test function, drive second push rod 242 through protruding 31 or protruding 32 and press down projection 24, and when implementing to divide function earlier, drive first push rod 241 through protruding 33 and press down projection 24.Subsequently, second flange 243 of projection 24 will correspondingly press down first flange 121 of fork 12, thereby driving pendulum rod 12 rotations make the other end 18 of fork 12 separate laterally, and then trigger transducer 13.It will be appreciated by those skilled in the art that; Although the auxiliary switch 2 that Fig. 3 and Fig. 4 show has two forks 12 and transducer 13; Projection 24 is positioned at the inboard of two forks 12; And transducer 13 is positioned at the outside of two forks 12, but also can only use a fork 12 and a transducer 13 according to actual needs, and projection 24 only has one second flange 243.
Fig. 6 showed the drive rod 30 that cooperates with the projection 24 of second kind of execution mode of the present invention and on convexity 31, protruding 32 and protruding 33.The projection 24 that Fig. 7 has showed second kind of execution mode of the present invention with the cooperating of drive rod 30, wherein removed the housing of driving stage 3, and showed the contact 131 and contact pin 132 of transducer 13 among Fig. 1 to 4.The assembly drawing that the auxiliary switch 2 that Fig. 8 has shown second kind of execution mode of the present invention and driving stage 3 are joined.
Fig. 9 has showed cooperating of projection 24 and drive rod 30 when implementing test functions through drive rod 30.When drive rod 30 transformed to state B (being that pointer forwards Test to by Off) by state A, first push rod 241 received the power of transmitting by protruding 33, triggered sensitive switch thereby promote fork 12, and closed auxiliary switch.
Figure 10 has showed cooperating of projection 24 and drive rod 30 when implementing branch function earlier through drive rod 30.Being transformed to by state C at drive rod 30 can be through a centre position (being that shape is read D) in the process of state E (being that pointer forwards Off to by On); Second push rod 242 receives the power of transmitting by protruding 32 at state C; Thereby promote fork 12 and trigger sensitive switch, and closed auxiliary switch; When drive rod 30 rotates counterclockwise about 60 degree when transforming to state D, the driving mechanism of driving stage 3 arrives the dead point.At this moment, projection 24 has lifted, and auxiliary switch breaks off, and isolating switch does not break off as yet.When drive rod 30 arrives state E, the actual disconnection of isolating switch; When isolating switch is closed (pointer forwards On to by Off), drive rod 30 transforms to state C by state E.At this moment, the driving mechanism of driving stage 3 actual disconnection after arriving the dead point.Through first branchs function can judge that the contact of auxiliary switch breaks off and the time difference of the contact of the contact utmost point between breaking off whether in 20ms, and whether the contact of auxiliary switch with contact while of the contact utmost point or be later than the contact closure of contact.
Although more than showed execution mode of the present invention, said 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.
