In one embodiment, resetting means 150 comprises two reset compression elastic element 151 and two slide blocks 152 that reset; As shown in fig. 1, two compression elastic elements 151 that reset are separately positioned on first housing 112 and second housing 114; Two slide blocks 152 that reset are connected with two compression elastic elements 151 that reset respectively, and contact with the body of rod 121 of actuator 120 under correspondence resets the effect of compression elastic element 151.The compression elastic element 151 that resets can be spring.In one embodiment, the reset center of obstructed part 120 rotations of overdriving of active force that 152 pairs of actuators 120 of slide block apply.
Above-mentioned is the concrete structure of isolating switch 100 among the utility model one embodiment, its practical process of brief description.
Figure 2 shows that the pass closed procedure schematic diagram of isolating switch 100 when normal running among Fig. 1.
Shown in Fig. 2 a, isolating switch 100 is in " ONI " position.
The direction rotating drive part 120 shown in the arrow in Fig. 2 b; When isolating switch 100 turned to position shown in Fig. 2 b, protuberance 123 beginnings on the actuator 120 contacted with the slide block 152 that resets, and at this moment, the protuberance 123 on the actuator 120 and the angle of horizontal line straight line are a.In this process, because sliding part 130 is connected with spring operation means 140 by connector 133, therefore, actuator 120 will impel spring operation means 140 storage power; Simultaneously, thus the protuberance on the actuator 120 123 is about to the slide block 152 that resets is applied active force compression elastic element 151 compressions that will reset.
When isolating switch 100 was rotated further to the position shown in Fig. 2 c, the protuberance 123 on the actuator 120 was b with the angle of horizontal line straight line; In this process, slide block 152 applies active force compression elastic element 151 compression that will reset thereby 123 pairs of the protuberances on the actuator 120 reset; Simultaneously, spring operation means 140 is about to release energy.
Shown in Fig. 2 d, isolating switch 100 finally is in " OFF " position.In this process, spring operation means 140 releases energy, and drives actuator 120 by sliding part 130 and is rotated further; Meanwhile, thus the protuberance on the actuator 120 123 continues that the slide block 152 that resets is applied the active force compression elastic element 151 that will reset further to be compressed.
Need to prove, when the compression elastic element 151 of resetting is compressed, the compression elastic element 151 that resets applies reset torque by the 152 pairs of actuators 120 of slide block that reset, just reset torque is much smaller than the suffered actuating force of actuator 120, therefore, in the aforesaid operations process, the reset torque of resetting means 150 can not have a negative impact.
