On.Boss 242 has guiding surface 2421 close to the end of button 231.When auxiliary switch 2 is in the release conditions shown in Fig. 5,
Now push rod 24 is in first position, and the button 231 of boss 242 (guiding surface 2421) and microswitch 23 is separated.
For the motion process of clear explanation push rod 24, Fig. 5, which is shown, is used for the drive of driving push rod 24 in breaker of plastic casing 1
Lever 13.The end of drive rod 13 is in contact with one end of the adjutage 244 of push rod 24, and wherein drive rod 13 can be by plastic housing
The rotary motion of the devices such as tripping or live spindle (Fig. 5 is not shown) in breaker 1 is converted to the actuator of linear motion.
Describe the handoff procedure of the on off operating mode of auxiliary switch 2 in detail below in conjunction with accompanying drawing.
After the mechanism such as the tripping in breaker of plastic casing 1 or live spindle rotates along a direction, drive rod 13 is driven
Linear motion, drive rod 13 promotes one end of the adjutage 244 (shown in Figure 3) positioned at first position push rod 24 along push rod 24
Be axially facing in stage clip motion process, the guiding surface 2421 of boss 242 first is in contact with button 231；Then boss 242
The button 231 of microswitch 23 is pressed, while the compression press spring 25 of collar flange 241 makes its energy storage；Finally, when drive rod 13 is promoted
The adjutage 244 of push rod 24 (is described in detail) when moving predetermined distance to the second place below in conjunction with Fig. 6 and 7, boss 242
The button 231 of microswitch 23 is compressed, and triggers it, while stage clip 25 is in compressive state and completes energy storage.
Fig. 6 is schematic perspective view of the auxiliary switch shown in Fig. 2 in triggering state, and Fig. 7 is the auxiliary switch shown in Fig. 6
After being splitted along the interface of its lid and housing, the sectional view in terms of the signified directions of arrow B.As shown in Figures 6 and 7, push rod 24 and
Its adjutage 244 is located at the second place, and adjutage 244 is resisted against the another of notch 2131 (being extended arm 244 in figure 6 to block)
Side.Boss 242 is oppositely arranged with button 231 and compresses button 231 (Fig. 7 is not shown), it is put in microswitch 23, together
When push rod 24 the compression press spring 25 of collar flange 241 make its energy storage.
After the mechanism such as the tripping in breaker of plastic casing 1 or live spindle rotates in the opposite direction, drive rod 13 is driven
Adjutage 244 away from push rod 24 is moved.Now stage clip 25 releases energy during elongation, and promotes the ring-type of push rod 24
Flange 241 so that push rod 24 moves to first position, final boss 242 and microswitch 23 along its axial direction from the second place
Button 231 is separated, and button 231 stretches out from microswitch 23, returns to the release conditions shown in Fig. 5.
The button 231 of push rod 24 and microswitch 23 of the present utility model is oppositely arranged, push rod 24 along its be axially moved when,
The push rod 24 moved along a straight line can be accurately controlled with the gap of microswitch 23 or distance, due to the boss 242 of its side wall
Button 231 is pressed, therefore driving stroke is accurate, can accurately, reliable trigger microswitch 23.Further, since push rod 24 is not
Any active force is applied to the shell of microswitch 23, even if the driving stroke of push rod 24 is excessive, is also avoided that damage fine motion is opened
23 are closed, its service life is extended.
The guiding surface 2421 of boss 242 enables push rod 24 successfully to move to the second place from its first position,
And press button 231.
Collar flange 241 on push rod 24 is easy to a part for stage clip 25 to be enclosed on one end 243 of push rod 24 so that assembled
Journey is simple, and collar flange 241 makes its energy storage for supporting stage clip 25, and pressing stage clip 25 in addition.
Size of the notch 2131 of the present utility model in the axial direction along push rod 24 is equal to push rod 24 in its first position
To the spacing of the second place, the position of the boss 242 of push rod 24 and its side wall so can be further limited, it is ensured that push rod 24 exists
During its second place, boss 242 just presses button 231 to trigger auxiliary switch 2.
There is spacing preiection 2231 and Elastic buckle 2241 so that the installation of auxiliary switch 2 on two limited walls of lid 22
Or dismantle more convenient, the saving assembly or disassembly time.Other auxiliary switch 2 being capable of modular manufacturing, saving manufacturing cost.
Lid 22 and housing 21 of the present utility model are snapped together by the step-like recess and extension being adapted, and enter one
Step improves efficiency of assembling, can reduce the cost of auxiliary switch 2.
In other embodiment of the present utility model, push rod does not have boss, the portion that wherein push rod is oppositely arranged with button 231
It is in round table-like to divide, during push rod moves to the second place from first position, the first contact button of round table-like side wall of push rod
231, button 231 is compressed afterwards, so that auxiliary switch 2 is triggered.
In another embodiment of the present utility model, side wall of the push rod 24 close to one end 243 of stage clip 25 can have
Other shapes of thrust, the thrust, which supports stage clip 25 and presses stage clip 25, makes its energy storage.
In another embodiment of the present utility model, push rod 24 does not have collar flange, and push rod 24 connects with stage clip 25
The diameter of tactile one end is more than the diameter of stage clip 25 so that the end face support of one end of push rod 24 and compression press spring 25.
Although the utility model has been described by means of preferred embodiments, but the utility model is not limited to this
In described embodiment, made various changes and change are also included in the case where not departing from the utility model scope
Change.
