Detailed Description
The present invention will be further explained with reference to the accompanying drawings: as shown in the figure, the micro-switch device of the automatic transfer switch comprises a shell 1 installed on a shell 9 of the automatic transfer switch, a micro-switch 2 is arranged in the shell, and the micro-switch device further comprises a push rod 3 matched with the micro-switch, wherein the part of the push rod is arranged in the shell, and the part of the push rod is arranged outside the shell and is arranged opposite to a drive rod 91 on a contact frame 90 of the automatic transfer switch. Be equipped with the contact frame in the shell and be used for the front and back activity to realize breaking apart, this actuating lever is connected with the contact frame, promotes the catch bar when the contact frame activity then touches micro-gap switch through the catch bar, adopts through modular casing installation micro-gap switch, and dustproof effectual and convenient assembling, on the other hand, because the mounting screw is the casing rather than micro-gap switch, be difficult to damage micro-gap switch. The inner wall of the shell forms a relatively closed space, and only the through groove can be arranged for the movement of the push rod.
In this embodiment, the housing is removably attached to the housing by fasteners 92, as shown. The shell can be provided with a mounting hole 10 and is connected with the shell through the mounting hole and a screw, so that the screw is fixedly applied with force on the shell instead of the microswitch, and the microswitch is prevented from being out of work due to larger stress.
In this embodiment, the housing includes a base 11 and a cover 12 that are removably attached, as shown. The base and the upper cover can be disassembled to install the micro switch, and assembly is facilitated.
In this embodiment, as shown in the figure, the base is provided with a retaining ring 111, and the upper cover is provided with a clamping block 120 which is in clamping fit with the retaining ring. What adopt between upper cover and the base is the block structure of buckle and buckle, and is further to the upper cover can carry on spacingly to the micro-gap switch up end.
In this embodiment, as shown in the figure, the upper cover is provided with a positioning pin 121, and the micro switch is provided with a positioning hole 21 matched with the positioning pin. The locating pin can be 2, all set up the locating hole on every micro-gap switch and carry out spacing can it.
In this embodiment, as shown in the figure, the upper cover is provided with a guiding rib 122, and the pushing rod is provided with a guiding groove 31 which is in sliding fit with the guiding rib. The pushing rod is more stable in the moving process and better in using effect.
In this embodiment, as shown in the figure, an elastic member 13 for restoring the push rod is provided in the housing. The pushing rod used after the driving rod returns can be a spring, an elastic sheet and the like.
In this embodiment, as shown, the push rod side wall is provided with a groove 32, the microswitch comprises a button 22, and the push rod comprises a first position where the side wall pushes the button and a second position where the button is disposed in the groove. The lateral wall promotes the action of button, and then when button and recess were to last, the button stretches out under the effect of self spring, and the switching of two positions plays the effect of block micro-gap switch.
