Abstract
The utility model relates to an insulator. Specifically say, be vacuum switch with operating device between be connected the insulator of usefulness. It includes there is the full skirt by the column body on the column body excircle. Even there is the connecting rod at column body lower extreme center. Its structural feature is that column body upper end has the axial cavity, is had contact spring and separation blade outward in proper order by the lining in the axial cavity, and axial cavity oral area is fixed with the apron, and there is the pole hole at the apron center. The separation blade is circular, and there is a plush copper at its lateral surface center, the protrusion was outside the apron after the pole hole was passed to the plush copper. Adopt this kind of insulator, the whole vacuum contactor's of reducible height and volume make vacuum contactor satisfy industry standard.
Description
Technical field
The utility model relates to a kind of assembly of appliance switch.Specifically, be the insulator be connected between vacuum switch with operating mechanism.
Background technology
In the electrical apparatus, for ease of operating vacuum contactor, between the moving conductive rod and operating mechanism of vacuum switch tube, be all provided with insulator.Insulator is wherein traditional insulator, this conventional insulators comprises a cylindrical body, described group of shape body is solid construction, its cylindrical is processed with full skirt, cylindrical body lower center is connected with the connecting rod be connected with the connecting lever of operating mechanism, on connecting rod, cover has touch spring, and both ends of the spring offsets with the connecting lever of cylindrical body lower end and operating mechanism respectively.Because described touch spring is enclosed within connecting rod, make the length of connecting rod longer, thus make that the height of whole vacuum contactor is higher, body is larger.And electric clearance and creepage distance must meet industry standard, the height one of whole vacuum contactor is high, volume one is large, just cannot meet industry standard.
Utility model content
Problem to be solved in the utility model is to provide a kind of insulator.Adopt this insulator, height and the volume of whole vacuum contactor can be reduced, make vacuum contactor meet industry standard.
Problem to be solved in the utility model is realized by following scheme:
Insulator of the present utility model comprises cylindrical body, and cylindrical body cylindrical has full skirt.Cylindrical body lower center is connected with connecting rod.Its design feature is that cylindrical body upper end has axial cavity, and by inner and have touch spring and catch successively outward in axial cavity, axial cavity oral area is fixed with cover plate, and cover plate central has rod aperture.Described catch is circular, and there is plush copper at its lateral surface center, and described plush copper is protruded outside cover plate through after rod aperture.
As can be seen from the above scheme, because cylindrical body upper end is processed with axial cavity, touch spring is arranged in axial cavity, becomes on connecting rod that traditional touch spring is enclosed within cylindrical body lower center as touch spring is enclosed within cylindrical body.So, the length of connecting rod is substantially reduced.And the contraction in length of connecting rod, add that touch spring does not need to be enclosed within connecting rod, greatly reduce again height and the volume of whole vacuum contactor, make vacuum contactor to meet industry standard.
Accompanying drawing explanation
Fig. 1 is insulator structure schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, insulator of the present utility model comprises a cylindrical body 7, and cylindrical body 7 cylindrical is processed with full skirt 8.Cylindrical body 7 upper end is processed with axial cavity, makes cylindrical body 7 for hollow structure.By inner and outer touch spring 9 and the catch 6 of being provided with successively in axial cavity, axial cavity oral area is fixed with cover plate 3 by screw 2, and cover plate 3 center is processed with rod aperture.Described catch 6 is circular, in being slidably matched between the chamber wall of its cylindrical and axial cavity.The lateral surface center of catch 6 is processed with plush copper 5, and described plush copper 5 is protruded outside cover plate 3 through after the rod aperture on cover plate 3.Described plush copper 5 is connected with guide post 4.Under using state, the moving conductive rod overhanging end of described guide post 4 and the vacuum switch tube above it offsets.
Cylindrical body 7 lower end is processed with circular lower convexity 1, makes at the bottom of the chamber of axial cavity thicker.Described cylindrical body 7 lower end is provided with connecting rod 10, and one end of connecting rod 10 is embossed in Qiang Di center.Under using state, the other end of connecting rod 10 is connected with the operation connecting lever of vacuum contactor by pin.
The utility model is enclosed within cylindrical body 7 by the connecting rod 10 that traditional touch spring 9 is enclosed within cylindrical body 7 lower center changes touch spring 9 into, substantially reduce the length of connecting rod 10, reduce height and the volume of whole vacuum contactor, make vacuum contactor to meet industry standard.
