Abstract
The utility model relates to a magnetic-coupling linked vacuum switch tube, comprising a glass cover which is formed by sticking two cups and which is provided with a vacuum seal and a shielding sleeve; the movable contact is connected to the outer connection column at one end of the glass cover through soft connection bus wire in the cover; the positioning guide column in the cover is used to limit the movement of the movable contact along the center line of the glass cover; the outer transmission mechanism acts on the magnet out of the glass cover and the magnet in the glass cover through the positioning guide column out of the glass cover, so the magnets are coupled to move along the center line in the glass cover, consequently, the demand that the movable contact can be controlled at the outside of the glass cover is satisfied.
Description
Affiliated field
The utility model relates to a kind of magnetic couplings interlock vacuum switch tube of using magnetic coupling interlock principle.
Background technology
In the prior art, vacuum switch tube is the vacuum protection that ensures moving contact and outside line binding post interlock with bellows, and need are assembled under vacuum environment and the vacuum switch tube of seal bond.
Summary of the invention
The purpose of this utility model is brought the deficiency of rapid wear for the complicated technology of the bellows that solves existing vacuum switch tube, vacuum environment assembling and many places seal bond.Use the magnetic coupling linkage technique for this reason and finish the moving contact break-make and the vacuum requirement of magnetic couplings interlock vacuum switch tube external control inside.
The technical scheme that its technical problem that solves the utility model adopts is: when outside gear mechanism drives the pull bar interlock, the external magnet and the internal magnet coupling linkage of horizontal arm-tie, outside fix guide pillar and outside fix guide pillar front end, coupled magnets drives moving contact, under interior positioning guide column limits, moving in axis along glass shell, cuts conduction and connect.Otherwise, do at outside gear mechanism under the effect of counter motion and compression spring, moving contact under inside and outside positioning guide column limits with decide contact and be connected, conducting under certain pressure has reached the magnetic couplings break-make requirement of vacuum switch tube by external control inside moving contact that link.
The utility model is used the needs that magnetic coupling interlock principle realizes device external control internal actions operating mode.Finish moving contact (6) break-make and do not influence the fixing of outside line binding post (9) by the soft bus (8) that connects.Ensure that by inside and outside positioning guide column (7), (3) moving contact moves along the axis of glass shell in addition.When two cup shape glass shells of casting, outside line binding post (9), (16) are cast as one respectively.Other is provided with vacuum-pumping and sealing and outer protective jacket (13) after the assembling of glass shell shell inner part.
The beneficial effects of the utility model are, use the utility model technical measures and have realized simplification product manufacture and condition, reduce cost of goods manufactured, increase product useful life.
Description of drawings
In conjunction with the accompanying drawings and embodiments the utility model is illustrated:
Fig. 1 is that the utility model is overlooked the general assembly schematic diagram: 1 outside gear mechanism pull bar, 2 horizontal arm-ties, 3 outside fix guide pillars, 4 external magnets, 5 internal magnets, 6 moving contacts, positioning guide column in 7,8 soft bus, the 9 outside line binding posts of connecting, 10 compression springs, 11 decide contact, 12 base plates, 13 vacuum-pumping and sealing and outer protective jacket, 14 glass shells, 15 interior location guide column sleeves, 16 outside line binding posts.
