Abstract
The utility model relates to a liquid arcless switch for electrical equipment, belonging to the switch manufacturing field. The utility model is characterized in that the lower end of a cyathiform contacting body (2) is a binding post (1), a column contacting body (5) is positioned in the cyathiform contacting body (2), and an insulating shell (7) is positioned on the cyathiform contacting body (2). The lower segment of the cyathiform contacting body (2) is a minor diameter cup (3), and the upper segment of the cyathiform contacting body (2) is a major diameter cup (4). Conducting liquid (9) is in the lower part of the minor diameter cup (3), and insulating liquid (8) is positioned on the conducting liquid (9). The upper end of the column contacting body (5) is provided with the binding post (6). The liquid arcless switch for electrical equipment has the advantages of rapid contacting action, good conducting capability, no electric arc, long service life, and originative, unique, simple and practical structure design.
Description
The utility model belongs to switch and makes the field.
Background technology of the present utility model is: in circuit, plug-in strip or touch switch because the sheet deformation rough surface often causes loose contact, increase electricity and decrease, and produce electric arc, burn out contact chip, influence the good operation and the life-span of power consumption equipment.
Purpose of design of the present utility model is: avoid weak point of the prior art, design and a kind ofly can contact well, not produce electric arc, do not increase the liquid that electricity decreased and do not burn out switch contact and do not have the arc appliance switch.
Design of the present utility model: this switch mainly is made up of cup-shaped contact (2) and cylindricality contact (5), under cup-shaped contact (2), there is binding post (1) to be connected with circuit, cup-shaped contact (2) is made of hypomere path cup (3) and the big footpath of epimere cup (4) two parts, conducting liquid (as mercury) is arranged at the bottom in path cup (3), there is arc extinguishing oil on top in big footpath cup (4), cylindricality contact (5) upper end has binding post (6) to be connected with circuit, cup-shaped contact (2) rim of a cup upwards, cylindricality contact (5) is perpendicular to directly over the path rim of a cup, but and knee-action.In the time will making open circuit, cylindricality contact (5) is in path cup (3) top, and has part to be immersed in the arc extinguishing oil (8) of big footpath cup (4).Insulation shell (7) bag is assisted on cup-shaped contact (2).In the time will making closing of circuit, cylindricality contact (5) is action downwards, insert in the path cup (3), the arc extinguishing oil that compresses in the cup arrives in the big footpath cup (4) to overflow, when moving down in the conductive liquid, make on the conductive liquid liquid level and move, cylindricality contact (5) immerses in the conductive liquid rapidly times over self responsiveness, path cup (3) wall is contacted by the conductive liquid letter with wall with cylindricality contact (5) bottom surface, thereby make the closing of circuit conducting.
Advantage of the present utility model is, contact action is fast, and the flowability of liquid is not tight to switch contact surface requirements, changes the single face contact and is all contacts, conductive area increases, conductivity improves, and contact has closely overcome closed bad drawback, arc extinguishing oil blast cost is low, the switch long service life, simple in structure, the reliability height.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a closing structure schematic diagram of the present utility model.
Fig. 3 is the structural representation of a kind of embodiment of the present utility model.
1--3 does with narration the utility model in conjunction with the accompanying drawings.
A kind of liquid does not have the arc appliance switch, and the lower end of cup-shaped contact (2) is binding post (1), and cylindricality contact (5) is positioned at cup-shaped contact (2), and insulation shell (7) is positioned on the cup-shaped contact (2).The hypomere of cup-shaped contact (2) be path cup (3), on move and be big footpath cup (4), and conductive liquid (as mercury) (9) is positioned at the below of path cup (3), iknsulating liquid (as arc extinguishing oil) (8) is positioned on the conducting liquid (9).The upper end of cylindricality contact (5) is binding post (6).
Claims (3)
1, a kind of liquid does not have the arc appliance switch, it is characterized in that: the lower end of cup-shaped contact (2) is binding post (1), and cylindricality contact (5) is positioned at cup-shaped contact (2), and insulation shell (7) is positioned on the cup-shaped contact (2).
2, liquid according to claim 1 does not have the arc appliance switch, it is characterized in that: the hypomere of cup-shaped contact (2) be path cup (3), on move and be big footpath cup (4), and conductive liquid (9) is positioned at the below of path cup (3), and iknsulating liquid (8) is positioned on the conducting liquid (9).
3, liquid according to claim 1 does not have the arc appliance switch, it is characterized in that: the upper end of cylindricality contact (5) is binding post (6).
