Abstract
The utility model relates to a glass mercury conductive switch, comprising a glass shell, an electrode wire and a mercury. The electrode wire is made of a dumet wire and the glass shell is made of ordinary electronic glass. The surface of the mercury contacts the electrode wire and thereby, the 'switching on ' or the 'switching off ' of a circuit can be determined. The utility model has the advantages of low price, convenient use and wide purpose and is widely used for circuits of devices of textiles, lathes, children toys, automatic alarm, etc.
Description
The utility model relates to glass mercury conductive switch, particularly relates to a kind of Automatic Control Component in the automated system.
Existing glass mercury conductive switch, the cost height, electrode when welding, and pack tightly through too small thin metal material, zinc-plated then, welding again, the most of usefulness of electrode be the tungsten bar, the switch that produces as Nanjing, with regard to usefulness be the tungsten bar, handle quite trouble.The glass shell that the switch that produce in price height and Nanjing is used is tungsten group glass or No. 11 material, and cost is also very high.
The purpose of this utility model is a kind of mercury conductive switch that uses new material as electrode of design, and cost is reduced, and is convenient to extensive use.
The purpose of this utility model realizes by following proposal.Glass mercury conductive switch of the present utility model, by glass shell, electrode and mercury are formed, and it is characterized in that electrode material is a Dumet wire, and glass are ordinary electronic glass.In addition, the electrode of mercoid switch can be the two poles of the earth, also can be three utmost points, or multipole.Glass shell can be column type, and is curved, or designs the glass shell of arbitrary shape as required.
Describe glass mercury conductive switch of the present utility model in detail below in conjunction with description of drawings.
Fig. 1 is the structure chart of the two poles of the earth of the present utility model glass mercury conductive switch;
Fig. 2 is the structure chart of three utmost point glass mercury conductive switchs of the present utility model.
In the two poles of the earth glass mercury conductive switch shown in Figure 1, comprise glass shell (1), two electrodes (2) and mercury (3).Mercury (3) is packed in the glass shell (1), and two electrodes are to insert in the glass shell (1), when switch is worked, the connection of connecting with power supply and load of two electrodes, when mercoid switch was in a kind of displacement angle, mercury was connected two electrodes, thereby entire circuit is connected, when mercoid switch recovered original angle, mercury disconnected two electrodes, so glass mercury conductive switch plays the effect of " leading to " or " breaking ".
In three utmost point glass mercury conductive switchs shown in Figure 2, comprise glass shell (1), three electrodes (4) and mercury (3).Mercury (3) is packed in the glass shell (1), and three electrodes are to insert in the glass shell (1).When switch is worked, the connection of connecting with power supply and load of three electrodes, when the mercoid switch shift in position, mercury (3) is connected electrode (4), thereby entire circuit is connected.
Electrode material in above-mentioned Fig. 1 and the glass mercury conductive switch illustrated in fig. 2 is a Dumet wire.Glass shell is an ordinary electronic glass.Glass shell (1) can be a column type ' long curved or be designed to arbitrary shape as required.
During use, according to different practical working situation, as voltage, electric current, resistance etc., only change the diameter of electrode material, the length of pole span and glass shell, thickness can reach different purposes.
Glass mercury conductive switch of the present utility model, design voltage V≤220V, electric current I≤15A, contact resistance are 0.01 Ω-2 Ω.
The glass shell mercury conductive switch scope of application is wide, can be widely used in the apparatuses such as weaving, lathe, toy for children, automatic warning, and cheap, easy to use.
Claims (3)
1, a kind of glass mercury conductive switch, constitute by glass shell (1), electrode (2), mercury (3), it is characterized in that, glass shell is an ordinary electronic glass, electrode (2) is the Dumet wire material, mercury (3) is positioned among the glass shell (1), and electrode (2) is inserted in the glass shell (1).
2, glass mercury conductive switch according to claim 1, it is characterized in that: glass shell is column type or curved.
3, glass mercury conductive switch according to claim 1 is characterized in that: electrode can be two, three or many.
