Abstract
The utility model relates to an oblique switch. A current conducting lead wire is vertically fixed and sealed in a bottom board by insulating glass. A metal casing with a conical head is welded on the bottom board. Mercury is arranged at the conical head and exactly makes the current conducting lead wire and the metal casing connected. When the inclination of the switch is greater than a certain angle, the mercury rolls off the conical head, and the current conducting lead wire and the metal casing are disconnected, so the mercury acts as a switch. The metal casing is evacuated to form a vacuum chamber, and the performance of the electric appliance is improved. The utility model has non oxidation, zero wear, and explosion prevention, and is an excellent oblique switch.
Description
The utility model relates to a kind of switch, particularly a kind of tilt switch.
Equipment such as household electrical appliances, instrument, instrument need its position not tilt when using sometimes, and its electric current should cut off at once when these equipment run-off the straights.In order to address this problem, a kind of tilt switch is set, and the tilt switch shell that uses at present is glass on equipment, inner utilization ball gravity principle reaches switching function, and Glass breadks easily is dangerous and the angle of inclination is wayward.
The purpose of this utility model is that a kind of shell will be provided is the tilt switch of metal, when it can make the electric equipment run-off the straight electric current is cut off immediately.
The purpose of this utility model is to realize like this.Conductive lead wire is perpendicular in the metal base plate and be insulated glass and seal admittedly, metal shell is the cone-shaped base plate that is welded in, cone angle can be according to tilting to require design, vacuumize in the switch cavity, vacuum degree is greater than 1 * 10-1 handkerchief, and mercury places the cone angle place with conductive lead wire and shell conduction, when switch tilts greater than certain angle, mercury rolls from cone angle, and conductive lead wire and shell open circuit.Because switch contact is in the vacuum, can not cause electric arc when switch conduction and disconnection.
Advantage of the present utility model is to utilize the characteristic that vacuumizes in the conduction of mercury and rollability and the cavity to make switch not have the wearing and tearing non-oxidation.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is the profile that the utility model proposes tilt switch.
Among the figure 1, conductor leading; 2, insulating glass; 3, metal base plate;
4, mercury; 5, metal shell; 6, vacuum chamber;
Insulating glass 2 vertically is encapsulated in conductive lead wire 1 in the circular hole of metal base plate 3 admittedly, metal shell 5 and metal base plate 3 welding, and head is cone, and mercury 4 places the conehead place, and switch inside is vacuum chamber 6 vacuum degrees greater than 1 * 10
-1Handkerchief, when the switch gradient during greater than certain angle mercury 4 roll from conehead, metal shell 5 opens circuit with conductive lead wire 1, when gradient during less than certain angle mercury 4 cone angle of rolling back make conductive lead wire 1 and metal shell 5 conductings.Because the switches conductive contact is in the vacuum chamber 6, makes switch in electric current conducting repeatedly, can not cause electric arc during disconnection, played explosion-proof, as not have wearing and tearing, non-oxidation effect.
Claims (2)
1, a kind of tilt switch, this switch has conductive lead wire, and shell, base plate, mercury are formed, and it is characterized in that the cavity that is encapsulated by shell is a vacuum, conductive lead wire and base plate insulating glass sealed knot.
2, switch according to claim 1 is characterized in that case head is cone-shaped.
