Description
Technical field
The present invention relates to a kind of rotary band switch device, particularly a kind of conducting liquid contact rotary band switch.
Background technology
At present, known rotary band switch is a kind of interconnecting devices in the circuit.Effect is to be used for changing wave band or choosing connects different circuit.Like the rotary knob of universal instrument, turning knob realizes surveying the gear shift of voltage, electric current and resistance.The structure of known rotary band switch: single or multiple lift insulation annulus, on radius arc such as insulation annulus, equidistantly punch along the circular arc direction, on these holes, inlay inside metal contact, to the elastic sheet metal of tyre lead solder-joint.The inside metal contact of elastic sheet metal to put in the insulation annulus in, wherein have one longer.Establish an insulation disk in addition in the inside of insulation disk, insulation disk upper edge circumference installs and fixes the metal ring of band protrusion contact knife.After being in place, long inside metal contact contacting metal annulus, the protrusion contact knife of metal ring contacts the inside metal contact of some elastic sheet metals.It is poroid that yi word pattern is processed in the center of circle of insulation disk.The axle of knob also is processed into the yi word pattern stock; Pass the insulation circle disk center yi word pattern poroid after; The metal ring that energy of rotation drives band protrusion contact knife on the insulation disk rotates; Contact knife mechanical friction touches the metal contact of each insulation annulus except that longer metal contact successively, realizes that conversion wave band or choosing connect different circuit.What will pay close attention to here is to change wave band or contact each time, all is a friction process.So the life-span of rotary band switch is not long, can not use for a long time.Also has noise in the use.Since the friction, the time and also the loose contact fault can appear.These are critical defects of known rotary band switch.
Summary of the invention
In order to overcome the technical problem of known rotary band switch mechanical friction, the present invention provides a kind of conducting liquid contact rotary band switch that does not have mechanical friction.
The present invention is directed to the technical problem of known rotary band switch mechanical friction, a kind of improvement technical scheme of essence is provided: the mechanical friction of change hard contact, for conducting liquid does not have the frictional electricity contact.With the rotary band switch is example: as shown in Figure 1, in annular air-tightness seal box (1), built-in annular conductive electrode (2), conducting liquid drip (3), inert gas, metallic seal outer lead (5).Radiuses such as a side lid at annular air-tightness seal box (1) equidistantly punch riveting rivet (4) in the hole along the circular arc direction.The rivet cap of riveting rivet (4) is outside box, and the manufactured head in the annular air-tightness seal box (1) will polish and polish, and is equally flat with the inside of annular air-tightness seal box (1).On outside each rivet (4) cap of annular air-tightness seal box (1), weld electrical lead.Electrical lead on the same rivet of annular conductive electrode (2) (4) head constitutes conducting liquid contact rotary band switch.Axis along annular air-tightness seal box (1) during work inserts axle, and vertically fixedly conducting liquid contacts rotary band switch.Under the effect of gravity, conducting liquid drips (3) always in the bottom of annular air-tightness seal box (1).During use, the same with known rotary band switch, along rotational conducting liquid contact rotary band switch, can realize welding being electrically connected successively of electrical lead on annular conductive electrode (2) and outside any rivet (4) head.
Description of drawings
Fig. 1 is the structure chart of conducting liquid contact rotary band switch of the present invention.
Wherein: 1, annular air-tightness seal box (1), 2, annular conductive electrode (2), 3, conducting liquid drips (3), 4, rivet (4),, 5, metallic seal outer lead (5).
Embodiment
Conducting liquid contact rotary band switch is processing like this.Material is selected the 2mm poly (methyl methacrylate) plate for use, uses the machined into outer radius to be two of the annulus of R4, sign A sheet and B sheet as the R1 inside radius.Material is selected the 2mm poly (methyl methacrylate) plate for use, uses the machined into outer radius to be R1, and inside radius is annulus a slice of R2, sign C sheet.Outer radius is annulus a slice of R4 for the R3 inside radius, sign D sheet.Radius length magnitude relationship: R1 wherein " R2 " R3 " R4.A sheet riveting rivet wherein: choose radius R (R2 " R " R3), along the equidistant punching of circular arc direction (every at a distance from 20 ° of punchings in 180 °, totally 10 Φ 1 holes), the rivet cap is with in the lug plate riveting hand-hole, and inboard manufactured head polishes, and is the same flat with the organic plates of inboard.Assembly technology: get the A sheet and keep flat, the rivet cap is downward, gets C sheet and D sheet, behind the gluing, by being bonded on the A sheet with circle.After cementing, form annular groove between the C sheet on the A sheet and the R2 of D sheet and the R3.The thickness of C sheet and D sheet will guarantee that the annular groove degree of depth is enough to mounting circular ring shape conductive electrode (2).In annular groove, avoid the rivet position, drip three droplet glue, mounting circular ring shape conductive electrode (2), annular conductive electrode (2) material is selected the iron pin for use, and circular arc is consistent with annular groove.Annular conductive electrode (2) is parallel with the A plate inner surface but do not contact, and the gap is little as far as possible between the two.Spile near annular conductive electrode (2) end points at the C sheet equally, metallic seal outer lead (5) is installed.Weld firm back with glue sealed aperture and pad.Between annular conductive electrode (2) and A sheet, splashing into mercury metal drips.Mercury metal does not corrode the annular conductive electrode (2) of iron.Because the gap between annular conductive electrode (2) and the A sheet is very little, mercury metal drips the electrical connection that can both realize between rivet and the annular conductive electrode (2).At last, inspection annular conductive electrode (2) highly is not higher than the degree of depth of annular groove, and gluing on C sheet D sheet is stained with the B sheet, looping airtight sealing box (1) then.After checking that the air-tightness of annular air-tightness seal box (1) is qualified,, spile at annular air-tightness seal box (1), bleed inert gas injecting, sealing again.After checking annular air-tightness seal box (1) sealing once more, conducting liquid contact rotary band switch is made successfully.
Method for using: the axis along annular air-tightness seal box (1) inserts axle, and vertically fixedly conducting liquid contacts rotary band switch.Under the effect of gravity, conducting liquid drips (3) always in the bottom of annular air-tightness seal box (1).During use, the same with known rotary band switch, along rotational conducting liquid contact rotary band switch, can realize welding being electrically connected successively of electrical lead on annular conductive electrode (2) and outside any rivet (4) head.
The beneficial effect of conducting liquid contact rotary band switch of the present invention is no mechanical contact, does not have friction that use noiselessness, the life-span is long, and is of many uses etc.Owing to exist gravitational action of gravity, conducting liquid contact not to have the friction rotational potentiometer when vertically installing, also can be used as obliquity sensor, shock sensor, liquid level sensor etc. in addition.
