Description
Technical field
The present invention relates to potentiometer, especially a kind of dual-channel potentiometer with switch.
Background technology
Slim potentiometer is widely used in sound equipment, broadcast receiver, vehicle-mounted audio-visual equipment etc.There is following deficiency at least in traditional slim potentiometer:
One of which, traditional slim potentiometer (like 12 types), belt switch, but have only a sound channel.
Its two, another kind of traditional slim potentiometer (like 1001 types) is dual track, but is not with mechanical switch.
Its three, knob turn very flexible, knob rocks during turn, is prone to rub with the notch of installation site, even influences the stability of electric property.
Its four, useful life is short.
Its five, inconvenient installation when the client uses, after potentiometer is assembled on the circuit board, also needs with screw a knob and fastening can the use of axle.
The potentiometer of a kind of thin tape Switching Two of market demand sound channel.
Summary of the invention
The present invention is intended to overcome the above-mentioned deficiency and the market demand of prior art, releases a kind of thin dual-channel potentiometer with switch, and the knob turn is flexible, during turn knob rock minimum, long service life, knob installs, no longer bothers the client that knob is installed.
For this reason, thin dual-channel potentiometer with switch of the present invention adopts following technical scheme:
Construct thin dual-channel potentiometer with switch of the present invention, comprise potentiometer unit and switch element;
The potentiometer unit comprises the terminal of knob, folding mover, output resistance, resistor disc, supporting plate, axle, body and the snap ring of printed circuit on it; Terminal is riveted on resistor disc and connects one to one with the end points of circuit on it;
Switch element comprises switch left end sheet, switch right-hand member sheet, transfer strip, spring, flange and card.
Also have:
Folding is shaped on two brushes on the mover, two said brushes respectively with resistor disc on circuit contacts to export two groups of variable resistors, can regulate and control two sound channels simultaneously;
Be shaped on the multidiameter in big footpath position, the stage casing concentric of said axle; Body is the short cylinder shape, and the through hole of system is opened in the centre that the multidiameter in said big footpath is arranged in the body upper surface, and said axle is opened the through hole of system from the centre that the multidiameter in said big footpath up passes supporting plate, resistor disc and folding mover successively; The upper end of said axle is flat and is installed on the flat hole that system is opened in the knob centre; And the upper end of said axle and knob riveted joint are fastening, and said axle is with knob; Simultaneously, the folding mover is riveted on the downside of knob, and supporting plate pastes and clamping with resistor disc mutually, and the upper surface of body and supporting plate clamping are fastening, and snap ring is stuck in the lower portion of multidiameter in said said big footpath.
Technique scheme is further set forth:
Switch left end sheet, switch right-hand member sheet are riveted on respectively in the body, and they stretch out with the foot that the circuit board of use object is connected; Transfer strip keeps in touch with switch right-hand member sheet and can on the face vertical with said axle, rotate; Be shaped on a projection on the flange and make flange be cam-like,, on flange, have the flat via hole, the lower end of said axle is flat and is installed on the flat via hole on the flange, and flange is rotated with said axle; Projection on the flange and transfer strip activity against, an end of spring is connected with the region of interest of switch right-hand member sheet, the other end of spring is connected with transfer strip; Card is close to the downside of flange and is stuck in the lower end of said axle.When said axle rotated, flange under the acting in conjunction of flange rotation friction and spring torsion, rotated transfer strip along with rotation, causes transfer strip to contact or disengage with switch left end sheet, thereby causes switch left end sheet and switch right-hand member sheet to be switched on or switched off.
The present invention compares with prior art; Beneficial effect is: one of which, be shaped on two brushes at folding on the mover; The design mechanical switch has been realized the integration of dual track and mechanical switch, gathers slim (thickness is no more than 12mm), dual track and mechanical switch in one; Aspect slim potentiometer, filled up the vacancy that dual track and mechanical switch combine.Its two, the upper end of said axle is fastening with the knob riveted joint, the user is installed on potentiometer of the present invention after the circuit board, no longer need knob and said axle head be tightened with screw, minimizing installation procedure and saving set-up time, brings convenience to user installation; Simultaneously, for the performance that improves potentiometer provides measure, because rock when some performance of potentiometer such as turn etc. and to install improper relevant with knob.Its three, the upper end of said axle is fastening with the knob riveted joint, makes said upper end be connected more firmly with knob, and is more smooth, rocks, increases useful life when helping reducing turn.Its four, the folding mover directly is installed on the downside of knob, can reduce the thickness of potentiometer, is beneficial to and makes the product attenuation; Simultaneously, be beneficial to and make the brush of folding on the mover good, with the raising electric stability with the circuit contacts of resistor disc.They are five years old; Supporting plate pastes and clamping with circuit wafer mutually, and simultaneously, body pastes and clamping with supporting plate mutually; Make smooth joining of body, supporting plate and circuit wafer be integral body; The ability of resistor disc resistance to deformation is improved, and the brush that is beneficial on the folding mover keeps well contacting with the circuit of resistor disc, also helps the attenuation of potentiometer thickness.Its six, body is short tubular, switch left end sheet, the hidden installation of switch right-hand member sheet wherein make body both as the installation carrier of switch left end sheet, switch right-hand member sheet, play the support body effect of shell again, also help the attenuation of potentiometer thickness.Its seven, potentiometer of the present invention, long service life is the twice of traditional product.Its eight, purposes is wide, is applicable to sound equipment, broadcast receiver, vehicle-mounted audio-visual equipment, device for mobile communication etc.
