Abstract
The utility model discloses a potentiometer with multiple resistance value changeable output ends, mainly including a resistor body with screws (can also comprises a part whose one section is not provided with the screws), and the electrode of a screw nut matched with the resistor body. The potentiometer with multiple resistance value changeable output ends overcomes the disadvantages that the existing potentiometer can not be provided with multiple resistance value changeable output ends, and is not provided with fixed resistors which are connected in series. The utility model has the advantages of lower fabricating cost, big resistance values, and easy fine adjustment. The potentiometer with multiple resistance value changeable output ends is suitable for occasions where the potentiometer is used.
Description
The utility model is a kind of potentiometer that a plurality of variable resistance outputs are arranged.
Can not surpass a circle when existing general potentiometer is regulated rotation, and can only have one to become the resistance output, when resistance is very big, finely tune very inconvenient.And but the potentiometer of multi-turn rotation also has only one to become the resistance output, and resistance value is difficult to do greatly, and cost is also very high.The change resistance end and the contact area between the resistive element of these two kinds of potentiometers are all very little, and the bad probability of contact will be more greatly when regulating like this.The fixed resistance (also needing other polyphone) that does not have a polyphone on the variable resistor of potentiometer in many occasions.
The purpose of this utility model is to overcome the deficiencies in the prior art, but a kind of potentiometer that has the change resistance output multi-turn rotation of a plurality of any adjustings to change resistance, can go here and there fixed resistance is provided.
The utility model mainly is made up of resistive element and nut electrode.On the resistive element screw thread resistive element to be arranged.The spiral shell button that is complementary with the screw thread resistive element is arranged on the nut electrode, can on the screw thread resistive element, multi-turn rotate, can be parked in the optional position, also can take off from the screw thread resistive element.There is one section to make the nut electrode can't be on the resistive element, like this two of resistive element and the screw resistive element and the junction of no screw resistive element are arranged just is the fixed resistance output at the no screw thread resistive element of last rotation.The screw thread resistive element is the variable resistor part, and no screw thread resistive element then is a fixed resistance.
Illustrate below in conjunction with figure:
Nut electrode 2 can multi-turn rotate on screw thread resistive element 3 among the figure (1), and the contact area between its door is big like this, and it is little to contact bad probability; Also can be used as the transducer that in a fixing turn scope, rotates; When (screw thread) resistance is very big, also fine-tuning like this, also can take off no nut electrode, increase (restriction that maximum number is subjected to screw thread resistive element length) when needing again; Using the variable-resistance while; no screw thread resistive element 4 also can provide a fixed resistance value (the big I of this resistance value is decided by different needs); be well suited for the occasion of most fixed resistances (for example shielding) of on variable resistor, contacting, if do not need this fixed resistance can directly use screw thread resistive element 3.
Shown in figure (2), this variable-resistance equivalent electric circuit is by fixed resistance 5 and variable resistor 6 polyphones.Resistive element is with having the wear-resisting resistance material of making potentiometer and the material of making screw thread easily now.For example can be the existing fixed resistance transformation of the way of producing for having the resistive element of screw thread, then with having conduction, wear-resisting spiral shell button as the nut electrode.
The utility model can be according to different needs, and the series that divides different parameters into is produced in enormous quantities, is widely used in using the occasion of potentiometer.
