Description
Technical field
The utility model relates to technical field of electronic components, especially relates to a kind of novel without breakpoint segmented potentiometer.
Background technology
Potentiometer is a kind of conventional electronic devices and components, is widely used on the by-pass cock of various electric equipments, and traditional potentiometer can only be realized the adjusting of current potential in single fixing amplitude at present, can not adapt to multi-level diversified demand.Use in the market general have segmentation fixed resistance value potentiometer and adjustable knob; Mostly segmentation fixed resistance value potentiometer is complicated mechanical structure, utilizes the length of resistance line to decide resistance; Adjustable knob is also is mostly complicated mechanical structure, utilizes contact to touch on different gears, realizes adjusting.But no matter be potentiometer or the following shortcoming of adjustable knob ubiquity:
1. complex structure, complex process, poor reliability;
2. cannot effectively apply resistance and distinguish gear;
3. between switching, easily produce neutral gear, open circuit;
4. the more difficult precise quantification of resistance value ratio.
Summary of the invention
The utility model object is to overcome the deficiencies in the prior art, provides a kind of novel without breakpoint segmented potentiometer.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: without breakpoint segmented potentiometer, comprise PCBA, multiple resistance, golden finger, shell fragment; Described PCBA is provided with two golden fingers that are arranged side by side, and wherein on every golden finger, all offers multiple breakpoints; Described multiple resistance is separately positioned on the breakpoint place of golden finger, wherein between resistance and resistance, connects by the golden finger on PCBA; Described shell fragment is three claw-likes, and this shell fragment is arranged on golden finger top and contacts with golden finger.
As preferably, on described golden finger, breakpoint is 3～6.
As preferably, breakpoint quantity on described two golden fingers is identical and be in staggered distribution.
The beneficial effect that the utility model reaches is: simple in structure, good reliability, realize accurate segmentation resistance by the golden finger being arranged side by side multiple resistance of connecting, each section of resistance is stable, between section and section, there is no open circuit/neutral gear, potentiometer can regulate current potential with different amplitudes, flexible.Not only can work as potentiometer with but also can be used as adjustable knob and use, of many uses.

Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
Fig. 1 is structural representation of the present utility model; Fig. 2 is the utility model resistance serial connection schematic diagram.,, mainly formed by PCBA 3, multiple resistance 5, golden finger 2,4, shell fragment 1 etc. without breakpoint segmented potentiometer in conjunction with Fig. 2 from Fig. 1; Described PCBA 3 is provided with two golden fingers that are arranged side by side 2 and golden finger 4, and wherein golden finger 2 is provided with 3～6 breakpoints 21; On golden finger 4, offer the identical and setting of staggering of breakpoint 21,41 quantity on 41, two golden fingers of 3～6 breakpoints 2,4, and golden finger 2 and golden finger 4 are divided into multistage.Resistance 5 is separately positioned on breakpoint 21,41 places of golden finger 2 and golden finger 4, wherein between adjacent two resistance 5, connect by the golden finger 2 on PCBA 3 and golden finger 4, can, according to resistance needs, set the resistance of different resistances, the Precision determination of resistance the accuracy of each section of resistance.Shell fragment 1 is three claw-likes, and this shell fragment 1 is arranged on golden finger 2 and contacts with golden finger 4 tops and with golden finger 2,4.
Fig. 4 a, 4b are a kind of example structure schematic diagrames of the present utility model.Further known in conjunction with Fig. 4, PCBA 3 is fixed on rotor 6 intracavity bottoms, and wherein rotor 6 bottoms are flexibly connected with side, and rotor 6 is provided with a fixed lever 7, on this fixed lever 7, is fixed with shell fragment 1.The side of rotation rotor 6, thus make fixed lever 7 be with spring plate 1 to move, when shell fragment 1 slides on one section of golden finger 2 and golden finger 4, resistance/gear is constant, shell fragment 1 is skipped after the breakpoint on golden finger 2 and golden finger 4, while entering another section of golden finger, and resistance/gear change (as shown in Figure 3).For guaranteeing, in the process of skipping, not produce breakpoint, design two parallel golden fingers 2,4, staggering in breakpoint 21,41 positions, guarantees that the pin of shell fragment 1 can not drop on breakpoint simultaneously.Thereby realized accurate segmentation resistance, each section of resistance is stable, between section and section, there is no open circuit/neutral gear, and potentiometer can regulate current potential with different amplitudes, flexible.Not only can work as potentiometer with but also can be used as and adjust knob to use, of many uses.
The utility model illustrates embodiment of the present utility model and structure by above-described embodiment; but this patent is not limited to above-mentioned execution mode; all employings and the utility model analog structure are realized all modes of the utility model object, all within protection range of the present utility model.
