Description
Technical field
The utility model belongs to the rheostat in circuit, specifically a kind of Novel sliding rheostat.
Background technology
Slide rheostat is a critical elements in circuit, and it can change the resistance of self by the position of mobile slide plate, thus plays the effect of control circuit.In circuit analysis, slide rheostat both can as a fixed value resistance, also can as a resistance-changing resistor.Traveller many employings cylindrical design of the slide rheostat of existing use for laboratory, can rotate when slide plate slides on traveller, very easily produce the problem of loose contact.
Summary of the invention
The utility model provides a kind of Novel sliding rheostat, solves the problem that existing slide rheostat slide plate easily occurs to loosen in the process of sliding.
The utility model realizes above-mentioned purpose by the following technical solutions:
A kind of Novel sliding rheostat comprises support plate, porcelain cylinder, resistance wire, slide bar, slide slide plate, binding post.
Described support plate is the calabash shaped plate that bottom is connected with two angles, and described support plate is provided with identical two; Described porcelain cylinder and slide bar are established and are connected between two support plates, and described slide bar is connected to the top of support plate, and described porcelain cylinder is connected to the bottom of support plate; Described resistance wire is spirally wound on the outside of porcelain cylinder, and the both sides of the resistance wire of winding are fixed by intercell connector, resistance wire be externally coated with insulating barrier; Described slide slip cap is combined on slide bar, and slide bottom is connected with slide plate, and slide plate bottom is overlapped on the resistance wire of described porcelain cylinder outside winding; The both side ends of described slide bar is connected with binding post respectively, and the intercell connector that described resistance wire both side ends is arranged is connected to binding post.
Preferred described slide bar adopts square column structure, can avoid rotating, ensure that the contact effect of slide plate time slide slides thereon.
The utility model overall structure is simple, easy to use, adopts said structure to make the utility model can keep stable in the process used, improves the stability of surveyed data.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the schematic diagram of support plate.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of Novel sliding rheostat as shown in Figure 1 comprises support plate 1, porcelain cylinder 2, resistance wire 3, slide bar 4, slide 51, slide plate 52, first binding post 61, second binding post 62.
Support plate 1 is as shown in Figure 2 connected with the calabash shaped plate at two angles for bottom, and support plate 1 is provided with identical two.
Porcelain cylinder 2 and slide bar 4 are established and are connected between two support plates 1, and slide bar 4 is connected to the top of support plate 1, and porcelain cylinder 2 is connected to the bottom of support plate 1; Resistance wire 3 is spirally wound on the outside of porcelain cylinder 2, and the both sides of resistance wire 3 are fixed by the intercell connector 31 that can conduct electricity, resistance wire 3 be externally coated with insulating barrier; Slide 51 slip cap is combined on slide bar 4, is connected with slide plate 52 in the bottom of slide 51, and slide plate 52 bottom is overlapped on the resistance wire 3 of described porcelain cylinder 2 outside winding, ensure that the conductivity between slide bar 4 and resistance wire 3; The both side ends of slide bar 4 is connected with the first binding post 61 respectively, and two intercell connectors 31 that resistance wire 3 both side ends is arranged are connected to the second binding post 62.
In this structure, slide bar 4 adopts square column structure, can avoid rotating time slide 51 slides thereon, ensure that the contact effect that slide plate 52 is good.
