Description
Technical field:
The utility model relates to resistor proving installation technical field, specifically U-shaped low resistance precision resistor testing jig.
Background technology:
The resistance of low resistance precision resistor is less, precision is higher, when measuring low resistivity value resistor, if still adopt two traditional end method of testings can produce very big error, the lower error of resistance is larger, this is because the existence of the lead-in wire of contact resistance itself and lead end point cantact resistance. on the impact of measurement result.In order to eliminate the impact of additional resistance on measurement result, we generally adopt the double bridge of four ends to be used for the low resistivity value resistor of measurement less than 1 ohm; And low resistivity value resistor also make four ends draw, resistor also make every limit have current terminal and voltage end easy to use.A kind of U-shaped low resistivity value resistor is the resistor of monolateral extraction low resistance.The test and comparison trouble of this product, resistor exit spacing only has 7mm, and four fixtures are not easy to clamp to test.
Utility model content:
Technical problem to be solved in the utility model is to provide a kind of easy to use, and test is easy, the U-shaped low resistance precision resistor testing jig that measuring accuracy is high.
Solve technical matters adopt following technical scheme:
A kind of U-shaped low resistance precision resistor testing jig, it is characterized in that: comprise base plate, cylinder, insulating support, test electrode and insulating supporting pad, described cylinder comprises 2, symmetrical and the output terminal top being arranged on base plate in opposite directions of cylinder, described insulating support comprises 2 and is separately positioned on the output end of 2 cylinders, described test electrode is separately positioned on insulating support, each insulating support is provided with 3 test electrodes on above-below direction, described insulating supporting pad be fixed on base plate top and between test electrode on 2 insulating supports.
One end of described insulating supporting pad is set to circular arc, and two side positions of the insulating supporting pad opposite end being provided with circular arc are provided with draw-in groove.The external structure of insulating supporting pad and the inside structure of U-shaped low resistance precision resistor match, and fixing of U-shaped low resistance precision resistor is more reliable and more stable, is convenient to test.
Make test electrode tightly push down the electrode of resistor during cylinder operation, resistor has the fixing of insulating supporting pad and supports, and can not produce distortion.Each insulating support is provided with 3 test electrodes on above-below direction, be positioned at the electrode for electric current exit of both sides, centre is the electrode of voltage leading-out ends.
The beneficial effects of the utility model are: the utility model is simple and reasonable, easy to use, and easily, measuring accuracy is high in test.
Accompanying drawing illustrates:
Fig. 1 is that the utility model coordinates main TV structure schematic diagram with U-shaped low resistance precision resistor.
Fig. 2 is the left TV structure schematic diagram of the utility model Fig. 1.
Embodiment:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, 2, a kind of U-shaped low resistance precision resistor testing jig, comprise base plate 1, cylinder 2, insulating support 3, test electrode 4 and insulating supporting pad 5, cylinder 2 comprises 2, symmetrical and the output terminal top being arranged on base plate 1 in opposite directions of cylinder 2, insulating support 3 comprises 2 and is separately positioned on the output end of 2 cylinders 2, test electrode 4 is separately positioned on insulating support 3, on each insulating support, 3 are provided with 3 test electrodes on above-below direction, insulating supporting pad 5 be fixed on base plate 1 top and between test electrode 4 on 2 insulating supports 3.One end of insulating supporting pad 5 is set to circular arc, and two side positions of insulating supporting pad 5 opposite end being provided with circular arc are provided with draw-in groove.U-shaped low resistance precision resistor 6 just blocks and in the outside of insulating supporting pad 5, when cylinder 1 drives test electrode 4 to clamp U-shaped low resistance precision resistor 6, test electrode 4 just with the electrode contact of U-shaped low resistance precision resistor 6.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
