Description
Technical field
The utility model is related to graphite resistance rate detection field, more particularly, to a kind of test for measuring graphite resistance rate
Frame.
Background technology
In the utilization of graphite product, resistivity is one of important indicator of graphite product quality, when graphite product dispatches from the factory,
For the requirement of different user, Resistivity testing is very important, and often used to be resistivity automatic analyzer to detect
The resistivity of graphite, in measurement, the broken end of probe is very thin, often uneven with graphite contact, so the result meeting measuring
There is very big error, and when detecting, need two to three people to assist, just can complete the process detecting, cause the one-tenth of personnel
This, accuracy rate is not also high.
Utility model content
The purpose of this utility model is to avoid the deficiencies in the prior art, it is to avoid waste of manpower, and detection error is big, and provides
A kind of testing jig for measuring graphite resistance rate, the utility model eliminates manpower, and can realize measurement result more
Accurately.
The purpose of this utility model is achieved by the following measures: a kind of test for measuring graphite resistance rate
Frame, including probe, framework and wire, described probe includes current probe, current probe, voltage probe, voltage probe
, one end of four described probes is each provided with copper mesh, and the other end is respectively connected with the wire for connecting analyzer, institute
The framework stated is the framework that two block length shape iron plate laid parallels are welded in one, and leaves gap in the middle of two pieces of iron plates, framework
Bottom is provided with footing, and four described probes are individually fixed on framework.
A kind of above-mentioned testing jig for measuring graphite resistance rate, described framework is fixed with electric current from top to bottom successively
Probe, voltage probe, voltage probe, current probe.
A kind of above-mentioned testing jig for measuring graphite resistance rate, described probe is screwed on framework,
Wherein current probe is fixed in the gap of framework by screw activity.
A kind of above-mentioned testing jig for measuring graphite resistance rate, described copper mesh is by being fixedly welded on probe one
End.
A kind of above-mentioned testing jig for measuring graphite resistance rate, described copper mesh is oblong-shaped.
A kind of above-mentioned testing jig for measuring graphite resistance rate, described footing is welded as star for three block length shape iron plates
Shape.
A kind of above-mentioned testing jig for measuring graphite resistance rate, described footing vertical welding is in framework bottom.
The beneficial effects of the utility model are: the utility model by the utility model by probe is fixed on framework,
Eliminate manpower, and copper mesh is provided with probe and preferably can contact with graphite, measurement result is more accurate.
Brief description
Fig. 1 is a kind of structural representation of the testing jig for measuring graphite resistance rate.
In figure: 1- framework, 2- wire, 3- current probe, 4- voltage probe, 5- voltage probe, 6- current probe,
7- copper mesh, 8- footing.
Specific embodiment
In order to deepen, to understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model to be made further
Describe in detail.
Embodiment 1: as shown in figure 1, a kind of testing jig for measuring graphite resistance rate, including probe, framework 1 and wire
2, described probe includes current probe 3, current probe 6, voltage probe 4, voltage probe 5, and four probes are according to electricity
Stream probe 3, voltage probe 4, voltage probe 5, the order of current probe 6 are successively in the position peace from top to bottom of framework
Dress, the distance between voltage probe 4, voltage probe 5, current probe 6 are fixing, and it is solid that these three probes pass through screw
It is scheduled on framework, distance is fixed, when measuring graphite without the distance measuring two voltage probes again；Framework 1 is two block lengths
Shape iron plate laid parallel is welded in the framework of one, and leaves gap in the middle of two pieces of iron plates, and current probe 3 is by screw activity
It is arranged in gap, current probe 3 can be gone up downward gap and slide adjustment, the height according to graphite is adjusting this probe
Highly, a lot of troubles are saved, more convenient during detection；One end of four probes is each provided with copper mesh 7, and it is solid that copper mesh 7 passes through welding
Due to probe one end, copper mesh is oblong-shaped, and the other end is respectively connected with the wire 2 for connecting analyzer, by probe
The copper mesh of upper connection can increase the contact area with graphite, and contact can evenly, and the result of detection also can be more accurate；Frame
The bottom of frame 1 is provided with footing 8, and footing is welded as star for three block length shape iron plates, and footing vertical welding, in framework bottom, passes through
Such structure had both eliminated manpower, improve the degree of accuracy of detection graphite resistance rate again.
