The outer case for the four-probe test instrument has the advantages that the manufacture is simple, the cost is low, the practicability is high, and the dark test environment can be provided for replacing a dark room.
Description
Technical field
The utility model relates to photovoltaic production technology apparatus field, is specifically related to a kind of outer container of four point probe tester.
Background technology
In the photovoltaic industry production, generally judge by the square resistance that detects silicon chip whether diffusing procedure is qualified, the instrument of test square resistance is the four point probe tester.And the four point probe tester need just can carry out test job in the environment of dark, carries out the mensuration to the silicon chip square resistance after at present generally being placed in the darkroom again.The construction in darkroom had both increased building cost, also formed management " blind area " simultaneously easily.
The utility model content
Technical problem to be solved in the utility model is at above the deficiencies in the prior art, provide a kind of make simple, cost is low, practical, can replace the darkroom that the four point probe tester outer container of dark test environment is provided.
For addressing the above problem, the utility model provides a kind of four point probe tester outer container, comprise permeability magnetic material sleeve, permeability magnetic material cover plate and magnetic material fixture, wherein fixture is made by magnetic material, it has the magnetic effect to sleeve and the cover plate of being made by permeability magnetic material, so can will connect between sleeve and the cover plate by fixture.One circular hole is arranged on the cover plate, and the diameter d of circular hole equals the urceolus diameter of four point probe probe of tester.
Described sleeve is cylindric, and internal diameter is 350mm～440mm, highly is 100～150mm.
Described cover plate by large circle, small circle ring, and the center drum that connects large circle and small circle ring form, the external diameter of cover plate equals the internal diameter of sleeve, the internal diameter of cover plate is that the internal diameter of small circle ring also is the diameter d of circular hole on the above-mentioned cover plate, the external diameter of center drum is 20mm～100mm, highly is 40mm～80mm.
Described four point probe tester outer container also comprises set screw, and set screw is passed center drum and carried out fastening to the four point probe probe of tester.
Described fixture is at least two, is preferably two.
Described set screw is at least two pieces, is preferably two pieces.
After adopting above structure, the utility model compared with prior art, have the following advantages: four point probe tester outer container comprises permeability magnetic material sleeve, permeability magnetic material cover plate and magnetic material fixture, fixture utilizes its magnetic effect tightly to link to each other with cover plate with the sleeve of permeability magnetic material and both positions is fixed, the outer container of four point probe tester just has been made into like this, makes very simple and convenient.Sleeve, cover plate are permeability magnetic material, and fixture is common magnetic material, so for building the darkroom, the cost of this four point probe tester outer container is quite low.After the outer container assembling, the chest sealing is good, and whole outer container inside is light tight, is dark surrounds, just can replace the darkroom to carry out test job, and is very practical.In addition,,, operate very simply, be applicable to test the different-thickness silicon chip so can regulate the height of cover plate at any time according to the demand of inner silicon chip and four point probe probe of tester because sleeve and cover plate attract by the magnetic material fixture and fix.
