This utility model belongs to measuring instruments technical field, especially relates to the pen meter of universal meter of a kind of accurate measurement.
Background technology
At present, known pen meter of universal meter is made up of lead-in wire, handle and metal nib, and metal nib often uses diameter
Metallic object more than more than 2mm processes.But in actual applications, particularly in the test process of electronic circuit board, by
The thickest in metal nib, it may appear that problems with: 1, too near because of components and parts pin distances, it is very easy to that short circuit phenomenon occurs；2、
Cross that thick metal is written and between tested position frictional force not enough, test pencil easily slides, and causes loose contact or short circuit；3, for
The finest electronic circuit board, owing to locus is narrow and small, test pencil cannot stretch into and can not measure, it is impossible to the least to diameter
In the micropore narrow slit of 2mm, conductor measures.
Summary of the invention
For solving the problems referred to above, the purpose of this utility model be to provide a kind of simple in construction, easy to use, safe efficiently
The pen meter of universal meter of accurate measurement.
For achieving the above object, this utility model adopts the following technical scheme that
The pen meter of universal meter of a kind of accurate measurement, it includes the copper probe of a diameter of 0.5～1.2mm, copper probe
Head end is prong shape, and copper probe end connects copper connecting portion, and copper connecting portion passes through hollow aluminium hydraulic pressed connecting pipe and a circuit tester
Former test pencil nib connect, be connected between copper connecting portion end and the former test pencil nib outer wall of circuit tester and have 1,2 or many
Root copper cash, and copper cash passes by hollow aluminium hydraulic pressed connecting pipe, the former test pencil of circuit tester is written and copper connecting portion is for being coaxially set.
The pen meter of universal meter of described accurate measurement, its copper probe outer surface is provided with Gold plated Layer.
The pen meter of universal meter of described accurate measurement, its copper wire diameter is 0.3～0.5mm.
The pen meter of universal meter of described accurate measurement, it also includes being set in, and the former test pencil of circuit tester is written crimps with hollow
Heat-shrink tube on pipe.
Owing to using technical scheme as above, this utility model has a following superiority:
The pen meter of universal meter of this accurate measurement, its simple in construction, reasonable in design compact, cost of manufacture is low, easy and simple to handle, logical
Cross the former test pencil with circuit tester to be fastenedly connected, it is possible to diameter is less than in the 2mm micropore more than 0.6mm and narrow slit leads easily
Body detects, it is simple to the measurement at the electric positions of fine structure such as electronic circuit board, plug socket, narrow space, has good
Application value.

Detailed description of the invention
With embodiment, the technical solution of the utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, the pen meter of universal meter of this accurate measurement, it includes the gold-plated copper probe of a diameter of 0.5～1.2mm
3, the head end of copper probe is prong shape, and copper probe end connects copper connecting portion 4, and copper connecting portion passes through a hollow pressure
Adapter 5 is connected with the former test pencil nib 6 of circuit tester, and hollow aluminium hydraulic pressed connecting pipe internal diameter is more slightly larger than pen meter of universal meter, and hollow aluminium hydraulic pressed connecting pipe is copper
Or aluminum conductive material, be connected between former test pencil nib 6 outer walls of copper connecting portion 4 end and circuit tester have 1,2 along general-purpose
Symmetrical or many of the former test pencil nib outer wall of table is along the former test pencil nib equally distributed copper of outer wall circumferencial direction of circuit tester
Line 2, copper cash is passed by hollow aluminium hydraulic pressed connecting pipe 5, makes the former test pencil of circuit tester written and copper connecting portion is for being coaxially set.
Above-mentioned copper probe outer surface is provided with Gold plated Layer, wear-resisting and reduction conductive resistance.
Above-mentioned copper connecting portion 4 end and circuit tester former test pencil nib 6 outer walls between copper cash 2 a diameter of 0.3～
0.5mm。
The pen meter of universal meter of above-mentioned accurate measurement, it also includes being set in, and the former test pencil of circuit tester is written crimps with hollow
Heat-shrink tube on pipe.
The pen meter of universal meter of accurate measurement of the present utility model, when it makes, the copper connection that copper probe 3 end connects
Portion 4 welds together with former test pencil nib 6 copper cash 2 of circuit tester, in copper connecting portion end, the former test pencil nib of circuit tester
Outer wall is respectively provided with solder joint 1b, solder joint 1a；Copper connecting portion, circuit tester former test pencil nib on sheathed hollow aluminium hydraulic pressed connecting pipe 5, adjust
Crimp with Press Plier after whole good position；Shrinkable sleeve is complete after pyrocondensation on the written and hollow aluminium hydraulic pressed connecting pipe of former test pencil of circuit tester
Become to make.
The foregoing is only preferred embodiment of the present utility model, rather than to restriction of the present utility model, without departing from this
In the case of the spirit and scope of utility model, all impartial changes made according to this utility model claim and modification,
Within all should belonging to scope of patent protection of the present utility model.
