Our method to FPC board test of being familiar with at present, be all plant pin on product, test product, small-sized distance is crossed and is planted pin by micropin, thus to each electrode resistance of monolithic on FPC plate, electric current, voltage and open circuit, short circuit, etc. the test of original paper function.When some needs to adopt 4W test, plant pin position not, or easily prick partially, cause pricking and forbidden.Simultaneously, because present FPC plate is along with the development of science and technology, product requirement is more and more less, more next exquisite, small and exquisite practicality, the testing requirement that Connector connector is more and more higher, need in the little place acupuncture treatment of the crowding measure such as FPC or PCB, so connector is more and more less now, need the more and more less of acupuncture treatment, plant the more and more of pin, therefore present pin is more and more less, more and more higher to the requirement of pin, again because present pin can not meet the demands, frequent appearance is pricked inaccurate, prick less than situation, result through rate extremely low, stability extreme difference, thus affect the development of measurement jig greatly.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of coaxial probe, to make to plant pin on FPC plate, crosspointer can be planted in very little distance situation, to reach the demand of test, meet the testing requirement of each large product, more Small Distance adopts four line tests to provide sufficient space condition, to reach the demand of planting pin spacing.
The utility model in order to the technical scheme solving its technical matters and adopt is: a kind of coaxial probe, comprise little probe and large probe, this little probe comprises little probe contactor and is arranged at this little probe contactor one end and can the little probe test syringe needle that moves up and down of this little probe contactor relative; This large probe comprises large probe contactor and is arranged at this large probe contactor one end and can the large probe test syringe needle that moves up and down of this large probe contactor relative; This little probe coaxial sleeve is located in this large probe, and insulate between this little probe contactor and this large probe contactor and be fixedly connected with, this little probe test syringe needle to be movably placed in this large probe test syringe needle and not by stretching out during external force outside this large probe test syringe needle.
As further improvement of the utility model, the entire length of described little probe is greater than the entire length of described large probe.
The beneficial effects of the utility model are: this coaxial probe, can meeting product needed to be measured, to plant pin position very little, tying point spacing is very little, need again to plant the requirement that crosspointer adopts four-wire method test, this coaxial probe, by the leading contact product of the little probe of probe interior, is adjusted back by elasticity, again by the large probes touch product of outside, in this large and small probe, insulation, so two probes can not contact, there will not be short circuit problem.Because probe ride out is higher than the little probe height in inside, so crosspointer can well contact product, so two probes are fixed together by insulating material, the spacing of two needle points is very little, can plant lower outside probe and just can plant crosspointer and adopt four-wire method test, and to plant pin position is for the pin heart with tying point center for the place that product to be measured is little, for the distance that product orientation is put, do not affect the acupuncture treatment position of pin, thus ensure that the accuracy of test result, and greatly improve testing efficiency.
