Abstract
The utility model discloses a low resistance tester which comprises a resistance display and two symmetrical test probes. The resistance display is electrically connected with the two test probes through connecting leads. Spacing of the two test probes is equal to that of two electrodes of a resistor to be tested. The two test probes are connected together through a connecting button. The two test probes contact with an element point, and no damage of elements occurs. The high-precision tester can be used to test resistance precisely with no damage of elements and is simple in structure and convenient to operate.
Description
Technical field
The utility model belongs to the testing apparatus field, and is particularly a kind of for low-resistance testing tool.
Background technology
The FPC plate of using in mobile phone, make very accurate, there is a little any to damage, the capital affects the use of FPC plate or directly scraps, need to test its resistance during use, its resistance is all very little, the multimeter precision is low, can not be used for testing this low resistance element, and the high tester of measuring accuracy is all to adopt chuck type, and chuck contacts with the direct face of element, easily the FPC plate is damaged, if can have a kind of testing tool of direct some contact just can not only test out its resistance but also not lose element, just above problem can be resolved fully.
The technical problems to be solved in the utility model be to provide a kind of measuring accuracy high, to the undamaged tester of element.
Summary of the invention
Above-mentioned prior art measuring accuracy is low in order to solve, the easy problem such as lesion element in test, and the utility model adopts following technical scheme:
The utility model provides a kind of low resistance tester, comprise resistance display and two symmetrically arranged test contact, described resistance display is electrically connected by being connected wire with two test contact, spacing between described two test contact is identical with testing resistance two die openings, and described two test contact link together by connecting button.
As to improvement of the present utility model, be wound with outside described connection button and make more firmly mightiness belt of two test contact connections.
As to further improvement of the utility model, bottom described resistance display, two bracing frames are installed.
The beneficial effects of the utility model are: contact with element point by two test contact, can lesion element, and adopt simultaneously high-precision tester, can test out very accurately resistance lesion element not again, apparatus structure is simple, and is easy to operate.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
see also Fig. 1, a kind of low resistance tester, comprise resistance display 1 and two symmetrically arranged test contact 2, described resistance display 1 is electrically connected by being connected wire 3 with two test contact 2, during test, first the power switch 12 on resistance display 1 is pressed, switch on power, then set the concrete correlation parameters such as range by function button 14, after parameter sets, the tester holds with hand two electrodes that test contact 2 is aimed at FPC plate to be measured, because contact and electrode are to contact, can not be damaged to electrode, and traditional testing tool is all to use chuck, it is the face contact, be easy to be damaged to components and parts, the spacing that described two test contact are 2 is identical with testing resistance two die openings, so not only guaranteed the accuracy of test but also improved efficient, the dynamics that hand is exerted oneself is smaller, the FPC plate in order to avoid damage, the result that tests out will be presented on the display screen 13 of resistance display 1, directly read to record and get final product, described two test contact 2 link together by connecting button 4, guarantee like this integral body that connects into that two test contact 2 can be very fastening, guarantee accurately and smoothly carrying out of test, simultaneously if test other elements and interelectrode spacing difference, button 4 can directly be rotatably connected.
In the utility model, be wound with outside described connection button 4 and make more firmly mightiness belt 5 of two test contact, 2 connections, can guarantee that like this two test contact 2 degree of being connected firmly are better, guarantee the accurate of test, life cycle can be longer simultaneously.
In the utility model, in described resistance display 1 bottom, two bracing frames 11 are installed, when test, can be placed directly in testing tool on desk, also can erect instrument come by bracing frame 11 more convenient like this testing cassete reading out data.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
