[utility model content]
The purpose of this utility model be to provide a kind of easy to use, precision is high, point apparatus is sought in the contraposition that can seek test point time saving and energy savingly.
For achieving the above object, the utility model has disclosed a kind of contraposition that is applied to seek a little at the reverse side of tabula rasa in the computer main board test process and has sought point apparatus, on this mainboard except that having printed wire, circuit component also is installed, have the circuit identical on this tabula rasa, but circuit component is not installed on it with the printed wire of mainboard.This contraposition is sought point apparatus and is comprised a center connector, and isometric and rubber-like two jig arm that extend out from the center connector, and the terminal corresponding position of two jig arm is respectively equipped with a probe.In case the front tested point on mainboard is sheltered from by circuit component, then can use the utility model contraposition to seek point apparatus, positive reference point with a probe alignment tabula rasa front, remove to clamp tabula rasa with two jig arm from positive and negative two sides again, at this moment, can be exactly obtain the point identical as the reverse side reference point with positive reference point at the reverse side of tabula rasa, and simultaneously by multimeter measure numerical value confirm, and then find out with this reverse side reference point corresponding as the reverse side tested point at the reverse side of mainboard.The reverse side tested point measured to obtain and the front tested point is measured identical parameter.
Compared with prior art, point apparatus is sought in the utility model contraposition only to be needed singlehanded just can operate, and can vacate the another hand and keep a record or do other work.In addition,, do not need with the naked eye to compare repeatedly, saved the accuracy of running time and searching loci greatly, improved the speed and the precision of seeking a little because isometric both arms can strictly be aimed at.
[description of drawings]
Fig. 1 is a structure drawing of device of the present utility model.
[embodiment]
See also shown in Figure 1ly, the utility model contraposition is sought point apparatus 1 and is comprised a center connector 11, and rubber-like two jig arm 12,13 that extend out from this center connector 11.The strict equity of two jig arm 12 and 13 length.The terminal corresponding position of two jig arm 12,13 is respectively equipped with a chassis 14, and an end to be connected the needle point of probe 15, two probes 15 that the other end on the jig arm inwardly passes in the middle of 14 from the chassis relative.When two jig arm 12,13 were inwardly closed, the needle point of two probes 15 can strictly be aimed at.Each jig arm 12,13 all is provided with anchor clamps 16 in the place near center connector 11, and in order to two test pens 21,22 of clamping one multimeter 20, test pen 21,22 is respectively by jig arm 12,13 and two probes, 15 electrical communication.
Before seeking a little, at first as described in the background art, need possess the test drawing that a mainboard to be measured (not shown), indicates some positive reference point, and one with the identical tabula rasa that circuit component is not installed (not shown) of circuit on the mainboard to be measured.When seeking, seek a certain positive reference point according to the front that is indicated in tabula rasa on the test drawing earlier.After finding positive reference point, the trend according to the printed wire on tabula rasa and the mainboard can find the point identical with this front reference point as the front tested point easily in the front of mainboard again.In case the front tested point on mainboard is sheltered from by circuit component, then needs to use the utility model contraposition to seek point apparatus 1.The utility model contraposition is sought the positive reference point in a probe 15 aligning tabula rasa fronts of point apparatus 1, remove to clamp tabula rasa with two jig arm 12,13 from positive and negative two sides again, at this moment, can be exactly obtain the point identical as the reverse side reference point, and confirm by multimeter 20 with positive reference point at the reverse side of tabula rasa.Then, can find out with this reverse side reference point corresponding at the reverse side of mainboard as the reverse side tested point.Because this reverse side tested point and front tested point are same point on circuit board, so, 2 electrical quantitys of locating are identical, so under the situation that the front tested point is blocked, can estimate mainboard by the electrical quantity of measuring the reverse side tested point fully and whether meet production requirement.
