Description
Technical field
The utility model relates to detection tool application, particularly relates to a kind of novel probe for PCB open-short circuit and detects tool.
Background technology
At present, the open-short circuit of existing PCB detects tool and there is following shortcoming: one is that the diameter of minimum test probe in this detection tool is generally 0.15mm, and in the product of high-accuracy PCB, this test probe cannot detect normally because diameter is excessive; Two is that this detection tool does not generally possess floating Precise spraying, the probe of test is exposed and effectively cannot protect probe, also have impact on the result making it detect simultaneously.
2011.07.06 bulletin, notification number is in the Chinese utility model patent of CN20189269U, disclose a kind of probe detection structure of improvement, refer to detect tool needle plate in be provided with detection probe, the elastic parts resetted for probe of predetermined number and transfer to the wire of detection machine for detected value; Wherein, needle plate includes middle board, base plate and panel, they place combination by number axis pin mutually, it is accommodating for elastic parts that this middle board is provided with accommodation hole, this base plate is positioned at below middle board accepts elastic parts, be provided with corresponding with the accommodation hole of middle board also in less perforation, this wire one end is connected to elastic parts one end, and another end is connected to detection machine or joint; It is characterized in that: the elastic sheet that this panel is provided with upper plate, lower plate and is folded between upper and lower plate, the pin hole corresponding with elastic parts is respectively equipped with at upper and lower plate, this probe one end is set to taper, be inserted by the upper plate pin hole of panel, and puncture elastic sheet and be plugged on one end inner diameter location of corresponding elastic parts through lower plate pin hole.The utility model makes and has more simple and easy, convenient and economy, and can make that probe is highdensity is laid in detection tool, and the measured object with the tested measuring point of high density is implemented precisely, Detection results really, thus be more suitable for practicality.
But this detection architecture is the probe arranging more more number in needle plate, realizes with highdensity laying, therefore, it does not still solve the excessive shortcoming with effectively protecting probe of existing detection tool middle probe diameter.
Summary of the invention
For overcoming above-mentioned shortcoming; the purpose of this utility model is to provide a kind of novel probe to detect tool, has reached the diameter reducing probe, has made it normally detect in the product of high-accuracy PCB; and more effective protection probe, makes its testing result object more accurately.
In order to reach above object, the technical solution adopted in the utility model is: a kind of novel probe detects tool, comprise circuit-under-test plate, probe unit and connector, described probe unit comprises the draw-in groove being provided with in dials described in dials, probe and drum and blocking described probe, described probe diameter is set to 0.04mm, and the surface of described probe is provided with insulation course; Described drum is arranged on the below of described dials, the top of described drum is provided with electrode surface, floating member is provided with in described drum, it can drive drum carry out upper and lower compression and stretch out motion, described electrode surface is electrically connected with described connector by enameled wire, described probe is connected by contacting with electrode surface to be energized with described connector afterwards, opens short-circuit detecting to circuit-under-test plate.By the diameter of probe is set to 0.04mm, make it can detect normally in the product of high-accuracy PCB, probe can high density distribute, and makes it detect more efficiently; Insulation course is set on the surface of probe, can effectively avoids surveying because probe bends the mistake caused; In drum, be provided with floating member, floating member can compress drum as required or stretch out, the contact distance of control electrode face and probe; effectively can control the prominent amount of probe; and then more effective protection probe, also make its testing result more accurate, improve its accuracy of detection.
Further, described dials is set to the plate construction of storehouse, and the structure of Multilayer stack can reduce the resistance that probe runs up and down, probe is run more smooth and easy.
Further, between described dials adjacent two layers, be provided with copper pillar, be connected with copper pillar and closely sealed, make dials more firm, the controlled range of sheet material tolerance also can be made less, effectively control pin trace.
Further, the surface of described electrode surface is coated with a Gold plated Layer, conductance with intensifier electrode face, reacts sensitiveer after making its admittance.
