Summary of the invention
The purpose of this utility model is to propose a kind of circuit function test fixture that can improve wiring board testing efficiency and precision.
For achieving the above object, following technical scheme is provided:
Printed-wiring board (PWB) assembly circuit function test fixture, comprises test probe, and one end of test probe connects Error Detector connectivity port by test circuit, and Error Detector connectivity port is arranged on the surface of casing; Test circuit is arranged in casing, and the other end of test probe is arranged on outside casing top; The top of casing is installed with test pallet, test pallet is provided with the hole of matching with test probe, and test probe is through the hole on test pallet.Test probe and test circuit are by the actual BNC connecting line tested of circuit-line connecting analog, operating personnel are made not need manually to connect BNC connecting line, only need wiring board to be measured to be placed on test pallet can treat and survey wiring board and test, test result is undertaken analyzing and showing by external Error Detector.Test result is accurate, work efficiency is high.
Further, also comprise support, described support is fixedly mounted on the top of described casing; Saddle is fixedly mounted on support; The bottom of saddle is fixedly connected with sleeve, the top outwardly convex of saddle; Projection on one end of first web member and saddle is hinged, one end of middle part and the second web member is hinged, and the other end is fixedly connected with one end of handle; The other end of the second web member and one end of the axis of guide hinged; The other end of the axis of guide is fixedly connected with column dish, and the axis of guide is inserted in the sleeve bottom saddle.Moving down by pressing down handle strip action-oriented post, making column dish be pressed in the top of wiring board to be measured, wiring board to be measured can be made like this to contact closely with test probe, and test result is more accurate.
Further, at least two guide plates and guide pillar is also comprised; Guide plate is fixedly mounted on saddle, guide plate is provided with the hole of matching with guide pillar, and guide pillar is inserted in the hole on guide plate; Column dish is arranged the hole of matching with guide pillar, guide pillar is inserted in the hole on column dish; The bottom of guide pillar is fixedly connected with the top of casing.Remain vertical movement when column dish is moved up and down, when further making column dish compress circuit board under test, do not make wiring board offset, and then test result is more accurate.
Further, also comprise column, column is fixedly installed on the bottom of column dish.Due to wiring board to be measured arranging a lot of electronic devices and components, rough, contacted with wiring board to be measured by multiple column, the electronic devices and components on wiring board to be measured can not be damaged, the close contact making wiring board to be measured and test probe must be reached.
Further, also comprise fixed head, saddle is fixedly connected with support by fixed head.During owing to pressing down handle, saddle is stressed, and fixed head makes the junction of saddle and support more firm, increases the stability of apparatus structure.
Preferably, described guide pillar and guide plate are for being fixedly connected with.
