Background
Many electronic products need to work under the condition of high voltage, so the PCB board needs to be subjected to voltage withstanding test, especially the coil board, the working voltage of the PCB board is usually high, and when the working voltage reaches the high voltage of more than 2KV, the requirement of the voltage withstanding fixture is increased. When the existing voltage-resistant jig is used for measuring at each time, all test plates on the jig can only be judged, and which test plate fails cannot be independently determined, and the supporting frame of the air cylinder is supported by a single side, after the air cylinder is used for a period of time, due to the fact that stress is concentrated on one side, the upper cover plate is uneven, the test plates and the cover plate cannot be tightly attached, and when the working voltage is increased to be more than 2KV and the distance between the test points is small (about 1mm), air arc breakdown occurs, so that misjudgment failure is caused. Therefore, a high-voltage resistant jig for the coil plate is provided.
SUMMERY OF THE UTILITY MODEL
The utility model discloses solve the technical problem that above-mentioned prior art exists, provide a high pressure resistant tool of coil plate.
In order to realize the above-mentioned purpose, the utility model discloses a following technical scheme, a high pressure resistant tool of coil plate, the on-line screen storage device comprises a base, the base is rectangular plate-shaped structure, and intermediate position upper end fixed mounting of base has the support frame, and the vertical downward fixed mounting of upper end intermediate position of support frame has the cylinder, and parallel fixed mounting has insulating cover plate on the lower extreme output shaft of cylinder, and insulating cover plate's up end is provided with the presser foot, and the upper end fixed mounting of base has sample installation tool, and sample installation tool upper end demountable installation has the multiunit to survey the board, the right side of base is provided with multichannel withstand voltage tester.
Preferably, the insulating cover plate is a rectangular plate made of insulating material.
Preferably, the support frame is a portal support.
Preferably, the pressure feet have five groups in total, and the five groups of pressure feet are respectively arranged at the four corners and the center of the insulating cover plate.
