Background technology
Along with modern electronic technology is fast-developing, the Electro Magnetic Compatibility of electronic equipment seems more and more important, as the wave filter that suppresses electromagnetic interference (EMI), also in each class of electronic devices, obtain a wide range of applications, also the Performance Detection of power-supply filter is had higher requirement simultaneously.Traditional to the detection of wave filter break-make, insulation, the unit for electrical property parameters such as withstand voltage once only to a wave filter, efficiency is very low, for same specification wave filter in enormous quantities, exist and detect the shortcomings such as classification is many, speed is slow, efficiency is low, because the wave filter unit for electrical property parameters of same specification type is identical, thereby for this feature, need to propose corresponding multi-functional testing unit for electrical property parameters.
Summary of the invention
The object of the invention is to overcome the deficiency of existing detection means, same specification type filter in enormous quantities is proposed to a kind of multi-functional testing unit for electrical property parameters of power supply filters and method for designing thereof.
The technical solution adopted for the present invention to solve the technical problems is: design a kind of multi-functional testing unit for electrical property parameters of power supply filters and method for designing thereof, it is characterized in that: multi-functional testing unit for electrical property parameters of power supply filters comprises base, insulating support, connection bus, connector block, hold down gag, switch testing parts; Two insulating supports are fixed on base by length direction is parallel; Between two insulating supports by the length direction device that is fixed and clamped; Tested wave filter is fixed in hold down gag lower end, and tested wave filter is uniformly distributed by length; Fixedly connector block and positive and negative two connection buss respectively on two insulating supports; Weld with positive and negative the two poles of the earth of two connection buss respectively at positive and negative the two poles of the earth of connector block; By the switch testing parts installed on connection bus, the measuring current between bus is opened a way and the control of path.
Described base is that the copper plate by plating nickel on surface is made.
Described insulating support is to be made by epoxy resin board, is used for avoiding short circuit between all kinds wave filter etween the lines and each wave filter.
Described connection bus is to be made by copper belt, and positive bus-bar and negative busbar are arranged on insulating support respectively with the positive and negative electrode of connector block by being weldingly connected.
Described connector block consists of red/black wiring insulated terminal gripping with fast lock and test connecting line.
Described hold down gag is comprised of depression bar, fastening bolt and insulation flexible material, and it is good that effectively fixed filters makes its ground connection, and insulation flexible material effectively prevents that the distribution parameter of wave filter and depression bar is coupled and avoids filter table surface damage.
Advantage of the present invention is, when improve detecting the test speed of unit for electrical property parameters of specification power-supply filter of the same type in batches and the accuracy of test, to have saved a large amount of costs and human resources, for favourable hardware facility has been created in actual production.
