The invention discloses a signal leading-out device for an electrical performance test and a power-up test of a power supply filter. A mounting seat can be connected with a shell of the power supply filter in a positioning manner through a self-positioning structure, a plurality of pins or jack columns arranged in parallel are fixedly mounted on a plug-in mounting plate, and a plurality of plug-inthrough holes are formed in the mounting seat; the plug-in mounting plate is connected with the mounting seat, the first ends of the multiple pins or jack columns penetrate through the multiple plug-in through holes respectively and can be connected with the multiple lead-out jack columns or lead-out pins in a one-to-one correspondence mode, and the first ends of the multiple wires are electrically connected with the second ends of the multiple pins or jack columns respectively. According to the invention, the plurality of lead-out jack columns or lead-out pins of the power supply filter canbe conductively connected with the plurality of wires through the plurality of corresponding pins or jack columns, and the independent connection between the power supply filter and external equipmentis not influenced by the small distance between the plurality of lead-out jack columns or lead-out pins of the power supply filter; and the accuracy of a test result and the safety of a power-up testare ensured.
Description
technical field [0001] The invention relates to an auxiliary device of a power supply filter, in particular to a signal extraction device used for the electrical performance test and power-on test of the power supply filter. Background technique [0002] At present, power filters have been widely used in the field of electronic information by virtue of their own advantages. In order to confirm whether the power filter meets the requirements of use, it must be tested for its electrical performance; at the same time, in order to ensure that the power filter can work normally and stably between the power supply and electronic equipment for a long time, the power filter is usually tested before leaving the factory. Power up test. Whether it is an electrical performance test or a power-on test, it is necessary to connect the terminal of the power filter to the equipment according to the corresponding requirements for electrical performance test or power-on work, that is, to lead...
