Utility model content
The purpose of this utility model is: for the deficiency of traditional E MC pick-up unit, and a kind of new E MC pick-up unit is provided, this EMC pick-up unit can detect the electromagnetic size of undesired signal in vertical polarization direction and horizontal polarization direction respectively, ensures the accuracy of the electromagnetic compatibility result of test.
For achieving the above object, the utility model adopts following technical scheme: a kind of EMC pick-up unit, comprise antenna, signal processor, support bar, guide rail, saddle weight and test board, described guide rail is arranged at described test board, described support bar is connected with described slide, described signal processor is arranged at one end of described support bar, described saddle weight is arranged at the other end of described support bar, described antenna and described signal processor are electrically connected, and described antenna comprises horizontal signal receiving antenna and vertical signal receiving antenna.
Described horizontal signal receiving antenna is parallel with described support bar, and described vertical signal receiving antenna is vertical with described support bar.
The inside of described guide rail is provided with sawtooth slide rail.
The junction of described support bar and described guide rail is provided with motor, and described motor drives described support bar at described slide on rails.
The inside of described support bar is provided with trough, and the outer wall of described trough is attached with one deck screen layer, and the inside of described trough is provided with transmission line.
Described horizontal signal receiving antenna and described vertical signal receiving antenna are all set to triangle iron hoop structure.
The beneficial effects of the utility model are: the EMC pick-up unit that the utility model provides comprises antenna, signal processor, support bar, guide rail, saddle weight and test board, guide rail is arranged at test board, support bar is connected with slide, signal processor is arranged at one end of support bar, saddle weight is arranged at the other end of support bar, antenna and signal processor are electrically connected, antenna comprises horizontal signal receiving antenna and vertical signal receiving antenna, receive levels electromagnetic ripple signal and vertical electromagnetic wave signal respectively, achieve and signal can be sent in signal processor respectively, and the upright position of antenna is regulated by sawtooth slide rail, collect the Electromagnetic Interference signal of every one deck, finally by data processing, obtain test result accurately.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of antenna in Fig. 1.
Embodiment
Below in conjunction with embodiment and Figure of description, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
As shown in Figure 1 and 2, a kind of EMC pick-up unit, comprise antenna 1, signal processor 2, support bar 5, guide rail 7, saddle weight 9 and test board 10, guide rail 7 is arranged at test board 10, support bar 5 and guide rail 7 are slidably connected, signal processor 2 is arranged at one end of support bar 5, saddle weight 9 is arranged at the other end of support bar 5, ensure the steady of test board 10, prevent test board 10 from causing device to damage owing to toppling over, antenna 1 and signal processor 2 are electrically connected, and antenna 1 comprises horizontal signal receiving antenna 12 and vertical signal receiving antenna 13.
Preferably, horizontal signal receiving antenna 12 is parallel with support bar 5, and vertical signal receiving antenna 13 is vertical with support bar 5, can receive levels electromagnetic ripple signal and vertical electromagnetic wave signal respectively, and send in signal processor respectively and process, obtain test result accurately.
Preferably, the inside of guide rail 7 is provided with sawtooth slide rail 6.
Preferably, support bar 5 is provided with motor 8 with the junction of guide rail 7, and motor 8 drives support bar 5 to slide on guide rail 7.
Preferably, the inside of support bar 5 is provided with trough 4, the outer wall of trough 4 is attached with one deck screen layer 11, mask the electromagnetic wave that transmission line emits, the electromagnetic wave received is the electromagnetic wave that tested electronic product sends, guarantee test result is accurate, the inside of trough 4 is provided with transmission line 3, as the passage of transmission line 3, prevent transmission line 3 from following in support bar 5 lifting process, because transmission line 3 is oversize and cause transmission line 3 chaotic and be stuck, test products power supply is disconnected or test products is dragged on the ground.
Preferably, horizontal signal receiving antenna 12 and vertical signal receiving antenna 13 are all set to triangle iron hoop structure, can more large-area reception electromagnetic wave.
Because tested electronic product launches the electromagnetic wave that wavelength is 9KHZ ~ 1GHZ, electromagnetic wave can be propagated to all directions, in order to better acquired character, antenna is arranged to horizontal signal receiving antenna and vertical signal receiving antenna, and increase antenna and receive electromagnetic area, while increase antenna receives electromagnetic wave area, attractive in appearance in order to EMC pick-up unit, its antenna adopts triangle iron hoop structure, can more absorb the electromagnetic wave that different directions is propagated like this, and process in the electromagnetic wave absorbed feeding signal processor, finally transfer out accurate data.
