Description
Technical field
The utility model relates to a kind of proving installation and probe apparatus thereof disturbing for testing electromagnetic radiation.
Background technology
At present, all electronic products all must force to do 3C authentication.Electromagnetic interference in 3C authentication item (RE) is the authentication item that more difficult test is passed through.Large enterprise is generally that solve in self-built EMC laboratory, but early investment is very large.SMEs can only arrive the test of professional EMC laboratory and rectification, and slip-stick artist usually needed for a large amount of time of rectification cost, expense in the rectification of professional EMC (ElectromagneticCompatibility) laboratory is charged according to time, so want expensive expense.
No matter be the self-built EMC of large enterprise laboratory, SMEs, to the test of professional EMC laboratory and rectification, all needs expensive expense.
Utility model content
The technical matters that the utility model need solve is to overcome above-mentioned deficiency, provide a kind of cost low, realize simple, easy to operate electromagnetism test probe device.
For solving above-mentioned technical matters, the utility model has designed a kind of electromagnetism test probe device, it comprises by the annular probe of plain conductor coiling, coaxial cable and the bnc connector being connected with the first end of described coaxial cable, described annular probe comprises disjunct first end and the second end, the first end of described annular probe and the inner core of described coaxial cable the second end are electrical connected, and the second end of described annular probe and the screen layer of described coaxial cable the second end are electrical connected.
As the utility model, further improve, described annular probe is coiled into 2 circles.
As the utility model, further improve, described in turn to annular probe plain conductor be copper cash.
As the utility model, further improve, described copper cash is also wrapped by one deck coat of paint.
The utility model also provides a kind of electromagnetism proving installation, and it comprises above-mentioned electromagnetism test probe device and spectrum analyzer, and the bnc connector of described electromagnetism test probe device is connected with spectrum analyzer.
The utility model electromagnetism test probe apparatus structure is simple, and cost is low, almost without dropping into, just can realize the rectification of radiation interference project.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the utility model embodiment electromagnetism test probe device.
Embodiment
In order to make relevant technical staff in the field understand better the technical solution of the utility model, below in conjunction with the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.
The utility model provides a kind of electromagnetism test probe device, simple in structure, almost can zero cost self-control.As shown in Figure 1, this electromagnetism test probe device comprises annular probe 1, bnc connector 2 and is connected annular and pops one's head in 1 and one section of coaxial cable 3 of bnc connector 2.
Annular probe 1 is formed by one section of plain conductor coiling, and in the present embodiment, annular probe 1 becomes 2 circles by one section of copper wire winding, and this copper cash is also wrapped by one deck coat of paint as outer protection insulation course.Certainly in other embodiments, the number of turns of annular probe 1 does not limit to a number or amount, and can be 3 circles or 4 circles etc.The two ends of this section of copper cash are free end, are not connected, and the two ends of copper cash are first end and second end of annular probe 1.
Bnc connector 2 is a kind of connector for concentric cable, and full name is Bayonet NutConnector.Bnc connector 2 is connected with spectrum analyzer.
Coaxial line structure, ecto-entad comprises sheath, screen layer (outer conductor), insulating medium and inner core (inner wire) successively.The first end of the utility model coaxial cable 3 is connected with bnc connector 2; The inner core 31 of the second end of coaxial cable 3 is electrical connected with the first end of annular probe 1, and the screen layer 32 of the second end of coaxial cable 3 is electrical connected with the second end of annular probe 1, to induction current, provides full current return path.
The bnc connector 2 of the utility model electromagnetism test probe device is connected with spectrum analyzer, forms an electromagnetic probe device.The optional position of using annular probe 1 scanning electron product, spectrum analyzer is analyzed data, and the result of testing by Yu certification authority contrasts, find and test the only radiation source of frequency, the row that goes on is is again rectified and improved, and after repeatedly testing and rectifying and improving, rectification effect is assessed in the relative variation of recycling radiation source.
The utility model electromagnetism test probe apparatus structure is simple, and cost is low, almost without dropping into, just can realize the rectification of radiation interference project.
Below only expressed a kind of embodiment of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
