Description
Technical field
The utility model relates to a kind of radio frequency testing device, and specifically a kind of radio frequency testing case, belongs to radio frequency testing device field.
Background technology
Radio frequency is that a kind of high-frequency ac changes electromagnetic abbreviation, be widely used in the field such as radio communication, electronic recognition, owing to being filled with electromagnetic wave in space environment, when radio frequency terminal electronic product is tested, in order to itself and external electromagnetic interference wave signal are isolated, avoid having an impact to test result, successfully test, generally product is put into the radio frequency testing case with electro-magnetic screen function and test.Name is called that " radio frequency testing case " application number be that the Chinese utility model patent of " 201320425299.6 " discloses a kind of radio frequency testing case, comprises shielding case body, and the shield door that is connected through the hinge of shielding case body; Described shield door surrounding arranges the shielding edge of a knife bent inwards, and it is U-shaped shielding cutter groove that the surrounding of described shielding case body doorframe arranges the xsect corresponding with the shielding edge of a knife, and shielding case body and shield door are by shielding cutter groove and the sealing of shielding edge of a knife press fit; The inner side of described shielding cutter groove inner chamber and the shielding edge of a knife all arranges the flexible shielding silk screen bar of band; Described radio frequency testing case is the complex of metallic matrix and metal surface.Although this device effectively can shield multiple external interference wave, use inconvenience, also dangerous, serviceable life is lower.
Utility model content
In order to solve the problem, the utility model devises a kind of radio frequency testing case, and sealing effectiveness is better, and safety easy to use, extends serviceable life, and result of use is good.
The technical solution of the utility model is:
Radio frequency testing case, comprises shielding case body and shield door, and described shielding case body and the bottom of shield door are connected through the hinge, and described shielding case body and the top of shield door are interlocked position; The shielding edge of a knife that described shield door is arranged, the described shielding edge of a knife is for being inverted T-type structure, described shielding case body is arranged the shielding cutter groove that the xsect corresponding with the described shielding edge of a knife is inverted u-shaped, described shielding case body and shield door are by shielding cutter groove and the sealing of shielding edge of a knife press fit, the described shielding edge of a knife is rubber structure, the large toughness of elasticity is high, and sealing property is better.
Further, the surface of the described shielding edge of a knife is coated with shielding film plating layer; Described shielding case body is the metal construction such as pure iron, steel with magnetic conductivity and electric conductivity, and top layer is also coated with the magnetic conductivity such as copper, nickel and the electric conductivity coat of metal stronger than matrix.
The utility model has the advantage of: sealing effectiveness is better, and safety easy to use, extends serviceable life, and result of use is good.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
