Abstract
The utility model discloses a telescopic antenna grounding device, which belongs to electromagnetic compatibility tests and comprises a metal plate with a connector mounted thereon, an annular belt and a support. The support is connected with the metal plate by the aid of the connector and supports the metal plate. One end of the metal plate is overlapped with a ground screen of the telescopic antenna, fine electrical contact between the metal plate and the ground screen is acquired by the aid of the contraction elasticity of the annular belt, and the other end of the metal plate is overlapped with a metal grounding plate of a testing workbench. The grounding device in mating use with the telescopic antenna during the electromagnetic compatibility tests is not only convenient for mounting, but also capable of meeting requirements for test standards, and accordingly efficiency and accuracy of the tests are improved.
Description
Technical field
The utility model relates to the EMC test field, a kind of specifically telescopic antenna earthing device.
Background technology
Telescopic antenna is the very high a kind of antenna of frequency of utilization in the EMC test, and as shown in Figure 1, it mainly is made up of pull bar 1, impedance matching network 2 and square earth mat 3.According to EMC test standard (as GJB 152A-97 " military equipment and subsystem electromagnetic emission and susceptibility are measured "), require earth mat 3 length of sides of telescopic antenna to be at least 600mm, when carrying out EMC test, need the centre distance test job edge of table of metal earth mat (being that the length of side is the rectangle of 600mm at present) that the distance of 1m must be arranged, therefore the direct overlap joint of the metal ground plate of earth mat and test table needs one of use telescopic antenna earth mat 3 to be snapped on the ground plate with wide real core metal band with earth mat 3.
At present, the EMC test in the shielded enclosure is used the test table that has metal ground plate usually, replaces ground plate by metal ground plate, therefore can use real core metal band that the earth mat of telescopic antenna is snapped on the metal ground plate of test table.
But the mode on this metal ground plate that the earth mat of telescopic antenna is snapped into test table by the solid metal band has had requirement to the length of real core metal band.The real core metal band weight that can satisfy the width of standard-required and length simultaneously is not light yet, can't directly be overlapped on the metal ground plate of the earth mat of telescopic antenna and test table.
Summary of the invention
In order to address the above problem, the utility model is according to the EMC test standard, and the telescopic antenna earthing device between a kind of metal ground plate that is installed in telescopic antenna and test table is provided, and comprises metallic plate, connector, endless belt and support.Wherein connector is fixedly mounted on horizontally disposed metallic plate bottom surface, and the top of support is mated with connector and linked to each other; Be with the rubber-like endless belt on the metallic plate.
After telescopic antenna and test configurations border arrange, the utility model telescopic antenna earthing device is placed on the floor between the metal ground plate of the earth mat of telescopic antenna and test table.Be with an end of endless belt and the earth mat overlap joint of telescopic antenna on the metallic plate, earth mat places between metallic plate and the endless belt; The fixing overlap joint of the other end of metallic plate and the metal ground plate of test table makes metallic plate closely contact with the outer maintenance of the metal ground plate of test table, to obtain good electrical contact.
Advantage of the present utility model is:
1, the utility model telescopic antenna earthing device with the supporting use of telescopic antenna, both had been convenient to install when carrying out EMC test, satisfied the requirement of test standard again, had improved the efficient and the accuracy of test.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of telescopic antenna earthing device of the utility model is as Fig. 2, metallic plate 4, connector 5, endless belt 6 and the support 7 of comprising shown in Figure 3.Wherein, described metallic plate 4 has good electrical conductivity, and its material can adopt the higher materials of conductance such as copper, aluminium, silver.Metallic plate 4 is horizontally disposed with, and the width of metallic plate 4 is identical with earth mat 3 width of telescopic antenna, and the width of metallic plate 4 is at least 600mm, thereby reaches testing standard.The length of described metallic plate 4 is 700～800mm.Described connector 5 is screw or nut, and connector is fixedly mounted on metallic plate 4 bottom surfaces, and connector is used for realizing being connected of 7 on metallic plate 4 and support.
Described support 7 is a lazy board, and the height of support 7 is adjustable between 800mm and 1000mm.The top of support 7 is mated with connector 5 and is linked to each other, and support 7 links to each other with metallic plate 4 by connector 5 thus, reaches the purpose of support metal plate 4.The load-bearing of support 7 and size are determined according to the weight and the size of metallic plate 4.
Be socketed with rubber-like endless belt 6 on the metallic plate 4, make the earth mat 3 in metallic plate 4 and the telescopic antenna have excellent electric contact by endless belt 6.
After telescopic antenna and test configurations border 8 arrange, the utility model telescopic antenna earthing device is placed on the floor 9 between the metal ground plate 10 of earth mat 3 test tables of telescopic antenna.Be with an end of endless belt 6 and earth mat 3 overlap joints of telescopic antenna on the metallic plate 4, earth mat places between metallic plate 4 and the endless belt 6; The other end of metallic plate 4 and the metal ground plate of test table 10 fixing overlap joints make metallic plate 4 closely contact with the metal ground plate 10 outer maintenances of test table, to obtain good electrical contact.
