Abstract
The invention discloses an EMC (Electro Magnetic Compatibility) test bench which comprises a first bench top, a second bench top and a motor, wherein the second bench top is arranged horizontally; the first bench top is arranged at the upper part of the second bench top in parallel; the second bench top is connected with a drive shaft of the motor by a rotating shaft; the motor is arranged at the lower part of the second bench top; holes are formed in the centers of the first bench top and the second bench top respectively; a wiring channel is formed between the two holes; and the two ends of the wiring channel are connected with the two holes respectively. The test bench is provided with the wiring channel, so that a power line of a tested product is built-in, and potential safety hazards are avoided. A shielding layer is arranged in the wiring channel, so that conducted interference of the power line is avoided in a test process, and the test accuracy is improved.
Description
Technical field
The invention discloses a kind of EMC test board, belong to electromagnetic compatibility test apparatus field.
Background technology
Electromagnetic compatibility (EMC) is the Comprehensive Assessment at interference size (EMI) and antijamming capability (EMS) aspect electromagnetic field to electronic product, is one of most important index of product quality, and the measurement of electromagnetic compatibility is comprised of test site and testing tool.
Test site mainly comprises: open area test site, semi-anechoic chamber, screened room.Testing apparatus mainly comprises: 1, anechoic chamber, 2, receiver 3, receiving antenna 4, artificial mains network, 6, turntable, lifting table 7, turntable, lifting table controller; Wherein, turntable mainly comprises a rotary table top and a fixedly turntable being arranged on rotary table top, during test, only the product of energising normal operation need be placed on fixedly on turntable, by revolving-turret, drive fixedly turntable to rotate, make product rotation, receiving antenna receives the electromagnetic wave that this work product sends, and tests.
This turntable is in test process, and the power supply of test products all accesses by outside, and power lead is generally arbitrarily to take to be put in fixedly on desktop, and when turntable rotates, power lead is followed turntable and rotated together, so just causes following problem:
(1) power lead is externally exposed, when electric current is large, can sends and pass to interference, and the electromagnetic wave that receiving equipment is received is not exclusively the electromagnetic wave that test products sends, and test result is caused a deviation.
(2) power lead is followed universal stage rotation, and the oversize line that easily causes of line is chaotic, if be stuck, is easily that test products power supply disconnects or test products is dragged on the ground, has potential safety hazard.
Therefore, existing test table also exists problem demanding prompt solution.
Summary of the invention
Technical matters to be solved by this invention is: a kind of EMC test board is provided, has increased shielding trough, solved the exposed problem causing outside of the power lead existing in prior art.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of EMC test board, comprise the first table top, the second table top, motor, described the second table-surface level setting, the first table top is set in parallel in the second table top top, described the second table top is connected with the driving shaft of motor by turning axle, and described motor is arranged at the second table top bottom, the perforate respectively of described the first table top center and the second table top center, between two perforates, trough is set, the two ends of described trough are connected with two perforates respectively.
On described the first table top, stationary installation is set, for fixed power source output port.
Described the first table top is regular geometric shapes, and described the second table top is circular.
Described trough inside arranges screen layer.
Described screen layer is a kind of in wire netting, aluminium-foil paper, the coat of metal.
Compared with prior art, beneficial effect of the present invention is:
(1) this device arranges trough, makes the power lead of test products built-in, avoids potential safety hazard.
(2) in trough, screen layer is set, has avoided the Conduction Interference of power lead in test process, increased test accuracy.
(3) output port of power source stationary installation is set on fixed mesa, has facilitated the power supply access of test products.
(4) fixed mesa is set to difformity, can test targetedly the product of different structure, handled easily.
Accompanying drawing explanation
Fig. 1 is structural representation Fig. 1 of the present invention.
Fig. 2 is structural representation Fig. 2 of the present invention.
Wherein, being designated in figure: 1-the first table top; 2-the second table top; 3-trough; 4-fixed support; 5-output port of power source stationary installation; 6-power lead.
Embodiment
Below in conjunction with drawings and Examples, technical scheme of the present invention is elaborated:
As shown in Figure 1, a kind of EMC test board, comprise the first table top 1, the second table top 2, motor, described the second table top 2 is horizontally disposed with, and the first table top 1 is set in parallel in the top of the second table top 2, and described the second table top 2 is connected with the driving shaft of motor by turning axle, described motor is arranged at the bottom of the second table top 2, the perforate respectively of the center of the center of described the first table top 1 and the second table top 2, arranges trough 3 between two perforates, and the two ends of described trough 3 are connected with two perforates respectively; Described First basifacial is fixedly connected with fixed support 4, and for being connected with the second table top 2, fixed support 4 can be fixedly connected on the top of the second table top 2, or is movably connected on the top of the second table top 2.
On described the first table top, output port of power source stationary installation 5 is set, for fixed power source output port.
Described the first table top 1 is regular geometric shapes, comprises circle as shown in Figure 1, or as shown in Figure 2 square, or other geometric configuratioies can be according to product setting, and described the second table top 2 is circular.
Described trough 3 inside arrange screen layer.
Described screen layer is a kind of in wire netting, aluminium-foil paper, the coat of metal.
Installation and the course of work of this device are as follows:
In the screened room of EMC test, all have from the power supply of underground introducing screened room, and be specifically designed to the space that prevents the opertaing devices such as motor, this equipment is all placed in the bottom of rotary table top, trough by power lead 6 through this device, trough is fixedly installed in to the centre of the second table top (rotary table top), and the first table top (fixed mesa) is fixed on the second table top, and the central through hole of the first table top is aimed in trough one end, the output terminal of power lead is fixed on to the first mesa surfaces, while facilitating test products, switches on power.
This device trough top also can arrange lid, if trough diameter is greater than the quarter-wave of power lead conducted signal, has both caused radiation, needs to arrange shielding cover body, prevents test products to impact.
During test products, product is positioned on the first platform, directly by product power connection, with shorting stub, is advisable, turn on the power switch, production debugging, to normal operating conditions, can be opened to motor, start rotation platform work, test.
