Description
Technical field
The present invention relates to the automotive electronics in EMC test technology and national military standard field, are a kind of test backmans
Dress.Can be according to the different length for changing tooling for harness length in testing standard, the note being accurately positioned in immunity to interference test
Enter, monitoring probe.Single test fixture is integrated, meets the requirement of each international standard and depot's standard.
Background technology
Radiation disturbance is primarily referred to as that energy is emitted to space by source in the form of an electromagnetic wave or energy is existed with electromagnetic wave
The phenomenon that spatial, the exceeded product of radiation disturbance may cause peripheral devices, equipment or system performance to reduce, interference information
The normal work of technical equipment or other electronic products, and human body is caused centainly to endanger.Sample surfaces, cable connectivity port,
Power cord and signal wire are all radiation disturbance sources, at the same also be subject to interference must survey position and test be most easily detected by
And the project of rectification is most difficult to, so the radiation disturbance of electronic product and the testing precision of immunity to interference require also more and more strictly.
Electromagnetic compatibility test harness and injection probe, the method for arranging of monitoring probe are defined in national military standard GJB-151B：
With the 2m line segments of every interconnection cable of sample termination（Unless the cable length in actual installation is shorter than 2m）Configuration should be parallel to
Front border wiring, all cables are all supported with non-conductive support object, and the 5cm above ground connection tablet, the dielectric of supporter are normal
Number should be low as possible；Monitoring probe is placed in away from sample port 5cm in the injection conducted susceptibility test of CS114 bunchs of cables, and injection is visited
Head is placed in away from detection probe 5cm.
In automotive electronics electromagnetic compatibility test International Organization for standardization ISO and International Radio Interference Committee CISPR with
And major depot（Masses, Ford etc.）Standard in have respectively for radiation-emitting and radiation, the harness length of conducted immunity
The requirement of 100cm, 150cm and 170cm；BCI Bulk current injections have to the position of injection probe and monitoring probe 5cm, 15cm,
The requirement of 45cm, 75cm, 90cm.
Summary, traditional test fixture can only meet single testing standard, can not realize to harness length and anti-
That pops one's head in degree of disturbing test is accurately positioned.
Invention content
The present invention is to provide a kind of with length is adjustable, meets to flexibility the work required in each standard probe positions
Dress.Test fixture with positioning function can split into several parts, convenient for storing and carrying, after simply assembling, fill
Divide and meet in various criterion for the length of insulation stent requirement.It is straight on clamp device and tooling by movably injecting
Injection pincers are precisely located in ruler, and the place for conveniently completing electromagnetic compatibility test is built, and are saving laboratory's manpower, are carrying
The research and development testing cost of consigner is also saved while high testing efficiency.
In order to solve the technical issues of above-mentioned, the technical solution adopted by the present invention is：It is a kind of for electromagnetic compatibility test
Insulation support plate（All unit modules are all that ε r≤1.4 are made by the material of low relative dielectric constant）, the long 2m of insulation support plate,
Wide 20cm is highly 5cm.Including：Insulate main supporting plate, length 50cm support plates, length 30cm support plates, length 20cm
Support plate, spill fixing fitting five are most of.Each support plate module facilitates combination different length respectively with scale.
The main supporting plate length that insulate is 1m, is made of two parts, the probe support of 50cm Slidable supports plate and 5 10cm
Plate.It is concave shape slot among insulation main supporting plate, to place the probe support plate of 50cm Slidable supports plate and 5 10cm.
Length 50cm Slidable supports plate and other 5 probe support plates can be with spiral-locks on main supporting plate and can be on main supporting plate
It slides, to meet in various criterion for the requirement of probe positions.Such as：5cm, 15cm, 45cm, 75cm, 90cm etc..
Insulation main supporting plate card with length 50cm support plates can be coupled together using spill fixing fitting, can met
Radiation emission test as defined in CISPR25 and some auto vendor's standards.Length 20cm support plates are also to join in the same way
It is connected on main supporting plate, the length of 170cm is primarily to meet the radiated immunity test harness requirement of some auto vendors.
Equally, the connection of all parts can be met to the requirement of national military standard together.
Advantage is compared with traditional insulation support plate：The present invention, each independent support plate module is equipped with scale, right
In test site build really realize it is convenient, fast.All support plate modules can be combined freely, be dismantled, to meet difference
Requirement of the testing standard for test harness needs injection pincers to be used and monitoring to clamp in simple positioned conductive immunity to interference test.
The test error for avoiding artificial measurement and generating, is accurately performed test request.
