The utility model discloses a half similar spherical structure, the position of carrying on the object plane locating hole and positioning groove according to measurement system measuring position and the relative position that is surveyed mould needs test position many times the tight calculation of assay draw, multiunit locating hole and positioning groove can adapt to not unidimensional measured object in addition. The utility model discloses can measure large -scale measured object (the test size can be greater than 110mm), can pinpoint when testing a plurality of test positions of same measured object.
Description
Technical field
The utility model relate to a kind of in Antenna testing system the fixture for clip-model.
Background technology
Along with the high speed development of communications industry, antenna measurement becomes more and more important, and at present, existing a lot of company manufacturing antenna is using Antenna testing system, and measure the item is also towards standardization more, diversified future development.
Antenna testing system is used to test, must test position be put to the fixed position that system is specified (being generally system centre), just can obtain accurate, stable test result, but the fixture of at present usually test mostly is little for mobile phone, loudspeaker, antenna equidimension and made by the object that measuring point is single.According to the requirement such as CTIA/3GPP, Chinese national standard, in the test event of antenna for mobile phone, the test of head mould, fingerprint or head fingerprint combination must be comprised.
Using a model often to need two of model and above position tests and model volume is comparatively large when testing, use conventional brace to be difficult to fixing test position, very easily occur error, affect test result.
Summary of the invention
The deficiency of the large mold with multiple test point can not be tested in order to overcome existing test fixture, the utility model provide a kind of in Antenna testing system the fixture for clip-model, can be good at fixing large mold, and fixture is reserved with sufficient pilot hole and detent, also can accurately locate after can ensureing change test position, the variable reduced in test process makes test result more reliable and more stable.
It is as described below that the utility model solves the technical scheme that its technical matters adopts:
A kind of in Antenna testing system for the fixture of clip-model, it is characterized in that, comprise chuck body, chuck body is provided with loading surface, loading surface is provided with many group pilot holes and detent, chuck body is provided with hollow space, and this hollow space is used for the pole in plug-in mounting fixed antenna test macro, chuck body is fixed on pole.
According to technique scheme, wherein said chuck body is like hemisphere.
According to technique scheme, the hollow space xsect in wherein said chuck body becomes isosceles trapezoid, up-small and down-big, is convenient to closely be fixed on pole.
The utility model adopts similar hemispherical dome structure, and loading surface is smooth but frictional force is comparatively large, and material hardness used is high, lightweight, can bear the weight of large mold and not produce obvious deformation.On the utility model loading surface, the position of pilot hole and detent needs to test the relative position at position according to measuring system measuring position and tested mould and repeatedly analyzes and tightly calculate, and organize pilot hole and detent more, the measured object of different size can be adapted to.
According to technique scheme, the beneficial effects of the utility model are as described below:
1, the utility model can measure large-scale measured object (test size can be greater than 110mm);
2, can accurately locate when the utility model tests multiple test position of same measured object.
below in conjunction with accompanying drawing and embodiment, the utility model is described further.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the utility model is described further.

As Figure 1-Figure 2, a kind of in Antenna testing system for the fixture of clip-model, comprise like hemispheroidal chuck body 100, chuck body is provided with loading surface 101, loading surface 101 is provided with many group pilot holes 102 and detent 103, chuck body is provided with hollow space 104, this hollow space 104 is for the pole in plug-in mounting fixed antenna test macro, chuck body 100 is fixed on pole, hollow space 104 xsect in chuck body 100 becomes isosceles trapezoid, up-small and down-big, be convenient to closely be fixed on pole.
Application example one
As shown in Figure 3, head hand model has three measurement points to need test, and model bottom has four angles.As shown in Figure 4, the utility model has 12 pilot holes.By model bottom angle and 4,6,10, No. 12 pilot hole compact siro spinning technology during thermometrically point 1, by model bottom angle and 2,5,9, No. 11 pilot hole compact siro spinning technology during thermometrically point 2, by model bottom angle and 1,3,7, No. 9 pilot hole compact siro spinning technology during thermometrically point 3.Model is fixed on and after on fixture, its entirety is put into antenna measurement system and can test, as shown in Figure 5.
By reference to the accompanying drawings exemplary description is carried out to the utility model patent above; the realization of obvious the utility model patent is not subject to the restrictions described above; as long as have employed the various improvement that method is conceived and technical scheme is carried out of the utility model patent; or the design of the utility model patent and technical scheme directly applied to other occasion, all at protection domain of the present utility model without to improve.
