Traditional module frame material adopts carbon steel material or stainless steel material, connects the process using welding procedure.For example, like Fig. 1 to carbon steel or stainless steel module frame 1 shown in Figure 3, the box type frame structure that this module frame 1 is welded by carbon steel or bar section of stainless steel.Welded nut 2 on four vertical profiles of module frame 1 is used for fixing the secondary circuit of power module; Welded nut 3 on the section bar on module frame 1 end face four limits is used for fixing the primary circuit of power module; Be provided with vertical steel plate in module frame 1 inside, and perforate on steel plate, be used for the primary circuit of auxiliary fixing module.
There is following shortcoming in the structure of above-mentioned conventional frame:
1. antimagnetic poor performance: the carbon steel material price is low, is easy to processing, but has high magnetic conductivity, is not suitable for using under the high frequency electric source complex electromagnetic environments.
2. structure is dumb: owing to adopt technologies such as lead frame, welded nut, perforate, the structure of framework can not be adjusted arbitrarily according to the variation of module.
3. weight is big, cost is high: carbon steel and stainless steel material weight are big, and the cost of stainless steel material is too high.
4. machining property is poor: stainless steel material has antimagnetic advantage, but because hardness is big, machining property is poor.

The purpose of the utility model can realize through following technical measures:
A kind of high frequency power module framework; The box type frame structure that this module frame is formed by the section bar overlap joint; Adopt special-purpose angle sign indicating number to connect between the said section bar, said section bar is the square column type, and the four sides of square column is equipped with the groove that moves towards extension along length; Receive in the opening of said groove, being equipped with in the said groove can be along the nut of groove slip.Nut cooperates with securing members such as outside bolt, screw rods as built-in fitting, primary circuit that just can stuck-module, secondary circuit etc.Nut just is fixed on certain position of section bar groove after bolt, screw rod with the outside lock.
Said section bar inside is provided with the hollow duct.
Said section bar is an aluminium section bar.
Said module frame is formed by 12 section bars overlap joint altogether, adopts overlap joint angle sign indicating number to interconnect between per two section bars that intersect 90 degree.
Said module frame is provided with the loose-leaf that is used for the installation and control case.
Said module frame is provided with handle.
Said module frame bottom is provided with castor.
The utility model contrast prior art has following advantage:
1, this module frame had both antimagnetic, machining property good, intensity is high, in light weight, advantage that cost is low;
2, this module frame adopts lap joint process, has flexile advantage, to the equal ability of the module well adapted of different size;
3, the aluminium section bar groove of this module frame is embedded in sliding nut, can fix, support multiple device neatly;
4, the metal material of the aluminium section bar of this module frame can repeated multiple times reclaim, and has more the advantage of environmental protection than carbon steel, stainless steel material.
