Shape bearing, described circuit board are placed on described fall
On the vertical arm of shape bearing, the power tube on the described circuit board is arranged to two rows, and the radiating surface of described power tube is attached on the side of two vertical arms on the described bearing.
The technical problem that the present invention solves can also take following technical scheme to realize: described two are fallen
The shape bearing connects with connecting copper bar, and described connection copper bar is fixed on the adjacent vertical arm of described two bearings, and its side is " L " type; Described base plate is provided with collets, and the other end of described connection copper bar is fixed on the described collets; Be provided with empire cloth between described bearing and the described base plate; Described bearing is provided with spring leaf, and the cross sectional shape of described spring leaf is " √ " type, and claw-like is arranged in its upper end; The support arm of described bearing is provided with projection; Be provided with groove around the described loam cake bottom surface, be provided with sealing ring in the described groove; Described loam cake is provided with the hole.
The present invention compared with prior art has significant advantage and beneficial effect, is embodied in the following aspects:
1. the present invention adopts bearing and base plate to help the power tube heat radiation, because the thickness of bearing and base plate is bigger, thermal diffusivity is improved greatly.
2. adopt spring leaf extruding power tube, make production technology oversimplify, improved production efficiency, also reduced product cost and management cost simultaneously.
3. adopt " √ " shape spring leaf extruding power tube, power tube better is fitted on the bearing, better realize fixing circuit board, also very helpful to heat radiation.
4. be provided with empire cloth between bearing and the base plate, the security performance of controller has been improved widely.
5. bearing is provided with projection, is used to limit the position of insulating material, makes more convenient to operately, and order of accuarcy improves greatly.
6. connect copper bar two bearings are linked together, make that the structure of controller is more stable, shockproof properties has obtained reinforcement, thereby the coefficient of safety of controller also is improved.
7. adopt sealing ring to carry out waterproof, make production simple and fast more, saved manpower and materials, reduced the cost of product than traditional silica gel of smearing.
