The technical problem that the present invention solves can also take following technical scheme to realize: described two are fallen " π " shape bearing with connecting copper bar connection, and described connection copper bar is fixed on the adjacent upright 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 described collets; Empire cloth is provided with between described bearing and 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; The surrounding of described upper cover bottom surface is provided with groove, is provided with sealing ring in described groove; Cover on described and be provided with 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 power tube heat radiation, because the thickness of bearing and base plate is comparatively large, improves greatly thermal diffusivity.
2. adopt spring leaf Squeezed splice pipe, production technology is simplified, improves production efficiency, also reduce product cost and management cost simultaneously.
3. adopt " √ " shape spring leaf Squeezed splice pipe, power tube is better fitted on bearing, better realizes fixing circuit board, also very helpful to heat radiation.
4. be provided with empire cloth between bearing and base plate, the security performance of controller is greatly increased.
5. bearing is provided with projection, for limiting the position of insulating material, make more convenient to operate, order of accuarcy improves greatly.
6. connect copper bar to be linked together by two bearings, make the structure of controller more stable, shockproof properties obtains reinforcement, thus makes the coefficient of safety of controller have also been obtained raising.
7. adopt sealing ring to carry out waterproof, make production simple and fast more, save manpower and materials than traditional silica gel of smearing, reduce the cost of product.
