Description
Technical field
It the utility model is related to a kind of elastic construction, more particularly to a kind of spring leaf and pressing device.
Background technology
Existing heating element, such as power transistor, caloric value are bigger, it is necessary to be radiated to it.Prior art is led to
Cross the radiating surface of heating element held against heat sink, good radiating is carried out to heating element so as to realize, to keep heating element to have
Good performance.
Prior art one of which scheme is to be clung to heating element on the radiating surface of radiator by screw, specifically
Come, the heating element is provided with mounting hole, and the radiator is provided with screw, and screw is screwed to the spiral shell of radiator through mounting hole
Kong Zhong, heating element is clung on radiator so as to realize.However, because the nut of screw is compared with the contact surface of heating element
It is small, so as to cause the surface pressure that heating element contacts with the nut of screw very big, so as to be easily damaged heating element；It is additionally, since
Mounting hole is smaller, causes safety distance between screw and heating element not enough, heating element may be caused conductive to scattered via screw
On hot device, so as to cause component damage.Therefore the mode effect of screw in compression heating element is undesirable.
Prior art another kind scheme is clings to heating element on radiator by press strip, and specially press strip can become
Heating element is pushed down in shape, press strip one end, and the press strip other end is fixed on radiator by screw, such a compression mode, the change of press strip
Shape amount can not be too big, and deflection is too big, and press strip can be caused press strip is pressed in heating during being fixed to radiator by screw
Position on device is moved to the edge of heating element, loses effect so as to cause press strip to compress heating element, but if press strip deforms
Amount is little, then the cushion effect of concussion resistibility is smaller, is easily damaged heating element.So as to which such a press strip mode installation difficulty is high, than
More difficult assurance, it is also not ideal；Another mode of texturing for compressing heating element by press strip is to compress two by a press strip
The press strip is set between individual heating element, specially two heating elements, and the left end of press strip pushes down the heating element on the left side, the right side of press strip
Side pressure lives the heating element on the right, is fixed among press strip by screw on radiator, such a mode equally has above-mentioned press strip pressure
The defects of tight heating element mode, moreover, such a mode is because screw is passed through from the gap between two heating elements, so as to two
Safety distance between heating element needs to increase, and heating element is mounted in pcb board (Printed Circuit Board, printing
Wiring board) on, so as to cause the size of pcb board to need to increase, the space waste of pcb board is caused, therefore such a mode is also paid no attention to
Think.
, there is the problem of many in aforesaid way, the fixation for heating element, it is impossible to solve fixed heating element well
Problem.
