Description
Technical field
This utility model relates to power tube technique for fixing, especially relates to a kind of small size, high reliability, perfect heat-dissipating
The fixing device of power tube.
Background technology
Power tube caloric value in the driver of motor is big, needs to ensure heat radiation with radiator good contact.?
In actual product, in order to completely attach between guaranteed output pipe and radiator, gas of not leaving a blank, often increase by one layer of heat conductive silica gel
Sheet, it is therefore desirable to ensure certain contact pressure.But printed circuit board (PCB) thinner thickness, the intensity of material is poor, is easily deformed, as
Ensure in the case of where controlling the deformation of printed circuit board (PCB) that enough contact pressures are the difficult points in product design.
Existing design has 2 kinds: 1) directly use screw to connect printed circuit board (PCB) and dissipate in power tube center
Hot device, it is provided that the pressure needed for power tube heat radiation.The shortcoming of the program is that the material of main part of printed circuit board (PCB) is generally FR-4,
Elastic modelling quantity is less, simultaneously thinner thickness, is easily deformed, thus damages internal copper layer, causes product failure.Simultaneously because FR-4
Material stiffness is poor, so power tube discontinuity, radiating effect is poor, the most fragile heat-conducting silica gel sheet.2) hardness is used very
Low heat-conducting silica gel sheet, utilizes the deflection that it is big, so that needing the pressure provided significantly to reduce.The shortcoming of the program is
Causing small product size to increase, simultaneously because need the pressure provided to reduce, the applying moment of torsion of screw diminishes, and screw may be caused easy
Come off.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and a kind of power tube is provided
Fixing device.
The purpose of this utility model can be achieved through the following technical solutions:
The fixing device of a kind of power tube, for being fixed between panel and radiator by power tube, described is fixing
Device includes monoblock type press strip, and this press strip includes the parts of plastics being connected with panel and the metal part being connected with radiator.
Described metal part is provided with the through hole for installing screw, is fixed on a heat sink by power tube by screw.
Described parts of plastics is provided with the telescoping structure that press strip embeds panel.
Insulating heat-conductive sheet it is provided with between described power tube and radiating tube.
Insulating heat-conductive sheet it is provided with between described power tube and press strip.
Described insulating heat-conductive sheet is heat-conducting silica gel sheet.
Compared with prior art, this utility model has the advantage that
1) avoid printed circuit board (PCB) and bear bigger pressure, thus cause deflection big and the fracture of internal copper layer；
2) still using the heat-conducting silica gel sheet that deflection is little, screw needs the moment of torsion applying to strengthen, difficult drop-off；
3) press strip is embedded between printed circuit board (PCB) and power tube, the most additionally increases volume, simultaneously press strip add insulation away from
From, improve pressure grade, reduce the area of printed circuit board (PCB)；
4) the all-in-one-piece structure of press strip is easily installed, and improves production efficiency.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model；
Fig. 2 is the structural representation after this utility model panel is removed；
Fig. 3 is the partial enlarged drawing of this utility model press strip.
Wherein 1 is panel, and 2 is radiator, and 3 is press strip, and 4 is power tube, and 5 is screw, and 6 is parts of plastics, and 7 is metal
Part, 8 is heat-conducting silica gel sheet.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is a part of embodiment of the present utility model rather than all implements
Example.Based on the embodiment in this utility model, those of ordinary skill in the art are institute on the premise of not making creative work
The every other embodiment obtained, all should belong to the scope of this utility model protection.
As Figure 1-3, this utility model fixing device includes the press strip 3 for constant power pipe 4, and press strip 3 is whole
Body formula, including parts of plastics 6 and metal part 7；Have the through hole for installing screw 5 in metal part 7, parts of plastics have by
Press strip embeds the telescoping structure of panel 1；The screwed hole for installing screw 5 is had on radiator 2.
Between power tube 4 and panel, place press strip 3, use screw 5 to be fixed on radiator 2 by power tube 4；In merit
Place an insulating heat-conductive sheet between rate pipe and radiator, between power tube and press strip, place an insulating heat-conductive sheet；Wherein
Insulating heat-conductive sheet is heat-conducting silica gel sheet 8.
Use technique scheme, by press strip independent constant power pipe, closing for providing between power tube and radiator
While suitable contact pressure, it is to avoid printed circuit board (PCB) bears bigger pressure, it is to avoid the printed circuit board (PCB) being likely to result in
Deformation and the fracture of internal copper layer；Metal part good rigidly, screw directly applies moment thereon, and power tube can be made to be subject to
Power is uniform；Press strip entirety can be embedded on the through hole of printed circuit board (PCB), at assembling product by the telescoping structure of parts of plastics
Time makes an appointment, and improves efficiency, and the most all-in-one-piece infrastructure cost is relatively low.Owing to press strip is monolithic construction, parts of plastics is outstanding
It is that sleeve part adds insulation distance, improves pressure grade, reduces the area of printed circuit board (PCB), reduces cost.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit to
In this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in various
The amendment of equivalence or replacement, these amendments or replacement all should be contained within protection domain of the present utility model.Therefore, this practicality
Novel protection domain should be as the criterion with scope of the claims.
