Description
Technical field
The present invention relates to electricity field, relate in particular to the power amplifier that is used for hoot device, particularly a kind of vehicle power amplifier IC fixation spring tab.
Background technology
In the prior art, the heat loss power of the IC chip that uses in the power amplifier of hoot device (IC) is bigger, in order to guarantee IC components and parts operate as normal, needs to adopt radiator that it is dispelled the heat.For the heat that makes IC can fully be delivered on the radiator, must adopt the IC fixation spring tab that IC is fixed, make IC ability held against heat sink, guarantee as much as possible being delivered on the radiator of heat on the IC.For heat-sinking capability that improves radiator and the cost that reduces whole power amplifier, available technology adopting is extruded aluminium section bar manufacturing " mouth " shape radiator, and like No. 200820152242.2 patents of China, " mouth " shape radiator is a frame structure.Because there is the face of 4 sealings in " mouth " shape radiator space, has saved parts such as the upper and lower cover plate of power amplifier, (IC one side) do not installed the needed assembly space of IC fixation spring tab at the heat radiator fin back side, can't continue to use the IC fixation spring tab of traditional design.
Summary of the invention
The object of the present invention is to provide a kind of vehicle power amplifier IC fixation spring tab, described this vehicle power amplifier IC fixation spring tab will solve the technical problem that IC fixation spring tab insufficient space is installed at " mouth " shape heat radiator fin back side in the prior art.
This vehicle power amplifier IC fixation spring tab of the present invention is made up of an elastic sheet metal; Wherein, described elastic sheet metal is the П shape, and the middle part of elastic sheet metal is cambered surface; The two ends of elastic sheet metal constitute feet respectively behind the outer lateral buckling of cambered surface; Described feet constitutes stator after the bending laterally again, and described stator all is positioned at same plane, and the outer end of any stator is provided with flanging; Any stator is all to being arranged with a fixing feet; Any described fixing feet is extended formation by elastic sheet metal, and the end of fixing feet is provided with hook-shaped breach laterally, is provided with the tapping screw hole in any stator.
Further, the middle part of elastic sheet metal is provided with a rectangle guide tabs to upside.
Operation principle of the present invention is: two fixing feet in the elastic sheet metal are passed two square holes on the circuit board, and the IC chip of elastic sheet metal from three flanked circuit boards fixed through wave-soldering and circuit board welding then.Be processed with two fixing holes separately after the extrusion molding of " mouth " shape radiator, the cross section of extruding of " mouth " shape radiator is provided with circuit board fixed card slot structure and auxiliary IC fixation spring tab fixed structure.Elastic sheet metal with circuit board along the radiator draw-in groove insert radiator and and radiator fix.Use tapping screw to shoot the tapping screw hole on the elastic sheet metal from the radiator outside then along the fixing hole on the radiator, the tension elastic sheet metal, final elastic sheet metal clings to the IC chip on the madial wall of radiator.The rectangle guide tabs of elastic sheet metal middle part upside; In the circuit board insertion process, cooperated the assembling guide effect with shape of the mouth as one speaks radiator corresponding construction; Shoot in the process at tapping screw, cooperate with the auxiliary IC fixation spring tab fixed structure of radiator propulsive thrust is provided; The help tapping screw is shot, and realizes fixing.Along with the increase that tapping screw is shot the degree of depth, elastic sheet metal moves forward and the IC chip is pressed on the radiator.Guarantee the thrust of shell fragment through the shell fragment deflection of design in advance, the heat transferred of guaranteeing the IC chip is to radiator.
Concrete; Plane, stator place is to the vertical thickness of the vertical range B between the contact-making surface of elastic sheet metal and IC chip less than the IC chip, and after guaranteeing the assembling of elastic sheet metal and IC chip, the shell fragment cambered surface deforms; Produce thrust, guarantee fitting tightly of IC chip and radiator.The flanging of stator outer end can avoid shell fragment shell fragment when packing (or taking-up) into along the radiator inwall face to scrape slotting spreader surface.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention utilizes π shape elastic sheet metal that the IC chip is pressed to radiator inwall; Utilize tapping screw tension elastic sheet metal from the outside of radiator; Solved in the prior art the not enough technical problem of assembly space at the heat radiator fin back side; Make " mouth " shape radiator can extensive use, controlled the cost of radiator.
