Expect cost and production cost.
Summary of the invention
Exempt from screw peace the purpose of this utility model is to provide a kind of power amplifier chips in vehicle audio power amplifier
Assembling structure, the described this power amplifier chips in vehicle audio power amplifier exempt from screw mounting structure and to solve the prior art
Power amplification IC circuit in middle power amplifier installs the undesirable technical problem of fixed form.
This power amplifier chips in vehicle audio power amplifier of the utility model exempt from screw mounting structure, including dissipate
Hot device, PCB printed circuit board, power discharging IC integrated circuit, which is characterized in that be provided with printed circuit card in the middle part of the radiator
Slot, the PCB printed circuit board are mounted in radiator by the printed circuit board card slot, the power discharging IC integrated circuit peace
On PCB printed circuit board, it is provided with guide rail structure below the bottom radiator, power discharging IC integrated circuit, it is described to lead
It is provided with elastic circlip in rail structure, the elastic circlip is intermediate to have arch protrusion and both ends are with being folded up flange
W-shape, is set as sliding pair between elastic circlip and radiator, the glide direction of the sliding pair is parallel to PCB printing electricity
Road plate, the arch protrusion among elastic circlip are located at the lower section of power discharging IC integrated circuit and by PCB printed circuit board by power amplifier
IC integrated circuit is pressed on the radiator above power discharging IC integrated circuit, and elastic circlip both ends bottom both ends are respectively downward
Equipped with a positioning protrusion, there are two location hole, elastic cards for the bottom setting of the guide rail structure immediately below power discharging IC integrated circuit
The positioning protrusion of spring be respectively inserted into one described in location hole, the spacing of two location holes is less than elastic circlip in a free state
Spacing between two positioning protrusion, when installation, push the elastic circlip mobile until two convex card liftings in guide rail
Enter location hole, due to the positioning pitch of holes be less than the positioning protrusion spacing thus the elastic circlip can deformation occurs and to
It is upper to jack up the PCB printed circuit board, fit closely the power discharging IC integrated circuit with the spreader surface.
Further, the location hole is longitudinally arranged in a staggered manner and the positioning protrusion is also accordingly longitudinally arranged in a staggered manner.
Further, the first side plate and the second side plate, and first side plate and second side is arranged in the radiator both ends
Ventilation hole is set on plate.
The working principle of the utility model is：Deformation occurs for elastic circlip to make its height increase, and sends out pcb board surface
Raw upward flexible deformation makes to become interference fit from clearance fit between radiator at the top of power discharging IC to make power discharging IC and dissipate
It remains and fits closely between hot device surface, reach good heat dissipation effect.
The utility model compares with prior art, effect be actively and it will be evident that the utility model to IC bracket
Structure optimizes, and using the elastic circlip fastening means for exempting from screw, which need not reserve rack mounting apertures on pcb board,
Directly elastic circlip is fixed in the guide rail of radiator, this structure design had both improved the utilization rate of pcb board, reduced
The difficulty of electronics wiring under conditions of not increasing cost effectively improves the assembling structure of power discharging IC and radiator,
Card slot and guide rail structure are designed on radiator, simplify installation procedure ensure that heat dissipation effect simultaneously.
