Abstract
The utility model relates to a novel device for installing a power tube of a controller of a brushless electric machine. The device comprises a radiator, insulating cloth, a spring mechanism, a printed circuit board and the power tube, wherein the spring mechanism is welded in a fixed hole on the printed circuit board; the power tube is welded on the printed circuit board; the lower surface of the power tube is closely connected with the spring mechanism; and the upper surface of the power tube is closely connected with the insulating cloth which is closely connected with the radiator. Compared with the prior art, the device has the advantages of simple installation, good radiating performance, low failure rate, etc.
Description
Technical field
The utility model relates to the erecting device of electric machine assembly, especially relates to a kind of novel brushless motor controller power tube erecting device.
Background technology
At present, many brushless motor controller power tubes are installed and are existed the assembling complicated problems, cause emergent power pipe and radiator short circuit easily in assembling process, cause power tube damage etc.Present mounting means is to use 6 cover screw combinations, comprises screw, spring washer, insulating washer, empire cloth; Assembling need be opened six screws in accurate position on radiator.In the time of assembling, require the alignment of the hole site of the installing hole of power tube and radiator, the dynamics of tightening of screw is suitable, otherwise power too conference is damaged empire cloth and insulating washer, and the too little meeting of power radiating effect is poor.Therefore in installation process, be easy to occur assembly problem.
Summary of the invention
The purpose of this utility model is exactly to provide the novel brushless motor controller power tube erecting device that a kind of thermal diffusivity is good, failure rate is low for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of novel brushless motor controller power tube erecting device, it is characterized in that, this device comprises radiator, empire cloth, spring mechanism, printed circuit board (PCB), power tube, described spring mechanism is welded in the fixing hole on the printed circuit board (PCB), described power tube is welded on the printed circuit board (PCB), the lower surface of described power tube is close to spring mechanism and is connected, and the upper surface of described power tube is close to empire cloth and is connected, and described empire cloth is close to radiator and is connected.
Described spring mechanism is the spring steel plate rolled-up stock.
Compared with prior art, the utlity model has following advantage:
One, mounting means is simple: spring mechanism and power tube all are welded on the printed circuit board (PCB), need not screw between power tube and the radiator, have saved a large amount of installation times.
Two, good heat dissipation effect: invention medi-spring mechanism is formed by the spring steel plate compacting, between energy guaranteed output pipe and the radiator suitable pressure is arranged all the time, and this pressure had both guaranteed radiating effect, can not cause the empire cloth breakage again, caused fault.
Three, failure rate is low: owing to no longer adopt screw, simplified production technology; Being connected of radiator and power tube is more reliable, and the power tube heat radiation is guaranteed; By this two aspect the failure rate of controller is reduced greatly.
Description of drawings
Fig. 1 is the structural representation of a kind of novel brushless motor controller power tube erecting device of the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of novel brushless motor controller power tube erecting device, it is characterized in that, this device comprises radiator 1, empire cloth 2, spring mechanism 3, printed circuit board (PCB) 4, power tube 5, described spring mechanism 3 is welded in the fixing hole on the printed circuit board (PCB) 4, described power tube 5 adopts the TO-262 encapsulation, described power tube 5 is welded on the printed circuit board (PCB) 4, the lower surface of described power tube 5 is close to spring mechanism 3 and is connected, the upper surface of described power tube 5 is close to empire cloth 2 and is connected, and described empire cloth 2 is close to radiator 1 and is connected.Described spring mechanism 3 forms for the spring steel plate compacting.
The present invention has utilized the favorable elasticity of spring mechanism 3, makes to guarantee between power tube 5 and the radiator 1 that the suitable power of being close to is arranged, thereby has guaranteed the normal heat radiation of power tube 5, and simultaneously, mounting means is simple, and the fault of having avoided the assembling in the production process to cause takes place.Use this structure, heat radiation reliability that can guaranteed output pipe 5 has reduced failure rate again.
