Abstract
The utility model discloses a water-proof power supply, which comprises a casing and a circuit board fixed inside the casing. Power semiconductor parts are plugged into the circuit board. Circuit board slots for fixing the circuit board are arranged correspondingly on two lateral boards of the casing. The circuit board is fixed inside the slots of the two lateral boards of the casing. By means of the structure, a gap is reserved between the circuit board and a base board, thereby facilitating radiation. Simultaneously, the power semiconductor parts plugged into the circuit board are closely attached to the inner walls of the lateral boards of the casing, thereby facilitating radiation. In addition, radiating teeth are disposed on the outside of the casing, thereby benefiting heat to be transferred into the air.
Description
Technical field
The utility model relates to a kind of power supply, particularly relates to a kind of waterproof power supply of good heat dissipation effect.
Background technology
Traditional waterproof power supply, comprise housing, described housing is two side plates and the base plate that vertically connects two side plates bottom, the front and back end of described housing is connected with plate washer, described plate washer is provided with the line hole, and the top of described housing is provided with top cover, is provided with wiring board, fin in the described housing, described wiring board is fixed on the base plate, is connected with electronic components such as fin and power semiconductor spare on the described wiring board.This traditional waterproof power supply transfers out after with the heat transferred housing by being arranged on fin in the housing again, the efficient that this structural design is transmitted heat is low, cause the phase mutual interference of electronic element radiating in the housing easily, simultaneously wiring board directly is fixed on the heat radiation that is unfavorable for wiring board on the base plate of housing.
Because the defective that above-mentioned existing waterproof power supply exists, the design people is actively studied innovation, in the hope of founding a kind of waterproof power supply of new structure, makes it have more practicality.
The utility model content
Main purpose of the present utility model is, overcome the defective that existing waterproof power supply exists, and provide a kind of waterproof power supply of new structure, technical problem to be solved is to make its good heat dissipation effect, while economical with materials cost, shell is attractive in appearance, thereby is suitable for practicality more, and has the value on the industry.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.Waterproof power supply according to the utility model proposes comprises housing, and is fixed on the wiring board in the housing, is plugged with power semiconductor spare on the described wiring board, the corresponding wiring board draw-in groove that is provided with fixing circuit board on two side plates of housing.
The purpose of this utility model and solve its technical problem and also can be applied to the following technical measures to achieve further.
Aforesaid waterproof power supply, wherein said power semiconductor spare is close on the inwall of housing side plate.
Aforesaid waterproof power supply, the outer setting of wherein said housing has radiation tooth, and described radiation tooth is distributed on two side plates of housing.
By technique scheme, the utility model waterproof power supply has following advantage at least: wiring board is fixed in two side plate draw-in grooves of housing, adopt the waterproof power supply of this structural design, the base plate of wiring board shrinking away from theshell body is gapped, convenient heat radiation, the power semiconductor spare of pegging graft in the circuit board is close on the inwall of housing side plate simultaneously, convenient heat radiation, the outer setting of housing has radiation tooth, makes things convenient for heat transferred in atmosphere.
In sum, the waterproof power supply of the utility model special construction, it has above-mentioned many advantages and practical value, thereby is suitable for practicality more.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.
Description of drawings
Fig. 1 is the structural representation of the utility model waterproof power supply;
Fig. 2 is the partial enlarged drawing of draw-in groove among Fig. 1.
Embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined utility model purpose is taked, below in conjunction with accompanying drawing and preferred embodiment, to embodiment of the present utility model describe in detail as after.
As depicted in figs. 1 and 2, the waterproof power supply, comprise housing 1, and be fixed on wiring board 2 in the housing 1, be plugged with power semiconductor spare 3 on the described wiring board 2, the corresponding wiring board draw-in groove 4 that is provided with fixing circuit board 2 on two side plates of housing 1, described power semiconductor spare 3 is close on the inwall of side plate, when waterproof power supply in working order the time, power semiconductor spare 3 by the side plate be close to heat transferred to housing 1, the outer setting of housing 1 has radiation tooth 5, and the heat that is delivered on the housing 1 is delivered on the radiation tooth 5 again, and radiation tooth 5 is distributed on two side plates of housing 1.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
Claims (3)
