Abstract
The utility model discloses a power source shell. The power source shell includes a back side plate; a three-dimensional through hole is formed in the back side plate; with the three-dimensional through hole adopted, objects will not pass through the three-dimensional through hole in a manner that the objects are perpendicular to the back plate. According to the power source shell of the utility model, a plane through hole is changed into the three-dimensional through hole, such as a shutter through hole and a vertical through hole, and therefore, external debris can be stopped at the through hole, and can be prevented from falling into a power source module, which can assist in avoiding circuit faults.
Description
Technical field
The present invention relates to a kind of outer casing of power supply, belong to power supply product field.
Background technology
In the various electronic equipments such as computer, the power module part that is all absolutely necessary, it is also the internal module that potential safety hazard is larger simultaneously.In power module, have a large amount of power components, itself caloric value is very large, especially in summer, makes power module internal temperature very high, the Plastic Package of the internal electronic element that very easily ignites.
As shown in Figure 1, existing power supply shell comprises base plate 21 and upper cover plate 22, and both are in conjunction with six faces that form outer casing of power supply.Wherein base plate 21 comprises the back side panel 24 that is positioned at rear side and the front side board 23 that is positioned at front side, and front side board 23 is provided with fan hole 25, is also provided with the plane through hole 26 corresponding with fan hole 25 on back side panel 26.Under the effect of power module fan inside 27, air forms gas channel between fan hole 25 and plane through hole 26, and the heat in power module is taken away.
Yet this plane through hole 26 easily makes outside foreign material directly fall into power module, causes power module internal fault.
Summary of the invention
Goal of the invention: the present invention proposes a kind of outer casing of power supply, prevents that outside foreign material from directly falling into power module by plane through hole.
Technical scheme: the technical solution used in the present invention is a kind of outer casing of power supply, comprises back side panel, described back side panel is provided with three-dimensional through hole, and this solid through hole stops object to pass through three-dimensional through hole in the mode perpendicular to back side panel.
Preferably, described three-dimensional through hole is venetian blind type through hole or vertical through hole.
Preferably, described venetian blind type through hole is formed by adjacent dividing plate, dividing plate vertically extends two tailgates that come and forms by diaphragm body and from diaphragm body two ends, two tailgates equal in length, and the width between tailgate and adjacent diaphragm body is less than the length of tailgate self.
Preferably,, described through hole width is less than or equal to 1mm.
Beneficial effect: the present invention is by changing plane through hole into three-dimensional through hole, and for example venetian blind type through hole, vertical through hole, stop outside foreign material in through hole, prevents that it from falling into power module inside, causes fault.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing power supply shell;
Fig. 2 is the structural representation of the embodiment of the present invention 1;
Fig. 3 is the structural representation of the embodiment of the present invention 2.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment is only not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of various equivalents of the present invention.
Embodiment 1: the primary plane through hole on back side panel 24 arranges venetian blind type through hole.As shown in Figure 2, from the cross-sectional direction of back side panel 24, venetian blind type through hole and back side panel 24 are in angle of 45 degrees.Each through hole is formed by adjacent dividing plate.Dividing plate is by diaphragm body 28, and two tailgates 29 that vertically extend from diaphragm body 28 two ends form.It should be noted that the equal in length of tailgate 29, and the width x between tailgate 29 and adjacent diaphragm body 28 is less than the length of tailgate 29 self.Described width x is 1mm.
If the size of foreign material is greater than described width x, it is directly just stopped and cannot enter through hole by the tailgate 29 of opening part.If instead the size of foreign material is less than described width x, these foreign material directly enter in through hole and the tailgate 29 being positioned in power module stops.Because described width x is less than the length of tailgate 29 self, and the size of foreign material is less than described width x, so the tailgate 29 that foreign material must be positioned in power module after entering through hole stops, and is clamped between this tailgate 29 and diaphragm body 28.So the venetian blind type through hole of this inclination makes outside foreign material directly to enter power module inside by through hole.
Embodiment 2: the primary plane through hole on back side panel 24 arranges vertical through hole.As shown in Figure 3, vertical through hole is continuous " several " font, and through hole is opened in the plane vertical with back side panel 24.When outside foreign material are fallen on this vertical through hole, can directly crash into groove 30, or rest on back side panel 24 surfaces, and can not enter power module inside.
Claims (5)
