Abstract

The invention discloses a power supply unit shell. The power supply unit shell comprises a first shell and a second shell which have a U-shaped sheet shape and comprise a middle section and two wing sections respectively; the parts, close to two side end edges, of inner side surfaces of the two wing sections of the first shell are provided with a positioning groove respectively and the inner side surfaces are provided with two convex ribs arranged between two positioning grooves; an inner baffle block is protruded on each convex rib facing the adjacent positioning groove; the second shell is sleeved on the first shell; the two wing sections of the second shell are arranged on the middle section of the first shell and on one of the side end edges of the two wing sections of the first shell, and positioning bumps which are clamped in the positioning grooves of the two wing sections of the first shell are protruded on the two wing sections of the second shell; an outer baffle block which is positioned between the inner baffle block and the wing section of the first shell, is pressed against the inner baffle block and corresponds to each convex rib is protruded on the inner side surfaces of the two wing sections of the second shell respectively; and as the positioning bumps are clamped in the positioning grooves and the inner baffle blocks are pressed against the outer baffle blocks, a phenomenon that the first shell and the second shell are separated from each other under the action of external force can be avoided.

Description

The power supply unit shell

Technical field

The present invention relates to a kind of power supply unit, refer in particular to the shell of power supply unit.

Background technology

Power supply unit is a kind of power supply change-over device, is mainly used in source power supply is converted to being fit to the power supply that various electric equipment products are used, modal for example have alternating current is converted to direct current.

referring to Fig. 4 and shown in Figure 5, be the shell of the power supply unit of a prior art, it has one first housing 40 and one second housing 50, this first housing 40 and the second housing 50 all are U-shaped, has respectively a

stage casing

41, 51 and two

wing panels

42, 52, the first housing 40 and the second housing 50 and with the mutual fit of openend, thereby be surrounded by an accommodation space 60, this accommodation space 60 is in order to arrange as transformer or rectifier (not shown) etc. assembly, and this first housing 40 and the second housing 50 can not separate because of pressurized in order mutually to locate after fit, two wing panel 42 ora terminalis places at the first housing 40 are concaved with positioning ditch 421, correspondence is provided with locating convex block 521 at two wing panel 52 ora terminalis places of the second housing 50, snap in positioning ditch 421 by this locating convex block 521, can reach and make the first housing 40 and the second housing 50 purpose of location mutually.

yet, because the first housing 40 and second housing 50 of the shell of above-mentioned prior art all is U-shaped, its two

wing panel

42, 52 have pliability, easily bend when pressurized, once the wing panel 42 of the either side of a certain housing, 52 pressurizeds and towards accommodation space 60 inner bendings, this

wing panel

42, 52 just can push two wing panels 42 of another housing, 52 open it, and the shell that adopts aforementioned location structure to design, during two wing panel 42 pressurized of its first housing 40, because the locating convex block 521 on two wing panels 52 of the second housing 50 snaps in the positioning ditch 421 of the first housing 40, can stop two wing panels 52 of the second housing 50 to be opened toward the outer side, therefore the second housing 50 can't break away from the first housing 40, but when two wing panel 52 pressurized of the second housing 50, aforesaid location structure also can't stop two wing panels 42 of the first housing 40 to be opened toward the outer side, therefore the power supply unit shell of the prior art has between the first housing 40 and the second housing 50 fixing not firm, easily in use because being subjected to the External Force Acting shortcoming of disengaging mutually.

Summary of the invention

Because the shortcoming that existing first housing of power supply unit shell of aforementioned prior art and the second housing easily break away from mutually, the present invention's expectation solves by the location structure between improvement the first housing and the second housing.

For reaching the foregoing invention purpose, technological means used in the present invention is to provide a kind of power supply unit shell, and it includes:

One first housing, it is the U-shaped sheet that includes one first stage casing and two first wing panels and has a medial surface and a lateral surface, wherein be provided with respectively a location chase adjacent to ora terminalis place, both sides on the medial surface of these two first wing panels, and be respectively equipped with two fins on the medial surface of these two first wing panels, this two fin on each first wing panel and is equipped with an internal stop towards adjacent positioning ditch on each fin between two positioning ditch;

one second housing, it is the U-shaped sheet that includes one second stage casing and two second wing panels and has a medial surface and a lateral surface, the second housing and the mutual fit of the first housing, its two second wing panel arranges respectively a wherein side edge place of the first stage casing of being positioned at the first housing and two first wing panels, be equipped with respectively the locating convex block in the positioning ditch that is sticked on two first wing panels in the ora terminalis place of two second wing panels, and be equipped with an outer baffle block in each fin that corresponds respectively on the medial surface of two second wing panels on two first wing panels, each outer baffle block lays respectively between the internal stop of corresponding fin and the first wing panel and connects with this internal stop.

Better, power supply unit shell of the present invention, can be respectively equipped with a location chase adjacent to ora terminalis place, both sides on the medial surface in the first stage casing of its first housing, and the ora terminalis place of two second wing panels of described the second housing can be equipped with respectively the locating convex block in the positioning ditch that is sticked on this first stage casing.

Better, power supply unit shell of the present invention can be provided with a through hole on its first housing, and can be provided with at least two inserted sheets on the second housing, perhaps can be provided with at least two inserted sheets on its first housing, and can be provided with a through hole on the second housing.

power supply unit shell of the present invention has the positioning ditch identical with the shell of prior art and the location structure of locating convex block, and further increased the location structure of internal stop and outer baffle block, therefore after the first housing and the mutual fit of the second housing, except the shell of the second housing and prior art equally can break away from the first housing, because the internal stop of the fin on two first wing panels of the first housing is connected on the internal stop of the second housing, can stop two first wing panels of the first housing towards opening the direction bending, even so two second wing panel pressurizeds of the second housing, the first housing can thereby not break away from the second housing yet, hence one can see that, and power supply unit shell of the present invention is comparatively firm, even being subjected to External Force Acting also not have the phenomenon that the first housing and the second housing break away from mutually occurs.
