Description

Computer power source supply device circumscribed structure

Technical field:

The utility model relates to the computer components technical field, refers in particular to a kind of computer power source supply device circumscribed structure.

Background technology:

The existing power supply unit that is installed in the host computer for the ease of the computer assembling, is generally drawn some bundle power leads by the power supply unit body interior, so that connect computer system or some peripheral equipments.Such structure not only has big, the messy sense of volume and weighs, and is unfavorable for arrangements of elements, and assembling and removal efficiency are not high, and use too much power lead, and the cost height also causes meaningless waste.

Summary of the invention:

The purpose of this utility model is to overcome the defective of prior art, and a kind of compact conformation is provided, and is beneficial to assembling and dismounting, the power supply unit that volume is little.

For achieving the above object, draw several external female/males on the supply main body of the present utility model, this external female/male electrically connects the power circuit of main body, and female/male is directly fixed on the sidewall of main body.

The utility model also can be done following improvement, and external female/male is the rounded convex structure, forms helicitic texture in the outer peripheral edges of convex section and fixes for the line body interlocking of pegging graft with it; Perhaps external female/male is done squarely evagination structure, can increase buckle structure on its edge and be cooperated fixing.

Described main body cover is made up by upper and lower covers, on upper and lower covers, be equipped with the fan mounting hole and, and around the fan mounting hole of loam cake and the equal punching out in other side of loam cake netted open-end hole is arranged.

Adopt such structure, supply needn't be drawn too much power lead, leaves several female/males for user's use of pegging graft, and reduced volume is ease of assembly also, and cost is low.

Another advantage of the utility model is the structural design by upper and lower covers, as fan being installed and being increased netted open-end hole, realizes the effect that the supply main body can better be dispelled the heat, and guarantees the supply operate as normal.

Embodiment:

See shown in the accompanying drawing 1～4, the utility model comprises the main body 10 of power supply unit, main body 10 inside are equipped with corresponding circuit board and electric elements, on main body 10, draw several external female/males 20, external female/male 20 electrically connects the power circuit of main body 10, and female/male 20 is directly fixed on the sidewall of main body 10.

Shown in Fig. 1,2, external female/male 20 is the rounded convex structure, forming helicitic texture in the outer peripheral edges of convex section fixes for line body 30 interlockings of pegging graft with it, at this moment movable line body 30 heads of pegging graft have one to contain the nut interlocking of internal thread on the thread segment on female/male 20, compactedness between the contact in enhancing female/male 20 and the webge contact of line body 30 improves the contact effect.

External female/the male 20 of on the main body 10 several can be designed to dissimilar interfaces, can use simultaneously, also can selectively use, and is beneficial to assembling, has avoided the some bundle power leads of existing supply no matter whether to use, and all deposits in the situation in the host computer.

Shown in Fig. 3,4, external female/male 20 is square outer male structure, also be square to line body 30 the end of a thread of inserting with it at this moment, on female/male 20 edges, also can increase buckle structure cooperated fixing, assembling and dismantle quite convenient.

Shown in Fig. 5～11, supply main body 10 shells are by " door " shape loam cake 11 and 12 combinations of " door " shape lower cover, on upper and lower covers, be respectively equipped with fan mounting hole 111 and 121, and around the fan mounting hole 111 of loam cake 11 and the loam cake equal punching out in 11 other sides netted open-end hole 112 is arranged.Offer fan mounting hole 121 on one side of lower cover 12, set installation for external female/male 20 and offer respective through hole on the another side.During use, the fan on the upper and lower covers cooperates heat radiation, and netted open-end hole 112 plays the effect of accelerating cross-ventilation and strengthening dispelling the heat, better heat-radiation effect.

The utility model has strengthened its practicality by structural improvement effectively, compact conformation and be convenient to assembling, the situation of also having avoided too much power lead to draw.Certainly; the embodiment of the above only is preferred embodiment of the present utility model; be not to limit practical range of the present utility model,, all should be covered by in the protection domain of the present utility model so the equivalence that all shapes according to the utility model, structure and principle are done changes with this.
