Description

The housing of radiation fan

Technical field

The utility model relates to the radiation fan art, refers in particular to a kind of casing structure of radiation fan.

Background technique

As everyone knows, radiation fan is fixed in the computer housing corresponding to the vent position place by its housing, the electronic parts and components ambient heat is waved is dissipated to outside the ventilated port by driving the flabellum running, and then realize the purpose of heat radiation; At present, limited because of the space, location in the computer housing, more and more pay attention to the integrity of each assembly in the industry, with regard to radiation fan, the power line of making every effort to flabellum can closely cooperate with housing, and then makes seem in appearance neat, aesthetic property; And the flabellum power line of traditional radiation fan is normally fixed in the binding mode, so must remove binding earlier on safeguarding and can operate, so the comparatively trouble that seems, some inconvenience operates; Given this, the clamping structure of the blower-casting of each pattern is also constantly proposed in the industry thereupon.

See also the casing structure of the disclosed radiation fan of Chinese patent ZL03242576.7, ZL03261849.2, the former imbeds power line in the wiring groove of being offered, and there is no other fixed component, causes power line easily to get loose or the phenomenon that falls of breaking takes place; The latter is located at the body outer side surface and arranges power line corresponding to the metallic channel of the second guide portion position by one, be located at this body by one again and stop power line to be deviate from corresponding to the blocking sheet on this metallic channel, but power line still can be deviate from by the breach from blocking sheet; Therefore, the mode of above-mentioned various radiation fan fixed power source lines all can deviate to influence that outward appearance is neat because of power line, planarization and increase defective products and take place, so the housing of the present radiation fan existence space of demanding urgently improving still in use.

The model utility content

The utility model is at the existing disappearance of above-mentioned known techniques, and main purpose is to provide a kind of housing of radiation fan, and it can guarantee that power line compacts, entirely arranges, makes integral body seem more neat, attractive in appearance, and prevents that the power line phenomenon that gets loose from taking place.

For realizing above-mentioned purpose, the utility model is taked following technological scheme:

A kind of housing of radiation fan, comprise a fan frame, these fan frame central authorities form a flabellum holding cavity, middle position at holding cavity is provided with a reference block, offers wire outlet hole on this reference block, is provided with many connecting rods in the outer rim of this reference block and the edge wall one of holding cavity, be concaved with a wiring groove at least one connecting rod, the inner end of this wiring groove is communicated with wire outlet hole, and the outer end is connected with the gap slot that the edge wall of holding cavity is offered, and is embedded with the card line plug that a chucking power line is used in this gap slot.

This card line plug comprises a plug body, and this plug body one pleurapophysis is stretched a guiding rib is arranged, and opposite side then protrudes out the arc fixture block of a gradually-reducing shape, and this guiding rib is stuck in the opening of gap slot; On plug body, be horizontally set with a trip that can catch on the edge wall lower surface of holding cavity with respect to the guiding rib position.This card line plug is a plastic cement material.

The utility model is compared with known techniques, when being to accommodate the flabellum power line by wiring groove, its advantage directly the flabellum power line is tightened by card line plug, its simple operation, and reach again make between power line and housing form compact, smooth state, and then prevent that the power line phenomenon that gets loose from taking place, and also seem more neat, attractive in appearance.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

See also Fig. 1 to shown in Figure 4, a kind of housing of radiation fan comprises a fan frame 1, wherein:

These fan frame 1 central authorities form a flabellum holding cavity 11, middle position at holding cavity 11 is provided with a reference block 12, offer wire outlet hole 121 on this reference block 12, be provided with the connecting rod 13 of four arc shapes, the wherein holding cavity 11 of this pedestal, reference block 12 and connecting rod 13 one-body molded formation fan frames 1 in edge wall 111 one of the outer rim of this reference block 12 and holding cavity 11; On an above-mentioned wherein connecting rod 13, be concaved with a wiring groove 131, the inner end of this wiring groove 131 is communicated with wire outlet hole 121, the outer end is connected with the gap slot 112 that the edge wall 111 of holding cavity 11 is offered, and is embedded with the card line plug 2 that a chucking power line is used in this gap slot 112.

See Fig. 3, this card line plug 2 is one-body molded by plastic material, and it comprises a plug body 21, and these plug body 21 1 pleurapophysis are stretched a guiding rib 22, has been horizontally set with a trip 24 with respect to guiding rib; The opposite side that is positioned at plug body 21 is equipped with gradually-reducing shape arc fixture block 23, this guiding rib 22 clogs in the opening 113 (wire outlet) of gap slot 112, and guide plug body 21 simultaneously and slide,, can utilize arc fixture block 23 to tighten power line more because of plug body 21 more down slips into.The meeting overhead kick is in the lower surface of edge wall 111 after above-mentioned each member chucking power line for above-mentioned trip 24, in case the anti-loose phenomenon of detent plug takes place, extremely the beginning reaches the purpose that does not get loose extremely eventually.

In conjunction with shown in Figure 5, be the structural representation of the utility model Application Example again; Wherein, flabellum 3 is assembled in the holding cavity 11 of fan frame 1, and power line 4 one ends and flabellum 3 windings, the then affixed terminal plug 5 of the other end, wherein, after power line 4 and flabellum 3 windings along passing in the wire outlet hole 121 of reference block 12, imbed in the wiring groove 131 that is arranged with on the connecting rod 13, pass then in the gap slot 112 that edge wall 111 offers and stretch out, and then finish the layout of power line 4; After power line 4 arranges, the plug body 21 of card line plug 2 is pressed into, guiding rib 22 then slips into along opening 113 guidings of gap slot 112, because the external insulation layer of power line 4 has soft shrinkage character, it is after firmly being pressed into of plug body 21, guiding rib 22 clogs the opening 113 (wire outlet) of gap slot 112, plays the guide securement effect; And fixture block 23 blocks power line 4 tight more when plug body 21 more down slips into, simultaneously further can be by the trip overhead kick in the lower surface of edge wall 111, in case the anti-pine of detent plug guarantees to reach all the time the purpose that does not get loose after the chucking.

Certainly, the line of power line directly varies, the thickness of card line plug is fixed, can both tighten in order to control big or small line footpath, can be controlled by the exit width size of this wiring groove, the size herein of fan frame is different because of the line of power line footpath, and can make an amendment slightly according to actual needs to reach unified purpose, to have solved because of power line not of uniform size the bad trouble and worry that gets loose is arranged.

When being to accommodate the flabellum power line by wiring groove, the utility model design focal point directly the flabellum power line is tightened by card line plug, its simple operation, and reach again make between power line and housing form compact, smooth state, and then prevent that the power line phenomenon that gets loose from taking place, and also seem more neat, attractive in appearance.

The above, it only is the preferred embodiment of the housing of a kind of radiation fan of the utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
