Description

A kind of card line apparatus of radiator fan housing

Technical field

The utility model relates to a kind of card line apparatus of radiator fan housing, relates in particular to the improvement of axial-flow type radiator fan housing card line apparatus.

Background technology

Along with the continuous development of science and technology, performance, the power of various electronic apparatus all constantly stride forward to requirements at the higher level, and then also increase thereupon of internal temperature, to such an extent as to must adopt auxiliary heat dissipation equipment to lower the temperature.One important component parts---radiator fan is arranged in this radiating mode, with the accelerator of doing air flows, wherein commonly used with axial-flow type radiator fan.

Above-mentioned radiator fan generally can carry the fans drive stator by one and the pedestal of the blast fan that is coupling and be plural form and be evenly distributed in the rib of pedestal outer rim, and is located on the pedestal outer rim and the housing formation that links to each other with rib; In addition, it is clean and tidy fixing for power supply wiring is connected up on its radiator fan, also can on the housing of radiator fan, be provided with the card line apparatus, this card line apparatus generally can be provided with cable clamping interface along a rib wherein, and the power supply wiring that will be positioned at radiator fan embeds and is connected with power interface beyond wherein picking out radiator fan again; At last, in order to make this radiator fan product have compatible widely installation property, its power supply wiring length that is picked out by the electronic part in radiator fan center generally can be reserved long size and be exposed to outside the housing of radiator fan.

But the problem that the card line apparatus of existing radiator fan housing in use exists has:

Install when radiator fan and to be applied to structure and to arrange when being provided with in the sophisticated electronics of having relatively high expectations, long power supply wiring may produce the signal of telecommunication and disturb, and also may be because of rocking the normal operation that hinders self or other dynamic structure part.For this reason, in order to keep the most rational power supply wiring length, the corresponding relation that the concrete outlet of the power supply wiring that position and fan the are set orientation of its radiator fan need be electrically connected with the institute erection unit after all implementing accurate design simultaneously and considering, could be realized.

So towards different use equipment, required its card line apparatus has nothing in common with each other to the concrete outlet direction and the position of power supply wiring on the fan housing.

And the card line apparatus of present radiator fan housing does not possess the designing requirement of as above controlling accurate outlet.

The utility model content

In view of the above deficiency of prior art, the purpose of the utility model design is:

A kind of card line apparatus of radiator fan housing is provided, and this card line apparatus can be drawn power supply wiring from different orientation according to actual environment for use or design needs, and makes the power supply wiring that is positioned at the radiator fan housing keep best length.

For achieving the above object, the utility model has adopted following technical scheme:

Design a kind of card line apparatus of radiator fan housing, the middle part that comprises housing, housing is provided with electric fan, electric fan is connected and fixed on the housing by many ribs, rib is provided with cable clamping interface, after embedding in this cable clamping interface, the power supply wiring of electric fan draws the housing of radiator fan again, its innovation is with improvement

On the housing, the peripheral position of lower surface, and the outer side surface of housing is provided with gathering sill, gathering sill is the groove shape of a strip, the bearing of trend of gathering sill and cable clamping interface form corner structure, embed to be drawn out to again outside the radiator fan housing in this gathering sill by the power supply wiring of drawing in the cable clamping interface and be connected with power interface, can change the outlet direction and the position of power supply wiring thus, the concrete control of the outlet direction of power supply wiring and position, can be by gathering sill and cable clamping interface corner size, the length of gathering sill, and select gathering sill is arranged on the housing, the peripheral position of lower surface, and the first-class composite factor of outer side surface that still gathering sill is arranged on housing, come the actual various needs that power supply wiring has different outlet directions and position that obtain;

The position that its cable clamping interface or gathering sill and housing outer edge intersect also is provided with wire blocking port, wire blocking port is a "T"-shaped incision-like, the power supply wiring of being drawn by cable clamping interface or gathering sill can slip into wire blocking port by the "T"-shaped leftover bits and pieces end opening of wire blocking port and block, and can avoid the power supply wiring can be at the edge of housing play like this;

Also be provided with the Bunch buckle that is one " ㄇ " shape on its housing, be provided with the beamline apertures corresponding with two wedge angles of Bunch buckle on the both sides of cable clamping interface or gathering sill, two wedge angles of Bunch buckle just in time can be inserted in this beamline apertures power supply wiring is fastened, the number of this Bunch buckle and beamline apertures can be decided according to the length of cable clamping interface or gathering sill, its number is many more, it is fastening more that power supply wiring is detained in cable clamping interface or gathering sill, its Bunch buckle and beamline apertures are a kind of flexible connection buttons, when the client changes because of installation environment, can also take off outlet direction and position that Bunch buckle is regulated power supply wiring voluntarily.

Certain fastening in order to realize that Bunch buckle and beamline apertures are more fastening, the wedge angle of above-mentioned Bunch buckle also can be hook shape.

In order further to improve the effect that power supply wiring snaps in wire blocking port, the "T"-shaped leftover bits and pieces end opening of above-mentioned wire blocking port is radial, and power supply wiring just is easy to "T"-shaped leftover bits and pieces end opening by wire blocking port and slides into wire blocking port but be not easy and drop out like this.

In order further to improve cable clamping interface or gathering sill chucking effect to power supply wiring, described cable clamping interface or gathering sill edge of opening place are provided with spacer, spacer be a slice bulk by one side of cable clamping interface or gathering sill to the straight extension of another side and leave certain slit, this gap size is can just in time snap in power supply lead wire cable clamping interface or gathering sill, according to reality chucking needs, spacer can be for one or more.

The beneficial effects of the utility model are:

The card line apparatus of radiator fan housing of the present utility model can be according to the concrete various combination of cable clamping interface, gathering sill, wire blocking port, satisfies various actual environments for use or the design needs are drawn power supply wiring from different directions and position; And by drawing the radiator fan housing by behind wire blocking port, Bunch buckle auxiliary fixing in the embedded groove, and then can also reach compact, smooth, prevent the effect that power supply wiring gets loose or breaks and.
