Being described in detail as follows of the utility model preferred embodiment:

To (C), fan wire-management device 10 of the present utility model comprises with reference to Fig. 1 (A):

One bottom 11;

Two side faces support sector 12 and 12 ' is perpendicular to 11 both sides, bottom; And

Two baffle portion 13 and 13 ' are positioned at 11 tops, bottom, and each baffle portion 13 and 13 ' is connected to respectively and perpendicular to side support sector 12 and 12 '.

Form a passage between the bottom 11 of fan wire-management device 10, two side faces support sector 12 and 12 ' and two baffle portion 13 and 13 ', electric wire 80 promptly enters among this passage after the motor of fan connects.Relative position with Fig. 1 (B), the upper left side of the lower right side of top-right side support sector 12 contact side of electric wire 80 (promptly with) and the side support sector 12 ' of the lower left contact side of electric wire 80 (promptly with) is parallel to each other, and its parallel distance be slightly less than electric wire 80 external diameter and, therefore electric wire 80 can be twisted between side support sector 12 and 12 ' a little.Because electric wire 80 is to place among the wire-management device 10 with circuitous a little state, but not as known wire-management device be mode with straight line, therefore produce mutual acting force between the side support sector 12 of wire-management device 10 and 12 ' meeting and the electric wire 80, comprise positive acting power and friction force.The source of this acting force is for electric wire 80 is being twisted under the state spontaneous restoring force.Because the existence of this acting force; make electric wire 80 more firm in wire-management device 10; and when external force is pullled electric wire 80; can be resisted by this acting force, be made wire-management device 10 and known wire-management device in comparison, be had more function fixing to electric wire 80 and protection; unlikely when fan running; because of vibrations or windage get loose or be involved in the fan, and when the assembling computer system, can not cause spot welding place of electric wire 80 on fan motor to come off because of pullling.

Baffle portion 13 and 13 ' function be not for the restriction electric wire can be stuck up by the top of wire-management device 10.Yet, because side support sector 12 and 12 ' and electric wire 80 between have friction force, in fact and be difficult for producing sidesway with respect to side support sector 12 and 12 ' therefore if selected suitable physical dimension, electric wire 80.Therefore, electric wire 80 might not touch baffle portion 13 and 13 ' in fact, being the function of baffle portion 13 and 13 ', is not that electric wire is to make a circulation in order to cause as side support sector 12 and 12 ' in this embodiment, and only for guaranteeing that electric wire 80 can more stably be fixed in the wire-management device 10.If the circuitous degreeof tortuosity of electric wire 80 is quite big, make the friction force between itself and side support sector 12 and 12 ' very big, then can be with baffle portion 13 and 13 ' or one of them omission, and can not influence the function of this wire-management device 10.

That is, via the physical dimension that changes in the wire-management device, can adjust the circuitous twisting situation of electric wire among wire-management device, and then determine the size of acting force between electric wire and the wire-management device.If acting force is big more, then wire-management device is just good more to the fixing of electric wire and protection effect in theory.Yet the excessive distortion of making a circulation will have the possibility of the assembling of being difficult for even damage electric wire; therefore should select a suitable physical dimension combination; make the relativeness of side support sector and baffle portion in the wire-management device, the fixing and protection to electric wire has the best can not cause damage to electric wire or fan again.

Because electric wire 80 is to place wire-management device 10 with circuitous a little state, makes it produce acting force naturally, does not fix electric wire so must not add extra element, that is, wire-management device 10 can one-body moldedly be made.So can reduce the cost of material, processing and assembling.

With reference to Fig. 2 (A), another kind of fan wire-management device 20 of the present utility model comprises:

One bottom 21;

Two side faces support sector 22 and 22 ' is perpendicular to 21 both sides, bottom; And

Two baffle portion 23 and 23 ', this baffle portion 23 are positioned at 21 tops, bottom, and are connected to and perpendicular to side support sector 22, and this baffle portion 23 ' then is connected to and perpendicular to bottom 21.

Not existing together of fan wire-management device 20 and aforementioned fan wire-management device 10 maximums is the surface of contact and the on-plane surface of bottom 21 and electric wire 80, but comprises a bossing.With reference to Fig. 2 (B) and since the surface of contact of baffle plate 23 and electric wire 80 and bottom 21 projectioies partly with the parallel distance of the surface of contact of electric wire 80, less than the external diameter of electric wire 80, make electric wire 80 in wire-management device 20, can produce another kind of circuitous state.The circuitous state of this kind is identical with the function of the circuitous state of aforementioned wire-management device 10; promptly utilize electric wire 80 being twisted under the state; spontaneous restoring force; make electric wire 80 more firm in wire-management device 20; and when external force is pullled electric wire 80; resisted by this acting force; make wire-management device 20 and known wire-management device in comparison; have more function fixing to electric wire 80 and protection; and when fan running; not reason vibrations or windage and get loose or be involved in the fan, and when the assembling computer system, can not cause spot welding place of electric wire 80 on fan motor to come off because of pullling.

With aforementioned first embodiment similarly, in fact and be difficult for producing sidesways with respect to baffle portion 23 and bottom 21 if selected suitable physical dimension, electric wire 80.Therefore, electric wire 80 might not touch side support sector 22 and 22 ' in fact, being the function of side support sector 22 and 22 ', is not for causing electric wire circuitous, and only for guaranteeing that electric wire 80 can more stably be fixed in the wire-management device 20 in this embodiment as baffle portion 23 and bottom 21.If the circuitous degreeof tortuosity of electric wire 80 is quite big, make the friction force of 21 of itself and baffle portion 23 and bottoms very big, then can be with side support sector 22 and 22 ' or one of them omission, and can not influence the function of this wire-management device 20.

And because electric wire 80 places wire-management device 20 with circuitous a little state, make it produce acting force naturally, so and aforementioned wire-management device 10 in the same manner, wire-management device 20 must not add extra element and fix electric wire, that is, wire-management device 20 can one-body moldedly be made.Use the cost that reduces material, processing and assembling.
