Abstract

The utility model provides a fixing device for radiating fins, which comprises a hollow cylinder screw seat, a perforated channel formed at the hollow position, more than two cutting grooves which are arranged at the bottom of the cylinder and are communicated to the channel, a stud which can be inserted in the channel of the screw seat, wherein the stud comprises a cylinder and a barb body, and the tail end of the barb body is slightly bigger than the cylinder. The process that the stud is inserted into the screw seat can be used for distracting the cutting groove by the tail end. Moreover, the barb body is used for butting with the tail end of the channel of the screw seat. Therefore, the radiating fins connected in series in the screw seat are fixed on a system board on a die set of a CPU completely and tightly.

Description

The fixture of groups of fins

The utility model provides a kind of fixture, refers to that especially a kind of assembling is easy, and simple operation does not cause low intensive object to break in the time of fixedly and tool is shatter-proof and the fixture of the groups of fins of insulation.

Be covered with various electric elements on the computer motherboard, each electric elements is as chip, motor, disk drive etc., in each element start process, the capital produces high heat, thereby generally be provided with fan on the computer chassis, be used for the hot gas in the computer chassis is extracted out, influence the steady operation of each electric elements to avoid over-heat inside.Especially the central processing unit on the computer motherboard, the extreme temperatures that its running produces, and the stability requirement of telecommunication transmission is also high, therefore, all can be connected on central processing unit has small-sized fans, groups of fins, is used for keeping central processing unit to move under suitable temperature.

The modularity of central processing unit has been a kind of trend in the design of computer product in addition, and existing modularity, see also Fig. 1, for reducing cost all directly with central processing unit 20, unit load bearing seat (not shown), after the combination such as motherboard 10 devices such as grade, utilize fixture again, groups of fins 30 is engaged with motherboard 10, existing juncture generally all is to utilize intermediate plate or clamp bar combination, relevant design such as Taiwan patent application the 83217100th and No. 85210866 etc., but these designs are assembling complicated (must assemble with instrument) not only, also may touch motherboard 10 and causes short circuit (intermediate plate and groups of fins are metal); Other sees also Fig. 2, it is used in the screw juncture, and (object that is fixed is the high device of intensity between groups of fins 30 and the radiator fan 35, so the coupling mechanism force permissible range of fixture is big), as No. the 85210555th, 82206230, Taiwan patent application etc., if close the motherboard 10 that the high groups of fins of intensity 30 is low with intensity and easily break admittedly but be used in, then there is great shortcoming in the prior art of then above-mentioned two kinds of kenels.

The purpose of this utility model is to provide a kind of shatter-proof and insulation, can be with the fixture of the groups of fins of groups of fins and the convenient assembling of central processing unit module, this fixture can make the low intensive object that is fixed (as motherboard) complete and closely be fixed in high-intensity object (as groups of fins).

The purpose of this utility model is achieved by following technical proposals: it provides a kind of fixture, especially refer to a kind of fixture that is used for groups of fins is engaged in the central processing unit module, this fixture comprises: one is made of insulation or tool elastic material, to bring into play spiral shell seat shatter-proof and the insulation effect, this spiral shell seat is a hollow column, hollow column be shaped as particular geometric shapes, be used for and fixture, peg graft in the identical shaped hole of fixation, wherein the vacancy forms a conduit that connects, and offer a grooving that is communicated in above-mentioned conduit at least from the column bottom, the channel shape of spiral shell seat is a particular geometric shapes, plants in order to the cylinder that identical shaped stud is provided; This stud is metal material and can be inserted in the above-mentioned spiral shell seat conduit, and it comprises a cylinder and tail end is one to be slightly larger than the barbed body of cylinder; Wherein an end of stud can be one and is slightly larger than the column cap that cylinder can Gong be pushed, the barbed body of the other end can be a cone, the process of borrowing stud to insert the spiral shell seat struts grooving with tail end, and borrow barbed body to prop up the tail end of spiral shell seat conduit, and will be serially connected with groups of fins between the spiral shell seat, complete and closely be fixed in motherboard on the central processing unit module, make groups of fins give full play to the function of heat radiation, and assembling is easily.In addition, the cylinder of the hollow column of spiral shell seat, conduit and stud can be the cylinder bodily form.

The utility model, decapacitation are given full play to outside the heat sinking function groups of fins, more can bring into play effect shatter-proof and insulation, and can make its assembling easily, simple operation.

Fig. 6 is the three-dimensional combination figure of fixture, groups of fins and the central processing unit module of the utility model groups of fins

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings:

See also Fig. 3, it is the three-dimensional exploded view of fixture of the present utility model and groups of fins and central processing unit module 90, fixture 4 of the present utility model as shown in the figure, it is the circular hole 32 of borrowing groups of fins 30 to preset, and relative circular hole 12 on the motherboard 10 of central processing unit module, motherboard 10 and groups of fins 30 is fixing.

See also Fig. 4, fixture 4 of the present utility model comprises a spiral shell seat 40 and can be arranged in wherein a stud 50, spiral shell seat 40 is the plastic body of a hollow columnar, wherein the vacancy forms a conduit 44 that connects, column is provided with several bulge loops 42, its bottom is a cone 48, and offers a grooving 46 from the bottom and be connected to above-mentioned conduit 44.And stud 50 comprises a column cap of Gong pushing 52, is a taper barbed body 56 by extending cylinder 54, its cylinder 54 tail ends that are slightly less than column cap 52 down.

See also Fig. 3, Fig. 4, earlier spiral shell seat 40 is inserted in the circular hole 32 of groups of fins 30 during assembling, pass the circular hole 12 of motherboard again, afterwards stud 50 is inserted in the conduit 44 of spiral shell seat 40, the cylinder 54 of stud 50 struts (as shown in Figure 5) with cone 48 tail ends of spiral shell seat 40, and utilize stud 50 cone barbs 56 own to be clamped in the cone 48 of spiral shell seat 40 ends that strutted, borrow the dilatating and deformable of cone 48 devices, form interference engagement with original circular hole, and make several fixtures can groups of fins 30 is convenient and be fixed in effectively on the motherboard of central processing unit module (as Fig. 6), and unlikely destruction motherboard, thereby realize the effect of easy assembling.In addition because 40 of spiral shell seats its material has insulating properties and certain elasticity as a plastic body, can make the utility model realize purpose shockproof and insulation, its effect that can promote be have now metal intermediate plate and screw irrealizable.
