Abstract

A radiating-fin buckling-component structure, the buckling-component structure combines and fixes the radiating-fin and the commutator and the bottom attaching surface of the radiating-fin clings to the surface of the commutator wafer. The buckling-component is n-shaped, which has a screw hole in the centre of the horizontal base. Each screw hole is screwed with a screw and a cantilever is arranged adown on each side of the buckling-component, provided with a buckling part which has a buckling hole of the buckling-component in the end of the cantilever and the buckling holes of the buckling-component combined with a buckling hook of the commutator, so when the screw is circumrotating on the top of radiating-fin, the buckling holes will lock or release at the hooks of the commutator so as to make the assembling or disassembling easily conducted and the device difficult to break off.

Description

The Radiator fin clamp structure

Technical field:

The utility model relates to a kind of heat radiator, relate in particular to a kind of fastener structures of heat radiator, utilize one to be Π shape bending fastener, establish the shrinkage pool that screw and heat sink top surface are offered thoroughly in horizontal base central authorities, when screw rotates, make the fastener button hole be engaging or loosen button hook place, to reach loading and unloading easily at breakout box, fix tightly, and the effect of difficult drop-off.

Background technology:

Computer widespread each stratum in society now, and the central processing unit grafting fixed form in traditional computer, directly be welded on the central processing unit pin on the circuit board mostly, but because of central processing unit after damage more change poles be not easy, and when instrument (as flatiron, welding gun etc.) is heated in use, make central processing unit itself bear high temperature, cause central processing unit very easily to burn out.Relevant manufacturer makes central processing unit use on circuit board for activity orientation with regard to designing a kind of breakout box for switching usefulness, but in application, because of central processing unit hole pin slightly inclined just, cause the bending of pin or break, so the producer that has just considers how to make central processing unit is simple and easy to be positioned on the breakout box, and then design a kind of pin of central processing unit, on breakout box, have low insertion force, the characteristic of high withdrawal force during plug.

In addition, existing more powerful because of computer function, arithmetic speed promotes rapidly, and the temperature that makes central processing unit be produced when handling operational order is higher.So the sort of low insertion force, how the breakout box of high withdrawal force combines with heat radiator, in order to central processing unit under the temperature of its permission operate as normal as important topic, the producer that has is combined on the two side grabs that heat radiator and breakout box connect with a screw, and present central processing unit buckling device of radiator, as shown in Figure 6, it is the outside three-dimensional structure diagram of using always, it mainly utilizes the lamellar body central authorities of a bending to be the subsides portion that supports of bending down, can insert in the heat radiator and push against bottom at heat radiator, it is two grabs that fasten breakout box with the button hole that is articulated in the rotatable lamella on other the side engagement end that the button of one side is held end, and the circular arc support division that makes rotatable lamella and button hold the downward formation of end pushes against the side at pedestal.The base button hole is to connect to be buckled in breakout box front and back end symmetry and to give on the grab of establishing, this designs buckling device as two formulas, for reaching button firm when holding, adaptation in the time of must improving combination, relative size also must be accurately, but when carrying because of general computer, have and rock the collision situation generation, and heat radiator has constant weight, so heat radiator very easily forms lateral shift on breakout box, and the rotatable lamella that can make device for fastening one side produces state loosening or that break away from, thus how to make in conjunction with after integral body have concurrently stable do not rock and easily loading and unloading are the problems that must study.

Summary of the invention:

This is practical to be to utilize one to be shape bending fastener and to offer shrinkage pool in screw and heat sink top surface that base portion central authorities establish thoroughly, screw togather with screw, fastener is moved up by the button hole of the threaded portion of screw be fastened in the clasp of breakout box, to reach loading and unloading easily, the fix tightly and the effect that should not come off.And utilize and one-body molded whole cost is significantly reduced, and can gain in strength and retain strength.Structure of the present utility model is heat radiator to be combined fixing with breakout box with a fastener, and the contact Π face that makes heat radiator bottom supports and is attached on the wafer surface of tool breakout box, fastener generally is a Π type body, the central authorities of its horizontal base are provided with a screw thoroughly, locked screw in its screw, each has extended a cantilever down by two sides in addition, and the buckling parts of a button hole arranged in cantilevered distal end, the button hole of fastener is linked on the clasp of breakout box, screw rotates at the heat radiation end face, and the fastener button hole is engaging or loosens clasp place at breakout box.Heat sink top surface can be provided with shrinkage pool, can be a location state when screw rotates, and screw can be a manual bolt.

By on know, when screw is screwed togather, fastener moves up by the threaded portion drive fastener of screw, and then make the buckling parts button hole be fastened in the clasp of breakout box and present one to push against state, when in addition screw being loosened, can make fastener break away from breakout box easily, reach loading and unloading easily, fix really and the effect of difficult drop-off with this.
