Technical field
The utility model relates to a kind of fastener and uses the heat abstractor of this fastener, particularly a kind of fastener that uses and heat abstractor that uses this fastener of matching with the heater element of electronic installation.
Background technology
Along with the development of electronic industry technology, the transistor density of all kinds of chips (particularly central processing unit) increases day by day, and the speed of deal with data is more and more faster.As everyone knows, electronic component all can produce heat when work, and the central processing unit of computer is no exception.The increase of central processing unit arithmetic speed, the power of its consumption and the heat of generation also increase thereupon, so we must attach the temperature that the heat abstractor that is used to dispel the heat reduces central processing unit on central processing unit, keep its normal steady operation.
Generally speaking, the heat abstractor of central processing unit adds above central processing unit haply puts a radiating block, and some fin are set above radiating block, so that the mode by radiating block bottom contact central processing unit conducts out with heat, after heat conducts to the fin end, by radiation or cooperate the radiator fan on it that heat is extracted out.Therefore, between radiating block and the central processing unit, must keep contact condition closely constantly, so that the more efficiently conduction of heat.Usually by fastener radiator and central processing unit base are fastened, realize keeping central processing unit and the tight of radiating block to contact.
The fastener of known central processing unit thermic devices mainly contains two kinds: a kind of is sealed by Spring screws, at heat abstractor four pin Spring screws is set it is anchored on the central processing unit base, its principle is to fix by screw thread, in screw locking assembling, Spring screws is compressed a length and produces the necessary thrust that keeps heat abstractor and central processing unit; Another kind is to adopt elastic force jig snap-in structure, the many employings of elastic force jig have certain flexible sheet metal and are stamped to form, and jig separates with heat abstractor when assembling, during assembling, the trip of jig and central processing unit base button hole fasten, elasticity arm pressurized on the jig rotates an angle simultaneously, produces the necessary thrust of heat abstractor to central processing unit.Because these two kinds of method complex structures not only expend time in during assembling, and, make computer after moving, shaking, the phenomenon that heat abstractor and central processing unit are separated usually takes place usually because the fastening dynamics is not enough.
Summary of the invention
The utility model provide a kind of simple in structure, easy to assembly, fasten firm fastener.
Another purpose of the utility model is to provide a kind of heat abstractor simple in structure, easy to assembly.
Implement fastener of the present utility model and comprise supporting substrate, some elasticity arms and button hook, this button hook is arranged on the elasticity arm, and wherein elasticity arm is positioned at the edge of supporting substrate, and with supporting substrate be integrated integral body.
Implement heat abstractor of the present utility model and comprise fastener and radiator, wherein said fastener is made up of supporting substrate, elasticity arm and button hook, this button hook is arranged on the elasticity arm, and wherein elasticity arm is positioned at the edge of supporting substrate, and with supporting substrate be integrated integral body.
Owing to adopted technique scheme, the utility model compared with prior art has the following advantages: because supporting substrate of the present utility model and elasticity arm are integrated integral body, so simple in structure, the mould development expense is low, reduces production costs when helping making; Simultaneously, because fastener overall structure of the present utility model is simple, so the integral heat dissipation means number of elements is less, and the assembling of heat abstractor is simple and convenient and be beneficial to the reduction manufacturing cost.
