Abstract

The fastener has a movable side piece (20) with a hook (21) at its end, where the hook is hooked to a central processing unit by rotation of a lever (10) in a hole (71) of a fastening frame (70). The side piece (20) is guided through an opening of a bow-shaped or U-shaped or C-shaped spring unit (30). The spring unit has a vertical clamping part on one end. A clamp (90) is provided in the fastener.

Description

technical area

The The invention relates to a mounting for heat sinks, which avoid a fluctuation can and has easy handling.

State of technology

The operating heat the central unit must be removed, about damage to avoid the central unit by this waste heat.

To the Cool the central unit is usually uses a heat sink, of a variety of cooling fins which has the operating heat the central unit can absorb. Therefore, the heat sink must be tight on the central unit rest.

Out TW 560646 a fixture for heat sink is known, which has a complicated structure and requires a tool.

Out TW 560646 Another attachment for heat sink is known which has two legs, which has a hook at the end. During use, the hook of a leg first hooks into a hole in a mounting frame. Subsequently, the hook of the other leg can hook by turning a lever in another hole of the mounting frame. The latter, however, is difficult.

Task of invention

Of the Invention is based on the object, a fastening for heat sink which can avoid a fluctuation and easy handling having.

These Task is solved by the inventive attachment for heat sink, the from a lever, a movable leg, a spring element and a hanger exists, with the hanger on one side has a leg which has a hook at the end has, and wherein the movable leg has a hook at the end, by turning the lever into a hole of a mounting frame can hook around the central unit, characterized in that the movable leg is guided by the spring element, by which the stability of the movable Thighs increased is, so that a fluctuation of the movable leg avoided becomes.

Ways to execute the invention

Further Details, features and advantages of the invention will become apparent the following detailed description in conjunction with the adjacent drawings.

The 1 and 2 show a preferred embodiment of the invention, which consists of a lever 10 , a movable thigh 20 , a spring element 30 and a hanger 90 consists. The lever 10 ( 3 ) has a main body 11 with a rib on one side 111 forms, through which the strength of the lever 10 is increased. The main body 11 Also has at one end an actuating part 12 provided with strips (not shown) to prevent slipping and at the other end a projection 13 that with a slot 131 in which the movable thigh is provided 20 is plugged. The lead 13 has an eccentric hole 132 and the movable thigh 20 has an axle hole 22 , A bolt 80 is through the eccentric hole 132 of the projection 13 and the axle hole 22 of the movable leg 20 guided. When the lever 10 is rotated, the movable leg can be moved in the Y direction.

The coat hanger 90 ( 1 ) has an opening 91 on, through which the movable thigh 20 which is then passed over the bolt 80 with the lever 10 articulated is connected.

In the present embodiment, the movable leg has 20 at the end a hook 21 that in a hole 71 a mounting frame 70 about the centrality 60 can hook. The coat hanger 90 makes another thigh 92 which at the end has a hook in another hole 71 ' can hook. This allows the heat sink 50 on the central unit 60 be attached. When the lever 10 is turned, the hook can 21 at the end of the mobile leg 20 in the hole 70 of the mounting frame 70 hook. This allows the heat sink 50 close to the central unit 60 be held, reducing the thermal resistance between the heat sink 50 and the central unit 60 is reduced, so that the cooling effect is increased.

The essential feature of the invention is that the movable leg 20 by the spring element 30 is guided. The spring element 30 can be ironed, U- or C-shaped, as it is in 1 is shown, and has at least one opening 31 through which the moving Schenekl 20 is guided. By the spring element 30 can the stability of the mobile leg 20 be increased, leaving a fluctuation of the movable leg 20 is avoided. One end of the spring element 30 can be a vertical clamping part 32 form, causing the movable leg 20 from the spring element 30 can be clamped. The other end of the spring element 30 makes a stop 33 that is attached to the heat sink 50 can be present. Therefore, a release of the movable leg 20 be prevented by an external force.

by virtue of the above facts, the invention corresponds in its availability, Progressiveness and novelty fully on the requirements for a utility model.

The The above description represents only a preferred embodiment of the invention and should not be used as a definition of boundaries and serve the scope of the invention. All equivalent changes and modifications are included to the scope of this invention.
