Description

  The present invention relates to a kind of rotational orientation fitting. In particular, the present invention relates to a rotational orientation fitting that can be fitted with a kind of CPU and heat radiator.

In modern society, IT products such as computers are widespread, and their application range is getting wider day by day. On the other hand, the IT industry has continued to develop to increase the calculation speed of products and increase storage capacity with the aim of speeding up technological development. However, because of this, the parts of current IT products generate high heat during high-speed operation.
The amount of heat generated by the CPU accounts for most of the heat energy of the computer body, but if the amount of heat stored in the CPU exceeds its allowable limit, the computer will freeze. Moreover, in order to solve the problem of electromagnetic waves, the computer body is usually sealed in a case, but this also makes it difficult for the heat energy of the CPU and other heat generating parts (or parts) to be dissipated. It has become an important issue.
A general CPU heat dissipation method is a method in which a heat dissipator is installed approximately upward. Some fins are installed on one side of the heat dissipator, the other side of the heat dissipator (the fin is not installed) is in contact with the CPU, conducts heat energy to the end of the fin, and adds radiant heat or a fan. This quickly dissipates the heat energy.
For this reason, it is necessary to maintain a close contact state between the CPU and the heat dissipator. If there is a poor contact state, the thermal resistance easily increases and the heat dissipating effect is greatly reduced.

  As shown in FIGS. 1 and 2, the heat dissipating fitting part 1 of the CPU mainly includes a fitting bar 11. One end of the fitting bar 11 extends the vertical portion 110 in the vertical direction, and a through hole 111 is provided at the end of the vertical portion 110. The through hole 111 is fitted and fixed to a protruding block (not shown) on one side of the insertion table H on which the CPU C is loaded. An insertion tank 112 is installed at the opposite end of the fitting bar 11 and the hanging portion 12 is inserted. A hole 121 is provided in the hanging portion 12 and is movably connected to the operation component O (the eccentric hole O1 of the operation component O) by the movable shaft S. Further, the operation component O is used to rotate along the reference direction of the horizontal axis, whereby the hanging portion 12 moves toward the reference direction of the vertical axis, and the through-hole 122 provided in the hanging portion 12 is provided. Is fitted to the protruding block H1 on the opposite side of the insertion table H, and the heat radiator R is localized on the CPU C.

The known structure has the following drawbacks.
In other words, the known CPU heat sink fitting component is for fixing the heat spreader to the CPU by a fixing force that generates an eccentric hole, but the operation component has a lower dead center, so it is not easy to compress the CPU heat sink fitting component. . Insufficient fitting force due to the lower dead center may cause detachment or loosening depending on the direction in which the force is applied during dropping or shaking, and after the CPU heat dissipating fitting part is fitted, the operation part is inclined. Easy to do. In addition, there is a risk of poor contact between the heat dissipator and the CPU, which increases the thermal resistance and greatly reduces the heat dissipating effect.
The present invention provides a rotational orientation fitting that solves the problems of the above structure.

In order to solve the above-mentioned problems, the present invention provides the following rotational orientation fittings.
It mainly provides a rotational orientation fitting, can fix the CPU and heat dissipator tightly, reduce the thermal resistance, greatly improve the heat dissipating effect,
In addition, the localization component rotates and localizes along the route through which the pre-installed introduction groove passes, and the fitting force to the CPU and heat sink can be greatly improved.
Furthermore, it can operate the crossing of the fitting force direction applied to the CPU and heatsink by the direction of the force applied to the stereotactic component, and can prevent detachment and loosening due to falling or shaking.
In addition, it utilizes the coupling of the elastic part to the stereotactic part, which does not swing due to external forces,
That is, it mainly includes the support frame body, stereotactic parts,
The support frame body is fitted to the localization component, and an engagement lock portion is installed. The localization component includes an adjustment unit and a fitting unit, and the engagement lock portion is also installed in the fitting unit of the localization component. ,
Using the engagement lock part of the support frame main body and the engagement lock part of the localization component, the object is fitted and fixed, and the adjustment unit is rotated along the X-axis direction with the Y-axis as a reference reference point. Thus, the adjustment unit performs a reciprocating movement in the Y-axis direction, and thus the engagement lock portion of the localization component is a rotational localization fitting tool characterized in that the object to be fitted is tightly fixed or loosened.

  As described above, the present invention provides a rotational positioning fitting and lowers the thermal resistance by tightly fixing the CPU and the heat dissipator, and the positioning component of the present invention follows a route through which a pre-installed introduction groove passes. Therefore, the fitting force with respect to the CPU and the heat dissipator can be greatly improved. Furthermore, the direction of the force applied to the localization component can be operated by crossing the direction of the mating force applied to the CPU and the heatsink to prevent detachment or loosening due to dropping or vibration, and the localization of the localization component can be achieved using the coupling of the elastic component to the localization component. It is possible to eliminate the fear that the component will swing due to external force.

As shown in FIGS. 3, 4, 5, and 6, the rotational positioning fitting 2 of the present invention mainly includes a support frame main body 21 and a positioning component 22.
The support frame main body 21 is fitted into the localization component 22. An engagement lock portion 210 is installed on the support frame main body 21, thereby fitting a projection block 41 (not shown) installed at one end of the insertion table 4 on which the CPU 3 is loaded. The support frame main body 21 is horizontally in close contact with one side of the heat dissipator 5 of the CPU 3 and extends toward the opposite side of the heat dissipator 5 so that the heat dissipator 5 is in close contact with the CPU 3. Thus, the heat energy generated when the CPU 3 operates can be derived by the heat dissipator 5.
The localization component 22 is fitted on the opposite side of the support frame main body 21 (relative to the engagement lock portion 210). An engagement lock portion 2221 is installed on the localization component 22, and is fitted to the protruding block 41 on the opposite end of the engagement lock portion 210 by the insertion base 4, and the localization component 22 is rotated. The engagement lock portion 2221 is driven to bring the heat spreader 5 and the CPU 3 into close contact. In this way, the thermal resistance between the heat dissipator 5 and the CPU 3 is greatly reduced, and the heat dissipating effect is improved. Furthermore, the direction in which the localization component 22 is applied intersects with the direction of the fitting force applied to the CPU 3 and the heat dissipator 5, thereby enhancing the fitting action on the object (CPU 3, the insertion table 4, the heat dissipator 5, etc.). can do. That is, by adjusting the localization component 22, the engagement lock portion 2221 tightly couples the objects to each other (contact, bonding, close contact, etc.), and prevents the object from falling or coming loose due to vibration. be able to.

In the optimum embodiment, the localization component 22 is constituted by the adjustment unit 221 and the fitting unit 222 (the adjustment unit 221 and the fitting unit 222 may be integrally formed). The adjustment unit 221 is provided with an introduction groove 2210, the flange 2211 is extended outward, and the user rotates it.
The support frame body 21 also has a rod-like structure (see the figure), and is provided with at least one opening 211 (installed at the opposite end of the engagement lock portion 210 that extends in the Y-axis reference direction of the support frame body 21). Possible). Thus, the fitting unit 222 is fitted into the opening 211 to join the adjusting unit 221 (or the support frame main body 21 is fitted into the localization component 22 with the opening 211).

Further, the support frame body 21 extends at least one support arm 212 around the opening 211. The support arm 212 is provided with at least one hole 2120 and is fitted with the main shaft 23. The main shaft 23 passes through the introduction groove 2210 and engages with the adjustment unit 221. When the adjustment unit 221 is turned, the adjustment unit 221 corresponds to the route of the main shaft 23 by the introduction groove 2210, and the localization An application force is formed on the component 22, and the engagement lock portion 2221 installed by the fitting unit 222 is interlocked. In this way, the object is closely fitted or loosened, and the direction of the applied force intersects the direction of the fitting force applied to the object by the localization component 22. Further, the user turns the adjustment unit 221 in the clockwise or counterclockwise direction about the Y axis with the Y axis as a reference reference point. Thus, the adjustment unit 221 reciprocates in the Y-axis direction along the route through which the main shaft 23 and the introduction groove 2210 pass. As a result, the engagement lock portion 2221 of the fitting unit 222 is interlocked, and one end of the insertion table 4 on which the CPU 3 is loaded is tightly pressed or loosened, so that a plurality of objects (the CPU 3, the insertion table 4, the heat radiator) 5 etc.) are in close contact with each other (or closely, fitted) or separated. Further, since the introduction groove 2210 has a bent shape, when the adjustment unit 221 is rotated to the end of the introduction groove 2210 (the end can be recessed), a localization action is generated. Thus, the engagement lock portion 2221 of the projection block 41 of the insertion table 4 and the engagement lock portion 220 of the fitting unit 222 are fitted and fixed, and thus the insertion table 4, the CPU 3, and the heat dissipator. 5 or the like (so-called object) can be brought into close contact with each other, so that occurrence of detachment or loosening can be prevented even by dropping or shaking.

The elastic body 24 (bow shape, C shape, U shape, or other shape) is installed between 21. The elastic bodies 24 push up the fitting unit 222 and the support frame main body 21, respectively, improve the stability of the fitting unit 222, and prevent the fitting unit 222 from shaking due to vibration. Moreover, the orientation of the fitting unit 222 with respect to the protruding block 41 of the insertion table 4 can be enhanced.

Subsequently, as shown in FIGS. 9 and 10, in the third embodiment of the rotational positioning fitting 2 of the present invention, the elastic body 24 extends the holding portion 240, holds the fitting unit 222, and the elastic body. The coupling force between the fitting unit 24 and the fitting unit 222 can be improved.
Further, as shown in FIGS. 11 and 12, in the fourth embodiment of the rotational positioning fitting 2 of the present invention, since the support arm 212 forms at least one flange 2121, the support arm 212 has the hole 2120. It is not necessary to fit the main shaft 23. That is, by utilizing an alternative action of the flange 2121 to the main shaft 23, the flange 2121 rotates corresponding to the route through which the introduction groove 2210 passes, and moves the adjustment unit 221 to exert the action of localizing the object. be able to.

Next, as shown in FIGS. 13 and 14, in the fifth embodiment of the rotational positioning fitting 2 of the present invention, the support arm 212 forms at least one flange 2121. There is no need to fit the main shaft 23. That is, by utilizing an alternative action of the flange 2121 to the main shaft 23, the flange 2121 rotates corresponding to the route through which the introduction groove 2210 passes, and moves the adjustment unit 221 to exert the action of localizing the object. be able to.
Further, as shown in FIGS. 13 and 14, in the sixth embodiment of the rotational positioning fitting 2 of the present invention, the support arm 212 forms at least one flange 2121. 23 need not be fitted. That is, the flange 2121 is rotated corresponding to the route through which the introduction groove 2210 (the flange 2121 is joined to the introduction groove 2210 of the adjustment unit 221) by utilizing the alternative action of the flange 2121 with the main shaft 23. The adjustment unit 221 can be moved to exert an effect of localizing the object.

In each of the above-described embodiments, the protrusion rod 2220 (see FIG. 17) can be formed on one side of the fitting unit 222 to increase the stress of the fitting component 222.
Further, the introduction groove 2210 (see FIG. 18) forms a plurality of continuous bent structures, and the ends of the introduction groove 22 are depressed, and a localization action is generated with respect to the adjustment unit 221. Thereby, objects such as the insertion table 4, the CPU 3, and the heat dissipator 5 can be tightly coupled to each other.
