The follower parts 131b are actuated downward gradually along with the heat dissipating component 14 moving downward continuously such that the secure part 131a of each engaging member 131 are actuated to move inward gradually till catching upper edges 142 of the cooling fins as shown in FIGS. 12. In this way, the heat dissipating component 14 can be tightly attached to the CPU 16 on the support member 15.
As the foregoing, the first locating set 22 and the second locating set 13 are mounted to the lateral sides of the base body by means of fixed joining and the engaging members are provided elastically for being able to expand and secure the heat dissipating component to the base body.
It is appreciated that comparing to the prior art, the secure device of the present invention has the following advantages:
The secure device of the present invention applies lever principle, that is, the respective pivot unit acts as the fulcrum and the follower part and the secure part of each engaging member are disposed at both ends of the pivotal unit. The secure parts approach the heat dissipating component gradually till the heat dissipating component has touched the base body completely when the heat dissipating component moves toward the base body gradually. Once the heat dissipating component has touched the base body completely, the engaging members are capable of clamping the heat dissipating component tightly. It only needs one movement for performing the job of the heat dissipating component being mounted to the base body.
The secure device of the present invention applies multiple forces exerting to the base body such that the base body is subjected to forces evenly such that the secure device is hard to become fracture and the effect of clamping can be maintained even if one or two spots in the secure device are fractured.
Due to multiple-force clamping being used, the clamping forces are evenly distributed such that the heat dissipating component is capable of tightly attached to the heat generation component such as CPU flatly via the base body for heat being able to transmit outward rapidly.
The secure device of the present invention is fabricated with less material and labor costs and is much simpler for being set up with much better effect in use than the prior art.
Number of the engaging members in the secure device of the present invention can be added or reduced flexibly to comply with heat dissipating component in different shapes such as circular or rectangular shapes.
The first locating sets and the second locating sets in the secure device of the present invention can be provided to meet different necessities such as all of them being pivotal, only one of them being pivotal or all of them being fixed.
While the invention has been described with referencing to preferred embodiments thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of this invention, which is defined by the appended claims.
