Resilient contact for connecting two parts of a device
The present invention is related to a resilient contact including a lower clamp and an upper spring arm reversely bent in opposite directions. The lower clamp can be clamped onto the upper plate of the front panel of a hard disk rack. The upper resilient arm withstands a front panel of a hard disk rack. Thus, the present invention is suitable for different size gaps to achieve the goals of electromagnetic conduction, heat conduction, support, etc.

1. Field of the Invention
The present invention relates to a resilient contact for connecting two parts of a device and more particularly, to such a resilient contact, which is applied on structural arrangement of a main server.
2. Description of Related Art
As technology progresses, computers are utilized more frequently than ever; as a result, stable operation and convenient facilitation of assembling computer hardware has been developed into an important skill nowadays, particularly in dealing with the gaps among multipler emovable hard disk racks and the gaps between racks and their associated outer case. Any potential improvement on the resilient contact thus takes into account how to achieve a stabilizing support that is at the same time able to prevent any electromagnetic waves, and efficiently dissipate heat to assure a consistent performance of the computer.
Nonetheless, conventional resilient contacts are more than often incapable of providing flexibility in adjusting the height of the spring arm or the elastic strength thereof to achieve an elastic contact at a proper level, and are constrained to the confined gap between racks or the gap between racks and the outer case. Removable hard disk racks that utilize convention resilient contacts, therefore, are rather difficult to insert into the slots or it is difficult to observe whether the spring arms of the resilient contacts have effectively made contact. Also, the width of those plate structures observed on conventional spring contacts are, most of the time, either too wide or too narrow for the size of the surface of the hard disk racks' front panels intended to be located on, causing unnecessary interference with other peripheral parts during assembling and resulting in failure to stabilize the front panel.
The present invention, on the other hand, is proposed to provide a resolution which allows easier assembly such that the plate structures of the spring contact can stably be attached onto the front panel of the hard disk rack without hindering other parts.
SUMMARY OF THE INVENTIONThe present invention has been accomplished under the circumstances in view. A resilient contact in accordance with the present invention comprises a plate structure, in which a lower clamp is mounted respectively on and extended from two front ends of the said plate structure. Each of the lower clamps is bent reversely adjacent to the plate structure to construct a small clamp opening, wherein said small clamp opening is received in between said lower clamp and said plate structure. An upper spring arm is also mounted on and extended from the central segment of the front end of the plate structure, in which the upper spring arm comprises a first bend, a reverse bow, and a second bend. The first bend is connected to the front end of the plate structure, curving upward to form a first height; the reverse bow is connected between the first bend and the second bend, shaping the second bend curving upward to form a second height, wherein the altitude of the first height is less than that of the said second height, and the tail end of the said second bend is downwardly and reversely arched.
Therefore, the resilient contact of the present invention can utilize the lower clamps and upper spring arms that are reversely bent in opposite directions to attach to removable hard disk racks in order to achieve electromagnetic conduction, heat conduction, and stabilization purposes. In addition, given that the upper spring arm of the present invention includes the first and second bend that provide different elevations, the present invention can be applied on a variety of gap sizes in between removable hard disk racks.
The plate structure of the present invention further comprises a sag piece, which can extend within the dimension of the small clamp opening thereof. The purpose of the sag piece is to insert into the corresponding slot on the upper plate of the removable hard disk device such that they are properly positioned and securely fastened. The plate structure can further comprise a cut-through slot, on the margin of which at least one of the abovementioned sag pieces is mounted, extending downward and preferably forward to construct a hook for an even more secure lock against the upper plate of the removable hard disk device.
BRIEF DESCRIPTION OF THE DRAWINGS

Referring to
Tail ends of the lower clamps 22 of the present invention are both further bent downwardly to form a small opening 221 for smoothly guiding and clamping onto the upper plate 44 of the front panel 43 of the hard disk rack 4. The plate structure 20 has sag pieces 21 that extend downwardly within the dimension of the small clamp opening 220 from the margin of a U-shaped cut-through slot 24. This embodiment in particular shapes the sag pieces to be extended forward to construct a hook such that the sag pieces can tightly insert into the corresponding slot 41 (
