Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an interface card securing device, and more particularly to an interface card securing device including a grounding element for reducing interference during high speed signal transmission of the interface card.

2. Description of Related Art

The advancement of technology paved way for the electronic product to be more comprehensive in order to meet market demand. The present trend of the electronic product to be thin and small occupying lesser space and high portability are common demand of users. Accordingly, the manufacturers develop the electronic products to be as compact and small as possible.

Thus, the specification and structure of the components of the computer and electronic devices are being altered and redesigned accordingly so as to provide higher operation efficiency, easy to assemble, and also smaller in size.

The securing device used for securing the interface card available on the market are available in various structures equipped with several securing schemes. As the size of the components is being reduced continuously for meeting the current trend, the structural strength of the securing device is consequently reduced and the small size of the securing device is difficult to handle.

For overcoming the above defects, the inventor of the present invention proposes an interface card securing device, which is fabricated by using a plastic injection process. Thus, the fabrication of the interface card securing device may be substantially simplified and the fabrication cost can be effectively reduced, and is suitable for mass production. Furthermore, the structural strength of the interface card securing device is adequate, and is easy to handle and assemble. According to an embodiment of the present invention, the interface card securing device comprises a grounding element for reducing interference during high speed signal transmission of the interface card.

SUMMARY OF THE INVENTION

Accordingly, the present invention provides interface card securing device comprising a grounding element. The grounding element may reduce the interference during high speed signal transmission of the interface card. Thus, the signal transmission quality may be effectively promoted. The grounding element may be integrally-formed with the interface card securing device as a single unit. Thus, the interface card securing device of the present invention is simple and easy to assemble. Furthermore, the interface card securing device may be fabricated using the mature conventional plastic injection molding process, and therefore the fabrication process of the interface card securing device is simple and the fabrication cost thereof may be effectively reduced.

DETAIL DESCRIPTION OF THE INVENTION

FIG. 1 shows is a perspective view of a housing of the securing device according to the embodiment of the present invention. Referring to FIG. 1, the housing 100 may be formed using a conventional plastic injection molding process. The housing 100 comprises a securing set 1, a connecting portion 2 and a string connecting stopper 3. The securing set 1 comprises sleeve 11 that protrude upward and a joint portion 12. The joint portion 12 comprises a plurality of indentations 12a at a flange of the securing set 12. A securing portion 13 with a hook may be disposed beneath the securing set 1. The securing portion 13 comprises a terminal slot 60 formed at a central portion thereof. The terminal slot 60 comprises a securing slot 60a, a movable slot 60b formed on two sides thereof and a horizontal slot 60c. The moveable slot 60b may be comprised of an opening extending from the sleeve 11 to the joint portion 12. Referring to FIGS. 2 and 3, the stopper 3 comprises a slot 31 surrounded by a plurality of protrusions 31a, and a slot 32 is formed adjacent to the slot 31.

FIG. 4 a perspective view of a grounding terminal of the grounding element for an interface card securing device according to the embodiment of the present invention. Referring to FIG. 4, the grounding terminal 70 comprises a fixing element 7 including a hook, a moveable arm 7a having a protrusion 70a formed on a front side thereof and a welding terminal 7b formed on another side thereof.

FIG. 5 is a perspective view of a grounding plate of the grounding element for an interface card securing device according to an embodiment of the present invention. Referring to FIG. 5, the grounding plate 80 is comprised of a plate having protruded hooks formed on two sides thereof, wherein the bottom portion of the grounding plate 80 (as shown in FIG. 5A) may be bent into a contacting portion 80a to increase the contact surface.

FIGS. 6 and 7 are exploded views of a grounding element for an interface card securing device according to an embodiment of the present invention. Referring to FIGS. 6 and 7, the securing device 1000 adapts the grounding terminal 70 using the terminal slot 60 of the securing set 1 (as shown in FIGS. 8 and 9).
