The first side 101 a of the interface card 101 is inserted into the motherboard slot 103 a of the motherboard 103. The fastening part 101 c is disposed on the second side 101 b of the interface card 101 and is exposed outside the opening 105 a. When the first side 101 a of the interface card 101 is inserted into the motherboard slot 103 a, the fastening part 101 c of the interface card 101 is against the locking portion 141 of the casing 105. And at least one positioning box 109 is fixed on the casing 105 and adjacent to the opening 105 a of the casing 105.
Reference is made to FIG. 2A, which depicts a perspective view showing the positioning box 109 of the fastening device and the interface card 101 in accordance with the first preferred embodiment of the present invention. The positioning box 109 is disposed on the casing 105. The positioning box 109 includes a leading slot 110, a box opening 131 (as shown in FIG. 2C) and a positioning slot 121. The securing member 111 is movably disposed within the positioning box 109. As shown in FIG. 2B, the securing member 111 includes a pushing part 112 and a securing part 113, which connect with each other. The cross-sectional of the securing member 111 is preferred a ring shape. The material of the securing member 111 is preferred to be plastics, and the material of the positioning box 109 is preferred to be metal.
Reference is made to both FIGS. 2A and 2B, wherein the FIG. 2B depicts a perspective view showing the securing member 111 of the fastening device in accordance with the first preferred embodiment of the present invention. The securing member 111 further includes a pushing shaft 117 and a deformable space 123. The pushing shaft 117 protrudes from a surface of the securing member 111 and exposes outside the leading slot 110 of the positioning box 109. The pushing shaft 117 is used to provide a place for applying a force by a user. The pushing part 112 of the securing member 111 includes a flexible arm 112 a, which could be bent upward or downward in the deformable space 123 with flexibility. When user pushes the pushing shaft 117 along an A1 direction, the flexible arm 112 a bends downward, as shown in FIG. 2B.
Referring to FIG. 2B, the securing member 111 further includes a protrusion 115. The protrusion 115 is disposed on the flexible arm 112 a. The protrusion 115 is selectively lodged in the positioning slot 121. When the flexible arm 112 a bends downward, the protrusion 115 could be released from the positioning slot 121. When the pushing part 112 pushes the securing part 113 to pass through the positioning box 109 and expose outside the box opening 131 (as shown in FIG. 2C), the fastening part 101 c of the interface card 101 is against the locking portion 141 of the casing 105, and the first side 101 a of the interface card 101 is against the motherboard slot 103 a of the motherboard 103. At the same time, the protrusion 115 of the securing member 111 is lodged in the positioning slot 121. When the protrusion 115 is separated from the positioning slot 121, the interface card 101 could be drawn from the motherboard slot 103 a of the motherboard 103.
Furthermore, reference is made to both FIGS. 2C and 2D, wherein FIG. 2C depicts a perspective view showing the backside of the securing member 111 and the positioning box 109 at a beginning position in accordance with the first preferred embodiment of the present invention, and FIG. 2D depicts a perspective view showing the backside of the securing member 111 and the positioning box 109 at a locking position in accordance with the first preferred embodiment of the present invention. Before the user installs the interface card 101, the securing member 111 is disposed in the positioning box 109. That is, the pushing part 112 and the securing part 113 of the securing member 111 are both disposed in the positioning box 109. The securing member 111 is at the beginning position. When the user pushes the pushing shaft 117 along a B1 direction, the securing part 113 passes through the positioning box 109 and exposes outside the box opening 131, while the pushing part 112 does not. Because the cross-section area of the securing part 113 is smaller than the cross-section area of the box opening 131, and the cross-section area of the pushing part 112 is larger than both the cross-section areas of the securing part 113 and the box opening 131. The securing part 113 exposed outside the box opening 131 leans against the second side 101 b of the interface card 101 tightly, so that the interface card 101 is fixed on the motherboard 103 and the casing 105 reliably. At the same time, the pushing part 112 is leaned against the fastening part 101 c of the interface card 101, and the protrusion 115 of the securing member 111 is lodged in the positioning slot 121 of the positioning box 109. The securing member 111 is at the locking position.
Referring further to FIGS. 2C and 2D, there is a flexible component, such as a spring 133, disposed between the positioning box 109 and the securing member 111. When the pushing part 112 moves along the B1 direction, the spring 133 is compressed, so that a potential energy is saved therein. When the user wants to disassemble the interface card 101, the user could push the protrusion 115 or the pushing shaft 117 of the securing member 111 downward. The protrusion 115 moves downward and is released from the positioning slot 121 of the positioning box 109, since the flexible arm 112 a is having flexibility. The spring 133 provides a resilient force to the securing member 111, so that the securing part 113 moves back into the positioning box 109, and the securing member 111 moves back to the beginning position.
Reference is made to FIGS. 3A, 3B and 3C. FIG. 3A depicts a perspective view showing a securing member 211 in accordance with the second preferred embodiment of the present invention. FIG. 3B depicts a perspective view showing a positioning box 209 and a securing member 211 in accordance with the second preferred embodiment of the present invention. FIG. 3C depicts a perspective view showing a positioning box 209 and a securing member 211 at a locking position in accordance with the second preferred embodiment of the present invention. Unlike the first preferred embodiment of the present invention, a positioning slot 221 and a leading slot 210 of the second preferred embodiment of the present invention are connected. That is, the positioning slot 221 and the leading slot 210 could be integrally formed, as shown in FIG. 3B. As shown in FIG. 3A, the securing member 211 comprises a pushing shaft 217, a pushing part 212, and a securing part 213. The pushing shaft 217 is disposed on one end of the pushing part 212, and the pushing shaft 217 is selectively lodged in the positioning slot 221. Preferably, the positioning slot 221 is disposed on one end of the leading slot 210. The user could push the pushing shaft 217 along a C1 direction, such as from a front end of the leading slot 210 to the back end of the leading slot 210. For example, when the pushing shaft 217 is pushed to the back end of the leading slot 210, the user could push the pushing shaft 217 to rotate along a D1 direction, and the pushing shaft 217 is lodged in the positioning slot 221. When the user want to disassemble the interface card, the user could push the pushing shaft 217 to rotate along a direction reverse to the D1 direction, and the pushing shaft 217 of the securing member 211 is separated from the positioning slot 221 of the positioning box 209. A spring disposed between the securing member 211 and the positioning box 209 provides a resilient force to move the securing member 211 back to a beginning position. Preferably, the leading slot 210 combines the positioning slot 221 together to form a “J” shape. However, the shape that the leading slot 210 and the positioning slot 221 combine is not limited to the “J” shape; any shape for performing the same function of lodging the securing member 211 could be used.
Therefore, according to the aforementioned preferred embodiments, the advantage of the fixing apparatus of the present invention is that a user could install and disassemble the interface card without any tool: Instead, the user could install and disassemble the interface card manually by a securing member of the present invention. Comparing with the prior method of using screws and screwdriver, the present invention is very convenient and saves lots of time.
