Description

Fixing frame assembly

The present invention relates to a mount assembly, and more particularly to a mount assembly having a slidable stop.

In order to meet the needs of electronic devices (such as desktop computers, notebook computers or servers), users usually improve the performance of electronic devices by plugging expansion cards into the expansion slots of the electronic devices. . The expansion card is, for example, a display card, a network card, a sound card or a memory card.

Generally, the expansion card is mostly disposed on the board of the electronic device through the carrier, and the carrier is also matched with the rotating fastener to limit the expansion card to the rotating fastener. However, since the opening and closing of the rotating fastener is through the rotating manner, when the electronic device is subjected to vibration or impact, the rotating fastener is easily rotated relative to the carrier, and is disengaged from the position of the original limiting expansion card, so that the expansion card is Without the limit of the rotating fastener, the expansion card may be separated from the expansion slot by vibration or impact.

SUMMARY OF THE INVENTION The present invention is directed to a holder assembly that solves the problem of the prior art rotary opening and closing rotary fastener being easily disengaged from the expansion card when the electronic device is subjected to vibration or impact.

The limiting member is slidably mounted on the fixing frame body, and the limiting member is slidable between a limiting position and a releasing position. The sliding direction of the limiting member is not parallel to the assembly direction of the assembly frame. When the limiting member is in the limiting position, the limiting member stops on one side of the bearing frame and is used to abut against the assembly frame. When the limiting member is in the release position, the limiting member is used to be disengaged from the assembly frame.

According to the fixing frame assembly disclosed in the above embodiment, since the sliding direction of the limiting member is not parallel to the assembly direction of the assembly frame of the expansion card, when the fixing frame assembly is shaken or impacted, the limiting member at the limiting position is not It is easy to slide to the release position with shaking or impact.

Next, please refer to Figure 2, Figure 5 and Figure 6. Figure 5 is a cross-sectional view of Figure 1. Figure 6 is a top plan view of Figure 1.

The opposite ends of the limiting member 400 are slidably disposed on the first guiding portion 123 and the second guiding portion 115 respectively, and the sliding direction D2 of the limiting member 400 is, for example, orthogonal to the assembly direction D1 of the expansion card 20. In detail, the limiting member 400 includes a connected body portion 410 and a spring piece portion 420. One end of the frame portion 410 is slidably disposed on the first guiding portion 123 , and the other end of the frame portion 410 and the elastic piece portion 420 are slidably disposed on the second guiding portion 115 . The body portion 410 has a side surface 411 , a guiding surface 412 , a first guiding groove 413 , a first positioning structure 414 , a second positioning structure 415 , a plurality of stopping surfaces 416 , and a plurality of protrusions 417 . The side surface 411 is connected to the guide slope 412 and faces the first guiding portion 123, and the first guiding groove 413 is recessed from the side surface 411. The first positioning structure 414 and the second positioning structure 415 are, for example, flanges. The first positioning structure 414 and the second positioning structure 415 are respectively located on opposite sides of the first guiding slot 413, and the first positioning structure 414 and the second positioning structure 415 are respectively opposite to the side walls of the first guiding slot 413. A limit space 418, 419 is formed. The guiding post 500 is disposed through the first guiding portion 123 , and a portion of the guiding post 500 is located at the first guiding slot 413 . These stop faces 416 face the stop structures 1122, respectively, and the bumps 417 protrude from the stop faces 416, respectively. The elastic piece portion 420 has a guiding protrusion 421, the second guiding portion 115 further has a second guiding groove 1151, and the guiding protrusion 421 is slidably located at the second guiding groove 1151.

In the process of assembling the limiting member 400 to the first guiding portion 123 and the second guiding portion 115, the guiding inclined surface 412 can be abutted against the first guiding portion 123, and then transmitted through the elasticity of the elastic piece portion 420. The limiting member 400 is assembled between the first guiding portion 123 and the second guiding portion 115. Therefore, the arrangement of the guide slope 412 and the elastic piece portion 420 contributes to the improvement of the assembly convenience of the stopper 400. However, the arrangement of the guide bevel 412 and the shrapnel portion 420 is not intended to limit the invention. In other embodiments, the side of the frame portion facing the first guiding portion may be only one plane, and the limiting member may be free of the elastic piece.

In this embodiment, the limiting member 400 is slidable between a limiting position and a releasing position. Hereinafter, the relationship between the components when the stopper 400 is in the limit position will be described first.

As shown in FIG. 5 and FIG. 6 , when the limiting member 400 is in the limiting position, the guiding post 500 is limited to the limiting space 418 by the first positioning structure 414 , and the stopping surfaces 416 of the frame portion 410 . The stop structures 1122 are respectively abutted, and the bumps 417 respectively pass through the through holes 1122a of the stop structures 1122. At this time, the limiting member 400 stops at the side of the second bearing portion 112 (shown in FIG. 2 ) away from the second covering portion 122 (shown in FIG. 2 ), and the limiting member 400 abuts against the assembly frame. The second portion of 21 abuts the plate 23 and shields portions of the second abutment plate 23 of the assembly frame 21.

In order to clearly describe the relationship in which the expansion cards 20 are constrained in the storage space 600, the X-axis, Z-axis, and Y-axis directions orthogonal to each other are first defined. The X-axis direction is a direction parallel to the normal line of the second covering portion 122, and the Z-axis direction is a direction parallel to the normal line of the first covering portion 121.

As shown in FIG. 2 and FIG. 5 , the second abutting plate 23 of the assembly frame 21 is limited between the limiting member 400 and the second bearing portion 112 when the limiting member 400 is in the limiting position. Therefore, the movement of the expansion cards 20 in the positive X-axis direction is restricted, so that the expansion cards 20 can be prevented from being separated from the storage space 600 from the positive X-axis direction and separated from the slots 31 of the circuit boards 30.

Furthermore, as shown in FIG. 2 and FIG. 3, the bearing strips 1111, the third bearing portion 113 of the first bearing portion 111 and the assembly holes 1221 restrict the first abutting plates 22 of the expansion cards 20 from being positive. Y axial movement, and these support lugs 1121 limit the movement of the second abutment plates 23 of the expansion cards 20 in the positive Y-axis, and the abutment pieces 1222 respectively limit the first abutment plates of the expansion cards 20 22 moves in the negative Y axis.

In addition, as shown in FIG. 4 and FIG. 5, the assembly holes 1221 respectively restrict the movement of the first abutting plates 22 of the expansion cards 20 in the positive Z-axis direction, and the support lugs 1121 respectively limit the expansion cards 20 Second, the movement of the plate 23 in the positive Z-axis direction.

Next, please refer to FIG. 7 and FIG. 8. Figure 7 is a top plan view of the retaining member of Figure 6 in the release position. Figure 8 is a cross-sectional view of the retaining member of Figure 5 in a released position.

When the user needs to take out the expansion card 20 from the storage space 600, the user can apply the force to the limiting member 400 along the positive Y-axis to release the guiding post 500 from the limiting space 418. Then, the limiting member 400 is further pushed along the positive Y-axis to slide the second positioning structure 415 over the guiding post 500, so that the guiding post 500 is located in the limiting space 419 and is restricted by the second positioning structure 415. . At this time, the limiting members 400 are in the release position, and the stopping surfaces 416 are respectively spaced apart from the stopping structures 1122, and the projections 417 are respectively separated from the through holes 1122a (as shown in FIG. 5). When the limiting member 400 is in the release position, the limiting member 400 is disengaged from the second abutting plates 23 and the second abutting plates 23 are exposed. That is to say, the second abutting plates 23 have been limited by the infinite position member 400 in the positive X-axis direction, so that the user can take out the expansion card 20 from the storage space 600.

Conversely, when the user wants to replace the expansion card 20 into the storage space 600, the limiting member 400 must first be placed in the release position, and then the first abutting plates 22 are respectively inserted into the second covering portion in the negative X-axis direction. These assembly holes 1221 of 122 are simultaneously inserted into the slots 31 of the circuit board 30, respectively. Then, the limiting member 400 is pushed along the negative Y axis to move the limiting member 400 from the releasing position to the limiting position to prevent the second abutting plates 23 from being reversed from the assembly direction (positive X axis). Out of storage space 600.

In this embodiment, since the sliding direction of the limiting member 400 is orthogonal to the assembly direction of the assembly frame 21 of the expansion card 20, when the fixing frame assembly 10 is shaken or impacted, the limiting member 400 in the limiting position is not It is easy to slide to the release position with shaking or impact. Therefore, the sliding opening and closing limit member 400 can reduce the probability that the assembly frame 21 of the expansion card 20 can be disengaged from the fixing frame body 100 in the assembly direction.

In the present embodiment, the sliding direction of the limiting member 400 is orthogonal to the assembly direction of the mounting frame 21 of the expansion card 20, and is not intended to limit the present invention. In other embodiments, under the premise that the sliding direction of the limiting member is not parallel to the assembly direction of the assembly frame, the limiting member can also provide a limiting effect on the reverse direction of the assembly direction of the assembly frame.

In addition, the first positioning structure 414 and the second positioning structure 415 can remind the user where the limiting member 400 is located. In detail, when the guide post 500 is restrained by the first positioning structure 414, it can be known that the limiting member 400 is in the limit position. Similarly, when the guide post 500 is restrained by the second positioning structure 415, it can be known that the limiting member 400 is in the release position.

In this embodiment, the first positioning structure 414 and the second positioning structure 415 are located in the first guiding slot 413, but are not limited thereto. In other embodiments, the first positioning structure and the second positioning structure can be located in the second guiding slot. Alternatively, the first guiding slot and the second guiding slot have a first positioning structure and a second positioning structure.

According to the fixing frame assembly disclosed in the above embodiment, since the sliding direction of the limiting member is orthogonal to the assembly direction of the assembly frame of the expansion card, when the fixing frame assembly is shaken or impacted, the limiting member at the limiting position is not It is easy to slide to the release position with shaking or impact. Therefore, the sliding opening and closing limit member can reduce the probability that the expansion card assembly frame can be disengaged from the fixing frame body in the assembly direction.

When the limiting member is in the limiting position, the second abutting plate of the mounting frame of the expansion card is limited between the limiting frame and the second bearing portion, so that the expansion card is opposite in the assembly direction. The movement to the (positive X-axis) is restricted, so that the expansion cards can be prevented from being separated from the storage space by the reverse direction of the assembly direction and separated from the slots of the boards.

Furthermore, the bearing strips, the third bearing portion of the second bearing portion and the assembly holes limit the movement of the first abutment plates of the expansion cards in the positive Y-axis, and the support lugs limit the expansion cards The movement of the second abutment plates in the positive Y-axis direction and the abutment plates respectively limit the movement of the first abutment plates of the expansion cards in the negative Y-axis direction.

In addition, the assembly holes respectively limit the movement of the first abutment plates of the expansion cards in the positive Z-axis, and the lugs respectively limit the movement of the second abutment plates of the expansion cards in the positive Z-axis direction.

While the present invention has been described above in terms of the preferred embodiments thereof, it is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention.
