Description

Fixing frame assembly

The invention relates to a fixing frame assembly, in particular to a fixing frame assembly with a slidable limiting member.

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

Generally speaking, most expansion cards are installed 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 rotating fastener is opened and closed by rotation, when the electronic device is shocked or impacted, the rotating fastener is easy to rotate relative to the carrier, and is disengaged from the position of the original limit expansion card, making the expansion card parallel Without being limited by the rotation fastener, the expansion card may be separated from the expansion slot with vibration or impact.

The present invention is to provide a fixing frame assembly, so as to solve the problem that the rotating fastener in the prior art can be easily disengaged from the expansion card when the electronic device is subjected to vibration or impact.

A fixing frame assembly disclosed in an embodiment of the present invention is used to install an assembly frame of an expansion card. The fixing frame assembly includes a fixing frame body and a limiting member. The fixing frame body includes a bearing frame.

The limiting member is slidably installed on the fixing frame body, and the limiting member can slide between a limiting position and a releasing position. The sliding direction of the stopper is not parallel to the assembly direction of the assembly frame. When the limiter is in the limit position, the limiter is stopped on one side of the bearing frame and used to abut the assembly frame. When the limiter is in the release position, the limiter is used to disengage from the assembly frame.

According to the fixing bracket assembly disclosed in the above embodiment, since the sliding direction of the limiting member is not parallel to the assembly direction of the assembly rack of the expansion card, when the fixing bracket assembly is shaken or hit, 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 limiter can reduce the probability that the assembly frame of the expansion card is pulled out of the fixing frame body in the assembly direction.

Next, please refer to FIG. 2, FIG. 5 and FIG. 6 together. 5 is a schematic cross-sectional view of FIG. 1. 6 is a schematic top view of FIG. 1.

The two opposite ends of the limiting member 400 are respectively slidably disposed on the first guide portion 123 and the second guiding portion 115, 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 frame body 410 and an elastic piece 420 connected to each other. One end of the frame body portion 410 is slidably disposed on the first guide portion 123, and the other end of the frame body portion 410 and the elastic piece portion 420 are slidably disposed on the second guide portion 115. The frame body 410 has a side surface 411, a sloped surface 412, a first guide groove 413, a first positioning structure 414, a second positioning structure 415, a plurality of stop surfaces 416 and a plurality of protrusions 417. The side surface 411 is connected to the inclined surface 412 and faces the first guide portion 123, and the first guide 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 groove 413, and the first positioning structure 414 and the second positioning structure 415 are respectively opposite to the side walls of the first guiding groove 413 A limit space 418, 419 is formed. The guide post 500 is passed through the first guide portion 123, and a part of the guide post 500 is located in the first guide groove 413. The stop surfaces 416 respectively face the stop structures 1122, and the protrusions 417 protrude from the stop surfaces 416, respectively. The elastic piece portion 420 has a guide protrusion 421, the second guide portion 115 further has a second guide groove 1151, and the guide protrusion 421 is slidably located in the second guide groove 1151.

In the process of assembling the stopper 400 to the first guide portion 123 and the second guide portion 115, the inclined surface 412 can be pressed against the first guide portion 123, and then through the elasticity of the elastic piece portion 420, the The stopper 400 is assembled between the first guide portion 123 and the second guide portion 115. Therefore, the arrangement of the inclined surface 412 and the elastic piece portion 420 helps to improve the ease of assembly of the limiting member 400. However, the arrangement of the inclined surface 412 and the elastic piece 420 is not intended to limit the present invention. In other embodiments, the side of the frame body facing the first guiding portion may be only a flat surface, and the position-limiting member may not have an elastic sheet portion.

In this embodiment, the limiting member 400 can slide between a limiting position and a releasing position. Hereinafter, the relationship between the components when the limiting member 400 is located at the limiting position will be described first.

As shown in FIGS. 5 and 6, when the limiter 400 is located at the limit position, the guide post 500 is limited to the limit space 418 by the first positioning structure 414, and the stop surfaces 416 of the frame body 410 The stop structures 1122 and the protrusions 417 respectively penetrate the through holes 1122 a 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 these assembly frames The second abutting plate 23 of 21, and shields the parts of the second abutting plate 23 of these assembly frames 21.

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

As shown in FIGS. 2 and 5, when the limiting member 400 is located at the limiting position, the second abutment plates 23 of these assembly frames 21 will be limited between the limiting member 400 and the second bearing portion 112 In order to limit the movement of the expansion cards 20 in the positive X axis, the expansion cards 20 can be prevented from being separated from the storage space 600 from the positive X axis and separated from the slots 31 of the circuit boards 30.

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

In addition, as shown in FIGS. 4 and 5, the assembly holes 1221 respectively restrict the movement of the first abutment plates 22 of the expansion cards 20 in the positive Z-axis direction, and the support lugs 1121 respectively restrict the number of the expansion cards 20. The second abutment plate 23 moves in the positive Z axis.

Next, please refer to FIG. 7 and FIG. 8. 7 is a schematic plan view of the limiting member of FIG. 6 when it is in the release position. 8 is a schematic cross-sectional view of the limiting member of FIG. 5 when it is in the release position.

When the user needs to take these expansion cards 20 out of the storage space 600, the user can apply force to the limiting member 400 along the positive Y axis through the hand to disengage the guide post 500 from the limiting space 418. Then, continue to push the limiting member 400 along the positive Y axis, so that the second positioning structure 415 slides past the guide post 500, and the guide post 500 is located in the limiting space 419 and is limited by the second positioning structure 415 . At this time, the stopper 400 is at the release position, and the stop surfaces 416 are kept at a distance from the stop structures 1122, and the protrusions 417 are separated from the through holes 1122a (as shown in FIG. 5). When the position-limiting member 400 is in the release position, the position-limiting member 400 will be detached from the second abutment plates 23 and allow the second abutment plates 23 to be exposed. That is to say, these second abutment plates 23 have been limited by the infinite member 400 in the positive X axis direction, so the user can take out the expansion cards 20 from the storage space 600.

On the contrary, when the user wants to install the expansion cards 20 back to the storage space 600, the limiter 400 must be placed in the release position first, and then the first abutment plates 22 are inserted into the second cover parts along the negative X axis respectively The assembly holes 1221 of 122, and the expansion cards 20 are inserted into the slots 31 of the circuit board 30, respectively. Next, the limiter 400 is pushed along the negative Y axis to move the limiter 400 from the release position to the limit position to prevent the second abutment plates 23 from coming out of 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 hit, the limiting member 400 at the limiting position does not It is easy to slide to the release position with shaking or impact. Therefore, the sliding-opening limiter 400 can reduce the probability that the assembly frame 21 of the expansion card 20 is pulled out of the fixing frame body 100 in the assembly direction.

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

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

In this embodiment, the first positioning structure 414 and the second positioning structure 415 are located in the first guiding groove 413, but it is not limited thereto. In other embodiments, the first positioning structure and the second positioning structure may be located in the second guiding groove. Or, both the first guiding groove and the second guiding groove have a first positioning structure and a second positioning structure.

According to the fixing bracket assembly disclosed in the above embodiment, since the sliding direction of the limiting member is orthogonal to the assembly direction of the assembly rack of the expansion card, when the fixing bracket assembly is shaken or hit, the limiting member at the limiting position does not It is easy to slide to the release position with shaking or impact. Therefore, the sliding opening and closing limiter can reduce the probability that the assembly frame of the expansion card is pulled out of the fixing frame body in the assembly direction.

When the limiter is located at the limit position, the second abutment plate of the assembly frame of these expansion cards will be limited between the limit frame and the second bearing portion, so that these expansion cards are reversed in the assembly direction The movement in the (positive X axis) direction is restricted, so that these expansion cards can be prevented from being separated from the storage space and separated from the slots of these circuit boards from the reverse direction of the assembly direction.

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

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.

Although the present invention is disclosed as the above preferred embodiments, it is not intended to limit the present invention. Any person familiar with similar arts can make some changes and modifications without departing from the spirit and scope of the present invention. The scope of patent protection for inventions shall be subject to the scope defined in the patent application scope attached to this specification.
