Description

Fixing frame assembly

Technical Field

The present invention relates to a fixing frame assembly, and more particularly, to a fixing frame assembly having a slidable stopper.

Background

In order to meet the requirements of an electronic device (e.g., a desktop computer, a notebook computer, or a server), a user usually inserts an expansion card into an expansion slot of a board of the electronic device to enhance the performance of the electronic device. The expansion card is, for example, a display adapter, a network card, a sound card, or a memory.

Generally, the expansion card is usually disposed on a board of the electronic device through a carrier, and the carrier is further matched with the rotating fastener to limit the expansion card by the rotating fastener. However, since the opening and closing of the rotating fastener is performed by rotating, when the electronic device is shocked or bumped, the rotating fastener is easily rotated relative to the carrier, and is separated from the original position for limiting the expansion card, so that the expansion card is not limited by the rotating fastener, and the expansion card may be separated from the expansion slot along with the shocking or bumping.

Disclosure of Invention

The present invention provides a fixing frame assembly to solve the problem that a rotating fastener for opening and closing is easily separated from an expansion card when an electronic device is shocked or bumped in the prior art.

According to the fixing frame assembly disclosed in the above embodiment, since the sliding direction of the limiting member is not parallel to the assembling direction of the assembling frame of the expansion card, when the fixing frame assembly is shaken or impacted, the limiting member at the limiting position is not easy to slide to the releasing position along with shaking or impacting. Therefore, the limiting piece which is opened and closed in a sliding mode can reduce the probability that the assembly frame of the expansion card is separated from the fixing frame body along the assembly direction.

The above description of the present invention and the following description of the embodiments are provided to illustrate and explain the spirit and principles of the present invention and to provide further explanation of the invention as claimed in the appended claims.

The holder body 100 includes a support frame 110 and a mask frame 120. The support frame 110 includes a first support portion 111, a second support portion 112, a third support portion 113 and an assembly portion 114. The first bearing portion 111 includes a plurality of bearing strips 1111. Two opposite ends of each bearing strip 1111 are respectively connected to the second bearing portion 112 and the third bearing portion 113, and the assembling portion 114 is connected to one end of the third bearing portion 113 far away from the first bearing portion 111. The second receiving portion 112 and the assembling portion 114 extend in the same direction. The mask frame 120 includes a first mask portion 121 and a second mask portion 122. One of the bearing strips 1111, the second bearing portion 112, the third bearing portion 113 and the assembling portion 114 of the first bearing portion 111 are disposed on the first covering portion 121 and are located on the same side of the first covering portion 121. The assembling portion 114 of the support frame 110 is disposed on the second covering portion 122 at a side away from the second support portion 112. The second bearing portion 112 has a plurality of supporting lugs 1121 and a plurality of stopping structures 1122. The supporting lugs 1121 and the stopping structures 1122 extend away from the second covering portion 122, and each stopping structure 1122 has a through hole 1122a (please refer to fig. 5). In addition, the second cover portion 122 has a plurality of assembly holes 1221 and a plurality of abutting pieces 1222. The abutting pieces 1222 are respectively located beside the assembling holes 1221, and the abutting pieces 1222 extend toward the second bearing portion 112.

The first cover portion 121, the second cover portion 122, the first bearing portion 111 and the second bearing portion 112 together form a storage space 600, and the expansion cards 20 are stored in the storage space 600. Specifically, the first abutting plates 22 of the assembling racks 21 of the expansion cards 20 are respectively inserted into the assembling holes 1221 in the assembling direction D1, and the assembling direction D1 is parallel to the normal of the second covering portion 122. Two opposite sides of each first abutting plate 22 are abutted by two adjacent abutting strips 1111, the third abutting portion 113 and the abutting sheet 1222 respectively. In addition, the second abutting plate 23 of the assembling rack 21 of the expansion cards 20 abuts against one side of the second bearing portion 112 away from the assembling portion 114, and the supporting lugs 1121 are respectively located in the grooves 24 of the second abutting plate 23 of the assembling rack 21.

In the present embodiment, the arrangement of the plurality of expansion cards 20 stored in the storage space 600 is only for illustration, but not limited thereto. In other embodiments, the storage space may store only one expansion card.

The support frame 110 is not limited to the present invention, and the third support portion 113 is provided. In other embodiments, the bearing frame may be devoid of the third bearing portion. That is, the bearing strips of the first bearing portion can be directly connected to the assembling portion.

The two fastening structures 200 and the two locking structures 300 are disposed on the second cover portion 122 of the mask frame 120, and the circuit board 30 is fixed to the second cover portion 122 through the two fastening structures 200 and the two locking structures 300. In the present embodiment, the circuit board 30 and the two fastening structures 200 are combined by, for example, fastening, and the circuit board 30 and the two locking structures 300 are combined by, for example, screwing.

In the present embodiment, the circuit board 30 is fixed to the second cover portion 122 through two fastening structures 200 and two locking structures 300, but not limited thereto. In other embodiments, the structure for fixing the circuit board may be a locking structure or a locking structure. In addition, the number of the locking structures 200 and the number of the locking structures 300 are not limited to two. In other embodiments, the number of the locking structures and the number of the locking structures can be one or more than two.

In addition, the mask frame 120 of the present embodiment further includes a first guide portion 123, and the holder 110 further includes a second guide portion 115. The first guiding portion 123 is connected to the first covering portion 121, and the second guiding portion 115 is connected to an end of the second bearing portion 112 away from the first covering portion 121. The first guide portion 123 corresponds to the second guide portion 115.

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

The two opposite ends of the position-limiting element 400 are slidably disposed on the first guiding portion 123 and the second guiding portion 115, respectively, and the sliding direction D2 of the position-limiting element 400 is orthogonal to the assembling direction D1 of the expansion card 20, for example. In detail, the position limiting member 400 includes a frame portion 410 and a spring portion 420 connected to each other. 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 spring portion 420 are slidably disposed on the second guiding portion 115. The frame portion 410 has a lateral surface 411, a guiding slope 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 bumps 417. The side surface 411 is connected to the inclined guide 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 flanges, for example. The first positioning structure 414 and the second positioning structure 415 are respectively located at two opposite sides of the first guiding groove 413, and the first positioning structure 414 and the second positioning structure 415 respectively form a limiting

space

418, 419 with the sidewall of the two opposite sides of the first guiding groove 413. The guiding column 500 is disposed through the first guiding portion 123, and a portion of the guiding column 500 is located in the first guiding groove 413. The stop surfaces 416 respectively face the stop structures 1122, and the bumps 417 respectively protrude from the stop surfaces 416. 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 in 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 slope 412 can be abutted against the first guiding portion 123, and then the limiting member 400 is assembled between the first guiding portion 123 and the second guiding portion 115 by the elasticity of the elastic piece portion 420. Therefore, the installation of the inclined guide surface 412 and the elastic sheet portion 420 is helpful to improve the assembly convenience of the position limiting member 400. However, the arrangement of the guiding inclined plane 412 and the elastic sheet portion 420 is not intended to limit the present invention. In other embodiments, a side of the frame portion facing the first guiding portion may be a plane, and the limiting member may have no elastic piece portion.

In the present embodiment, the limiting member 400 can slide between a limiting position and a releasing position. The relationship between the elements when the position limiting member 400 is at the limiting position will be explained first.

As shown in fig. 5 and 6, when the position-limiting member 400 is located at the position-limiting position, the guiding post 500 is limited in the position-limiting space 418 by the first positioning structure 414, the stopping surfaces 416 of the frame body 410 respectively abut against the stopping structures 1122, and the protrusions 417 respectively penetrate through the through holes 1122a of the stopping structures 1122. At this time, the limiting member 400 stops at a side of the second bearing portion 112 (shown in fig. 2) far from the second cover portion 122 (shown in fig. 2), and the limiting member 400 abuts against the second abutting plates 23 of the assembling frames 21 and shields a portion of the second abutting plates 23 of the assembling frames 21.

For clarity of description, the expansion cards 20 are limited in the storage space 600, an X-axis, a Z-axis and a Y-axis are defined, which are orthogonal to each other. The X axis direction is a direction parallel to the normal line of the second cover portion 122, and the Z axis direction is a direction parallel to the normal line of the first cover portion 121.

As shown in fig. 2 and 5, when the position-limiting element 400 is located at the position-limiting position, the second abutting plates 23 of the assembly racks 21 are limited between the position-limiting element 400 and the second bearing portion 112, so that the movement of the expansion cards 20 in the positive X-axis direction is limited, and therefore the expansion cards 20 can be prevented from being separated from the slots 31 of the circuit boards 30 by coming out of the storage space 600 from the positive X-axis direction.

Furthermore, as shown in fig. 2 and 3, the bearing strips 1111, the third bearing portions 113 and the assembling holes 1221 of the first bearing portion 111 limit the movement of the first abutting plates 22 of the expansion cards 20 in the positive Y-axis direction, the supporting lugs 1121 limit the movement of the second abutting plates 23 of the expansion cards 20 in the positive Y-axis direction, and the abutting pieces 1222 limit the movement of the first abutting plates 22 of the expansion cards 20 in the negative Y-axis direction, respectively.

In addition, as shown in fig. 4 and 5, the assembling holes 1221 respectively limit the movement of the first abutting plates 22 of the expansion cards 20 in the positive Z-axis direction, and the supporting lugs 1121 respectively limit the movement of the second abutting plates 23 of the expansion cards 20 in the positive Z-axis direction.

Please refer to fig. 7 and 8. Fig. 7 is a top view of the limiting member of fig. 6 in a releasing position. Fig. 8 is a cross-sectional view of the retaining member of fig. 5 in a release position.

When the user needs to take the expansion cards 20 out of the storage space 600, the user can apply a force to the position-limiting member 400 along the positive Y-axis direction by hand to disengage the guiding post 500 from the position-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 limited by the second positioning structure 415. At this time, the position-limiting element 400 is located at the releasing position, the stopping surfaces 416 are respectively kept at a distance from the stopping structures 1122, and the bumps 417 are respectively disengaged from the through holes 1122a (as shown in fig. 5). When the limiting member 400 is located at the releasing position, the limiting member 400 is separated from the second abutting plates 23, and the second abutting plates 23 are exposed. That is, the second abutting plates 23 are not limited by the limiting member 400 in the positive X-axis direction, so that the user can take out the expansion cards 20 from the storage space 600.

Conversely, when the user wants to put the expansion cards 20 back into the storage space 600, the position-limiting member 400 is first located at the releasing position, and then the first abutting plates 22 are respectively inserted into the assembling holes 1221 of the second covering portion 122 along the negative X-axis direction, and the expansion cards 20 are respectively inserted into the slots 31 of the circuit board 30. 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, so as to prevent the second abutting plates 23 from being released from the storage space 600 from the reverse direction (positive X axis) of the assembling direction.

In the embodiment, since the sliding direction of the position-limiting element 400 is orthogonal to the assembling direction of the assembling rack 21 of the expansion card 20, when the fixing rack assembly 10 is shaken or bumped, the position-limiting element 400 at the position-limiting position is not easy to slide to the releasing position along with the shaking or bumping. Therefore, the sliding opening and closing position-limiting member 400 can reduce the probability that the assembly rack 21 of the expansion card 20 is separated from the fixing rack body 100 along the assembly direction.

In the present embodiment, the sliding direction of the position-limiting element 400 is orthogonal to the assembling direction of the assembling rack 21 of the expansion card 20, and is not intended to limit the present invention. In other embodiments, on the premise that the sliding direction of the position-limiting member is not parallel to the assembling direction of the assembling frame, the position-limiting member can provide the position-limiting effect in the reverse 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-limiting member 400. In detail, when the guiding column 500 is limited by the first positioning structure 414, it is known that the limiting member 400 is located at the limiting position. Similarly, when the guiding column 500 is limited by the second positioning structure 415, it is known that the limiting member 400 is located at the releasing position.

In the embodiment, the first positioning structure 414 and the second positioning structure 415 are located in the first guiding groove 413, but not limited thereto. In other embodiments, the first positioning structure and the second positioning structure can be located in the second guiding groove instead. Or the first guide groove and the second guide groove are both provided with a first positioning structure and a second positioning structure.

According to the fixing frame assembly disclosed in the above embodiments, since the sliding direction of the limiting member is orthogonal to the assembling direction of the assembling frame of the expansion card, when the fixing frame assembly is shaken or impacted, the limiting member at the limiting position is not easy to slide to the releasing position along with the shaking or impacting. Therefore, the limiting piece which is opened and closed in a sliding mode can reduce the probability that the assembly frame of the expansion card is separated from the fixing frame body along the assembly direction.

Under the condition that the limiting piece is positioned at the limiting position, the second abutting plate of the assembling frame of the expansion cards is limited between the limiting frame and the second bearing part, so that the movement of the expansion cards in the reverse direction (positive X-axis direction) of the assembling direction is limited, and the expansion cards can be prevented from being separated from the storage space and separated from the slots of the circuit boards from the reverse direction of the assembling direction.

Furthermore, the bearing strips, the third bearing parts and the assembling holes of the second bearing parts limit the movement of the first abutting plates of the expansion cards in the positive Y-axis direction, the supporting lugs limit the movement of the second abutting plates of the expansion cards in the positive Y-axis direction, and the abutting pieces respectively limit the movement of the first abutting plates of the expansion cards in the negative Y-axis direction.

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

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
