In the present embodiment, the circuit assembly 10 includes an expansion card 100, a circuit board 200, and an expansion card fixing structure 250. The circuit board 200 includes a board body 201 and a slot 202. The board body 201 of the circuit board 200 has a top surface 203, a bottom surface 204, a slot 205, a first wall surface 206 and a second wall surface 207. The top surface 203 and the bottom surface 204 face away from each other. The slot 205 extends through the top surface 203 and the bottom surface 204. The first wall 206 and the second wall 207 are located in the slot 205 and face each other. The slot 202 is disposed on the board body 201 and located in the slot 205. The expansion card 100 is received in the slot 205.
In the present embodiment, the expansion card fixing structure 250 includes a first slide rail 300, a second slide rail 400, and a first locking member 500. The expansion card fixing structure 250 may further include an elastic member 600.
The first slide rail 300 and the second slide rail 400 are respectively fixed on the first wall 206 and the second wall 207 of the circuit board 200, and are used for the expansion card 100 to slide.
However, the circuit board 200 is not limited to including the slot 205, and in other embodiments, the circuit board does not include a slot. Further, in the embodiment where the circuit board does not include the slot, the first slide rail and the second slide rail are disposed on the top surface of the circuit board instead.
Since the first slide rail 300 and the second slide rail 400 are similar in structure, only the detailed structure of the first slide rail 300 is illustrated below for convenience of description.
The first slide rail 300 includes an additional circuit board 310 and a cover plate 320. The cover plate 320 is connected to the additional circuit board 310 to surround the chute 330 together with the additional circuit board 310. The sliding slot 330 is used for sliding the expansion card 100 to mount the expansion card 100 to the slot 202 of the circuit board 200.
The cover plate 320 of the first slide rail 300 includes a through slot 321. The through slot 311 is located on a side of the sliding slot 330 away from the additional circuit board 310, and extends toward the additional circuit board 310 to communicate with the sliding slot 330.
The first locking element 500 includes a first operating portion 510, a first pivot portion 520 and a first locking portion 530. The first operating portion 510 and the first locking portion 530 are respectively connected to two opposite sides of the first pivot portion 520. The first pivot portion 520 is pivotally connected to the cover 320. The first operating portion 510 is used to drive the first buckling portion 530 to move between a buckling position and a releasing position. When the first locking portion 530 is located at the locking position, the first locking portion 530 is located in the sliding slot 330 of the first sliding rail 300 for being locked with the card slot 101 of the expansion card 100. When the first locking portion 530 is located at the releasing position, the first locking portion 530 is separated from the sliding slot 330 of the first sliding rail 300 to be separated from the card slot 101 of the expansion card 100.
In the present embodiment, the first operating portion 510, the first pivot portion 520 and the first fastening portion 530 are integrally formed to simplify the assembly process of the expansion card fixing structure 250, but not limited thereto. In other embodiments, the first operating portion, the first pivot portion and the first buckle portion may also be detachable assemblies.
In the present embodiment, the first locking member 500 is located on a side of the sliding groove 330 of the first sliding rail 300 away from the additional circuit board 310 of the first sliding rail 300, but not limited thereto. In other embodiments, the first fastener may also be located on the other sides of the sliding groove of the first sliding rail.
In this embodiment, one end of the elastic element 600 is assembled to the first locking element 500, and the other end of the elastic element 600 is assembled to the first slide rail 300. The elastic member 600 is used to drive the fastening portion 530 of the first fastening member 500 to be located at the fastening position.
In this embodiment, the fastening portion 530 of the first fastening member 500 may further include a guiding inclined surface 531. The lead slope 531 faces away from the slot 202 of the circuit board 200.
For convenience of description, the following description only uses the first slide rail 300, the first locking member 500 and the elastic member 600 to describe the operation process of the expansion card 100 being mounted in the slot 202 of the circuit board 200.
Please refer to fig. 5. FIG. 5 is a cross-sectional view of the first locking member of FIG. 4 pushed by the expansion card. As shown in fig. 5, when the expansion card 100 slides into the sliding slot 330 of the first sliding rail 300 along the inserting direction D1, the expansion card 100 pushes down the guiding inclined surface 531 of the fastening portion 530 of the first locking member 500, so that the fastening portion 530 of the first locking member 500 retracts in a direction away from the additional circuit board 310 to be located at the releasing position. When the fastening portion 530 of the first fastening member 500 is lifted in the direction a away from the additional circuit board 310, the expansion card 100 can continue to slide into the sliding slot 330 of the first sliding rail 300 along the inserting direction D1.
Next, referring to fig. 6, fig. 6 is a schematic cross-sectional view of the first locking member of fig. 4 being locked to a slot of the expansion card. As shown in fig. 6, when the expansion card 100 is mounted to the slot 202 of the circuit board 200, since the slot 101 of the expansion card 100 is aligned with the position of the fastening portion 530 of the first locking member 500, the first locking member 500 is pulled by gravity to move the fastening portion 530 of the first locking member 500 from the releasing position to the locking position (along the direction B). That is, the locking portion 530 of the first locking member 500 moves toward the additional circuit board 310 and is engaged with the card slot 101 of the expansion card 100.
In the embodiment, only the first slide rail 300 is provided with the first locking element 500 and the elastic element 600, but not limited thereto. Referring to fig. 7, fig. 7 is an exploded view of a circuit assembly according to a second embodiment of the invention.
In the present embodiment, the expansion card fixing structure 250a of the circuit assembly 10a includes a first slide rail 300, a second slide rail 400a, a first fastener 500, a second fastener 500a, and two elastic members 600 and 600 a. Since the second slide rail 400a, the second locking element 500a and the elastic element 600a have similar structures and connections to the first slide rail 300, the first locking element 500 and the elastic element 600, further description is omitted.
According to the expansion card mounting structure disclosed by the embodiment, through the design that the clamping part is pivoted on the first sliding rail, a user can drive the clamping part of the clamping part to move from the clamping position to the releasing position by pressing the operating part of the clamping part, so that the expansion card can conveniently slide into the sliding groove and be inserted into the slot. Or the operating part of the buckle piece is pulled and lifted to drive the buckle part of the buckle piece to return to the buckle position from the release position.
In some embodiments, the elastic member is used to allow the locking member to automatically return to the locking position from the releasing position in an unstressed state, so as to simplify the operation process of a user.
In some embodiments, the locking member has a guiding slope, so that the guiding slope of the locking member is pushed by the expansion card to move from the locking position to the releasing position in the process of sliding the expansion card into the sliding slot. That is to say, the buckle part can move to the release position from the buckle position by itself without the driving of the operating part.
Although the embodiments of the present invention have been described above, the description is not intended to limit the scope of the invention. Workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the disclosure. The scope of the present invention is defined by the appended claims.
