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, a containing seat 500, an elastic component 600 and a positioning element 700.
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 301, a side cover 302 and a slide groove 303. The side cover plate 302 is connected to the additional circuit board 301 to surround the chute 303 together with the additional circuit board 301. The sliding slot 303 is used for sliding the expansion card 100 to mount the expansion card 100 to the slot 202 of the circuit board 200.
The accommodating seat 500 is disposed on a side of the side cover plate 302 of the first slide rail 300 away from the second slide rail 400, and includes an installation groove 501 and a communication opening 502. The mounting groove 501 is communicated with the sliding groove 303 of the first sliding rail 300 through a communication port 502.
In addition, in the embodiment, the accommodating seat 500 is integrally formed with the first slide rail 300, but the invention is not limited thereto. In other embodiments, the accommodating seat and the first slide rail are combined.
The elastic element 600 is disposed on the accommodating seat 500 and located in the mounting groove 501. Further, the elastic member 600 is, for example, a compression spring.
The positioning member 700 includes a movable portion 701, a locking portion 702, an operation portion 703, and a mounting post 704.
The locking portion 702 protrudes from the movable portion 701. The movable portion 701 is slidably disposed in the mounting groove 501 of the accommodating seat 500 and can be far away from or close to the sliding groove 303 of the first sliding rail 300. Therefore, when the movable portion 701 approaches the sliding groove 303 of the first slide rail 300, the locking portion 702 passes through the communication opening 502 and is located in the sliding groove 303 of the first slide rail 300, so that the locking portion 702 is used to lock with the card slot 101 of the expansion card 100. When the movable portion 701 moves away from the sliding slot 303 of the first sliding rail 300, the locking portion 702 retracts into the mounting slot 501 of the accommodating seat 500. Further, in the extending direction D2 of the slide groove 303 of the first slide rail 300, the width W1 of the mounting groove 501 is larger than the width W2 of the movable portion 701 and the width W2 of the movable portion 701 is larger than the width W3 of the communication port 502.
In the present embodiment, the extending direction D1 of the locking portion 702 is orthogonal to the extending direction D2 of the sliding slot 303 of the first slide rail 300. That is, the extending direction D1 and the extending direction D2 are orthogonal to each other or the difference between the included angle between the extending direction D1 and the extending direction D2 and 90 degrees is negligible, but the invention is not limited thereto. In other embodiments, the extending direction of the fastening portion and the extending direction of the sliding groove of the first sliding rail form an acute angle.
Furthermore, in the present embodiment, the fastening portion 702 includes a guiding inclined plane 7020, and the guiding inclined plane 7020 faces away from the slot 202 of the circuit board 200. However, the locking portion 702 is not limited to include the guiding inclined surface 7020, and in other embodiments, the locking portion need not include a guiding inclined surface.
However, the housing seat 500 is not limited to including the communication port 502. In other embodiments, the accommodating seat does not include a communication port, so that the mounting groove is directly communicated with the sliding groove of the first sliding rail, and the fastening portion passes through the mounting groove and is located in the sliding groove of the first sliding rail.
The operation portion 703 is connected to one side of the movable portion 701 and partially located outside the mounting groove 501. The mounting post 704 and the locking portion 702 are located at two opposite sides of the movable portion 701, and two opposite ends of the elastic component 600 respectively abut against the accommodating seat 500 and are sleeved on the mounting post 704.
However, the positioning member 700 is not limited to include the operation portion 703 and the mounting post 704. In other embodiments, the positioning member includes an operating portion and a mounting post, and the movable member is operated by a handle disposed on the movable portion, and one end of the elastic member is adhered to a side of the movable portion away from the fastening portion.
In addition, in the present embodiment, the circuit assembly 10 further includes two baffles 720. The two baffles 720 are disposed on the accommodating seat 500 and located in the mounting groove 501, and stop at one side of the movable portion 701. However, the circuit assembly 10 is not limited to including two baffles 720. In other embodiments, the circuit assembly does not include two baffles.
For convenience of description, the following description only describes the operation process of the expansion card 100 being mounted in the slot 202 of the circuit board 200 by using the first slide rail 300, the accommodating seat 500, the elastic component 600 and the positioning component 700.
As shown in fig. 4, when the expansion card 100 slides into the sliding slot 303 of the first sliding rail 300 along the inserting direction D3, the expansion card 100 pushes down the guiding inclined surface 7020 of the locking portion 702 to make the locking portion 702 retract from the sliding slot 303 toward the mounting slot 501 of the accommodating seat 500, so as to drive the movable portion 701 to compress the elastic element 600. When the locking portion 702 retracts from the sliding groove 303 toward the mounting groove 501 of the accommodating seat 500, the expansion card 100 can continue to slide into the sliding groove 303 of the first sliding rail 300 along the inserting direction D3.
Next, referring to fig. 5 to 6, fig. 5 is a perspective view showing that the expansion card is inserted into a slot of the circuit board. Fig. 6 is a schematic cross-sectional view showing the locking portion being locked to the slot of the expansion card.
As shown in fig. 5 and fig. 6, when the expansion card 100 is mounted in the slot 202 of the circuit board 200, the compressed elastic component 600 releases the elastic potential to push the movable portion 701, so as to drive the locking portion 702 to extend out of the mounting slot 501 and be locked in the locking slot 101 of the expansion card 100.
Referring to fig. 2, 5 and 7, fig. 7 is a schematic cross-sectional view showing the locking portion being separated from the card slot of the expansion card.
When the operating portion 703 is pushed and the movable portion 701 drives the locking portion 702 to retract from the sliding slot 303 toward the mounting slot 501 of the accommodating seat 500, the locking portion 702 is separated from the slot 101 of the expansion card 100. When the locking portion 702 is disengaged from the card slot 101 of the expansion card 100, the expansion card 100 can be pulled in a removing direction D4 opposite to the inserting direction D3 in fig. 4 to be removed from the slot 202 of the circuit board 200, and further slide out of the sliding slot 303 of the first sliding rail 300.
