Referring to fig. 1 to 4, fig. 1 is a schematic diagram of a circuit module 100 according to an embodiment of the invention, fig. 2 and 3 are exploded views of the circuit module 100 in fig. 1 locked on a base board 200 by a plurality of locking members S, and fig. 4 is a partially enlarged schematic diagram of the expansion card 120, the base board 200 and the flexible member 200 in fig. 3.

As shown in fig. 1 to 3, the circuit module 100 and the bottom board 200 in the present embodiment can be combined with each other by a plurality of locking members S and disposed inside a notebook computer or a tablet computer, wherein the circuit module 100 includes a circuit board 110, an Expansion card 120(Expansion card) and a connector 130, the connector 130 is disposed at one side of the circuit board 110, and the Expansion card 120 is inserted into the connector 130, so that the Expansion card 120 can be electrically connected to the circuit board 110 through the connector 130.

In the present embodiment, the expansion card 120 may be a wireless network card (e.g., Wifi card), and is detachably coupled to the connector 130 on one side of the circuit board 110.

As shown in fig. 2 and 3, the bottom plate 200 has a substantially rectangular structure, and a plurality of protruding columns 201 are formed on the bottom plate 200. During actual assembly, a plurality of locking members S (e.g., screws) may be inserted through the through holes 111 of the circuit board 110 and locked into the concave holes at the center of the protruding pillars 201, so that the circuit board 110 can be stably locked on the bottom plate 200.

In addition, as shown in fig. 2 to 4, an arc-shaped groove 121 is formed at the edge of the expansion card 120, the position of the arc-shaped groove 121 corresponds to one of the protruding columns 201 on the bottom plate 200, and the groove 121 and the connector 130 are located on the opposite side of the expansion card 120.

In actual assembly, a flexible member R (e.g., a rubber washer) is sleeved around the boss 201, and then a locking member S (e.g., a screw) is inserted through the groove 121 and locked into the recess hole at the center of the boss 201, so that the expansion card 120 can be fixed on the base plate 200. In the present embodiment, the connector 130, the expansion card 120 and the flexible member R are arranged along a long axis direction (X axis direction) of the rectangular base plate 200.

It should be noted that the circuit module 100, the bottom plate 200, the flexible member R and the locking member S can be combined together to form an electrical connection assembly, which can be disposed inside a notebook computer or a tablet computer for performing functions such as digital data operation, signal processing or wireless communication.

As shown in fig. 4, the convex column 201 on the base plate 200 is formed with a bottom 2010 and an extension 2011 connected to each other, wherein the extension 2011 extends and protrudes from the bottom 2010 toward the Z-axis direction, and a width of the bottom 2010 is greater than a width of the extension 2011. It should be understood that, during assembly, the flexible member R is first sleeved around the outside surface of the extension 2011, and a portion (protrusion R2) of the flexible member R extends into the groove 121 of the expansion card 120, and then a locking member S is locked into the recess 2012 at the center of the protrusion 201, so that the expansion card 120 can be fixed on the base plate 200.

Fig. 5 is a schematic view of the flexible member R in fig. 4, fig. 6 is a partial sectional view of the locking member S locked in the recess 2012 formed at the center of the boss 201 and contacting the flexible member R, and fig. 7 is a partial sectional view of the locking member S further locked in the recess 2012 formed at the center of the boss 201 and pressing the flexible member R.

As shown in fig. 4 to 7, the flexible member R of the present embodiment has an annular body R1 and a protrusion R2, wherein the protrusion R2 protrudes from the body R1 along the-X axis (horizontal direction) and extends into the groove 121 of the expansion card 120.

In addition, as can be seen from fig. 6, before the locking member S is completely locked into the concave hole 2012 at the center of the convex pillar 201, the flexible member R protrudes out of the end of the convex pillar 201 in the Z-axis direction (vertical direction); that is, the height of the flexible member R in the Z-axis direction (vertical direction) is higher than the height of the convex pillar 201 in the Z-axis direction (vertical direction).

Then, as shown in fig. 7, when the locking member S is further locked into the recess 2012 at the center of the protrusion 201 in the-Z axis direction, the flexible member R is pressed by the locking member S, and a portion (protrusion R2) of the flexible member R deforms in the direction of the groove 121 and presses the expansion card 120 in the-X axis direction (horizontal direction), so that the expansion card 120 can be tightly combined with the connector 130, and the expansion card 120 is prevented from being loosened or displaced relative to the connector 130 or the chassis 200.

It should be understood that, as shown in fig. 6 and 7, the bottom 2011 of the stud 201 forms a bearing surface T, the bearing surface T is adjacent to the outer surface of the extension 2012, and the expansion card 120 and the flexible member R are disposed on the bearing surface T. In this way, when the locking member S is completely locked into the recess 2012 at the center of the protruding pillar 201 in the-Z-axis direction, the expansion card 120 can be stably clamped between the locking member S and the bearing surface T of the protruding pillar 201 in the vertical direction (Z-axis direction), so as to further prevent the expansion card 120 from being loosened or displaced relative to the connector 130 or the bottom board 200.

Referring to fig. 8, fig. 8 is a partial cross-sectional view of the expansion card 120 clamped between the flexible member R and the connector 130. As shown in fig. 8, after the locking member S is completely locked into the recess 2012 at the center of the protrusion 201, the flexible member R is pressed by the locking member S to deform along the-X axis (horizontal direction) and push the expansion card 120, so that the expansion card 120 is tightly clamped between the flexible member R and the connector 130 in the horizontal direction, thereby effectively preventing the expansion card 120 from being loosened or displaced relative to the connector 130 or the bottom board 200.

It should be noted that, because the groove 121 in the present embodiment has an arc-shaped structure, when the flexible member R is pressed by the locking member S, a portion of the flexible member R (the protrusion R2) can be tightly adhered to the arc surface inside the groove 121, so as to prevent the expansion card 120 from being displaced on the XY plane relative to the connector 130 or the bottom board 200.

To sum up, the present invention provides an electrical connection assembly, wherein a flexible member R is sleeved around the convex pillar 201 of the bottom plate 200, and a locking member S (e.g. a screw) is inserted into the concave hole 2012 at the center of the convex pillar 201 through the flexible member R, so that a portion of the flexible member R is pressed by the locking member S and deforms and extrudes the expansion card 120 toward the groove 121. In this way, the expansion card 120 can be tightly combined with the connector 130 to prevent the expansion card 120 from moving horizontally relative to the connector 130 or the bottom board 200, thereby ensuring the performance and stability of the system.
