As shown in FIG. 1 and FIG. 2, in an embodiment, an electrical connection base 200 is illustrated. The electrical connection base 200 includes a pedestal 201 and a supporting element 100. The pedestal 201 is positioned on a first circuit board 301 and is electrically connected to the first circuit board 301. A socket 2011 is defined on the pedestal 201, and the socket 2011 can be configured to insert a second circuit board 303 for electrical connection to the first circuit board 301.

In an embodiment, the first circuit board 301 is a main board, and the second circuit board 303 is an expansion card. In another embodiment, the first circuit board 301 can also be a sub-circuit board electrically connected to the main board, and the second circuit board 303 can also be a cable or another component electrically switched by the electrical connection base 200.

The supporting element 100 includes an installation portion 10 and a support portion 20. Installation portion 10 is configured for an installation to an exterior of the pedestal 201. The installation portion 10 includes opposing first and second sides 101 and 103. The second side 103 of the installation portion 10 faces the first circuit board 301. A through hole 11 is defined in the installation portion 10. The through hole 11 penetrates the first side 101 and the second side 103. The installation portion 10 moves toward the first circuit board 301 and is set outside the pedestal 201, so that the pedestal 201 extends through the through hole 11. The socket 2011 is exposed from the first side 101 of the installation portion 10. The pedestal 201 may be entirely located in the through hole 11 or may partially protrude outside the through hole 11. The support portion 20 is set on the first side 101 of the installation portion 10. A first slot 21 is defined on the side of the support portion 20 facing the through hole 11, and the first slot 21 penetrates an end of the support portion 20 away from the installation portion 10.

When the second circuit board 303 is plugged into the socket 2011, the wall of the second circuit board 303 enters the first slot 21, a groove wall 211 of the first slot 21 contacts the second circuit board 303, and the support portion 20 supports the second circuit board 303 against strain and deformation.

In an embodiment, in order to facilitate entry of the wall of the second circuit board 303 in the first slot 21, a first guide surface 2111 is provided on the two opposite groove walls 211 of the first slot 21 facing away from the installation portion 10. The first guide surface 2111 is an inclined surface. In another embodiment, the first guide surface 2111 may also be a curved surface.

In an embodiment, the supporting element 100 further includes a resistance portion 30. The resistance portion 30 is positioned in the support portion 20 and in the first slot 21. The resistance portion 30 constrains and supports the part of the second circuit board 303 which is inserted into the first slot 21.

The resistance portion 30 is made of elastically deformable materials such as plastic. When second circuit boards 303 have different widths, the walls of the second circuit board 303 entering the first slot 21 bear against and compress the resistance portion 30, so that the resistance portion 30 deforms to closely fit second circuit boards 303 of different sizes.

One end of the resistance portion 30 is connected to the support rod 20, and the other end of the resistance portion 30 is a free end. The free end of the resistance portion 30 abuts on the second circuit board 303, which facilitates elastic deformation of the resistance portion 30 by different widths of second circuit boards 303.

In another embodiment, the resistance portion 30 may also be other elastic structures such as a spring in the form of a disk positioned in the first slot 21, and the resistance portion 30 will thereby bear on the second circuit board 303.

In an embodiment, there are two support portions 20. A support portion 20 is located on each side of the through hole 11. Opposite walls of the second circuit board 303 are inserted into the first slots 21 on the support portion 20, and the two support portions 20 provide support. In another embodiment, there may be only one support portion 20.

As shown in FIG. 3, FIG. 4, and FIG. 5, in an embodiment, a number of buckle parts protrude from the hole wall of the through hole 11, and the buckle parts can be buckled on a side of the pedestal 201 facing the first circuit board 301. That is, the buckle parts are located on a side of the pedal 201 away from the first side 101 of the installation portion 10. The buckle parts include two first buckles 111, two second buckles 113, and two third buckles 115. The two first buckles 111 are positioned on opposite walls of the narrow side of the through hole 11 close to the support portions 20, and the second buckle 113 and the third buckle 115 are positioned on the other two walls (the long walls) of the through hole 11. The two second buckles 113 are positioned on the same hole wall of the through hole 11, and the two third buckles 115 are positioned on the same hole wall of the through hole 11. There is a gap between a bottom wall 2013 of the pedestal 201 facing the first circuit board 301 and the first circuit board 301, and the first buckle 111 extends through through the gap and abuts the bottom wall 2013.

There is a gap between a bottom wall 2013 of the base 201 facing the first circuit board 301 and the first circuit board 301, and the second engaging portion 113 extends through the gap and abuts the bottom wall 2013. There is a gap between bottom wall 2015 of the base 201 facing the first circuit board 301 and the first circuit board 301, and the third engaging portion 115 extends through the gap and abuts the bottom wall 2015. The bottom wall 2013 and the bottom wall 2015 are on different planes.

In another embodiment, the buckle parts may be provided at other positions on the hole wall of the through hole 11, and the number of engaging portions may be one or more.

In another embodiment, the engaging portions may be omitted. The pedestal 201 and the hole wall of the through hole 11 have an interference fit or transition fit, and the hole wall of the through hole 11 presses against the outer peripheral wall of the pedestal 201. The pedestal 201 and the installation portion 10 are held firmly in place by the pressing force and friction between the hole wall of the through hole 11 and the pedestal 201.

In an embodiment, the supporting element 100 is an injection molding and an integrated structure. In the process of installing the supporting element 100 outside the pedestal 201, the buckle parts are elastically deformed and buckled outside the pedestal 201.

In another embodiment, the supporting element 100 may also be a composite structure of plastic and metal.

As shown in FIG. 6, and FIG. 7, in order to facilitate disassembly of the second circuit board 303 from the pedestal 201, the electrical connection base 200 includes an operating element 203. A second slot 12 is defined on the first side 101 of the installation portion 10. A third slot 13 is defined on the second side 103 of the installation portion 10, as shown in FIG. 5. The second slot 12 communicates with the third slot 13 and is located between the first slot 21 and the through hole 11. The second slot 12 also communicates with the first slot 21 and the through hole 11. The second circuit board 303 is substantially a rectangular plate. The side of the second circuit board 303 facing the first circuit board 301 can enter the second slot 12.

The operating element 203 includes a connecting portion 2031 and a contacting portion 2033. The connecting portion 2031 is positioned in the third slot 13 and partially protrudes out of the installation portion 10, it can be rotated. The connecting portion 2031 rotates and drives the contacting portion 2033 to enter or exit the second slot 12. When the contacting portion 2033 enters the second slot 12, the contacting portion 2033 contacts the second circuit board 303, and as the connecting portion 2031 rotates relative to the installation portion 10, the contacting portion 2033 abuts the second circuit board 303 and moves the second circuit board 303 along the first slot 21.

When the second circuit board 303 is inserted into the socket 2011, the second circuit board 303 can move toward the first circuit board 301 along the first slot 21. The second circuit board 303 presses against the contacting portion 2033 and drives the contacting portion 2033 to move until the contacting portion 2033 exits the second slot 12. The second circuit board 303 is thereby plugged into the socket 2011. The operating element 203 is relatively fixed under the second circuit board 303.

When the second circuit board 303 is disassembled, an external force is applied to the operating element 203, the connecting portion 2031 rotates relative to the installation portion 10, the contacting portion 2033 enters the second slot 12, and forces the second circuit board 303 away from the first circuit board 301 until the two are separated.

A mounting hole 1311 is defined in the groove wall 131 of the third slot 13 away from the through hole 11. The connecting portion 2031 comprises a shaft 2032. The shaft 2032 is rotatable in the mounting hole 1311.

In an embodiment, there are two second slots 12 and two third slots 13, and there are two connecting portions 2031 and two contacting portions 2033. The operating element 203 includes an operating portion 2035. One end of the operating portion 2035 is connected to an end of the connecting portion 2031 facing away from the contacting portion 2033, and the other end of the operating portion 2035 extends to one side of the connecting portion 2031. The operating portion 2035 connects the two connecting portions 2031. The external force for dismounting the second circuit board 303 is applied to the operating portion 2035, the leverage makes it easy to dismount the second circuit board 303.

In another embodiment, the number of second slots 12, third slots 13, and connecting portion 2031 and contacting portion 2033 of the operating element 203 may be one of each.

In another embodiment, the operating element 203 may be omitted, and the external force may be directly applied to the part of the connecting Portion 2031 protruding outside the installation portion 10.

In another embodiment, when the second circuit board 303 is an unusual shape, for example, the second circuit board 303 includes three sections with different heights, and the three sections can extend into the corresponding first slot 21, second slot 12 and through hole 11, the first slot 21 and through hole 11 can be disconnected from the second slot 12.
