Abstract
A computer system comprising a chipset, a PCI Express connector with a preset bandwidth, and a PCI Express daughter board with a bigger bandwidth, is provided. The chipset is provided with a PCI Express controller with the preset bandwidth and electrically connects to the PCI Express connector. The PCI Express connector has a trench formed at an edge thereof. The PCI Express daughter board has a connecting portion with a number of golden fingers greater than a number of contacts of the PCI connector. The PCI Express connector is capable to pair the daughter board with part of the golden fingers located outside the connector.
Claims12
A computer system comprising:
- a central processing unit (CPU);
- a controller electrically connecting to the CPU;
- a connector electrically connecting to the controller and having an trench at an edge thereof;
- and
- a daughter board having a connecting portion with a plurality of golden fingers thereon, in which part of the golden fingers are accepted into the connector and electrically connecting to the connector;
- wherein a number of the golden fingers of the daughter board are greater than a number of the contacts within the connector, and the connecting portion of the daughter board with part of the golden fingers thereon extends outside the connector through the trench.
A main board adapting a daughter board comprising:
- a central processing unit (CPU);
- a controller electrically connecting to the CPU;
- and
- a connector electrically connecting to the controller and having a trench at an edge thereof for allowing a connecting portion of the daughter board with golden fingers deformed thereon to penetrate therethrough;
- wherein a number of the golden fingers of the daughter board are greater than a number of contacts within the connector, and the connecting portion of the daughter board with part of the golden fingers thereon penetrates through the trench to be outside the connector.
A connector for accepting a daughter board having a connecting portion with a preset number of golden fingers thereon comprising:
- a shell body having an upward slot therein, an edge of the slot having a trench penetrating through the shell body;
- and
- a plurality of contacts arranged along two opposing long sidewalls of the slot, in which a number of the contacts is smaller than the preset number, and in which the trench accepting the connecting portion has the excessive golden fingers located outside the shell body.
