The utility model provides a circuit board device.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a circuit board device according to an embodiment of the present invention.
In the present embodiment, the circuit board arrangement includes a first circuit board 10 and a second circuit board 20; the first circuit board 10 is provided with a control module 11 and a golden finger socket 12, the second circuit board 20 is provided with a golden finger plug 21 matched with the golden finger socket 12, and the second circuit board 20 is plugged in the golden finger socket 12 through the golden finger plug 21. For example, the first circuit board 10 may be a server control motherboard, a data motherboard, or the like; the second circuit board 20 may be a solid state disk circuit board, a memory stick, an external electronic device circuit board, etc.
The gold finger receptacle 12 includes a first pin group 121 and a second pin group 122, the first pin group 121 may include one pin or a plurality of pins, and the second pin group 122 may include one pin or a plurality of pins. The first signal terminal X1 of the control module 11 is electrically connected to one of the pins of the first pin group 121, the second signal terminal X2 of the control module 11 is electrically connected to one of the pins of the second pin group 122, and the first signal terminal X1 and the second signal terminal X2 are respectively connected to the power VCC via a pull-up load R (e.g., a resistor); that is, the signal of the first signal terminal X1 is the signal of the pin in the first pin group 121 to which it is electrically connected, and the signal of the second signal terminal X2 is the signal of the pin in the second pin group 122 to which it is electrically connected.
Only when the gold finger plug 21 is aligned and plugged with the gold finger socket 12, the first signal terminal X1 and the second signal terminal X2 are in the first preset level state and the second preset level state in sequence. When the gold finger plug 21 is inserted into the gold finger socket 12, the pin electrically connected to the first signal terminal X1 is connected to the corresponding pin of the gold finger plug 21, and the pin electrically connected to the second signal terminal X2 is also connected to the corresponding pin of the gold finger plug 21, at this time, the pin electrically connected to the first signal terminal X1 is in a first preset level state, and the pin electrically connected to the second signal terminal X2 is in a second preset level state. When the golden finger plug 21 and the golden finger socket 12 are plugged and dislocated, a pin electrically connected with the first signal end X1 and a pin electrically connected with the second signal end X2 are short-circuited with pins not corresponding to the pins, and at the moment, the first signal end X1 and the second signal end X2 are not in a first preset level state and a second preset level state in sequence; it is possible that the first signal terminal X1 and the second signal terminal X2 are both in the second predetermined level state, and it is also possible that the signal terminal X2 are in the second predetermined level state and the first predetermined level state respectively. For example, the first predetermined level state is a high level state (1), and the second predetermined level state is a low level state (0).
When the control module 11 detects that the level states of the first signal end X1 and the second signal end X2 are the first preset level state and the second preset level state in sequence, the control module 11 determines that the gold finger plug 21 of the second circuit board 20 and the gold finger socket 12 of the first circuit board 10 are in alignment splicing, and there is no situation that splicing deviation and dislocation cause short circuit of adjacent pins, and at this time, the control module 11 can control the gold finger socket 12 of the first circuit board 10 to be powered on or feed back the splicing state of the gold finger plug 21 and the gold finger socket 12 to the host computer.
When the control module 11 detects that the level states of the first signal end X1 and the second signal end X2 are not the first preset level state and the second preset level state in sequence, the control module 11 determines that the gold finger plug 21 of the second circuit board 20 is not in splicing alignment with the gold finger socket 12 of the first circuit board 10, that is, splicing deviation and dislocation occur to cause short circuit of adjacent pins, and at this time, the control module 11 controls the gold finger socket 12 of the first circuit board 10 not to be powered on or feeds back the splicing state of the gold finger plug 21 and the gold finger socket 12 to the upper computer, so as to ensure the safety of the circuit board device.
When the control module 11 detects that the level states of the first signal terminal X1 and the second signal terminal X2 are both the high level state (1), the control module 11 may determine that the gold finger socket 12 is not plugged in the gold finger plug 21.
In the circuit board device of the present embodiment, the control module 11 is added on the first circuit board 10, the control module 11 is electrically connected to one pin of the first pin group 121 of the gold finger socket 12 on the first circuit board 10 by connecting to the first signal terminal X1 of the power VCC through a pull-up resistor, and is electrically connected to one pin of the second pin group 122 of the gold finger socket 12 on the first circuit board 10 by connecting to the second signal terminal X2 of the power VCC through a pull-up resistor, when the gold finger plug 21 of the second circuit board 20 is plugged into the gold finger socket 12 of the first circuit board 10, the control module 11 can determine whether the gold finger plug 21 and the gold finger socket 12 are in an aligned plugging state or a plugging deviation and dislocation state according to the level states of the first signal terminal X1 and the second signal terminal X2, so that when it is determined that the gold finger plug 21 and the gold finger socket 12 are in an aligned plugging state, the golden finger socket 12 is powered on, and when the golden finger plug 21 and the golden finger socket 12 are confirmed to be in the plugging deviation malposition state, the golden finger socket 12 is not powered on, so that the safety of the first circuit board 10 and the second circuit board 20 of the circuit board device is effectively ensured.
