when the PRSNTB # of the gold finger on the OCP network card is in full contact with the motherboard connector spring, in the contact surface corresponding to the relative position between the boost positioning handle 20 and the adapter device body 10, the third position for setting the buckle 21 is determined on the boost positioning handle 20 corresponding to the first position determined on the adapter device body 10 for setting the card slot 11.
Specifically, fig. 3a is a schematic state diagram of a second position of the buckle provided in the embodiment of the present invention when the buckle is engaged with the first position of the slot; fig. 3b is an enlarged view of a state when the buckle at the second position is engaged with the slot at the first position according to the embodiment of the present invention; fig. 3c is a schematic view illustrating a state where the buckle at the second position is separated from the slot at the first position according to the embodiment of the present invention; fig. 4a is a schematic state diagram of a third position of a buckle according to an embodiment of the present invention, the third position of the buckle being engaged with a first position of a slot; fig. 4b is an enlarged view of a state where the buckle at the third position is engaged with the slot at the first position according to the embodiment of the present invention; fig. 4c is a schematic state diagram of a third position of the buckle being separated from the first position of the card slot according to an embodiment of the present invention.
It should be noted that, when the total length of the clip 21 and the space between the clips 21 is equal to the length of the card slot 11, and when the PRSNTB # of the gold finger on the OCP network card is in full contact with the motherboard connector spring, the clips 21 at the second position and the third position are both present in the card slot 11 at the first position, so as to perform a more stable fixing function.
With reference to the schematic diagram of the gold finger contact of the OCP network card shown in fig. 5, point a is the starting point of the insertion stroke (GND pin contacts with the shell fragment of the motherboard connector); point B is the starting point of contact between the gold finger PRSNTB # and the spring plate of the motherboard connector (also the starting point of the hot-plug operation); c is the contact point of the PRSNTB # of the golden finger and the spring plate of the motherboard connector (the starting point of the hot-drawing action); d is the contact point (the starting point of the pulling-out stroke) of the PRSNTB # of the golden finger and the elastic sheet of the motherboard connector when the OCP network card is completely inserted.
Therefore, the positions of the buckle and the slot are set according to the embodiment, so that the two states of the PRSNTB # of the golden finger of the OCP network card and the elastic sheet of the motherboard connector are a state just contacting and a state completely connecting, and therefore, the change condition of the electrical signal can be completely and accurately acquired.
