[0019] Please refer to figure 2 , which is a schematic diagram of the socket device 200 of the first embodiment. The slot device 200 has a slot 106 , a judging circuit 104 and a warning device 102 . The slot 106 is used for installing an expansion card, and the slot 106 has a sensing device 210 . Since most of the expansion cards are not completely installed in the slot, one end of the expansion card is not fully inserted into the slot, so the sensing device 210 is respectively provided with first sensing devices at the two ends of the slot 106 where the expansion card is installed. The point 212 and the second sensing point 214 . In most cases, the length of the slot 106 is set corresponding to the expansion card, so in this embodiment, the first sensing point 212 and the second sensing point 214 are respectively set at two ends of the slot 106 .
[0020] The judging circuit 104 is coupled to the first sensing point 212 and the second sensing point 214 , and judges whethe...

[0023] In the first embodiment, a light detector is installed in the slot as a sensing device to detect whether the expansion card is completely installed in the slot. However, not only the above methods can be implemented. The characteristics of each contact in the slot can also be used for application to achieve the same effect.
[0024] Please refer to image 3 , this figure is a schematic diagram of the socket device 300 of the second embodiment. Since the basic structure of this embodiment is substantially the same as that of the first embodiment, most components will not be repeated here.
[0025] Due to the multiple grounding points provided in the original slot 106 must be connected to the ground plane of the substrate, and when the expansion card is completely installed in the slot 106, all the grounding points will also form a ground loop on the expansion card. In this embodiment, the ground points located at both ends of the slot 106 are floated as the first sens...

[0028] In some special cases, for example, a single slot can be installed with various expansion cards of different lengths, or a design with various expansion cards of different lengths under a single specification. Floating and pulling up the signal with ground points at both ends of the socket may not be applicable in all situations. At this time, a special design can be made according to the definition of each pin in the electrical specification. For example, the adapter cards and slots of the PCI Express specification can solve the above problems through the ground point and the PRSNT# contact.
[0029] Please refer to Figure 4 , which is a schematic diagram of the socket device 400 according to the third embodiment of the present invention. At this time, the slot 402 is a PCI Express slot, and the first sensing point 412 in the sensing device 410 is a floating ground, and the second sensing point 414 is a PRSNT# contact. Since the PCI Express specification has expans...
