The insulating body 240 can better avoid the direct contact between the second conductive arm 272 and the substrate 211 , thereby avoiding the problem that an equipotential is formed between the second conductive arm 272 and the conductive terminal 274 , causing the card tray plugging state detection switch 270 to fail to work normally.

In another embodiment of the present application, the first surface 140 is disposed toward the substrate 211 , and the accommodating space 160 of the ejector mechanism is located on the side of the tray 100 away from the substrate 211 .

The second conductive arm 272 can be fixedly installed on the side of the insulating top plate facing the card tray 100, and the conductive terminal 274 is disposed on the side of the insulating top plate facing the card tray 100, and is connected to the housing 310 of the electronic device 300 after passing through the insulating top plate, so that The conductive terminal 274 may be grounded through the housing 310 . The insulating top plate is used to avoid direct contact between the second conductive arm 272 and the housing 310 , thereby avoiding the problem that the card tray insertion and removal state detection switch 270 cannot work normally due to the equipotential formation between the second conductive arm 272 and the conductive terminal 274 .
