In addition, one of the electronic devices can be assembled or accommodated in the groove 221 on the insulator 2, the electronic device can be limited, the second lead-in part 321 of the second elastic arm 32 can be stably elastically led in with the electronic device, when the other electronic device is pressed on the electronic device, the two electronic devices are not easy to be misaligned, and then the two electronic devices can also form stable lead-in.

[0049] In the embodiment, the two electronic devices are a PCB board 4 and a sensor 5, the sensor 5 is assembled or accommodated in the groove 221 on the insulator 2 and is elastically contacted and led in with the second lead-in part 321 of the second elastic arm 32, the PCB board 4 is pressed on the insulator 2 and the sensor 5, the PCB board 4 is elastically contacted and led in with the first lead-in part 311 at the upper end of the first elastic arm 31, the PCB board 4 applies pressure to the sensor 5, and then the second lead-in part 321 of the second elastic arm 32 is more stably contacted with the sensor 5, and the conduction effect is better. The PCB board 4 and the sensor 5 can also be contacted and led in, of course, and can not be contacted and led in, and the selection is according to actual requirements.
