[0041] The elastic electrode needle 31 is in electrical contact with the circuit board support plate 2, and the vertical elastic electrode needle 32 is in electrical contact with the cylindrical base 1. The circuit board support plate 2 is plugged into the cylindrical base 1 for electrical contact, so that when the circuit board 3 conducts electrical signals, it is only necessary to contact the electrical connection end of the device to be connected with the cylindrical base 1.

This is an embodiment of the distribution of the exhaust holes 21.
