Referring to fig. 2, 3, 4 and 7, the elastic electrode terminal 60 is a bent structure with a certain elastic deformation performance, and is formed by continuously bending a strip-shaped metal blank along the length direction thereof, and is mainly used for pressing the gold finger terminal 30 to be electrically connected with the gold finger terminal 30 in a pressing contact manner, so as to establish an electrical conduction relationship between the first circuit board 20 and the second circuit board 50, one end of the elastic electrode terminal 60 is fixed on the second circuit board 50 by welding and electrically conducted with the second circuit board 50 (particularly, the second signal processing module 53 and the like) so as to be distributed on the lower surface side of the second circuit board 50 along the up-down direction, and the other end of the elastic electrode terminal 60 is used for elastically pressing the gold finger terminal 30 between the second circuit board 50 and the outer end 22.
