The second terminal assembly 220 has a second plate-shaped fixing portion extending longitudinally (to be described in detail later), a second terminal portion extending longitudinally (to be described in detail later), and a second connecting portion extending approximately transversely connecting the second plate-shaped fixing portion and the second terminal portion (to be described in detail later), wherein the second terminal assembly 220 and the first terminal assembly 210 are arranged to face each other and to be spaced apart from each other, wherein the spacing between the first plate-shaped fixing portion and the second plate-shaped fixing portion is greater than the spacing between the first terminal portion and the second terminal portion. That is, the first terminal assembly 210 and the second terminal assembly 220 are both Z-shaped. Therefore, the terminal in the present invention adopts a "Z-shaped" structure, which, compared with the conventional terminal structure, realizes a longer elastic arm and a smaller plug-in and pull-out force in a compact space, so that the elastic terminal has better floating performance.
