The connector 30 may have various structures, preferably, the connector 30 may include a first connecting plate 40 and a second connecting plate 50 which are sequentially overlapped from bottom to top, one end of the first connecting plate 40 is provided with a first bent portion 41 connecting the first connecting plate 40 and the first elastic wall 10, the other end of the first connecting plate 40 is provided with a second bent portion 42 connecting the first connecting plate 40 and the first sub-pad 31, the first sub-pad 31 is parallel to the first connecting plate 40, and one side of the first sub-pad 31, which is far away from the first connecting plate 40, is welded on the circuit board, and on the first connecting plate 40, an installation portion 43 is reserved between the edge of the first sub-pad 31, which is far away from the second bent portion 42, and the first bent portion 41; one end of the second connecting plate 50 is provided with a third bending part 51 which is connected with the second connecting plate 50 and the second elastic wall 20, the adjacent side edge of the other end of the second connecting plate 50 is provided with a fourth bending part 52 which is connected with the second connecting plate 50 and the second sub-pad 32, the second sub-pad 32 is parallel to the second connecting plate 50, one surface of the second sub-pad 32, which is far away from the second connecting plate 50, is welded on the circuit board, the second connecting plate 50, the fourth bending part 52 and the second sub-pad 32 form a U-shaped groove 53, and the mounting part 43 is inserted in the U-shaped groove 53 from the side edge of the first connecting plate 40.

Thus, one end of the two ends of the first connection board 40 is bent upwards to form a first bent portion 41, the first bent portion 41 is continuously bent upwards and towards the middle of the first connection board 40 along the first bent portion 41 to form the first elastic wall 10, the first bent portion 41 connects the first connection board 40 and the first elastic wall 10, the other end of the first connection board 40 is bent downwards to form a second bent portion 42, the second bent portion 42 is continuously bent towards the direction parallel to the first connection board 40 and towards the middle of the first connection board 40 along the second bent portion 42 to form the first sub-pad 31, the second bent portion 42 connects the first connection board 40 and the first sub-pad 31, the edge of the first sub-pad 31 does not extend all the way to the end where the first bent portion 41 is located, but a certain space is left between the edge of the first sub-pad 31 and the end where the first bent portion 41 is located to serve as the mounting portion 43. Here, the first elastic wall 10, the first bent portion 41, the first connection plate 40, the second bent portion 42, and the first sub pad 31 may be regarded as a first sub elastic piece.

It should be noted here that when the tolerance of the patch is large, the area of the contact point is strictly required to ensure good connection, such as: when the contact point is arranged on the golden finger, the golden finger is required to cover the contact point of the elastic sheet.

In this embodiment, referring to fig. 4, the first bent portion 41 may be connected to and flush with an end of the first connecting plate 40, and as the first bent portion 41 is bent upward, the first bent portion 41 gradually narrows, and an edge of the first bent portion 41 does not change, and the edge gradually shortens toward the middle of the first connecting plate 40, so that the first elastic wall 10 is connected to and flush with the first bent portion 41, and the first elastic wall 10 extends upward and toward the middle of the connecting plate.

Referring to fig. 6, the third bent portion 51 may be connected to and flush with an end of the second connecting plate 50, and as the third bent portion 51 is bent upward, the third bent portion 51 is gradually narrowed, and an edge of the third bent portion 51 is not changed, and the edge is gradually shortened toward a middle position of the second connecting plate 50, so that the second elastic wall 20 is connected to and flush with the third bent portion 51, and the second elastic wall 20 extends upward and toward the middle of the connecting plate.

When the elastic connecting plate is inserted, the edge of the first bent part 41 without change and the edge of the third bent part 51 without change are respectively located at two side edges of the connecting plate, and the first elastic wall 10 and the second elastic wall 20 are spaced by a distance, so that the projection relationship in the scheme is formed.
