Further, the upper convex section 3 is arc-shaped.

As can be seen from the above description, the arc-shaped upper convex section 3 not only facilitates processing, but also ensures the structural strength of the welding portion 1, and avoids the influence on the later welding effect caused by unexpected deformation of the welding portion 1 during storage and transfer.

Further, the number of the upper convex sections 3 is multiple.

As can be seen from the above description, the number of the upper convex sections 3 is large, which is beneficial to further improving the welding strength of the spring plate connector and the external member.

Furthermore, any two of the upper convex sections 3 are arranged in parallel.

As can be seen from the above description, any two of the upper convex sections 3 are arranged in parallel to facilitate the processing and manufacturing of the elastic sheet connector.

Further, the welding part comprises an elastic arm 2, one end of the elastic arm 2 is connected with the welding part 1, and the other end of the elastic arm 2 is located between the two upper convex sections 3.

According to the description, the upper convex section 3 can play a certain anti-hooking effect, and an anti-hooking structure is not required to be additionally arranged on the elastic sheet connector, so that the production steps of the elastic sheet connector are simplified, the production efficiency is improved, and the production cost is reduced.

Furthermore, the elastic arm 2 comprises a J-shaped force arm 5 and an n-shaped force arm 6 which are connected, the J-shaped force arm 5 is connected with the welding part 1, and one end, far away from the J-shaped force arm 5, of the n-shaped force arm 6 is located between the two upper convex sections 3.
