The two clamping spaces 2053 are arranged in an isolated manner, in the process that the end annular wall 303 abuts against the middle part of the elastic membrane layer 205 and moves towards the outward annular groove 204, the deformation space 206 is automatically divided into the two clamping spaces 2053 according to pressure uniformity, the two clamping spaces 2053 are uniform in shape and uniform in pressure, so that the pressure clamped on the periphery of the end annular wall 303 is uniformly distributed, the accurate and stable insertion of the connecting sheet 203 into the insertion cavity 304 is ensured, and the abutting connection between the first metal contact sheet and the second metal contact sheet is accurate.
The isolation between the two clamping spaces 2053 prevents the clamping spaces 2053 from pressure variations during clamping of the end annular wall 303, which would lead to destruction of the entire clamping structure.
