Then, when the front shell 11 and the back shell 12 are installed, the fixed shell 51 and the fixed cover plate 52 are moved respectively on the front shell 11 and the back shell 12 to make the fixed shell 51 and the fixed cover plate 52 close to each other, so that the connecting cable 41 is installed in the through groove, and the soft sealing member 53 is used to ensure the stability of the installation of the connecting cable 41 and the airtightness between the two.

[0091] When the front shell 11 and the back shell 12 are opened, under the action of the reset member 56, the reset plate 54 moves along the anti-deflection column 57 toward the fixed cover 52, thereby driving the connecting column 55 and the fixed cover 52 to move in the same direction, so that the fixed cover 52 and the soft sealing member 53 are away from the connecting cable 41, which makes it convenient to take and place the connecting cable 41.
