As shown in fig. 13, for how to fix the male metal shielding member 310 inside the male base, in this embodiment, an implementation manner is defined, where more than two fixing pieces 315 extending outwards are disposed on a side of the male metal shielding member 310 away from the bending end of the metal elastic piece 311, after one side of the fixing piece 315 is bent, a second bending portion 314 is formed, and bending directions of the first bending portion 313 and the second bending portion 314 are opposite, that is, an outwardly extending fixing piece 315 is disposed on a side of the male metal shielding member 310 opposite to the first bending portion 313, and then bending is performed on one side edge of the fixing piece 315, so as to form the second bending portion 314 shown in fig. 3; when needing to install, have the grafting chamber on the public end base, the bottom in grafting chamber has a plurality of through-holes, makes things convenient for the wearing out of public end module, consequently is provided with a plurality of recesses with second kink 314 looks adaptation in the bottom in grafting chamber.

The outer sidewall of the female metal shield 410 is provided with an opening slot 412 adapted to the metal protrusion 411, and the metal protrusion 411 is exposed in the opening slot 412 when the female metal shield 410 is fixed to the female base 400. Since the female terminal base 400 is inserted into the outer side of the male terminal base 300, the female terminal metal shield 410 needs to be mounted on the outer side of the female terminal base 400, and thus the open slot 412 is formed on the outer side wall thereof for better fixation, and then the female terminal metal shield 410 is inserted into the open slot 412 by inserting the metal protrusion 411 into the open slot 412 according to the position of the open slot 412.

On the female metal shield 410, a second opening 413 is formed between adjacent metal protrusions 411, and the second opening 413 is adapted to the interval between adjacent open slots 412. In this embodiment, in order to make the metal protrusions 411 embedded in the open slots 412, the second openings 413 are formed at the portions between the metal protrusions 411, i.e. the portions between adjacent metal protrusions 411 form hollows, which can be just inserted into the open slots 412 on the female terminal base, so that the installation of the female terminal metal shield 410 is more convenient, and the structure is more stable.
