The shield shell is installed in the housing, which has a mounting hole formed in the housing. The terminal retaining body is inserted into the mounting hole of the housing and is accommodated in the shield shell. The cable assembly is inserted into the housing through the rear end of the mounting hole. The terminals of the cable assembly are inserted into the terminal retaining body, and the shield connector of the cable assembly mates with the rear end of the shield shell to electrically connect the cable shield layer to the shield shell. The sealing ring of the cable assembly is sleeved onto the cable and, together with the cable, seals the rear end of the mounting hole.
