At this time, the slot 24 matches and engages with the protrusion 11, and the positioning plate 23 matches and engages with the groove 13. Then, the smaller diameter end of the outer shielding connecting ring 3 is inserted into the top of the through-hole shield shell 2. At this time, the first elastic part 21 is subjected to the outer shielding. The smaller end of the connecting ring 3 is squeezed, and the first elastic part 21 fastens the smaller end of the outer shielding connecting ring 3. Then, the positioning card 4 is sleeved on the outside of the outer shielding connecting ring 3. At this time, the positioning block 41 on the positioning card 4 is accommodated in the positioning groove 14 to prevent the positioning card 4 from rotating. Then, the cable 8 is passed through the positioning card 4, the outer shielding connecting ring 3 and the through-hole shielding shell 2 and positioned in the two-core through-hole shell 1.
