In this manner, each wire 20 is connected to the support port 30 for grounding.

The terminal is inserted into the inner space 12 through the wire passage portion 14 of the shield case 10 while the terminal is connected to the tip of the wire 20 so that the terminal is inserted into the housing 19. At this time, the wires 20 have passed through the wire holes 42 of the seal 40. Therefore, the seal 40 must be inserted into the through-hole 16, and one of the seal cases 46 is brought into close contact with one side of the seal 40, Causing the wires 20 to settle.

Next, the other seal case 46 is brought into close contact with the outer surface of the seal 40 on the opposite side so that the wires 20 are seated. In this state, the seal (40) and the seal case (46) are positioned inside the through hole (16). At this time, the seal case 46 entering the inside is located inside the case connection portion 34 of the support opening 30. [
