  • Publication number: 20230363682
    Abstract: A seal portion 24 is arranged between a first fixing surface 222 and a second fixing surface 311. A biasing member 25 comes into contact with a tapered surface 332 of a male terminal 331 received in a female terminal 231 and applies a force in a direction in which the male terminal 331 and the female terminal 231 are moved closer to each other. In a state where the male terminal 331 is received in the female terminal 231, the seal portion 24 is compressed by being sandwiched between the first fixing surface 222 and the second fixing surface 311, and a periphery of the male terminal 331 and the female terminal 231 becomes in a state of being sealed by the seal portion 24.
