The terminal 2 extends from the terminal hole 41. By the third step, the audio connector 100 can obtain a good waterproof effect.

  In the assembled audio connector 100, the U-shaped portion 224 of the second terminal 22 is located inside and outside the slot 2310 of the third terminal 23. The main part 211 of the first terminal 21, the main part 221 of the second terminal 22, and the main part 231 of the third terminal 23 are inserted into one side of the receiving hole 10 and the mating plug is inserted. It arranges in order along the horizontal direction orthogonal to the direction. The main body portion 241 of the fourth terminal 24 and the main body portion 251 of the fifth terminal 25 are sequentially disposed on the other side of the storage hole 10 along the lateral direction. The mating plug is inserted into one side of the housing hole 10 with the contact portion 212 of the first terminal 21, the contact portion 232 of the third terminal 23, and the contact portion 222 of the second terminal 22. The contact portion 252 of the fifth terminal 25 and the contact portion 242 of the fourth terminal 24 are sequentially arranged along the direction, and the mating plug is inserted into the other side of the storage hole 10. Are arranged in order. The solder connection part 213 of the first terminal 21, the solder connection part 233 of the third terminal 23, and the solder connection part 253 of the fifth terminal 25 are arranged in a straight line.
