  • the accessory socket 1 can suppress the formation of a liquid pool on the contact terminal 3. Specifically, since the accessory socket 1 has the slit 42 and the slit 43 formed in the cylindrical portion 41, the liquid accumulated in the hole 412 flows from the slit 42 and the slit 43 to the slope portion 400 of the insulator 4, and the drain opening 25 is discharged outside. Therefore, the accessory socket 1 can suppress the formation of a liquid pool on the contact terminal 3.
  • the accessory socket 1 is formed with a slit 42 and a slit 43 so that when the conductive member 7 such as a coin enters the case 2 unintentionally, the conductive member 7 is unlikely to contact the case 2 and the contact terminal 3 at the same time. Therefore, compared with the case where the conductive member is fitted in the slit and contacts the case and the contact terminal at the same time, the occurrence of a short circuit is suppressed and the robustness is improved.
  • the slope portion 400 of the flange portion 40 of the insulator 4 is inclined, the liquid that has entered the case 2 easily flows from the slope portion 400 to the drain opening 25 as compared with the case where the accessory socket 1 is not inclined.
