Definitions

  • the first drip-proof member is disposed between a portion constituting the periphery of the opening of the first case and a portion constituting the periphery of the exposure opening of the cover, and the second drip-proof member.
  • the rotary electronic component 1 has the operation knob 100 that performs a circular motion (including an arc motion and a swing motion) around the axis K1 (see FIG. 2) on one surface side of the circuit board 160. Is provided between the operation knob 100 and the circuit board 160, and a detection means including a slider 130 and a sliding contact pattern 165 whose output is changed according to the movement of the operation knob 100 is provided.
  • the first and second cases 20 and 70 are housed in the first and second cases 20 and 70, and an opening H1 provided in the first and second cases 20 and 70 is partially exposed from the outer periphery of the operation knob 101.

Abstract

Cette structure anti-goutte d'un composant électronique comprend des emballage 250 (250a - 250d) disposé entre une zone environnante d'une ouverture H1 de premier et second boîtiers 20, 70 et une zone environnante d'une ouverture d'exposition 305 d'un couvercle 300. Les emballages 250 empêchent le liquide de pénétrer à partir de l'ouverture d'exposition 305 du couvercle 300 et de passer entre les premier et second boîtiers 20, 70 et le couvercle 300.
