Abstract

La présente invention a trait à une structure de connexion électrique extra-plate qui permet au côté intérieur et au côté extérieur d'une chambre étanche à l'air d'être électriquement connectés de façon fiable tout en conservant l'étanchéité à l'air à l'intérieur de la chambre étanche à l'air. La structure de connexion électrique (1) connecte électriquement le côté intérieur (A) au côté extérieur (B) de la chambre étanche à l'air, lesquels côtés sont divisés au moyen d'une cloison (40). La structure de connexion électrique (1) comprend : un substrat (10) qui occlut une section d'ouverture (41) qui est formée sur la cloison (40) de manière à connecter le côté intérieur (A) au côté extérieur (B) de la chambre étanche à l'air ; et un premier connecteur (20) qui est prévu au moins sur le côté intérieur (A) ou le côté extérieur (B) par rapport au substrat (10) et qui s'étend de manière sensiblement parallèle au substrat (10). Un premier contact (22) du premier connecteur (20) est pourvu d'une pièce de contact élastique (22c) qui est mise en contact de façon élastique avec une plage de connexion conductrice (15) devant être connectée.
