The present invention relates to a device for connecting two electrical circuits (2, 17; 15, 16) by a connection which permits that the two circuits easily can be separated and reunited again at the same time as interference and scratching noise in the connection mechanism are avoided. A first carrier (14, 28) is movable around a shaft (1), which is fastened onto a second carrier (7, 29). The first carrier (14, 28) can easily be removed from the shaft (1) and refitted again. The first carrier (14, 28) has a projecting part (8, 23, 30), which presses against an electrically conducting elastomer (4, 18a-1, 21, 33) localized on the second carrier (7, 29). On the projecting part (8, 23, 30) there is an electrically conducting part (9, 20a-1, 24a-h), which is connected to a first electrical circuit (2, 17) localized on the first carrier (14, 28). The electrically conducting elastomer (4, 18a-1, 21, 33) is connected to a second electrical circuit (15, 16) localized on the second carrier (7, 29). By means of cooperation between the projecting part (8, 23, 30) and the elastomer (4, 18a-1, 21, 33), an electrical connection between the first (2, 17) and the second circuit (15, 16) is achieved.

La présente invention concerne un dispositif destiné à connecter deux circuits électriques (2, 17; 15, 16) par une connexion permettant de séparer et de réunir à nouveau facilement les deux circuits tout en évitant les interférences et le bruit de frottement dans le mécanisme de connexion. Un premier support (14, 28) est mobile autour d'un axe (1) lequel est fixé sur un second support (7, 29). Le premier support (14, 28) peut être retiré de l'axe (1) et remis en place facilement. Le premier support (14, 28) présente une partie saillante (8, 23, 30), laquelle exerce une pression contre un élastomère électroconducteur (4, 18a-l, 21, 33) placé sur le second support (7, 29). Sur la partie saillante (8, 23, 30) se trouve une partie électroconductrice (9, 20a-l, 24a-h), laquelle est connectée à un premier circuit électrique (2, 17) placé sur le premier support (14, 28). L'élastomère électroconducteur (4, 18a-l, 21,33) est connecté à un second circuit électrique (15, 16) placé sur le second support (7, 29). Par la coopération entre la partie saillante (8, 23, 30) et l'élastomère (4, 18a-l, 21, 33), on obtient une connexion électrique entre le premier circuit (2, 17) et le second circuit (15, 16).
