Abstract

La présente invention a pour but de fournir un dispositif de câblage, le corps de dispositif n'étant pas sensible à la distorsion même si une contrainte est appliquée. Le dispositif de câblage (A1) de la présente invention est pourvu d'un corps de dispositif (3) qui loge un ou une pluralité de commutateurs. Le corps de dispositif (3) est pourvu d'un corps (1) et d'un couvercle (2) qui viennent en prise l'un avec l'autre. Le corps (1) et le couvercle (2) sont pourvus d'une première section de mise en prise (31) et d'une seconde section de mise en prise (32). La première section de mise en prise (31) met en prise le corps (1) et le couvercle (2) l'un avec l'autre au niveau des deux extrémités du corps de dispositif (3) dans la première direction (direction longitudinale) du corps de dispositif. La seconde section de mise en prise (32) met en prise le corps (1) et le couvercle (2) l'un avec l'autre au niveau des deux extrémités du corps de dispositif (3) dans la seconde direction (direction latérale) qui est différente de la première direction.
