Abstract

Un couvercle de câblage (14) est fixé à un boîtier de connecteur venant en prise avec un connecteur homologue et à partir duquel le câblage (20) est conduit vers l'extérieur. Une section de paroi du couvercle recouvre au moins une partie du câblage (20). La section de paroi comporte un évidement de dépouille (51), empêchant toute interférence avec un élément de CPA (15) assurant l'emplacement de mise en prise du boîtier de connecteur et du connecteur homologue. Et deux premières nervures (52) suivent la direction de sortie de conduction du câblage (20) vers l'extérieur, les deux premières nervures (52) étant disposées sur les deux bords latéraux de l'évidement de dépouille (51), selon une direction d'intersection croisant la direction de conduction vers l'extérieur.
