La structure de connexion électrique possède la partie pliable capable de se plier selon une courbe de carrosserie de véhicule, éliminant ainsi la limitation rendant difficile la flexion d'un fil d'aluminium classique, celui-ci pouvant uniquement être agencé linéairement. Les structures de connexion électrique maintiennent une certaine distance par rapport à la carrosserie de véhicule, de telle sorte que pendant le déplacement d'un véhicule, il est possible d'éviter que les structures de connexion électrique interfèrent avec la carrosserie de véhicule et produisent ainsi un son anormal. L'agencement positionnel rationnel d'un élément de fixation peut jouer un rôle dans la stabilisation des structures de connexion électrique. Une couche de blindage peut protéger contre des rayonnements électromagnétiques générés par un noyau d'aluminium, et une couche isolante est placée entre la couche de blindage et le noyau d'aluminium, empêchant ainsi à la couche de blindage de venir en contact avec le noyau d'aluminium.
