La tête de connecteur de fiche de barre omnibus intensive comporte une tête (1) et une barre omnibus (2) électriquement connectées l'une à l'autre. La tête (1), qui présente une forme de T renversé, est constituée d'un corps principal rectangulaire plus étroit (1-1) et d'une partie racine plus large (1-2). La fiche de la barre omnibus (2) est pourvue d’une encoche (2-1) qui  correspond à la partie racine (1-2) de la tête (1) et dans laquelle la tête est encastrée. Deux côtés opposés de la partie racine (1-2) de la tête (1) dans le sens de la largeur sont respectivement connectés à la barre omnibus (2) par soudage de sections de connexion (3). Le procédé de fabrication de la tête de connecteur à fente comprend des étapes d'ébauchage, de modélisation, de revêtement et de soudage. Ledit procédé offre les avantages distincts d'une plus grande surface de contact de soudage, d'un soudage solide et à faible déformation, tout en évitant une consommation de métal à faible résistance coûteux, de sorte qu'une bonne conductivité électrique après connexion est assurée, ainsi qu'un procédé de fabrication à bas coût, simple et pratique.
