La présente invention porte sur un clavier équipé d'un support en plastique moulé par injection et utilisé pour un ordinateur portatif ou un ordinateur de bureau, et un procédé de production de celui-ci. Le clavier comprend une pluralité de capuchons de bouton (10) disposés à des intervalles, des branches en ciseaux (20), une pluralité d'éléments en silice colloïdaux élastiques (30), une pluralité de points de fixation de broches inférieures (40), un support de clavier (50) et un film de circuit imprimé (60) recouvrant la surface du support de clavier (50), la surface inférieure du capuchon de bouton (10) étant munie d'un point de fixation de broche supérieure. Après assemblage, les broches supérieures des branches en ciseaux (20) sont insérées dans et fixées sur les points de fixation de broches supérieures, les broches inférieures des branches en ciseaux (20) sont insérées dans et fixées sur les points de fixation de broches inférieures (40), la partie supérieure de l'élément en silice colloïdal élastique (30) est pressée contre la surface inférieure du capuchon de bouton (10), la partie inférieure de l'élément en silice colloïdal élastique (30) est positionnée sur le commutateur à bouton du film de circuit imprimé (60). Chaque point de fixation de broche inférieure (40) et le support de clavier (50) sont de la même pièce de plastique formée d'une seule pièce par moulage par injection de plastique au moyen d'un matériau plastique. La présente invention simplifie le processus de production, réduit le coût de production et améliore la précision d'assemblage et l'efficacité de l'assemblage automatisé.
