Abstract

Un conjunto de suspension de cuchilla para un disyuntor de circuito comprende un pasador de pivote, un resorte de torsion, una cuchilla alargada y un portador de cuchilla. El resorte de torsion incluye una seccion lateral media, un par de patas de extremo dispuesta en lados opuestos de la seccion media, y un agujero lateral que se extiende a su través. La cuchilla incluye un contacto eléctrico montado en ella, una superficie inferior de apoyo, y una apertura lateral circular. El portador de cuchilla incluye pares primero y segundo de superficies de apoyo. Para ensamblar el conjunto de suspension de cuchilla, el resorte de torsion es colocado sobre la cuchilla con la seccion lateral media topando en la superficie inferior de apoyo de la cuchilla, con las patas de extremo dispuestas en lados opuestos de la cuchilla, y con el agujero lateral del resorte de torsion dispuesto en línea con la apertura circular en la cuchilla. En seguida, el pasador de pivote es insertado a través del agujero lateral en el resorte de torsion y a través de la apertura circular en la cuchilla. La combinacion de la cuchilla, el resorte de torsion y el pasador de pivote es entonces insertada en el portador de cuchilla con el par de patas de extremo topando en superficies de apoyo respectivas del primer par de superficies de apoyo y extremos opuestos del pasador de pivote topando en superficies de apoyo respectivas de dicho segundo par de superficies de apoyo.
