Abstract
Un dispositivo eléctrico perfeccionado previsto pa uso como, por ejemplo, reloj, calculadora u otro equipo de naturaleza semejante, que comprende un alojamiento de material eléctricamente aislante moldeado alrededor de porciones de un bastidor de conductores eléctricamente conductivo, estando formado el alojamiento con una cavidad dentro de la cual penetran porciones de terminal del bastidor de conductores, habiendo un componente eléctrico recibido en la cavidad, con contactos del componente conectados eléctricamente a las porciones de terminal del bastidor de conductores dentro de la cavidad del alojamiento, caracterizado porque las porciones de terminal del bastidor de conductores son elásticas y se han deformado por inserción del componente en la cavidad para agarrar así elásticamente los contactos del componente y establecer conexiones eléctricas entre los contactos del componente y las porciones de terminal del bastidor de conductores, y retener el componente en la cavidad del alojamiento.
