Patent number: 10555451Abstract: A method for mounting SMD components on contact springs in electric motors. In a first method variation, the SMD component is mounted on the base of a carrier of the electric motor, which has already been provided with a contact spring protruding into a cavity. As the SMD component is installed, the contact spring is pressed back such that no frictional or sliding contact arises during installation. In a second variation, the SMD component is mounted first and then a contact spring is inserted using a press tool. As the contact spring is inserted, the spring is held back such that likewise no frictional or sliding contact arises with the SMD component that has already been installed. This avoids damage to the SMD component caused by the contact spring during installation.Type: GrantFiled: September 7, 2015Date of Patent: February 4, 2020Assignee: Continental Automotive GmbHInventors: Werner Wallrafen, Daniel Muresan
