Abstract: A sealed circuit board connector for electrically connecting a connector to a circuit board. The connector includes an interface housing which has at least one signal contact in the connection region and which has at least two press-in elements with press-in zones. The interface housing is designed with a contact area for a seal. The seal is arranged in the sealing region of the circuit board plug. The seal has a passage opening for the at least one signal contact or contacts and has in each case one opening for the at least two press-in elements.

Abstract: An electrical plug connector in the form of a solid contact pin that has a contact portion, a transition portion adjoining the contact portion, and a connection portion adjoining the transition portion for electrical connection to an electrical line by ultrasonic welding. The connection portion is formed from a first leg and a second leg and has at least one geometric wave refraction element for refracting waves during ultrasonic welding.
