https://en.m.wikipedia.org/wiki/ConnectorA terminal is the point at which a conductor from a component, device or network comes to an end.[1] Terminal may also refer to an electrical connector at this endpoint, acting as the reusable interface to a conductor and creating a point where external circuits can be connected
https://en.m.wikipedia.org/wiki/Terminal_(electronics)Eine Klemme dient in der Elektrotechnik zum lösbaren Anschluss oder der Verbindung von Drähten, Adern und Leitungen. Im angeklemmten Zustand muss ein dauerhafter, sicherer Kontakt gewährleistet sein. Das wird durch mechanische Fixierung (Schraube oder Feder) der angeschlossenen Leiter in einem leitfähigen Körper erreicht
